This is a requirement for eXecute + In Place (XIP) support. + * Add mmap() API with restricted capability (only for XIP support) + * Extend ROMFS test at /examples/romfs to verify mmap() and XIP support. + * Add support for Intel Hex format output using objcopy + * Completed the basic port of the NXP LPC2148 on the mcu123.com board. + The basic port includes successful booting, timer interrupts, serial console, + succesfully passing the examples/ostest, and a NuttShell (NSH) configuration. + * ARM architectures now support drivers/lowconsole.c + +0.3.16 2008-10-10 Gregory Nutt + * Added header files defining a common USB device controller architecture + * Added USB device side driver for the LPC214x + * Correct the frequency of system timer interrupts in the NXP LPC214x port + (off by 20x in nuttx-0.3.15) + * Add an option to set aside a separate stack for interrupt handling (ARM only). + This is useful when memory is constrained, there are multiple tasks, and + the interrupt stack requirement is high (as when USB is enabled). + * Added USB serial class device side driver (emulates Prolific PL2303 + serial-to-USB adaptor) + * Add LPC214x USB serial configuration; Add examples/usbserial test + * Added USB device side driver for the DM320 (untested at initial release) + * Fixed an error in a previous (post 0.3.15) check-in that broke the LPC214x + system timer. + * Fixed serial driver bugs related to (1) open counts and (2) recognizing + O_NONBLOCK on read. + * Fixed an error in read(); it was not setting the errno on errors returned + from the driver. + +0.3.17 2008-10-28 Gregory Nutt + * Incorporate patch "[2164503] nuttx-0.3.16 does not build for ARM with USB disabled" + * Reduced the amount of memory reserved for USB serial control requests. It + was unnecessarily large. + * Added LPC214x SPI1 driver to interface with MMC on mcu123.com board. + * Added a simple SPI-based MMC/SD block driver + * NSH: Add LPC214x-specific support to NSH; NSH now mounts any SD cards in the slot. + * FAT: Fix access to unaligned 32-bit values in partion table (start sector & size) + * Fixed a problem with a un-initialized variable in the USB serial driver. + * Added USB storage NXP LPC214x configuration + * Added a test for USB storage under examples/usbstorage + * Fixed a bug in the LPC214x USB driver: It was not properly clearing a HALTed + endpoints (other than EP) on receipt of CLEAR FEATURES request. + * Added USB storage class device side driver (BBB) + * Fixed a bug in the LPC214x USB driver: It was not properly handling request buffers + larger then the endpoint's max packet (DM320 driver also fixed, untested) + * Added logic to the USB device interface: A bit is needed to force the driver to + to terminate an IN transfer with a short packet (zero-length if necessary). + * Fix an error in the NXP LPC214x USB device driver that was causing corruption of + the request queue (M320 driver also fixed, untested) + * Correct another error in the NXP LPC214x USB device driver that caused read failures + when the request buffer size was larger than maxpacket. + * Numerous corrections/extensions to the USB tracing logic included in 0.3.16 (but + not integrated until 0.3.17) + * Fixed another bug in the NXP LPC214x USB device driver: After a stalled endpoint + is resumed (view CLEAR FEATURE), we must restart the IN (outgoing) queue. + +0.3.18 2008-11-16 Gregory Nutt + * Added port for the STMicro STR71x processor and configuration for the Olimex STR-P711 + board (STR71x testing is stalled because I have been unable to get OpenOCD to + communicate with my JTAG wiggler on Linux). + * Fix race condition workaround delay in LPC214X SPI logic. This was also the cause of the + very bad MMC/SD performance. + * Began port of the Hitachi SH-1 using the SH-1/US7032EVB1 board + * Re-built all configurations that use SDCC and Zilog toolchains to make sure they still + build (they didn't, but they do now). + * Fixed several erroneous "list empty" checks in the CAN driver. + * Hitachi SH-1 passes (reduced) examples/ostest; the examples/nsh test still fails. + There are remaining instabilities that make the port un-usable. The nature of these is + not understood; the behavior is that certain SH-1 instructions stop working as advertised. + This could be a silicon problem, some pipeline issue that is not handled properly by the + gcc 3.4.5 toolchain (which has very limit SH-1 support to begin with), or perhaps with the + CMON debugger. At any rate, I have exhausted all of the energy that I am willing to put + into this cool old processor for the time being. + * Renamed configuration item CONFIG_PROC_STACK_SIZE as CONFIG_IDLETHREAD_STACKSIZE: It now + only controls the size of the stack for the IDLE thread. Added CONFIG_USERMAIN_STACKSIZE: + This is the size of stack used with the user_start() thread is created. The two stacks + no longer have to be the same. + * Add a loop device that converts a file into a block device. + * Each NSH command can now be disabled through a configuration setting. All of these + settings make the configuration of NSH potentially complex but also allow it to squeeze + into very small memory footprints. + * Added a block to character (BCH) driver. This is kind of the reverse of the loop + device; it allows you access a block device like a character device. + * Added strcasecmp() and strncasecmp() + * NSH: Added the 'dd' command + * NSH: Added the 'losetup' command + * Fixed a FAT bug: After recent changes, it would mount a (invalid) FAT file system + even if the medium is not formatted! + * Corrected two important errors in FAT lseek implementation: (1) the sectors-per-cluster + value was being reset to "1" and (2) important lseek logic was omitted when the seek + position was zero. + * Fixed a bug in getopt(). It would fail if on certain combinations of terminal argument + types. + +0.3.19 2008-11-26 Gregory Nutt + * Add poll() and select() APIs (in the initial check-in, these work only with character devices) + * Add poll() methods to /dev/null, /dev/zero, pipes, fifos, and serial drivers. + * Add examples/poll for testing poll() and select() + * Fix hostile behavior of getc, fgetc, getchar, etc.: the serial driver was waiting for a + full buffer of read data before return. This means that getc would stall when it needed + to refill the input buffer. The old behavior (read full blocks) might be useful in other + contexts, so it is still available within the driver as a configuration option. + * Implement poll() and select() support for TCP/IP sockets + * Fixed an important bug in the TCP/IP buffering logic. When TCP/IP read-ahead is enabled + and not recv() is in-place when a TCP/IP packet is received, the packet is placed into + a read-ahead buffer. However, the old contents of the read-ahead buffer were not being + cleared and old data would contaminate the newly received buffer. + * Implemented support for connection backlog. The size of the backlog is specified by the + second argument of the standard listen() API. Hooks are provided to support poll()/select() + waiting for connections, with a subsequent call to accept() to use the backlogged connection. + * Fixed a minor bug in accept(). It should allow the address and addresslen values to be NULL + * Added first-cut definition for a framebuffer interface (and simulated framebuffer for testing + purposes only) + * Added fixed precision math support + * Added some color converson routines into what may become a real graphics library someday. + * Added a framebuffer driver for the DM320 (untested on initial check-in) + * Network: Add support for outgoing multicast addresses + * Added some rasterizers to the graphics library + +0.4.0 2008-12-06 Gregory Nutt + * Initial release of a tiny windowing system for NuttX + * Add fixed precision sin() and cos() (not well tested at initial check-in) + * Add an X11-based simulated framebuffer driver + * The simulated target now has an option (CONFIG_SIM_WALLTIME) that will let the simulation + run in more-or-less realtime. + * Added more extensive window support: frames, toolbars, etc. + * Added support for bitmap fonts + * Integrated the new font support with a font test in examples/nx + * Add documentation for NX graphics subsystem + +0.4.1 2009-02-06 Gregory Nutt + * Added board support for the ZiLog eZ80Acclaim! ez80f910200zco Development Kit. + * Fixed several compilation errors in fixed precision math library when built + against toolchains that do not support 64-bit type 'long long'. + * Fix errors in some function prototypes in dirent.h + * Add eZ80F91 EMAC driver + * Fix recvfrom() compilation error: only noted under ZDS + * Updated all ARM Make.def files to work with gcc 2.4.2 (However, there are + still some build issues associated with that toolchain in use of arm-elf-objcopy + -- see the TODO.txt list for details) + * Fix problems with Z16F and eZ80 compilation introduced with recent changes. + +0.4.2 2009-02-28 Gregory Nutt + + * M16C: Add support for the Renesas M16C MCU and the SKP16C26 StarterKit. However, + the target cannot be built because the GNU m16c-elf-ld link fails with + the following message: + + m32c-elf-ld: BFD (GNU Binutils) 2.19 assertion fail /home/Owner/projects/nuttx/buildroot/toolchain_build_m32c/binutils-2.19/bfd/elf32-m32c.c:482 + + Where the reference line is: + + /* If the symbol is out of range for a 16-bit address, + we must have allocated a plt entry. */ + BFD_ASSERT (*plt_offset != (bfd_vma) -1); + + No workaround is known at this time.

The + driver is basically functional and should mature prior to the 0.4.3 release. + * Implemented priority inheritance logic for POSIX semaphores. Because the pthread + mutexes are built on semaphores, they will have this property as well. + +0.4.4 2009-03-29 Gregory Nutt + + * examples/nsh: A debug option was left on that can (and does) cause + infinite loops and stack overflows. + * net/uip: Correct calculation of checksum on ICMP ping response. + * examples/dchpd: Added a tiny DHCP server example + * net/uip: Correct UDP bind behavior. It should select a valid port number + if it receives a port number of zero. + * netutils/dhcpd: correct for ZDS compiler. Fix issue with re-use of a + port number. Fixed a number of broadcast-related problems. + * eZ80Acclaim!: Add a tiny webserver configuration + * eZ80Acclaim!: Fixed an important bug in the EMAC Tx timeout logic. It was + always timing out when the load was heavy and worse, for some reason, + resetting the Tx function caused unexpected registers to be reset in + the Rcv function was well. + * Z80: Patch incorported: "[2696648] Z80: interrupt flag stored in parity bit" + (submitted by JPelletier). The is the same fix that was needed for the + eZ80 and fixed in 0.4.2. + * netutils: Added logic to support a simple wget() function + * examples/wget: Added a test for wget() (untested -- see NOTE) + * lib/strncasecmp: Fix cut'n'paste error in function name. + * NSH: Added wget command (untested -- see NOTE). + * examples/sendmail: A simple sendmail example (untested -- see NOTE) + + NOTE: Features related to wget and sendmail are not tested on the target platform + in this release and, hence, most likely have problems.

Also add an + alternative interface for so that (eventually) I can phase the sndblock + and recvblock methods and replace them with a single exchange method + * Build: objcopy fails with toolchains that use newer GCC and binutils. The + following arguments need to be included in the objcopy command line "-R .note + -R .note.gnu.build-id -R .comment" This has been fixed in arch/arm/src/Makefile, + but other architectures may have the same problem. Thanks to Dave Marples + for verifying this. + * configs/eagle100/ostest: Added support for the MicroMint Eagle100 board. + This board has a Luminary LM3S6918 Cortex-M3. Added a configuration to build + examples/ostest. + * arch/arm/src/lpc214x: Add configuration option to enable fast GPIO (vs. + legacy, "slow" GPIO) for LPC214x. + * arch/arm: Restructured the arch/arm directory structure to better support ARM + and Cortex-M3. + * sched/: pthread_create() must return a (non-negated) errno value on failure. + * configs/eagle100/nsh: Add a NuttShell (NSH) configuration for the Eagle-100 + +0.4.7 2009-05-29 Gregory Nutt + + * arch/arm/src/lm3s: Added an Ethernet driver for the LM3S6918 + * configs/eagle100/nettest: Added an examples/nettest configuration for the + Micromint Eagle100 board. + * Documentation/NuttxPortingGuide.html: Added a section on NuttX device drivers. + * configs/eagle100/httpd: Added an examples/uip configuration for the + Micromint Eagle100 board. + * arch/arm/src/lm3s: Added an SSI driver for the LM3S6918 + * examples/nsh: Added MMC/SD support for the LM3S6918 + * arch/arm/src/lm3s: Fix logic for setting and clearing output GPIOs (critical + fix!). + * drivers/mmcsd: Found numerous errors in current MMC/SD SPI driver. Bad frequency + calculation based on CSD settings, inappropriate timeouts, odd code that looks like + a bad search and replace. Also needs support for SDHC ver 2.x. New MMC/SD is + largely redesigned and probably non-functional in the first check-in. + * drivers/mmcsd: Changes verified on 4Gb Kingston microSHDC card and on a 2Gb + SanDisk microSDC card on the Eagle100 platform. + * fs/fat: With the 4Gb card, the first tests of FAT32 were (finally) performed. + Found and corrected a problem that prevented use of FAT32: It was not updating + the sector cache before checking the FAT32 FSINFO sector. + * configs/eagle100/*/Make.defs: Added configuration options that should make + it possible to build NuttX for the Eagle100 using CodeSourcery 2009q1 toolchain + and the devkitARM GNU toolchain. + * configs/mcu123-lpc214x/src: Corrected some logic in the LPC2148 SPI receive block + logic. Re-verified SDC ver1.x support with 1Gb Toshiba SDC, 1Gb PNY SDC, and + 4Gb Kingston SDHC. There are CMD0 issues with the 2Gb SanDisk SDC on this board. + * fs/fs_mount.c: Corrected error handling that could cause a deadlock on certain + mount() failures. + +0.4.8 2009-06-13 Gregory Nutt + + * lib/lib_*stream.c: Extend internal stream logic to support incoming streams. + * arch/arm/src/str71x: Serial output is now correct and timer interrupts are + working. The test at configs/olimex-strp711/ostest passes. This means that + the basic STR-P711 port is complete. + * configs/olimex-strp711/nsh: Add and verified a NuttShell (NSH) configuration + for the STR-P711. + * arch/arm/str71x/str71x_serial.c: The STR711 interrupt driven serial driver + finally works after some extradinary measures to handle missed interrupts. + NSH is fully functional on the Olimex STR-P711 board. + * example/nsh: Moved architecture specific files from NSH directory to board- + specific directories. + * config/olimex-strp711/src/up_nsh.c: Add an NSH board specific directory for + for the Olimex STR7P11 board. + * Fixed build of LM3X6918 using the CodeSourcery Windows native toolchain. There + were lots of issues with Cygwin paths and Cygwin symbolic links. These changes + may work with the devarmKIT as well, but that remains untested. + * The NXP LPC2148 and STR711 targets can now also be built using the CodeSourcery + or devkitARM Windows native toolchains. + +0.4.9 2009-06-26 Gregory Nutt + + * Add strtoll() and strtoull(); Add macros for atol() and atoll(). + * dup() and dup2() will now clone socket descriptors + * All socket descriptors are now cloned when a new task is started via + task_create(). + * Add configuration options to suppress or eliminate cloning of file + and/or socket descriptors when a new task is started by task_create(): + CONFIG_FDCLONE_DISABLE, CONFIG_FDCLONE_STDIO, CONFIG_SDCLONE_DISABLE. + * Use of C++ reserved word 'private' in C header files causes problems + for C++ that include them. + * Added 'binfmt' support to allow execution of programs in a file system, + binding to NuttX symbols. A custom format call NXFLAT is used; this + derives from http://xflat.sourceforge.net. At present is supports on + XIP execution from ROMFS file systems. Initial check-in is untested + and probably breaks many builds. + * examples/lib: Added qsort() + * examples/nxflat: Added support for symbol tables + * Correct logic that creates compiler include paths. On Cygwin, the + include paths for Cygwin-based GCC were being converted to windows + native paths. That causes many problems -- breaking dependencies + for one. + * Fixed an important bug in ROMFS. The initial XIP offset was set + incorrectly so if sector zero was read first, there was a bad read. + I don't know how it worked before. + * arch/arm/src/common/up_use_stack.c. Fixed a fatal stack setup error. + This file has been around for a long time, but I don't think it has + every been used before (i.e., prior to the NXFLAT logic) + +0.4.10 2009-08-08 Gregory Nutt + + * lib/: Added some basic regex-subset, pattern matching functions + * lib/: Greatly simplified mktime() and gmtime_r(). The Gregorian and + Julian time calculations were interesting, but not necessary in the + typical embeddd system. + * sched/: Added gettimeofday(). This implementation is simply a thin + wrapper around clock_gettimer(). + * lib/: Add gmtime(), localtime(), and strftime() + * binfmt/: Add exec(). This is just a wrapper that executes both + load_ and exec_module() in a more familiar manner. It is not consistent + with more standard exec() functions, however, because (1) it returns + and (2) it requires symbol table arguments. + * lib/: Add fileno() + * examples/ostest: Several of the tests used a big, hard-coded stack size + when creating test threads (16K stacksize). The stack size should + be controlled by the .config file or the OSTest won't work on platforms + with memory constraints. + * netutils/thttpd: An initial port of Jeff Poskanzer's THTTPD HTTP server. + See http://acme.com/software/thttpd/. + * examples/thttpd: A basic test program for THTTPD + * configs/eagle100/thttpd: A build configuration for THTTPD on the Micromint + Eagle-100 LMS6918 (Cortex-M3) board. + * configs/ntosd-dm320/thttpd: A build configuration for THTTPD on the Neuros + DM320 platform. + * lib/: Added strstr() and strpbrk(). + * net/recvfrom.c and net/accept(): Sockets now support some non-blocking + operations, specifically for (1) TCP/IP read operations when read-ahead + buffering is enabled, and (2) TCP/IP accept() operations when TCP/IP + connection backlog is enabled. + * fs/fs_fcntl.c and net/net_vfcntl.c: Minimal support provided for fcntl(). + It can, at least, be used to mark sockets as blocking or non-blocking. + * net/net_close.c: Fix bug in close(). If reference count not set to zero + then uip_tcpfree() will assert when DEBUG is enabled. + * net/accept.c: Fix bug in accept(). The logic expected parts of the + return address structure to be initialized or it would return an error. + +0.4.11 2009-09-16 Gregory Nutt + + * fs/fs_read.c and fs/fs_write.c. read() and write() to socket is the + same as recv() and send() with flags = 0.

Use of post-incremented + argument to macro caused strcasecmp() and strncasecmp() to fail. + * lib/lib_strstr.c: Length of substring off by one causes false alarm + sub-string matches. + * arch/arm/src/lm3s/lm3s_ethernet.c: Fix errors in LMS6918 FIFO length + handling. (1) The incorrect size of the Ethernet header was being + subtracted on outgoing messages (4 vs 14), which caused outgoing messages to + be a little too long. (2) The size of incoming FIFO messages is 6 bytes + larger than it expected (2 for the length and 4 for the FCS). The unhandled + extra two bytes of length cause the driver to sometimes read one too many + words from the received FIFO (corrupting the next queued receive packet, + if any). + * net/net_poll.c and net/uip/uip_tcpbacklog.c. Fixed an important race condition + bug in polling for connections. The logic worked if the poll was inplace + before the connection was received; but the poll failed to awaken if the + connection was already pending in the backlog when poll() was called. + * net/net_close.c. Fixed another important TCP/IP race condition bug: If + the host closes the TCP connection just before the target calls close(), then + the close operation may hang indefinitely! + * net/net_tcppoll.c. Removed an unnecessary check for outstanding, un-ACKed + data. The NuttX socket layer keeps track of ACKs and doesn't need this check; + removing the check should improve write throughput + * Add DEBUG configuration option to enable debug console output without disabling + optimization (and vice versa) + * Changed lots of occurrences of debug macro dbg() to lldbg(). dbg() uses + stdout to output debug data. That works fine unless (1) the dbg() macro + is interrupt logic and the interrupted task has redirected stdout! Most + changes were in uIP. + * net/uip/uip_tcpinput.c. Connection reference count was not being set correctly + when a socket is created by accepting a new connection. Since the reference + count is bad, such sockets are not successfully duplicated when being passed + to new tasks. + * net/net_clone.c. Similarly, after a socket is cloned, its reference count + was not being initialized. + * lib/lib_strstr.c. Improperly incremented pointer could cause comparison + failures. + * net/. Connection reference count must always be set to zero before calling + uip_tcpfree() or it could trigger a DEBUGASSERT that verifies that the + reference count is zero before freeing a connection structure. + * net/uip/uip_listen.c. uip_accept() consulted the wrong list to find the + listener on a socket. The previous logic worked most of the time, but + occasionally picked the wrong listener. + * net/net_close.c and net/net_sockets.c. Sockets were not being closed + when a task exits. If many server tasks are created and exit without closing + sockets (such as with CGI tasks), then eventually, you will run out of sockets. + * netutils/thttpd. Basic functionality of THTTPD is complete. This includes + serving up files from a file system and executing NXFLAT-based CGI programs + and pipe the stdout back to the HTTP client. + +0.4.12 2009-10-17 Gregory Nutt + + * arch/arm/src/stm32 and configs/stm3210e-eval. Added basic support for the + STMicro STM32, Cortex-M3 MCU. The specific port is to the STMicro STM3210E-EVAL + development board based around the STM32F103ZET6 MCU. + * configs/stm3210e-eval/RIDE. Added a basic STMicro RIDE7 project that can be + used to perform basic STM32 board bring-up (due to RIDE7 size limitations, it + cannot be used for the full NuttX bring-up). + * configs/stm3210e-eval/ostest. The STM32 now passes the basic NuttX OS test + at examples/ostest. The rest should be a piece of cake. + * configs/stm3210e-eval/nsh. Added NuttShell (NSH) example. + * configs/stm3210e-eval/src/stm32102e-internal.h. Fix on-board LED GPIO definitions. + * arch/arm/src/stm32/src/stm32/stm32_dma.c. Added DMA channel support for the STM32 + * arch/arm/src/stm32/src/stm32/stm32_spi.c. Added a DMA-based SPI driver for the STM32. + * arch/arm/src/stm32/src/stm32/stm32_serial.c. Finished interrupt-driven, + USART console driver. This makes NSH work perfectly. + * Things left to do for the STM32 deferred to the 0.4.13 release: USB device driver, + LCD driver and NX bringup on the eval board's display and MicroSD support. An SPI + driver was included in the 0.4.12 release, but is not yet tested. + +0.4.13 2009-11-04 Gregory Nutt + + * include/nuttx/mtd.h. Added a simple interface definition to support some + FLASH, EEPROM, NVRAM, etc. devices. + * driver/mtd/m25px.c. Added a driver for SPI based FLASH parts M25P64 and M25P128. + * configs/stm3210e-eval/usbserial. Add a USB serial configuration for the STM32. + Depends on the STM32 USB driver. + * arch/arm/src/cortexm3/up_switchcontext.S & up_svccall.c. Made an improvement + to context switching. There are two types of context switches: interrupt + context switches and background/user context switches. This change should + improve the performance of those background/user context switches by a factor + of about two. + * arch/arm/src/stm32/: Fix several typos in the serial logic. It turns out + that these typose don't make any difference as long as you use only one + serial port and all uarts are configured the same. But the typos are bugs + waiting to happen in any other configuration. + * arch/arm/src/stm32/: You have to configure CTS/RTS function pins for USART + 2 and USART 3 even if you are not using flow control. + * arch/arm/src/stm32/stm32_usbdev.c: Added a USB device-side driver for the + STM32. NOTE: This is an early release of the USB driver. There is at least + one known issue. The examples/usbserial test only executes correctly under + certain conditions (see the full bug description in the TODO list). + * arch/arm/src/stm32/stm32_rcc.c: Fixed an error in clock initialization. + On some boards (none of mine), the HSE (high speed external clock) delay + loop times out if the optimization level is high. The STM32 then falls + back to the HSI (internal clock), and the system clock is too slow by a + factor of 11.1%. This was fixed by simply add the volatile storage class + to the timeout loop counter + * arch/arm/src/stm32/stm32_irq.c: Fixed a critical bug in the interrupt + control logic. The wrong register was being used for interrupts in a + certain range. Worked fine until you try to use an interrupt in that + range! + +4.14 2009-12-02 Gregory Nutt + + * arch/arm/src/stm32/stm32_gpio.c: Add support for configure an input GPIO + to generate an EXTI interrupt. + * config/stm3210e-eval/src/up_buttons.c: Add support for on-board buttons. + * include/nuttx/rwbuffer.h: Add generic support for read-ahead buffering + and write buffering that can be used in any block driver. + * include/nuttx/wqueue.h: Added a generic worker thread that can used to + defer processing from an interrupt to a task. + * include/nuttx/sdio.h: Defines a generic SD/SDIO interface can can be + bound to a MMC/SD driver to provide SDIO-based MMC/SD support. + * drivers/mmcsd/mmcsd_sdio.c: Provides an SDIO-based MMC/SD driver. + * arch/arm/src/stm32/stm32_sdio.c: Provides an STM32 implementation of + the SDIO interface defined in include/nuttx/sdio.h. + * fs/fs_mount.c: Correct error handling logic. If the bind() method + fails, then a reserved node is left in the tree. This causes subsequent + attempts to mount at the location to fail (reporting that the node + already exists). This is a problem for block drivers for removable + media: The bind method could fail repeatedly until media is inserted. + * arch/arm/src/stm32/chip.h & stm32_dma.c: Fixed several definitions + that can cause compilation errors when DMA2 is enabled. + * arch/arm/src/stm32/stm32_dma.c: Integrated and debugged STM32 DMA + functionality that was added in 0.4.12. + * configs/stm3210e-eval/usbstorage: Add a configuration to exercise + the STM32 with the USB mass storage device class example + (examples/usbstorage). + * configs/mcu123-lpc214x/up_usbstrg: Move LPC-specific code from + examples/usbstorage to configs/mcu123-lpc214x. + * configs/stm321e-eval/up_usbstrg: Add STM32-specific logic for the + examples/usbstorage test. + * arch/arm/src/stm32/stm32_usbdev.c: Fix bugs in STM32 USB device-side + driver: (1) Need to disconnect after reset received, (2) Status setup + to recover from stall on TX endpoint. + +5.0 2009-12-21 Gregory Nutt + + * arch/hc: Adding framework to support m68hc11/12 + * configs/demo9s12ne64: Configuration to support Freescale DEMO9S12NE64 + development board (MC9S12NE64 m68hcs12 processor). + * drivers/mtd/ftl.c: A FLASH translation layer (FTL) has been implemented. + This layer will convert a FLASH MTD interface into a block driver that + can be used with any file system. Good performance of this layer will + depend upon functioning write buffer support! + NOTE: FTL support is untested as of the initial check-in. + * Numerous minor changes for m68hc12 to eliminate compilation errors and + warnings due to the fact that it uses 16-bit integer types and for casts + between uint32 (32-bits) and an mc68hc12 pointer (16-bits). + * sys/types: Size of off_t and blkcnt_t should not depend on size of + int in the architecture; Removed non-standard type STATUS + * include/: Added header files stdint.h, stdbool.h, cxx/cstdint, and + cxx/cstdbool + * Changed ALL references to non-standard fixed-size types (like uint32, + ubyte, etc.) to standard types (like uint32_t, uint8_t, etc.) from + stdint.h. Use type bool and {true, false} from stdbool. This effected + most of the files in the system! Almost all configurations have been + re-built and many have been re-verified in order to get confidence in + these changes. + * graphics/ and examples/nx: Fix numerous build errors that have been + introduced lately. NXGL has suffered some bit-rot from not being used + in some of the most recent ports. + * The misc/pascal NuttX add-on package has been updated to use the new + standard types from stdint.h and stdbool.h and re-integrated with NuttX. + The released pascal-2.0 will be the first version that contains the + compatible changes. + * arch/arm/src/lm3s/lm3s_ethernet.c: Fixed an important bug in the LM3S + Ethernet driver: If full packet is received, the packet-too-big check + will fail because it needs to subtract 6 from the packet size (to + account for the 2-byte packet length and the 4-byte packet FCS in the + FIFO). + * net/accept.c: Fixed a bad assertion (only happens when debug is enabled). + * net/send.c net/uip/uip_tcpseqno.c: Fixed a critical error in the TCP/IP + logic. The NuttX port of uIP imcludes logic to send data ahead without + waiting for ACKs from the recipient; this greatly improves throughput. + However, the packet sequence number was not being updated correctly and, + as a result, packets were not be ACKed by the recipient and transfers + would sometimes stall. This is a very important bug fix (in fact, I + don't understand how TCP/IP worked at all without this fix???) + * include/nuttx/arch.h and arch/*/common/up_udelay.c: Change argument + of up_udelay() to type useconds_t to avoid warnings when sizeof(int) + is 16-bits. + * drivers/mmcsd/*: Add casts in constant expressions to avoid warnings + when sizeof(int) is 16-bits. + +5.1 2010-01-30 Gregory Nutt + + * arch/arm/src/lpc313x and arch/arm/include/lpc313x: Added framework + to support the NXP LPC3131. + * Add configs/ea3131. The LPC3131 port for the Embedded Artist EA3131 + (LPC3131) is code complete and waiting for me to get hardware in + hand. + * arch/arm/src/sam3u, arch/arm/include/sam3u, and configs/sam3u-ek - + Added the basic framework needed to begin a port for the SAM3U-EK + development board. + * lib/lib_crc32.c: Add CRC32 logic by Gary S. Brown to lib/. This is + the larger (but faster) table look-up version of the CRC32 algorithm. + * configs/ea3131/tools: Added a tool to create a image suitable for + use with the LPC313x bootloader. + * configs/sam3u-3k/ostest: Completed verification of the basic NuttX + OS test for the SAM3U. + * arch/arm/src/common/up_createstack: stack was always been cleared + when it was allocated. This is a good feature for monitoring the + stack during debug, but really hurts thread start-up performance. + Clearing is now done if CONFIG_DEBUG=y only. Changes was only made + for arm, but really should be made for all architectures. + * configs/sam3u/nsh: Added NSH configuration for SAM3U + +5.2 2010-03-18 Gregory Nutt + + * arch/arm/src/sam3u/sam3u_pio.c: Fix an address calculation error + that caused ports B & C to get mapped to the PIOA base address. + This is an important bugfix!

This logic is only in place in + the arch/arm/src/Makefile for now. + * arch/arm/src/lpc17xx/lpc17_internal.h: Add missing parentheses in + macros definitions (patch submitted by Tiago Maluta). + * Documents/NuttxPortingGuide.html, configs/README.txt, etc. - + Replaced CONFIG_EXAMPLE with CONFIG_APP_DIR (see documents for + description). This allows NuttX application code to be built + outside of the examples/ directory. + + For people who have their own configurations and/or Makefiles, + you will need to make a couple of changes: + + - Replace all occurrences of CONFIG_EXAMPLE=foobar with + CONFIG_APP_DIR=examples/foobar in all of the configuration + files. + - Replace any occurrences of examples/$(CONFIG_EXAMPLE) with + $(CONFIG_APP_DIR) + - Replace any occurrences of lib$(CONFIG_EXAMPLE)$(LIBEXT) + with libapp$(LIBEXT) in your Makefiles. + - Check any other occurrences of CONFIG_EXAMPLE. + + * arch/arm/src/lpc313x/lpc313x_spi.c: Fix compilation error when + when CONFIG_DEBUG is enabled. + * arch/arm/src/lm3s and arch/arm/include/lm3s: Support for the + lm3s8962 contributed by Larry Arnold. + * configs/lm328962-ek: Support for the TI/Stellaris EKC-LM3S8962 + board (also contributed by Larry Arnold). + * arch/arm/src/lpc313x/lpc313x_boot.c: The call to lpc313x_boardinitialized() + should not be conditioned on CONFIG_ARCH_LEDs being defined! + * arch/arm/src/lpc313x/: APB0 and APB1 cannot lie in different + sections; they are too close together. + * arch/arm/src/lpc313x/lpc13x_boot.c: Resetting all of the clocking + had a side effect of wiping out the first 6 words of memory where the + interrupt vectors are located (and also not resetting the fractional + dividers). This is not usually noticeable because the IRQ vectors + are after this point, but really causes problems if you want to handle + data and prefectch aborts which are within this zeroed region. + +5.11 2010-10-01 Gregory Nutt + + * configs/ea3131/src/up_fillpage.c: Added new configuration item + CONFIG_PAGING_BINPATH. If CONFIG_PAGING_BINPATH is defined, then it + is the full path to a file on a mounted file system that contains + a binary image of the NuttX executable. Pages will be filled by + reading from offsets into this file that correspond to virtual + fault addresses. up_fillpage.c implements logic to perform page + files using the CONFIG_PAGING_BINPATH file. + * configs/mbed: Add configuration to support the mbed.org LPC1768 + board (Contributed by Dave Marples). + * sched/sem_wait.c and sem_waitirq.c: Eliminate a race condition + that can occur when a semaphore wait is interrupt by a signal. + (see email thread: https://groups.yahoo.com/neo/groups/nuttx/conversations/messages/530) + * drivers/mtd/at45db.c: Add a driver for the Atmel AT45DB161D 4Mbit + SPI FLASH part (untested on initial check-in). + * arch/arm/src/lm3s and arch/arm/include/lm3s: Corrections for the + lm3s8962 port contributed by Larry Arnold.

But it + is still a long way from complete. + * arch/*/src/*/*_sigdeliver.c: Fixed a serious error in the signal + trampoline logic. Essentially, interrupts are re-enabled while the + signal handler executes, but the logic to re-disable the interrupts + before returning from the signal handler trampoline was missing. Under + certain circumstances, this can cause stack corruption. This was + discovered by David Hewson on an ARM9 platform, but since the code + has been leveraged, the bug has been propogated from ARM to Cortex-M3, + AVR32, M16C, SH1, ZNEO, eZ80, Z8, and Z80 -- almost every architecture. + The correction has been incorporated for all architectures but only + verified on a few. + +5.13 2010-11-09 Gregory Nutt + + * lib/lib_strnlen.c: Added POSIX 2008 strnlen() function.

We have a good AVR32 port! + * configs/avr32dev1/nsh: Added a configuration to support the NuttShell + (NSH). As of this writing, here is a problem receiving serial data (this + is, very likely, my hardware setup). + * lib/lib_open.c: Fix an error in fdopen when a valid file descriptor does + not refer to an open file. + * configs/olimex-lpc1766stk: Add support for the Olimex LPC1766-STK + development board. The OS test and NSH configurations (only) have been + verified. + +5.14 2010-11-27 Gregory Nutt + + * configs/olimex-lpc1766stk/nettest: Add examples/nettest configuration to + verify the LPC17xx Ethernet driver currently under development. + * arch/arm/src/lpc17xx/lpc17xx_ethernet.c/.h: Began development of + the LPC17xx Ethernet driver. Driver in CVS functional after 2010-11-23. + * sched/timer_settime.c: Fix an error in set-up of a one-shot POSIX timer. It + was using the repititive timer value (which is zero in the one-shot case), + always resulting in a 10Ms timer! Found and fixed by Wilton Tong. + * arch/arm/src/lpc17xx/lpc17_vector.S, stm32/stm32_vector.S, lm3s/lm3s_vector.S, + sam3u/sam3u_vector.S: Fixed a hard fault problem that can occur if certain + types of interrupts are pending at the time another interrupt returns + (SYSTICK). This has not been verified on all plaforms, but is a critical + fixed that is needed by all Cortex-M3 NuttX users. + * configs/olimex-lpc1766stk/thttpd: Add a THTTPD configuration for the + Olimex LPC2766-STK board. Verified successfully. + * net/uip/uip_tcpappsend.c: Correct an important logic bug in some uIP state + data the is used to manage retransmissions. The uIP logic was incompatible + with the retransmission logic of net/send.c in one place. The final error + was that the final packet in a sequence of packets was too large! In the + THTTPD example, this would leave some garbage at the bottom of the display + (or worse). I don't know why I haven't see this bug before??? + * net/uip/uip_tcpinput.c: The change to uip_tcpappsend.c unmasked an + additional error in the TCP sequence number handling. This sympom was that + the send() function would hang with outstanding, unacknowledged data (with + no re-transmit requests). The was due to differences in sequence number + handling in send() and in uip_tcpinput.c; uip_tcpinput.c thought (incorrectly) + that all of the bytes were acknowledged; send.c knew that they were not. + +5.15 2010-12-12 Gregory Nutt + + * net/uip/uip_tcpaddsend.c and net/send.c: Another place where the TCP sequence + number problem "fixed" in 5.14 might occur. + * net/send.c: Check if the destination IP address is in the ARP table. If + not, then don't consider the packet sent. It won't be, an ARP packet will go + out instead. This improves behavior, for example, on the first GET request + from a browser. + * arch/arm/src/lpc17xx/lpc17_emacram.h and lpc17_allocateheap.c: The Ethernet + logic was using all of AHB SRAM Bank0 for Ethernet packet buffers (16K). An + option was added to limit the amount of SRAM used for packet buffering and to + re-use any extra Bank0 memory for heap. configs/olimex-lpc1766stk/nettest + now uses only 8K at the beginning of Bank0; the 8K at the end of Bank0 is + included in the heap + * arch/arm/src/lpc17xx/lpc17_ssp.c: Fix compilation errors when SSP1 is + selected. + * configs/olimex-lpc1766stk/nsh: Enable network and SD/MMC card support in + NSH. Networking and telnetd interface as well as SPI-based microSD are + now functional. + * examples/nsh/nsh_netinit.c: Fix NSH bug. If CONFIG_NET is selected, but + CONFIG_EXAMPLES_NSH_TELNETD is not selected, then the network is never + initialized and bad things happen if you try to ping. + * drivers/lcd: Add header files for the Phillips PCF8833 LCD controller and + for the Epson S1D15G10 LCD controller. A driver for the Nokia 6100 LCD is + coming. + * include/nuttx/spi.h and almost all other SPI files: Added an optional + cmddata() method to the SPI interface. Some devices require an additional + out-of-band bit to specify if the next word sent to the device is a command + or data. This is typical, for example, in "9-bit" displays where the 9th bit + is the CMD/DATA bit. The cmddata method provides selection of command or data. + * drivers/lcd/p14201.c: Now uses the cmddata() method of the SPI interface. + * arch/arm/src/lpc17xx/lpc17_usbdev.c: LPC17xx USB driver now appears to + to be fully functional. examples/usbstorage configuration verified (the + examples/usbserial configuration is untested). + * drivers/usbdev/usbserial.c and usbstorage.c: All USB class drivers need + to call DEV_CONNECT() when they are ready to be enumerated. That is, + (1) initially when bound to the USB driver, and (2) after a USB reset. + * drivers/lcd/nokia6100.c: A driver for the Nokia 6100 LCD. This driver + has not be verified as of the initial check-in. + * configs/olimex-lpc1766stk/nx: A NX graphics configuration for the Olimex + LPC1766-STK board using the Nokia 6100 LCD driver. This configuration has + not been verified as of the initial check-in. + * include/nuttx/spi.h: the SPI_SETBITS macro was calling the setmode method. + This is a very important bug-fix in some usages. + +5.16 2011-01-10 Gregory Nutt + + * include/nuttx/usb: Created new directory. Moved all usb-related header + files to this new directory. Created a skeleton for a new USB host header + file + * drivers/usbhost: Add USB host "registry" where connect devices can be + matched with the correct USB class driver. + * arc/arc/src/lpc17xx/lpc17_usbhost.c: Add a simple USB host driver for + the NXP lpc17xx. + * drivers/usbhost: Add generic USB device enumeration logic. + * drivers/usbhost: Add a USB host class driver for the (Bulk-Only) USB + Mass Storage Class. + +5.17 2011-01-19 Gregory Nutt + + * include/nuttx/usb: rename usb_storage.h to storage.h. + * arch/arm/src/lpc17xx/lpc17_usbhost.c: Add support for low-speed devices. + * drivers/usbhost/usbhost_skeleton.c: Template for new class drivers + * include/nuttx/usb/hid.h and drivers/usbhost/usbhost_hidkbd.c: New + files for HID keyboard support. + * arch/arm/src/lpc17xx/lpc17_usbhost.c: Will now handle multiple + concurrent transfers on different endpoints (still only one TD per + endpoint). All methods are protected from re-entrancy; lots of re- + structuring in preparation for interrupt endpoint support. + * arch/arm/src/lpc17xx/lpc17_usbhost.c: Add support for periodic + interrupt transfers. + * examples/hidkbd: Added a simple test for the USB host HID keyboard + class driver. + * configs/olimex-lpc1766stk/hidkbd: Added a configuration to build the + USB host HID keyboard class driver test for the LPC17xx. + * Ran the tool CppCheck (http://sourceforge.net/apps/mediawiki/cppcheck) and + fixed several errors in the code identified by the tool. + +5.18 2011-02-27 Gregory Nutt + + * Incorporate several uIP patches from http://gitweb.aeruder.net/?p=uip.git;a=summary. + - Lost SYNACK causes connection reset + - Fix missing UDP stats for sent/received packets + - Added support for Cygwin as development/test platform. + * configs/demo9s12ne64: Integrate new buildroot-1.9 m8s12x toolchain. + * 'uname -o' is used throughout the build logic in bash scripts and also in + Make.defs files in order to distinguish between Cygwin and Linux. However, + the -o option is not standard and is not supported under, for example, OS-X or + Solaris. This was solved by changing all 'uname -o' references to the more + complex: 'uname -o 2>/dev/null || echo "Other"' + * drivers/usbhost/usbhost_enumerate.c: Add logic to get the VID and PID. This + is necessary in order to support vendor-specific USB devices. + * examples/wlan, configs/olimex-lpc1766stk/wlan, drivers/usbhost/usbhost_rtl8187.c, + Add infrastructure to support RTL18187 wireless USB. + * configs/nucleus2g: backed out USB host changes... wrong board. + * Renamed arc/hc/include/mc9s12ne64 and src/mc9s12ne64 to m9s12. That name is + shorter and more general. + * The NuttX repository has been converted to SVN and can now be found here + http://svn.code.sf.net/p/nuttx/code/trunk/ + * configs/mbed/hidkbd: Added USB host support for the mbed LPC1768 board; add + a USB host HID keyboard configuraion. + * drivers/usbhost/hid_parser.c: Leverages the LUFA HID parser written by + Dean Camera. + * examples/nsh: Correct an usage of getopt(): If you stop calling getopt() + before all parameters are parsed, you can leave getopt() in a strange state. + * include/nuttx/video/fb.h: Restore missing RGB type that was accidentally removed + when Nokia 6100 support was added. + * Rename arch/pjrc-8051 to arch/8051 + * configs/ne64badge: Add a configuration for the Future Electronics Group + NE64 Badge development board (Freescale MC9S12NE64) + * Changes contributed by Uros Platise: + - Add support for the STM32F103RET6 + - configs/vsn: Support for the ISOTEL NetClamps VSN V1.2 ready2go sensor + network platform + * arch/hc, configs/ne64badge: Development is complete for the Freescale + mc9s12ne64 on the Future Electronics Group NE64 /PoE Badge board. Howeve, + this port remains untested until I figure out this BDM / Code Warrior + and paged build thing + * Added a new 'kill' command to NSH that will support sending signals to + running NuttX tasks. + +5.19 2011-03-12 Gregory Nutt + + * arch/arm/stm32/stm32_idle.c: During idle times, the STM32 now uses the + WFI instruction to sleep in a reduced power mode until the next interrupt + occurs (Contributed by Uros Platise). + * NSH: 'mem' command renamed to 'free'. Output is now more similar to the + Linux 'free' command. + * NSH: Correct a redirection bug in NSH. The following would not work; it + resulted in a hang after the 'cat /dev/fifo': + + nsh> mkfile /dev/fifo + nsh> cd /tmp # /tmp is a mounted RAM disk + nsh> cat /dev/fifo > test.txt & + nsh> echo "This is a test" > /dev/fifo + + The error was caused because (1) there was a path that resulted in stdout + being closed (the "hang") and also (2) the 'cat' command was always outputting + to stdout, not to the redirected file descriptor. Now: + + nsh> cat test.txt + This is a test + + * drivers/pipes/pipe_common.c: Driver open method was not returning an EINTR + error when it received a signal. Instead, it just re-started the wait. This + makes it impossible to kill a background pipe operation from NSH. + * include/stdint.h: Correct some errors in conditional compilation (submitted + by Johannes Hampel). + * arch/arm/lpc17xx/lpc17_idle.c: Uses the same logic as the STM32: uses the + WFI instruction to sleep in a reduced power mode until the next interrupt + occurs. + * configs/olimex-lpc1766stk: Added an LED encoded to indicate if the LPC1766 + is in sleeping. + * examples/mm: This is a simplified version of the "built-in" memory manager + test of mm/mm_test.c. It is simplified because it does not have access to + the internals of the memory manager as does mm/mm_test.c, but it has the + advantage that it runs in the actual NuttX tasking environment (the + mm/mm_test.c only runs in a PC simulation environment). + * drivers/mmcsd_sdio.c/h: Several corrections submitted by Uros Platise. + * arch/x86: Provide support for x86 architectures. Support for the i486 + architecture under QEMU is provided under arch/x86/include/i486, + arch/x86/include/qemu, arch/x86/src/i486, and arch/x86/src/qemu. + * configs/qemu-i486: "Board" support configurations for verifying the QEME + i486 port. + * arch/arm/src/stm32/stm32_spi.c: Correct base address of SPI3 (reported by + Uros Platise). + * drivers/mmcsd/mmcsd_sdio.c: Correct a loop termination condition (also + reported by Uros Platise). + * drivers/mtd/ramtron.c: Driver for SPI-based RAMTRON NVRAM devices FM25V10 + (and others). Contributed by Uros Platise. + * examples/nsh and tools/mkromfsimg.sh: Add support for platform-specific + ROMFS-based NSH start-up scripts. + * drivers/serial/uart_16550.c and include/nuttx/serial/uart_16550.h: Support + for a generic 16550 UART. + * configure/qemu-i486/nsh: QEMU NSH example. + * ../apps: The apps directory add-on was created by Uros Platise. It + supports a set of end-user applications than can be executed on top of + NSH. Think of it this way: In a buckled-up embedded application, your + end-user programs will probably have their own dedicated start-up logic. + But, during development, you might want to have you applications + available and executable from the NSH command line. This apps/ addon + (and NSH hooks) was contributed by Uros to accomplish just that. + * sched/sched_waitpid() and include/sys/wait.h: Provides a simple and + very incomplete implementation of waitpid(). waitpid() is only available + if CONFIG_SCHED_WAITPID is defined in your configuration file. + * sched/atexit.c and sched/exit.c: The atexit function is not frequently + used. In order to save a few bytes, it is now conditioned on + CONFIG_SCHED_ATEXIT. It your application is currently using atexit(), + you will need to add CONFIG_SCHED_ATEXIT to your configuration file. + * drivers/net/slip.c: Add a SLIP driver (untested on initial check-in). + * configs/olimex-lpc1766stk/slip-httpd: An example that uses SLIP to + provide a serial-port based THTTPD web server. + +6.0 2011-03-21 Gregory Nutt + + * lib/lib_fopen(): fopen() was not returning the correct errno value + when the underlying open() failed. + * include/net/uip/uip-arch.h: The uIP interface has been extended + slightly so that drivers can be concurrenly filling and sending + packet buffers. This capability was needed by the SLIP driver. + * drivers/net/slip.c: Several corrections and some re-design of + of the driver. + * apps/ChangeLog.txt: the apps/ directory now has its own ChangeLog. + * configs/vsn: + - IDLE LED blinking fix + - Added board power off function + * arch/arm/src/stm32/stm32_gpio.c and stm32_internal.h: Fixed + PullUp/Down Input Configuration. + * arch/arm/src/lpc17xx/lpc17_serial.h: Now supports Auto-RTS and + Auto-CTS modes. This is needed to support SLIP. + * drivers/net/slip.c: SLIP is now basically functional on the + LPC17xx with some caveats as described in the TODO list under + LPC17xx. + * arch/x86/include/i486/irq.h: Fix irqrestore() macro... it was not + correctly re-enabling interrupts. + * arch/x86/src: Fix numerous problems with i486/QEMU context + switching. Basically, the logic was missing the cases to handle + the differing stack frames when a priority change occurs and when + no priority change occurs. + * configs/qemu-i486/ostest and nsh: The QEMU i486 port is complete. + it now passes the OS test and supports the NuttShell (NSH). + * misc/drivers: Created a new directory to hold non-BSD licensed + drivers that may be added into NuttX via an installation script. + * drivers/usbhost/usbhost_rtl8187.c: A decision was made to + incorporate code taken from the Linux kernel. That changes the + licensing on this module to GPL. To avoid licensing contamination, + this driver was moved to misc/drivers/rtl8187x *prior* to adding + any of the GPL logic. There is an INSTALL.sh script at the location + where the GPL driver(s) can be re-installed into the NuttX source + tree. By re-installing the driver, you agree to the GPL licsensing + and all of its implications. + * Makefile, apps/Makefile, tools/configure.sh: Add logic to copy + configs///appdir to apps/.config and to simply the + application configuration logic. + * examples/nsh and apps/nshlib: Move the core NuttShell (NSH) logic + out of the exemples directory and into the apps/ directory where + it belongs. + * apps/Makefile and configs/*/appconfig: Use '=' as the delimiter + instead of '/' so that sub-directories in apps/ can be used. + * apps/vsn: Move all VSN apps to apps/vsn. + * nuttx/examples moved to apps/examples + +6.1 2011-04-11 Gregory Nutt + + * arch/arm/include/lpc17xx/irq.h and arch/arm/src/lpc17xx/lpc17_gpio*.c: + Fix several bugs in the GPIO interrupt logic. Submited by + Decio Renno. + * Initialization for the CONFIG_APPS_DIR is now supported during the + earlier, 'context' build phase. + * arch/arm/src/lpc17_gpioint.c: Finish coding of the LPC17xx GPIO + interrupt logic. + * net/netdev_unregister.c: Add capability to un-register a network + device. + * drivers/mmcsd/mmcsd_sdio.c: extra effort to correctly handle cases + without the SDcard (but one issue still exists in STM32) + * arch/arm/src/stm32/stm32_tim.*: Added basic timer support TIM1..TIM8 + with output PWMs and interrupt logic + * config/vsn/src: Added basic support for Sensor Interface (GPIO and + PWM Power Output, and the sif utility program) + * fs/: Reorgnize header so that file systems can be built outside + of the nuttx source tree + * apps/namedapp/binfs.c: Create a tiny filesystem that can be used + to show the internal named apps under /bin. + * fs/fs_opendir.c: Correct an error that occurs when a file system is + mounted in the root directory. This was discovered while mounting + the named app's /bin directory. + * lib/: Move all source files into a subdirectory of lib/ named after + the header file in which the library function is prototyped. + * sched/ and lib/pthread/: Move pthread attribute-related interfaces + from sched/ to lib/pthread where they more appropriately belong. + * sched/ and lib/semaphore/: Move some semaphore-related interfaces + from sched/ to lib/pthread where they more appropriately belong. + * syscall/: The beginnings of an optional syscall Kernel interface. + * tools/mksyscall.c: Add a tool that will auto-generate syscall proxies + and stubs from a comma-separated-value (CSV) data file. + * arch/arm/src/cortexm3/mpu.h: Add a header file describing the Cortex-M3 + MPU registers. + * Numerous modifications to the build system. Various people have reported + build problems since the re-organization and release of NuttX-6.0. I am + unable to replicate the build problems in my environment, but the changes + have be incorporated in hope of correcting the build issues in other + environments. + * drivers/i2c/st_lis331dl.c: I2C-based driver for the LIS331DL MEMS + motion sensor. Contributed by Uros Platise. + * Makefile: The NuttX build system will now supported building NuttX as two + separately linked images: (1) a kernel-mode RTOS image, and (2) a user- + mode application image that communicates to the RTOS kernel via system + calls. A lot more still must be done. + * user_initialize(): Eliminated the user_initialize() initialization hook. + It is difficult to maintain and redundant: Board level initialization + an up_initialize() provide the same kind of capability. + * arch/*/include/*/type.h: On some compilers, char defaults as unsigned. + Explicitly add signed to integer types if signed is what is required. + * arch/*: For all architectures -- Global register state save structure + (usually called g_current_regs) should be marked volatile; Added general + capability to support nested interrupts (not fully realized for all + architectures). + * sched/task_create.c: Add support for starting kernel-mode thread. + * drivers/usbdev/usbdev_serial.c: Fix reported by Sheref Younan. USB + was being reset after serial driver was closed. As a result, you could + no reopen the serial driver. + * configs/lpcxpresso-lpc1768: Add a board configuration for the Embedded + Artists LPCXpresso LPC1768 board. + +6.2 2011-05-06 Gregory Nutt + + * arch/arm/src/lpc17xx/lpc17_gpioint.c: Correct errors in logic that maps + and IRQ number into a register bit number. + * Makefile: Fix an error introduced in the top-level Makefile in NuttX-6.1. + This error only shows up if you have a /tftpboot directory. Then the + make will fail with an obscure error about not being able to stat pass2. + * configs/lpcxpresso-lpc1768/nsh: Add an NSH configuration for the + LPCXpresso board. + * configs/*/ld.script: Removed 'sh_link not set for section .ARM.edix' for + a few of the builds. In you have this warning, it can be removed with the + following change to the ld.script file: + + + __exidx_start = ABSOLUTE(.); + .ARM.exidx : { + - __exidx_start = ABSOLUTE(.); + *(.ARM.exidx*) + - __exidx_end = ABSOLUTE(.); + } >sram + + __exidx_end = ABSOLUTE(.); + + * arch/arm/src/lpc17xx: Correct some typos/bugs in configuration of LPC17xx + UART2 and UART3. + * nuttx/clock.h: Replace all references to the global variable g_system_timer + with clock_systemtimer() (currently just a macro that that returns g_system_timer). + * lib/string/strrch.c: Would fail if the searched-for character were the first + character in the string. + * tools/version.sh and mkversion.c: Tools to manage a NuttX version number + file + * sched/clock_getutc() and lib/time/lib_time.c: Add support for 1 second UTC + interface. + * net/net_dup2.c and include/nuttx/net.h: The conditional compilation for + '#if CONFIG_NFILE_DESCRIPTOR > 0' was wrong in both of these files. It should + be '#if CONFIG_NFILE_DESCRIPTORS > 0'. This causes a dup2() failure in THTTPD + and a failure to get a CGI page. The consequence can be a very serious bug! + * configs/lpcxpresso-lpc1768/usbstorage, thttpd, and dhcpd: Add an USB storage, + THTTPD web server, and DHCP server configurations for the NXP LPCXpresso board. + * drivers/lcd/ug-9664hswag01.c and ssd1305.h: Add support for Univision UG-9664HSWAG01 + OLED with Solomon Systech SD1305 LCD controller. + * configs/lpcxpresso-lpc1668/nx: Add a NX graphics configuration for the LPCXPRESO + board. + * graphics/nxglib/nxglib_nonintersecting.c: Fix some single bit errors in + calculation of non-intersecting regions. This was causing an anomaly + in examples/nx in column 0. + * drivers/mtd/rammtd.c: Added a RAM based MTD driver. This RAM driver simulates + FLASH and is useful for testing purposes. + * arch/arm/src/arm/up_head.S: Fix backward conditional compilation. This cause + the configs/mx1ads configuration to fail to build but does not appear to affect + any other ARM9 build. + * fs/nxffs: Adding a tiny, wear-leveling FLASH file system for NuttX. This + file system is intended to be small and will have some limitations. The + implementation is incomplete on initial checkin. + * apps/examples/nxffs and configs/sim/nxffs: Add a test a a configuration that + will be used to verify NXFFS. + * fs/fat/fs_fat32.c and fs_fat32util.c: Incorpated two bugs with fixed provided + by Sheref Younan. Thanks! + * fs/nxffs: After a couple of weeks of testing and bug fixes, NXFSS appears + stable and functional. + +6.3 2011-05-15 Gregory Nutt + + * Remove clock_getutc(). It is replaces with clock_gettime(CLOCK_ACTIVETIME). + Add other RTC related changes provided by Uros Platise. + * arch/arm/src/stm32/stm32_flash.c: Add support for access to on-chip STM32 + FLASH; beginning of integration with NXFFS (Uros Platise). + * arch/mips: Added directory structure for PIC32 support + * configs/pcblogic-pic32mx: Add directory structure for PCB Logic PIC32MX board + * apps/include: Move include/apps to apps/include. A symbolic link is created at + build time + * Makefile: Removed support for Pascal pcode interpreter. Support for that + interpreter has been moved to apps/interpreter/Makefile. + * tools/mkdep.sh: Should not report an error if there are no files on the command + line. This happens normally in certain configurations. + * drivers/usbhost: Sheref Younan reported an error in the error handling when + connection to a USB device fails. In certain fail cases, the logic would try + to free the device class instance twice, the first was okay, but the second + caused a crash. + * graphics/nxbe/nxbe_colormap.c: Fix error noted by Bassem Fahmy. The function + nxbe_colormap was change to nxbe_configure... apparently "search-and-replace" + error. This error was not noticed before because most NX platforms do not use + colormapping. + * arch/rgmp and configs/rgmp. Add architecture support and build + configuration for RGMP. RGMP is a project for running GPOS and + RTOS simultaneously on multi-processor platforms. See + http://rgmp.sourceforge.net/wiki/index.php/Main_Page for further + information about RGMP. + * lib/stdio/lib_fclose.c: Must flush all buffered data when the file is closed. + Instead, it was discarding the buffered data. + * lib/stdio: All output stream logic was modified to support CONFIG_STDIO_LINEBUFFER. + If standard C buffered I/O is enabled (CONFIG_STDIO_BUFFER_SIZE > 0), then this + option may be added to force automatic, line-oriented flushing the output buffer + for putc(), fputc(), putchar(), puts(), fputs(), printf(), fprintf(), and vfprintf(). + When a newline is encountered in the output string, the output buffer will be + flushed. This (slightly) increases the NuttX footprint but supports the kind of + behavior that people expect for printf. + +6.4 2011-06-06 Gregory Nutt + + * lib/drivers/cc1101: Add initial, functional CC1101 wireless driver + (contributed by Uros Platise) + * arch/mips and configs/pcblogic-pic32mx: The MicroChip PIC32MX port is now + code complete and ready to begin testing. Unfortunately, it looks like + testing will be delayed due to tool issues (My PICkit 2 will not work the + the MPLAB debugger on PIC32; I will need to get a PICkit 3). + * drivers/net/e1000.c/h: A PCI-based E1000 Ethernet driver submitted + by Yu Qiang. + * lib/net/lib_inetaddr.c: An implementation of the inet_addr() function + submitted by Yu Qiang. + * arch/arm/src/lpc31xx and arch/arm/include/lpc31xx: Renamed from lpc313x + to make name space for other famiy members. + * arch/arm/*/lpc31xx: Added support for the LPC315x family (untested). + * sched/task_exithook.c: Functionality performed when a task exits or is + deleted has been moved to a common file task_exithook.c. Now exit() + functionality (like flushing I/O and calling registered atexit() + functions, etc.) will be performed when a task is deleted as well. + * mm/: Added support for CONFIG_MM_SMALL. Each memory allocation has a + small allocation overhead. The size of that overhead is normally + determined by the "width" of the address support by the MCU. MCUs + that support 16-bit addressability have smaller overhead than devices + that support 32-bit addressability. However, there are many MCUs + that support 32-bit addressability *but* have internal SRAM of size + less than or equal to 64K. In this case, CONFIG_MM_SMALL can be + defined so that those MCUs will also benefit from the smaller, 16- + bit-based allocation overhead. + * lib/string/lib_strndup.c: Add standard strndup() library function. + * net/getsockname.c: Added standard getsockname() to return the local + address associated with a socket. + * lib/stdio/lib_asprintf.c: Add asprintf() + * configs/olimex-lpc1766stk/ftpc: Add a configuration to support + testing of the FTP client shell. + * fd/fs_fdopen.c and net/net_checksd.c: Add support so that fdopen may + be used with socket descriptors. + * net/recvfrom.c: Fix an error found in receiving small files via FTP: + The small file is received a buffered in the readahead buffer, then the + socket is disconnected. When the app calls recvfrom, the socket is + already disconnected and the buffered data is stranded. Now, recvfrom + will continue to return success after the socket is disconnected until + the readahead buffer is drained. + * olimex-lp1766stk/ftpc/defconfig: Many configurations have the MTU + (CONFIG_NET_BUFSIZE) set to very small numbers, less then the minimum + MTU size that must be supported -- 576. This can cause problems in + some networks: CONFIG_NET_BUFSIZE should be set to at least 576 in + all defconfig files. This has only been fixed in this defconfig file. + +6.5 2011-06-21 Gregory Nutt + + * arch/avr/src/avr and arch/avr/include/avr: Adds general support for + the Atmel 8-bit AVR family. + * arch/avr/src/atmega and arch/avr/include/atmega: Adds support for the + Atmel AVR ATMega family. + * arch/avr/src/at90usb and arch/avr/include/at90usb: Adds support for the + Atmel AVR AT90USB family. + * configs/micropendous3: Adds a board configuration for the Opendous + Micropendous 3 board. This board may be populated with several different + members of the Atmel AVR AT90USB family. + * configs/amber: This is a placehold for the Atmel ATMega128 Amber Web + Server from SoC Robotics. Not much present in this directory on initial + check-in. + * configs/teensy: Adds a board configuration for the PJRC Teensy++ 2.0 board + that features an Atmel AT90USB1286 MCU. + * fs/fat: Offsets, sector numbers, etc. need to be off_t, not size_t. size_t + is intended to be the maximum size of a memory object, not a file offset. This + does not make any difference except on systems (like the AVR) where size_t + is only 16-bits. + +6.6 2011-07-11 Gregory Nutt + + * drivers/mtd/ramtron.c, net/net_checksd.c, fs/fs_fdopen.c, and include/nuttx/mii.h: + Several structural changes made to get a clean compile under the eZ80 ZDS-II + toolchain (no design changes). + * drivers/usbhost/usbhost_storage.c: Incorpated bugfixes reported by Sheref H. + Younan: (1) Read capacity logic read largest block, not the number of blocks + and was, therefore, off by one, and (2) Some devices stall of get Max LUN request + if they support only a single LUN. Logic now assumes a single LUN if the get + Max LUN request fails. + * include/nuttx/arch.h, lib/stdio/lib_libvsprintf.c, lib/stdio/lib_fputs.c: Add + a new configuration option to support extracting strings from FLASH or EEPROM + or other memories where the string data cannot be accessed by simply de-referencing + a string pointer. + * arch/sim/src/up_romgetc.c: Used to test the basic logic to access strings + without directly de-referencing a string pointer. + * arch/avr/src/avr/up_romget.c: Used to access strings that lie in the first + 64K of FLASH (But I still haven't figured out how to get strings to reside in + FLASH without using the PROGMEM attribute). + * configs/teensy/src/up_spi.c: Correct reading of SD CD and WP pins (was reading + the wrong register. AVR SPI now appears to be functional. + * arch/avr/src/at90usb/at90usb_usbdev.c: Correct USB initialization. Interrupts + were being enabled BEFORE the interrupt handler was attached. + * configs/sure-pic32mx: Add a configuration for the Sure Electronics, "Advanced USB + Storage Demo Board," Model DB-DP11215 (http://www.sureelectronics.net/goods.php?id=1168). + This board features the MicroChip PIC32MX440F512H MCU. (Untested on initial + check-in). + * configs/stm3210e-eval/nsh2: Add another NSH configuration for the STM32 with + some different properties. + * CONFIG_NSH_CONDEV: Add a configuration option to allow using a different character + device (such a a different UART) for the NSH interface. This allows, for example, + debug output to come from the console device while using another device for NSH. + There are some issues on initial check-in: NuttX doesn't have termios and the + console device has special properties that make using NSH awkward. Examples: + No CR-LF expansion, no character echoing, no command line editting. + * arch/arm/src/stm32/stm32_lowputc.c and stm32_serial.c. Correct several bugs + involving serial port configuration. These bugs are only critical if you + are trying to using multiple UARTs on STM32. + * configs/stm3210e-eval/src/up_lcd.c: Add a driver for the STM3210E-EVAL's LCD. + * configs/stm3210e-eval/nx: Add NX configuration for the STM3210E-EVAL. + * configs/nuttx/arch.h (and arch/arm/src/stm32, configs/*/src/up_buttons.c): + Standardize interfaces exported for button support and button interrupts. + * configs/stm3210e-eval/src/up_buttons.c: Add interrupting button support. + Also fixes a few errors in STM3210E-EVAL button decoding. + * configs/stm3210e-eval/buttons: Add a configuration to exercise STM3210E-EVAL + buttons. + * arch/arm/src/stm32/stm32_gpio.c: GPIO interrupt handling for pin + numbers were being aliased: 5-9 together and 10-15 together. Extended + the logic to peform decoding of GPIO interrupts and unique dispatching + for all 16 pins. + * configs/stm3210e-eval/nxtext: Add a configuration for the apps/examples/nxtext + example. This example focuses on placing text on the background while + pop-up windows occur. Text should continue to update normally with or without + the popup windows present. + * arch/arm/src/common/up_checkstack.c: ARM stack overflow checking submitted + by Hal Glenn. + * arch/arm/src/lpc17xx: Changes to compile successfully with no serial console + (also submitted by Hal Glenn). + * graphics/nxfonts/nxfonts_convert.c: Fixed a critical bug that caused + when renderer some fonts with bits-per-pixel > 8 + * graphics/nxbe/nxbe_move.c: Fixed an error in the graphics move logic (This + was a previously untested interface). Basically, there is some confusion + between use of (x,y) as a relative offset or as an absolute position. + * graphics/nxbe/nxbe_close.c: Fixed an important graphics system bug: + When a window is closed, the display was not being updated. The old + window graphic was left on the display for a time. + +6.7 2011-08-02 Gregory Nutt + + * Makefile: Added a export target that will bundle up all of the NuttX + libraries, header files, and the startup object into an export-able + tarball. + * arch/arm/src/lpc17xx/lpc17_can.h: Correct some typos in the CAN + register definitions. + * drivers/serial/serialirq.c: Correct an error that can occur if the + serial RX buffer becomes full. Data is now discarded in that case; + before, leaving data in the hardware would cause infinite interrupts + one most MCUs since you must read the data in order to clear the + interrupt. + * arch/arm/src/lpc17xx/lpc17_can.c: Added a CAN driver contributed by + Li Zhuoyi (Lzyy). + * include/stddefs.h and sys/types: Added type wchar_t. + * fs/fat/fat_fat32dirent.c: Move all FAT directory operations to this + new file; Implement VFAT long file name support. + * fs/fat/fat_fat32dirent.c: The configuration CONFIG_FAT_LCNAMES has + been around for some time but never tested until now. This setting + will mimic the NT 8.3 file name behavior: File names or extensions + may be all upper or all lower case (but not mixed). If + CONFIG_FAT_LCNAMES is not selected, all filenames are strictly upper + case. + * configs/stm3210e-eval/nsh2: Console is back on UART1; Added + examples/nx as an NSH "built-in" command as a demonstration. + * fs/fat/fs_fat32dirent.c: Fix an important bug in the directory + allocation (fat_allocatedirentry()). I looks like it could be + initializing the wrong sectors! NOTE: This function was in + fs_fat32utils.c in earlier releases. + * arch/arm/src/stm32_sdio.c: Correct an important DMA-related bug; + SDIO transfer completion events and DMA completion eventes were + not being coordinated correctly. + * configs/stm3210e-eval/nsh2: Enable FAT long file name support + * sched/sem_timedwait.c: Add the standard sem_timedwait() interface. + * graphics/nxfonts/nxfonts_getfont.c, nxfonts_bitmap.c, + Makefile.source, and include/nuttx/nxfonts.h: Support for multiple + fonts included. A new interface, nxf_getfonthandle() takes a font + ID and returns a handle that is now used at all other font interfaces + to specify which of the multiple fonts to use. + * arch/arm/src/lpc17xx/lpc17_syscon.h: Fix typo (reported by Li Zhuoyi). + * configs/stm3210e-eval/nsh2: Extended to support two new commands: + 'msconn' will connect the USB mass storage device; 'msdis' will + disconnect the USB storage device. + * tools/bdf-converter.c. This C file is used to build the bdf-converter + program. The bdf-converter program be used to convert fonts in Bitmap + Distribution Format (BDF) into fonts that can be used in the NX graphics + system. + * include/nuttx/nx: Move all NX header files from include/nuttx to + include/nuttx/nx. + * drivers/usbdev/usbdev_usbstorage.c and arch/arm/src/stm32/stm32_usbdev.c: + Correct a memory leak when the USB mass storage driver is connected and + then disconnected from the target. The write requests were not being + freed. NOTE that the unregister logic in the STM32 needed to call + stm32_reset() in order to return the write requests to the USB mass + storage driver; it is possible that a similar but could exist for other + architectures. + * graphics/nxfonts/nxfonts_*.h: Add serveral more new fonts + * arch/z80/src/eZ80/ez80_serial.c: Fix some errors in serial driver + setup for UART1 (submitted by Paul Osmialowski). + * drivers/input/tsc2007.c and include/nuttx/input/*: Add a generic NuttX + touchscreen interface.

The driver now supports both CAN1 and CAN2. + * arch/arm/sim/up_lcd.c: Add a simulated LCD driver. + * configs/stm3210e-eval/nxlines: Added a configuration to build + examples/nxlines. + * arch/graphics: Used apps/examples/nxlines to (finally) verify the NX + trapezoid drawing functions and (wide) line drawing functions. + * arch/rgmp and configs/rgmp. Yu Qiang has ported RGMP to the OMAP4430 (arm) + pandaboard and release the new RGMP 0.3 version. The main changes are: (1) + Separate configs/rgmp/x86 and configs/rgmp/arm configuration directory, and + (2) Extract architecture dependent code in arch/rgmp/include and + arch/rgmp/src into corresponding x86/ and arm/ directories. + * arch/arm/src/kinetis, arch/arm/include/kinetis, configs/kwikstick-k40: + Add a directory structure to support the port to the Kinetis KwikStik-K40. + There is no real substance in the initial check-in; only the directory + structure and skeleton files (Code complete on 8/15/11). + * arch/arm/include/armv7-m, arch/arm/src/armv7-m, etc.: Rename all cortexm3 + directories and files to armv7-m; Change name of of all CORTEXM3 constants + to ARMV7M. This is a major namespace change needed to cleanly support the + ARM Cortex-M4 which is also in the ARMv7 M Series (specifically, ARMv7E-M). + * sched/sig_initialize.c, sig_received.c, and mq_waitirq.c. Fixed several + critical bugs related to signal handling initialization and for signals + the wake up tasks that are waiting to send or receive message queues. In + the first two files, errors would prevent proper allocation of signal-related + structures from interrupt handlers. In the second, there was missing + "clean-up" logic after a signal occurred, leaving the message queue in + a bad state and resulting in PANICs. All are important. (submitted by + hkwilton). + * arch/arm/src/kinetis: Added header files defining all Kinetis registers + and bit fields within all Kinetis registers. + * configs/twr-k60n512: Add support for the Kinetis K60 Tower board + (TWR-K60N512). + * drivers/can.c: Fixed a semaphore overflow problem in the CAN driver + (reported by Li Zhouy (Lzyy)). + * 8/18/2011: The basic port to the FreeScale Kinetis TWR-K60N512 board is + now functional. + * configs/twr-k60n512: Add Kinetis TWR-K60N512 NSH configuration. + * drivers/analog and include/nuttx/analog: Add ADC driver infrastructure + and TI ADS1255 driver developed and submitted by Li Zhouy (Lzyy)). + * arch/arm/stm32/stm32_sdio.h and drivers/mmcsd/mmcsd.c: Add logic to + multiplex usage of the GPIO pins (contributed by Uros Platise). + * configs/twr-k60n512/nsh: Added and verified a NuttShell (NSH) + configuration for the Freescale, Kinetis TWR-K60N512 board. + +6.9 2011-09-11 Gregory Nutt + + * arch/arm/src/kinetis/kinetis_sdhc.c: SDHC driver for Kinetis parts. + Initially check-in is just a crude port of the STM32 SDIO driver. + Much more work is needed. + * graphics/, include/nuttx/nx: Add new NX interfaces for drawing + circles -- both circular outlines and filled circles. + * graphic/nxglib/nxglib_spitline.c: Add a "fudge factor" that eliminates + some problems for rendering nearly horizontal, wide lines. Hmm... + but I suspect this fudge factor also leads to new problems rendering + very thin, nearly horizontal lines. More tuning is needed. + * drivers/analog, include/nuttx/analog, arch/arch/src/lpcxx: (1) Add + updates to the ADS1255 driver, (2) fix errors from my last merge (sorry), + (3) Add DAC infrastructure, (4) add AD5410 DAC driver, and (5) add + LPC17xx ADC and DAC drivers. All contributed by Li Zhuoyi (Lzyy). + * tools/mkexport.sh: Extended the script that implements the top-level + 'make export' logic. The script now also finds and bundles up all of + the architecture-specific header files as well. + * drivers/arch/arm/src/stm32/stm32_i2c.c: Add a reset to the I2C + initialization logic to prevent spurious interrupts when the I2C + interrupts are enabled (submitted by Uros Platise). + * Scripts/makefiles/documents. Several adjustments, corrections and + typo fixes so that NuttX will build correctly on FreeBSD using the + ASH shell (submitted by Kurt Lidl). + * drivers/mtd/flash_eraseall.c: Add a callable function that accepts + the path to a block driver and then erases the underlying FLASH memory + (assuming that the block driver is an MTD driver wrapped in the FTL + layer). Hmmm... this is probably not the best long term solution; + flash_eraseall() should be a user-callable function that operates + one driver interfaces; not an internal, OS function that operates + on directly on block drivers. + * drivers/bch: Fixed some important bugs in the BCH driver (noted by + Li Zhuoyi (Lzyy)). This would have effected any large reads or writes + (larger than the hardware sector size). + * arch/*/src/Makefile: Use of -print-libgcc-file-name to get path to + libgcc.a may select the wrong libgcc.a if a multilib toolchain (like + CodeSourcery) is used. This can be a serious problem and can cause + crashes on Cortex-M3 if the ARM libgcc is used, for example. The fix + is to include ARCHCPUFLAGS on the gcc command line when asking it to + -print-libgcc-file-name. + * lib/time/lib_gmtimer.c: Correct several calculations that could lead + to errors in dates. + * drivers/pm: Add the beginnings of a NuttX power management sub-system. + * arch/arm/src/stm32/stm32_irq.c: Fix a error introduced in 6.8. + Timeout calculation uses clock_settime() instead of clock_gettime(). + Pretty gross error, but actually it works with the side effect of setting + a bad time. + * drivers/mtd/at24xx.c: Driver for I2C-based at24cxx EEPROM submitted by + Li Zhuoyi (Lzyy). + * arch/arm/src/lpc17xx/lpc17_i2c.c: I2C driver for the NXP LPC17xx family + submitted by Li Zhuoyi (Lzyy) + * arch/arm/src/stm32_i2c.c: Correct two issues with the STM32 I2C driver: + (1) Clocking needs to be based on PCLK1, not HCLK and fast speed settings + need some additional bits; and (2) Correct a hang that will occur on + I2C1 if FSMC is also enabled. + * drivers/sensors/lm75.c and include/nuttx/sensors/lm75.h: Add an LM-75 + temperature sensor driver. + * configs/stm3210e-eval/src/up_lm75.c: Add support for the LM-75 on the + STMicro STM3210E-EVAL board. + * sched/clock_gettime.c: Correct an error in the tv_nsec calculation + that happens only config CONFIG_RTC is enabled. + * arch/arm/src/stm32/stm32_i2c.c: Correct some bugs related to waiting + for the I2C STOP condition to be cleared. + +6.10 2011-10-06 Gregory Nutt + + * lib/stdio/lib_fopen.c: Fix an error in fopen(); the file pointer was not + being positioned at the end of the file when the "a" and "a+" modes are + used. There are other issues with the "a+" modes (see the top-level TODO + list). + * drivers/usbdev/cdc_serial.c and include/nuttx/usb/cdc.h and cdc_serial.h: + Add support for the CDC ACM serial device class. + * fs/fat/fs_fat32.c: Fix a critical bug in the write logic: It a tiny write + cross a sector boundary, then two sector writes will occur. The first part + in the first sector may be written to the wrong sector number. + * fs/fat/fs_fat32util.c: Fix a stray write into the FAT (always sector 964 on + FAT32). This bug will cause some lost chains. I'm sure this bug could + corrupt files but at present, the only thing I have seen is that before + fixing this bug, the Windows chkdsk utility would report these lost chains. + * arch/arm/src/stm32/stm32_i2c.c: Driver can now operate in a faster polled + mode (at the expense of using more cpu cycles). + * arch/arm/src/stm32/stm32_i2c.c: Add trace debug capability. Enabled with + CONFIG_I2C_TRACE. + * arch/arm/src/stm32/stm32_i2c.c: Fix another bug where I2C conflicts with FSMC + being enabled. That time at the tail end of the transaction where there is + an unfinished stop condition. + * sched/mq_timedreceive.c and sched/mq_timedsend.c: The count of threads + waiting on the message queues was not being decremented after a timeout. + This would cause the accounting logic to become out of sync and the, perhaps, + an assertion to be triggered. This is an important bug and fixes a + potential crash when using mq_timedreceived() and mq_timedsend(). + * sched/mq_sndinternal.c: Related to the above, the send logic was incrementing + the wrong counter when it waited as part of the mq_timedsend.c logic. + * fs/fat: Fix an error in the long file name logic: If the long file name + is an even multiple of 13 bytes in length, then it should not include a + NULL terminating character. Fix contributed by Kaushal Parikh. + * configs/sim/nx11: Created a separate configuration to build the NX + example using the a simulated framebuffer driver on an X11 window. This + example has been verified on Ubuntu 9.09 (it does not work on Cygwin). + * arch/sim/src/up_touchscreen.c and up_x11eventloop.c: Adds support for a + simulated NuttX touchscreen device using mouse/pointer feedback from an + x11 window. + * configs/sim/touchscreen: Adds a configuration to verify the simulated + touchscreen driver (Does not work on Cygwin). + * configs/sam3u/touchscreen: This is the configuration that I plan to use + to verify the SAM3U-EK touchscreen driver. However, as of this writing, + there is no touchscreen driver for the board. + * CONFIG_RTC_HIRES: Add an option to support either a high-resolution RTC + that completely replaces the system timer tick but may overflow and lose + time when the MCU is off and also for a low-resolution (1 sec/tick) RTC + that can run until 2106 with no overflow. But in this latter case, higher + resolution time must come from the system timer. + * CONFIG_SYSTEM_UTC: Removed support for the UTC system timer. It just + doesn't do enough to be worth the CPU cycles or the complexity. + * CONFIG_SYSTEM_TIME16: Added support for an optional 64-bit system timer. + * fs/fat/fs_fat32util.c: Add support for FAT date/time stamps; Enabled via + CONFIG_FS_FATTIME. + * arch/arm/src/sam3u/sam3u_spi.c: Add an SPI driver for the AT91SAM3U. + * drivers/input/ads7843e.c and include/nuttx/input/ads7843e.h: Add a + driver for the TI ADS7843E touchscreen controller. + * fs/nxffs/nxffs_open.c: Fix an error when a file is open for writing; since + the file will get deleted it is already exists, there must be a check if + there are other open references to the file. + * arch/arm/src/stm32/stm32_sdio.c: Fixed an error where during SDHC + initialization interrupts were not being re-enabled. Caused more subtle + errors than you would think. + * arch/arm/src/stm32/stm32_i2c.c: Fixed an error where I2C timeouts appeared + to be successful transfers. + * configs/sim/nsh2: Add another simulated NSH configuration. This one + supports X11 graphics, C++, and exercises graphic functions as built-in + commands. + +6.11 2011-11-12 Gregory Nutt + + * arch/arm/stm32/Make.defs: Don't build stm32_rtc.c if CONFIG_RTC is not + selected. Doing so will cause errors if other configuration dependencies + are not met. + * configs/stm3210e-eval/src/up_lcd.c: Color corrections for SPFD5408B LCD + do not work with R61580 LCD. + * configs/pic32-starterkit: Beginning of a configuration for the Microchip + PIC32 Ethernet Starter Kit. Hmmm.. I don't have a clue how to test this + with no serial port?! + * lib/stdio/lib_fclose.c: fclose() always returns an error (EOF) when it + closes a read-only file. This is because it calls flush() which will + fail on read-only files. No harm is done other that a bad value is + returned. + * arch/sim/src/Makefile: Correct build issue for sim/nsh2 target. Old + libboard.a was not being cleaned. + * arch/mips/src/pic32mx/pic32mx-gpio*.c: Add GPIO support for the PIC32MX. + * configs/sure-pic32mx/src/up_leds.c and up_buttons.c: Add button and LED + support for the Sure Electronics PIC32MX board. + * configs/ea3152: Add a configuration for the Embedded Artists LPC3152 + daughter board (with the same base-board used with configs/ea3131) + * graphics/nxmu/nx_getrectangle.c, graphics/nxsu/nx_getrectangle.c, + graphics/mxtk/nx_getwindow.c, graphics/nxmu/nx_gettoobar.c: New + interfaces to read from graphics memory + * graphics/nxbe/nxbe_bitmap.c: Fix an error in the error handling that + can cause valid bitmaps to fail to render. + * include/nuttx/video/rgbcolors.h: Fix errors in some 16- and 8-bit color + conversion macros. + * tools/incdir.sh: Fix issues when g++ is used as the compiler. It was + not being recognized and handled properly. + * graphics/nxsu/nx_releasebkgd.c: Fix a bad cast that was causing + problems with the background window was released. + * fs/nxffs/nxffs_pack.c: Correct a critical bug in the NXFFS file system: + When repacking the filesystem, there was a missing check to see if an + inode structure would fit at the end of a block. This is a rare case + if the block size is large, but can be common for tiny block sizes + and results in a crash and file system corruption. + * fs/nxffs/nxffs_initialize.c: Fix an initialize error. If the FLASH + is full on power-up, NXFFS will fail to initialize correctly. + * fs/nxffs/nxffs_write.c and nxffs_pack.c: Fix an error that can occur + when attempt to write to FLASH volume that is completely full but + has no value inodes on it. + * drivers/mtd/at24xx.c: Now supports a configurable block size that + supports using "clusters" of AT24 pages as blocks. This allows bigger + block sizes and more efficient use of EEPROM when the AT24 is used to + support a file system (such as NXFFS). (Contributed by Hal Glenn). + * include/nuttx/video/rgbcolors.h: More fixes to RGB color conversion + macros. + * arch/arm/src/common/up_createstack.c and up_usestack.c: For ARM EABI + the stack must be aligned to 8-byte boundaries. This is necessary for + passing aligned floating point values under EABI. Fix contributed by + David Sidrane. + * Numerous changes and fixes to the PIC32 interrupt handing logic. The + PIC32 port is almost complete but still not ready for prime time. + +6.12 2011-12-06 Gregory Nutt + + * fs/fat/fs_fat32util.c and fs_fat32.h: Logic extended to look in up to + four partitions for a valid FAT file system. + * drivers/input/tsc2007.c: Add support for 8-bit conversions; make sure + that A/D converters are active before requesting conversions. + * drivers/mmcsd0/mmcsd_sdio.c: Increase capacity variable from size_t + to uin64_t (if available) so that SD cards with capacities greater + than 4Gb can be supported. + * fs/fat/fs_fat32dirent.c: The root directory structure is different + from other directories. When formatted by Windows, it is not initialized + at all. Some additional special handling is required to initialize the + root directory entry to interoperate correctly with windows. + * fs/fat/fs_fat32util.c: In fat_systime2fattime(void) should be + clock_gettime() and not clock_gettime(). Also, there is a place where + FAT date is used instead of FAT time. (Thanks to David Sidrane). + * arch/arm/src/stm32 and arch/arm/include/stm32: Add support for the + STM32F40xxx family of MCUs. + * configs/stm3240g-eval: Add framework for the STMicro STM3240G-EVAL + board. + * include/sys/types.h: wchar_t is a builtin type in C++ and its + declaration can cause errors with certain C++ compilers. + * sched/sig_timedwait.c: Fix signal handling when the returned info + is NULL.

This is a *critical* bug fix! + * net/uip/uip_tcpinput.c: Correct an error in the TCP stack. It was + incrementing the received sequence number BEFORE determining if the + incoming data could be handled. If the data was dropped (usually because + there is insufficient buffering space), then no ACK will be sent and the + sequence number will be wrong. The end consequence of the bad sequence + number was that the when the dropped packet was re-transmitted, it was + was ignored because its sequence number looked wrong.

(2) Fix handling of touch ID and (2) add some logic to + prevent certain kinds of data overrun. + * include/nx/nxtk.h and graphics/nx/nxtk/nxtk.h: Move setting + of configuration defaults from the internal header file to a place where + other logic can use the defaults. + * graphics/nxtk/nxtk_events.c: Fixed an important but in the logic that + translates the mouse/touchscreen position data for framed windows and toolbars. + * drivers/input/stmpe811_tsc.c, tsc2007.c, and ads7843e.c: Need to keep track of + when if positional data is valid. When the touch is released, the X/Y position + of the release must be the same as the X/Y position of the last touch (se that + the release occurs in the same window as the last touch). + * graphics/nxtk/nxtk_events.c: Fix an error in mouse/touchscreen input logic: + Was autoraising the window AFTER processing the mouse press. This raises havoc + if the result of processing the mouse click was to raise some other window! + * graphics/nxtk/nxtk_events.c: I had to disable the whole autoraise feature + for multi-user case because it does not work correctly. In a scenario where (1) there + are multiple queued touchscreen events for the same window and (2) the result of the + first input was to switch windows, then the autoraise implementation will cause the + window to revert to the previous window. Not good behavior. + * sched/sched_mergepending.c: Add task switching instrumentation. There is a case + here where instrumentation was missing. Contributed by Petri Tanskanen. + * CONFIG_STMPE811_THRESHX, CONFIG_STMPE811_THRESHX, and drivers/stmpe811_tsc.c: Add some + thresholding controls to all slow down processing of touchscreen samples. + This is a problem with NX in multi-user mode: touchscreen data gets sent + via a message and when the message queue gets full the sender blocks and + touch events are lost. Basic data overrun. The badly effects touchscreen + human factors. + * include/sched.h: Fix a typo (missing semicolon) in prototype of on_exit(); + * sched/on_exit.c and include/nuttx/sched.h: Fix some old typos that caused + compilation errors when CONFIG_SCHED_ONEXIT is defined. + * configs/stm3240g-eval/nxwm/defconfig: The default NxWM now uses the STMPE811 + touchscreen. + * include/cxx/csched: Added + * graphic/nxmu/nxmu_sendserver.c, nxmu_sendwindow.c, and nxmu_sendclient.c: + Refactor NX messaging logic in preparation for a new message control + feature. + * graphics/nxtk, graphics/nxmu, include/nuttx/nx: Add a new window communication + to support blocking and flushing of client window messages. If there are + stale, queue window messages at the time that a window is destroyed, very bad + things happen. + +6.19 2012-06-15 Gregory Nutt + + * graphics/nxconsole/nxcon_kbdin.c: If selected, the NxConsole will take + input from the NX keyboard input callback. If this option is set, then + the interface nxcon_kdbin() is enabled. That interface may be driven by + window callback functions so that keyboard input *only* goes to the top + window. If CONFIG_NXCONSOLE_NXKBDIN is not selected, then the NxConsole + will receive its input from stdin (/dev/console). This works great but + cannot be shared between different windows. Chaos will ensue if you + try to support multiple NxConsole windows without CONFIG_NXCONSOLE_NXKBDIN + * graphics/nxmu/nx_kbdin.c: Fix pointer argument. This is a error + introduced in changes leading up to the 6.18 release. This error will + cause crashes or perhaps simply not work when you try to handle window + keyboard data in multi-user mode. + * graphics/nxconsole/nxcon_kdbind.c: Fixed unmatched sem_wait and sem_post. + Fix some conditional compilation that included a few too many lines of code. + * drivers/input/stmpe811_tsc.c and stmpe811.h: Add a timeout to catch missed + pen up events. Now the STM3240G-EVAL touchscreen works very smoothly. + * configs/stm3240g-eval/nxwm/defconfig: Enable support for NxConsole keyboard + input. Increasing spacing of icons. + * configs/stm3240g-eval/nxwm/defconfig: Use a larger font for the calculator. + * include/nuttx/lcd/ssd1289.h, drivers/lcd/ssd1289.c and .h: Generic LCD + driver for LCDs based on the Solomon Systech SSD1289 LCD driver. This + of this as a template for an LCD driver that will have to be cusomized + for your particular LCD hardware. + * configs/stm32f4discovery/src/up_extmem.c and up_ssd1289.c: Add support to + STM32F4Discovery for than an external, SSD1289-based LCD. + * configs/stm32f4discovery/nxlines: Add an STM32F4Discovery configuration + to thest the SSD1289-based LCD. + * configs/stm3240g-eval/src: Add USB GPIO initialization logic needed + in board-specific boot logic. + * configs/stm32f4discovery/src: Add USB GPIO initialization logic needed + in board-specific boot logic. + * drivers/usbdev/pl2303.c and cdcacm.c: Fix the request size used for sending + packets. It was not using the maximum request size, but instead the previous + request size. As a result, packets get smaller, and smaller, and ... This + is an important USB serial fix. + * arch/arc/src/stm32_otgfsdev.c: Bug fix: Don't process TXFE if we have + already processed an XFRC interrupt. We have already done what needs + to done in that case. + * arch/arc/src/stm32_otgfsdev.c: Fixed some status settings in queuing of write + messages. Added a "hack" to work around missing TxFIFO empty interrupts. The + hack is basically to poll for space in the TxFIFO instead of of setting up + the interrupt. + * arch/arm/src/stm32/stm32f2* and chip/stm32f2*: Update all STM32 F2 file so + that they are equivalent to F4 files. This is kind of a maintenance nightmare. + * configs/stm3220g-eval/: Update existing configurations to the same level + as the corresponding STM3240G-EVAL configurations. This adds FSMC SRAM, + touchscreen, and LCD support. + * configs/stm3220g-eval/: Add a NxWM configuration for the STM3220G-EVAL. + * stmpe11*: Fix a massive naming problem. All references to STMPE11 should be + STMPE812. + * arch/arm/src/stm32/stm32_otgfsdev.c: Need to enabled USB reset interrupt + (contributed by Erik Van Der Zalm). + * sched/sleep.c: Fix the return value from sleep(). The correct behavior is + to return the number of unwaited seconds; the implementation was always + returning zero. + * sched/usleep.c and include/unistd.h: Was a void function, but should return + 0 on success. usleep() needs to check the return value from sigtimedwait(). + sigtimewait() returns the signal number that awakened it and an error (EAGAIN) + if the timeout expired (normal case). + * sched/sig_timedwait.c: Fix sigtimedwait() return value. On a timeout, it was + setting the 8-bit si_signo field to -1 and eded up reported successfully awakened + by signal 255! Now detects the timeout and errors -1 with errno == EGAIN. If + sigtimedwait() is awakened by an unblocked signal, but it is not one of the + signals in the waited-for set, it will return -1 with errno == EINTR. + * arch/arm/src/stm32_i2c.c: Fix STM32 F2 I2C. It is apparently bug-for-bug + compatible with the F4 and needs the same work-around for the missing BTF + signal that was needed for the F4. + * drivers/lcd/ssd1289.*: Fix some of the initial register settings. + * configs/stm32f4discovery/src/up_ssd1289.c: FSMC address bit 16 is used to + distinguish command and data. But FSMC address bits 0-24 correspond to ARM + address bits 1-25, se we need to set bit 17 in order generate output on + FSMC_A16. + * arch/arm/src/lm3s/lm3s_epi.h and lm3s_timer.h: LM3S header files + (contributed by Max Neklyudov). + * arch/arm/src/stm32/stm32_irq.c: Some of the interrupt priorities were + not be initialized (F2 and F4 only). Thus, the very high numbered + interrupts (like UART6) and cause nested interrupts. This leads to + some very difficult to debug crashes. Fix contributed by Mike Smith. + * arch/mips/src/pic32/pic32_head.S and pic32_config.h and + configs/pic32mx7mmb/include/board.h: Extended PIC32 device configuration + capabilities and change board.h to support unique clocking requirements + of the Mikroelektronika PIC32MX7 MMB. That board now works! + * configs/pic32mx7mmb/nsh: Added and verify a NuttShell configuration + for the Mikroelektronika PIC32MX7 MMB board. + * arch/mips/pic32/pic32mx-ethernet.c: Fix logic that guesses PHY address; + the search loop missed the PHY address needed by the Mikroelektronika + PIC32MX7 MMB board. + * configs/pic32mx7mmb/nsh: Configuration now supports a network by default. + * configs/pic32mx7mmb/src: Add support for the MMC/SD slot on board + the Mikroelektronika PIC32MX7 MMB board (not working on initial check-in). + * arch/mips/src/pic32/pic32mx-spi.c: Add support for very low-level, + register access debug output. + * configs//pic32mx7mmb/include/board.h: Reduced peripheral clock to + 4MHz to match other PIC32 configurations. + * configs/pic32mx7mmb/src/up_nsh.c: SD card needs to operate in SPI + mode 2. + * configs/pic32mx7mmb/nsh/defconfig: MMC/SD card support is now + enabled by default in the PIC32MX7 MMB board configuration. + * configs/pic32mx7mmb/nsh/defconfig: Verified the USB Mass Storage + Class (MSC) using MMC/SD card as the logical unit. Updated the default + PIC32MX7 MMB board configuration so that USB and the mass storage class + are enabled by default. + * drivers/lcd/mio283qt2.c and include/nuttx/lcd/mio283qt2.h: Add generic + support for the MIO283QT2 LCD. + * configs/pic32mx7mmb/src/up_mio283qt2.c: Add support for the MIO283QT2 + LCD on the PIC32MX7 MMB board. + * configs/pic32mx7mmb/src/up_touchscreen.c: Add an ADC-based touchscreen + driver for the PIC32MX7 MMB board. Kind of works, but needs more + verification and tuning. + * arch/mips/src/common/up_idle.c: Strange but important fix. For some still- + unknown reason, interrupts are left in an unhealthy state in the IDLE + when the work queue is enabled. This is partially because some interrupt + related logic is not built in that case. Simply disabling then re- + enabling interrupts restores the proper state. + * graphics/nxglib/lcd/nxglib_filltrapezoid.c and fb/nxglib_filltrapezoid.c: + Fix an error when the trapezoid is only 1 line high. In this case, a + divide by zero error would occur. The fix is to draw the 1 line high + trapezoid as a run. + * drivers/usbdev/pl2303.c: Fix a cut'n'paste error that snuck into + the PL2303 emulation driver several months back. + +6.20 2012-07-12 Gregory Nutt + + * configs/stm3210e-eval/src and arch/arm/src/stm32/: Add beginnings of + power management support for the STM32 and the STM3210E-EVAL board, in + particular. + * Documentation/NfsHowTo.html: Add a How-To document for the new NFS + client feature. + * arch/mips/include/pic32mx and arch/mips/src/pic32mx: Add support for the + PIC32MX1 and PIC32MX2 families. + * configs/mirtoo: Add a board configuration to support the DTX1-4000L + "Mirtoo" module from http://www.dimitech.com/ + * tools/pic32mx: All of the duplicate directories containing the same + same PIC32 tools were move to this single location. + * configs/mirtoo: The basic Mirtoo port is now functional. + * configs/mirtoo/ostest: Added support for the microchipOpen toolchain + (see http://sourceforge.net/projects/microchipopen/). + * configs/mirtoo/nsh: Added a NuttShell (NSH) configuration for + the Mirtoo module. + * configs/mirtoo/scripts: Move all Mirtoo linker scripts to a common + directory. + * arch/mips/src/pic32mx/pic32mx-gpio.c: All digital inputs were being + configured as outputs. This is a *critical* bug fix and needs to be + incorporated by any PIC32 users. + * drivers/mtd/sst25.c: Added a driver for the SST 25 SPI-based FLASH + parts. + * configs/mirtoo/src/up_nsh.c: The Mirtoo NSH configuration can now + mount the SST 25 devices so that it can be used for a FAT file system. + There are are, however, some NSH memory usage issues if this configuration + enabled now. Some tuning is still needed. + * configs/mirtoo/nxffs: Add an alternative NSH configure for the Mirtoo + module for testing the on-module SST 25 chip using the NXFFS file system. + * arch/arm/src/lpc43xx and arch/arm/include/lpc43xx: The NXP LPC43xx port + is slowly evolving in these directories. + * configs/stm3210e-eval/pm: Add a new configuration for testing STM32 power + management. + * configs/stm3210e-eval/scripts: Moved all of the duplicate ST3210-EVAL + linker scripts into one set of linker scripts at this location. + * configs/stm3210e-eval/src/up_buttons.c, up_lcd.c, and up_pm.c: New logic + for testing STM32 power management. + * configs/lincoln60: Add a configuration to support the Micromint Lincoln60 + board. + * configs/ekk-lm3s3b96: Add a configuration to support the TI/Stellaris + EKK-LM3S3B96 development board. Contributed by Jose Pablo Rojas V. + * arch/arm/src/lpc43xx/chip: Created header files for *all* (really) + lpc43xx registers and all bit-fields. + * configs/lpc4330-xplorer: Added a configuration for the NXP LPC43XX + Xplorer board. This is just to facilitate testing of the LPC43xx + port but will, with any luck, become proper board support for that + board. + * arch/arm/src/lm3s/lm3s_syscontrol.c: Fix an optimization related problem + by adding a volatile qualifier to a timing loop. Oddly, the consequence + of the bug is that when debug was off, the LM3S platform too a long time + to boot. It now boots rapidly whether debug is on or off. + * arch/*/include/limits.h: Change all values in all limits.h for all + architectures to signed decimal; the hex values were not sign extending + appropriate in most uses (reported by Lorenz Meier). + * arch/arm/src/stm32/chip/stm32f103/7vc_pinmap: Fix typographical error in + two pinmap definition files. + * lib/net/lib_inetntoa.c: Fix typographical error that cause compilation + failure on platforms that do not support passing of structures as + parameters. + * arch/arm/*/lpc43xx and configs/lpc4330-xplorer and code complete and + ready for testing. Hopefully, verified LPC43xx support will appear + in NuttX-6.20. + * include/nuttx/stdarg.h: If CONFIG_ARCH_STDARG_H=y is defined, the top-level + makefile will copy the generic (GCC-only) stdarg.h header file from + include/nuttx/stdarg.h to include/stdarg.h. So for the architectures + that cannot use their GCC toolchain's stdarg.h file, they can use this + alternative by defining CONFIG_ARCH_STDARG_H=y. If CONFIG_ARCH_STDARG_H, + is not defined, then the redirecting stdarg.h header file will stay + out-of-the-way in include/nuttx/. + * configs/lpc4330-xplorer/nsh: Add an NSH configuration for the LPC4330 + Xplorer board. + +6.21 2012-08-25 Gregory Nutt + + * configs/lpc4330-xplorer/up_nsh.c: Add support for a basic SPIFI block + driver for use by NSH. Does not work! Crashes on first SPIFI write. + * configs/lpc4330-xplorer/*/defconfig: Calibrate delay loops (this is + based on the current "slow" 72MHz M4 clock and will need to be + re-calibrated when this is increased). + * configs/stm3220g-eval/include/board.h and configs/stm3240g-eval/include/board.h: + The SDIOCLK frequency in the F2 and F4 derives for PLL48CLK and not HCLK + so that the SDIOCLK input frequency should always be 48MHz. + * sched/os_internal.h, sched_setupidlefiles.c, sched_setuptaskfiles.c, and + sched_setupidlefiles.c: Detangle some conditional compilation. Allow for + a perverse configuration that has socket descriptors and streams but no file + descriptors (sure, why not?). + * sched/: Stylistic clean-up of all files. Some of these files are pretty old + and do not follow current NuttX coding standards in detail. + * fs/: More stylistic file clean-up. + * mm/: More stylistic file clean-up. + * drivers/ and drivers/serial/: More stylistic file clean-up. + * arch/arm/src/lpc43xx/lpc43_clockconfig.c: Fix PLL1 bit manipulation logic. + Critical bugfix! This would often cause the LPC43xx to fail to boot. + * arch/arm/src/lpc43xx/lpc43_rgu.c: The soft reset logic called from the + beginning of __start seems cause problems. A magic delay seems to improve + the logic some. But I suspect that real fix is to get rid of all of the + soft reset logic. This would also be a critical bugfix if I believed + that it really fixed all of the issues. + * arch/arm/src/lpc43xx/chip/lpc43_cgu.h: Fix a bit mask in the PLL1 + control register. Critical bugfix. + * arch/arm/src/lpc43xx/lpc43_clockconfig.c and configs/lpc4330-xplorer/include/board.h: + Implement PLL1 ramp-up logic; Now the LPC43xx is running at 204MHz. + * configs/lpc4330-xplorer/*/defconfig: Re-calibrated delay loops using + the 204MHz clock. The LPC43xx ripping rips! This calibration was performed + with symbols enabled and all optimization disabled. It will need to be + better recalibrated again down the road. + * arch/arm/src/stm32/stm32_exti.c: Renamed to rch/arm/src/stm32/stm32_exti_gpio.c + to make a little room in the file name space. + * arch/arm/src/stm32/stm32_exti_alarm.c: Add initial logic to attached the + RTC alarm EXTI interrupt. This is work be performed mostly by Diego Sanchez. + * include/: More stylistic file clean-up. + * arch/arm/src/lpc43xx/lpc43_spifi.c, lpc43_spifi.h, and chip/lpc43_spifi.h: Add + logic to configure and initialize the SPIFI device (does not yet work). + * configs/lpc4330-xplorer/include/board.h: Reduce SPI SCLK value. + * arch/arm/src/lpc43xx/lpc43_spifi.c, lpc43_spifi.h, and chip/lpc43_spifi.h: + Logic completely redesigned. It now creates an MTD driver to access SPIFI... + but the driver still does not work. + * arch/arm/src/stm32 and arch/arm/include/stm32: Make name of RTC ALARM interrupt + common on STM32 F1,2,4 + * arch/arm/src/stm32 and arch/arm/include/stm32: Add support for the + STM32F100x "Value Line" devices. This includes changes to stm32F10xx_rcc.c that + add the ability to run the chip off the internal oscillator. There is no open + board configuration for this part yet (the STM32VLDiscovery would be a candidate). + Contributed by Mike Smith. + * arch/arm/src/stm32: Fixed typos in conditional compilation in the CAN and DMA + and some pin configuration. This would have caused problems for STM32 F107xx. + Typos noted by Mike Smith. + * arch/arm/src/lpc43xx/lpc43_serial.c: Add support for certain RS-485 features + * lib/termios/lib_cfsetispeed.c, lib_cfsetospeed.c, lib_tcflush.c: Add + simple implementations of cfsetispeed(), cfsetospeed(), and tcflush(). + * include/sys/str_tty.h, lib/lib_setspeed.c, lib_getspeed.c, and lib_resetspeed.c: + Add APIs to support setting non-standard BAUD values not supported by POSIX + termios. These are non-standard interfaces but have a precedence: There are + similar interfaces in AIX. + * include/sys/str_tty.h, lib/lib_setspeed.c, lib_getspeed.c, and lib_resetspeed.c: + Sigh... removed. We don't need any more almost standard interfaces! (SVN + revision 4968 if you want the short-lived code). + * include/termios.h and lib/termios/*: Open the existing, standard termios + interfaces to permit some non-standard baud settings. The new termios definitions + still supports the POSIX standard except that it does not strictly enforce + baud rate settings, permitting some non-portable, but useful baud rate settings + (this is what the short-lived AIX-like interfaces would have accomplished as well). + * include/termios.h and lib/termios/*: Redesigned yet again (this is getting + painful. NuttX now supports the BOTHER baud setting just as Linux does. termios + Bxxx definitions are again encoded; cf[set|get][o|i]speed now deal with only the + encoded values. If the encoded baud is set to BOTHER, then the values in the (non- + standard) c_ispeed and c_ospeed baud values may be accessed directly. + * arch/arm/src/stm32/stm32_serial.c: Add minimal termios support for the STM32 + (BOTHER style baud settings only).

The driver is specific to the C155 + because it uses the uwire transport. Contributed by Denis Carilki and + Alan Carvalho de Assis. + * drivers/power/pm_changestate.c. Correct a case where interrupts were not + being re-enabled. Found by Diego Sanchez. + * configs/mirtoo/nxffs/defconfig: This Mirtoo NXFFS configuration now uses the + open Pinguino toolchain by default. This is necessary because the free C32 + toolchain does not support any optimization and the unoptimized NXFFS image + hits the PIC32MX2 FLASH size (128K). There is plenty of room to grow using + the Pinguino toolchain with -O2 optimization. + * configs/mirtoo/src/up_adc.c.

Especially after realizing that + the syslog logic is going to have to some internal FS operations in order + to realize a totally thread-independent SYSLOG interface. + * arch/arm/src/stm32/stm32*_rcc.c and .h: If CONFIG_PM is defined, add a + function called stm32_clockenable() that can be used by PM logic to re-start + the PLL after re-awakening from deep sleep modes. + * fs/fs_foreachinode.c and fs/fs_foreachmountpoint.c: Add logic to traverse + inodes and mountpoints in the NuttX pseudo-file system. + * fs/fat/fs_fat32.c: Max. filename length reported by statfs() was wrong + if FAT long file names were enabled. + * lib/stdio/lib_libvsprintf.c: Fieldwidth and justification were not + supported for the %s format. As a result, %s, %12s, and %-12s all + produced the same output. + * lib/stdio/lib_libdtoa.c: Fix several issues with presenting floating + point numbers (conversions are fine, but presentation was bad).

The initial check-in, + however, is simply for the LPC31xx driver with name changes. The + LPC31xx has the same USB IP, but will require some additional initialization + (and lots of testing) before it can be used with the LPC43xx. + * nuttx/Documentation/NuttShell.html: Added a section covering ways to + customize the behavior of NSH. + * arch/arm/src/stm32/chip/stm32f1*_pinmap.h: STM32 CAN TX/RX pins reversed; + inconsistent conditional compilation.

Apparently 24 MHz is too fast for the board. + This (plus the change to the STM32 DMA (above) fixes SDIO DMA on the + STM3240G-EVAL (and probably STM3220G-EVAL -- untested). + * arch/arm/src/stm32/stm32f2xx_dma.c and stm32f4xx_dma.c: Backed out the + DMA priority change just above. The reduced SD card frequency was + necessary and sufficient to resolve the problem. + * drivers/serial/serial.c: open, read, write, and poll methods may now + abort return EINTR (or a short transfer size) if a signal is received + while waiting to receive or send serial data.

How did this compile before? (found by Kate) + * syscall/syscall.csv: Fix prototype for usleep() and prctl() (also + from Kate). + * arch/arm/src/lpc17xx/lpc17_ethernet.c: Conditionally elide setting PHY + speed/duplex. This does not work for certain PHYs. Still some unresolved + issues (also from Kate). + * tools/Config.mk, Makefile, configs/*/Make.defs: Add a new Makefile + fragment to de-quote certain strings from the Kconfig logic that + need to be used at path segments (Richard Cochran). + * arch/arm/src/stm32/stm32_usbotghost.c: The STM32 USB host driver only + works with debug turned on. The problem appears to be that with debug + OFF, there are more NAKs occuring in more places than before and this + reveals a variety of errors. This check in improves NAK robustness + for control transfers but does not resolve all of the issues. + * configs/stm3220g-eval/*/defconfig: Calibrated delay loop. It had + never been calibrated was way off. + * sched/sem_holder.c: Add logic to handler some priority inheritance + cases when sem_post() is called from an interrupt handler. The + logic is clearly wrong, but it is not known if this is the + cause of any known bugs. + * lib/stdio/lib_perror(): Add perror(). Contributed by Kate. + * lib/string/lib_strerror(): Add option CONFIG_LIBC_STRERROR that + is now required to enabled strerror(). Add an option + CONFIG_LIBC_STRERROR_SHORT that can be used to output shortened + strings by strerror(). + * arch/arm/src/stm32/stm32_usbotghost.c: Finally... the USB OTG FS + appears to handle NAKing correctly. + * configs/stm32f4discovery/*: Added and verifed support for USB OTG FS + host on the STM32F4Discovery board. + * configs/*/defconfig: Remove configuration documentation from config + files. It is redundant, error-prone, and difficult to maintain. + Configuration documentation is available in configs/README.txt for + common configurations and in configs/*/README.txt for board and MCU- + specific configurations. + * configs/stm3240g-eval: Add USB host support. + * sched/os_bring.c, configs/*/defconfig, tools/mkconfig.c, and others: Added + configuration variable CONFIG_USER_ENTRYPOINT that may be used to change + the default entry from user_start to some other symbol. Contributed by + Kate. NOTE: This change does introduce a minor backward incompatibility. + For example, if your application uses NSH as its start-up program, then your + build will now fail because it will be unable to find "user_start". The fix + for this link failure is to add the following to your configuration file: + CONFIG_USER_ENTRYPOINT="nsh_main". + * libs/stdio/lib_libfread.c and lib_*flush*.c: Correct a couple of + error cases where the lib semaphore was not be released on error + exits (thanks Ronen Vainish). Also, improved some error reporting: + the generic ERROR was being used instead of the specific errno + value; the errno variable was not always set correctly. + * tools/mkfsdata.pl: The uIP web server CGI image making perl script was + moved from apps/netutils/webserver/makefsdata to nuttx/tools/mkfsdata.pl + (Part of a larger change submitted by Max Holtzberg). + * configs/stm3240g-eval/script/ld.script: All of the identical ld.script + files for the STM3240G-EVAL were replaced by one version in this directory. + * configs/stm3240g-eval/webserver: Configuration submitted by Max Holtzberg + for testing the changes to the uIP web server (see apps/ChangeLog.txt). + * lib/stdio/lib_perror.c: Remove CONFIG_LIBC_PERROR_DEVNAME. What was I + thinking? Arbitrary streams cannot be shared by different tasks. + * tools/mksyscall.c, csvparser.c, and csvparser.h: Separate CSV parsing + logic from mksyscall.c into files where it can be shared. + * tools/mksymtab.c: Add a tool that can be used to convert a CSV file + into a NuttX-style symbol table. + * sched/work_cancel.c: Fix a bad assertion (reported by Mike Smith) + * configs/stm3210e-eval/src/up_idle.c: Correct some power management + compilation errors (reported by Diego Sanchez). + * include/nuttx/wqueue.h, sched/work*, and others: Added logic to support + a second, lower priority work queue (CONFIG_SCHED_LPWORK). + * arch/arm/src/stm32/stm32_dma.c, chip/stm32*_memorymap.h: FSMC SRAM is + only 16-bits wide and the SDIO DMA must be set up differently. + * arch/arm/src/stm32/stm32_dma.c: Back out the 16-bit DMA change. It + is incorrect. + * configs/: Make use of UART4/5 vs USART4/5 consistent in all places. + * Kconfig: Serial 2STOP setting must be integer 0/1, not a boolean. + * lib/misc/sendfile.c and include/sys/sendfile.h: Add a Linux style + sendfile() (non-standard!) + * Kconfig: Refactor serial settings (moved from chip to drivers/serial). + AVR "teensy" now builds with Kconfig (contributed by Richard Cochran). + * Kconfig: Add configuration settings for the LPC17xx + * Kconfig: Add configuration settings for the LM3S (from Richard Cochran). + * Kconfig: Verify configuration settings for the STM32. This includes + changes in the way that the external SRAM is configured: Define + CONFIG_HEAP2_SIZE (decimal) instead of CONFIG_HEAP2_END (hex). + * tools/configure.sh: Don't append the apps directory path setting + if the correct setting is already in defined in the defconfig file. + * fs/fat/fs_utils.c: Improperly constructed bool expression. This + would cause many unnecessary writes to FLASH (Thanks Ronen Vainish). + * Kconfig: Verify configuration settings for the LPC43xx. This includes + some corrections to configuration variable names and defconfig settings. + * Kconfig: Add and verify configuration settings for the LPC31xx. + * arch/arm/src/stm32/stm32_uart.h and stm32_serial.c: Add logic to + re-initialize the console UART as needed to enable DMA on the + console UART (contributed by Mike Smith). + * net/recvfrom.c, net/Kconfig, include/nuttx/net/uipopt.h: Remove delay + after receiving data. That has historical reasons to be there (it + was needed before read-ahead buffering was added), but kills performance. + (Noted by Max Holtzberg). + * configs/shenzhou: Add beginnings of a board configuration for the + Shenzhou STM32107 board (see www.armjishu.com). Very little is in + place as of this initial check-in. + * QEMU: Fixes from Richard Cochran to build QEMU with Kconfig files. + * arch/*/src/Makefile: Remove some old logic that was kicked off + when CONFIG_BOOT_RUNFROMFLASH=y. The old logic used to use + objcopy to move sections. Newer logic changes the load position + of sections in the linker script. As far as I can tell, there + is nothing in the source tree now that depends on the old way of + doing things (if I am wrong, they will need a change to the linker + script). + * configs/fire-stm32v2: Configuration for the M3 Wildfire board. I + don't know very much about this board other than is has an + STM32F103VET6 chip, LCD, touchscreen, and ENC28J60 network. Very + little is in place on the initial check-in. + * configs/shenzhou: Coding for the Shenzhou board port is complete, + but tested has been deferred until I get the right tools. + * arch/arc/include/stm32/chip.h and arch/arm/src/stm32/chip.h: + Add support for the STM32F103VET6. + * fs/fs_fdopen.c: Bad check for failure to allocate memory. (Noted + by Ronen Vainish). + * drivers/mmcsd/mmcsd_sdio.c: If the MMC/SD driver were ever + uninitialized then there would be a double release of memory + (Noted by Ronen Vainish). + * fs/mmap/fs_rammap.c: Fix logic error and errno check (contributed + by Kate). + * arch/avr/src: Fixes from AVR32 build errors that have crept in + over the time; incorporated Kconfig for AVR3 (Richard Cochran). + * fs/fat and include/nuttx/fs/fat.h: The FAT file system allocates + memory for sector I/O buffers used to exchange data with the + configured block driver. In some contexts, the block driver may + require DMA-capable memory. If CONFIG_FAT_DMAMEMORY is defined, + then the FAT FS will use platform-provided DMA memory allocators + to allocate the block driver I/O buffers. + * CONFIG_NET_ENC28J60 renamed CONFIG_ENC28J60 to be consistent + in all places. + * drivers/enc28j60.c, include/nuttx/net/enc28j60.h, and + olimex-strp711/src/up_enc28j60.c: No longer passes IRQ number + as a parameter. Instead now passes a call table to manage + ENC28J60 GPIO interrupts. That is because GPIO interrupts are + handled in different ways by different MCUs and some do not + support IRQ numbers for GPIO interrupts. + * mm/mm_gran* and include/nuttx/gran.h: Add a simple granule- + based allocator. The intent of this allocator is to support + simple allocation of DMA I/O buffers. The initial check-in + is code complete but untested (not event built into the + mm/Makefile yet. + * configs/fire-stm32v2: The board port is basically functional. + Not all features have been verified.

Contributed by Max Holtzberg. + * mm/README.txt: Add a new README file. + * include/nuttx/usb/usb.h, arch/*/src/*usb.c, and arch/*/src/*otg*.c: + Add hooks to use common, external DMA buffer allocation + implementation. + * net/recvfrom.c: Don't block in recvfrom if (1) read-ahead buffering + is enabled and (2) some data was obtained from read-ahead buffers. + Blocking is a bad idea in that case because there is no timeout! + (submitted by Max Holtzberg). + * configs/stm3240g-eval/xmlrpc: An example configuration for the + Embeddable Lightweight XML-RPC Server at apps/examples/xmlrpc. + See http://www.drdobbs.com/web-development/ + an-embeddable-lightweight-xml-rpc-server/184405364 for more info. + Contributed by Max Holtzberg. + * configs/*/nxwm/defconfig and sched/task_exithook.c: Fixes for + bugs that crept in during recent changes. (Submitted by Max + Holtzberg). + * arch/arm/include/armv7-m/irq.h: Fix a critical bug in irqsave(). + It looks like sometimes the compile will re-order some instructions + inapproapriately. This end result is that interrupts will get + stuck off. + * drivers/mtd/w25.c: Beginning of a driver for the Windbond SPI + FLASH family (W25x16, W25x32, and W25x64). The initial check-in + is basically just the SST25 driver with some name changes. + * arch/arm/include/armv7-m/irq.h and arch/arm/src/stm32/stm32_spi.c: + Back out the last change in irq.h. It is (most likely) fine the + way it was. The really interrupt related problem was in stm32_spi.c: + When SPI3 is not enabled, then the irqrestore() falls in the + else clause. + * include/nuttx/compiler.h and other files: Moved always_inline + and noinline __attributes__ here. Also replaced all occurrences + of explicit __atributes__ in other files with definitions from + this header file. + * drivers/mtd/w25.c: The Windbond SPI FLASH W25 FLASH driver is + code complete (but still untested). + * arch/arm/src/stm32/stm32_i2c.c: I2C improvements from Mike Smith. + Unified configuration logic; dynamic timeout calculations; + I2C reset logic to recover from locked devices on the bus. + * configs/*/*/Make.defs, tools/Config.mk, Makefile: Refactor all + common make definitions from the various Make.defs files into + the common tools/Config.mk. Add support for a verbosity options: + Specify V=1 on the make command line in order to see the exact + commands used in the build (Contributed by Richard Cochran). + * drivers/net/enc28j60.c: The ENC28J60 Ethernet driver is + now functional. + * configs/fire-stm32v2: Add support or the fire-stm32v3 board as + well (untested because I do not have a v3 board). + * lib/stdio/lib_sscanf.c: Add %n pseudo-format (from Kate). + * lib/stdio/lib_sscanf.c: There is an issue of handling input + when (1) no fieldwidth is provided and (2) there is no space + seperating the input values. No solutions is in place for this + case now (either space or a fieldwidth must be provided). But + at least some of the bad logic that attempted to handle this + case has been removed (noted by Kate). + * arch/arm/src/stm32/stm32_eth.c: DMA buffer sizes must be an + even multiple of 4, 8, or 16 bytes. + * arch/arm/src/stm32/stm32_idle.c: Fixes STM32F107 DMA issues: + We cannot go into sleep mode while Ethernet is actively DMAing. + * configs/shenzhou/src/up_ssd1289.c: Add infrastructure to support + SSD1289 LCD. Initial checkin is just a clone of the + STM32F4Discovery's FSMC-based LCD interface. The Shenzhou + will need a completely need bit-banging interface; this + initial check-in is only for the framework. + * configs/shenzhou/src/up_ssd1289.c: Bit-banging driver is + code complete. + * configs/shenzhou/src/up_lcd.c: Oops. Shenzhou LCD does not + have an SSD1289 controller. Its an ILI93xx. Ported the + STM3240G-EVAL ILI93xx driver to work on the Shenzhou board. + * configs/shenzhou/nxwm: Added an NxWM configuration for the + Shenzhou board. This is untested on initial check-in. It will + be used to verify the Shenzhou LCD driver (and eventually the + touchscreen driver). + * configs/shenzhou/src/up_touchscreen.c: Add ADS7843E touchscreen + support for the Shenzhou board.

Damn! + * binfmt/libelf: The basic ELF module execution appears fully functional. + * configs/shenzhou/src/up_relays.c: Add support for relays from the + Shenzhou board. Contributed by Darcy Gong. + * lib/fixedmath: Moved the old lib/math to lib/fixedmath to make room for + the math library from the Rhombus OS + * lib/math: Now contains the math library from the Rhombus OS by Nick Johnson + (submitted by Darcy Gong). + * include/float.h: Add a first cut at the float.h header file. This + really should be an architecture/toolchain-specific header file. It + is only used if CONFIG_ARCH_FLOAT_H is defined. + * lib/math: Files now conform to coding standards. Separated float, + double, and long double versions of code into separate files so that + they don't draw in so much un-necessary code when doing a dumb link. + * binfmt/libelf: The ELF loader is working correctly with C++ static + constructors and destructors and all. + * Documentation/NuttXBinfmt.html: Add documentation of the binary loader. + * configs/sim/ostest: Converted to use the mconf configuration tool. + * configs/sim/cxxtest: New test that will be used to verify the uClibc++ + port (eventually). + * include/nuttx/fs/fs.h, lib/stdio/lib_libfread.c, lib_ferror.c, + lib_feof.c, and lib_clearerr.c: Add support for ferror(), feof(), + and clearerror(). ferror() support is bogus at the moment (it + is equivalent to !feof()); the others should be good. + * configs/stm32f4discovery/include/board.h: Correct timer 2-7 + base frequency (provided by Freddie Chopin). + * include/nuttx/sched.h, sched/atexit.c, and sched/task_deletehook.c: + If both atexit() and on_exit() are enabled, then implement atexit() + as just a special caseof on_exit(). This assumes that the ABI can + handle receipt of more call parameters than the receiving function + expects. That is usually the case if parameters are passed in + registers. + * libxx/libxx_cxa_atexit(): Implements __cxa_atexit() + * configs/stm32f4discovery/cxxtest: New test that will be used to + verify the uClibc++ port (eventually). The sim platform turned not + to be a good platform for testing uClibc++. The sim example will not + run because the simulator will attempt to execute the static + constructors before main() starts. BUT... NuttX is not initialized + and this results in a crash. On the STM324Discovery, I will have + better control over when the static constructors run. + * RGMP 4.0 updated from Qiany Yu. + * configs/*/Make.defs and configs/*/ld.script: Massive clean-up + and standardization of linker scripts from Freddie Chopin. + * net/netdev_ioctl.c: Add interface state flags and ioctl calls + to bring network interfaces up and down (from Darcy Gong). + * config/stm32f4discovery: Enable C++ exceptions. Now the entire + apps/examples/cxxtest works -- meaning that the uClibc++ is + complete and verified for the STM32 platform. + +6.24 2012-12-20 Gregory Nutt + + * arch/arm/src/stm32: Support for STM32F100 high density chips + added by Freddie Chopin. + * configs/stm32f100_generic: Support for generic STM32F100RC board + contributed by Freddie Chopin. + * arch/arm/src/stm32_otgfsdev.c: Partial fix from Petteri Aimonen. + * drivers/lcd/ug-2864ambag01.c and include/nuttx/lcd/ug_2864ambag01.h: + LCD driver for the Univision OLED of the same name (untested on + initial check-in). + * configs/stm32f4discovery/nxlines: Configure to use mconf/Kconfig + tool. + * configs/stm32f4discovery/src/up_ug2864ambag01.c: Board-specific + initialization for UG-2864AMBAG01 OLED connecte to STM32F4Disovery. + * libxx/libxx_stdthrow.cxx: Exception stubs from Petteri Aimonen. + * configs/stm32f4discovery/src/up_ug2864ambag01.c: Driver has been + verified on the STM32F4Discovery platform. Some tuning of the + configuration could improve the presentation. Lower resolution displays + are also more subject to the "fat, flat line bug" that I need to fix + someday. See http://www.nuttx.org/doku.php?id=wiki:graphics:nxgraphics + for a description of the fat, flat line bug. + * libc: Renamed nuttx/lib to nuttx/libc to make space for a true lib/ + directory that will be forthcoming. Also rename libraries: liblib.a -> libc.a, + libulib.a -> libuc.a, libklib.a -> libkc.a, liblibxx.a ->libcxx.a. + (I will probably, eventually rename libxx to libcxx for consistency) + * Makefile, lib/: A new, empty directory that will hold generated libraries. + This simplifies the library patch calculations and lets me get rid of some + bash logic. The change is functional, but only partially complete; + additional logic is needed in the arch/*/src/Makefile's as well. Right + now that logic generate multiple library paths, all pointing to the lib/ + directory. + * arch/*/src/Makefile: Now uses only the libraries in lib/ + Replace bash fragments that test for board/Makefile. + * Makefile.win: The beginnings of a Windows-native build. This is just + the beginning and not yet ready for prime time use. + * configs/stm32f4discovery/winbuild: This is a version of the standard + NuttX OS test, but configured to build natively on Windows. Its only + real purpose is to very the native Windows build logic. + * tools/mkdeps.bat and tools/mkdeps.c: mkdeps.bat is a failed attempt + to leverage mkdeps.sh to CMD.exe. It fails because there are certain + critical CFLAG values that cannot be passed on the CMD.exe command line + (like '='). mkdeps.c is a work in progress that will, hopefully, + replace both mkdeps.sh and mkdeps.bat. + * tools/Config.mk: Centralize the definition of the script that will be + used to generated header file include paths for the compiler. This + needs to be centralized in order to support the Windows native build. + * tools/incdir.bat: A replacement for tools/incdir.sh for use with the + the Windows native build. + * Makefile.unix: The existing top-level Makefile has been renamed + Makefile.unix. + * Makefile: This is a new top-level Makefile that just includes + either Makefile.unix or Makefile.win + * configs/stm3240g-eval/src: Qencoder fixes from Ryan Sundberg. + * arch/arm/src/stm32/stm32_qencoder.c: TIM3 bug fix from Ryan Sundberg. + * tools/mkromfsimg.sh: Correct typo in an error message (Ryan Sundberg) + * arch/*/src/Makefile: Remove tftboot install and creation of System.map + for Windows native build. The first is a necessary change, the second + just needs re-implemented. + * configs/mirtoo: Update Mirtoo pin definitions for Release 2. Provided + by Konstantin Dimitrov. + * Fixed an uninitialized variable in the file system that can cause + assertions if DEBUG on (contributed by Lorenz Meier). + * Config.mk: Defined DELIM to be either / or \, depending upon + CONFIG_WINDOWS_NATIVE. This will allow me to eliminate a lot of + conditional logic elsewhere. + * nuttx/graphics: One a mouse button is pressed, continue to report all + mouse button events to the first window that received the initial + button down event, even if the mouse attempts to drag outside the + window. From Petteri Aimonen. + * nuttx/graphics/nxmu/nx_block.c: One more fix to the NX block message + logic from Petteri Aimonen. + * include/nuttx/wqueue.h: Some basic definitions to support a user- + space work queue (someday in the future). + * graphics/nxmu: Add semaphores so buffers messages that send buffers + will block until the buffer data has been acted upon. + * graphics/nxmw: Extended the blocked messages to cover mouse movement + and redraw events. These will also cause problems if sent to a window + while it is closing. + * arch/several: Change UARTs are enabled for i.MX, LM3S, eZ80, and M16C to + match how they are enabled for other architectures. + * configs/ez80f910200kitg: Convert to use mconf configuration. + * sched/pause.c: Implements the POSIX pause() function. + * eZ80: Lots of changes to eZ80 configurations and build logic as I + struggle to get a clean Windows build (still not working). + * configs/cloudctrl: Darcy Gong's CloudController board. This is a + small network relay development board. Based on the Shenzhou IV development + board design. It is based on the STM32F107VC MCU. + * arch/arm/src/stm32_serial.c and stm32_lowputc.c: Added optional RS-485 + direction bit control. From Freddie Chopin. + * Lots of build files: ARMv7-M and MIPS32 Make.defs now include a common + Toolchain.defs file that can be used to manage toolchains in a more + configurable way. Contributed by Mike Smith + * configs/stm32f4discovery/winbuild and configs/cloudctrl: Adapted to use + Mike's Toolchain.defs. + * tools/configure.sh: Adapted to handle paths and setenv.bat files correctly + for native Windows builds. + * More of build files: AVR and AVR32 Make.defs now include a common + Toolchain.defs file that can be used to manage toolchains in a more + configurable way. Contributed by Mike Smith + * tools/incdir.sh and incdir.bat: Add -s option to generate system header + file paths. + * nuttx/arch/arm/src/arm/Toolchain.defs: Add support for more ARM toolchains + (from Mike Smith). + * arch/arm/src/stm32/stm32f40xxx_rcc.c: Enabled FLASH prefetch (from Petteri + Aimonen). + * graphics/nxtk/nxtk_filltrapwindow.c: Correct an offset problem (from + Peterri Aimonen). + * graphics/nxglib/nxglib_splitline.c: Fix error in drawing of near horizontal + lines (from Peterri Aimonen). + * sched/task_exithook.c: Missing right bracket with certain conditional + compilation (thanks James Goppert). + * arch/arm/srch/stm32/stm32_otgfshost.c: Replace timeout handling; use + system tick instead of frame counter. The frame counter gets reset to + zero at 0x3fff making it error prone. + * arch/arm/src/stm32/stm32f20xx_rcc.c and stm32f40xx_rcc.c: Added option + CONFIG_STM32_FLASH_PREFETCH. FLASH prefetch will now only be enabled + if this option is selected. + * configs/ez80f910200zco/ostest: Now uses Kconfig/mconf configuration + tool. Updated to build in native Windows environment. Other ez80f910200zco + build scripts also updated. + * configs/z8f64200100kit/ostest: Update to same level as eZ80 configurations. + * nuttx/configs/z8f64200100kit/scripts/setenv.bat: Add support for native + Windows build. + * nuttx/arch/arm/src/lpc17xx/lpc17_i2c.c: Resources not being released when + I2C is uninitialized. + * cloudctrl/src/up_chipid.c and shenzhou/src/up_chipid.c: Add functions to + get chip ID. Contributed by Darcy Gong. These should not be board-dependent, + but should be in arch/arm/src/stm32 where they can be used from any board. + * sched/work_thread.c: Fix backward conditional compilation. This might + has caused a memory leak. From Freddie Chopin. + * configs//Make.defs: Fix typo -wstrict-prototypes should be + -Wstrict-prototypes (From Denis Carilki). + * arch/arm/src/calapyso/calypso_keypad.c: Add Calypso keypad driver. From + Denis Carilki. + * z8encore000zco/ostest and z8f64200100kit/ostest: Converted to use Kconfig/ + mconf configuration tool. + * arch/arm/src/armv7-m/up_exception.S: missing curly braces for push/pop + From Freddie Chopin. + * z8encore000zco/ostest and z8f64200100kit/ostest: Can now be modified to + support the Windows native builds (see corresponding README.txt files). + * configs/z16f2800100zcog - All configurations updated to use the ZDS-II + 5.0.1 toolchain. + * configs/z16f2800100zcog - All configurations updated to use Kconfig/mconf + configuration tools. + * configs/z16f2800100zcog/ostest - Now supports a native Windows build + (other ZNEO configs may also support the native build, but this has not + been verfiied). + * include/nuttx/input/keypad.h, arch/arm/src/calypso/calypso_keypad.c, and + configs/compal_e99/nsh_highram: First cut at a standard keypad interface + definition. Contributed by Denis Carikli. + * libc/stdlib/lib_rand.c: Always add one to result congruential generators + to avoid the value zero. Suggested by Freddie Chopin. + * tools/b16.c: Fixed precision math conversion utility. + * graphics/nxglib/nxglib_splitline.c: Fix the "fat, flat line bug" + * arch/z80/src/*/Toolchain.defs: Add dummy Toolchain.defs files for the + z80 family. + * configs/z80sim/ostest: Converted to build with the Kconfig/mconf tool. + Current configuration failed to build for me (Ubuntu 12.10, SDCC 3.2.0 + pre-built for Linux) due to a glibc memory corruptionerror in SDCC. + * configs/z80sim/ostest: Default is now the Windows native build. See + configs/z80sim/README.txt for instructions to convert back to a Linux or + or Cygwin build. + * arch/z80/src/Makefile.sdccw: Renamed makefiles with extensions zdiil, + zdiiw, sdccl, and sdccw for the ZDS-II vs SDCC compilers and for the + POSIX vs Windows native builds. + * nuttx/drivers/mtd/ftl.c: Fix for the flash translation layer. Short + unaligned writes were buggy. From Petteri Aimonen. + * nuttx/libc/math/lib_round*.c: Add rounding functions to the math + library. Contributed by Petteri Aimonen. + * include/cxx/cstdlib: Add stroul(). From Petteri Aimonen. + * arch/*/include/limits.h: Change signed minimum values from, for example, + (-128) to (-127 - 1) to avoid overflows under certain conditions. From + Peterri Aimonen. + * graphics/nxtk/nxtk_subwindowmove.c: Previously it was very difficult to + do e.g. "scroll by dx, dy". When given the full window area, nxtk_subwindowmove + would clip the offset always to 0,0. It makes more sense for it to clip the + source area and not modify the offset. From Petteri Aimonen. + * graphics/nxtk/nxtk_getwindow.c: Clipping would change the offset of returned + data, and caller has no way to know what the new offset would be. This messes + up font drawing when the text is partially out of window, e.g. when scrolling. + Also from Petteri Aimonen. + * include/stdbool.h: Can now be disabled for C++ files if CONFIG_C99_BOOL8 is + defined. CONFIG_C99_BOOL8 indicates (1) that the sizeof(_Bool) is one in both + C and C++, and (2) the C compiler is C99 and supports the _Bool intrinsic + type. Requested by Freddie Chopin. + * include/stdlib/lib_rand.c: Various additional changes so that the integer + value zero can be returned. Requested by Freddie Chopin. + * arch/z80/src/Makefile.sdcc*, z80/up_mem.h: Redesign Z80 build so that it + no longer depends on Bash scripts. + * configs/z80sim/nsh and pashello: Converted to (1) use the kconfig-frontends + configuration tool, and (2) to build natively under Windows. The NSH + configuration is verified; the pashello configuration needs a more TLC. + * tools/copydir.sh: Rename tools/winlink.sh to tools/copydir.sh + * tools/link.bat, unlink.bat, and copydir.bat: Add Windows counterparts + to the link.sh, unlink.sh, and copydir.sh Bash scripts. + * configs/z80sim/pashello: Now builds correctly. + * configs/xtrs/ostest, nsh, and pashello: Converted to (1) use the kconfig- + frontends configuration tool, and (2) to build natively under Windows. + * drivers/serial/Kconfig and sched/Kconfig: Two names for same configuration: + CONFIG_LOWLEVEL_CONSOLE is bogus and CONFIG_DEV_LOWCONSOLE is in the wrong + Kconfig file. Moved to drivers/serial/Kconfig replacing CONFIG_LOWLEVEL_CONSOLE. + * arch/z80/include/z180: Add header files for z180 chips. Initial versions + are just clones of z80 header files. + * arch/z80/src/z180: Add source files for z180 chips. Initial versions + are just clones of z80 source files. + * include/nuttx/arch.h: Add address environment control interfaces (for use + with CPUs the provide MCUs and support process-like address environments). + * arch/z80/src/z180/z180_mmu.*: Add MMU support for z180 tasks. + * configs/p112: Add very basic board support and an examples/ostest + configuration for the venerable P112 board. + * sched/os_bringup.c: If CONFIG_PATH_INITIAL is defined, then the initial + environment of the task started by os_bringup() will have the PATH + environment variable defined to be that string. + * binfmt/binfmt_exepath.c: If CONFIG_BINFMT_EXEPATH is defined, then this + file will be built. It contains logic to search for regular files at + the absolutes paths found in the current PATH environment variable + setting. This is untested and not yet hooked into the binfmt exec() + logic on initial check-in + * binfmt/binfmt_loadmodule.c: load_module() will now traverse the PATH + variable to locate files from their relative path. + * include/nuttx/arch.h and arch/z80/src/z180/z180_mmu.c: Restructure the + address environment interfaces so that they will better integrate with + binfmt/. + * binfmt/libelf/*, binfmt/libnxflat/* and other files: Integrate the + address environment interfaces. If CONFIG_ADDRENV=y, then binfmt/ + will now create an address environment for new tasks (instead of + just malloc'ing the task memory). + * configs/stm32f4discovery/elf: Enable support/test of the PATH + to find executables using a relative path. + +6.25 2013-02-01 Gregory Nutt + + * graphics/: Adds 5x8 monospace font.

NOTE + there is a issue of ARM9 systems with low vectors and large memories + that will have to be addressed in the future. + * libc/misc/lib_kbdencode.c and lib_kbddecode.c: Add logic to marshal + and serialize speical keyboard commands intermixed with normal ASCII + data (not yet hooked into anything). + * drivers/usbhost/usbhost_hidkbd.c: If CONFIG_HIDKBD_ENCODED is + defined, this driver will now use libc/misc/lib_kbdencode.c to + encode special function keys. + * configs/olimex-lpc1766stk/hidkbd: This configuration has been + converted to use the kconfig-frontends configuration tool. + * drivers/lcd/ug-2864hsweg01.c and include/nuttx/lcd/ug-2864hsweg01.h: + Driver for UG-2864HSWEG01 OLED contributed by Darcy Gong. + * configs/stm32f4discovery/src/up_ug2864hsweg01.c: Support for the + UG-2864HSWEG01 OLED for the STM32F4Discovery board. + * drivers/usbhost/usbhost_hidkbd.c: Correct a logic error in how + tasks waiting for read data are awakened. + * libc/misc/lib_kbdencode.c and lib_kbddecode.c: Now handles keypress + events too. However, the USB HID keyboard driver has not yet been + updated to detect key release events. That is kind of tricky in + the USB HID keyboard report data. + * configs/mcu123-214x/nsh: Converted to use the kconfig-frontends + configuration tool. + * configs/zp214xpa: Add basic support for the The0.net ZP213x/4xPA + board (with the LPC2148 and the UG_2864AMBAG01). + * configs/sim/nxlines: Add an nxlines configuration for the + simulator. + * configs/zp214xpa/nxlines: Add an nxlines configuration for the + ZP213x/4xPA (with the LPC2148 and the UG_2864AMBAG01).

This work-alike + program would be used in environments that do not support Bash + scripting (such as the Windows native environment). + * tools/configure.bat: configure.bat is a small Windows batch + file that can be used as a replacement for configure.sh in a + Windows native environment. configure.bat is actually just a + thin layer that executes configure.exe if it is available. If + configure.exe is not available, then configure.bat will attempt + to build it first. + * arch/arm/src/lpc17xx/lpc17_syscon.h: Correct some typos in bit + definitions (from Rommel Marcelo). + * libc/string/lib_strndup.c: strndup() should use strnlen(), not + strlen(), to determine the size of the string. + * sched/os_bringup.c: Remove support for CONFIG_BUILTIN_APP_START. + This is not really a useful feature and creates a violation of the + OS layered architecture. + * include/unistd.h, arch/arch/src/*: Implement a simple vfork(). + On initial checkin, this API is available only for ARM platforms. + * binfmt/binfmt_exec.c: exec() now sets the priority of the new task + to the same priority as the current task (instead of the arbirtrary + value of 50). + * libc/unisted/lib_execv.c and lib_execl.c: New, somewhat flawed, + implementations of execv() and execl(). + * tools/cfgdefine.c: Strips quotes from CONFIG_EXECFUNCS_SYMTAB + value. + * arch/arm/include/lm3s/chip.h: Move chip definitions into + public include area for compatibility with other architectures. + * arch/arm/src/lm3s/chip: Move register definition header files + into a new chip/ sub-directory. + * arch/arm/src/lm3s/lm3s_internal.h: Broke up into several + smaller header files. + * arch/arm/src/lm: Rename the arch/arm/src/lm3s directory to + arch/arm/src/lm so that is can support other members of the + Stellaris family. + * libc/spawn: Add file action interfaces needed by posix_spawn(). + * sched/clock_time2ticks.c: Another case where time was being + rounded down instead of up (from Mike Smith). + * libc/spawn: Implementation of posix_spawn() is complete but + untested and undocumented. + * drivers/usbdev/pl2303.c: Fix typols in the PL2303 driver + (from Max Holtzberg). + * configs/stm32f4discovery/posix_spawn: Added a configuration + that can be used for testing posix_spawn(). + * arch/arm/src/stm32: Bring F1 support for general DMA and serial + DMA in paricular up to parity with F2/F4 (from Mike Smith). + * libc/stdio/lib_libfread.c: Correct some error handling when + lib_fread() was passed a bad stream. Needed to move the + releasing of a semaphore inside of some conditional logic + (cosmetic). + * include/nuttx/sched.h, sched/task_setup.c, and sched/task_exithook.c: + Add support for remembering the parent task and sending + SIGCHLD to the parent when the task exists. + * sched/task_exithook.c: Fixed a *critical* bug. Here is + the scenario: (1) sched_lock() is called increments the lockcount + on the current TCB (i.e., the one at the head of the ready to run + list), (2) sched_mergepending is called which may change the task + at the head of the ready-to-run list, then (3) sched_unlock() is called + which decrements the lockcount on the wrong TCB. The failure case + that I saw was that pre-emption got disabled in the IDLE thread, + locking up the whole system. + * sched/sched_waitpid.c: Use SIGCHLD instead of a semaphore. This + is a much more spec-compliant implementation. However, there are + some issues with overrunning signals because NuttX does not support + queueing of signals (POSIX does not require it). I think it may + need to. + * sched/sched_waitid.c and sched_wait.c: Add support for waitid() + and wait(). See issues with waitpid() above. + * include/nuttx/fs/fs.h and fs/fs_files.c: Add a dup() method to + the struct mountpt_operations. When dup'ing a file that resides + on a mounted volume, let the file system's dup() method do the + work. + * fs/romfs/fs_romfs.c: Implemented the dup() method for the ROMFS + file system. + * fs/fat/fs_fat32.c, fs/nxffs/nxffs_initialize, and + fs/nfs/nfs_vfsops.c: Add hooks for dup() method (not yet + implemented). + * fs/romfs: Remove the rf_open flag.

It appears to be the same IP. + (2013-03-05) + * libc/wqueue: Work queue logic moved from sched/ to libc/wqueue. It + is not really core OS functionality and this move helps prepare for + user-space work queues. (2013-03-05) + * libc/wqueue: Implemented user-space work queues. These will not + get tested until the next time I attempt a NuttX kernel build. + (2013-03-05). + * arch/arm: Correct some bad syscall dispatching logic. This change + cannot be fully tested until there is a fielded NuttX kernel build. + (2013-03-06). + * net/net_poll.c: Correct logic that checks if the socket is + disconnected when the poll is setup. That is bad logic: Listen + sockets, for example, are not connected. In that case, the purpose of + the poll is to wait for connection events. As a result of this, + poll/select would return immediately with POLLHUP with it was used to + detect connection events. This fix for now was to check instead if + the socket is closed (meaning that it was connected at one time but + was closed by the remote peer). That excludes the listen socket which + was never connected. This does introduce a new problem, however. If + the socket was not closed, but lost the connection through an abnormal + event, then poll/select will hang. That needs to be revisited. + (2013-03-07) + * fs/fs_select.c: Was not checking if the timeout parameter was NULL + but would, instead, setup a bogus timeout based on whatever it found at + address zero. Also, improved some of the memory allocation logic so + that it will not use so much memory. (2013-03-07) + * net/net_poll.c: Handle the missing case. Now tests for not connected + AND not listening. I think that now covers all of the cases including + the missing case noted above. (2013-03-07) + * mm/: Move all memory manager globals into a structure. A reference + to this structure is now passed internally between mm APIs. This + change will (eventually) support multiple heaps and heap allocators. + (2013-03-08). + * mm/ and include/nuttx/mm.h: Implement support for multiple heaps. + (2013-03-08). + * arch/*/src: xyz_addregion() needs to call kmm_addregion, not mm_addregion. + (2013-03-08). + * sched/kmm*.c: Move this garbage kmm*.c file to mm/. until I decide what + to do with them (which is probably to just delete them). (2013-03-08). + * mm/mm_test.c and Makefile.test: Deleted the memory test. This was + a good test and helped me a lot when I wrote the memory manager, but + now it is in the way and paralyzing other efforts. So the memory unit + test was deleted. (2013-03-08) + * sched/sched_free.c: Rename sched_free() to sched_ufree(); Add + sched_kfree() to handler deferred kernel heap allocations. (2013-03-10) + * arch/: User user-accessible heap to allocate all stacks. (2013-03-10) + * arch/arm/src/sam3u: The AT91SAM3U will now support a kernel heap if + so configured.

(2013-03-13). + * arch/: Rename g_heapbase to g_idle_topstack. This is the same value + however: The top of the IDLE stack is the same as the base of the + heap in the flat build. But not in the kernel build: The base of + the heap is elsewhere so the naming was wrong. (2013-03-13). + * libc/stdlib/lib_itoa.c: Implementation of itoa() contributed by + Ryan Sundberg.

In the current design, this can + happen only under one condition: When the kernel system call logic calls + back into user space in order to allocate user space memory. So it is + expected that the maximum nesting level will be only 2 (2013-03-17). + * libc/stdio/lib_sccanf.c: Correct an error in sscanf. If %n occurs in + the format statement after the input data stream has been fully + parsed, the %n format specifier will not be handled. Reported by + Lorenz Meier (and also earlier by Kate) (2013-03-17). + * drivers/serial/serial.c: Support for O_NONBLOCK was not supported + in the "upper half" serial driver.

The FAT logic was + not making a distinction between directory non-existence and file + non-existence so when it you try to create a file in a non-existent + directory, it would create a file with the name of the missing + directory. Reported by Andrew Tridgell (2013-03-30). + * Numerous files: Changed the protoypes of up_create_stack() and + up_release_stack() so that is includes a task type.

Only the prototypes were changed on this + big, initial checkin. The next step will be to add logic to + allocate stacks for kernel threads from protected kernel memory + and all other task types from unprotected user memory (2013-03-20). + * arch/*/src/common/up_createstack.c, up_use_stack.c, and + up_release_stack.c: If creating or releasing the stack for a kernel + thread, use the kernel allocator so that the kernel thread stacks + are protected from user application meddling (2013-03-20). + * arch/arm/src/armv[6|7]-m/up_scall.c: Fix parameter passing for + all system call inline functions with > 3 parameters (2013-03-20) + * arch/*/src/common/up_stackframe.c and include/nuttx/arch.h: Add + and new interface to set aside memory on the stack. This will be + used at least in the kernel build to hold task arguments (2013-03-21). + * sched/sig_deliver.c: When dispatching signals to user threads, + copy the siginfo_t from the sigq to the stack. The signal queue + is allocated from kernel memory; however, the current stack is + the user's stack and the user code will be able to access the + signinfo_t data from the stack copy (2013-03-21). + * arch/arm/src/stm32: Added support for the kernel mode build + (cloned from the lpc17xx). (2013-03-21). + * configs/stme32f4discovery/kernel and scripts: Add support for + the kernel mode build on the STM32F4Discovery (2013-03-21). + * drivers/st7567.c/h and include/nuttx/lcd/st7567.h: Driver for + the ST7567 LCD Display Module from Univision Technology Inc. + contributed by Manikandan.S (2013-03-22). + * configs/zkit-arm-1769: Now supports the ST7567 LCD display + module.

The original implementation was C-based + and simpler. However, the C code intermixed with SVC calls was + not properly preserving registers. The more complex, assembly + language version does not suffer from these issues. I believe + the kernel build can now be called "feature complete" + (2013-03-23). + * binfmt/binfmt_execmodule.c: Here is a place where I forget + to update the call to sched_releasetcb() to pass the thread + type as the second parameter (2013-03-23). + * arch/arm/src/lm, kinetis, lpc43, and nuc1xx: Add kernel build + support to all ARMv7-M and ARMv6-M chips.

This appears to be the last show-stopper bug: The + LaunchPad now runs NuttX! (2013-03-24). + * configs/lm4f120-launchpad/nsh: Add an NSH configuration for the + LaunchPad (2013-03-24). + * configs/kwikstik-k40: Converted configurations to use the + konfig-frontends tool (2013-03-25). + * configs/twr-k60n512: Converted configurations to use the + konfig-frontends tool (2013-03-25). + * arch/arm/src/lpc17xx/lpc17_lcd.c: Add an LCD framebuffer driver + for the LPC177x/8x family (2013-3-26). + * arch/arm/src/lpc17xx/lpc17_emc.c and + configs/open1788/src/lpc17_sdraminitialize.c: Began testing the + Open1788 SDRAM. The SDRAM is basically functional, but there are + failures with the SDRAM is stressed by the memory test at + apps/example/ramtest (SDRAM support and the RAM test can be configured + into the base configs/open1788/nsh configuration as described in + configs/open1788/READMT.txt (2013-3-27). + * configs/open1788/nxlines: Add a configuration to test both the + Open1788 LCD and SDRAM which is used as a framebuffer (2013-3-27). + * arch/arm/src/lpc17xx/lpc17_gdma.c and lpc17_sdcard.c: Began + implementation of the LPC17 DMA and integration into the SDCARD + driver (2013-3-29). + * arch/arm/src/lpc17xx/lpc17_gdma.c: LPC17 DMA is code complete and + under test. Does not yet work (2013-3-30). + * fs/fat/fs_fat32dirent.c and fs_fat32util.c: Several fixes to the + FAT file system from Ronen Vainish. These fixes mostly involve the + logic to extend directory clusters for the case of long file names + but also include a few important general fixes (such as for storing + 32 bit FAT values) (2013-03-31). + * arch/arm/src/lpc17xx/lpc17_gdma.c and lpc17_sdcard.c: SD card DMA + is now functional. Thre may be some issues with DMA from CPU SRAM + which is apparently disabled in sleep mode; up_idle() always enters + sleep mode (2013-03-31). + * arch/arm/src/stm32: Add architecure support for the STM32 F427/F437 + chips. Contributed by Mike Smith (2013-4-01). + * configs/zkit-arm-1769/src/up_can.c: Add support for both CAN1 + and CAN2.

But this raises a problem when the + MCU has multiple blocks for differ SPI implementations as does the + LPC17xx (and also as does other architectures like STM32 that have + USARTs that can serve as SPI interfaces as well). These were renamed + to lpc17_spiinitialize() and lpc17_sspinitialize() in this case. + Problem reported by M. Kannan (2013-4-01). + * arch/arm/src/lpc17xx/lpc17_gpdma.c and lpc17_idle.c: In sleep mode, + DMA can only be performed from peripheral SRAM. CPU SRAM is shutdown + in sleep mode. In order to simplify DMA memory allocation, the LPC17xx + IDLE will now hold off going to sleep mode if there is a DMA in progress + (2013-4-01). + * configs/open1788/src/lpc17_autoleds.c: Reversed sense of the IDLE LCD. + It is now off when the LPC17 is sleeping and on when awake. That is + much more useful because it provides a good visual indication of the + dynamic CPU load (2013-4-01). + * configs/open1788/src/lpc17_touchscreen.c and lpc17_ssp.c: Add + support for the touschscreen on the WaveShare LCD (2013-4-01). + * configs/several: There were already some functions called + lpc17_sspinitialize(). So they had to be renamed (2013-4-01). + * arch/arm/src/lpc17xx/lpc17_ssp.c: Adapted to work with the LPC178x + family (2013-4-01). + * arch/arm/src/lpc17xx/lpc17_gpio.c/.h: Separate LPC176x and LPC178x + logic into separate files. The logic is diverging to much to + try to retain common code (2013-4-03). + * net/net_clone.c: Fix compilation error when socket options are + are disabled.

So remove the second extension + $(NUTTX)$(EXEEXT) in two places (2013-4-7). + * arch/arm/src/lpc17xx/lpc17_gpioint.c: Disable interrupts in + lpc17_setintedge(). This logic must be atomic because it can be + re-entered before it completes enabled interrupts, sometimes + leaving the interrupts in a strange state (2013-4-7). + * arch/arm/src/lpc17_lcd.c: Rommel Marcelo got the LPC1788 + framebuffer-based LCD working. Very nice! (2013-4-08). + * arch/arm/src/lm/lm_clockconfig.c and configs/lm4f120-launchpad: + Fix handling of the RCC SYSDIV2 field when the PLL output is + 400MHz.

Fix + a major screw-up: The Cortex-M0 has no BASEPRI register but + the current logic was using it to manage interrupts. Switch + to using the PRIMASK. This means that hardfaults will (again) + occur when SVC instructions are executed (2013-4-16). + * configs/stm3240g-eval/ostest: Converted to use the kconfig-frontends + tools (2013-4-17). + * sched/task_exithook.c: Don't flush the streams until the + final thread of the group exits. Flushing may cause the + thread to get suspended at a bad time and other threads in the + group may run while the exiting thread is in an unhealthy state. + This can cause crashes under certain circumstance. This is a + critical bugfix (2013-4-18). + * drivers/mtd/ramtron.c: Extended to support the FM25V01 device. + Contributed by Lorenz Meier (2013-4-18). + * sched/task_deletecurrent.c and task_exit.c, arch/*/up_exit.c: + Renamed task_deletecurrent() and task_exit() since it really + handles the architecture independent part of _exit(). _exit() + is used internally, but if it is called from the user, it should + unregister any atexit() or on_exit() functions (2013-4-18). + * tools/kconfig2html.c: This is the beginning of a tool to + replace the hand-generated documentation of the NuttX configuration + variables with auto-generated documentation.

Fix this and + also backported the changes to SAM3/4 (untested). Now HSCMI is + functional on the SAMA5 with DMA! (2013-8-10). + * arch/arm/src/sam34/sam3u_periphclks.h: Correct a typo in a register + name (2013-8-10). + * drivers/mmcsd/mmcsd_sdio.c: Correction for a bad return value + when multiple block SDIO transfers are suppressed.

This will require significant changes + to the USB host interfaces starting with these chnages to monitor + connections on a port-by-port basis. This effects a lot of files and + more changes are coming for this issues. Changes are being blindly + incorporated into other architrectures. I am being careful to avoid + breakage, but I expect some (2013-8-12). + * configs/olimex-stm32-p107/nsh/defconfig and appconfig: Converted to + use the kconfig-frontends tool.

I think all architectures have this re-entrancy + than can result in serial interrupt being disabled, but I have only + seen the symptom on SAMA5 (2013-8-13). + * includes/nuttx/usb/usbhost.h and many other affected files: Separate + wait() and enumerate() methods from struct usbhost_driver_s and move + to new interface, struct usbhost_connection_s. This is part of the + necessary restructuring of the USB host interface to support multiple + root hub ports (2013-8-13). + * arch/arm/src/sama5/sam_ohci.c: Major restructuring of the driver due + in order to handle multiple root hub ports. Basically instead of one + driver structure with an arrayof root hub port structures, there is no + one container structure with an array of driver structures, one for + each root hub port. The advantage is that each class->driver call not + passes information associated with the RHport implicitly. The klugey, + procedural alternative was to add the function address to every + interface method (which I started to do but backed above) (2013-8-13). + * arch/arm/src/sama5/sam_memories.c and .h: Extended logic so do + conversions from physical to virtual addresses (2013-8-14). + * arch/arm/src/sama5/sam_ohci.c: Add D cache contols and conversion + between physical and virtual address (2013-8-14). + * arch/arm/src/stm32/stm32_spi.c: nbits() interface extended to + control bit order as well as bit width (from Teemu Pirinen) + (2013-8-16) + * arch/arm/src/sama5/sam_ohci.c: More to be tested, but the SAMA5 + OHCI driver is now basically funtional (2013-8-16). + * include/nuttx/usb/ehci.h: EHCI header file (2013-8-17). + * arch/arm/src/stm32/stm32_i2c.c: Correct an error that crept into + the STM32 F1 I2C driver with some recent changes.

This logic does not + currently hook into into anything. It will someday be a part of the + NuttX USB hub implementation (2013-8-18). + * nuttx/arch/arm/src/sama5/sam_ehci.c and other files: Create a skeleton + environment for development of an EHCI driver. Not much in place yet + (2013-8-20). + * nuttx/arch/arm/src/sama5/sam_ehci.c: Now code complete for all + asynchronous endpoints (control and bulk); nothing yet in place + for periodic endponts (interrupt and isochronous) (2013-8-22). + * include/nuttx/serial/serial.h and arch/arm/src/stm32/chip/stm32f40xxx_pinmap.h: + SourceForge bug #16 Fix IO pin map.

From Max Holtzberg (2013-6-26). + * include/nuttx/usb/usbhost.h, drivers/usbhost/usbhost_enumerate.c, and + all USB host drivers: Added a new driver method: getdevinfo. This + method is intended to get various information about the connected device, + but currently returns only the device speed. The device speed is + necessary by usbhost_enumerate in order to set a credible initial EP0 + max packetsize. High speed needs 64 bytes, low speed needs 8 bytes, + and full speed can handle almost any size (2013-8-26). + * arch/arm: Add hooks for Cortex-A8.

This + one differs from sst25.c because it supports larger SST25 parts: In + the larger parts support page write instead of byte/word writes like + the smaller parts. From Ken Pettit (2013-11-28). + * drivers/mtd/smart.c: Fixes a minor bug with SMART partition number + reporting (that would only be seen if both partition support and + multi-root directory support are enabled at the same time). From Ken + Pettit (2013-11-28). + * arch/arm/src/stm32/chip/stm32f40xxx_gpio.h: Add support for GPIOK and + GPIOJ.

From Ken + Pettit (2013-11-28). + * fs/fs_inode.c: The inode semaphore must be re-entrant. Here is the + re-entering path that I found: (1) USB host connects to FLASH drive + and creates /dev/sda, (2) /dev/sda is mounted, (3) FLASH drive is + removed but /dev/sda is not destroyed because there is still a + reference on the device because of the mount, (4) umount() is called, + taking the inode semaphore, now the driver tries to destroy the block + driver by calling unregister_blockdriver(). But (5) + unregister_blockdriver() also takes the inode semaphore causing a + deadlock if the inode semaphore is not re-entrant.

NAND can report read errors because of bad ECC. Logic + in NXFFS must account for it and not just throw in the towel every + time a read fails (2013-11-30). + * drivers/mtd/mtd_nand* and arch/arm/src/sama5/sam_nand.c: NAND + accesses now work (at least with software ECC and now DMA). Still + lots of testing to be done (2013-11-30). + * fs/nxffs/nxffs_dump.c: Do not abort on a read error. Just not + the error and continue. Otherwise, we would not be able to dump + NAND FLASH (2013-11-30). + * fs/nxffs: All read error logic has been revisited and modified in + most places. If we are using NAND, then read errors probably mean + that the block that was read contains uncorrectable bit errors. In + this case, we cannot just give up and abort the operations. Rather, + we need to treat read error like normal bad blocks in order to work + with NAND (2013-12-2). + * fs/nxffs/Kconfig and nxffs_initialize.c: Make the start up scan of + the media option. It just takes to long!

Because (1) + interrupts are already disabled on interrupt entry, (2) this + interferes with controlling the IRQ interrupt setting from interrupt + handlers, and (3) up_disable_irq() does not work anyway so that this + has never done anything (2014-1-15). + * All implementations of up_disable_irq() for all Cortex-M3 and M4 + architectures: To enable an interrupt on the Cortex-M3/4 CPU, you + need to set a bit in the ISER registet on the Cortex-M3/4 CPU, you + need to set a bit in the ISER register. To disable the interrupt, you + need to set a bit in the ICER register. Existing logic was trying to + disable interrupts by clearing the bit in the ISER register. That will + not work; writing a '0' to the ISER register has no effect. That + means that up_disable_irq() was doing nothing! It turns out that that + is not really important because up_disable_irq() is not really used + for that purpose. But some spurious STM32 ADC interrupts have been + reported to me and this turned out to be the cause in that case. My + concern now that up_disable_irq() works is that there may now be + unmasked bugs that leave devices in the disabled state?

The default need not be used. This is really only + useful when CONFIG_ARCH_BOARD_CUSTOM is selected and there is no + meaningful default sub-directory (2014-1-16). + * configs/Kconfig: Backed out the previous change for two reasons: + (1) it has a bad side effect in that the sub-directory setting + no longer tracks the board setting, and (2) you still can't + source the Kconfig file from the custom board directory (2014-1-16). + * Makefile.unix, Makefile.win, and configs/Kconfig: After thinking a + little harder, I re-implemented the backed-out custom configuration + feature. The new version does not have bad side-effect (1) (but still + has bad side-effect (2)) (2014-1-16). + * arch/x86/Kconfig and configs/qemu-i486/nsh/Make.defs and + ostest/Make.defs: Add a configuration option to select the -m32 + compiler option when building for a 32-bit target on a native 64-bit + compiler (2014-1-18). + * include/ctype.h: Typo in macro name: iscntrl, not iscontrol (2104-1-17) + * libc/unistd/lib_getopt.c: If there are no arguments (argc == 1), then + getopt() will leave the optind variable in an undefined state (2014-1-20). + * configs/olimex-stm32-p107: Fails to build if SPI3 for UEXT is not + remapped.

From Richard + Cochran (2014-1-23). + * arch/arm/src/armv7-m/up_memcpy.S: Assembler changes with the gcc-47 + distribution from ARM mean that we need to be explicit about branch + sizes; one or more of the wide branch opcodes results in bad table + branching. From Mike Smith (2014-1-23). + * Many files: renamed up_buttoninit() to board_button_initialize to + better conform to the naming standard. Now ONLY prototypes in + include/nuttx/arch.h (2014-1024). + * Rename up_buttons() to board_buttons() for the same reason (2014- + 1-14). + * Rename up_irqbutton() to board_button_irq() (2014-1-24). + * Rename up_ledinit() to board_led_initialize() (2014-1-24). + * Rename up_ledon() to board_led_on() and up_ledoff() to board_led_off() + (2014-1-24). + * arch/x86/src/qemu-i486/gemu_head.S: Patch from Matt Campbell + to fix 'Error: .size expression for idle_stack does not evaluate to + a constant" (2014-1-25). + * arch/arm/include/efm32, arch/arm/src/efm32, and configs/efm32-dk360: + Removed all EFM32 support.

This must be done with JP23 open. + It is performed only from the DRAMBOOT loader (2014-7-28). + * drivers/audio/wm8904.c: Fix some compile problems with the WM8904 driver + due to recent audio subsystem changes (2014-7-28). + * arch/arm/src/sama5/sam_timerisr.c and configs/sama5d3*/include/board*.h: + Correct system timer frequency. Input clock is MCK/2, not MCK + (2014-7-29). + * fs/fs_automount.c and include/nuttx/fs/automount.h (plus hooks in other + files): Add support for an auto-mounter that will automatically mount + and unmount a file system a media is inserted and removed (2014-7-29 . + * configs/sama5d4-ek/src/sam_automount.c: Add automounter support for + HSMCI0 and HSMCI1 (2014-7-29). + * configs/sama5d4-ek/Kconfig and src/sam_hsmci.c: Minor warning/latent + bug clean-up of auto-mounter logic (2014-7-29). + * configs/sama5d4-ek/README.txt anand src/sam_nsh.c, fs/fs_automount.c, + and include/nuttx/fs/automount.h: Cosmetic updates to comments and + README files and some naming (2014-7-29). + * configs/sama5d4-ek/nsh/defconfig and nxwm/defconfig: The SAMA5D4-EK + NSH and NxWM configurations now have the auto-mounter configured to + automatically mount the FAT file system on HSMCI0 at /mnt/sdcard + (2014-7-29). + * arch/arm/src/sama5/sam_hsmci.c: Add method to do RX transfer without + DMA. The 8-byte SCR transfer was failing silently with the DMA + transfer, leaving the SD card in single bit mode (2014-7-29). + * arch/arm/src/sama5/sam_hsmci.c: Fix a problem on card insertion/removal + callback handling. Interrupts were being disable so that the callbacks + occurred with interrupts disabled. This resulted in loss of some + interrupts and some not-so-good behaviors. The solution is to perform + all callbacks on the work thread unconditionally (2014-7-30). + * nuttx/fs/fs_automount.c: Auto-mounter: Fix state setting. Not + harmful other than it can cause a debug assertion to fire if you + manually unmount the media before removing it which is, of course, + what you are supposed to do (2014-7-30). + * arch/arm/src/sama5/sam_hsmci.c and README files: Re-enable TX DMA and + verify that DMA writes to the SD card are functional. They are so now + TX DMA is re-enabled in the driver. This might affect the SAMA5D3 + platforms where the TX DMA problem was found. The SAMA4D3 and 4 use + the same HSMCI driver. Much has change since then and it is not + surprising that DMA is now functional. However, the has not be re- + verified on the SAMA5D3 which has a different DMA controller + (2014-7-30). + * arch/arm/src/sama5/sam_dmac.c, sam_pio.c, and sam_pioirq.c: Changes + needed for a clean SAMA5D3 build after all of the recent SAMA5D4 + changes (2014-7-31). + * configs/sama5d3x-ek/nsh/defconfig: Refresh configuration (2014-7-31). + * configs/sama5d3x-ek/Kconfig, README.txt, src/sam_wm8904.c, Makefile, + sam_nsh.c, and sama5d3x-ek.h: Add support for the WM8904 audio CODEC + (2014-7-31). + * configs/sama5d3x-ek/nxplayer: Add a configuration to support the + command line NxPlayer (2014-7-31). + * audio/audio.c: More debug output (2014-7-31). + * configs/sama5d3x-ek/README.txt: REAME update (2014-7-31). + * drivers/audio/wm8904.c: Was not saving I2S interface instance + (2014-7-31). + * sched/sem_wait.c: Use set_errno() and get_errno().

This used to be done by looking + for the first partial buffer. That does not work with the in-place + sub-sampling performed by the PCM decoder: That always reduces the + size of the buffer so that all buffers only partially filled by the + time they get to the leaf. Now, a flag is set in the audio buffer + flags set to indicate the final buffer in the stream (2014-7-31). + * arch/arm/src/sama5/sam_ssc.c: Needs to account for data offset in + audio buffer (2014-7-31). + * drivers/audio/wm8904.c: Can't reset the WM8904 unless we also + reinitialize all registers. Try to get a saner timeout based on + sample rate, bits-per-sample, and buffer size (2014-7-31). + * arch/arm/src/sama5/Kconfig and sam_ssc.c: SCC Frame Synch Delay and + Start Delay are now configurable (2014-8-1). + * drivers/audio/wm8904_debug.c: Add logic to dump WM8904 registers + (2014-8-1). + * drivers/audio/wm8904.c: Fix an error in write logic. I am not sure + why this fixes the problem (2014-8-1). + * include/nuttx/audio/wm8904.h (and implementers of the interface): + the WM8904 driver needs to know the frequency of the MCLK in order + to set up the FLL to generate the correct bitrate (2014-8-1). + * WM8904: Add an option to control WM8904 register dumping (2014-8-2). + * WM8904: Add logic to program the FLL to achieve the bitrate + (2014-8-1). + * arch/arm/src/sama5/sam_ssc.c: Verify that the requested bit width + is supported. Correct some alignment tests that depend upon the data + bit width (2014-8-2). + * audio/pcm_decode.c: Correct the end of audio stream handling. It was + not being detected before so that logic was not examining the WAV + header in the first buffer of the next audio file (2014-8-2). + * configs/sama5d3x-ek/nxplayer/defconfig: Update with last WM8904 + settings (2014-8-2). + * drivers/audio/wm8904.c: Disable the FFL at the end of playing + (2014-8-2). + * include/nuttx/audio/wm8904.h: Fix wm8904_dump_registers macro: + Wrong number of parameters (2014-8-2). + * arch/arm/src/sama5/sam_pck.* and all SAMA5D board header files: + Add Main clock as an option for the PCK clock source (2014-8-3). + * configs/sama5d*-ek/Kconfig and src/sam_wm8904.c: Add option to + use MAINCK as source fort he WM8904 MCLK (2015-8-3). + * include/nuttx/audio/wm8904.h, configs/sama5d3x-ek/src/sam_wm8904.cm, + and sama5d4-ek/src/sam_wm8904.c: WM8904 interface enable method now + returns the previous interrupt state (2014-8-4). + * configs/sama5d3x-ek/src/sama5d3x-ek.h and sama5d4-ek/src/sama5d4-ek.h: + Correct the WM8904 interrupt configuration, active high level. Fix + that and don't pull-up (2014-8-4). + * configs/sama5d3x-ek/src/sam_wm8904.cm, and sama5d4-ek/src/sam_wm8904.c: + Correct ordering of some WM8904initialization: Need to provide MCLK + before initializing the WM8904, not after (2014-8-4). + * drivers/audio/wm8904.c and .h: Correct calculation of bitrate (I am + not sure why this is correct). LR clock divisor is now a constant 32- + bits per frame. Conditioned out interrupt logic; it is not being used. + Also added some FLL lock interrupt/poll logic (which was subsequently + disabled) (2014-8-4). + * SAMA5D3x-EK and SAMA4D4-EK: Add/update usage documents for media + players (2014-8-4). + * drivers/audio/wm8904.c and .h: Add reset logic to put the part back + in its initial state after playing each WAV file. Base samples per + second on frame length, not bits-per-sample. Use a different frame + length for 8-bit and 16-bit data (2014-8-4). + * arch/arm/src/sama5/sam_hsmci.c: TX DMA is again disabled for the + SAMA5D3 family. Although it works with the SAMA5D4 (which has a + different DMA subsystem), it does not work with the SAMA5D3 (2014-8-5, + see also 2014-7-30). + * audio/pcm_decode.c: Handle errors in the PCM WAV file in a way that + the Nxplayer can recover gracefully: Send and Audio Complete message + (2014-8-5). + * arch/*/src/*/*_timerisr.c, up_initialize.c, and up_internal.h: Re-name + up_timerinit() to up_timer_initialize() for compatibility with new + tickless OS interface name (2014-8-6). + * arch/*/src/*/Make.def: Don't build existing timer initialization + logic if CONFIG_SCHED_TICKLESS is defined (2014-8-6). + * include/nuttx/arch.h: First cut at platform-specific interfaces + needed to support tickless OS option (2014-8-6). + * sched/Kconfig: Add a new option CONFIG_SCHED_TICKLESS to enable the + tickless OS. This is a work in progress but should be relatively + safe since the new features are only enabled by this option (Safer + but not 100% safe since it does not protect from typos and other + dumb errors) (2014-8-6). + * arch/sim/src/Makefile, up_idle.c, up_internal.h, and up_tickless.c: + Add support for a simulated interval timer support verification of + the tickless OS (2014-8-6). + * include/nuttx/arch.h: Added another tickless OS interface to get + the timer remaining on the interval timer (2014-8-6). + * include/nuttx/clock.h, sched/clock_initialize.c and clock_internal.h: + If CONFIG_SCHED_TICKLESS is defined, then the global variable + g_system_timer does not exist (2014-8-6). + * sched/Makefile: Don't build in sched_processtimer.c if + CONFIG_SCHED_TICKLESS is selected (2014-8-6). + * sched/clock_gettime.c and clock_settime.c: Use the clock_systimer() + macro, do access the g_system_timer() global directly (2014-8-6). + * sched/clock_systimer.c: Uses interval timer interfaces to get the + time if CONFIG_SCHED_TICKLESS is selected (2014-8-6). + * sched/sched_timerexpiration.c, Makefile, os_internal.h, + sched_addreadytorun.c, sched_processtimer.c, sched_unlock.c, + wd_cancel.c, wd_internal.h, and wd_start.c: Implements the + tickless OS (2014-8-7). + * Many files: Remove CONFIG_DISABLE_CLOCK. Why? This option is not + really very useful and was only selected in a few unusable, mostly + unusable configurations anyway (m9s12/ostest, kl25z/minnsh, + z180/ostest, 8051, sh1, z80, and z8). The only real loss is probably + to the kl25z/minsh configuration . And with the addition of the + tickless OS, I just wanted to make the pain go away (2014-8-7). + * Many files: Change CONFIG_MSEC_PER_TICK to CONFIG_USEC_PER_TICK. + This gives more options for system timers in general, but more + importantly, let's us realize higher resolution for the case of + CONFIG_SCHED_TICKLESS=y -- of course, at the risk of some new + integer overflow problems 2014-8-7). + * Many files: Change all time conversions. Yech. New timer units + in microseconds breaks all existing logic that used milliseconds + in the conversions. Something likely got broken doing this, + probably because I confused a MSEC2TICK conversion with a TICK2MSEC + conversion (2014-8-7). + * arch/sim/src/up_tickless.c and sched/sched_timerexpiration.c: The + tickless OS now appears fully functional and passes the OS test + on the simulator with no errors (2014-8-7). + * sched/mqueue: Move POSIX message queue files from sched/ to + sched/mqueue (2014-8-8). + * sched/signal: Move signal-related files from sched/ to sched/signal + (2014-8-8). + * sched/pthread: Move all pthread files from sched/ to sched/pthread + (2014-8-8). + * sched/semaphore: Move POSIX counting semaphore files from sched/ to + sched/semaphore (2014-8-8). + * sched/environ: Move environment files from sched/ to sched/environ + (2014-8-8). + * sched/group: Move group logic from sched/ to sched/group (2014-8-8). + * sched/wdog: Move watchdog functions from sched/ to sched/wdog + (2014-8-8). + * sched/irq: Move interrupt dispatch logic from sched/ to sched/irq + (2014-8-8). + * sched/clock: Move clock functions from sched/ to sched/clock + (2014-8-8). + * sched/timer: Move POSIX timer files from sched/ to sched/timer + (2014-8-8). + * sched/paging: Move page fill sources from sched/ to sched/paging + (2014-8-8). + * sched/init: Move initialization functions from sched/ to sched/init + (2014-8-8). + * sched/errno: Move errno related files from sched/ to sched/errno + (2014-8-8). + * sched/task: Move task control files from sched/ to sched/task + (2014-8-8). + * sched/: Move a few files in sched/ that did not seem to have a home to + sched/signal and sched/task (2014-8-8). + * sched/sched: Move scheduler files from sched/ to sched/sched + (2014-8-8). + * (Many files): Replace os_internal.h with sched/sched.h in files that + actually reference something in sched.h (2014-8-8). + * sched/task/exit.c: Move sched/exit.c to sched/task/exit.c (2014-8-8). + * (Many files): Remove os_internal.h it has been replace by several new + header files under sched/. There have been some sneak inclusion paths + via os_internal.h, so expect a few compilation errors for some + architectures (2014-8-8). + * Documentation/NuttxPortingGuide.html, arch/sim/src/up_tickless.c, and + include/nuttx/arch.h: Fix errors in documentation and comments related + to the Tickless OS. From Vijay Kumar (2014-9-9). + * arch/arm/src/sama5/sam_tc.c and .h: Can now handle non-constant + BOARD_MCK_FREQUENCY. Also now supports methods to attach user + interrupt handlers (2014-8-9). + * drivers/audio/audio_null.c: Fix an error in a variable name + (2014-8-9). + * arch/arm/src/sama5/sam_oneshot.c, .h, Kconfig, Make.defs, sam_tc.c, + .h, and sam_adc.c: Add support for a one-shot timer wrapper around + the low-level timer/counter logic. This also involved several changes + that rippled into the ADC driver (untested) (2014-8-9). + * arch/arm/src/sama5/sam_freerun.c, .h, Kconfig, and Make.defs: Add + support for a free-running timer wrapper around the low-level + timer/counter logic (2014-8-9). + * arch/arm/Kconfig, src/sama5/sam_tickless.c, Kconfig, Make.defs: Use + the one-shot and free-running timers to implement tickless OS support + for SAMA5 (2014-8-9). + * arch/arm/src/sama5/sam_oneshot.c and sam_tc.c: Fix several bugs in + timer/counter interrupt logic and one-shot timer logic. Comments and + debug output updated in additional files (2014-8-10). + * sched/wdog/wd_start.c: Correct a bug in Tickless OS support: logic to + detect changes in head of timer list was wrong (2014-5-10). + * sched/sched/sched_timerexperation.c, sched.h, and wdog/wd_start.c: In + tickless mode, need to stop the interval timer before inserted a new + delay into the timer list. Otherwise, the time is incorrect on the + first entry of the list (2014-8-11). + * arch/arm/src/sama5/sam_freerun.c and sam_oneshot.c: Correct bad time + conversion, 1000000 not 1000 to convert seconds to microseconds + (2014-8-11). + * sched/sched/sched_timerexpiration.c: Fix inaccurate time conversion. + Remove MSEC_PER_TICK from calculation and convert uint32_t to uin64_t + (2014-8-11). + * libc/time/lib_localtime.c, private.h, tzfile.h and several header and + make-related files: Adds support for localtime. From Max Neklyudov + (2014-8-12) + +7.5 2014-09-28 Gregory Nutt + + * clock/clock_systimespec.c and sched/clock/clock_gettime.c: When + reading the system timer, don't read a struct timespec, convert it + to a fake tick count, then back to a timespec (2014-8-15). + * sched/clock/Make.defs, clock_gettime.c, clock_settime.c, include/time.h, + nuttx/clock.h, configs/vsn/src/sif.c: Remove CLOCK_ACTIVETIME. It is non- + standard, unused, and gets in the way of maintaining clocks (2014-8-15). + * libc/time/lib_localtime.c: Modified to that the coding style is much + closer to NuttX coding style. The local header files private.h and + tzfile.h were removed and incorporated into lib_localtime.c. All + conditional compilation within lib_localtime.c that unconditionally + evaluated to FALSE was removed (2014-8-15). + * drivers/net/Kconfig and include/nuttx/arch.h: Standardize a PHY + interrupt attachment interface (2014-8-16). + * configs/Kconfig, sama5d3-xplained, sama5d3x-ek, and sama5d4-ek: + Convert existing board specific PHY interrupt interfaces to use newly + defined standard interface (2014-8-16). + * include/net/slip.h: Move SLIP prototypes from net.h to slip.h + (2014-8-16). + * include/net/net.h and net/: Fix some missing function headers + (2014-8-16). + * drivers/net/phy_notify.c, include/nuttxarch.h, net/phy.h, and + ioctl.h: Add support for an ioctl that can be used to notify an + application when there is a change in the network status signalled + by a PHY interrupt (2014-8-16). + * drivers/net/phy_notify.c, include/net/if.h, ioctl.h, netdev.h, phy.h, + and net/netdev/netdev_ioctl.c: Finishes the ioctl definition to + subscribe to PHY events. Revamp network ioctl signature to support + arguments other than struct mii_ioctl_data (2014-8-16). + * arch/arm/src/stm32/stm32_eth.c: Modified to support the change to the + network ioctl signature changes.

That guess is often wrong. A better approach would be to + call strtol() directly on the input data, using the endptr return + value to determine how many characters to skip after parsing. From + Kosma Moczek (2014-8-18). + * net/arp/arp_dump.c: Add missing configuration option to select + dumping of ARP packet headers. Move ARP dumping logic from + arp_inout.c to its own file (2014-8-18). + * net/arp/arp_out.c: Move arp_out() from arp_inout.c to its own file + (2014-8-18). + * net/arp/arp_arpin.c: Move arp_arpin() from arp_inout.c to its own file + (2014-8-18). + * net/arp/arp_ipin.c: Rename arp_inout.c to arpipin.c because that is + all that is left in the file (2014-8-18). + * net/arp/arp_format.c: Move the logic that formats an ARP packet into a + separate file where it can be re-used. (2014-8-18). + * net/arp/arp_out.c and net/pkt/pkt_send.c: Change how the IFF_NOARP + flag is handled. This should be set only when data is moved into the + buffer and cleared after tested by the ARP logic. Setting it globally + can cause packets to be sent with no valid MAC addresses (2014-8-18). + * net/arp/arp_send.c: Partial implementation of logic to send ARP + requests to assure that an IP address mapping is present in the ARP + table (2014-8-18). + * net/arp/arp_poll.c: Finished the implementation of logic to send ARP + requests. Complete, fully hooked into the networking logic, and ready + for test (but still untested) (2014-8-18). + * net/icmp/icmp_ping.c, net/socket/net_sendfile.c, sendto.c, + net/tcp/tcp_send_buffered.c, and tcp_send_unbuffered.c: If + CONFIG_NET_ARP_SEND is enabled, then all ICMP, TCP, and UDP send + operations will call arp_send() before attempting the real send + operation. arp_send() will check if the IP address mapping is in + the ARP table and, if not send ARP requests periodically until it is. + This eliminates losing the first outgoing message because there is not + mapping in the ARP table (2014-8-18). + * net/arp/arp_notify.c, arp_send.c, arp_arpin.c, and arp.h: Add + signalling logic so that we do not have to wait so long with the + network responses to ARP requests quickly (2014-8-19). + * include/nuttx/lcd/ili9341.h: Add a register definition header file + for the ILI9341 LCD (2014-8-19). + * net/arp/Kconfig: ARP request logic is no longer EXPERIMENTAL + (2014-8-20). + * net/arp/arp_send.c: ARP request logic needs to do the right thing if + (1) the address is a broadcast or multicast address, and (2) if the + IP address lies outside of the network. Problem noted by Manuel Stuehn + (2014-8-20). + * configs/sam4e-ek/src/Kconfig and src/sam_ili9341.c: Add ILI9341-based + LCD driver.

I am not + certain if the granule allocator is sufficiently deterministic for + long range use, but it gets get a page allocator in place for testing + very quickly (2014-8-23). + * ARMv7-A: Add skeleton implementation and build support for process + address environments (2014-8-23). + * Many files: Change CONFIG_ADDRENV to CONFIG_ARCH_ADDRENV; change how + it is selected -- the architecture must first declare support + (2014-8-24). + * include/nuttx/addrenv.h, arch/arm/include/arch.h, armv7-a/irq.h, and + other files: Add addrenv.h; First cut at Cortex-A address environment + structures; Add configuration options to setup address environment + (2014-8-24). + * addrenv interface changes: up_addrenv_create() may need to create + .text and .bss/.data separately because of differing access privileges + (read/execute vs read/write). And, as a consequence, up_addrenv_vaddr() + needs to be split into up_addrenv_vtext() and up_addrenv_vdata(). + Affects several files (2014-8-24). + * arch/arm/src/armv7-a/arch_coherent_cache.c: New file. These cache + operations are called from the ELF loader in order to flush D-cache + and invalidate I-cache after an ELF module has been loaded into memory. + With this change, ELF modules work correctly on the SAMA5/Cortex-A + platform (2014-8-24). + * configs/sim: Add build support for ELF modules.

NuttX processes are now functional + on the Cortex-A (2014-9-11). + * arch/arm/src/armv7-a/arm_fullcontextrestore.S, arm_syscall.c, crt0.c, + and svcall.h: Modify up_fullcontextrestore() for CONFIG_BUILD_KERNEL. + It changed CPSR while in kernel. That will crash if the new CPSR is + user mode while executing in kernel space. Fixed by adding a + SYS_context_restore system call. There is an alternative, simpler + modification to up_fullcontextrestore() that could have been done: It + might have been possible to use the SPSR instead of the CPRSR and then + do an exception return from up_fullcontextrestore(). That would be + more efficient, but I never tried it (2014-9-12). + * binfmt/libelf/libelf_load.c: ELF: Critical bugfix.. BSS was not being + cleared (2014-9-12). + * configs/sama5d4-ek/knsh/defconfig and defconfig.ROMFS: Enable NSH + file applications in these configurations (2014-9-12). + * libc/Kconfig, unistd/lib_execsymtab.c, configs/sim/nsh/defconfig, and + stm32f4discovery/posix_spawn/defconfig: Having a symbol table is an + option.

Now that arguments are kept on + the stack, the way that arguments are passed from parent to child in + vfork() must change. This bug has always been present, but was not + visible with the old strdup() way of passing arguments (2014-9-29). + * arch/arm/src/common/up_vfork.c: Another vfork() problem: If we get to + vfork() via system call, then we need to clone some system call + information so that the return form the cloned system call works + correctly (2014-9-29). + * fs/mqueue: Move mq_open(), mq_close(), and mq_unlink() logic from + sched/mqueue to fs/mqueue. Convert the logic so that it uses the VFS to + managed the message queue namespace (instead of custom logic). By + default, now message queues can be seen in /var/mqueue (2014-9-29). + * arch/sim/src/up_simuart.c, up_uartwait.c: Removed old, strange + up_stdio.c and implemented a simulated UART driver to provide the + console input.

This is a necessary + piece of the support for asynchronous I/O (2014-10-10). + * sched/wqueue/work_inherit.c: Add logic for priority inheritance with + multiple worker threads. How should this work? Tentatively, the all + get reprioritized together. It would be best to just reprioritize the + single thread doing the high priority work, but we don't know which + that will be in advance (2014-10-10). + * fs/aio/ and include/aio.h: Add support for socket-based transfers + (2014-10-11). + * arch/arm/include/stm32/chip.h, /src/stm32/Kconfig, and + stm32_allocateheap.c: Support for the STM32 F411RE from Serg Podtynnyi + (2014-10-14). + * configs/Kconfig, README.txt, and nucleo-f401re: Extend this board + configuration to also support the Nucleo-F411RE.

Add + data structures and logic to handler different TCP receive windows + when both Ethernet and SLIP are enabled (2014-11-16). + * configs/sama5d4-ek/bridge: Add a simple test for the dual EMACs on + the SAMA5D4 (2014-11-17). + * arch/arm/src/sama5/sam_emacb.c: Fix several typos that will prevent + EMAC1 from initializing properly (2014-11-17). + * include/nuttx/net/ip.h and tcp.h, net/icmp/icmp_send.c and + igmp/igmp_send.c: Move IP header flags from tcp.h to ip.h and rename + IP_FLAGS vs TCPFLAGS. The problem fixed here is that there IP flags + were not available when TCP was disabled. The IP flags are used in + ICMP and IGMP (2014-11-17). + * sched/clock/clock_abstime2ticks.c: Calling mq_timedreceived() with + immediate timeout was getting stuck and not timing out. Immediate + timeout is achieved by setting absolute timeout value to past time, + for example abstime={ .tv_sec=0, .tv_nsec=0 }. However absolute + time was converted to relative time using unsigned integer arithmetic + and resulted large ticks count by clock_abstime2ticks, instead of + expected negative ticks value. Change corrects clock_abstime2ticks() + to return negative ticks, if absolute time is in the past. From + Jussi Kivilinna (2014-11-19). + * fs/vfs/fs_poll.c: poll() was not waking up from signals (for example + mq_notify() events).

From Pierre-noel Bouteville (2014-11-27). + * drivers/wireless/ and include/nuttx/wireless/cc3000.h: A set of 11 + patches correcting issues with the CC3000 networking. All from Jussi + Kivilinna (2014-11-28). Among these: + 03/11: CC3000 driver was getting stuck at recv() when remote host + closed connection and application tried to read data from remotely + shutdown socket. This patch adds proper handling for remotely closed + socket event. + 07/11: Socket state initialization was done in 'register', while it + should be initialized in 'open' and deinitialized in 'close'. Old + way caused problems when device is closed, power-cycled and then + reopened as old socket state was left enabled. + 08/11: Select thread was getting stuck after 'close, power-cycle, + reopen', since selectsem was not properly setup and cleaned up. + 09/11: 'maxFD' was not properly reset in select worker and not checked + for before calling cc3000_select(). + 10/11: After wlan_stop()/cc3000_close(), irqsem was left with count + '-1'. Therefore on next wlan_start()/cc3000_open(), initial value + for irqsem was wrong. Additional repeated wlan_start()/wlan_stop() + decreased irqsem value further. Obviously this causes driver not to + function correctly and freeze. Patch moves initialization and + destruction of waitsem, irqsem and readysem to + cc3000_open/cc3000_close. + * include/cxx/cctype: Undefine macros defined ctype.h so that builtin + C++ implementations will be used intead.

The + ioctl() interface is a non-standard, Unix interface. NuttX has always + used the older, three-parameter version. Most contemporary systems + now, however, use a variadic form of the ioctl() function. Added an + option to insert a shim layer to adapt the three-parameter ioctl() to + use the variadic interface form. Internally, the ioctl handling is + the same three-parameter logic. The only real complexity to the shim + is in how the system calls must be handled (2014-11-29). + * arch/arm/src/stm32/stm32_i2c.c: Port Tridge's I2C noise resilience + logic from the PX4 repository (2014-11-29). + * arch/arm/src/stm32/chip/stm32l15xxx_pinmap.h: Fix a typo in the + MCO pin definition.

Discovered and fixed by Sebastien Lorquet after much + consternation (2014-12-8). + * libc/stdio/lib_avsprintf.c: avsprintf(): Fix a bug in usage of + va_list on x86. On x86, va_list is a pointer to a single copy on the + stack. avsprintf() calls lib_vsprintf() twice and so traverses the + va_list twice using va_start. va_start modifies that single copy on + the stack so that the second call to lib_vsprintf() fails. This appears + to be an issue with x86 only so far (2014-12-8). + * stdint.h: Don't use hex values to specify minimum values of fixed + width, signed values. Hex values are inherently unsigned and not + usable for this purpose in all contexts (2014-12-8). + * arch/arm/src/tiva/tiva_i2c.c, tiva_i2c.h, Kconfig, and Make.defs: Add + build framework and skeleton files for Tiva I2C driver.

If Both ULPI + and the FS clock enable bits are set in FS mode, then the ARM never + awakens from WFI due to a chip issue. This is only an issue if you + are using the internal PHY. From Ken Pettit (2014-12-13). + * drivers/serial/serial.c: In case a thread is doing a blocking + operation (e.g. read()) on a serial device, while it is being + terminated by pthread_cancel(), then uart_close() gets called, but + the semaphore (dev->recv.sem in the above example) is still blocked. + This means that once the serial device is opened next time, data will + arrive on the serial port (and driver interrupts handled as normal), + but the received characters never arrive in the reader thread. + The problem was fixed by re-initializing the semaphores on the last + uart_close() on the device. From Harald Welte (2014-12-13). + * sched/semaphore/sem_recover.c, Make.defs, seamphore.c, + sched/wdog/wd_recover.c, Make.defs, wdog.h, sched/task/task_recover.c: + Add logic to clean up after task_delete() or pthread_cancel() if the + task happens to be waiting on a semaphore when it is cancelled + (2014-12-13). + * arch/arm/src/kl/kl_gpioirq.c, Kconfig, Make.defs, and kl_irq.c: Add + GPIO interrupt capability for the KL architecture.

From Alan + Carvalho de Assis (2014-12-16). + * configs/freedom-kl25z: Add board support for the ADXL345 accelerometer. + From Alan Carvalho de Assis (2014-12-16). + * Kconfig, include/debug.h, drivers/sensors/*, and Qencoder logic in + arch/arm/src/stm32 and various QEncoder board support files under + config/: Unify sensor debug. ADX driver was using input debug; LM75 + and QENCODE that their own custom debug. Now all use + CONFIG_DEBUG_SENSOR, sndbg() (2014-12-16). + * configs/dk-tm4c129x: Initial board support for the Tiva DK-TM4C129x + Connected Development Kit.

The previous logic used a busy-wait loop + to poll the card R1 status to determine when the card was ready for + the next transfer. That busy-wait can be quite long -- up to hundreds + of milliseconds. An alternative is to look the SD D0 pin which + will change state when the card is no longer busy. This change avoids + the busy-wait poll by reconfiguring the SD D0 pin as a GPIO interrupt, + then waiting for the card to become ready without taking up CPU + cycles. This change is conditioned on CONFIG_MMCSD_SDIOWATI_WRCOMPLETE + and is currently only implemented for the STM32 SDIO driver. From + David Sidrane (2015-01-08). + * arch/arm/src/tiva/tiva_timerlib.c and .h: Add a timer library for + generic support of Tiva timers (2015-01-08). + * arch/arm/src/tiva/tiva_timerlow32.c: Add a driver lower half for + drivers/timer.c. Only 32-bit periodic timers are supported. This + provides userspace access to timers. + * configs/px4-v2_upstream, Kconfig, README.txt: Remove the px4-v2_upstream + configuration. Moved to misc/Obsoleted/configs. This was not the + official configuration for the PX4 board and has led to confusion by + NuttX users. The board configuration also requires some ongoing + maintenance and customization to support ongoing PX4 testing and + evaluation.

From Liio Chen via the PX4 repository + (2015-01-27). + * arch/arm/src/stm32/stm32_exti_gpio.c: Disabling any of EXTI 5-9 + interrupts was disabling interrupts for all EXTI 5-9. Same issue with + EXTI 10-15. From Jussi Kivilinna (2015-01-27). + * arch/arm/src/stm32/stm32_rtcc.c and Kconfig: Recent changes to + stm32_rtcc.c do not compile with STM32L15XX configurations. From + Jussi Kivilinna (2015-01-27). + * net/local: Add initial support for local, Unix domain sockets. + Initial support is limited to SOCK_STREAM and is untested on + initial commit (2014-01-27). + * net/iob, net/tcp/tcp_callback.c, and include/nuttx/net/iob.h: There + were issues with the TCP write-ahead buffering if CONFIG_NET_NOINTS was + enabled: There is a possibility of deadlocks in certain timing conditions. + I have not seen this with the Tiva driver that I have been users but + other people claim to see the issue on other platforms. Certainly it + is a logic error: The network should never wait for TCP read-ahead + buffering space to be available. It should drop the packets + immediately. This was fixed by duplicating most of the IOB interfaces: + The versions that waited are still present (like iob_alloc()), but now + there are non-waiting versions of the same interfaces (like + iob_tryalloc()). The TCP read-ahead logic now uses only these non- + waiting interfaces (2015-01-27). + * net/tcp/tcp_send_buffered.c and tcp_wrbuffer.c: Fix another deadlock + condition. tcp_write_buffer_alloc() calls sem_wait() with network + locked. That worked if CONFIG_NET_NOINTS was not defined because + interrupts are automatically restored when the wait happens. But + with CONFIG_NET_NOINTS=y, the wait blocks with the network locked -- + bad style and also can lead to a deadlock condition (2015-01-28). + * arch/arm/src/armv7-a/arm_memcpy.S and arch/arm/src/armv7-m/up_memcpy.S: + ARM assembly language memcpy.S's were not returning a value in R0 they + are required to do. From David Sidrane (2015-01-29). + * net/local: Extend Unix domain socket support to include support + for datagram Unix domain sockets (2015-01-29). + * net/socket/accept.c: Fix a major TCP bug introduced with commit + e71c09ce9777ff732cb60bd07fb43d85522f79d6. Some connection logic was + reordered; setting the socket as 'connected' got moved to BEFORE the point + where the check was made if the socket was already connected. The + resulting behavior was odd: Telnet would connect, but then when you + exit and reconnect, it would fail to connect. But then if try again, it + would connect okay. So the symptom was connect-fail-connect-fail-... + (2015-01-29). + * net/socket/net_poll.c, recvfrom.c, and udp/udp_callback.c: Add UDP + read-ahead support. This enables support for for poll/select on UDP + sockets and also non-blocking UDP sockets. From Macs N (2015-01-30). + * net/local/local_netpoll.c, socket/net_poll.c, and udp/udp_netpoll.c: + Separate out UDP poll logic from net_poll.c into a new udp_netpoll.c; + Create a skeleton local_netpoll (2015-01-30). + * net/socket/net_poll.c and tcp/tcp_netpoll.c: Separate TCP poll logic + out of net_poll.c and move it into the new tcp_netpoll.c (2015-01-30). + * arch/arm/src/efm32/efm32_clockconfig.c: Logic to unconditionally enable + LE clocking. Even you don't use core clock LE as source for LFA or LFB, + to read are write any register not clocked by HFPERCLK or HFCORECLK, + HFCORECLKLE should be enabled. From Pierre-noel Bouteville (2015-01-30). + * drivers/net/slip.c: SLIP interface improvements. From Macs N + (2015-01-30). + * clock_systimespec(): Fixes for compilation errors in certain + configurations. From Macs N. + * drivers/pipes/fifo.c, include/nuttx/fs/ioctl.h, and net/local/local_fifo.c: + Fix a race condition between FIFO buffer operations and the opening and + closing of FIFOs which necessary when the FIFOs are used to support + Unix domain, datagram sockets. The default policy is the deallocate + FIFO buffering when the last client closes the pipe. When when used + for datagram communications, packets left in the FIFO will be lost. + Some like UDP read-ahead is needed: The buffered data in the FIFO + needs to be retained until the reader gets a chance to re-open the + FIFO. Added an ioctl (PIPEIOC_POLICY) to control the buffer policy. + Default (0) is the legacy behavior; Unix domain datagram logic sets + the alternative policy so that the packet data persists after the FIFO + is closed (2015-01-30). + * net/local: Add configuration options so that Unix domain stream and + datagram support can be separately enabled (2015-01-31). + * fs/vfs/fs_unlink.c and include/nuttx/fs/fs.h: Add an unlink method to + both the character and block driver interface. This is important + because if the driver inode is unlinked and there are no open references + to the driver, then the driver resources will be stranded. On the unlink + call, the driver has the opportunity (1) check if there an any open + references, and if not, (2) free the driver resources (2015-01-31). + * drivers/pipes: Implement the unlink method. If the pipe/FIFO is + unlinked, it will marked the pipe/FIFO as unlinked. If/when all open + references to the driver are closed, all of the driver resources will + be freed (2015-01-31). + * arch/avr: Added architecture support for the Atmel AVR ATMega1284P + MCU. From Jedi Tek'Unum (2015-01-31). + * configs/moteino-mega: Added support for the LowPowerLab MoteinoMEGA + that is based on the Atmel AVR ATMega1284P MCU. From Jedi Tek'Unum + (2015-01-31). + * EFM32 RTC: RTC driver using BURTC. From Pierre-Noel Bouteville + (2015-02-01). + * drivers/ramdisk.c, include/nuttx/fs/ramdisk.h, and other files: Add + logic to dispose of the driver and RAM buffer when the RAM disk has + been unlinked and all open references to the RAM disk have been + closed. Add new parameters to romdisk() to specify what should be + done with the RAM/ROM buffer -- Should it be freed or not? Changed + all calls to ramdisk() to use these new parameters (2015-02-01). + * net/icmpv6/icmpv6_neighbor.c, icmpv6_notify.c (and other files): Adds + basic logic to support verification that we have the IPv6 address in + the Neighbor Table. This feature is important because otherwise the + first packet sent to a remote peer will fail (it will be replaced + with a Neighbor Solicitation) (2015-01-02). + * net/arp/arp.h, arp_notify.c, and arp_send.c: Fixes another + CONFIG_NET_NOINTS issues. When called sem_timedwait() with the + network locked, the network stays locked while we wait which is not + what we want (without CONFIG_NET_NOINTS, interrupts are re-enabled + while we wait and all is well) (2015-02-02). + * net/icmpv6/icmpv6.h, icmpv6_neighbor.c, icmpv6_notify.c: Apply the + same fix as for ARP to the Neighbor Solicitation logic (2015-02-02). + * sched/sched/sched_timerexpiration.c, Kconfig, and include/nuttx/arch.h: + On my platform I have just 16-bit timer clocked at 32kHz. As result + oneshot timer max delay is 2s. The patch adds limit of maximum ticks + in sched_timer_start(). From Macs N (2015-02-03). + * arch/arm/src/sam34: Add support for Tickless mode of operation for + the SAM4CM platform. From Macs N (2015-02-03). + * include/nuttx/net/icmpv6.h and net/icmpv6/Kconfig: Add support for + sending ICMPv6 Router Solicitation and receiving Router advertisement. + This is a part of the ICMPv6 auto-configuration logic is still not + complete (2015-02-03). + * libnx/nxfonts/nxfonts_getfont.c and nxfonts_sans39x48.h: Fixes a + problem with one of the font files.

This is the driver + that is documented in include/nutt/rtc.h (2015-02-13). + * arch/arm/src/stm32/stm32_rtcc.c and stm32_rtc.h: Break out a new internal + interface, stm32_rtc_setdatetime(). This eliminates some un-necessary + time conversions. From Freddie Chopin (2015-02-13). + * arch/arm/src/stm32/stm32_rtc_lowerhalf.c, Make.defs, and stm32_rtc.h: Add + a skeleton implementation of the RTC lower half interface at + arch/arm/src/stm32/stm32_rtc_lowerhalf.c. This is just the framework for + the RTC lower half. None of the interface methods have yet been + implemented (2015-02-13). + * net/icmpv6/icmpv6_advertise.c and icmpv6_solicit.c: Add inclusion of + nuttx/net.h to two files. Without these there can be compilation errors + in certain configurations. From Max Neklyudov (2015-02-13). + * net/net_initialize.c, sched/init/os_start.c, and a few other files: + Divide net_intiialize() into net_setup() and net_initialize() to solve + a chicken-and-egg problem. net_setup() must be called before + up_initialize() is called so that networking data structures are ready + to register new network devices. net_initialize() now does only timer + related operations and is called AFTER up_initialize() where the timers + are configured. Problem note by Max Neklyudov (2015-02-14). + * include/time.h and sys/time.h: Move struct timeval from include/time.h + to include/sys/time.h where it belongs (2015-02-15). + * arch/arm/src/stm32/stm32_rtcc.c, stm32_rtc.h, and Kconfig: Extend the + RTC interface to support reading subseconds.

From Pierre-noel Bouteville (2015-02-16). + * include/nuttx/net/ip.h: Move macros and common logic for IPv4-mapped + IPv6 addresses from files in net/ to include/nuttx/ip.h. These are + currently only used for UDP, but will need to be be used in many places + in the future (2015-02-17). + * includes/nuttx/compiler.h: Add support for the restrict keyword + (2015-02-17). + * include/netdb.h: Add a mostly-commented-out version of the standard + netdb.h header file (2015-02-17). + * arch/arm/src/tiva/: Updated files to allow for ADC triggering by the + timer. I’ve cleaned up some parts of the ADC code, too, and fleshed + out the PWM triggering ioctl. From Calvin Maguranis (2015-02-17). + * configs/tm4c123g-launchpad: Add ADC support. From Calvin Maguranis + (2015-02-17). + * fs/fat/fs_mkfatfs.c: Use DMA memory for mkfatfs when needed. This makes + mkfatfs use fat_dma_alloc() when CONFIG_FAT_DMAMEMORY is set. This is + needed to ensure mkfatfs operates with boards that use DMA for microSD. + From Andrew Tridgell via the PX4/NuttX repository (2015-02-17). + * include/nuttx/rtc.h, fs/fs.h, drivers/ramdisk.c, pipes/, and + timers/rtc.c: The inode unlink method should not be support if + operations on the root pseudo-filesystem are disabled (2015-02-18). + * include/nuttx/sched timing functions: Fix some nanosecond comparisons. + Comparisons should be greate than OR EQUAL TO 1000000000 for maximum + value of nanoseconds in struct tm.

Make sure that it builds + using the Pinquino toolchain (2015-02-21). + * arch/mips/src/mips32/Toolchain.mk: Current Pinguino toolchain uses + the prefix p32- instead of mips- (2015-02-21). + * configs/pic32mz-starterkit: Add basic board support for the PIC32MZ + (can't build yet of course because there is not yet any PIC32MZ + support) (2015-02-22). + * arch/mips/src/pic32mz and include/pic32mz: Add some PIC32MZ header + file definitions and just enough logic in the source directory so + that we can run 'make menuconfig'. Still a very long way from being + complete (2015-02-22). + * libc/time/lib/lib_sfrtime.c: Missing implementation of %C in + sfrtime() C (was being treated as %y). From Freddie Chopin + (2015-02-23). + * drivers/can.c: In the can_open function: this line + 'dev->cd_ocount = tmp;' needs to be moved a few lines down otherwise + the open count will only be incremented from 0 to 1. This causes + problems when trying to open the can bus from two different tasks. + SourceForge Patch #46 from Anonymous (2015-02-23). + * Tiva TM4c1294: Updates from Frank Sautter (2015-02-24). + * fs/aio: correct some backward tests in aio_read() and aio_write(): + Socket descriptors have higher numbers than file descriptors.

From + Dmitry Nikolaev via Jussi Kivilinna (2015-03-13). + * arch/arm/src/efm32/efm32_i2c.c: Add I2C driver. From Pierre-noel + Bouteville (2015-03-14). + * fs/mount/, include.sys/mount, syscall/: Add umount2(). umount() is + now a macro that just calls umount2() with flags = 0 (2015-03-14). + * fs/mount/fs_umount2.c, all file systems, include/nuttx/fs/fs.h: Pass + the umount2() flags to every unbind() implementation. That is where + the decision to umount or not will be made (2015-03-14). + * fs/fat/fs_fat32.c: Fix a bug in the FAT unbind() logic. There were + problems with the way certain internal list handling was implemented. + The end result is that newly opened or cloned file structures were + never being added to the list of open files. So when the unmount() + happens, it always looked like there were not open files and a crash + could ensue (2015-03-14). + * fs/fat/fs_fat32.c and fs_fat32.h: Add support for umount2(target, + MNT_FORCE) in the FAT file system (2015-03-15). + * drivers/mmcsd/mmcsd_sdio.c: Fix some bad logic when file system debug + is turned on: Arguments to syslog were missing so that garbage was + being printed (2015-03-15). + * arch/arm/src/sama5/sam_hsmci.c: Fix a bug in SAMA5 HSMCI. The + bitfield mask and shift values were reversed resulting in a trashed + value for the number of blocks in the BLOCKR register. This was + sufficient to prevent DMA writes from working (2015-03-15). + * drivers/mtd/at24xx.c, Kconfig, and include/nuttx/fs/ioctl.h: Add + support for (1) the byte-oriented read() method, (2) devices that + have extended memory regions, and (3) devices that use 8-bit + addressing (2015-03-17). + * arch/mips/src/mips32/Kconfig, Toolchain.defs, and + configs/pic32mz-starterkit/nsh/Make.defs: Changes that will permit + building of the PIC32MZ Start Kit configuration using MPLAB and the + XC32 toolchain. From David Sidrane (2015-03-17). + * arch/arm/src/stm32/stm32_rtc_lowerhalf.c: Fix some errors in the + STM32 RTC lower-half driver that cause compilation failures.

From Bob Doiron (2015-03-20). + * configs/olimexino-stm32: Board support for the Olimexino STM32 board + from David Sidrane (2015-03-20). + * PIC32MZ: Incorporated a set of patches that makes the basic NSH + configuration on the PIC32MZ Starter Kit. From Kristopher Tate + (2015-03-22). + * arch/arm/src/tiva: (1) ADC driver has been re-organized; configuration + is now handled in code instead of Kconfig to help reduce bloat and + confusion. (2) Timer changed to remove ADC coupling in Kconfig to code + and moved configuration up from arch/arm/src/tiva to + configs/tm4c123g-launchpad/src. (3) GPIO driver needed small fixes in + the configuration routines and discovered false-positive bugs in + interrupt testing: interrupts are now verified to actually be working + reliably. (4) Attempt to apply some consistency in the tiva arch/ + level's interface to the config/board/ level driver configuration. + From Calvin Maguranis (2015-03-23). + * arch/mips/src/pic32mz: Various fixes for Ethernet support. Still + not fully functional. From Kristopher Tate (2015-030-29). + * arch/arm/src/armv7-m: Add configuration option and logic to support + the D-Cache in write-through mode (2015-03-29). + * arch/arm/src/stm32/Kconfig, stm32_lse.c, stm32_lsi.c, stm32_rtc.c/.h, + stm32_rtcc.c, stm32_rtcounter.c, and stm32f*_rcc.c: The + STM32F4Discovery board doesn't come with a Low speed external + oscillator so the default LSE source for the RTC doesn't work. In + stm32_rtcc.c the up_rtc_initialize() logic doesn't work with the LSI. + The check on RTC_MAGIC on the BK0R register lead to rtc_setup() call + that rightfully enables the lsi clock; but the next times, when the + rtc is already setup, the rtc_resume() call does NOT start the lsi + clock! The right place to put LSE/LSI initialization is inside + stm32_stdclockconfig() in stm32fxxxxx_rcc.c. Doing this I checked + the possible uses of the LSI and the LSE sources: the LSI can be used + for RTC and/or the IWDG, while the LSE only for the RTC (and to output + the MCO1 pin). This change is not verifed for any other platforms. + From Leo Aloe3132 + * Rename arch_nshinitialize() to board_app_initialize() (2015-03-30). + * ./*.mk, configs/.gitignore, Makefile, boardctl.c, include/nuttx/fs/ioctl, + include/sys/boardctl.h, syscall.h, and syscall/: Add a new non- + standard OS interface called boardctl(). This is similar to a driver + IOCTL call. But this is an IOCTL call directly on the board logic. + This function will eventually replace all of the ad hoc OS interfaces + that are current used to perform application specific initialization + and application driver test configuration. It essentially formalizes + and institutionalizes these rogue interface in to at least a single + crazy call (2015-03-31). + * configs/: Modify all configurations: Make sure that + CONFIG_LIB_BOARDCTL=y appears wherever CONFIG_NSH_ARCHINIT=y appears. + Remove support for CONFIG_NSH_ARCHMAC. It is not used and there are + better ways to do that operation (2015-03-31). + * configs/Kconfig, boardctl.c, all touchscreen driver setup functions, + include/board.h, include/sys/boardctl.h, and + include/nuttx/input/touchscreen.h: arch_tcinitialize() and + arch_tcunitinitialize() renamed to board_tsc_setup() and + board_tsc_teardown(). These are not long called directly by + applications but only indirectly throught the crappy boardctl() OS + interface (2015-03-31). + * configs/Kconfig, boardctl.c, include/nuttx/board.h, include/sys/boardctl.h, + and several ADC files in configs//src/: Rename adc_devinit() to + board_adc_setup(). Add support to the boardctl() interface so that it + can call board_adc_setup() on behalf of an application. Make sure that + the proper features are enabled in the defconfig files that have + CONFIG_EXAMPLES_ADC=y (2015-03-31). + * configs/*/defconfig: Make sure that all defconfig files that require + external graphics intiialization also enable the correct boarctl() + settings (2015-03-31). + * include/nuttx/board.h, include/sys/boardctl.h, nuttx/configs/Kconfig and + boardctl.c, and board configurations and PWM implementations: Rename + pwm_devinit() to board_pwm_setup(). Add CONFIG_BOARDCTL_PWMTEST that + will enable calling board_pwm_setup() from boardctl(). In all + configurations that enable the apps/examples/pwm test, make sure that + boardctl() support is properly enabled (2015-03-31). + * Move include/nuttx/timer.h, rtc.h and watchdog.h to include/nuttx/timers/. + (2015-04-01). + * drivers/timer/cs2100-cp.c and include/nuttx/timers/cs2100-cp.h: Add a + very basic driver for the CS2100-CP Fractional-N Multipler chip (2015-04-02). + * configs/, graphics/, include/nuttx: More renaming: up_lcdinitialize->board_lcd_initialize, + up_lcdgetdev->board_lcd_getdev, up_lcduninitialize->board_lcd_uninitialize + (2015-04-04). + * include/nuttx/nx, libnx/nx, libnx/nxtk: Add a new 'capped' parameter to + nx_drawline(), nxtk_drawlinetoolbar(), and nxtk_drawlinewindow() + (2015-04-05). + * libnx/nx/nx_drawline.c, libnx/nxtk/nxtk_drawlinetoolbar.c and + nxtk_drawlinewindow.c: Implement line caps by drawing a file circle at + the each endpoint of a line with a radius equal to half of the width + of the line (2015-04-05). + * include/time.h, nuttx/time.h, libc/time/lib_dayofweek.c and + lib_gmtimer.c: Implements CONFIG_TIME_EXTENDED as we discussed + relative to providing the last 3 members of the tm struct and support + for filling them in and even using the wday in the STM32 RTC. From + David Sidrane. + * arch/arm/src/sam34/sam_serial.c and samv7/sam_serial.c: A side-effect + of changing serial settings via TERMIOS (such as tcsetattr) is that + serial interrupts were being left disabled. This is not a problem if + the serial configuration is changed when there are no open references + to the serial device. In that case, serial interrupts are disabled and + will not be enabled enabled until the serial device is first opened. + But it is fatal if the serial device is already opened and if there is + a task waiting to receive data. In that case, the side-effect of + disabling interrupts is fatal: That task is then left hanging with + interrupts disabled (2015-04-08) + * arch/arm/src/sama5/sam_serial.c: Backport support for flowcontrol and + termios from SAM3/4 -- UNVERIFIED. (2015-04-08). + * arch/arm/src/sam34/sam_serial.c and samv7/sam_serial.c: The IMR + register is read-only. This means that sam_restoreints() did not + actually re-enable UART interrupts (2015-04-08). + * sigaddset() and sigdelset(): Need to set errno if a bad signal number + is received (2015-04-09). + * sighold(), sigrelse(), sigignore(), sigset() and sigpause(): New + signal handling functions (2015-04-09). + * Fixes to asinh(), atanh(), and sinh(): The 'basic' expansions all + exhibited bad cancellation errors near zero (<= 1E-10). This can be + easily seen e.g. with x = 1E-30, the results are all zero though they + should be extremely close to x. The cutoff values (1E-5, 1E-9) are + chosen so that the next term in the Taylor series is negligible (for + double). Functions could maybe be optimized to use only first term (x) + and a smaller cutoff, just bigger than where the cancellation occurs + (2015-04-09). + * syscall/syscall.csv: Last changes to message queue prototypes did not + make it into call gate logic (2015-04-09). + * syscall/syscall_stublookup.c: Fix some errors that crept in recently + (2015-04-09). + * libc/time/lib_localtime.c: Inconsistent configuration name: + CONFIG_LIBC_TZDIR vs CONFIG_LIBC_TZ_TZDIR. Former wins (2015-04-11). + * libc/time/lib_calendar2utc.c and lib_mktime.c: Fix an error in time + initialization when there is not RTC and the time is initialized from + a fixed configured value. The call to clock_calendar2utc() was + returning the time in units of seconds. The initialization logic, + however, was expecting to get time in units of days. This problem + has been there forever but obviously has not significant impact to + behavior in systems where time is not visible (2015-04-12). + * fs/fat/fs_fat32utils.c: Fix misthink when CONFIG_ENDIAN_BIG=y. From + Lwazi Dube (2015-04-12). + * include/nuttx/net/netdev.h, net/devif/ipv6_input.c, + icmpv6/icmpv6_rsolicit.c and net/icmpv6/icmpv6_solicit.c: Use common + macro(s) for calculating link layer header length. From Brennan + Ashton (2015-04-13). + * apps/netutils/pppd/Kconfig, pppd.c, and ntpv3.h (removed): Remove + ntpclient header file in and NTP client references from the pppd + dir. From Brennan Ashton (2015-04-13). + * configs/galileo: Remove all references to the Galileo board.

LTDC only controls the + display visibility but the DMA2D controller changes the content of the + frame buffer (buffer of the layer). + + The main features are: + + 1. DMA2D interface + Supports the nuttx pixel formats: + - FB_FMT_RGB8 + - FB_FMT_RGB24 + - FB_FMT_RGB16_565 + Dynamic layer allocation during runtime for the supported formats + - The number of allocatable layer can be configured. + Supported dma2d operation: + - blit (Copy content from source to destination layer) also works + with selectable area. + - blend (Blend two layer and copy the result to a destination layer + which canbe a third layer or one of the source layer) also works + awith selectablerea. + - fillarea (Fill a defined area of the whole layer with a specific + color) + + As a result of that the dma2d controller can't transfer data from the + core coupled memory, CCM is disabled but usable by the ccm allocator. + Currently the ccm allocator is used for allocating the layer structure + only. For the dma memory (layers frame buffer) memory is allocated from + heap 2 and 3. + + 2. LTDC interface + I have changed the api for the currently non implemented operations: + - blit (Copy content from a dma2d layer to an ltdc layer) also works with + selectable area. + - blend (Blend two dma2d layer and copy the result to a destination ltdc + layer) also works with selectable area. + + Note! ltdc layer is a layer referenced by the ltdc interface. dma2d layer + is a layer referenced by the dma2d interface. + + One of the most important questions for me was, How can i flexible use an + ltdc layer with the dma2d interface, e.g. as source layer for dma2d + operations? + Get the layer id of the related dma2d layer by a special flag when using + getlid() function of the ltdc interface and use the layer id to reference + the specific dma2d layer by the dma2d interface. + + The ltdc coupled dma2d layers are predefined and can't be dynamically + allocated of freed. They use the same frame buffer memory and the same + color lookup table. + + Changes: + - layer internal format of the clut table + - interrupt handling for register reload (vertical vblank) instead using + waiting loop + - small fixes and refactoring + From Marco Krahl (2015-04-16). + * Add support for the new DMA2D features to the STM32F429i-Disco LTDC + configuration.

Needed + by Sbastien Lorquet (2015-05-26). + * SAM4CM and SAMA5D Free-running timer: Logic that samples the free + running counter reads the pending interrupt status register and + can cause interrupts to be lost. So, if when the status register + is read, the logic must also handle the timer overflow event. + Found and fixed by Max Neklyudov (2015-05-26). + * arch/arm/include/kinetis and arch/arm/src/kinetis: Basic support + for the Kinetis K20 architecture. Taken from PX4. This is the + work of Jakob Odersky (2015-05-26). + * net/: Move some ICMP event lists to the device structure. That + allows for both device-specific event processing and also devices + to generate events like network down. From Max Neklyudov (2015-05-27). + * net/: Extend Macs logic to ARP and ICMPv6. Also found and fix + several IPv6-related compilation errors that have crept in. IPv6 + has been broken for awhile (2015-05-27). + * net/tcp: Fix an important TCP networking bug: 16-bit flags was + being converted to 8-bits in a few locations, causing loss of + status indications (2015-05-27). + * net/socket and net/tcp: net_startmonitor.c always returned OK. In + the case where a socket has already been closed, it correctly handled + the disconnection event but still returned OK. Returning OK caused + the callers of net_startmonitor to assume that the connection was + okay, undoing the good things that net_startmonitor did and causing + the socket to be marked as connected. This behavior was noted by + Pelle Windestam (2015-05-28). + * include/nuttx/net, net/arp, net/devif, net/icmp, net/icmpv6, + net/netdev, net/pkt, net/tcp, net/udp: Modify event list handling: + Now there are two event lists each device structure: (1) One is + for ARP and ICMP data related events, the other is for device + related events. Callback allocation/free routines no accept a + device parameter as well as a list: If the device parameter is + added, then the callback goes into both the connection-related + list AND the device event list. Thus each socket type can + received both custom data-related events as well as common + device related events (2015-05-28). + * net/socket and net/utils: setsockopt() fails when setting timeouts + to values less that an 100 msec. That is because the timeout is + limited to stops of 1 decisecond and because the conversion of + structure timeval was truncating the microsecond remainder. The + utility net_timeval2dsec now accepts and option to determine how it + handles the remainder: truncate, discarding the remainder, use the + remainder to round to the closed decisecond value, or use any non-zero + remainder to the next larger whole decisecond value. Bug discovered + by Librae (2015-05-29). + * configs/stm32f4discovery/src: Move up_cxxinitialize from + nuttx/configs/stm32f4discovery/src to apps/platform/stm32f4discovery + where it belongs (2015-05-29). + * net/sockets, net/tcp, net/udp: UDP Networking: Add support for + device event notification for UDP transfers (2015-05-29). + * net/sockets and net/tcp: TCP Networking: Add support for device event + notification for UDP transfers (2015-05-30). + * libc/Kconfig and stdio/lib_libvsprintf.c: Add an option to disable + support for long long formats in lib_vsprintf. From Alan Carvalho + de Assis (2015-05-30). + * net/net_initialize.c, net/detdev, and net/socket: The network device + list was protected by a re-entrant semaphore. With the recent change + to support network device callback, the network stack needs to access + the network device list too. Some drivers, however, run the network + stack from the interrupt level -- this is bad but a fact in the + current state. Of course, those drivers are unable to take the + semaphore and would assert. + The solution here is to eliminate the device devices semaphore + altogether. This eliminates netdev_semtake() and netdev_semgive() + and replace them with net_lock() and net_unlock() which have the + larger scope that is needed and will integrate properly with the + dinosaur interrupt driven stack (2015-05-31). + * net/socket/connect.c: In the TCP connection operation, it was trying + to setup the network monitor BEFORE the socket was successfully + connected. This, of course, has ALWAYS failed because the socket is + not yet connected and the TCP state is not yet correct for a connected + socket. However, because of other changes net_startmonitor() now + returns a failure condition that causes worse problems when trying to + connect. The fix is to move the logic that starts the network monitor + to AFTER the socket has been successfully connected (2015-05-31). + * tools/configure.c: Fix test for the existence of the apps/ directory. + Fix backward interpretation of options, -l was selecting Windows and + -w was selecting Linux. This was SourceForege Ticket #39 (2015-05-31). + * arch/include/stm32/chip.h and arch/src/stm32/Kconfig: Add basic + support for the STM32F205RG.

Also + removed conditional logic form non-SAM4CM parts (Gregory Nutt) + (2015-06-22). + * SAM3/4: Add a TWI driver for the SAM4CM. From Max Neklyudov + (2015-06-22). + * SAMV7 Xplained: In clock configuration, divider was set to 25 to get + 25*12MHz=300MHz CPU clock. The correct multiplier is 24 because the + calculation if (24+1)*12MHz. So the board was running at 312MHz. + From Efim Monjak (2015-06-26). + * NFS client: Fix prototype of unbind method. The function prototype + was not updated for NFS after a recent change to the file system + interface.

Replaced with a GIT submodule + that will bring in the new standalone boards directory (2015-06-29). + * arch/arm/src/armv6-m/up_exception.S: Fix Cortex-M0 assembly error + when the interrupt stack is enabled. From Alan Carvalho de Assis + (2015-06-30). + * arch/arm/src/armv6-m/up_assert.c: Port some per-process stack + dumping logic from ARMv7-M to ARMv6-M. From Alan Carvalho de Assis + (2015-06-30). + * tools/testbuild.sh: Add a script that can be used to perform + building testing for several board configurations (2015-06-30). + * sched/pthread/pthread_create.c: Group binding needs to be cleared + before sched_releasetcb(), as otherwise group_leave() will be called + and group->tg_nmembers decremented or group being released. + group_leave() should be called only after group_join() is called, + not after group_bind(). From Jussi Kivilinna (2015-07-01). + * arch/arm/src/sama5/sam_ehci.c: Fix some bad conditional compilation + that left a function undefined if CONFIG_USBHOST_ASYNCH is not + selected (2015-07-01). + * arch/arm/src/common/up_vfork.c: Fix a Cortex-A compilation error + when system calls are enabled in modes other than CONFIG_BUILD_KERNEL + (2015-07-01) + * include/nuttx/net/netconfig.h: Fix some backward compilation that was + emitting #error in the wrong condition when SLIP was enabled (2015-07-01). + * drivers/net/slip.c: Fix a missed name change when many of network + interface names changed sometime back but were apparently never updated + for SLIP (2015-07-01). + * drivers/input/stmpe811_base.c: In stmpe811_instanciate() when + CONFIG_STMPE811_MULTIPLE is enabled, and the call to stmpe811_checkid() + fails, then the linked device list is not restored to its previous state. + From Sebastien Lorquet (2015-07-02). + * sched/sched/sched_waitpid.c: Implement WNOHANG for waitpid() only and + for the case of CONFIG_SCHED_HAVE_PARENT not selected.

From Alessandro Temil (2015-07-09). + * mm/umm_heap, include/nuttx/kmalloc.h, userspace.h, mm/mm.h, and all + configurations that support protected mode: Redesigned how the user + space heap is accessed from the kernel code in protected mode. It + used to call memory management functions in user space via function + pointers in the userspace interface. That is inefficient because the + first thing that those memory management functions do is to trap back + into the kernel to get the current PID. Worse, that operation can be + fatal is certain fragile situations such as when a task is exiting. + The solution is to remove all of the memory management function calls + from the interface. Instead, the interface exports the users pace + heap structure and then kernel size implementations of those memory + management functions will operate on the userspace heap structure. + This avoids the unnecessary system calls and, more importantly, + failures do to freeing memory when a test exits (2015-07-10). + * libc/netdb: Move netdb functions from lib/net to lib/netdb. Move + the DNS client logic from apps/netutils/dnscient to libc/netdb. + Add support to gethostbyname() so that it will attempt a DNS host + lookup before consulting the host table (if so enabled) (2015-07-10). + * arch/arm/src/samdl/chip/saml_usb.h: Several fixes to register + definitions and types. From Janne Rosberg (2015-07-10). + * include/nuttx/net/ and libc/netdb: Repartitioning of DNS client + logic in preparation for IPv6 support (2015-07-12): + - Rename include/nuttx/net/dnsclient.h to dns.h + - Move internal DNS prototypes from dns.h to libc/netdb/lib_dns.h + - Global standard DNS definitions from libc/netdb/dns_soccket.c to + dns.h + - Eliminate dns_gethostip(). This is now an internal part of + gethostbyname() + - Eliminate interface dns_whois(). Not needed in this new context. + * include/nuttx/net/ and libc/netdb: Modifications to DNS client logic + and to dns_get/setserver() interfaces to support DNS clients at IPv6 + addresses (still no support for resolution to IPv6 addresses) + (2015-07-12). + * include/nuttx/net/ and libc/netdb: Implement the low-level network DNS + packet protocol to request and receive IPv6 address mappings + (2015-07-12). + * libc/netdb: Add a default value for DNS server IP address. Make + sure that the IP address has been initialized before permitting DNS + queries (2015-07-13). + * libc/netdb: Add support for a DNS host name resolution cache. This + can save a lot of DNS name server lookups (but might also have the + negative consequence of using stale IP address mappings (2015-07-13). + * graphics/, libnx/, and include/nuttx/nx: Implement anti-aliasing in + order to clean the drawing of all edges (2015-07-14). + * drivers/lcd/ and include/nuttx/lcd: Modify the SSD1306 LCD driver to + support either the SPI or I2C interface.

From Sebastien Lorquet (2015-07-17). + * STM32 F7 Discovery: Basic NSH configuration is functional with a + serial console. I-/D-Caches and DTCM have been enabled. The delay + loop has been calibrated -- very fast (2015-07-19). + * drivers/sensor and include/nuttx/sensors: Add support to Bosch BMP180 + barometer. From Alan Carvalho de Assis (2015-07-20). + * configs/stm32f4discovery/: Add support to BMP180 driver on the + STM32F4Discovery.

From David Sidrane (2015-07-22). + * include/nuttx/sched.h, sched/, and fs/procfs: Increase the size of + the scheduling policy field from 1 to 2 bits to allow additional, + planned scheduling policies (2015-07-23). + * pthread_create: Fix an (unlikely) error in fallback value in the + event of a failure (which should never occur) (2015-07-23). + * include/, sched/, and libc/: Add support for sporadic scheduling + parameters in struct sched_param, posix_spawnattr_t, and pthread_attr_t. + Update all user interfaces to pass sporadic scheduling parameters. + (2015-07-23). + * sched/: Separate the round-robin logic into a separate file so that + it is symmetric with the sporadic stuff. Integrate the sporadic + scheduler into the time tick interrupt handling and into the tickless + operation (2015-07-24). + * arch/arm/src/moxart/: Add support for MoxaRT SoC found in the most + Moxa serial converters such as NP51x0, NP66xx, UC72xx. From Anton + D. Kachalov (2015-07-29). + * configs/moxa: Moxa NP51x0 series of 2-port advanced RS-232/422/485 + serial device servers. From Anton D.

It is a non-standard but more efficient version of sem_timedwait() + for use in higher performance device drivers (2015-08-01). + * drivers/net/slip.c: Fix another compilation error (2015-08-02). + * drivers/can.c include/nuttx/can.h, and fs/fs.h: Add CAN IOCTL command + definitions to manage CAN message filtering (2015-08-05) + * drivers/Kconfig and can.c: Add configuration to support DLC to byte + conversions needed for CAN FD mode (2015-08-05). + * arch/arm/src/samv7: Add an MCAN driver for the SAMV7 platform + (2015-08-06). + * drivers/sensors/lm92.c and include/nuttx/sensors/lm92.h: Add a driver + for the LM92 temperature sensor. Contributed by Paul Alexander Patience + (2015-08-06). + * drivers/sensors/as5048b.c and include/nuttx/sensors/as5048b.h: Add + support for an AS5048B rotary magnetic sensor.

From Paul Alexander Patience + (2015-08-12). + +7.12 2015-10-01 Gregory Nutt + + * fs/vfs/fs_poll.c: Use sem_tickwait() instead of sem_timedwait() + From Macs Neklyudov (2015-08-13). + * fs/vfs/fs_poll.c: If we fail to setup the poll for any file + descriptor, for any reason, set the POLLERR bit (2015-08-13). + * libc/stdlib: Add support for div() to the C library. From + OrbitalFox (2015-08-14). + * libc/stdlib: Might as well add ldiv() and lldiv() to since + these are equivalent to div() with long and long long types, + respectively, instead of int (2015-08-14). + * include/signal.h and files that include it: Add si_errno to + siginfo_t (2015-08-14). + * drivers/sensors/mx58xx.c and include/nuttx/sensors/ms58xx.h: + Generalize the MS5805 altimeter driver to support other family + members and rename to ms58xx. From Paul Alexander Patience + (2015-08-14). + * Network drivers. Fix bug in tun interface driver. From Max + Neklyudov (2015-08-17). + * STM32: Added definitions for STM32F303K6, STM32F303K8, STM32F303C6, + STM32F303C8, STM32F303RD, and STM32F303RE devices. From Paul + Alexander Patience (2015-08-17). + * include/nuttx/can.h and all CAN drivers: Add an error indication + bit to the CAN message report. This indication must then be cleared + in all existing drivers. More to come (2015-08-18). + * arch/arm/src/lpc17/lpc17_irq.c: Set NVIC vector address so that + code can execute with a bootloader or can execute from RAM. From + Pavel Pisa (2015-08-20). + * All ARMV7-M IRQ setup: Always set the NVIC vector table address + unconditionally. This is needed in cases where the code is running + with a bootload and when the code is running from RAM. It is also + needed by the logic of up_ramvec_initialize() which gets the vector + base address from the NVIC. Suggested by Pavel Pisa (2015-08-21). + * SAMV7 USBHS DCD: The device controller driver is (finally) functional + (2015-08-21). + * recvfrom(): Correct wait for new data when NET_UDP_READAHEAD is + enabled. Fix size accounting when recvfrom_udpreadahead() sets + state.rf_recvlen == -1. I have not checked if data are accumulated + to the right position in the buffer however. From Pavel Pisa + (2015-08-21). + * sched/wdog/wd_create.c: Correct a counting error in the number + of available watchdog timers. When the number of free timers is + low, the counter could be incremented below zero (2015-08-21). + * arch/arm/src/stm32: Add OTG support for STM32F44x. From David + Sidrane (2015-08-21). + * arch/arm/src/lpc17: Actually implement options to use external + SDRAM and or SRAM for the heap. From Pavel Pisa (2015-08-21). + * gethostbyname(): correct returned address format when DNS is used. + The hostent.h_addr_list should point to raw in_addr or in6_addr + as defined in the standard. Original implementation used that + for numeric addresses but for DNS lookup returned pointer to + whole sockaddr_in or sockaddr_in6. From Pavel Pisa (2015-08-21). + * tools/mksymtab: declare g_symtab array as const to occupy RO + section (Flash). From Pavel Pisa (2015-08-23). + * libc/libc.csv and syscalls/syscalls.csv: Define some symbol + export conditions, correct errno and add sleep and usleep. From + Pavel Pisa (2015-08-23). + * net/ and include/nuttx/net: Remove references to PPP as a + link layer protocol (2015-08-24). + * net/, drivers/net, and include/net: Add definitions to support + a local loopback device and link layer (2015-08-24). + * libc/netdb, net/loopback, include/nuttx/net: Add NetDB support + for the local loopback device (2015-08-24). + * drivers/net/loopback.c: Add basic prototype of a local loopback + device (2015-08-24). + * networking: Correct return value from psock_tcp_accept().

Originally + planned to use the SPI interface, but it is just now compatible + with the SAMV71 QSPI hardware (2015-08-25). + * drivers/rwbuffer.c: Fix some logic errors. From Dmitry Nikolaev + via Juha Niskanen (2015-08-26). + * net/socket and net/tcp: Fix a problem in when there are multiple + network devices. Polls were being sent to all TCP sockets before. + This is not good because it means that packets may sometimes be + sent out on the wrong device. That is inefficient because it + will cause retransmissions and bad performance. But, worse, when + one of the devices is not Ethernet, it will have a different MSS + and, as a result, incorrect data transfers can cause crashes. + The fix is to lock into a single device once the MSS is locked + locked down (2015-08-27). + * drivers/lcd and include/nuttx/lcd: Add SSD1351 OLED controller + support. Contributed by Paul Alexander Patience (2015-08-28). + * include/nuttx/mtd/mtd.h: Move MTD ioctl command definitions from + include/nuttx/fs/fs.h to include/nuttx/mtd.h.

From Bruno Herrera (2015-08-30). + * arch/arm/src/up_internal.h and several ARM Make.defs files: In the + original implementation, !defined(CONFIG_ARMV7M_CMNVECTOR) was a + sufficient test to determine if lazy floating point register saving + was being used. But recents changes added common lazy register as + well so now that test must be (!defined(CONFIG_ARMV7M_CMNVECTOR) || + defined(CONFIG_ARMV7M_LAZYFPU)) (2015-08-31). + * arch/arm/include/sama5 and src/sama5: Add basic chip description, + configuration support and interrupt definitions for the SAMA5D2 + (2015-08-31). + * LPC43xx: Fix NVIC_SYSH_PRIORITY_STEP define. From Ilya Averyanov + (2015-09-01). + * LPC43xx: Fix missing #define in eeprom. From Ilya Averyanov + (2015-09-01). + * libc/math/lib_asin.c: The function did not convert for some input + values. Asin did not convert for values which do not belong to the + domain of the function. But aside of that the function also did not + converge for some allowed values. I achieved a conversion of the + function by reducing the DBL_EPSION and by checking if the input + value is in the domain of the function. This is a fix for the + problem but the function should always terminate after a given + number of iterations. From Stefan Kolb (2015-09-01). + * arch/arm/src/lpc43xx/lpc43_spi.c: Fix SPI driver. From Ilya + Averyanov (2015-09-02). + * arch/arm/src/lpc43xx/lpc43_ethernet.c: Add Ethernet support. From + Ilya Averyanov (2015-09-02). + * net/tcp: The logic that binds a specific network device to + a connection was faulty for the case of multiple network + devices. On bind(), the local address should be used to associate + a device with the connection (if the local address is not INADDR_ANY); + On connect(), the remote address should be used (in case the local + address is INADDR_ANY). On accept(), it does not matter but the + remote address is the one guaranteed to be available (2015-09-02). + * configs/Board.mk and configs/*/src/Makefile: Simplify configs/ + Makefiles by combining common logic into a new Board.mk Makefile + fragment. From Paul Alexander Patience (2015-09-04). + * configs/sama5d2-xult: Add a very basic configuration for the SAMAD2 + Xplained Ultra board.

Noted by + Stefan Kolb (2015-09-14). + * All ARMV7-M: Force 8-byte stack alignment when calling from assembly + to C to interrupt handling (2015-09-15). + * drivers/power/battery_gauge.c and include/nuttx/power/battery_gauge.h: + battery.c/h renamed to batter_gauge.c/.h since it really only + implements a battery fuel gauge. From Alan Carvalho de Assis (2015-09-19). + * drivers/power/battery_charger.c and include/nuttx/power/batter_charger.h: + Add a new framework to support a batter charger interface.

From Paul + Alexander Patience (2015-09-29). + * arch/arm/src/armv7-m/up_schedulesigaction.c: Fix logic that determines + if there is a pending signal action before scheduling the next signal + action. Both the test and the scheduling action need to be atomic + (2015-09-30). + * sched/wqueue/kwork_queue.c and libc/wqueue/work_queue.c: Logic that + sets the queued indication and the logic that does the actual queuing + must be atomic (2015-09-20). + +7.13 2015-12-05 Gregory Nutt + + * libc/stdlib/lib_bsearch.c and include/stdlib.h: Add the bsearch() + function from NetBSD (2015-10-02). + * libc/stdlib/lib_qsort.c and include/stdlib.h: Make coding style + more conformant, take description from OpenGroup.org, rename formal + parameters to match names used on OpenGroup.org (2015-10-02). + * drivers/lcd/st7565.c: Extend to include support for the ERC12864-3. + From Pierre-noel Bouteville (2015-10-07). + * fs/tmpfs: Created a directory that will eventually hold a trivial + temporary RAM file file system (2015-10-0i8). + * tools/: Add crappy style checking tool nxstyle.c.

See the top-level TODO file for additional details + (2015-12-30). + * include/nuttx/compiler.h, include/nuttx/streams.h include/stdio.h + include/syslog.h libc/stdio/, and libc/syslog: introduce support for + Atmel toolchain in-flash strings. Atmel toolchain AVR compiler + provides a transparent in-flash object support using __flash and + __memx symbols. The former indicates to compiler that this is a flash- + based object. The later used with pointer indicates that the referenced + object may reside either in flash or in RAM. The compiler automatically + makes 32-bit pointer with flag indicating whether referenced object is + in flash or RAM and generates code to access either in run-time. Thus, + any function that accepts __memx object can transparently work with RAM + and flash objects. + For platforms with a Harvard architecture and a very small RAM like AVR + this allows to move all constant strings used in trace messages to flash + in the instruction address space, releasing resources for other things. + This change introduces IOBJ and IPTR type qualifiers. The 'I' indicates + that the object may lie in instruction space on a Harvard architecture + machine. For platforms that do not have __flash and __memx or similar + symbols IOBJ and IPTR are empty, making the types equivalent to, for + example, 'const char' and 'const char*'. For Atmel compiler these will + become 'const __flash char' and 'const __memx char*'. All printf() + functions and syslog() functions are changed so that the qualifier is + used with the format parameter.

It should not be a global function; + Now it is an I2C interface method (2016-02-02). + * I2C: Rename up_i2cinitialize and up_i2cuninitilize to follow the correct + naming convention. These are not common interfaces used by the OS; + these are MCU-specific interfaces used only be MCU-specific code. The + the correct naming is xyz_i2cbus_initialize and xzy_i2cbus_uninitialize + where xzy is the MCU mnemonic (2016-02-02). + * Networking drivers that support CONFIG_NET_NOINTS: Fix a race condition + that can cause the TX poll timer to stop running. From Manuel Stuhn + (2016-02-03). + * All Network drivers: Remove the hsec parameter from devif_timer(). + We can get better timing accuracy without it (2016-02-03). + * drivers/ioexpander/pca555.c: Add logic to make the PCA555 driver + thread safe (2016-02-03). + * sched/init/os_start.c and include/nuttx/init.h: Add a state variable + that provides the current level of OS initialization. This is needed by + some logic that may attempt to run early in the start-up sequence but + cannot run if a sufficient level of initialization has not yet occurred + (2016-02-05). + * libc/syslog/lib_syslog.c: If syslog timestamping is enabled, don't try to + get the time if the timer hardware has not yet been initialized + (2016-02-05). + * fs/procfs/fs_procfskmm.c: Add /proc/kmm entry that shows that state of + the kernel heap. Only useful in PROTECTED and KERNEL build modes where + there is a kernel heap (2016-02-06). + * sched/ and arch/: Replace explicit access to the OS internal data structure + g_readytorun() with the wrapper this_task() which hides the implementation + and will permit such things as more scalable representations of task queues + and SMP (2016-02-06). + * include/nuttx/net/arp.h, include/nuttx/net/ioctl.h, net/netdev/netdev_ioctl.c, + and ARP-related files: Add support for IOCTL commands to manage the + ARP table (2016-02-08). + * ARMv7-A, ARMv7-R, and ARMv7-A: Add test-and-set logic and definitions + needed to supports spinlocks (2016-02-09). + * include/nuttx/spinlock.h: Add basic definitions for spinlocks. Not yet + used by NuttX (2016-02-09). + * include/nuttx/arch.h, sched/sched/sched.h: Add some basic definitions + that may be needed for SMP support (2016-02-10). + * sched/init/os_start.c, sched/init/os_smpstart.c, and include/nuttx/arch.h: + Add some tentative SMP start-up logic (2016-02-10). + * arch/arm/sim/up_head.c and up_simsmp.c: Add multi-CPU support to the + simulation to support SMP investigation.. Currently crashes when CONFIG_SMP + is enabled as expected (2016-02-10). + * sched/sched.h and other files: Replace the bool 'prioritized' in the task + list table with a uint8_t bit set so that additional attributes of a task + list can be provided without adding more booleans (2016-10-11). + * Everywhere: Replace irqsave() with enter_critical_section(); replace + irqrestore() with leave_critical_section(). This is part of the onging + development of SMP support (2016-02-13). + * Conform to naming convention: Rename irqsave() to up_irq_save(); rename + irqrestore() to up_irq_restore(). These should no longer be used. If + your code still uses them, please switch to enter_critical_section() + and leave_critical_section() (2016-02-14). + * Also rename irqdisable() and irqenable() to up_irq_disable() and + up_irq_enable() (2016-02-14). + * sched/signal and include/nuttx/sched.h: Move the list of signal + actions from the TCB to the group structure. Signal handlers are not + per thread but, rather, per task group. I know, I preferred it the + other way too, but this is more compliant with POSIX (2016-02-18). + * fs/ procfs/fs_procfsproc.c: Add support for showing CPU if SMP is + enabled (2016-02-19). + * include/pthread.h, sched.h, sys/types.h and other files: Rename + cpuset_t to cpu_set_t which is the type used in some non-standard + Linux/GNU interfaces. Move definitions of cpu_set_t to include/sys/types.h. + Add prototypes for sched_setaffinity(), sched_getaffinity(), + pthread_attr_setaffinity_np(), pthread_attr_getaffinity_np(), + pthread_setaffinity_np(), and pthread_getaffinity_np(). No implementation + is yet in place (2016-02-19). + * sched/sched_cpuselect.c, include/nuttx/sched.h, and other files. Add + a CPU affinity set to the TCB if SMP is enabled and use this CPU set as + a mask for determining which CPUs the thread may run on (2016-02-19). + * libc/pthread, sched/pthread/pthread_start.c, and include/pthread.h: + Add an affinity field to the attrributes to permit controlling + which CPUs a pthread may run on. Implements pthread_att_setaffinity_np() + and pthread_attr_getaffinity_np() (2016-02-19). + * sched/pthread: Add pthread_setaffinity() and pthread_getaffinity() + (2016-02-19). + * sched/sched: Add sched_setaffinity() and sched_getaffinity() (2016-02-19). + * drivers/leds/rgbled.c: Add a driver to manage a RGB LED via PWM. From + Alan Carvalho de Assis (2016-02-22). + * arch/arm/src/stm32f4discovery: Add PWM support for the onboard RGB LED + From Alan Carvalho de Assis (2016-02-22). + * arch/arm/src/samv7: HSMCI driver can now be configured to handle unaligned + data buffers (2016-02-22). + * fs/fat: Add an option to force all transfers to be performed indirectly + using the FAT file system's internal sector buffers (2016-02-22). + * drivers/wireless/ieee802154: New directory. Nothing there yet (2016-02-25). + * wireless/: New top level directory. Nothing there yet (2015-02-26). + * wireless/ieee802154: Add an new directory to the build. Nothing there + yet (2016-02-26). + * include/nuttx/wireless/ieee802154: Add directory (and dummy header file) + (2016-02-16). + * arch/arm/include and src: Rename the imx directories to imx1 to make room + in the namespace for other members of the i.MX family (2016-02-27). + * arch/arm/include/imx6 and src/imx6: Evolving support for the NXP/Freescale + i.MX6Q (2016-02-28). + * configs/sabre-6quad: Placeholder that will eventually become board support + for the NXP/Freescale Sabre 6Quad board (2016-02-28). + * arch/arm/src/stm32: Support for STM32F46xx from Paul Alexander Patience + * sched/semaphore/sem_reset.c and include/nuttx/semaphore.h: Add an internal, + non-standard interface to reset a semaphore count. This is sometimes + needed by drivers in order to recover from error conditions (2016-03-05) + * AT24xx driver: Correct missing address calculation logic. From Frank + Benkert (2016-03-08). + * arch/ renaming: current_regs renamed to g_current_regs in all + architectures. For ARM which is slowly developing SMP capability, + g_current_regs is now an array of dimension 1 in most case but of higher + dimension of the architecuture supports multiple CPUs (2016-03-09). + * MTD: Increase block size in mtd_geometry_s to 32-bits (2016-03-09). + * include/nuttx/clock.h: Missing parenteses in MSEC2TICK macro can + cause wrong calculations. From Stefan Kolb (2016-03-09). + * Build system: Added a 'make olddefconfig' target that will refresh + a .config file without interaction. tools/refesh.sh now has a --silent + option so that it can be used in batch modes without human input + (2016-03-09). + * tools/testbuild.sh: .config files were not being updated because (a) + kconfig-conf was being called in the wrong directory and (b) apps/Kconfig + had not yet been created. Now uses 'make olddefconfig' (2016-03-09). + * arch/arm/src/stm32l4 and include/stm32l4: Add support for the STM32L4 + family. From Sebastien Lorquet (2016-03-10). + * configs/nucleo-l476: Add support for the Nucleo-L476 board. From + Sebastien Lorquet (2016-03-10). + * sched/tls and include/nuttx/tls.h: Basic definitions needed to support + thread local storage (TLS). Not used anywhere yet (and may not be used + in the near future either) (2016-03-10). + * sched/sched_note.c and include/nuttx/sched_note.c: Add a configuration + option to buffer RTOS instrumentation data in an in-memory buffer + (2016-03-17). + * drivers/syslog/note_driver.c: Add a character driver that will allow + an application to read buffered scheduler instrumentation data (2016-03-17). + * arch/arm/src/samv7/sam_usbdevhs.c: The USB driver has had some issue that + would occasionally cause loss of packets. Back last December, a fix was + put in for this but the fix apparently worsens the problem; now causing + hangs. The basic problem is that the number of busy banks (NBUSYBKS) + status is not real time but is delayed. This was fixed; now when the DMA + completes and NBUSYBKS > 0, the NBUSYBK is interrupt is enabled and the + operations are deferred until NBUSYBKS is truly zero (2016-03-17). + * net/tcp/tcp_timer.c: Fix some logic when there are multiple network + interfaces. In this case, TCP timeout events can really only being + processed when the poll from the correct device is received (2016-03-20). + * sched/wqueue/kwork_signal.c: Fix logic to find an IDLE worker thread; + the test for busy was backward. From Linfei Chen (2016-03-22). + * include/sys/boardctl.h, configs/boardctl.c, and many configurations: Add + boardctl() support that will permit applications to control USB devices + (2016-03-25). + * configs/stm32l476vg-disco: Add support for the STM32L476VG Discovery + board. From Dave (2016-03-25). + +7.16 2016-06-01 Gregory Nutt + + * PM: Add activity domain to all PM interfaces and driver callbacks. If + CONFIG_PM_NDOMAINS == 1, then the legacy behavior is preserved. If + CONFIG_PM_NDOMAINS > 1, then multiple PM domains are supported. This + will allow separate control for certain power management groups. For + example, a network can be shut down without affect an ongoing UI (and + vice versa) (2016-03-27). + * apps/configs/vsn: Removed the VSN configuration from the main NuttX + repository. The VSN can still be found in the Obsoleted repository + (along with a full explanation in the README file there) (2016-03-29). + * arch/arm/src/armv7-m and stm32: Add support for the IAR toolchain for + the limited case of the ARMv7-M architecture and the STM32 chip. From + Aleksandr Vyhovanec (2016-04-02). + * arch/arm/src/stm32/stm32f40xxx_rtc.c: Add a custom RTC driver. From + Neil Hancock (2016-04-02). + * include/nuttx/timer/rtc.h and drivers/timers/rtc.c: Simplify the RTC + interface. The old interface was way to complex and was not fully + implemented anywhere (2016-04-02). + * Moved NuttX repository to https://bitbucket.org/nuttx/nuttx (2016-04-06). + * arch/arm/src/armv7-m/iar: Convert more assembly language files for + use with the IAR toolchain. From Kha Vo (2016-04-08) + * Fix miscellaneous build issues for the IAR compiler. From Kha Vo + (2016-04-08). + * tools/ide_exporter.py: IDE exported Python script for use with the + IAR toolchain. From Kha Vo (2016-04-08). + * STM3220G-EVAL: Add support for both the IAR and uVision GCC IDEs + From Kha Vo (2016-04-08). + * STM32F429I Discovery: Add support for the uVision GCC IDE. From + Kha Vo (2016-04-08). + * libc/signal and include/signal.h: Rename sigset() to signal(). + sigset() is the System V function; signal() is the obsoleted POSIX + name. These seem to be equivalent. Neither are relevant in modern + POSIX programming but the name signal() probably has the better + credentials. sigset() is now relegated to a #define in signal.h that + makes it equivalent to signal() (2016-04-10). + * configs/nucleus2g: Removed the Nucleus2G configuration. There has + not been any activity with the commercial board in a few years and it + no longer appears to be available from the 2g-eng.com website. + Since the board is commercial and no longer publicly available, it + no longer qualifies for inclusion in the open source repositories. + The code as of this data is still available in the Obsoleted + repository at configs/nucleus2g (2016-04-12). + * arch/arm/src/stm32l4: Fix the STM32L4 SPI driver. That SPI driver is + quite different. They now handle frames of arbitrary size between 4 + and 16 bits. It was broken before a new bit has to be set (RX fifo + threshold) to handle <= 8-bit transactions. If not set, the default is + 16-bit packed >=8-bit frames and the RXNE bit is never set (it is set + when 16-bits are received). weird things as always. + This also add 8-bit access routines to the data register, because a + 16-bit access to the data register when the frame size is below 9 bits + is interpreted as a packed dual frame exchange. Sebastien Lorquet + (2016-04-13). + * net/sockets/listen.c and accept.c and include/nuttx/net: Separate + out psock_listen() and psock_accept() for internal OS usage + (2016-04-14). + * fs/inode/, fs/vfs/, and sched/task/: File and socket descriptors are + no longer allocated for kernel threads. They must use SYSLOG for + output and the low-level psock interfaces for network I/O. This + saves a little memory which might be important for small footprint + configurations (2015-04-14). + * Framebuffer driver: Add a display number to each interface in order + to support multiple display devices (2015-04-14). + * drivers/wireless/nrf24l01.c: Fix backward calculation of relative + frequency. Noted by Henry Zhang (2015-04-15). + * drivers/sensors/h1750fvi.c: Add a character driver for Rohm Ambient + Light Sensor BH1750FVI. From Alan Carvalho de Assis (2016-04-15). + * configs/stm32f4discovery: Integrate BH1750FVI driver in the + STM32F4Discovery board. From Alan Carvalho de Assis (2016-04-15). + * drivers/mtd: Add MTD support for Micron N25Qxxx family of QSPI flash. + From Dave dev@ziggurat29.com (2016-04-17). + * arch/arm/src/stm32l: Add a QSPI driver. From Dave dev@ziggurat29.com + (2016-04-18). + * configs/stm32l476vb-disco: Add support for QSPI based N25Qxxx flash. + From Dave dev@ziggurat29.com (2016-04-18). + * graphics/vnc: Add support for a VNC server. This logic is code + complete, but untested and so not ready for prime time (2016-04-18). + * configs/samv71-xult/vnc: Add a configuration that will be used to + verify VNC (also untested) (2016-04-18). + * drivers/ioexpander: Fix an error in the PCA9555 driver: Under certain + error conditions, interrupts were not being re-enabled. Sebastien + Lorquet (2016-04-20). + * arch/arm/src/stm32 and configs/stm32f429i-disco: Correct some bad + commits that broke the LTDC display example. From Marco Krahl + (2016-04-22). + * configs/samv71-xult/vncwwm: Add a more complex NxWM configuration + to support further VNC testing (particularly of VNC keyboard and + mouse inputs). Initial configuration is not functional (2016-04-23). + * arch/arm/src/stm32l4: Add support for QSPI DMA. From Dave + dev@ziggurat29.com (2016-04-24). + * configs/stm32l476vg-disco: Update stm32l4 disco board to reflect QSPI + DMA support. From Dave dev@ziggurat29.com (2016-04-24). + * arch/arm/src/stm32l4: Add configuration options to allow SRAM2 to be + used for heap, or not at all, and to zero-initialize it on OS start, + or not at all. From Dave dev@ziggurat29.com (2016-04-24). + * drivers/mtd/smart.c: Return code of smart_scan not checked, can + cause success result in failure case, leading to 'dev' pointer being + invalid. From Dave dev@ziggurat29.com (2016-04-27). + * arch/arm/src/stm32l4: Add support for QSPI memory mapped mode. From + Dave dev@ziggurat29.com (2016-04-27). + * configs/stm32l476vg-disco: Add board ioctls for allowing user + application to cause QSPI memory mapped mode to be engaged and + disengaged. Also partitioned QSPI flash for file system and other + (eventually xip). From Dave dev@ziggurat29.com (2016-04-27). + * fs/mount: Fix a backward debug assertion. Noted by David Sidrane + (2016-04-29). + * arch/arm/src/stm32l4: Add support for HSE and MSI clocks, and auto + trim of MSI to LSE (needed for USB). From Dave dev@ziggurat29.com + (2016-04-29). + * arch/arm/src/stm32l4: Add support for unique id function to arch; + modified board to support unique id boardctl. From Dave + dev@ziggurat29.com (2016-05-03). + * Makefile.unix and tools/mkexport.sh: Pass top-level make to the + script to allow -j greater than 1. From David Sidrane (2016-05-04). + * arch/arm/src/stm32, stm32f7, stm32l4: Fix typo in variable name in + serial BREAK logic. Review other serial implementations for similar + naming problems. (2016-05-05). + * arch/arm/src/samv7: Fix typo in MATRIX register definitions. From + Stefan Kolb (2016-05-06). + * arch/arm/src/stm32l4: Problem with resetting backup domain clears + clocking options set up before in *rcc.c use INITS flag to avoid magic + reg value to detect power up reset state of RTC correct a problem + clearing interrupt flags (they weren't) which prevented an alarm from + ever being used more than once per reset cycle. From Dave + dev@ziggurat29.com (2016-05-07). + * arch/arm/src/tiva: Fix a bug of GPIO falling-edge interrupt for tiva. + From Young (2016-05-07). + * drivrs/mtd: Add a driver for SST26F spi/qspi flash devices (SPI mode + only). From Sebastien Lorquet (2016-05-10). + * Several Makefiles: Add .PHONY definitions to prevent 'clean up to date' + message weirdness when 'make clean' is done with no .config or Make.defs + file (2016-05-10). + * include/nuttx/can.h and drivers/can.c: Improve CAN error reporting. + From Frank Benkert (2016-05-11). + * fs/Kconfig: Allow CONFIG_FS_WRITABLE to be manually selectable + (2016-05-11). + * Various file: Search for places where a stray semicolon following an + if condition cause the if body to be executed unconditionally. Fixes + in all SAM DMA logic, unionfs, OS signalling logic, + * configs/nucleo-144: Basic port for the Nucleo-144 board with the + STM32F746ZG MCU.

This is a very minimal port at present and probably still + has some as-of-yet-undiscovered issues (2016-05-17). + * arch/*/Makefile: Add definitions that can be overrided to use GCC + instead of LD in the final link. From Paul Alexander Patience + (2016-05-18) . + * arch/arm/src/stm32, stm32l4, and stm32f7 serial: Add support for + compliant BSD-style breaks. From David Sidrane (2016-05-18). + * enter/leave_critical_section() may attempt to access task lists before + they have been initialized in the SMP configuration (2016-05-18). + * configs/stm32f103-minimum: Add support for this minimual STM32F103CBT6 + "blue" board. From Alan Carvalho de Assis (2016-05-18). + * arch/arm/src/sam* Watchdogs: Rename up_wdginitialize() to something + more appropriate for an internal, MCU-specific function (2016-05-18). + * configs/*/src/*_watchdog.c: Remove all implementations of + up_wdginitialize() which was only used by apps/examples/watchdog. + That internal OS function is no longer called from application code. + If you want to use the watchdog example, you will need to configure + the watchdog driver by calling the appropriate, MCU-specific driver + configuration function from your board initialization logic + (2016-05-18). + * arch/srm/src/stm32l4: Add CAN support for STM32L4. From Sebastien + Lorquet (2016-05-19). + * arch/arm/src/samv7: Adds a JTAG config and ERASE config to Kconfig to + set the CCFG_SYSIO SYSIO Pins. From David Sidrane (2016-05-19). + * arch/sim/src: Enhance networking support for the simulation under Linux. + Includes updated support for Linux TUN/TAP, and the addition of support + for Linux bridge devices. From Steve (2016-05-20). + * configs/stm32f411e-disco: Add basic configuration for stm32f411e-disco + board with STM32F411VE chip. From Konstantin Berezenko (2016-05-20). + * i.MX6 Sabre-6Quad: Basic SMP NSH configuration is now working. But + this is probably only because the SMP NSH case does not stress the + logic. There are know outstanding SMP issues as noted in the + Sabre-6Quad README.txt file (2016-05-22). + * configs/sabre-6quad: Add an SMP configuration; Enable procfs in all + configurations (2016-05-22). + * include/nuttx/crypto/aes.h: Modifications to the crypto API needed + for LPC43xx. From Alexander Vasiljev (2016-05-23). + * arch/arm/src/lpc43xx: Add AES support. From Alexander Vasiljev + (2016-05-24). + * configs/*/src/tiva_timer.c: Tiva boards: Fix a naming collision, + rename board-specific function from tiva_timer_initialize() to + tiva_timer_configure() to remove conflict (2016-05-23). + * arch/arm/src/sam*: Ensure that the TWIHS (i2c) hw get's its clock + set when the sequence of sam_i2cbus_initialize(), + sam_i2cbus_uninitialize(), then sam_i2cbus_initialize() or twi_reset() + is called. I found this a while back in the stm32 family, so there + may be more arch-es with this sort of bug. I suppose any driver that + has the notion of "do not set the freq if it is already set" could be + suspect. From David Sidrane (2016-05-23). + * arch/arm/src/samv7: Add the up_systemreset interface to the samv7 + arch. The approach is slightly different in that: 1) It enables + ARCH_HAVE_RESET and allows the user to set if, and for how long, to + drive External nRST signal. It also does not contain a default + board_reset, as that really should be done in the config's src if + CONFIG_BOARDCTL_RESET is defined. From David Sidrane (2016-05-23). + * arch/arm/include/lpc43xx and src/lpc43xx: Adds definitions for the + LPC4337jet100 chip. From Alexander Vasiljev (2016-05-24). + * Many files: board_app_initialize() now accepts an argument that may + be used to support initialization in different configurations + (2016-05-24). + * arch/arm/src/samv7: Remove disabling of whole USB on suspend of USBHS. + This fix removes the disabling of the whole USB peripheral on suspend + interrupt. Its enough to freeze the clock instead. When disabling the + whole peripheral, the next wakeup-interrupt comes up with an disabled + clocking. The unfreeze clock has no effect, because the master clock + is disabled. This makes all registers, including the IDR unwriteable + and the IRQ falls in an endless loop blocking the whole system. + Furthermore the disabling of the peripheral clock prevents hotplugging + or reconnecting the USB. From Frank Benkert (2015-05-25). + * drivers/lcd: Add support for PCF8574 LCD Backpack driver. This driver + supports an interface board that is based on the PCF8574 io expander + and supports the HD44780-based (or compatible) LCD modules. There + are a myriad of different vendors of such, but they are principally + the same, save wiring and minor features like jumpers for I2C + addresses. This driver supports known and unknown variants. From + Dave (ziggurat29, 2013-6-26). + * arch/arm/stm32: Add support for a custom 1-wire driver. The serial + driver already supports a 1-wire interface, but this driver uses the + same serial logic to implement a lower half driver much like the I2C + lower half driver. From Aleksandr Vyhovanec (2015-05-25). + * fs/: Add logic to detach a file structure from a file descriptor. + This is for use only within the OS. It permits an open file or driver + to be used across multiple threads (2016-05-26). + * arch/arm/src/stm32l4: Get I2C working for STM32L4. From Dave + (ziggurat29) (2016-05-25). + * fs/ and include/nuttx/fs: Add logic to detach a file structure from a + file descriptor. This is for use only within the OS. It permits an + open file or driver to be used across multiple threads. (2016-05-26). + * drivers/analog/adc.c, include/nuttx/analog/adc.h, and all ADC lower + half drivers: No longer uses global adc_receive() call. Added a new + bind() method to the ADC interface. Now the ADC upper half driver + will register its receipt-of-data callback. This change allows the + ADC lower half driver to be used with a differ ADC upper half + (2016-05-26). + * drivers/analog/ads1255.c: Must not do SPI access from interrupt + handler. Use the worker thread instead. Must also lock the SPI bus + before using it. (2015-05-26). + * drivers/: Several SPI-based drivers modified. All drivers that use + SPI must call SPI_LOCK and SPI_UNLOCK. This is not optional + (2016-05-26). + * drivers/sensors: Fix a bug in crc computation for ms583730. + Implement POSIX read (2016-05-27). + * arch/arm/src/samv7: This is a fix to a problem in the handling of the + oneshot timer. Due to a wrong assumption concerning the behavior + directly after the start of the timer/counter the function + sam_oneshot_cancel(…) calculates the wrong remaining time. The code + assumes that the counter register is zero directly after the start of + the timer, but this is not true. To start the time/counter a software + trigger is invoked, this trigger starts the timer/count and sets the + counter register to zero, but the reset of the counter register is not + performed instantly. According to the datasheet: "The counter can be + reset by a trigger. In this case, the counter value passes to zero on + the next valid edge of the selected clock." Thus the counter is set to + zero between 0 and USEC_PER_TICK microseconds after the clock was + started. + In my fix I use the freerun count value to determine if at least one + tick passed since the start of the timer and thus if the value of the + oneshot counter is correct. I also tried to use the function + up_timer_gettime(…) to achieve this but, at least if compiled with no + optimization the problem vanishes without using the value of the + function, the function call takes too long. + Another problem treated in the fix is that if the oneshot timer/counter + is canceled, we only know the remaining time with a precision of + USEC_PER_TICK microseconds. This means the calculated remaining time + is between 0 and USEC_PER_TICK microseconds too long. To fix this I + subtract one tick if the calculated remaining time is greater than one + tick and otherwise set the remaining time to zero. By doing so the + measured times are much more precise as without it.

In short, this option switches + the processor from "fixed peripheral selection" (single device) to + "variable peripheral selection" (multiple devices on the bus). + - Add a new Function to the interface to control the timing and delays + of the chip according the ChipSelect lines. This function can + control the delay between the assertion of the ChipSelect and the + first bit, between the last bit and the de-assertion of the + ChipSelect and between two ChipSelects. This is needed to tune the + transfer according the specification of the connected devices. + - Add three "hw-features" for the SAMV7, which controls the behavior + of the ChipSelect: + - force CS inactive after transfer: this forces a (short) + de-assertion of the CS after a transfer, even if more data is + available in time + - force CS active after transfer: this forces the CS to stay active + after a transfer, even if the chip runs out of data. + Btw.: this is a prerequisit to make the LASTXFER bit working at all. + - escape LASTXFER: this suppresses the LASTXFER bit at the end of the + next transfer.

But before + its retransmission starts, NuttX is correctly issuing next TCP + packets, with sequence numbers increasing properly. When the + retransmission of previously lost packet finally succeeds, tcp_input + receives the accumulated ACK value, which acknowledges also the + packets sent in the meantime (i.e. between unsuccessful sending of + lost packet and its proper retransmission). However, variable unackseq + is still set to conn->isn + conn->sent, which is truth only if no + further packets transmission occurred in the meantime. Because of + incorrect (in such specific case) unackseq value, few lines further + condition if (ackseq <= unackseq)is not met, and, as a result, we + are going to reset label.

From Paul Alexander Patience (2016-06-28). + * Build system: This change fixes a build problem that only occurs when + reconfiguring from Linux to Windows or vice-versa. It is a problem + that was present but not usually experienced until two things happened: + (1) The pre_config target was added to run before the menconfig + operation and (2) the context target was added before the pre_config + target in order to set up the correct symbolic links (in the apps/platform + directory) needed by the pre_config target. + But then now if you start with a Linux system and run 'make menuconfig' + to switch to Linux, the context target will execute first and set up + POSIX style symbolic links before doing the menuconfig. Then after the + menuconfig, the make will fail on Windows if you are using a Windows + native toolchain because that native toolchain cannot follow the Cygwin- + style symbolic links. + The fix here is to also execute the clean_context AFTER executing + menuconfig. A lot more happens now: It used to be that doing 'make + menuconfig' only did the menuconfig operation. Now it does context, + pre_config, menuconfig, clean_context.

Per comments from David Sidrane, file_ioctl() should not + return succeed if the ioctl method is not supported. It probably + should return ENOTTY in that case (2016-07-09). + * libm: This change should significantly improve the performance of + single precision floating point math library functions. The vast + majority of changes have to do with preventing the compiler from + needlessly promoting floats to doubles, performing the calculation + with doubles, only to demote the result to float. These changes only + affect the math lib functions that return float. From David Alessio + (2016-07-11). + * STM32F4 Discovery: Add FPU support for ostest for the STM32F4Discovery + platform. From David Alessio (2016-07-11). + * Build system: Remove the includes/apps link to apps/include. It is + no longer used.

From Heath + Petersen (2016-07-12). + * UART 16550: Handle when CONFIG_SERIAL_UART_ARCH_IOCTL is not enabled. + From Heath Petersen (2016-07-12). + * Kinetis Ethernet: Add support for the KSZ8081 PHY (2016-07-12). + * SST26 Driver: Before accessing the sst26 flash, the "Global Unlock" + command must me executed, which I do in the sst26 driver. BUT re- + reading the datasheet, the WREN instruction is required to enable the + execution of this command. This was not done. I have no idea how the + driver currently works except by chance. The writes should never + happen at all, the flash is half-enabled! From Sebastien Lorquet + (2016-07-12). + * Freedom K64F: Add a networking NSH configuration. (2016-07-12). + * N25Qxx Driver: Alter the notion of 'blocksize' to be equivalent to + 'flash write page size' in order to align with assumptions in the + smartfs driver (at least, maybe other things do as well). Correct a + bug that was previously masked by having blocksize=eraseblocksize + which would cause buffer overflows and delicious hardfaults. Trivial + spelling changes in comments, etc. From ziggurat29 (2016-07-12). + * STM32L476 Discovery: Update stm32l476 disco to include init code for + smartfs and nxffs for cases where those fs are included in build. + From ziggurat29 (2016-07-12). + * Kinetis Ethernet and Freedom-K64F: Freedcom-K64F PHY address was + wrong. Modified Ethernet driver to try all PHY addresses and then + only fail if the driver cannot find a usable PHY address. MDIO pin + must have an internal pull-up on the Freedom-K64F (2016-07-12). + * Kinetis Ethernet: Add support for CONFIG_NET_NOINTS (2016-07-12). + * SmartFS: Fix a 32-byte memory leak. From Ken Pettit (2016-07-12). + * Freedom-K64F: SDHC is now enabled in the nsh configuration (but does + not work)Add hooks for automounter; Change NSH configuration to use + Windows (2016-07-13). + * SAMV7 USBHS Device: This change solves a problem which causes data + loss while sending data via USB. This problem is caused by an incorrect + handling of the endpoint state in the USB driver sam_usbdevhs. This + leads under some circumstances to situations in which an DMA transfer + is setup while a previous DMA transfer is currently active. Amongst + other things I introduced the new endpoint state USBHS_EPSTATE_SENDING_DMA + for the fix. To reproduce the problem, I used a program which send as + many data as possible via a CDC/ACM device and verified the received + data on the PC. From Stefan Kolb (2016-07-13). + * STM32: Fix bug in oneshot timer. From Max Neklyudov (2016-07-13). + * STM32L4: Port foward bugfix from stm32 of oneshot timer. From + ziggurat29 (2016-07-13). + * STM32 and EFM32: I'm using syslog through ITM. In this case + syslog_channel function is call before RAM initialization in + stm32_clockconfig. But syslog channel uses a global variable that is + reset to default by the RAM initialization. From Pierre-noel + Bouteville (2016-07-14). + * LPC43xx SPIFI: If CONFIG_SPIFI_SECTOR512 undefined, lpc43_bwrite + doesn't do actual write (probably copy/paste errors). Still not sure + about current state of lpc43_spifi implementation, but for me NXFFS + works with this patch. From Vytautas Lukenskas (2016-07-14). + * SMART MTD layer: Fixes freesector logic error when sectorsPerBlk=256, + adds DEBUGASSERT for invalid geometry and additional memory debug + logic. Also fixes the dangling pointer on error bug. From Ken + Pettit (2016-07-14). + * arch/arm/src/lpc43xx: Extend LPC43xx EMC code to support SDRAM on a + dynamic memory interface. From Vytautas Lukenskas (2016-07-19). + * arch/sim/src: Add the simulated QSPI (N25Q) flash to the simulation + and modify sim up_spiflash.c to enable it to run with different MTD + drivers based on config options (currently m25p, sst26 and w25). + From Ken Pettit (2016-07-19). + * drivers/pipe: Add support to allocating different sizes for pipe and + fifo buffers. Adds mkfifo2() and pipe2() which are just like mkfifo() + and pipe(), but allow control of the size of the underlying, in-memory + circular buffer . Move pipe() and mkpipe() to nuttx/libc, they are no + longer core OS interfaces. Capability currenty used only by PTY logic + to support, configurable, smaller buffers for PTYs (2016-07-19). + * include/nuttx/drivers: Move driver-related files from include/nuttx + to include/nuttx/drivers. Move driver related prototypes out of + include/nuttx/fs/fs.h and into new include/drivers/drivers.h + (2016-07-20). + * include /nuttx/lib: Move library-related files from include/nuttx to + include/nuttx/lib (2016-07-21). + * drivers/serial/serial.c: Fix a race condition noted by Stefan Kolb. + Between the test if the TX buffer is full and entering a critical + section, bytes may be removed from the TX buffer making the wait + unnecessary. The unnecessary wait is an inefficiency, but not really + a problem. But with USB CDC/ACM it can be a problem because the + entire TX buffer may be emptied when we lose the race. If that + happens that uart_putxmitchar() can hang waiting for data to be + removed from an empty TX buffer (2016-07-22). + * arch/arm/src/stm32 and stm32l4: STM32 F4/L4 RTC ALARM: were enabling + interrupts too early in the power-up sequence, BEFORE the interrupt + system was being initialized (2016-07-23). + * drivers/ioexpander: GPIO driver: Add support for receiving signals + from interrupt pins (2016-07-23). + * drivers/usbdev: USBMSC: Add locks when removing request from queue. + From Wolfgang Reissnegger (2016-07-23). + * drivers/usbdev: USBMSC: Fix reversed logic on waiting for SCSI thread + start. The scsi thread was waiting for the wrong condition. However, + this was masked by the fact that the code creating the scsi thread was + also holding usbmsc_scsi_lock(priv) while initializing data, hence + this lock synchronized the scsi thread start with init completion. + From Wolfgang Reissnegger (2016-07-23). + * arch/arm/src/sam34: SAM3/4 UDP: Fix handling of endpoint RX FIFO + banks. This fixes a race condition where the HW fills a FIFO bank + while the SW is busy, resulting in out of sequence USB packets + (2016-07-23). + * Freedom-K64F: Add PWM support. From Jordan MacIntyre (2016-07-25). + +7.18 2016-10-08 Gregory Nutt + + * drivers/serial/pty.c, serial.c, usbdev/cdcacm.c, include/nuttx/fs/ioctl.h: + Fix FIONWRITE and add FIONSPACE. All implementations of FIONWRITE + were wrong. FIONWRITE should return the number of bytes waiting in + the outgoing send queue, not the free space. Rather, FIONSPACE should + return the free space in the send queue (2016-07-25). + * lib_dumpbuffer: Now prints a large on-stack buffer first to avoid + problems when the syslog output is prefixed with time. From Pierre- + noel Bouteville (2016-07-27). + * sched/clock and sched/sched: Add standard adjtime() interface and + basic timekeeping support. Normally used with an NTP client to keep + system time in synchronizationi. From Max Neklyudov (Merged on + 20160-07-28). + * arch/arm/src/stm32: Add timekeeping support for the STM32 tickless + mode. From Max Neklyudov (Merged on 20160-07-28). + * Top-Level Makefiles. Fix a chicken-and-egg problem. In the menuconfig + target, the context dependency was executed before kconfig-mconf. + That was necessary because the link at apps/platform/board needed to + be set up before creating the apps/Kconfig file. Otherwise, the + platform Kconfig files would not be included. But this introduces + the chicken-and-egg problem in some configurations. + In particular: (1) An NX graphics configuration is used that requires + auto-generation of source files using cpp, (2) the configuration is + set for Linux, but (3) we are running under Cygwin with (4) a Windows + native toolchain. In this case, POSIX-style symbolic links are set + up but the Windows native toolchain cannot follow them. + The reason we are running 'make menuconfig' is to change from Linux + to Cygwin, but the target fails. During the context phase, NX runs + CPP to generate source files but that fails because the Windows native + toolchain cannot follow the links. Checkmate. + This was fixed by changing all of the make menuconfig (and related) + targets. They no longer depend on context being run. Instead, they + depend only on the dirlinks target. The dirlinks target only sets + up the directory links but does not try to run all of the context + setup; the compiler is never invoked; no code is autogeneraed; and + things work (2016-07-28). + * tools/refresh.sh: Recent complexities added to apps/ means that + configuration needs correct Make.defs file in place in order to + configure properly (2016-07-28). + * tools/kconfig2html.c: Update to handle absolute paths when sourcing + Kconfig files (2016-07-29). + * libc/math: This fixes the following libc/math issues: (1) asin[f l]() + use Newton’s method to converge on a solution. But Newton’s method + converges very slowly (> 500,000 iterations) for values of x close + to 1.0; and, in the case of asinl(), sometimes fails to converge + (loops forever). The attached patch uses an trig identity for + values of x > sqrt(2). The resultant functions converge in no more + than 5 iterations, 6 for asinl(). (2) The NuttX erf[f l]() functions + are based on Chebyshev fitting to a good guess. The problem there’s a + bug in the implementation that causes the functions to blow up with x + near -3.0. This patch fixes that problem. It should be noted that + this method returns the error function erf(x) with fractional error + less than 1.2E-07 and that’s fine for the float version erff(), but + the same method is used for double and long double version which + will yield only slightly better precision. This patch doesn't address + the issue of lower precision for erf() and erfl(). (3) a faster + version of copysignf() for floats is included. From David S. Alessio + (2016-07-30). + * I/O Expander: Remove hard-coded PCA9555 fields from ioexpander.h + definitons. Add support for an attach() method that may be used when + any subset of pin interrupts occur (2016-07-31). + * PCA9555 Driver: Replace the signalling logic with a simple callback + using the new definitons of ioexpander.h. This repartitioning of + functionality is necessary because (1) the I/O expander driver is the + lower-lower part of any driver that uses GPIOs (include the GPIO + driver itself) and should not be interacting directly with the much + higher level application layer. And (2) in order to be compatible + with the GPIO driver (and any arbitrary upper half driver), the + PCA9555 should not directly signal, but should call back into the + upper half. The upper half driver that interacts directly with the + application is the appropriate place to be generating signal + (2016-07-31). + * drivers/ioexpander/skeleton.c: Add a skeleton I/O Expander driver + (based on the PCA9555 driver) (2016-07-31). + * I/O Expander Interface: Encode and extend I/O expander options to + include interrupt configuration (2016-07-31). + * drivers/ioexpander: Add an (untested) TCA64XX I/O Expander driver + leveraged from Project Ara (2016-07-31). + * I/O Expander Interface: Add argument to interrupt callback. Add a + method to detach the interrupt (2016-08-01). + * drivers/ioexpander: Add a GPIO lower-half driver that can be used to + register a GPIO character driver for accessing pins on an I/O expander + (2016-08-01). + * drivers/ioexpander: Add PCF8574 I/O Expander driver. Some cleanup + also of other expander drivers (2016-08-01). + * drivers/ioexpander: GPIO driver: Add IOCTLs to get the pin type and + to unregister a signal handler (2016-08-01). + * configs/sim: Add simulator-based test support for apps/examples/gpio + 2016-08-01). + * drivers/sensors: Add KXTJ9 Accelerometer driver from the Motorola + Moto Z MDK (2016-08-02). + * arch/arm/sim: Add a simulated I/O Expander driver (2016-08-03). + * configs/sim: Add logic to set the simulated I/O expander for testing + with apps/examples/gpio (2016-08-03). + * fs/fat: FAT performance improvement. In large files, seeking to a + position from the beginning of the file can be very time consuming. + ftell does lssek(fd, 0, SET_CURR). In that case, that is wasted time + since we are going to seek to the same position. This fix short- + circutes fat_seek() in all cases where we attempt to seek to current + position. Suggested by Nate Weibley (2016-08-03). + * tools/sethost.sh: Add sethost.sh. This is a script that you can use + to quickly change the host platform from Linux to Windows/Cygwin. + Might save you a lot of headaches (2016-08-03). + * arch/arm/src/tiva: Add tiva PWM lower-half driver implementation. + From Young (2016-08-05). + * drivers/spi/spi_transfer.c: Add a helper function that encapsulates + and manages a sequence of SPI transfers (2016-08-05). + * drivers/spi: Add an SPI character driver that will permit access to + the SPI bus for testing purposes. This driver is a simple wrapper + around spi_transfer() (2016-08-05). + * drivers/wireless: Add MFRC522 RFID ISO14443 and Mifare transceiver + driver. From Alan Carvalho de Assis (2016-08-06). + * configs/stm32f103-minimum: Add board support to MFRC522 driver. From + Alan Carvalho de Assis (2016-08-06). + * arch/renesas: Rename arch/sh to arch/renesas (2016-08-06). + * arch/arm/src/efm32, stm32, stm32l4: STM32 and EFM32 SPI drivers + adopted an incompatible conventions somewhere along the line. The + set the number of bits to negative when calling SPI_SETBITS which had + the magical side-effect of setting LSB first order of bit + transmission. This is not only a hokey way to pass control + information but is supported by no other SPI drivers. This change + three things: (1) It adds HWFEAT_LSBFIRST as a new H/W feature. + (2) It changes the implementations of SPI_SETBITS in the STM32 and + EFM32 derivers so that negated bit numbers are simply errors and it + adds the SPI_HWFEATURES method that can set the LSB bit order, and + (3) It changes all calls with negative number of bits from all + drivers: The number of bits is now always positive and SPI_HWFEATURES + is called with HWFEAT_LSBFIRST to set the bit order (2016-08-08). + * arch/arm/src/stm32: Add missing SPI2 and SPI3 support for STM32F3F3. + Add STM32F37XX DMA channel configuration. For STM32F37XX, + SYSCFG_EXTICR_PORTE defined twice. From Alan Carvalho de Assis + (2016-08-08). + * arch/arm/src/stm32: Make stm32_pwr_enablebkp thread safe. From + Max Neklyudov (2016-08-09). + * arch/arm/src/stm32: SAM3/4 GPIO: Enable peripheral clock for GPIO port + when GPIO is configured as input. The value of a GPIO input is only + sampled when the peripheral clock for the port controller the GPIO + resides in is enabled. Therefore we need to enable the clock even when + polling a GPIO. From Wolfgang Reissnegger (2016-08-09). + * arch/arm/src/tiva: Fix two bugs of tiva pwm lower-half driver + implementation. From Young (2016-08-10). + * sched/group: Explicitly initialize the group tg_exitsem with + sem_init(). The existing logic worked because the correct + initialization value is all zero, but it is better to initialize the + semaphore explicitly (2016-08-10). + * arch/arm/stm32: Fix bad pllmul values for STM32F1XX connectivity line. + STM32F1XX connectivity line supports only x4, x5, x6, x7, x8, x9 and + x6.5 values.

From Vladimir + Komendantskiy (2016-09-20). + * SAM3/4: Fix GPIO pull-up/down code. Enabling the pull-down resistor + while the pull-up resistor is still enabled is not possible. In this + case, the write of PIO_PPDER for the relevant I/O line is discarded. + Likewise, enabling the pull-up resistor while the pull-down resistor + is still enabled is not possible.

From + Young (2016-09-26). + * LPC43xx Serial: There are some small problems in LPC43xx RS485 mode + configuration. In particular: (1) UART0,2,3 do not have DTR pins + (different from UART1), so, Kconfig needs to be adjusted. (2) + lpc43_uart.c in RS485 mode only configures DIR pin, but doesn't enable + pin output for UART0,2,3. (3) should be option to reverse DIR control + pin output polarity.

From Vytautas + Lukenskas (2016-09-30). + * STM32 Ethernet: Correct typo in conditional logic. From Neil Hancock + (2016-10-01). + * sched/pthread and task: When a pthread is started, there is a small + bit of logic that will run on the thread of execution of the new + pthread. In the case where the new pthread has a lower priority than + the parent thread, then this could cause both the parent thread and + the new pthread to be blocked at the priority of the lower priority + pthread (assuming that CONFIG_PRIORITY_INHERITANCE is not selected). + This change temporarily boosts the priority of the new pthread to at + least the priority of the new pthread to at least the priority of the + parent thread. When that bit of logic has executed on the thread of + execution of the new pthread, it will then drop to the correct + priority (if necessary) before calling into the new pthread's entry + point (2016-10-01). + * configs/stm32f103-minimum: Add stm32_bringup support and userled + example to STM32F103 Minimum board.

From Marc Rechté (2016-10-25). + * Add logic to attach peripheral interrupt sources to CPU interrupts + (2016-10-25). + * CHxN channels are always outputs. From Sebastien Lorquet + (2016-10-26). + * sched/semaphore: Within the OS, when a thread obtains a semaphore + count it must call sem_addholder() if CONFIG_PRIORITY_INHERITANCE is + enabled. If a count is available, then sem_wait() calls + sem_addholder(), otherwise it waited for the semaphore and called + sem_addholder() when it eventually received the count. + + This caused a problem when the thread calling sem_wait() was very + low priority. When it received the count, there may be higher + priority threads "hogging" the CPU that prevent the lower priority + task from running and, as a result, the sem_addholder() may be + elayed indefinitely. + + The fix was to have sem_post() call sem_addholder() just before + restarting the thread waiting for the semaphore count. + + This problem was noted by Benix Vincent who also suggested the + solution (2016-10-26). + * configs/stm32f103-minimum: Add RGB LED support on STM32F103 Minimum + board.

It + seemed to be caused by the corrupted or wrong CPSR restored on return + from exception. NuttX restores the context using code like this: + + msr spsr, r1 + + GCC translates this to: + + msr spsr_fc, r1 + + As a result, not all SPSR fields are updated on exception return. + This should be: + + msr spsr_fsxc, r1 + + On some evaluation boards, spsr_svc may have totally invalid value at + power-on-reset.

Thumb + flag in CPSR is not restored back when the context switch occurs while + executing thumb instruction. From Heesub Shin (2016-11-06). + * sched/wqueue: When queuing new LP work, don't signal any threads + if they are all busy. From Heesub Shin (2016-11-06). + * sched/wqueue: Signal sent from work_signal() may interrupt the low + priority worker thread that is already running. For example, the worker + thread that is waiting for a semaphore could be woken up by the signal + and break any synchronization assumption as a result.

From Ramtin Amin (2016-11-14) + * arch/arm/src/samv71: A problem occurred with the SAMV7 USBDEVHS driver + if the USB cable is unplugged while a large amount of data is send over + an IN endpoint using DMA. If the USB cable is plugged in again after a + few seconds it is not possible to send data over this IN endpoint again, + all other endpoints work as expected. + + The problem occurs because if the USB cable is unplugged while an DMA + transfer is in flight the transfer is canceled but the register + SAM_USBHS_DEVDMACTRL is left in an undefined state.

Additionally all pending interrupts are cleared. + + From Stefan Kolb (2016-11-14). + * configs/esp32-core: ESP32 Core v2: Add configuration to supporting + linking NuttX for execution out of IRAM (2016-11-14). + * libc/unistd: sleep() was returning remaining nanoseconds (kind of), + instead the remaining seconds. From Eunbong Song (2016-11-15). + * sched/irq: Fixes for the SMP case: (1) Change order for SMP case in + enter_critical_section: (1) Disable local interrupts BEFORE taking + spinlock and (2) If SMP is enabled, if any interrupt handler calls + enter_critical_section(), it should take the spinlock. (2016-11-15). + * arch/xtensa: Add EXPERIMENTAL hooks to support lazy Xtensa co- + processor state restore in the future (2016-11-16). + * Add some experimental changes to enter/leave_critical_section to + deal with the case where interrupts are disabled only on the local + CPU (2016-11-16). + * sched/irq: Add logic to handled nested calls to + enter_critical_section() from interrupts handlers (with SMP) + (2016-11-16). + * drivers/timer: Remove the timer driver TIOC_SETHANDLER IOCTL call. + This calls directly from the timer driver into application code.

From + Sebastien Lorquet (2016-11-18). + * drivers/net: Add option to use low-priority work queue to all drivers + in drivers/net. Not yet added to all architecture-specific network + drivers (2016-11-18). + * sched/wdog: Most interrupt handling logic interacts with tasks via + standard mechanism such as sem_post, sigqueue, mq_send, etc. These all + call enter_critical_section and are assumed to be safe in the SMP case. + + But certain logic interacts with tasks in different ways. The only one + that comes to mind are wdogs. There is a tasking interface that to + manipulate wdogs, and a different interface in the timer interrupt + handling logic to manage wdog expirations. + + In the normal case, this is fine. Since the tasking level code calls + enter_critical_section, interrupts are disabled an no conflicts can + occur. But that may not be the case in the SMP case. Most + architectures do not permit disabling interrupts on other CPUs so + enter_critical_section must work differently: Locks are required to + protect code. + + So this change adds locking (via enter_critical section) to wdog + expiration logic for the case if the SMP configuration + (2016-11-18). + * SAM3/4: Add delay between setting and clearing the endpoint RESET bit + in sam_ep_resume(). We need to add a delay between setting and + clearing the endpoint reset bit in SAM_UDP_RSTEP. Without the delay the + USB controller will (may?) not reset the endpoint. If the endpoint is + not being reset, the Data Toggle (DTGLE) bit will not to be cleared + which will cause the next transaction to fail if DTGLE is 1. If that + happens the host will time-out and reset the bus. Adding this delay + may also fix the USBMSC_STALL_RACEWAR in usbmsc_scsi.c, however this + has not been verified yet.

In that case, the calculation was returning + millisecond accuracy. That is not good when the timer accuracy is < 1 + msec. From Rajan Gill (2016-11-19). + * sched/task: task_restart() test not supported on SMP systems. This is + not fully implemented (2016-11-19). + * This commit adds a new internal interfaces and fixes a problem with + three APIs in the SMP configuration. The new internal interface is + sched_cpu_pause(tcb). This function will pause a CPU if the task + associated with 'tcb' is running on that CPU. This allows a different + CPU to modify that OS data stuctures associated with the CPU. When the + other CPU is resumed, those modifications can safely take place. The + three fixes are to handle cases in the SMP configuration where one CPU + does need to make modifications to TCB and data structures on a task + that could be running running on another CPU. Those three cases are + task_delete(), task_restart(), and execution of signal handles. In + all three cases the solutions is basically the same: (1) Call + sched_cpu_pause(tcb) to pause the CPU on which the task is running, + (2) perform the necessary operations, then (3) call up_cpu_resume() to + restart the paused CPU (2016-11-20). + * task_restart: Make sure new task starts with pre-emption disabled and + not in a critical section (2016-11-21). + * Fix a typo in a spinlock macro (2016-11-21). + * Spinlocks: Added capability to provide architecture-specific memory + barriers.

From Ramtin + Amin (2016-11-28). + * Add tools/showsize.sh (2016-11-28). + * configs/misoc: Add a sample directory containing generated sources. + This is really only useful for performing test builds.

An Acknowledge-Error will occur every time no other CAN Node + acknowledges the message sent. This will also occur if the device is + not connected to the can-bus. The CAN-Standard declares, that the Chip + has to retry a given message as long as it is not sent successfully (or + it is not cancelled by the application). Every time the chip tries to + resend the message an Acknowledge-Error-Interrupt is generated. At high + baud rates this can lead in extremely high CPU load just for handling + the interrupts (and possibly the error handling in the application). To + prevent this Interrupt-Flooding we disable the ACKE once it is seen as + long we didn't transfer at least one message successfully. From Frank + Benkert (2016-12-13). + * i.MX6: Remove non-cached, inter-cpu memory region. Not a useful + concept (2016-12-13). + * minnsh Configurations: Remove minnsh configurations and support logic: + up_getc() and lowinstream. This was an interesting exercise to see + just how small you could get NuttX, but otherwise it was not useful: + (1) the NSH code violated the OS interface layer by callup up_getc and + up_putc directly, and (2) while waiting for character input, NSH would + call up_getc() which would hog all of the CPU. Not a reasonable + solution other than as a proof of concept (2016-12-13). + * Calypso Boards: Remove all Calypso board configurations (2016-12-13). + * Calypso: Remove Calypso architecture support and support for Calypso + SERCOMM driver (2016-12-13). + * ESP32 core v2: Two changes (1) flushes the UART TX buffer in the esp32 + serial shutdown routine. The ROM bootloader does not flush the FIFO + before handing over to user code, so some of this output is not + currently seen when the UART is reconfigured in early stages of + startup. And changes the openocd config file's default flash voltage + from 1.8V to 3.3V. This is not necessary right now, but may save some + hard-to-debug moments down the track (3.3V-only flash running at 1.8V + often half-works and does weird things...).

It is possible that a context switch + occurs after I2C registers are read but before elapsed time is saved + in stm32_i2c_sem_waitstop(). It is then possible that the registers + were read only once with "elapsed time" equal 0. When scheduler + resumes this thread it is quite possible that now "elapsed time" will + be well above timeout threshold. In that case the function returns + and reports a timeout, even though the registers were not read + "recently". Fix this by inverting the order of operations in the loop + - save elapsed time before reading registers. This way a context + switch anywhere in the loop will not cause an erroneous "timeout" + error. From Freddie Chopin (2017-03-10). + * pthreads: Fix pthread_mutexattr_init(). It was not initializing the + protocol field when priority inheritance is enabled (2017-03-10). + * Priority inheritance: When CONFIG_SEM_PREALLOCHOLDERS==0, there is + only a single, hard-allocated holder structure. This is problem + because in sem_wait() the holder is released, but needs to remain in + the holder container until sem_restorebaseprio() is called. The call + to sem_restorebaseprio() must be one of the last things the + sem_wait() does because it can cause the task to be suspended. If in + sem_wait(), a new task gets the semaphore count then it will fail to + allocate the holder and will not participate in priority + inheritance.

The call to + sem_restorebaseprio_task context switches in the + sem_foreachholder(sem, sem_restoreholderprioB, stcb); call prior to + releasing the holder. So the running task is left as a holder as is + the started task. Leaving both slots filled thus failing to perform + the boost/or restoration on the correct tcb. This PR fixes this by + releasing the running task slot prior to reprioritization that can + lead to the context switch. To faclitate this, the interface to + sem_restorebaseprio needed to take the tcb from the holder prior to + the holder being freed. In the failure case where sched_verifytcb + fails it added the overhead of looking up the holder. There is also + the additional thunking on the foreach to get from holer to + holder->tcb. An alternate approach could be to leve the interface + the same and allocate a holder on the stack of sem_restoreholderprioB + copy the sem's holder to it, free it as is done in this pr and and + then pass that address sem_restoreholderprio as the holder. It could + then get the holder's tcb but we would keep the same sem_findholder + in sched_verifytcb. From David Sidrane (2017-03-15). + * ARM: Remove redundant interrupt stack coloring.

From Mateusz Szafoni + (2017-03-25). + * stm32/Kconfig: Update COMP and OPAMP definitions. From Mateusz + Szafoni (2017-03-26). + * pthreads: Add more robustness characteristics: pthread_mutex_lock() + and trylock() will now return EOWNERDEAD if the mutex is locked by a + thread that no longer exists. Add pthread_mutex_consistent() to + recover from this situation (2017-03-26). + * pthread: Fix return value of pthread_give/takesemaphore(). Add + option to pthread_takesemaphore to ignore EINTR or not (2017-03-26). + * pthreads: Partial implementation of final part of robust mutexes: + Keep list of all mutexes held by a thread in a list in the TCB + (2017-03-26). + * when pthread exits or is cancelled, mutexes held by thread are marked + inconsistent and the highest priority thread waiting for the mutex is + awakened (2017-03-26). + * pthreads: Add a configuration option to disable robust mutexes and + revert to the traditional unsafe mutexes (2017-03-26). + * pthread mutexes: Add option to support both unsafe and robust + mutexes via pthread_mutexattr_get/setrobust() (2017-03-26). + * pthread mutexes: Finish logic to support configuration mutex + robustness (2017-03-27). + * Rename CONFIG_MUTEX_TYPES to CONFIG_PTHREAD_MUTEX_TYPES (2017-03-27). + * Make sure that CONFIG_PTHREAD_MUTEX_ROBUST=y is selected every + configuration that enabled pthreads (2017-03-27). + * Add syscall support for pthread_mutex_consistent() (2017-03-27). + * Include wcstold in C++ cwchar header file. From Alan Carvalho de + Assis (2017-03-27). + * AT86RF23x: Clean-up, standardize lower half interface. Take + advantage of new OS features for interrupt parameter passing + (2017-03-27). + * MRF24J40: Take advantage of new OS features for interrupt parameter + passing (2017-03-27). + * lcd/: PCF8574 backpack logic needs to include poll.h + CONFIG_DISABLE_POLL is not set (2017-03-27). + * drivers/analog: Add driver for the LTC1767L ADC. From Martin + Lederhilger (2017-03-28). + * realloc(): When realloc() has to fall back to calling malloc(), size + including overhead was being provided to malloc(), causing a slightly + larger allocation than needed. Noted by initialkjc@yahoo.com + (2017-03-28). + * Fix PTHREAD_MUTEX_INITIALIZER which was not updated with last mutex + changes. From Jussi Kivilinna (2017-03-28). + * STM32 F7: Add stm32 RNG support. This is copied from stm32l4. + Tested on STM32F746ZG board. From Juha Niskanen (2017-03-29). + * STM32 RNG: Fix semaphore initial value and disable priority + inheritance. From Juha Niskanen (2017-03-29). + * Fix an assertion noted by Jussi Kivilinna. This was a consequence of + the recent robust mutex changes. If robust mutexes are selected, + then each mutex that a thread takes is retained in a list in threads + TCB. If the thread exits and that list is not empty, then we know + that the thread exitted while holding mutexes. And, in that case, + each will be marked as inconsistent and the any waiter for the thread + is awakened. For the case of pthread_mutex_trywait(), the mutex was + not being added to the list! while not usually a fatal error, this + was caught by an assertion when pthread_mutex_unlock() was called: + It tried to remove the mutex from the TCB list and it was not there + when, of course, it shoule be. The fix was to add + pthread_mutex_trytake() which does sem_trywait() and if successful, + does correctly add the mutext to the TCB list. This should + eliminated the assertion (2017-03-29). + * 6LoWPAN: IEEE802.15.4 MAC driver will need a special form of the + network device structure to manage fragmentation of the large packet + into frames (2017-03-29). + * wireless/ieee802154: Adds MAC character driver structure. + Nonfunctional. From Anthony Merlino (2017-03-29). + * configs/clicker2-STM32: Adds logic to create an 802.15.4 MAC and + register a character driver. From Anthony Merlino (2017-03-29). + * net/local: connect: Fix warning with gcc-arm-none-eabi-5-2016q1. + Using compiler from gcc-arm-none-eabi-5-2016q1 toolchain: + + gcc version 5.3.1 20160307 (release) [ARM/embedded-5-branch revision 234589] (GNU Tools for ARM Embedded Processors) + + gives error: + + local/local_connect.c:188:7: error: '_local_semtake' is static but used in inline function 'local_stream_connect' which is not static [-Werror] + + this is due to compiler enforcing ISO/IEC 9899:1999 6.7.4.3: "An + inline definition of a function with external linkage shall not + contain a definition of a modifiable object with static storage + duration, and shall not contain a reference to an identifier with + internal linkage." Fix by making inlined caller to have internal + linkage as well. From Juha Niskanen (2017-03-30). + * Add entropy pool and strong random number generator. Entropy pool + gathers environmental noise from device drivers, user-space, etc., + and returns good random numbers, suitable for cryptographic use. + Based on entropy pool design from *BSDs and uses BLAKE2Xs algorithm + for CSPRNG output. Patch also adds /dev/urandom support for using + entropy pool RNG and new 'getrandom' system call for getting + randomness without file-descriptor usage (thus avoiding + file-descriptor exhaustion attacks). The 'getrandom' interface is + similar as 'getentropy' and 'getrandom' available on OpenBSD and + Linux respectively. From Jussi Kivilinna (2017-03-30). + * Change STM32 tickless to use only one timer. From Konstantin + Berezenko (2017-03-30). + * drivers/sensors: Add driver for ST HTS221 humidity sensor. From Juha + Niskanen (2017-03-30). + * HTS221 driver: Modify to use new interrupt parameter passing hooks + (2017-03-31). + * drivers/sensors: Add driver for ST LPS25H pressure sensor.

Tested + with earlier version of NuttX; with current version checked that it + compiles. Via Juha Niskane (2017-03-31). + * Add user-space networking stack API (usrsock). User-space networking + stack API allows user-space daemon to provide TCP/IP stack + implementation for NuttX network. Main use for this is to allow use + and seamless integration of HW-provided TCP/IP stacks to NuttX. For + example, user-space daemon can translate /dev/usrsock API requests to + HW TCP/IP API requests while rest of the user-space can access + standard socket API, with socket descriptors that can be used with + NuttX system calls. From Jussi Kivilinna (2017-03-31). + * STM32F7: Add support for LSE RTC and enable RTC subseconds. From + Jussi Kivilinna (2017-03-31). + * TCP/IPv6: Fix a compile issue when IPv6, but not IPv4 is enabled + (2017-03-31). + * net/: Fix MULTINIC/MULTILINK selection when 6LoWPAN selected + (2017-03-31). + * net/: Permit net/neighbor to build when IPv6 is defined, but not + Ethernet.

From Alan Carvalho + de Assis (2017-04-06). + * STM32F7: Serial: Add interface to get uart_dev_t by USART number, + stm32_serial_get_uart. From Jussi Kivilinna (2017-04-06). + * STM32F7: Default CONFIG_STM32F7_DMACAPABLE to 'n'. STM32F7 does not + have CCM RAM but DTCM, so this option does not need to enabled. DTCM + RAM is DMA-able through CPU AHBS bus. From Jussi Kivilinna + (2017-04-06). + * STM32F7: Fix UART7 and UART8 IFLOWCONTROL options. From Jussi + Kivilinna (2017-04-06). + * STM32F7: Add warning for RXDMA + IFLOWCONTROL combination. + Combination of RXDMA + IFLOWCONTROL does not work as one might + expect. Since RXDMA uses circular DMA-buffer, DMA will always keep + reading new data from USART peripheral even if DMA buffer underruns. + Thus this combination only does following: RTS is asserted on USART + setup and deasserted on shutdown and does not perform actual RTS + flow-control. Data loss can be demonstrated by doing long up_mdelay + inside irq critical section and feeding data to RXDMA+IFLOWCONTROL + UART. From Jussi Kivilinna (2017-04-06). + * sim/sixlowpan: Now supports apps/examples/udpblaster too (2017-04-06). + * SAMV7: Watchdog: Fix Forbidden Window Value. According the Datasheet + the WDD Value is the lower bound of a so called Forbidden Window and + to disable this we have to set the WDD Value greater than or equal to + the WDV Value. This seems to be a bug in the datasheet. It looks + like we have to set it to a greater value than the WDV to really + disable this Thing. When triggering the Watchdog faster than the + (very slow) clock source of the Watchdog fires, this Forbidden Window + Feature resets the System if WDD equals to WDV. This Changeset + disables the Forbidden Window by setting the WDD Value to the Maximum + (0xfff) Value possible. From Frank Benkert (2017-04-06). + * RTC: Add interface for check if RTC time has been set. New interface + allows checking if RTC time has been set. This allows to application + to detect if RTC has valid time (after reset) or should application + attempt to get real time by other means (for example, by launching + ntpclient or GPS). From Jussi Kivilinna (2017-04-06). + * 6LoWPAN: Add network IOCTL support to set the node address + (2017-04-06). + * EFM32 I2C: Fix timeout calculation.

Same as with most other newer board + configurations (2017-04-09). + * net procfs: Some long lines were being generated that cause + buffer-related problems and corrupted output (2017-04-09). + * stm32 COMP: Logic in stm32_comp.h must be configured on + CONFIG_STM32_COMP or otherwise it causes an error via #error on every + platform without COMP support (2017-04-09). + * Photon: Add logic to automatically mount the procfs file system on + startup. Fix some LED-related configuration conflicts (2017-04-09). + * Buttons: Correct some comments left after last button-related + change: 32- vs 8-bit bit set (2017-04-09). + * pthread: Use cancel cleanup handlers in rwlock.

In the + case that a serial device is opened with the flag O_NONBLOCK the + function uart_close(…) blocks until all data in the buffer is + transmitted. The function close(…) called on an handle opened with + O_NONBLOCK should not block. The problem occurred with a CDC/ACM + device. From Stefan Kolb (2017-05-10). + * mtd/config: erase block between block read and write.

Additional trailing characters could be ANSI escape + sequence to reset state that message setups.

This could be avoided by not flushing on + '\n' but only if IOB is full and/or at end of vsyslog. Would this + make sense?. From Jussi Kivilinna (2017-05-11). + * Syslog: Need inclusion of errno.h for fix building with + CONFIG_SYSLOG_TIMESTMAP=y (2017-05-11). + * mtd: Build RAMTRON and AT45DB drivers only if selected.

TODO: This is not a perfect solution. readahead + support has similar issues. From Juha Niskanen (2017-05-11). + * STM32L4: port stm32l4_serial_get_uart function from STM32F7. From + Juha Niskanen (2017-05-12). + * syslog: Avoid flushing syslog_stream buffer, if possible, until + lib_vsprintf() completely parses the format. This assures that the + flush will flush the entire output, even data that may potentially + follow the linefeed. And, in that case, it cannot be interleaved + with other devug output. Suggested by Jussi Kivilinna (2017-05-12). + * syslog: There is yet another place where the output can get split. + That is in syslog_dev_write(): It will break up the stream to insert + a CR before the LF. This can that can be avoid be generating the + CR-LF sequence in the buffer and then detecting and ignoring valid + CR-LF sequences, rather than expecting syslog_dev_write() to insert + the CR in this case. I don't like the idea that syslog_dev_write() + still scans the entire output buffer to expand CR-LF sequence. This + seems really wasteful, especially in this case where we can be sure + that the is no CR or LF without a matching LF or CR. Bu, I think, + the existing behavior in syslog_dev_write() must be retained because + it is needed in other contexts (2017-05-12). + * Bitbucket Issue 47: Some of last syslog changes needed to be + condition on #ifdef CONFIG_SYSLOG_BUFFER in order to be built without + syslog buffering enabled (2017-05-12). + * Move CAN subsystem to its own directory and put device drivers + there.

From Juha Niskanen (2017-05-15). + * drivers: rename newly introduced up_i2creset to I2C_RESET. From + Juha Niskanen (2017-05-15). + * TCP: An RST received during the 3-way handshake requires a little + more clean-up (2017-05-15). + * STM32 CAN: I had the problem that the transmit FIFO size (= actual + elements in FIFO) was slowly increasing over time, and was full after + a few hours. The reason was that the code hit the line + "canerr("ERROR: No available mailbox\n");" in stm32_cansend, so + can_xmit thinks it has sent the packet to the hardware, but actually + has not. Therefore the transmit interrupt never happens which would + call can_txdone, and so the size of the FIFO size does not decrease. + The reason why the code actually hit the mentioned line above, is + because stm32can_txready uses a different (incomplete) condition than + stm32can_send to determine if the mailbox can be used for sending, + and thus can_xmit forwards the packet to stm32can_send. + stm32can_txready considered mailboxes OK for sending if the mailbox + was empty, but did not consider that mailboxes may not yet be used if + the request completed bit is set - stm32can_txinterrupt has to + process these mailboxes first. Note that I have also modified + stm32can_txinterrupt - I removed the if condition, because the CAN + controller retries to send the packet until it succeeds. Also if the + condition would not evaluate to true, can_txdone would not be called + and the FIFO size would not decrease also. From Lederhilger Martin + (2017-05-16). + * drivers/bch: BCH character driver bch_ioctl() always returns -ENOTTY + for DIOC_GETPRIV command. It should returns OK if DIOC_GETPRIV + command succeeds. From EunBong Song (2017-05-16). + * There can be a failure in IOB allocation to some asynchronous + behavior caused by the use of sem_post(). Consider this scenario: + (1) Task A holds an IOB.  There are no further IOBs.  The value of + semcount is zero. Task B calls iob_alloc().  Since there are not + IOBs, it calls sem_wait().  The value of semcount is now -1. (2) + Task A frees the IOB.  iob_free() adds the IOB to the free list and + calls sem_post() this makes Task B ready to run and sets semcount to + zero NOT 1.  There is one IOB in the free list and semcount is zero. + When Task B wakes up it would increment the sem_count back to the + correct value. (3) But an interrupt or another task runs occurs + before Task B executes.  The interrupt or other tak takes the IOB off + of the free list and decrements the semcount.  But since semcount is + then < 0, this causes the assertion because that is an invalid state + in the interrupt handler. So I think that the root cause is that + there the asynchrony between incrementing the semcount. This change + separates the list of IOBs: Currently there is only a free list of + IOBs. The problem, I believe, is because of asynchronies due + sem_post() post cause the semcount and the list content to become out + of sync. This change adds a new 'committed' list: When there is a + task waiting for an IOB, it will go into the committed list rather + than the free list before the semaphore is posted. On the waiting + side, when awakened from the semaphore wait, it will expect to find + its IOB in the committed list, rather than free list. In this way, + the content of the free list and the value of the semaphore count + always remain in sync (2017-05-16). + * stm32_serial: Fix freezing serial port.

We use this feature to switch + between one in normal and up to three CDCACMs in maintenance boot. + The control path starts in boardctl.c where the configuration for the + device is constructed. There are still a few issues which I'll ask + you to have a look at before this beast can be merged. (1) To be + able to construct the data dynamically I have changed some + USB-Structs to be packed. Maybe there are additional structs to + change (just for completeness – not for current functionality). (2) + I've added the Macro COMPILE_TIME_ASSERTION two times (in + usbmsc_desc.c and in cdcacm_desc.c) to stay private. Maybe you’ll + find a better place. It’s used to check the size of the structs + against the assumptions. (3) I've changed the interface for some + USB-Functions to receive also the dynamic configuration. Maybe this + can be done more elegant. (4) The original NuttX (without the patch) + seems to have problems with a Composite device holding a CDCACM and + an MSC. The USB SET CONFIGURATION request does not to work at all. + This makes the test fail under Windows and under Linux.

However, when intercepted by the + hub, the uncompressed address does not know the short address of the + recipient and instead uses the short address of the hub.

From Jeff + (2017-07-28). + * We discovered a problem with the samv7 mcan driver which results, + under some circumstances, in a very high CPU load. The problem + occurs, and is easily reproducible, if the device is connected to a + CAN network with a wrongly configured CAN speed (baud rate). In our + tests we set the CAN speed of the device to 1000000 and the speed of + the other CAN nodes to 500000. The device is restarted and sends a + CANopen "bootup message" to the CAN network. This results in huge + amount of errors messages on the CAN bus, probably because of the CAN + feature for acknowledging error messages. The error messages can’t + be read by the device because of the misconfigured CAN speed, instead + the CAN chip reports lots of errors, which are reported to the + application which uses the CAN driver (CONFIG_CAN_ERRORS is enabled). + The CAN errors are reported from the CAN chip via interrupts and thus + the interrupt load is very high in this scenario. To fix the problem + the driver now disables each RX error interrupt after it is occurred. + The RX error interrupts are turned back on if at least one CAN + message is received successfully. From Stefan Kolb (2017-07-28). + * tcdrain implementation based on a new term ioctl. From Sebastien + Lorquet (2017-07-28). + * Spirit Network Driver: Create build directories, Add radio + initialization, interrupt handling logic, packet transmissin and + reception logic.

From Titus von Boxberg (2017-07-28). + * STM32 F7: No board specific dithering values used; corrected + dithering init. Corrected LIPOS/LIPCR calculation. Change only + polarity bits in LTDC_GCR. From Titus von Boxberg (2017-07-29). + * STM32_RCC_DCKCFGR2 has nothing to do with PLLI2S; PLLI2S is not + dependent on LTDC, instead on SAICLK1/2 generated from PLLI2S. From + Titus von Boxberg (2017-07-29). + * To use an external oscillator module (not just a crystal) with the + STM32F4, one needs to enable the HSEBYP bit in the RCC_CR register. + This change allows an integrator to define STM32_RCC_CR_HSEBYP in + their board.h file if they want this configuration. From Jeff + (2017-07-30). + * 6LoWPAN PktRadio: Some initial changes to support raw packet radios + without IEEE 802.15.4 with 6LoWPAN. Add missing MetaData-related + prototypes and initialization logic. Perform a major renaming to + make room in the 6LoWPAN name space for packet radios. Replace + metadata input parameter type from struct ieee802154_data_ind_s to + void*. This permits radios with different MAC metadata to interact + with 6LoWPAN. Includes many changes to handle variable length radio + addresses. No longer just short and exteneded; any length.Remove + explicit type struct ieee802154_frame_meta_s from derive interface + methods. Replace with a opaque void * type so that other radio meta + data structures may use the interfaces. Add a new radion interface + to get properties of the radio. Spirit: Finish packet I/O interface + with the network. Fix case where source and destination IP address + were backward. Fix some compile issues when star topology support is + enabled. Condition out some types that depend on definitions that are + only available with 6LoWPAN is enabled (2017-07-30). + * STM32L4 PWR: correct PWR_SR2 REGLPS and REGLPF bits, add port I + registers.

From + Boris Astardzhiev (2017-08-04). + * Spirit1 network driver: Correct setting of the length width field; + Add multicast and broadcast addresses to radio properties. Convert + network driver to use STack packets vs. Basic packets. We need to + use the STack packets in order to provide the source address + (2017-08-04). + * tools/mkdeps.c: Eliminate a warning. MAX_PATH may already be defined + in included system files. From Jeff (2017-08-04). + * Spirit1 network drvier: Increase number of retries if there is no + acknowledgement; Add interrupt handling for the case where the max + number of retries expires. Fix some badly implemented queue + management code. With these changes the basic UDP and TCP tests + work. Enable AutoACK, TX retries, and RX timeouts in the network + driver (2017-08-04). + * B-L475E-IOT01A: Make spirit-6lowpan configuration match what is + currently under test: Enable multicast, broadcast, but disable CRC + support. Currently CRCs are not working right (2017-08-04). + * b-l475e-iot01a: Add configurations to support a star topology + (2017-08-05). + * Spirit + 6LoWPAN: In STAR configuration, Spirit must use a + configured well known hub address. 6LoWPAN cannot assume that the + PAN coordinator is the STAR hub; it must ask the radio to provide it + with the address of the star hub (2017-08-05). + * IEEE 802.15.4 network driver: Fix more compile issues that only show + up when CONFIG_NET_STARPOINT is defined (2017-08-05). + * STM32F746-Disco: Add ADC3 support. From Ivan Ucherdzhiev + (2017-08-05). + * Spirit Network Driver: Attempts to eliminate RX FIFO errors. Reduce + max packet length to avoid an errata.

Also + reviewed and cleaned up all error handling logic (2017-08-06). + * sched/: Fix return value in sched_setaffinity(). From Masayuki + Ishikawa (2017-08-07). + * Spirit bugfixes: Was hanging occasionally because there was no + mechanism to restart the poll timer if poll was not performed because + Spirit ws busy. Fixed by not checking if Spirit is busy. The TX + poll can be performed asynchronouly while spirit is busy; any + outgoing data will queued until Spirit is ready. Fixed handling of a + timeout condition. Failure to transmition to the TX state would fail + (timeout) if in a race condition Spirit already committed to the RX + state. The driver needs to recover the state properly and avoid + debug assertions in this event (2017-08-07). + * STM32 USB: I'm working on bringing up USB full-speed support on + STM32F405.  My board does not include a USB power switch, VBus + sensing, over current detection, or ID pin. This commit add a + config STM32_OTGFS_VBUS_ CONTROL which lets us selectively disable + VBus sensing and control.  I also sneaked in a change to disable the + configgpio call for the ID pin, which is only used in OTG mode which + isn't supported yet.  The only pins that need to be initialized + should be OTGFS_DP and OTGFS_DM. These changes let a USB mouse + enumerate on my platform if it's plugged in on power-up.  Plugging, + unplugging, clicking, or moving the mouse cause NSH to stop + responding.  Because I'm using the ramlog, I don't have useful debug + messaging yet, so there's a lot more work I have to do to + troubleshoot it or get my JTAG debugging set up, but these patches + shouldn't hurt anything.  I'm hoping my issue is something simple I + overlooked in configuration. From Jeff (2017-08-07). + * I discovered while working on the SAMV7 mcan driver that the + implementation of the CAN error handling is suboptimal. In the + current implementation the many errors are implemented as pending + errors. But those errors are not pending, the errors occurred and + are gone directly afterwards. This commit changes the described + behavior and simplifies the handling of CAN errors. From Stefan Kolb + (2017-08-07). + * IPv6: Remove comparisons to the address with all ones set. IPv6 + does not support broadcast addresses and certainly not in that form. + Replace with multicast addresses beginning with 0xff02 (2017-08-07). + * ICMPv6: Support source link-layer address option in RA.

From Masayuki Ishikawa (2017-08-09). + * Update NSH documentation to show new usage for addroute and delroute + (2017-08-10). + * cwchar: Use CONFIG_LIBC_WCHAR to only export the wc/mb functions. + When a build does not want to use wide or multibyte char + CONFIG_LIBC_WCHAR is not set. Therefore we should to only export the + wc/mb functions when defined. Regardless of the stat of + CONFIG_LIBC_WCHAR the non mb/wc definitions such as mbstate_t, + wint_t, wctype_t need to be exported. From David Sidrane + (2017-08-10). + * inet_ntop: Was printing negative values for fields >127 + (2017-08-11). + * procfs: Add support for routing tables at proc/net/route + (2017-08-11). + * Unify GCC/Clang config. From Goran Mekić (2017-08-12). + * procfs routing table: Don't print the IPv4 routing table header if + the table is empty. Fix a couple of places where CONFIG_NET_IPv4 was + used wehre IPv6 was intended (not noticed now because I am testing + with both enabled) (2017-08-12). + * C++: Compilation with recent C++ compiler needs an overloaded delete + operator that includes a size_t size argument (2017-08-12). + * ARM: The older ARM7 and ARM9 configurations were determining CFLAGS + based on the GCC version 4.x.x or not. That needx to be extended for + 5.x.x and 6.x.x which also behave like 4.x.x (2017-08-12). + * STM32F7: Some STM32F7 builds failed in build testing due to undefined + STM32_SRAM1_BASE.

Updated + comment to proper refernce manual for STM32F7 not STM32F4. Added + stm32_dmacapable input paramaters documentation. From David Sidrane + (2017-08-17). + * STM32 F7: DMA add dcache alignment check in stm32_dmacapable. In the + case dcache write-buffed mode is used (not write-through) buffer + alignment is required for DMA transfers because a) + arch_invalidate_dcache could lose buffered writes data and b) + arch_flush_dcache could corrupt adjacent memory if the maddr and the + mend+1, the next next address are not on ARMV7M_DCACHE_LINESIZE + boundaries. From David Sidrane (2017-08-17). + * STM32 F7: SDMMC remove widebus limitation on DMA. There is no + documantation for the STM32F7 that limits DMA on 1 bit vrs 4 bit + mode.

Add configs/sim configuration for testing + (2017-08-19). + * STM32 COMP: add default INM configuration and some missing + COMP1,3,5,7 code. From Mateusz Szafoni (2017-08-20). + * 6LoWPAN/PF_IEEE802154: Created radiodev.h and renamed various + structures to provide a better separation between 6LoWPAN networking + and PF_IEEE802154 address family (2017-08-20). + * STM32 DAC: fix some configuration logic. When STM32_NDAC is greather + than 1, then second channel is always DAC1OUT2. From Mateusz Szafoni + (2017-08-20). + * PF_IEEE802154 address family: IEEE 802.15.4 network device: Make + same changes as per loopback device so that it will build with + PF_IEEE802154 but without 6LoWPAN. More fixes to device registration + and to IEEE 802.15.4 loopback driver for PF_IEEE802154 without + 6LoWPAN. Changes to conditional compilation so that PF_IEEE802154 + can build without 6LoWPAN (2017-08-20). + * drivers/net/tun.c: Currently cannot support TAP mode unless Ethenet + is enabled (2017-08-20). + * PktRadio loopback driver: Fix compile problem by removing + inappropriate const storage class (2017-08-20). + * Networking: Remove driver based backlog support. This affects the + entire network, but is used by only one driver. The only supported + RX backlog is now via common read-ahead buffering (2017-08-21). + * PF_IEEE802154 socket family: (1) Improve some backlog counting + logic; add more assertions to catch cases where the backlog count + might deviate from the actual backlog. (2) Add a maximum backlog + option. This will prevent overrun of the RX frame queue if many + frames are received from the radio, but no application is receiving + the queued data. (3) On input, there may be a list of frames + provided, not just one. When closed() and connection is freed, also + need to free any frames remaining in the RX queue (2017-08-21). + * Network procfs: Add support for network procfs statistics when + nothing is enabled but PF_IEEE802154 (2017-08-21). + * STM32 DAC: Add support for HRTIM triggering.

From Juha Niskanen + (2017-08-22). + * drivers/lcd: ssd1306: (1) Separate lcd_dev_s setup to separate + object. g_oleddev takes 1 KiB because framebuffer and was allocated + to .data section because of lcd_dev_s function pointer setup. Move + lcd_dev_s setup out, so that g_oleddev goes to .bss and avoid wasting + ROM. (2) Fix memory corruption caused by ssd1306_getrun(). + ssd1306_getrun was writing one extra byte (with value 0) past target + buffer when pixlen is multiple of 8. When pixlen was not multiple of + 8, last byte of buffer was fully cleared, instead of modifying only + the (pixlen % 8) bits of last byte. (3) Add support for board power + control. ThingseeOne has regulator for controlling display power + on/off. Patch adds support for board based power control to SSD1306 + driver. (4) Add DD-12864WO-4A/SSD1309 support to SSD1306 driver. + From Jussi Kivilinna (2017-08-22). + * Network procfs: procfs/net_procfs_route.c building error occur if + CONFIG_NET_ROUTE is enabled. Fix suggested by Aleksandr Kazantsev + (2017-08-22). + * Networking: Fix ompile error if Unix domain sockets selected + (2017-08-23). + * STM32L4 TIM: TIM15,16,17 are always in APB2. From Juha Niskanen + (2017-08-25). + * STM32L4 DAC: report transfer as completed in DMA callback. Without + this even O_NONBLOCK writes block the calling task if DAC was using + DMA. From Juha Niskanen (2017-08-25). + * STM32L4 COMP: comparators share RCC enable bit with SYSCFG. From + Juha Niskanen (2017-08-25). + * power: add driver for TI bq2429x battery charger. TODO: Untested. + Does not have poll() support. From Juha Niskanen (2017-08-25). + * 6LoWPAN: The original, Contiki-based design used only a single + buffer for reassemblying larger packets. This could be a problem + issue for hub configurations which really need the capability + concurrently reassemble multiple incoming streams concurrently. + These was also a design issue in that the reassembly buffer could be + corrupted by outgoing packets. The design was extended to support + multiple reassembly buffers, each associated with the reassembly tag + and source address. This assures that there can be be no corruption + of the reassembly once it has started (2017-08-26). + * Simulator: Adds necessary functionality to build Simulator under ARM + Linux. Tested only on Raspberry3. Currently setjmp/longjmp do not + save/restore floating point registers. From Nickolay Semyonov + (2017-08-26). + * fs: FS_AUTOMOUNTER should depend on SCHED_LPWORK.

From Juha Niskanen (2017-08-28). + * work_queue() must cancel existing work prior to queuing new work, + otherwise the work queue list structure can become corrupted. + Problem noted by Pascal Speck (2017-08-28). + * STM32 HRTIM: Add DMA configuration. From Mateusz Szafoni + (2017-08-28). + * Networking: Move TCP specific files from inet/ to tcp/. There is + another TCP-specific logic in inet/ that should be moved sometime, + but those are more entangled (2017-08-29). + * Networking: TCP disconnection callbacks are not retained in a list. + This will support multiple callbacks per lower-level TCP connection + structure. That is necessary for the cae where a socket is dup'ed + and shares the same lower-level connection structure. NOTE: There + still needs to be a call to tcp_start_monitor() when the socket is + dup'ed (2017-08-29). + * Networking: Start the network monitor for a socket when a TCP socket + is dup'ed (2017-08-29). + * Networking: A placeholder for some missing logic in the previous + change related to monitoring network status for dup'ed sockets. If + one of the dup'ed socket's is closed, then network monitor resources + associated with that one socket must be recovered. Also, in the + event that socket is being used on one thread, but then closed on + another, any threads waiting for events from the socket should be + informed of the closure. That latter requirement is not implemented + because current data structures do not support it (2017-08-29). + * Networking: Clean up some naming that has bothered me for a long + time... There are no interrupts and no interrupt handlers in the + network. There are events and event handler (there used to be + interrupt logic in there years ago but that is long, long gone) + (2017-08-29). + * configs: update STM32L4 configs for ADC changes. From Juha Niskanen + (2017-08-30). + * configs: update STM32L4 configs for ADC changes. From Juha Niskanen + (2017-08-30). + * Porting Guide: Add usage tip for reading CAN messages from the CAN + driver without losing message (2017-08-30). + * Networking: socket dup() conditional operation was missing the test + for the condition (2017-08-30). + * ARMv7-M syscall logic: Clear bit 0 in PC settings. Bit 0 is the + thumb mode indication and should not be set in the PC. This extra + bit has not caused problems in the past, but seeing it set in the PC + is unnerving (2017-08-30). + * Networking: Fix a race condition. The accept() operation is + performed with the network locked. However, the network is unlocked + BEFORE the connected state is set. Therefore, a context switch may + occur and the socket may no longer be connected when it is marked so. + Noted by Pascal Speck (2017-08-31). + * Work queue: In a recent change for a problem noted by Pascal Speck, + it was noted (again by Pascal Speck) that the cancellation of + existing work and replacement with new work must be atomic. Thanks, + Pascal (2017-08-31). + * LPC43xx: Modify up_allocate_(k)heap() to support PROTECTED mode. + From Alan Carvalho de Assis (2017-08-31). + * STM32 Timer: Add the set counter function for stm32 timers. From + Sergey Ustinov (2017-08-31). + * configs/Bambino: Add protected mode configuration to Bambino board. + From Alan Carvalho de Assis (2017-08-31). + * STM32L4 DAC: add option for routing DAC output to ADC. Actually + write something to the DAC DMA buffer. From Juha Niskanen + (2017-08-29). + * STM32L4 DAC: separate DMA buffer configuration for channels. From + Juha Niskanen (2017-08-29). + * STM32L4 DAC: Fix naming so that DAC1 and DAC2 always refer to + channels 1 and 2. User should not be bothered by details like how + many IP blocks there are. As no current STM32L4 has second DAC block + (channel 3), remove support for such hypothetical hardware. DMA + channels corrected. From Juha Niskanen (2017-09-01). + * configs/nucleo-l496zg: add DAC and missing TIM frequencies. From + Juha Niskanen (2017-09-01). + * Networking: net_timedwait() and net_lockedwait() no longer return + errors via errno but returned negated errno values like other + internal OS functions (2017-09-01). + * Networking: Fix net_lock returning ERROR when instead of real error + code on failure. From Jussi Kivilinna (2017-09-01). + * net/local: Fix server lc_waitsem overflow. From Jussi Kivilinna + (2017-09-01). + * drivers/bch: Add poll support. From Jussi Kivilinna (2017-09-01). + * STM32 F7: do not enable read-modify-write on DTCM. "AN 4667 - + STM32F7 Series system architecture and performance" recommends to + disable read-modify-write on DTCM: "If the DTCM-RAM is used as data + location and the variables used are byte or/and halfword types, since + there is no ECC management in this RAM on the STM32F7 Series, it is + recommended to disable the read-modify-write of the DTCM-RAM in the + DTCM interface (inthe DTCMCR register) to increase the performance." + From Jussi Kivilinna (2017-09-01). + * Networking: IGMP: Remove special support for interrupt level + processing (there is none) and fix some timer cancellation logic. In + many files, correct comments. There is no interrupt level processing + in the networking layer (2017-09-02). + * stm32_dac.c: fix compilation when DMA disabled for channel. From + Mateusz Szafoni (2017-09-02). + * Extend the RTC framework with an alarm read ioctl (RTC_RD_ALARM). + Through it consumer could get configuration settings about previously + scheduled hardware alarms (active status, hours, minutes, seconds). + From Boris Astardzhiev (2017-09-03). + * STM32 F7: Port Boris Astardzhiev's RTC change for STM32L4 to STM32F7 + (2017-09-03). + * STM32: Port Boris Astardzhiev's RTC change for STM32L4 to STM32 + (2017-09-03). + * Kinetis: Unverified implementation of the alarm read function. + Pretty simple because the Kinetis RTC is just a 1Hz counter + (2017-09-03). + * STM32 HRTIM: add burst mode configuration, rename some definitions. + From Mateusz Szafoni (2017-09-03). + * Update net_timedwait() and net_lockedwait() call sites to handle + negated errno in return value.

From Oleg Evseev + (2017-09-08). + * Update/fix last commit: On some STM32's, the CSR regiser is 18 vs. 16 + bits wide. Need to use 32-bit register accesses (2017-09-08). + * 6LoWPAN: I believe, based on RFC review, that with the last multicast + change, the NuttX 6LoWPAN is now compliant with RFC 6282 (2017-09-08). + * arch/arm/Kconfig: Add more classic ARM11 architecture selections + (2017-09-09). + * 6LoWPAN/Radio: Rename radio property sp_pktlen to sp_framelen. Add + 6LoWPAN utility to get the max frame length (not yet hooked in) + (2017-09-10). + * 6LoWPAN: Remove the option to disable fragmentation support. Two + reasons: (1) First fragementation is always required because IPv6 + requires an MTU of 1280 bytes. The is no application use case that can + work without fragmentation support. And (2) it greatly reduces the + complexity of the code (2017-09-10). + * net/sixlowpan: Remove CONFIG_NET_6LOWPAN_FRAMELEN.

So for that behavior you + could add a read-only routing table to the board-specific long that + contains a single entry, the default route: 0.0.0.0/0 (2017-09-28). + * fs/vfs: file_seek() is an internal OS interface and should not errors + via the errno (2017-09-28). + * fs/vfs: file_read() is an internal OS interface and should not errors + via the errno (2017-09-28). + * fs/vfs: file_write() and file_pwrite() are internal OS interfaces and + should not report errors via the errno (2017-09-28). + * STM32L4 FLASH, DFSDM: option bytes, JEXTSEL bits, ADC1 output to DFSDM + chips change + - STM32L4 FLASH: add function for modifying device option bytes + - STM32L4 DFSDM: add JEXTSEL bits, ADC1 output to DFSDM chips change + ST's documentation hints that ADC output can be routed to DFSDM on + some STM32L4X3 chips, but I got confirmation from tech support that + this is just a documentation error so remove this from Kconfig + From Juha Niskanen (2017-09-29). + * This commit adds support for routing tables in files in a file + system. This might be useful for customized, per-unit routing tables. + There are two issues with it however: + 1. Reading from file system on a per packet basis could be slow. I + think it probably should have a small, in-memory cache of most + frequently used routes for good problem. + 2. Currently the delroute logic is disabled due to a problem with + the design. NuttX does not currently support truncate(). + Therefore, it is not possible to delete entries from the routing + table file. + In this current implementation, that leaves the last entry intact at + the end of the file. An alternative design might include a tag on + each record to indicate if the record is valid or not. That would + work but would add complexity to the other routing table functions + (2017-09-29). + * net/route: Add support for an in-memory routing table cache in order + to improve performance when the routing table is retained in a file. + The cache holds the most recently used routing table entries and so can + eliminate some file access. Flush the in-memory cache when any entry is + deleted from the routing table. When a router matching an IP address is + found, add the routing table entry to the cache (2017-09-29). + * fs/vfs: null check for path on open and buf on write.

In + all recent STM32 chips reading either RTC_SSR or RTC_TR is supposed + to lock the values in the higher-order calendar shadow registers + until RTC_DR is read.

Changed all + references to sem_init in the OS to nxsem_init() (2017-10-03). + * sched/semaphore: Rename all internal private functions from sem_xyz + to nxsem_xyz. The sem_ prefix is (will be) reserved only for the + application semaphore interfaces (2017-10-03). + * libc/semaphore: Add nxsem_getvalue() which is identical to + sem_getvalue() except that it never modifies the errno variable. + Changed all references to sem_getvalue in the OS to nxsem_getvalue() + (2017-10-03). + * libc/semaphore and sched/semaphore: Add nxsem_getprotocol() and + nxsem_setprotocola which are identical to sem_getprotocol() and + set_setprotocol() except that they never modifies the errno variable. + Changed all references to sem_setprotocol in the OS to + nxsem_setprotocol(). sem_getprotocol() was not used in the OS + (2017-10-03). + * sched/semaphore: Add nxsem_destroy() which is identical to + sem_destroy() except that it never modifies the errno variable. Changed + all references to sem_destroy() in the OS to nxsem_destroy() (2017-10-03). + * sched/semaphore: Add nxsem_post() which is identical to sem_post() + except that it never modifies the errno variable. Changed all + references to sem_post in the OS to nxsem_post() (2017-10-03). + * sched/semaphore: Add the function nxsem_wait(). This is a new + internal OS interface. It is functionally equivalent to sem_wait() + except that (1) it is not a cancellation point, and (2) it does not set + the per-thread errno value on return. In all OS functions (not + libraries), change sem_wait() to nxsem_wait(). This will prevent the OS + from creating bogus cancellation points and from modifying the per-task + errno variable. This commit also backs out most of commit + b4747286b19d3b15193b2a5e8a0fe48fa0a8638c. That change was added because + sem_wait() would sometimes cause cancellation points inappropriately. + But with these recent changes, nxsem_wait() is used instead and it is + not a cancellation point (2017-10-04). + * sched/semaphore: sem_timedwait() is a cancellation point and, hence, + cannot be called from within the OS. Created nxsem_timedwait() that is + equivalent but does not modify the errno and does not cause + cancellation. All calls to sem_timedwait() change to calls to + nxsem_timedwait() in the OS (2017-10-05). + * sched/semaphore: sem_trywait() modifies the errno value and, hence, + should not be used within the OS. Use nxsem_trywait() instead + (2017-10-05). + * This change renames all internal, private NuttX signal-related + functions to use the prefix nxsig_ so that they cannot be confused with + application interfaces that begin, primarily, with sig_. This is + analogous to similar renaming that was done previously for semaphores + (2017-10-05). + * drivers/input/cypress_mbr3108: Add missing variable for nxsem_wait + return value.

The internal OS versions differ from the + standard application interfaces in that they do not create + cancellation points and they do not modify the application's errno + variable (2017-10-06). + * Adds new OS internal functions nxsig_sleep() and nxsig_usleep. These + differ from the standard sleep() and usleep() in that (1) they don't + cause cancellation points, and (2) don't set the errno variable (if + applicable). All calls to sleep() and usleep() changed to calls to + nxsig_sleep() and nxsig_usleep() (2017-10-06). + * drivers/serial/tcdrain: tcdrain() was recently added to the NuttX C + library. But there is a problem. The specification of tcdrain() + requires that it be a cancellation point. In order to do this, tcdrain + was moved from the C library into the OS and the addition cancellation + point hooks were added. In non-FLAT builds, access via system calls is + also now supported (2017-10-06). + * net/Kconfig: Remove improper use of comma in syntax (2017-10-06). + * mm/: Heap semaphore logic needs to use nxsem_* interfaces when + available, but the standard semaphores only when implementing a + user-space heap.

Since CAN driver API + pretends to be "file like" I expect data to be read from fd the same + order it is written. So I consider described behaviour to be a bug. + + I propose either to set TXFP bit in the CAN_MCR register (FIFO + transmit order) or to use only one mailbox (2017-10-19). + * The timer frequencies (BOARD_TIMx_FREQUENCY) are incorrectly defined + in configs/stm3240g-eval/include/board.h. Since the APB prescalers are + set to divide by 4 and 2 respectively, the frequencies should be + "2xAPBx" as said in the comment.  The correct frequencies are already + defined but as STM32_APBx_TIMx_CLKIN. From Mattias Edlund (2017-10-19). + * drivers/ioexpander: The IRQ subsystem now supports passing a void * + parameter to IRQ handlers. Use that method to support multiple pc9555 + devices, by passing a pointer to the device to the board defined irq + handler. Now the CONFIG_ for multiple PCA devices just allocates device + structures dynamically instead of statically when not enabled. + + The same interrupt handler is entered with the device structure + parameter in all situations, multiple or single PCA. One should still + be careful if multiple PCA devices share the same IRQ. From Sebastien + Lorquet (2017-10-19). + * libc/match: Use of exp() vs expf() in logf() caused function to be + slow. From Alan Carvalho de Assis (2017-10-19). + * drivrs/mtd/filemtd.c: add block device MTD interface. Block MTD + interface allows using block device directly as MTD instead of having to + use file-system in between. NOTE that this provides the opposite + capability of FTL which will let you use an MTD interface directly as a + block device. From Jussi Kivilinna (2017-10-19). + * There was a reference counting problem in the TPC logic of + net_clone(). net_clone() which is the common logic underlying dup() and + dup2() for sockets. When net_clone() calls net_start_monitor() and + net_start_monitor() returns a failure (because the underlying TCP + connection) then net_clone() must back out the reference count on the + structure. Problem noted by Pascal Speck and this implementation of the + solution is based on his suggestion (2017-10-19). + * There was a possible recursion that could eventually overflow the + stack. The error occurred when closing the socket with inet_close() + while a socket callback was still queued. When the socket callback was + executed by devif_conn_event(), this resulted in a call to + psock_send_eventhandler() with TCP_CLOSE flag set which then called + tcp_lost_connection(). tcp_shutdown_monitor() then called + tcp_callback() again, which again called psock_send_eventhandler(), and + so on....

The Local socket + implementation maintained file descriptors to interrupt with the pipes. + File descriptors have the bad property that they are valid only while + running on the thread within the task that created the local socket. + + As a policy, all internal OS implementations must use "detached" files + which are valid in any context and do not depend on the validity of a + file descriptor at any point in time. This commit converts the usage + of file descriptors to detached files throughout the local socket + implementation (2017-11-02). + * fs/userfs: There are some deadlock issues that make the UserFS + un-usable at the current time. Added to the TODO list; also feature is + now marked EXPERIMENTAL (2017-11-02). + * drivers/serial/serial.c: Optimize wait time in tcdram() for buffer + emptying. According to the specification, the close function must wait + until all data has been written before it closes the file (except + O_NONBLOCK is set). The maximum waiting time for this is not specified. + + To be able to edit the file list of the process, the close function + has to lock the file list semaphore. After that the close function of + the serial driver is called. + + Waiting for the complete transmission of all data is done in the + serial driver. This causes the semaphore to remain locked until all + data has been sent. However, no other thread of the process can edit + the file list for that time (open, close, dup2, etc.). This is not + optimal in a multithreaded environment. Therefore, we have to keep + the waiting time within the driver as short as possible.

The problem with the local sockets is that they do require + operations on the top level pseudo-file system inode tree. That tree + must be locked during certain traversals such as enumerate mountpoints + or enumerating directory entries. + + This conversion is unfortunate in the sense that Unix local domain + sockets are relatively lightweight. LocalHost UDP sockets are much + heavier weight since they rely on the full UDP stack. If anyone is + up for a complete redesign, then using some shared memory and a POSIX + message queue would be lightweight again. + + This commit also fixes several bugs that were not testable before the + inode tree deadlock.

Add support + for power pin to SDMMC driver. In SDMMC driver, don't do DMA if the entire + transfer will fit in the FIFO. In SDMMC driver, add logic to transfer data + when TXDR or RXDR interrupts occur. Also, add logic to set the RX + watermark to 2 when receiving short, non-DMA data transfers. In SDMMC + driver, fix an error which was clobbering the interrupt mask register + (xfrmask). Also, add a kludge for the missing DTO interrupt. From Gregory + Nutt (2017-12-20). + * arch/arm/src/lc823450: Add SP_DMB() into lc823450_testset.c. In + lc823450, ldrex and strex are not supported. So we implemented up_testset() + with H/W Mutex. However, there was a bug in memory access order. This + change ensures correct memory access order in up_testset() for lc823450. + From Masatoshi.Tateishi (2017-12-21). + * sched/semaphore/spinlock.c: Add memory barrier operations in + spin_unlock(). In ARM document regarding memory barriers, SP_DMB() must be + issued before changing a spinlock state to SP_UNLOCKED.

(64bit only). If SMP=n or SMP=y && SPINLOCK_IRQ=n, this + works in the same way as before. If SMP=y && SPINLOCK_IRQ=y, performance + will be improved. From Masayuki Ishikawa (2018-01-15). + * sched/clock/clock_systimer.c: Change the way that the 64-bit time is + sampled. Previously, we disabled interrupts before sampling the 64-bit + timer since the uint64_t access is not atomic on most CPUs. However, + disabling (local) interrupts does not work in the SMP case. In that case, + the timer interrupt will be running on only one of the CPUs; disabling + interrupts on a different CPU will provide no protection from timer + rollover. To work around this, logic was added that samples 64-bit timer + is sampled twice and if 32-bit rollover was detected between samples, then + loops until there is no rollover. From Gregory Nutt (2018-01-15). + * configs/nucleo-l432kc/src: Fix some bogus logic noted by Fanda.

From Evgeniy Bobkov (2018-01-16). + * Fixed nucleo-l432kc broken build when CONFIG_USERLED_LOWER defined From + Fanda (2018-01-16). + * Remove the BOARDIOC_TSCTEST_TEARDOWN boardctl() command. Remove all + implementations of board_tsc_teardown() (they were all stubs anyway except + for the simulation). From Gregory Nutt (2018-01-16). + * SMP: Introduce spin_lock_wo_note() and spin_unlock_wo_note(). These APIs + are used in sched_note.c to protect instrumentation data. The difference + between these APIs to exsiting spin_lock() and spin_unlock() is that they + do not perform instrumentation to avoid recursive call when + SCHED_INSTRUMENTATION_SPINLOCKS=y. From Masayuki Ishikawa (2018-01-17). + * configs: Eliminates the BOARDIOC_TSCTEST_SETUP command. Each board now + initializes the touchscreen controller as a normal part of its board + bring-up. board_tsc_setup() is gone; the touchscreen controller is now + treated like any other on-board device. + * configs: Since the touch screen initialization is now called from + one-time board-initialization logic, it no longer needs protection from + re-entry. From Gregory Nutt (2018-01-17). + * configs: CONFIG_MAX_TASKS must be a power of 2. From Gregory Nutt + (2018-01-17). + * configs: There should be either CONFIG_LIB_BOARDCTL=y or + CONFIG_BOARD_INITIALIZE=y (but not both) in the defconfig of every + standalone NxWM configuration to assure that all of the board resources are + initialized... especially the touchscreen since it is now a part of the + board driver initialization.

From + Masayuki Ishikawa (2018-01-18). + * drivers/input/ft5x06.c: Remove logic to disable polling when there there + is no client waiting for read data. That was a great idea to save CPU + cycles when there is nothing reading from the touchscrren but, + unfortunately, does not work with readers that open the driver in + non-blocking mode. So I think we just have to eat the CPUs even when there + is nothing waiting for touchscreen input.

From David Alessio (2018-01-22). + * net/: The existence of the network driver ioctl() method should depend on + CONFIG_NETDEV_IOCTL rather than CONFIG_NETDEV_PHY_IOCTL. The former + enables the method, the later enables a subset of possible driver IOCTLs. + This change should be basically a no-operation. The affected ioctl methods + only support those subset of driver IOCTLs selected by + CONFIG_NETDEV_PHY_IOCTL and the network logic will tolerate a nul ioctl + method. From Gregory Nutt (2018-01-22). + * net/tcp: Write buffering logic should not wait for a free buffer if the + socket was opened non-blocking.

Unlike the F1, these parts do not have a separate BKP address + region. The BKP registers are with the RTCC address regions. stm32_bkp.h + should only be used for STM32 F1. stm32_rtcc.h should be used to access BKP + registers on F2, F3, and F4.

After performing SPI I/O to a Mode 0 device, switching to a Mode 3 + device locked up the SPI interface. Only zeroes would be read. I traced + the reason for the lock-up to arm/arm/src/stm32f7/stm32_spi.c function + spi_setmode(). Changing the mode causes a spurious SPI clock transmission + that confuses the stm32f7 SPI input hardware. This problem is solved by + (1) changing the SPI mode with SPI (and perhaps DMA) disabled, and (2) + flushing the receive FIFO if the mode change results in garbage in the + FIFO. From Bob Feretich (2018-01-29). + * drivers/sensors: Add support to MAX44009 ambient light sensor From Juha + Niskanen (2018-01-29). + * tools/logparser: Add a tool which (when it matures) will help me to + convert git logs to ChangeLog format.

All usage of sched_setaffinity() within the OS is replaced with + nxsched_setaffinity(). From Gregory Nutt (2018-01-30). + * sched/sched: Internal functions sched_reprioritize() and + sched_setpriority() no longer modify the errno value.

All usage of sched_setparam() within the OS is replaced with + nxsched_setparam(). From Gregory Nutt (2018-01-30). + * sched/sched: Add new internal OS function nxsched_getparam() that is + identical to sched_getparam() except that it does not modify the errno + value (actually, the previous value erroneously neglected to set the errno + value to begin with, but this fixes both issues). All usage of + sched_getparam() within the OS is replaced with nxsched_getparam(). From + Gregory Nutt (2018-01-30). + * sched/: Fix several inappropriate accesses to get_errno() that were + missed in previous changes (some going back to nuttx-.23). Add new + nxsched_setscheduler() and nxsched_getaffinity() which are equivalent to + their counterparts without the nx on front. These versions do not modify + the errno value. Changed all calls within the OS to use these newer + versions of the functions. From Gregory Nutt (2018-01-30). + * binfmt/, configs/, grahics/, libc/, mm/, net/, sched/: OS references to + the errno variable should always use the set_errno(), get_errno() macros. + From Gregory Nutt (2018-01-30). + * arch/arm/src/stm32 and stm32f7: Architecture-specific code is not + permitted to modify the errno variable. drivers/ and libc/: OS references + to the errno variable should always use the set_errno(), get_errno() + macros. From Gregory Nutt (2018-01-30). + * SMP: Introduce a new global IRQ clearing logic and tasklist protection. + The previous implementation of clearing global IRQ in sched_addreadytorun() + and sched_removereadytorun() was done too early. As a result, nxsem_post() + would have a chance to enter the critical section even nxsem_wait() is + still not in blocked state. This patch moves clearing global IRQ controls + from sched_addreadytorun() and sched_removereadytorun() to + sched_resumescheduler() to ensure that nxsem_post() can enter the critical + section correctly. For this change, sched_resumescheduler.c is always + necessary for SMP configuration. In addition, by this change, task_exit() + had to be modified so that it calls sched_resumescheduler() because it + calls sched_removescheduler() inside the function, otherwise it will cause + a deadlock. However, I encountered another DEBUGASSERT() in + sched_cpu_select() during HTTP streaming aging test on lc823450-xgevk. + Actually sched_cpu_select() accesses the g_assignedtasks which might be + changed by another CPU. Similarly, other tasklists might be modified + simultaneously if both CPUs are executing scheduling logic. To avoid this, + I introduced tasklist protetion APIs. With these changes, SMP kernel + stability has been much improved. From Masayuki Ishikawa (2018-01-31). + * arch/arm/src/samdl: Added I2S register definitions.

In the + previous implementation, this_task() was defined in sched.h by using just a + macro current_task(this_cpu()). However, I found that this is not atomic + and actually sometimes switching CPU happened in executing the macro when + we tested audio steaming plus executing commands via telnet.

From Masayuki Ishikawa (2018-02-04). + * configs/stm32f429i-disco: Separate SPI4 from MTD init. I was trying to + attach a non-MTD peripheral to an STM32F429I Discovery Board's SPI4 port + and was hitting compilation problems, since CONFIG_MTD and thus 'struct + mtd_geometry_s' was not defined. This patch separates SPI4 initialization + logic from MTD initialization logic. From Michael Jung (2018-02-05). + * sched/sched: Implements a global scheduler lock capability as part of + SMP support. This allows the scheduler to be locked with no knowledge or + access to the TCB of the currently running task. This is necessary because + accessing the TCB of the currently running task is, itself, a non-atomic + operation. This global scheduler lock capability was add just to support + that atomic access to the TCB. From Gregory Nutt (2018-02-05). + * sched/sched: Extend the last global lock change to work with the + lc823450-xgevk which does not support the atomic fetch add but does support + disabling interprocessor interrupts. Disabling interprocessor interrupts + will also guarantee that the TCB address calculation is atomic. From + Gregory Nutt (2018-02-05). + * sched/irq: Fix a infinite recursion problem that a recent change + introduced into the i.MX6 SMP implementation. From Gregory Nutt + (2018-02-06). + * arch/arm/src/armv7-a: Found some additional places were the new + this_task() function cannot be called in the i.MX6 SMP configuration.

It does not yet work, sadly. From Gregory Nutt + (2018-02-06). + * sched/task: It is not appropriate for logic in task_exit() to call the + new version of this_task(). sched/irq: Remove redundant fetch of CPU + index; configs/sabre-6quad: update README. From Gregory Nutt (2018-02-06). + * arch/arm/src/lpc17xx: Disable LPC17 FDR when not used.

This change + prevents from a deadlock in up_schedulesigaction.c where inter-CPU signal + handling is actually implemented. arch/arm/src/armv7-m: Fix signal + handling for SMP. In previous implementation, signal handling for SMP was + incorrect. Thus, for example, if an inter-CPU signal happened an incorrect + tcb was signaled and caused ASSERT(). This change fixes the issues and + works for both inter-CPU signal handling and signal handling on the same + CPU. From Masayuki Ishikawa (2018-02-14). + * arch/arm/src/armv7-a: Port the SMP change by Masayuki Ishikawa to the + ARMv7-A family.

This change will improve performance for SMP systems but + nothing changes for non-SMP systems. In SMP mode, rtrtcb is not always at + the g_readytorun.head. This change removes DEBUGASSERT() to avoid this + condition. From Masayuki Ishikawa (2018-02-15). + * drivers/lcd: lcd_framebuffer.c does not need to include board-specific + board.h.

From Gregory Nutt (2018-03-19). + * sched/sched: Fix a deadlock in SMP mode. Two months ago, I introduced + sched_tasklist_lock() and sched_tasklist_unlock() to protect tasklists in + SMP mode. This change works well for HTTP audio streaming aging test with + lc823450-xgevk. However, I found a deadlock in the scheduler when I tried + similar aging tests with DVFS autonomous mode where CPU clock speed + changed based on cpu load. In this case, call sequences were as follows. + To avoid this deadlock, I added sched_tasklist_unlock() when calling + up_cpu_pause() and sched_addreadytorun(). Also, added + sched_tasklist_lock() after the call. Also added critical sections to + lib_filesem.c, mm_sem.c, and net_lock.c for SMP for SMP.

From Juha + Niskanen (2018-03-22). + * i2c/i2c_master.h: Change incorrect comment about I2C_TRANSFER return + value to indicate that the method returns zero on success rather than the + number of bytes transferred. From Juha Niskanen (2018-03-22). + * configs/: Remove configurations using canutils/libuavcan and + examples/uavcan. libuavcan has not built for a year or so. The basic + problem is that as NuttX advances, the old frozen version of libuavcan has + become absolute because it violates the portable POSIX OS interface. No + one is maintaining the port so there is no alternative but to remove it. + From Gregory Nutt (2018-03-23). + * STM32, STM32L4: Add one bit read and write to 1-wire interface.

From Janne Rosberg (2018-03-26). + * Per Matias Edlund: I recently used the tcflush function and found that it + failed with ENOTTY. The reason is that the TCFLSH case in the function + uart_ioctl in the file drivers/serial/serial.c does not update the ret + value." On success, the TCFLSH IOCTL logic needs to explicitly set the + return value (ret) to zero. From Gregory Nutt (2018-03-26). + * netdb: Fix boundary conditions in dns_recv_response(). Fix typos in + include/nuttx/net/dns.h From Masayuki Ishikawa (2018-03-27). + * configs/nrf52-pca10040: Add support for the NRF52-PCA10040 board + including LEDs and buttons From Janne Rosberg (2018-03-27). + * arch/arm/src/stm32: In case of PHY failure, usually because of the lack + of 25/50 MHz REFCLK input, the Ethernet block would lock up in a while + loop waiting for readiness, which will never happened.

From Sebastien Lorquet (2018-03-27). + * mac802154: Adds basic support for RX-ENABLE.request primitive From + Anthony Merlino (2018-03-28). + * mac802154: Adds ackreq flag to TX descriptor for use by radio driver. The + radio layer is responsible for a full "transaction". Because of + differences in radio capabilities, the radio must be responsible for the + handling of acks and retransmissions.

From Dmitry Sharihin (2018-04-19). + * drivers/net: Add TAP (network bridge) mode to tun.c. In previous + implementation, TAP mode did not handle a packet correctly. Also, the + driver did not set the link layer type and could not assign the interface + name. This change fixes such issues and supports TAP mode correctly. From + Masayuki Ishikawa (2018-04-20). + * arch/arm/src/nrf52: Add watchdog timer drivers.

The NuttX + convention is that all internal functions that return errors as an 'int' + must return a negated errno value on failure and a non-negative value on + success. Most were right but eight of them had cloned logic that returns + 1 on success and zero on failure... both of which are interpreted as + success by the caller since they are non-negative. From Gregory Nutt + (2018-04-21). + * Makefile: Add support for nconfig frontend for 'make nconfig' From Michał + Łyszczek (2018-04-22). + * arch/arm/sc/lpc17xx: Freeing endpoints should be set the same allocations + as when endpoint was allocated.

Unlike most other unlink + implementations in NuttX drivers, this one does not allow any I2C + operations after unlink, making it possible to deallocate the I2C bus. + From Juha Niskanen (2018-04-24). + * configs/ stm32f746g-disco. Add clang support to stm32f746g-disco board + From Goran Mekić (2018-04-24). + * net/udp: Fix several issues using connected UDP sockets: sendto() should + not accept an address. Normally send() should be used with connect UDP + sockets instead. recvfrom() is no longer necessary. recvfrom() and + poll() should not reset to accept any addresses but should, instead, only + accept inputs and events from the connected remote peer.

Adds support for the Kinetis Freedom-K28F board. + From Gregory Nutt (2018-05-02). + * fs/nfs/rpc_clnt.c: Commit 091e3f7 broke the NFS client. sendto() can + (correctly) no longer be used with a connected UDP socket. In that case, + send() must be used instead. From Michael Jung (2018-05-02). + * drivers/rgbled: Adds support for multichannel PWM (multiple PWM channels + on a single timer) From Anthony Merlino (2018-05-02). + * drivers/sensors: Adds support for INA3221 power sensor.

From Gregory Nutt (2018-05-05). + * arch/arm/src/lpc17xx: Add support for ARMv7-M run time stack checking on + NXP LPC17xx MCUs based on CONFIG_ARMV7M_STACKCHECK. Basically copied from + stm32. From Michael Jung (2018-05-06). + * arch/arm/src: All ARM and MIPS architectures now support + CONFIG_ARCH_IDLE_CUSTOM From Gregory Nutt (2018-05-07). + * drivers/mtd/mtd_config.c: mtdconfig_register() returned OK instead of + -ENOMEM on failed malloc From Michał Łyszczek (2018-05-08). + * configs/teensy-3.x/usbnsh: Remove CONFIG_USBDEV_DUALSPEED from + configuration. Hardware supports only FS. From Gregory Nutt (2018-05-09). + * libc/unistd: Initial, minimal implementation of sysconf(). Only + sufficient to support the functionality of less standard + getdtabilesize(). From Michael Jung (2018-05-10). + * Documentation/NuttShell.html: Document the mkfatfs the -r option which + can be used to specify the number of entries in the FAT12/FAT16 root + directory. From Gregory Nutt (2018-05-11). + * LibTargets.mk, tools/Config.mk: Drop executable bit on installed + libraries. The rules to install libraries under lib/ were modified to use + mode 0644 instead of the default 0755. From Andrey Zabolotnyi (2018-05-12). + * arch/arm/src/stm32: Add internal pull-up option for SDIO pins (also picks + up an unrelated change to a README.txt file) From Alan Carvalho de Assis + (2018-05-12). + * arch/arm/src/kinetis + SDHC configs: Make Kinetis SDHC pullups work the + same as the STM32 SDIO pullups From Gregory Nutt (2018-05-12). + * net/udp: Resolve race condition in connection-less UDP sockets with + read-ahead buffering. In connection-mode UDP sockets, a remote address is + retained in the UDP connection structure. This determines both there + send() will send the packets and which packets recv() will accept. This + same mechanism is used for connection-less UDP sendto: A temporary remote + address is written into the connection structure to support the sendto() + operation. That address persists until the next recvfrom() when it is + reset to accept any address. When UDP read-ahead buffering is enabled, + however, that means that the old, invalid remote address can be left in + the connection structure for some time. This can cause read-ahead buffer + to fail, dropping UDP packets. Shortening the time between when he remote + address is reset (i.e., immediately after the sendto() completes) is not a + solution, that does not eliminate the race condition; in only makes it + smaller. With this change, a flag was added to the connection structure + to indicate if the UDP socket is in connection mode or if it is + connection-less. This change effects only UDP receive operations: The + remote address in the UDP connection is always ignored if the UDP socket + is not in connection-mode. No for connection-mode sockets, that remote + address behaves as before. But for connection-less sockets, it is only + used by sendto(). From Gregory Nutt (2018-05-13). + * include/sys: Add resource.h From Gregory Nutt (2018-05-13). + * rgbled: Fixes led issues caused by uninitialized memory with + CONFIG_RGBLED_MULTICHAN. The uninitialized pwm_info_s struct caused a + rogue channel to be started causing errors in the pwm driver From Anthony + Merlino (2018-05-14). + * arch/arm/src/imxrt/chip: Add pin multiplexing header files. From Gregory + Nutt (2018-05-14). + * configs/nucleo-l452re: Add buttons example From Juha Niskanen + (2018-05-15). + * arch/arm/src/imxrt/imxrt_serial.c: Fix some interrupt instabilities; must + be in a critical section when modifying serial interrupts. + configs/imxrt1050-evk/nsh/defconfig: Use the BASEPRI register to + enable/disable interrupts; enable the PROCFS file system. From Gregory + Nutt (2018-05-15). + * arch/arm/src/imxrt: Add missing support for the Cortex-M7 caches; + configs/imxrt1050-evk: Enable I- and D-Caches in the nsh configuration. + Calibrate the delay loop. Add support for the on-board LED. From Gregory + Nutt (2018-05-15). + * arch/arm/src/imxrt: Corrects some IOMUX controls. From Jake Choy + (2018-05-15). + * net/sixlowpan: Preserve big-endian (network order) when uncompressing + address. From Anthony Merlino (2018-05-15). + * arch/arm/src/imxrt/chip: Add DMA channel assignments. From Gregory Nutt + (2018-05-15). + * arch/arm/src/stm32f7: Add support for the second SDMMC device. The + second SDMMC device was already supported but the clock was never + enabled. This fixes that. From William Douglas (2018-05-15). + * arch/arm/src/imxrt: Add eDMA support (unverified). From Gregory Nutt + (2018-05-16). + * net/sixlowpan: TCP send should have PSH and ACK flags set when sending. + This matches the standard network (Ethernet) TCP send logic. From Anthony + Merlino (2018-05-17). + * net/udp: Recent changes to UDP in order to correct problems with UDP + connection mode introduced a new bug: The 'to' address passed to sendto() + must now be NULL in connection mode. But there are errors because there + was one place where the 'to' address was still being used. This commit + adds logic to first check for UDP connection mode. If the UDP socket is + connected, then the NULL 'to' address is ignored and saved connection + address is used instead. From Gregory Nutt (2018-05-17). + * arch/arm/src/stm32: Added Vbat measurement to adc driver for STM32F20xx + and STM32F4xxx. As with the MCU temperature and VREFINT measurement, this + change requires user to enable the corresponding channel first. For Vbat + channel the ioctl cmd is IO_ENABLE_DISABLE_VBAT_CH, and its arg should be + a pointer to bool which must be true to enable and false to disable the + Vbat channel. Moreover, since Vbat input contains a built-in voltage + divider, it is highly suggested to disable Vbat input channel after + measurement is done in order to prevent battery drain through the + divider. From Dmitriy Linikov (2018-05-18). + * configs/stm32l1discovery: Add support for the STM32L152RCT6 version. + From Gregory Nutt (2018-05-18). + * configs/stm32f4discovery/audio: Add board configuration for CS43L22 audio + example. From Alan Carvalho de Assis (2018-05-19). + * drivers/lcd and configs/olimex-lpc1766stk: Remove support for the + Nokia6100 LCD. That LCD uses a 9-bit SPI interface (the 9th bit being the + command/data bit that is normally a discrete). That communication was + never successfully integrated. I now believe that it would would require + some special support from the low-level, MCU SPI driver to manage that 9th + bit. The deleted code is still available in the Obsoleted repository in + the nuttx/drivers/lcd, nuttx/configs/olimex-lpc1766stk, and Patches + directories. From Gregory Nutt (2018-05-19). + * arch/arm/src/lpc17xx/lpc17_usbdev.c: Fix loss of RX initiatives. USB + bulk endpoints are double buffered on LPC17xx MCUs. This means that up to + two packets might be received on an OUT endpoint that can not be handled + immediately if the receive request queue is empty. Thus, rxpending must + be a counter not a boolean flag. From Michael Jung (2018-05-20). + * configs/imxrt1050-evk/src: Add support for on-board NOR FLASH boot. From + Ivan Ucherdzhiev (2018-05-21). + * fs/fat: In fs_stat(), when stat'ing the root directory, avoid calculating + the address of the root directory entry. The calculation is bogus (but + not harmful) because the root directory does not have a directory entry. + Noted by Boris Astardzhiev. From Gregory Nutt (2018-05-23). + * fs/fat: Avoid calculating the bogus directory entry address for the FAT + root directory (since it has no directory entry). This change should have + no effect, other than making the logic clearer. From Boris Astardzhiev + (2018-05-24). + * configs/indium-f7: Removes support for the Indium-F7 board. This was + done for two reasons: (1) The board support was just clone of the + Nucleo-144 board support with naming changes. There has been no support + and no further development for the board support. (2) There does not seem + to be any available Indium-F7 board available to the public anywhere on + the internet. There is not even a reference to the board on the + rafresearch.com web stie. Gotta go. Its in the way. From Gregory Nutt + (2018-05-24). + * arch/arm/src/imxrt: Add Ethernet driver. From Jake Choy (2018-05-25). + * arch/arm/src/imxrt: Add cache operations to permit the Ethernet driver to + work with the D-Cache enabled, at least in write-through mode. Add + support for PHY interrupts and PHY IOCTLs. + * configs/imxrt1050-evk/netnsh/defconfig: Disable LED support because pins + conflict with PHY. Enable device statistics. Enable NSH ifup and ifdown + commmands. Add an NSH configuration for testing Ethernet. From Gregory + Nutt (2018-05-25). + * configs/xmc4500-relax: Add board support for SPI From Alan Carvalho de + Assis (2018-05-26). + * configs/olimex-stm32-p407: Add a zmodem test configuration. From Gregory + Nutt (2018-05-26). + * drivers/serial: Add a timeout to uart_tcdrain(). Even if tcflush() is + used to discard buffered data, the close() can still hang if (a) hardware + flow control is enabled, (b) CTS == 1, and (c) there is data stuck in the + hardware Tx FIFO. tcflush() does not currently clear the MCU serial + drivers' hardware Tx FIFOs. This is a workaround for that. From Gregory + Nutt (2018-05-27). + * Build system: Remove fixed lib/ subdirectory and its content. Replace + with new directory called staging/ that is created dynamically when + building and removed when 'make clean' is done. This both improves the + name and eliminates a garbage directory from the repository. From Gregory + Nutt (2018-05-29). + * Build system: Move all build-related files (except the top-level + Makefile) into the tools/ sub-directory. This really cleans up the + top-level directory. From Gregory Nutt (2018-05-29). + * libs/: This commit moves all of the libraries under a common directory + called libs/ (libc, libnx, and libxx). This most certainly break libcxx + for now. From Gregory Nutt (2018-05-29). + * libs/libdsp: Adds DSP support library. From Mateusz Szafoni (2018-05-30). + * arch/arm/src/kinetis: In kinetis_lowputc.c, fix esBRFA calculation + effecting baudrate.

From Gregory Nutt (2018-06-06). + * Based on a change recommended by Mark Shulte: + Signal handlers maybe run with interrupts enabled or disabled, + depending on how the task the received the signal was blocked. (i.e.: + If sem_wait() is called, then we disable interrupts, then block the + currently running task). This could be dangerous, because user code + would be running with interrupts disabled. + This change forces interrupts to be enabled in up_sigdeliver() before + executing the signal handler calling up_irq_enable() explicitly. + This is safe because, when we return to normal execution, interrupts + will be restored to their previous state when the signal handler + returns.

From Gregory Nutt (2018-06-21). + * net/udp: When sending a broadcast (or multicast) packet do not + attempt to look up the device by the destination IP address. Rather, + use the locally bound address for these cases to select the correct + network device. From Gregory Nutt (2018-06-22). + * net/: There are many different checks for IPv6 multicast addresses. + Most of the checks are different. RFC 3513 clearly specifies how to + detect an IPv6 multicast address: they should begin with 0xffxx. I + did not change some of the checks in ipv6_input.c, however. In that + file, the comments indicate that the code should only pick of certain + multicast address that begin withi 0xff02. From Gregory Nutt + (2018-06-23). + * net/: Fix a sixlowpan typo bug recently introduced; Rename + g_ipv6_allzeroaddre with the more meaning g_ipv6_unspecaddr since the + all-zero address is the IPv6 unspecified address (sometime + IN6_ADDR_ANY). Replace more inline tests for IPv6 multicast with + common net_is_addr_mcast() macro. From Gregory Nutt (2018-06-23). + * net/: Rename CONFIG_TCP_REASSEMBLY to CONFIG_IPv4_REASSEMBLY. Add + some fixes to get a clean compile with CONFIG_IPv4_REASSEMBLY + enabled. There are several problems with the current + implementation: It is untested (and depends on + CONFIG_EXPERMIMENTAL). It uses some Ethernet specific definitions + (and depends on CONFIG_NET_ETHERNET). There is only a single + reassembly buffer. The last two issues prevent use of this feature + in any context where IPv4 packets may be reassembled for multiple + network devices concurrently). From Gregory Nutt (2018-06-24). + * net/tcp: Re-think CONFIG_NET_TCP_RWND_CONTROL TCP windowing + controls. From Gregory Nutt (2018-06-24). + * net/udp: Fix a hole in the address lookup logic.

Add implementation of + if_nametoindex() and if indextoname(). Raw AF_PACKET sockets now + depend on CONFIG_NETDEV_IFINDEX. Add syscall support for + if_nametoindex() and if_indextoname(). + Includes an algorithm to prevent an interface index from being reused + until all network interfaces have by assigned once.

In case of + CONFIG_SMP=y, g_cpu0_instack_base and g_cpu1_instack_base are not + allocated just after g_instack_alloc but these values show the + addresses for interrupt stack of each CPU. So to set the stack + pointer based on these variables, temporal register has to be used. + From Masayuki Ishikawa (2018-06-27). + * arch/arm/src/imxrt: Add support for the i.MXRT RTC. This initial + commit is code complete (with limited features and options) but untested. + The HPRTC is functional. However, if the LPSRTC is enabled, then + there is a hang during LPSRTC initialization. It appears that there + is some problem in providing clocking and initializing the LPSRTC + domain. From Gregory Nutt (2018-06-27). + * tools/testbuild.sh: Add option to specify location of nuttx + directory. From Gregory Nutt (2018-06-27). + * stm32f7: I2C reset Configure I2C pins as GPIO output.

From + Masayuki Ishikawa (2018-07-03). + * drivers/usbhost/usbhost_max3421e.c: Add support for the Maxim M3421E + USB host driver. From Gregory Nutt (2018-07-03). + * net/udp: Restore some legacy behavior that was lost with the + implementation of CONFIG_NET_UDP_BINDTODEVICE: If no device has a + local address when the broadcast packet is sent and the UDP socket is + not bound to a device, there select some arbitrary device. This is + certainly lunacy in the case where there are multiple network devices + registered because the wrong device will probably be returned. It + works find, however, for the legacy case where only a single network + device is registered. From Gregory Nutt (2018-07-04). + * arch/arm/src/samv7: Add ability for CAN BUS_OFF autorecovery + according ISO11898-1:2015. With this change we added an ioctl for + triggering the autorecovery sequence for BUS_OFF to the CAN-driver + and the SAMV7 low-level driver. According the datasheet: If the + device goes Bus_Off, it will set MCAN_CCCR.INIT of its own accord, + stopping all bus activities. Once MCAN_CCCR.INIT has been cleared by + the processor (application), the device will then wait for 129 + occurrences of Bus Idle (129 * 11 consecutive recessive bits) before + resuming normal operation. At the end of the Bus_Off recovery + sequence, the Error Management Counters will be reset. During the + waiting time after the resetting of MCAN_CCCR.INIT, each time a + sequence of 11 recessive bits has been monitored, a Bit0 Error code + is written to MCAN_PSR.LEC, enabling the processor to readily check + up whether the CAN bus is stuck at dominant or continuously disturbed + and to monitor the Bus_Off recovery sequence. MCAN_ECR.REC is used to + count these sequences. From Frank Benkert (2018-07-04). + * This commit attempts remove some long standard confusion in naming + and some actual problems that result from the naming confusion. The + basic problem is the standard MTU does not include the size of the + Ethernet header. For clarity, I changed the naming of most things + called MTU to PKTSIZE. For example, CONFIG_NET_ETH_MTU is now + CONFIG_NET_ETH_PKTSIZE. + This makes the user interface a little hostile. People thing of an + MTU of 1500 bytes, but the corresponding packet is really 1514 bytes + (including the 14 byte Ethernet header). A more friendly solution + would configure the MTU (as before), but then derive the packet + buffer size by adding the MAC header length. Instead, we define the + packet buffer size then derive the MTU. + The MTU is not common currency in networking. On the wire, the only + real issue is the MSS which is derived from MTU by subtracting the IP + header and TCP header sizes (for the case of TCP). Now it is derived + for the PKTSIZE by subtracting the IP header, the TCP header, and the + MAC header sizes. So we should be all good and without the recurring + 14 byte error in MTU's and MSS's. From Gregory Nutt (2018-07-04). + * arch/arm/src/stm32f7/stm32_sdmmc.c: Add SDIO card support. From + Ramtin Amin (2018-07-05). + * net/tcp: Set the default TCP MSS to the value required by RFC 879 + and never change it under any circumstance unless the remote host + requests a larger MSS via an option the TCP header. From Gregory + Nutt (2018-07-05). + * configs/viewtool-stm32f107: Add a TCP performance test using + apps/examples/tcpblaster. From Gregory Nutt (2018-07-05). + * net/tcp: Fix a deadlock condition that can occur when (1) all + network logic runs on a single work queue, (1) TCP write buffering is + enabled, and (2) we run out of IOBs. In this case, the TCP write + buffering logic was blocking on iob_alloc() with the network locked. + Since the network was locked, the device driver polls that would + provide take the write buffer data and release the IOBs could not + execute. This fixes the problem by unlocking the network lock while + waiting for the IOBs.

Because of this erratum, the priority boosting + does not take place immediately, allowing the instruction after the + MSR to be interrupted by an exception of lower priority than the new + boosted priority. This effect is only limited to the next + instruction. Subsequent instructions are guaranteed to see the new + boosted priority. + This was raised in Bitbucket issue 113 from Vadzim Dambrouski. From + Gregory Nutt (2018-08-02). + * net/tcp: Remove g_netstats.tcp.syndrop++ from tcp_data_event() From + Masayuki Ishikawa (2018-08-03). + * include/nuttx/i2c/i2c_master.h: Add a definition to distinguish a + new START of messages from a repeated start. No lower-half I2C + drivers actually implement this new flag bit, however. + drivers/i2c/i2c_writeread.c: Use new repeated START definition where + appropriate. Rename I2C_M_NORESTART to I2C_M_NOSTART since it may be + used in other contexts than a repeated start. Add comments to + clarify setup for repeated start. From Gregory Nutt (2018-08-03). + * configs/nucleo-l432kc: Fix stm32_userleds. After change LD2 to LD3 + in board.h stm32_userleds.c was broken. From Daniel P. Carvalho + (2018-08-03). + * arch/arm/src/stm32f7: This commit ports the stm32f20xxf40xx_flash.c + driver to the STM32F7 platform and fixes some relevant problems in + the header files. From Evgeniy Bobkov (2018-08-03). + * net/netlink: This commit brings in a fragmentary, experimental + implementation of NETLINK sockets. There is not too much to that + socket support on this initial commit, just the netlink socket + framework. However, I decided to bring it into master because there + is a enough that I would not want to lose what is in place. And + since it is dependent on CONFIG_EXPERIMENTAL, its presence on master + should be innocuous. From Gregory Nutt (2018-08-03). + * configs/metro-m4: Add an option to build the Metro M4 image to run + out of SRAM. This ought to be a safer and quicker way to do the + initial bring-up (having bricked the first Metro M4 due to a bad + FLASH image). From Gregory Nutt (2018-08-03). + * Revise the Cortex-M7 workaround: That change had the subtle + side-effect of unconditionally enabling interrupts in the primask. + That may be what we want in most cases, but certainly not all. This + does increase the size of the inline function by about 48-bits per + instantiation. From Gregory Nutt (2018-08-04). + * configs/olimex-stm32-p407: Add kernel ELF (kelf) configuration. + From Gregory Nutt (2018-08-04). + * binfmt/ and sched/group: Re-architect the way that loadable ELF or + NXFLAT modules are unloaded. Memory resources must be recovered when + the task loaded into memory exits. The original implementation used + the death-of-child SIGCHLD signal to perform the unload. There are + several problems with this: It is overly complex, it requires that + the parent task stay resident while the loaded task runs, and it has + fatal logic flaws in the protected and kernel model builds because + the user signal handler attempts to run in the kernel address space. + This commit corrects with using a mindlessly simply BINFMT callback + when the task exits. From Gregory Nutt (2018-08-05). + * Kconfig files: Fix several errors noted by Alex Denisov in Bitbucket + issue 115. From Gregory Nutt (2018-08-05). + * configs/olimex-stm32-p407/kmodule: Add a configuration that can be + used for testing installation of kernel modules in the protected + build. From Gregory Nutt (2018-08-05). + * sched/group: Fix a deadlock when loading an ELF From Masayuki + Ishikawa (2018-08-06). + * arch/arm/src/lc823450: Change C-Buffer under-level control. The + under-level setting was changed from 1KB to 55KB. In previous + implementation, the setting can ben changed by the tx threshold but + it is fixed at startup. Also, check write size and adjust alignment + if needed. + configs/lc823450-xgevk: Change IOB related params for RNDIS. Since + TCP flow control scheme was changed, HTTP audio streaming has not + been working. These IOB params are not optimized but HTTP audio + streaming now works. From Masayuki Ishikawa (2018-08-06). + * arch/arm/src/stm32l4/chip/stm32l4x3xx_pinmap.h: Recent commit removed + some of the pin definitions for STM32L451xx, and probably some other + chips of the STM32L4x3 subfamily, breaking our builds. Some chips of + the subfamily don't have these peripherals, but some do, so that is + not a valid reason to remove them. From Juha Niskanen (2018-08-06). + * stm32f103-minimum: Add blackpill LED support From Russ Webber + (2018-08-07). + * Build System: This change extends support for the two-pass build. + Its primary purpose is to incorporate source logic generated by + applications into the kernel phase of the build. + In the two pass build, the application logic is built during the + first phase, pass 1. In that phase, the application may generate and + install source files in the pass1/directory. The operating system is + built during phase 2 of the build. At that time, those source files + in the pass1/ directory will be built and incorporated into the + kernel address space. + The primary purpose of the pass1/ directory is to such + application-generated kernel symbol tables. For an example of the + use of this feature, look at apps/examples/module/drivers/Makefile. + Kernel symbol tables are needed to support kernel modules. Of + course, addition board-specific logic in, say, configs//src + would have to be included to make use of the application-installed + symbol tables. From Gregory Nutt (2018-08-07). + * configs/olimex-stm32_p407: Add logic to support initialization of + the kernel module symbol table installed in the pass1/ directory + during the application phase of the build. The kmodule configuration + appears to be fully functional. From Gregory Nutt (2018-08-07). + * configs/nucleo-l432kc/include/nucleo-l432kc.h: Fix TIMx clock + configuration. Also removes definitions related to timers not + available in the STM32L432KC. From Daniel Pereira Carvalho + (2018-08-07). + * arch/arm/src/stm32l4: Fix ADC and COMP breakage caused by + CONFIG_STM32L4_STM32L4X2 separation in 9223123c From Juha Niskanen + (2018-08-08). + * configs/nucleo-l452re: Fix TIMx clock configuration. This is cloned + from 391f3715 for nucleo-l432kc. Also fixes DAC build failure. From + Juha Niskanen (2018-08-08). + * arch/arm/src/stm32, stm32f7, stm32l4, and related defconfig files: + The STM32 RTC driver was being selected by the global CONFIG_RTC + option. That is in correct. For example, if you want to disabled + the STM32 RTC and use an external RTC you cannot because the external + RTC also depends on the global CONFIG_RTC. The solution is to add a + new CONFIG_STM32xx_RTC configuration option the permits to you select + or deselect the STM32 RTC but still be able to selecte the external + RTC. From Gregory Nutt (2018-08-08). + * configs/stm32f4discovery/scripts/ld.script: Missing + EXTERN(_vectors) From Gregory Nutt (2018-08-08). + * arch/arm/src/stm32l4: Avoid using redundant + CONFIG_STM32L4_STM32L4X2. This is almost always same as + CONFIG_STM32L4_STM32L4X3. Avoid duplication to reduce macro clutter. + This patch limits CONFIG_STM32L4_STM32L4X2 usage to dependency + tracking and pinmap. Also enable ADC for CONFIG_STM32L4_STM32L4X5 + (untested, but same RM). From Juha Niskanen (2018-08-09). + * arch/arm/src/stm32l4/chip: Merged stm32l4x2xx and stm32l4x3xx pinmap + files. Removed references to stm32l4x2xx_pinmap.h From Daniel P. + Carvalho (2018-08-09). + * arch/arm/src/kinetis: PIT add Liftime and Chaining + arch/arm/src/kinetis: flexcan fix duplicate line and ordering + arch/arm/src/kinetis: kinetis_lowput.c LPUART data format with + parity fix.

From Dmitriy + Linikov (2018-08-14). + * net/: Remove all references to CONFIG_NET_USER_DEVFMT. That feature + is now unconditionally enabled. This was done because (1) the + feature does not require very much additional memory, and (2) it + causes confusion in the configuration due to the additional + complexity. Any network drivers that fail to zero the device + structure interface name field (d_ifname) because calling + netdev_register() will, however, get a nasty surprise. From Gregory + Nutt (2018-08-14). + * net/: Change order of logic: Select the user-defined interface name + format BEFORE determining the minor device number. Otherwise, the + default interface name will be used. From Gregory Nutt (2018-08-14). + * tools/Config.mk: Add function CATFILE definition. Currently only + used in apps/builtin/Makefile. From Gregory Nutt (2018-08-15). + * tools/Config.mk: Move the RWILDCARD function definition from + apps/builtin/Makefile to nuttx/tools/Config.mk. It may have a + broader usage than it does now.

From Gregory Nutt (2018-08-17). + * fs/procfs/: Add support for /self, a convenient way for getting + information about the currently running task. From Gregory Nutt + (2018-08-18). + * fs/procfs: Add a configuration option to disable environment + variable info. From Gregory Nutt (2018-08-19). + * include/endian.h and libs/libc/endian: Add support for endian.h. + From Gregory Nutt (2018-08-19). + * include/sys/param.h: Add a dummy sys/param.h header file.

It is awkward to use and no longer + necessary now that we have apps/examples/calib_udelay. From Gregory + Nutt (2018-08-19). + * arch/arm/src/stm32f7/stm32_serial.c: Previous logic would invalidate + the data cache as each byte was read from the DMA buffer.

From Xiang Xiao (2018-08-23). + * mm/: add mm_heapmember function and reimplement kmm_heapmember base + on mm_heapmember since this function is very useful if multiple heaps + exist. From Xiang Xiao (2018-08-23). + * pthreads: Add support static pthread stack. Add standard + pthread_attr_setstack() and pthread_attr_getstack().

From Gregory + Nutt (2018-08-24). + * arch/arm/src/kinetis: I2C ensure timeout on bus error. The code had + a dead wait on I2C_S_BUSY. Noise on the bus would cause the driver to + hang.

From Gregory Nutt + (2018-09-18). + * drivers/usbdev: Fix buffer overrun check in rndis.c. The RNDIS driver has + been working since 13 Nov 2017. However, I finally found that it depends + on network and buffer configurations. If a receiving TCP packet is + divided into smaller ones based on USB max packet size, this condition + check works correctly. From Masayuki Ishikawa (2018-09-20). + * - mtd/progmem: change up_progmem_npages to up_progmem_neraseblocks + + page is a unit for read/write operation. + eraseblock is a unit for erase operation. + up_progmem_npages is a little bit confusing because it returns number of + erase blocks in flash memory.

From Gregory Nutt (2018-09-21). + * arch/arm/src/kinetis: Remove all attempts to reprioritize interrupts. + From Gregory Nutt (2018-09-21). + * arch/arm/src: Correct all ARMv7-M architectures. Interrupts were not be + disabled correctly on power up. Writing zero to the NVIC SET-ENABLE + registers has no effect. In order to disable interrupts, it is necessary + to write all ones to the NVIC CLEAR-ENABLE register. Noted by David + Sidrane. From Gregory Nutt (2018-09-21). + * net/tcp/tcp_recvwindow.c: In order to receive data we must not only have + IOBs available, but we must also have at least one IOB chain qentry + available. Otherwise, we will advertise that we an buffer a lot of data + when, in fact, we cannot. This is an experimental fix to a performance + problem noted by Masayuki Ishikawa. From Gregory Nutt (2018-09-22). + * fs/driver: Add support for named MTD drivers in the pseudo file system. + This will, eventually, allow us to mount file systems that need MTD + drivers without having to fake an intervening block driver. + fs/driver and fs/mount: Add mount() support for file systems that require + MTD drivers (vs. block drivers). From Gregory Nutt (2018-09-22). + * include/sys/socket.h: Renumber the socket types. They must begin at 1, + not zero. Socket type zero has a special meaning for some interfaces. For + example, getaddrinfo() uses a socket type of zero to many any type of + socket. The is no standard name for the any-type-socket, but macOS uses + SOCK_UNSPEC. NuttX will do the same. Issue noted by Anthony Merlino. + From Gregory Nutt (2018-09-24). + * Brings in an initial port of version 0.3.7 of Peter Anderson's SPIFFS + flash file system into NuttX. From Gregory Nutt (2018-09-24). + * arch/arm/src/imxrt/imxrt_enet.c: The board would not come up if I ran + Nuttx from cold. I dumped the PHY registers to see what the differences + were and the PHY was coming up in NANDTree mode. This is a mode for + testing connectivity between the PHY and the MAC. Switching this mode off + in the PHY registers has fixed the problem. From Dave Marples (2018-09-25). + * net/tcp/tcp_wrbuffer.c: Fix buffer release handling on failed buffer + alloc.

This was changed multiple times, but + should be fixed now. From Anthony Merlino (2018-09-25). + * include/nuttx: Fix definitions used to access OS functions within the + libraries. In the FLAT build, we must always set the errno and/or create + cancellation points because the same library functions are used within the + OS as are used by applications. This could cause issues for the OS but + corrects some problems at the user interface. Noted by Federico + Braghiroli in Bitbucket issue 121. From Gregory Nutt (2018-09-26). + * arch/arm/src/imxrt: Add LPI2C driver. From Ivan Ucherdzhiev (2018-09-26). + * arch/arm/src/imxrt/imxrt_lpsrtc.c: SVNC LPCR register bits 0 & 1 are NOT + reserved and are, in fact, needed to enabled the SRTC. Now the SRTC is + working. From Ivan Ucherdzhiev (2018-09-26). + * arch/arm/src/imxrt/imxrt_enet.c: Fix a race condition in setting up the + Ethernet Tx transfer. From Dave Marples (2018-09-26). + * arch/arm/src/lc823450: MPU support for FLAT build From Masayuki Ishikawa + (2018-09-27). + * Corrections for the i.MXRT Ethernet: + + (1) Now the Ethernet is completely re-initialized when an error occurs by + means of taking the interface down and back up but the PHY is _not_ + renegotiated for that case because that is very time consuming and an + error in the Ethernet is no reflection on the state of the PHY anyway. + (2) Explicitly sets the expected PHY address to zero (this could be moved + into the config) rather than searching for it which takes ages, and + it's zero anyway for this board (that's the broadcast address, and + anything that cannot respond on that has multiple PHYs, so that would + be a new board). + (3) Allows for the renegotiation of the PHY to be optional when a reset is + needed. If a non-renegotiated reset doesn't result in good comms to + the PHY then it'll automatically be escalated to a renegotiated one. + (4) Only performs a reset for errors that need it (the CRITICAL_ERROR + define). The list of errors that need reset are somewhat arbitrarily + chosen based on my prejudices and might need to be revisited, but + certainly the jabber errors don't need reset, the partial packet is + thrown away by the layer above anyway. + (5) Re-loads the multicast table on reset. + (6) Adds a bit more logging into the imxrt Ethernet module. From Dave + Marples (2018-09-28). + * fs/spiffs: SPIFFS is basically functional although still immature.

From Gregory Nutt (2018-10-01). + * EFM32, STM32 (FS/HS), STM32F7, and STM32L4 OTGFS/HS: Th epin_configure() + function used the same eptype as the TxFIFO number for all endpoints. + This should probably be the physical EP number, not the EP type. + Suggested by Key Two. From Gregory Nutt (2018-10-02). + * libs/libc/stdio/lib_sscanf.c: Fix conversion for format specifiers that + appear right after a floating point format specifier. When performing a + floating point conversion the parsing code could consume more than + required characters from the input buffer.

From Gregory Nutt (2018-10-21). + * Fix the LPC4330 family SDMMC card access. Some of these fixes (e.g. DELAY + register) may also be applicable elsewhere. These are _NOT_ extensively + tested, but they are certainly better than the current state of the + driver. The fixes, specifically, are; + + - Clocks were wrongly configured - way too fast because there is no + primary divider on LPC4330 + + This is fixed by means of changing the definitions in the board.h file. + I've edited the one for the lpc4330-xplorer board because I'm actually + working with Versiboard and don't want to contribute that config just + yet while I've still got the drains up on it. + + - The LPC43_SDMMC_DELAY register was not being set + + I suspect, in the 'real world', it's possible to get away without + setting this, but I've added a register definition, default value and + register access macros into arch/arm/src/lpc43xx/chip/lpc43_scu.h and + then used them in arch/arm/src/lpc43xx/lpc43_sdmmc.c. + + - The LPC43_SDMMC_BLKSIZ and LPC43_SDMMC_BYTECNT registers had the wrong + values. + + The management have already implemented a rather nice block level + interface for the stm32 so I've just re-used that to write to these + registers as required. I'm slightly nervous that accessing the + configuration registers (SCR being the prime example) which has a much + smaller block size may not be being done in the right way but it does + seem to work correctly, so let's assume it's all OK until someone tells + me otherwise. + + These fixes have been tested with DMA-based read/write on a LPC4330. Speed + via nsh is pretty low but I'm assuming that's just a + buffering/implementation issue for now. From Dave Marples (2018-10-21). + * arch/arm/src/lpc54/lpc54_sdmmc: Port Dave Marple's LPC43 USB DCD fix to + the LPC54 with appropriate naming changes.

From Anthony Merlino (2018-12-18). + * crypto/aes.c: This commit provides an improved AES cipher API in + addition to the existing routines. The reasons for this new API are: + 1) better performance, giving the possibility to avoid re-setting-up + the key for each AES block when the same key is used multiple times. + This is important for the current single user of AES, which is related + to storage and FTL. And 2) suitable for simultaneous use of multiple + AES keys, which will be required by the upcoming crypto framework. It + retains compatibility with the previous API, so there is no need to + change anything else right now. From Sebastien Lorquet (2018-12-18). + * arch/ assertions: Correct duplicated logic from commit + dbf01d12b7321d1b48b68d3b69842a853b049376. Checking for PID == zero is + not a valid way to test for the IDLE task in all configurations! This + is only true in the single CPU configuration. In multiple CPU + configurations, there will be a separate IDLE task for each CPU with a + different PID and an alternative check must be used. NOTE: The logic + fixed in somes places still lacks sufficient intelligence to find the + right stack for the CPU IDLE thread and could still show the wrong + stack. From Gregory Nutt (2018-12-18). + * Change RNDIS mac: + - configs/lc823450-xgevk: Change RNDIS MAC address assignment. In + previous implementation, mac[0] was assigned to 0xaa for RNDIS host + to avoid MAC address conflicts with RNDIS device.. However, I + noticed that this assignment causes a random MAC address generation + on ubuntu16.04 or later which is inconvenient to set up network + interface. This new assignment scheme fixes this issue. + - configs/viewtool-stm32f107: Change RNDIS MAC address assignment. + Same issue. + From Masayuki Ishikawa (2018-12-19). + * crtypo/: This change: + - Avoids the use of up_aesinitialize() entirely, which resolves + dependency problems, because this function does not make sure that an + actual hardware aes implementation was made available: each SoC is + now responsible to ensure the AES hardware is initialized before + first use. This applies to lpc43xx, stm32 and sam34. + - Remove definitions of the NEVER used aes_init and aes_update + operations. The new AES API will be more suitable. + - Change the unusual naming in stm32 (avoiding possible naming clashes) + - Change the unusual naming in sam34 (avoiding possible naming clashes) + - Add some FAR to pointers and enforce the 80 col limit in stm32 and sam + From Sebastien Lorquet (2018-12-19). + * arch/arm/src/stm32: Add support for DMA v1 CSELR support.

From Anthony Merlino (2018-12-19). + * Revert "This patch prevent heap corruption as in below case." This + solution to the problem noted by EunBong Song results in major memory + fragmentation and and out-of-memory conditions on the PX4 platform. On + that platform the lower priority work queue is very low priority and + essentially never runs when the system is busy. As a result, the + systems gets slowly starved of memory until failures and bad behaviors + begin to occur. This reverts commit + 91aa26774b291fa553f701ce5222e56a6156c323. From Gregory Nutt + (2018-12-20). + * mm/mm_heap/mm_sem.c: This is a candidate replacement for the reverted + change 91aa26774b291fa553f701ce5222e56a6156c323. This change adds a + check to mm_trysemaphore() (the root implementation of both + kmm_trysemaphore() and umm_trysemaphore()). It checks if the that task + that is apparently executing is marked as RUNNING. If not, how could + the non-running task be trying to get the MM semaphore? I think only + in the exact scenario that Eunbong Song has described. So I think the + solution should provide the same protection as + 91aa26774b291fa553f701ce5222e56a6156c323 but without the horrific + consequences to memory usage.

When the holder is running we can add a holder count. If there + is no holder OR it is not running we want to try to take the semaphore. + There will not be a count if the task is the holder and not running + because it already holds the count. This will result it the deferred + free. We will take it when not held and do the free when we can get + the count because there was no holder. From David Sidrane (2018-12-20). + * Extends the MTD configdata device with the following features / + additions: + 1.

However, + Those changes used an internal OS interface (sched_self()) which is not + available when the the user-space memory manager is built in the + PROTECTED or KERNEL builds and resulted in build failures. This commit + repartitions the logic by moving some of the changes from mm_sem.c into + task_getpid.c.

The next time getopt() + is called, this logic should detect the bad state and force the state + of getopt() to be re-initialized so that it can be reused. This logic + is not full proof (it would fail, for example, if you tried to parse + the same command line twice) but should catch the typical misuse + cases. From Xiang Xiao (2019-02-05). + * drivers/ioexpander/tca64xx.c: Fix some errors in the TCA64XX driver. + From Bruno Schwander (2019-02-06). + * configs/stm32f769i-disco/src/stm32_appinitialize.c: Florian R. + Hölzlwimmer reports that stm32_appinitialize.c often has missing OK and + NULL definitions. This should be fixed by including sys/types.h where + they are defined. From GregoryN (2019-02-06). + * libs/libc/stdio: Add newlib-nano fprintf as an option. This fprintf + code was originally adapted from AVR libc and provides improved + floating point output support, including 'g' mode and making 'f' mode + include digits past the decimal by default. However, this version does + not have any long long support. On a demonstration cortex M4 build, + this version saves about 5kB of ROM. The newlib version can be found + here: https://salsa.debian.org/electronics-team/toolchains/newlib-nano + . That project is GPL overall, but the newlib-nano printf portions are + BSD licensed as described in the COPYING.NEWLIB file. From Keith + Packard (2019-02-06). + * - arch/misoc/src/minerva: Add support for the Minerva architecture + - configs/Kconfig and misoc/nsh/defconfig: Add support for the + Verilator board. + From Ramtin Amin (2019-02-07). + * tools/lowhex.c: Fix an initialization problem that was causing some + odd behavior at the beginning of lines. From Gregory Nutt (2019-02-07). + * tools/rmcr.c: Add a tools to remove carriage returns and dangline + whitespace at the end of lines. From Gregory Nutt (2019-02-07). + * tools/nxstyle.c: Can now detect if the C comment closing is not on a + separate line. From Gregory Nutt (2019-02-08). + * tools/nxstyle.c: Make sure that all files begin with a comment on line + 1 (which should be the file header). From Gregory Nutt (2019-02-08). + * include/: Correct naming of standard header file. Should be dlfcn.h, + not dllfcn.h. From Gregory Nutt (2019-02-09). + * configs/launchxl-cc1312r1: Add support for on-board LEDs and buttons. + From Gregory Nutt (2019-02-10). + * configs/launchxl-cc1310: Clone LED and button support from the + launchxl-cc1312r1. The number of LEDs and buttons as well as DIO usage + is identical. From Gregory Nutt (2019-02-10). + * drivers/usbhost/usbhost_cdcacm.c: Fixes to the IOCTL method in + recovery of UART pointer and in names of Termios-related field. From + xhbm (2019-02-11). + * CONFIG_NFILE_DESCRIPTORS=0 can no longer be used to disable the file + system. NuttX with no file system does not make sense and is no longer + supported. From Gregory Nutt (2019-02-11). + * configs/sama5d2-xult: Move console from FLEXCOM4 to UART1. FLEXCOM4 + does not work for the Arduino serial. UART1 is used with the VCOM + provided by the EDBG. From Gregory Nutt (2019-02-11). + * Fix conditional logic: The setup seems to support a network without + sockets (CONFIG_NSOCKET_DESCRIPTORS == 0). That is not the case; if + the network is enabled, sockets must be provided. From Gregory Nutt + (2019-02-11). + * configs/launchxl-cc1312r1: Correct DIOs used to provide the UART0 + serial console. Board boots to NSH prompt now. But I am not getting + serial input. Things are probably not very stable in general. From + Gregory Nutt (2019-02-12). + * sched/: Remove the option CONFIG_BOARD_INITTHREAD. Now, if + CONFIG_BOARD_INITIALIZE is selected, then the board_initialize() logic + will ALWAYS run on an internal kernel thread. This will prevent the + problems people have had doing inappropriate board_initialization on + the IDLE thread. From Gregory Nutt (2019-02-12). + * arch/arm/src/tiva: The LauchXL-CC1312R1 NSH configuration is now fully + functional. On to bigger and better things. From Gregory Nutt + (2019-02-13). + * - Move vscanf logic to lib_sscanf.c Switched to stream interface + (tricky, because the old implementation used massive read ahead, which + isn't suitable for streams, chars already read are gone). + - Added scanf and fscanf + - Added hh, h, and ll modifiers + - Fixes for standard compliance in scanf + - Fixes for standard compliance in strto... function family (don't + consume single '-' or '+', allow sign in strotul(l)) + From Johannes (2019-02-14). + * net/tcp/tcp_send_buffered.c: Fix assertion crash when window size is + zero. From Gregory Nutt (2019-02-14). + * net/: The value ERROR should never be returned from internal OS + functions. That is reserved for returning values to appliations with + the errno value set. Within the OS, errors are returned with a negated + errno value ALWAYS. From Gregory Nutt (2019-02-14). + * libs/libc/stdio/lib_libsscanf.c: Initialized the lastc pointer to avoid + the checks for NULL. Removed a bug in the floating point parsing which + allowed several signs after each other. From Johannes (2019-02-14). + * tools/nxstyle.c: Add check for multiple definitions of local variables + on a line. From Gregory Nutt (2019-02-14). + * libs/libc/stdio/lib_libvsprintf.c: No precision specifier resulted in + precision 0 but should be precision 6. From Johannes (2019-02-15). + * libs/libc/stdio: Add support for %g format which, for these purpose, + is equivalent to %f except that trailing zeroes are suppressed. From + Gregory Nutt (2019-02-15). + * libs/libc/stdio: In the recent changes we lost the implementation of + vsscanf(). This commit restores vsscanf(). sscanf() is not just a + front end for vsscanf(). From Gregory Nutt (2019-02-15). + * libs/libc/stdio: Remove unused, non-standard functions lib_sscanf() + and lib_sprintf(). From Gregory Nutt (2019-02-15). + * libs/libc/stdio/nano_libvsprintf.c: Add long long support. + CONFIG_LIBC_LONG_LONG needs at least CONFIG_NANO_PRINTLEVEL 2. Code + size for compile without CONFIG_LIBC_LONG_LONG shouldn't be affected. + From Johannes (2019-02-15). + * nuttx/sched/mqueue: Change 'int prio' to 'unsigned int prio'. + According to open group specification, priority field in mq_* functions + should have unsigned type: + http://pubs.opengroup.org/onlinepubs/9699919799/basedefs/mqueue.h.html + From Michał Łyszczek (2019-02-15). + * arch/arm/src/tiva/hardware: Add CC13x0 and CC13x2 I2C header files. + From Gregory Nutt (2019-02-16). + * syscall/syscall.csv: Change to mqueue function protothypes must be + reflected in the KERNEL mode proxies as well. From Gregory Nutt + (2019-02-16). + * libs/libc/stdio/Make.defs: lib_dtoa.c is only used in the + LIBC_CONFIG_NANO_PRINTF=n case. From Johannes (2019-02-16). + * Restore lib_sprintf(). It was removed because I thought was not used. + But I was wrong; there is logic in drivers/syslog that depends on + lib_sprintf(). From Gregory Nutt (2019-02-16). + * arch/arm/src/tiva/hardware/tiva_wdt.h: Add WDT register definition + header file for all LM, Tiva, and CC13xx parts. From Gregory Nutt + (2019-02-16). + * - arch/arm/src/stm32f0l0: SPI support for F0 + - arch/arm/src/stm32f0l0/Kconfig: L0 parts should select + STM32F0L0_STM32L0 + - arch/arm/src/stm32f0l0/hardware: unify names for ADC/DAC/DMA/CAN + - drivers/wireless/lpwan/sx127x/sx127x.c: return immediately when ISR0 + is called but sx127x is not initialized + - configs/nucleo-f091rc: support for sx127x + - configs/b-l072z-lrwan1/include/board.h: use HSI as default clock + source and fix typo in SPI1 pins. + From Mateusz Szafoni (2019-02-16). + * libs/libc/stdio/lib_dtoa.c: Lots of risky turmoil to get this file + closer to the NuttX coding style. Seems to check out, but still + risky. libs/libc/stdio/lib_libdtoa.c: A fix for the %g format. The + algorithm will sometimes generate number greater than the precision of + type double. This adds a check if the precision has been exceeded and + logic to remove the least significant garbage. From Gregory Nutt + (2019-02-16). + * libs/libc/stdio/nano_libvsprintf.c: Added hh type modifier (without + extending the flag variable). From Johannes (2019-02-17). + * tools/nxstyle.c: Beef up logic that detects multiple variable + definitions per line. From Gregory Nutt (2019-02-17). + * libs/libc/stdio: This commits makes the nano-printf the defualt logic + for the printf family. The legacy printf is still available via + CONFIG_LIBC_PRINT_LEGACY. This commit also modifies the nano-prinf + configure: The PRINT_LEVEL is not long selectable. Instead, a not + CONFIG_LIBC_PRINT_MINIMAL boolean setting was added and the PRINT_LEVEL + is derived from a combination of CONFIG_LIBC_PRINT_MINIMAL, + CONFIG_LIBC_FLOATINGPOINT, and CONFIG_LIBC_LONG_LONG. From Gregory + Nutt (2019-02-17). + * libs/libc/stdio: Rename lib_dtoa.c to legacy_dtoa.c; rename + lib_libvsprint.c to legacy_libvsprintf.c From Gregory Nutt (2019-02-17). + * libs/libc/stdio: Rename all nano_*.c and nano_*.h files to lib_*.c and + lib_*.h to emphasize that these are now the defaults, not an optional + implementation. From Gregory Nutt (2019-02-17). + * arch/xtensa/src/esp32/esp32_timerisr.c: Fix backward comparison. From + Gregory Nutt (2019-02-17). + * libs/libc/stdio/lib_libvsprintf.c: Adds configurable support for + numbered arguments. From Johannes (2019-02-18). + * libs/libc/stdio/Kconfig: Need to guard LIBC_NUMBERED_ARGS against + LIBC_LEGACY_PRINTF From Johannes (2019-02-18). + * - sched/init/nx_start.c: Add support for + CONFIG_BOARD_DRIVER_INITIALIZE. If this option is selected then + nx_start() will call a board-provided function board_early_initialize() + immediately after calling up_initialize(). + - Rename CONFIG_BOARD_INITIALIZE to CONFIG_BOARD_LATE_INITIALIZE. + - Rename board_initialize() to board_late_initialize() + From Gregory Nutt (2019-02-18). + * include/nuttx/compiler.h: Important fix for C++ users. compiler.h was + using the value of __STDC_VERSION__ to determine if inline functions + are supported or not. If not then the keyword inline was defined out. + Good for C but bad for C++ because C++ does not defined + __STDC_VERSION__ at all. C++ applications may draw in compiler.h + indirectly via other head files and this can result in C++ compiler + problems since 'inline' is defined out. This fix is to ignore the + (undefined) __STDC_VERSION__ if __cplusplus is defined. From Gregory + Nutt (2019-02-19). + * include/nuttx/elf.h: Adds missing extern "C" __cplusplus guard. From + Anthony Merlino (2019-02-19). + * libs/libc/stdio/lib_libvsprintf.c: Cleaned naming and allow for leading + zeros in argument number (which doesn't make sense but should be). + From Johannes (2019-02-19). + * arch/arm/src/stm32f7/stm32_i2c.c: Fix another memory access issue on a + bus error. From David Sidrane (2019-02-19). + * arch/arm/src/stm32h7 and stm32l4: Apply David Sidrane's fix for the + STM32F7 to the STM32L4 and STM32H7. The same change might be + appropropriate to STMF0/LO and STM32, but the patch does not apply + cleanly. It would have to be manually checked. From Gregory Nutt + (2019-02-19). + * libs/libc/stdio/Kconfig: CONFIG_LIBC_NUMBERED_ARGS now depends on + EXPERIMENTAL. Per Johannes: I tested numbered arguments on i.mx rt + 1050, and it isn't working. Only on Linux/MSYS 64bit all relevant data + types are size 8 bytes, and therefore my loop through the arg list is + working. On 32bit systems, all is 4 bytes except floating point + variables which is implicit 8 byte double. From Gregory Nutt + (2019-02-20). + * libs/libc/stdio/lib_libvsprintf.c: Fix typo: PRINTF_LEVEL, not + PRINT_LEVEL. From Gregory Nutt (2019-02-20). + * - libs/libc/stdio/lib_vsprintf.c and Kconfig: Numbered arguments now + work by using two pass parsing and an argument list. The maximum + number of numbered args is determined by CONFIG_LIBC_NL_ARGMAX which + is then copied into NL_ARGMAX. Size of pointer argument ('p') is + determined before output. + - include/limits.h: Define NL_ARGMAX (as well as some of the other + 'invariant values' per + http://pubs.opengroup.org/onlinepubs/7908799/xsh/limits.h.html) + From Johannes (2019-02-21). + * libs/libc/lib_libvsprintf.c and Kconfig: Remove + CONFIG_LIBC_PRINT_MINIMAL. The output in that configuration is + unsatisfactory and inappropriate for use with NuttX. For example, the + output from many NSH commands become corrupted and useless. Doesn't + belong in this context. From Gregory Nutt (2019-02-21). + * libs/libc/stdio/Kconfig: Add 'range 9 999999' to + CONFIG_LIBC_NL_ARGMAX. Per OpenGroup.org, the minimum value for + NL_ARGMAX is 9. From Gregory Nutt (2019-02-21). + * include/poll.h: Remove un-named union from 'struct pollfd'. It is not + required by OpenGroup.org and violates the NuttX C coding standard + because it is not C89 compatible. From Gregory Nutt (2019-02-21). + * imxrt_adc: Error in offset From David Sidrane (2019-02-22). + * drivers/net/tun.c: Re-order all TUN/TAP driver state data. Not only + was was with wasting memory due to alignement requirements, it was also + causing network packet buffers to be improperly aligned causing + problems because the network requires 16-bit packet buffer alignment + for uint16_t accesses. This alignment problem was discovered by Alan + Carvalho de Assis. From Gregory Nutt (2019-02-24). + * drivers/net/tun.c: Packet buffer size should include the configured + GUARD_SIZE. And, given how the buffers are allocated, the allocation + size must be an even number of 16-bit values to preserve alignment. + From Gregory Nutt (2019-02-24). + * drivers/net/tun.c: Cosmetic changes from review for coding style + compliance.

From David Sidrane (2019-02-25). + * libs/libc/pthread, syscall/, and include/sys/syscall.h: Support for + pthread_mutex_timedlock() was added recently, however no new system + call was added for the API make is usable only in the FLAT build. With + a pthread_mutex_timedlock() system call, there is no reason for a + pthread_mutex_lock() system call since it is now nothing more than an + wrapper around pthread_mutex_timedlock(), passing NULL for the time + value. The pthread_mutex_lock() syscall was removed and the + pthread_mutex_lock() implemented was moved from /sched/pthread to where + it now belows in libs/libc/pthread. From Gregory Nutt (2019-02-25). + * configs/nucleo-l073rz/src/stm32_buttons.c: By default button support + is enabled.

This makes it possible to have multiple + instances of the NX server running on boards that support multiple + displays. Also includes updates to boardctl() to accept display number + paramters. From Gregory Nutt (2019-03-10). + * Add three patches about STM32 intherupts and network loopback files + - Add the missing macro STM32_IRQ_NIRQS used by + ./arch/arm/src/stm32f7/stm32_irq.c + - The struct in_addr doesn't have the member sin_addr. + - The function lib_lo_ipv6match() is for IPv6. Correct the function it + calls from lib_lo_ipv4matchto() to lib_lo_ipv6match(). Also add + CONFIG_NET_IPv6 for configuration. + From Kejun ZHOU (2019-03-11). + * arch/arm/src/stm32h7: initial support for protected build mode. Not + functional yet. It compiles without errors and passes initialization + but after entering the user app strange things happen. From Mateusz + Szafoni (2019-03-11). + * tools/nxstyle.c: Fix logic error that prevent detecion of '/' and '/=' + as operators. net/: Minor updates resulting from testing + tools/nxstyle. From Gregory Nutt (2019-03-11). + * arch/arm/include/nrf52/ and arch/arm/src/nrf52: 1. Added 52840 family + support 2. Use common irq and memory layout header file for 52832 & + 52840. From Levin Li (2019-03-12). + * binfmt/nxflat.c: Correct a double free debug assertion. This occurs + when groups are enabled: (1) once via binfmt_exit and unload_module, + and (2) once via sched_releasetcb(). this was corrected by adding + logic to free/unload the memory once and nullify the pointer so that + cannot be freed a second time. This commit resolves Bitbucket issue + #145. From Valmantas Palikša (2019-03-12). + * binfmt/nxflat.c: Update to last NxFLAT change: The logic must respect + the reference count before freeing the dspace memory region. From + Gregory Nutt (2019-03-12). + * tools/nxstyle.c: Don't complain about certain lowercase characters in + otherwise uppercase pre-processor identifers: IPv6, IPv4, ICMPv6, + IGMPv2, p as a decimal point, d signifying a divisor. It was a bad + idea to let the door open a crack for there. While they improve + readability, the inconsistently also causes other problems. From + Gregory Nutt (2019-03-12). + * arch/arm/src/nrf52: 1. added RNG device driver 2. added errdata to + correct temp which will be used by RNG module 3. use general + task_trigger / event_clear inline api for all driver. From Levin Li + (2019-03-13). + * include/nuttx/nx/nxmu.h: Remove prototype of non-existent function. + From Gregory Nutt (2019-03-13). + * This commit removes naming associated with and naming for the now + non-existent NXFE graphics layer. + - graphics/: Rename nxfe_reportposition to nxmu_reportposition.

There is no long an + nxfe layer. + - graphics/: Rename nxfe_state_s to nxmu_state_s. There is no longer + an nxfe layer. + - graphics/: Rename nxfe_conn_s to nxmu_conn_s. There is no longer an + nxfe layer. + From Gregory Nutt (2019-03-13). + * - graphics/: nx_openwindow() and nxtk_openwindow() now accept an + additional 'flag' parameter. This argument is not used at present but + will, eventually enable a RAM backed, per-window framebuffer. + - graphics/Kconfig: Add configuration to support a rambacked + framebuffer. Current marked as EXPERIMENTAL because this is a work in + progress. + From Gregory Nutt (2019-03-13). + * A little more progress toward the implementation of per-window + framebuffers. + - graphics/: Add logic to allocate the per-window framebuffer. + - graphics/: A few fragmentary thoughts on how a per-window + framebuffer could be represented and allocated. + Still missing: + - Logic that generates the low lever framebuffer renderers for the + per-window framebuffers, + - The logic that picks off the per-window framebuffer updates from + normal graphics device updates. This logic must update both the + per-window framebuffer and the graphics device (from the framebuffer). + From Gregory Nutt (2019-03-14). + * graphics/nxflig/pwfb: Clone logic for new bit blitters for per-window + framebuffers. From Gregory Nutt (2019-03-14). + * configs/teensy-3.x/usbnsh/defconfig: Fix a mismatch in types.

From Sebastien Lorquet + (2019-03-14). + * arch/arm/src/armv7-a/mmu.h: pdating the cp15_wrttb and cp15_wrdacr + functions to use inline assembly in the correct way. The incorrect + method was generating errors as ARMv7-a expects the MCR/MRC + instructions to provide registers as an argument(MRC p15, 0, , c2, + c0, 0) and the code was providing a constant value(and hence the build + error). From Bilal Wasim (2019-03-14). + * This commit brings the per-framebuffer logic to code-complete. Still + untested. + - graphics/nxbe: The moverectangle renderer now supports updates to + the per-window framebuffer (unclipped) as well as the graphics device + memory (clipped). + - graphics/nxbe: The filltrapezond renderer now supports updates to + the per-window framebuffer (unclipped) as well as the graphics device + memory (clipped). + - graphics/nxbe: The getrectangle method now returns data from the + per-window framebuffer if available. + - graphics/nxbe: The fillrectangle renderer now supports updates to + the per-window framebuffer (unclipped) as well as the graphics device + memory (clipped). + - graphics/nxmu: If a window supports a per-window framebuffer, then + redraw callbacks are suppressed and the device content is updated + from the shadow, per-window framebuffer. graphics/nxbe: The + copyrectangle renderer now supports updates to the per-window + framebuffer (unclipped) as well as the graphics device memory + (clipped). + - graphics/nxbe/nxbe_setsize.c: Reallocate the per-window framebuffer + when the window size changes. + From Gregory Nutt (2019-03-15). + * configs/nucleo-f446re: Add support for the Nucleo F446RE. From + Sebastien Lorquet (2019-03-15). + * Fix defconfigs. A few people have been lazy or are perhaps ignorant of + the procedures. But the have been committing .config files as though + they were defconfig files. Wrong, wrong, wrong. defconfig files are + specially formatted files that you create through 'make defconfig'. + From Gregory Nutt (2019-03-15). + * configs/open1788/nxlines/defconfig: Enable anti-aliasing. From + Gregory Nutt (2019-03-15). + * configs/open1788/pwfb: Add an example for testing per-window frame + buffers. arch/arm/src/lpc17xx: Add a configuration option to skip + over the framebuffer when adding DRAM to the heap. graphics: Early + fixes from testing per-window framebuffer.

Use + CONFIG_DEBUG_GRAPHICS instead of CONFIG_DEBUG_FEATURES in most cases. + - graphics/: Nothing under graphics/ should set the errno. + From Gregory Nutt (2019-03-17). + * libs/libnx/nxtk/nxtk_setsize.c: Add logic to redraw NXTK borders for + the case of per-window framebuffers. There are no redraw callbacks in + this case, so we cannot rely on the callbacks to redraw the borders. + From Gregory Nutt (2019-03-17). + * configs/lc823450-xgevk: Remove -nostdinc to avoid build error From + Masayuki Ishikawa (2019-03-18). + * libs/libc/libc.csv: Should be locale.h not local.h.

From Mateusz Szafoni (2019-03-24). + * arch/arm/src/stm32/stm32_pwm.c: Missing commas in initializers can + break compilation in certain configurations. From Mateusz Szafoni + (2019-03-24). + +7.30 2019-05-19 Gregory Nutt + + * arch/ and config/ files: All board interfaces (those starting with + board_) must be defined in board-specific logic. Otherwise, they cannot + be customized for specialized usage by different boards. The + board_reset() interface was defined in architecture-specific logic that + only called up_systemreset(). That is useless! This change removes the + board_reset() implementation from the architecture-specific code and + re-implements it in the src/ directory of each board that has + CONFIG_BOARDCTL_RESET enabled. That is the correct functional + partitioning. From Gregory Nutt (2019-03-25). + * configs/omnibusf4/src/stm32_reset: Add boardctl() reset logic. From + Bill Gatliff (2019-03-25). + * arch/arm/src/stm32f7/stm32_qspi.c: Fix QuadSPI interrupts. This commit + essentially replaces wrongly named configuration variables + STM32F7_QSPI_INTERRUPTS into CONFIG_STM32F7_QSPI_INTERRUPTS. Also fixes + some getreg/putreg where register addresses were used instead of + register offsets From Pierre-Olivier Vauboin (2019-03-25). + * graphics/nxmu, include/nuttx/nx/nxmu.h, libs/libnx: Add new + server->client callback to notify the window client of server events. + Remove the old 'blocked' callback and just make it one case of an 'event' + callback. From Gregory Nutt (2019-03-25). + * graphics/ and libs/libnx: Implement new interfaces nx_synch() and + nxtk_synch(). This are used to synchronize the NX server with the window + client. Currently most of the logic is equivalent to nx_block() and + nxtk_block(), but with slightly different semantics. They are separate + now because they are likely to diverge in the future. From Gregory Nutt + (2019-03-25). + * configs/stm32f103-minimum/src/: USB reset was not working appropriately + since the pin connected to D+ was incorrectly defined and the pullup/down + logic was reversed. From Matias N (2019-03-25). + * configs/omnibusf4: Add board_ioctl() which is needed only if + CONFIG_BOARDCTL_IOCTL=y is selected; Update NSH configuration to enable + board IOCTLs and DFU mode reset. From Bill Gatliff (2019-03-26). + * include/limits.h: Remove the duplicate TMP_MAX definitions. The + standard requires that TMP_MAX defines be in stdio.h. From Xiang Xiao + (2019-03-26). + * include/sys/select.h: Fix compiler error when CONFIG_NSOCKET_DESCRIPTORS + is undefined. From Xiang Xiao (2019-03-26). + * arch/arm/src/armv7-a/Toolchain.defs: Fix 'cc1: warning: switch + -mcpu=cortex-a7 conflicts with -march=armv7-a switch' From Xiang Xiao + (2019-03-26). + * drivers/usbdev/cdcacm.c: This fixes a problem where the host sent a "get + descriptor" message of type "standard" with a recipient of type + "interface". Since the composite driver would only pass messages to the + child interfaces when a message was not "standard", this message was not + handled. I changed the condition so that the composite driver checks not + only if this is a "standard" message but if it is also directed to the + device. Otherwise, the handling is delegated to the children of the + composite device. From Matias N (2019-03-26). + * drivers/video/max7456.c: Adds a read-only (for now) /dev/osd0/CM + interface for obtaining the chip's onboard NVM character map data. Use + seek() to position the cursor over a desired subset of bytes, or request + a large read to obtain the entire EEPROM memory contents. Values are + returned in binary form.

From Matous Pokorny (2019-03-29). + * configs/boardctl.c, include/sys/boardctl.h: Add a command to start the + VNC server. From Gregory Nutt (2019-04-02). + * drivers/syslog/syslog_stream.c: In syslog buffered mode, avoid IOB alloc + lock-up with heavy network activity. This change alters the buffered + syslog logic to use 'iob_tryalloc' instead of blocking 'iob_alloc' to + avoid syslog printing from getting stuck when all IOBs are depleted by + network activity. An issue was seen when large incoming TCP transfer + uses free IOB buffers and processing threads try to use syslog which then + block at iob_alloc. From Jussi Kivilinna (2019-04-03). + * arch/stm32f7: Support bypassing the input clock divider on the SDMMC + interface. This enables using the full clock speed provided to the SDMMC + interface with no dividing.

From Erik Englund (2019-04-03). + * PIC32MZ: The commit corrects the gpioirq when mismatch mode is selected + and add support for edge detect mode. Slew Rate was also added for + completeness. From Abdelatif Guettouche (2019-04-03). + * libs/libc/stdio/lib_libvsprintf.c: Restore support for printing NULL + string as "(null)".

Commit + 2bc709d4b99447f8decdc7580fdabab6dd8939b1 was intended to handle the case + where up_timer_gettime may not start from zero case. However, this + change has the side-effect of breaking every implementation of tickless + mode: After this change the tickless timer structures are used before + they are initialized in clock_inittime(). Initialization happens later + when up_initialize is called() when arm_timer_initialize(). + + Since the tickless mode timer is very special, one solution might be to: + (1) Rename xxx_timer_initialize to up_timer_initialize, (2) Move + up_timer_initialize to include/nuttx/arch.h, and (3) Call it from clock + subsystem instead up_initialize. Basically, this change make timer + initialization almost same as rtc initialization(up_rtc_initialize). For + now, however, we just need to revert the change.

This driver can be used with the BMI160 sensor + connected over SPI or I2C bus + configs/spresense: enable BMI160_I2C sensor over I2C on spresense board. + From Alin Jerpelea (2019-06-20). + * drivers/usbhost/usbhost_composite.c: I'm working on a CDC/ECM driver + and in my driver's usbhost_cfgdesc() function I need access to the + class-specific descriptors. Currently these are not available if the + interface is part of a composite device, since only interface and + endpoint descriptors are copied by usbhost_copyinterface(). This commit + will also copy any class-specific interface descriptors for use in + downstream class drivers. NOTE: There's one change that might be + incorrect, where I skip interfaces with zero endpoints. I did this + because my device has two consecutive interface descriptors with the same + interface number, one for altsetting 0 with no endpoints, and another for + altsetting 1 with 1 endpoint. The loop was aborting due to finding two + interface descriptors back-to-back. From Adam Porter (2019-06-21). + * STM32F7 GPIO: Add GPIO driver. Code is inspired from stm32f3discovery + and nucleo-l476rg platforms. Tested on Nucleo-F767ZI. From Phil Coval + (2019-06-21). + * drivers/usbhost/usbhost_composite.c: The cfgdesc pointer was initialized + after the buffer had been advanced, so it was not pointing where it + should. The totallen operations at the end of the function ended up + overwriting memory belonging to the first copied interface descriptor. + From Adam Porter (2019-06-22). + * configs/pnev5180b: Add usbnsh configuration. This is basically the same + as the 'nsh' defconfig, but uses CDC/ACM as the NuttShell console + device. From Michael Jung (2019-06-22). + * STM32 USB OTG FS/HS Host: In stm32_ctrlout() in the HS and FS host + drivers, the data buffer isn't sent.

From + Jukka Laitinen (2019-06-28). + * arch/mips/src/pic32mz/pic32mz-gpio.c: Use LAT instead of PORT when + writing. From Ouss4 (2019-06-28). + * arch/mips/src/pic32mz: Add DMA support. From Abdelatif Guettouche + (2019-06-28). + * configs/olimex-stm32-e407/src: Change initialization to match the way it + is done with other boards. From Gregory Nutt (2019-06-28). + * sched/semaphore/sem_holder.c: Fix a bad assertion. The comments state + correctly that we cannot make any assumptions about the number of holders + of the semaphore, yet the code asserts if there are any holders. This + makes the code behave closer to what the comments say. From Gregory Nutt + (2019-06-28). + * configs/pnev5180b/nsh-cdcecm/defconfig: CDC/ECM requires SCHED_LPWORK + From Gregory Nutt (2019-06-29). + * Various Kconfig files: Kconfig files should not select SCHED_WORKQUEUE + since that is really only is only the logical OR if SCHED_LPWORK and + SCHED_HPWORK. Selecting it has no effect other than to produce an + erroneous configuration. From Gregory Nutt (2019-06-29). + * nrf24l01: Fix PIPENO/PKTLEN bitmask in rx fifo header. In RX fifo + header, the first byte should use 5 lsb to store PKTLEN and 3 msb to + store PIPENO. However, FIFO_PIPENO_SHIFT was set to 4 which causes the + lsb of pipe number to interfere with the received packet size stored in + the fifo. This fix rx corruption when using pipe number > 0. From + Federico Braghiroli (2019-06-29). + * configs/pnev5180b/usbnsh-cdcecm: This new configuration includes a USB + Composite Device with both CDC/ACM and CDC/ECM. NuttShell provides a + terminal via CDC/ACM. A network interface (eth0) is provided via + CDC/ECM. From Michael Jung (2019-06-29). + * tools/nxstyle.c: Tool depends on the file under test containing "Private + Functions" or "Public Functions" block comments.

Fix by moving libgcc into recursive + archive group between --start-group and --end-group. Other + kernel/Makefiles suffer from this same issue From Gregory Nutt + (2019-06-30). + * tools/nxstyle.c: Fix error in conditional logic that was preventing + detection bad brace alignment. Add logic to handle alignment of braces + in data initializators which following slightly different indentation + rules. From Gregory Nutt (2019-06-30). + * tools/nxstyle.c: No warning for declarations that begin in column 1 + within 'extern "C"'. This is because the 'extern "C"' is conditioned on + __cplusplus so the declarations are not normally indented. From Gregory + Nutt (2019-06-30). + * libs/libc/netdb: Implemented the netdb functions getnameinfo(), + getservbyport(), and getservbyport_r(). From Michael Jung (2019-06-30). + * configs/pnev5180b/src/lpc17_romfs: pnev5180b/src/lpc17_romfs: Automount + baked-in ROMFS image. Includes support for linking a binary ROMFS image + into the nuttx executable and for mounting it during board bringup. From + Michael Jung (2019-06-30). + * drivers/usbdev/usbmsc: Fix usbmsc_exportluns declaration. Fixes the + following error "...undefined reference to `usbmsc_exportluns'". From + Alin Jerpelea (2019-07-01). + * configs/spresense: Register the procfs in the NSH configuration. This + is a configuration change in sync with the other ones. Enable + READLINE_CMD_HISTORY, enable by default SPI 4 and 5, and enable SPI to + keep all configurations in sync. From Alin Jerpelea (2019-07-01). + * net/inet: Fix tcp active close in inet_close.c. In previous + implementation, FIN packet was not sent when a socket is actively closed + (e.g. telnetd or webserver) without SO_LINGER. This issue happens + because the socket closing sequence waits for the status.cl_sem only if + lingering timeout is set. However, in many server use-cases, SO_LINGER is + not usually set and even in these cases, FIN packet must be sent + correctly. This changes the logic in inet_close.c so that it can wait + for status.cl_sem regardless of SO_LINGER. Instead, if SO_LINGERis set, + it waits for the semaphore with timeout option. From Masayuki Ishikawa + (2019-07-01). + * net/inet/inet_close.c: Last change removed SO_LINGER socket option + functionality. SO_LINGER was always enabled is CONFIG_NET_SOLINGER was + selected. This change implements a proper version of SO_LINGER. It is + based on new logic to drain the buffered TX data, integrated with network + event notification system. Supports notification when UDP or TCP write + buffer becomes empty. From Gregory Nutt (2019-07-01). + * configs/spresense: Add support for MSC and USB Composite device. Adds + usbmsc configuration. Spresense board does not have buttons and but a + template for gpio buttons that can be connected on the external header + From Alin Jerpelea (2019-07-02). + * drivers/wireless: Fix a passive close when sending a packet in gs2200m.c + From Masayuki Ishikawa (2019-07-03). + * arch/arm/src/tiva: Add a workaround for tiva with qemu. With qemu, + tiva_ifup() hangs because ethernet link status can not be set correctly. + This PR is a workaround to avoid this issue. From Masayuki Ishikawa + (2019-07-03). + * arch/arm/src/cxd56xx: Add driver for hardware image processor device to + enable the hardware image processor set CXD56_GE2D=true. From Alin + Jerpelea (2019-07-03). + * drivers/lcd: Add ILI9340 LCD Single Chip Driver. Required LCD driver + settings: LCD_MAXCONTRAST should be 255, but any value >0 and <=255 will + be accepted. LCD_MAXPOWER should be 1: 0=off, 1=on. From Alin Jerpelea + (2019-07-03). + * drivers/lcd: Add JDI LPM013M091A LCD Driver. From Alin Jerpelea + (2019-07-03). + * configs/spresense: Add support for lpm013m091a LCD, add support for + ili9340 LCD, add a new configuration to support an LCD.

This flash writter is using + the xmodem for firmware transfer for flashing please use: + 'tools/flash_writer.py -s -c /dev/ttyUSB0 -d -b 115200 -n nuttx.spk' + From Alin Jerpelea (2019-07-09). + * Update COPYING file. Tools in the tools/ directory are not intended for + binary redistribution and may not all conform to BSD licensing. From + Gregory Nutt (2019-07-09). + * On the LPC1769 there are two 16 KiB AHB SRAM blocks, which are mapped + back to back at physical address 0x2007C000 and 0x20080000 (i.e. right + below and right above a 512 KiB boundary). Memory from those two blocks + is considered continuous when assigned to a heap. In the protected build + mode, when the memory protection unit is used, though, it must be split + into two MPU regions. This is because MPU regions must be naturally + aligned, and the 32KiB continuous address space of the two 16KiB AHB SRAM + blocks does not start at an address divisible by 32KiB. The only other + configurations that use protected build mode on lpc17xx are currently + open1788/knsh and open1788/knxterm. The LPC1788 has the AHB SRAM blocks + mapped more sanely (from an MPU region point of view), which is probably + why no problems emerged here. Both still compile with my change and + other than wasting an MPU region (which would otherwise remain unused) + should work fine. That said, I have no hardware to confirm.

From jjlange (2019-07-11). + configs/lpc4088-devkit/: Added board configurations for Embedded Artists + LPC4088 Quickstart board. From jjlange (2019-07-11). + * include/fixedmath.h: Regarding the single precision float to/from fixed + point conversions in fixedmath.h, I believe the floating point literals + should be appended with the letter 'f' to avoid (expensive) conversions + from single to double precision, and thereby also avoid (expensive if + done in SW) double point arithmetic (which is what is happening upon + inspection of my disassembly). From rajan gill (2019-07-11). + * arch/arm/src/lpc11xx, arch/arm/include/lpc11xx, + configs/lpcxpresso-lpc1115: Support for the LPCXpresso-LPC1115 and for + the LPC1115 architecture in general was removed after NuttX-7.30.

If a timeout has occurred in the middle of a I2C + transfer, the next I2C interrupt should abort any transfers and send a + stop condition to the corresponding I2C bus. Failure to do so will result + in memory corruption / undefined behavior as priv->msgs points to a + region of memory it doesn't owns anymore after lpc17_40_i2c_start + returns. From Augusto Fraga Giachero (2019-07-25). + * configs/tm4c1294-launchpad/src/tm4c_bringup.c: Enables /dev/userleds + for tm4c1294-launchpad by calling userled_lower_initialize() in + tm4c_bringup(). From Nathan Hartman (2019-07-25). + * arch/arm/src/lpc17xx_40xx/lpc17_40_i2c.c: Calculate the appropriate + timeout for I2C transfers. Depending on the bus frequency and transfer + size, I2C transactions can take quite a bit, so a fixed timeout is not a + good solution. Calculating the timeout at run time poses some overhead + but still better than aborting long transactions. From Augusto Fraga + Giachero (2019-07-25). + * net/udp: Remove net stack dependency from CONFIG_NET_BROADCAST. This + change allows us to use CONFIG_NET_BROADCAST without network stack.

From Daniel P. Carvalho (2019-07-27). + * net/tcp and udp: Fix errors in the new implementation of SO_LINGER. + The tcp_drain() and udp_drain() functions were casting the working + argument to the wrong type, resulting in hangs and abnormal behavior. + There is a complexity in the tcp drain logic when the remote peer + closes the socket before all Tx data has been flushed. Sometimes we + are not notified of this case and wait the entire timeout + unnecessarily. There is a workaround in place in tcp_txdrain(), but + this really should be revisited. From Gregory Nutt (2019-07-27). + * arch/arm/src/lpc17xx_40xx/lpc17_40_ethernet.c: Set speed back to + 10Mbps if 10Mmbps link negotiated. From Augusto Fraga Giachero + (2019-07-27). + * i.MXRT USDHC: This change completes SDIO support for IMXRT, and also + adds support for WiFi using the AP6212A module based on Simon Piriou's + rather excellent work. The patch should also address DavidS's concern + about width setting for USDHC1 and 2. Testing of the WiFi is minimal + so far but functionality is proven. I'm specifically not happy that + the driver doesn't recover elegantly from a DMA data checksum failure, + but that is an issue that can be dealt with in due course ... I'm + trying to get the rest of the interfaces fleshed out and the hardware + proven so it can go for pre-production build. I _think_ there's only + Bluetooth and USB-device left to implement now. From Dave Marples + (2019-07-28). + * arch/arm/src/imxrt/imxrt_clockconfig.c: Enable TRACE clocks if the + divider has been defined in the board's board.h file. From Dave + Marples (2019-07-28). + * net/udp/udp_txdrain.c: Add missing header file. From David S. Alessio + (2019-07-29). + * sched/semaphore/sem_holder.c: Fix a race in telnet with + PRIORITY_INHERITANCE and SCHED_HPWORK. Sometimes causes an assertion + to fire incorrectly. From David S. Alessio (2019-07-29). + * include/netinet/in.h: Rename __pad member to sin_zero in struct + sockaddr_in. Libwebsockets initializes the 'sin_zero' member of + sockaddr_in objects to zeros. Apparently, judging from mailing list + entries, there are platforms on which not doing this causes undefined + behavior. On NuttX compiling respective code is broken, as the + corresponding member variable is called '__pad'. Neither in the + 'nuttx' nor in the 'apps' repository did I find any reference to this + identifier. Thus, I believe its a safe bet to just rename it. UNIX + Network Programming states in this regard: "The POSIX specification + requires only three members in the structure: sin_family, sin_addr, and + sin_port. It is acceptable for a POSIX-compliant implementation to + define additional structure members, and this is normal for an Internet + socket address structure. Almost all implementations add the sin_zero + member so that all socket address structures are at least 16 bytes in + size." From Michael Jung (2019-07-29). + * arch/arm/src/tiva: Rename TM4C123GH6PMI identifiers to TM4C123GH6PM. + Rationale: In terms of firmware programming, there is no functional + difference between these parts: TM4C123GH6PMI7, TM4C123GH6PMI7R, + TM4C123GH6PMT7, and TM4C123GH6PMT7R. From a programming standpoint, + all of the above parts are TM4C123GH6PM, which means it doesn't make + sense to differentiate between PM and PMI. (The PM means 64-LQFP. The I + means temperature range -40C to +85C. It could be T meaning -40C to + +105C. The R means it ships in Tape and Reel packaging as opposed to + Tray.) From Nathan Hartman (2019-07-29). + * Only use PCLKSEL0 for ADC on LPC176x family. From jjlange (2019-07-29). + * arch/arm/src/tiva: Rename TM4C1294NC identifiers to TM4C1294NCPDT. + Rationale: TM4C1294NC is ambiguous: TM4C1294NCPDT is a 128-TQFP, + TM4C1294NCZAD is a 212-NFBGA. The TM4C1294NC part currently supported + by NuttX is the TM4C1294NCPDT used on the TI EK-TM4C1294XL "Connected + LaunchPad" (see configs/tm4c1294-launchpad). To ensure the correct + part is fully specified, this commit updates all TM4C1294NC identifiers + to TM4C1294NCPDT.

From Michael Jung (2019-07-31). + * libs/libc/dirent/: Added alphasort() implementation, scandir() + implementation and DT_* definitions to include/dirent.h.

From Michael Jung (2019-07-31). + * libs/libc/dirent/lib_scandir.c: Do not build in PROTECTED or KERNEL + mode builds. Add FAR to some pointers. Minor comment updates. From + Gregory Nutt (2019-07-31). + * STM32F7: Serial add HW HS on UART 4 & 5 From David Sidrane + (2019-08-01). + * sched/task/task_exithook.c: nxtask_signalparent() in task_exithook.c + may invalidate the group's parent task ID (tg_ppid) too soon. The + tg_ppid field is use only to remember the parent tasks ID so that it + can send the SIGCHLD signal to it. So it must stay valid until SIGCHLD + has been sent. In nxtask_signalparent(), it calls nxtask_sigchild() to + send SIGCHLD to the parent, then invalidates tg_ppid. That would be + okay, except that the SIGCHLD is only sent when the last member of the + group terminates. That is incorrect; tg_ppid can be invalidated too + soon and, as a consequence, SIGCHLD would never be sent.

From + Gregory Nutt (2019-08-09). + * This commit removes CONFIG_ARCH_INT_DISABLEALL. In the normal course + of things, interrupts must occasionally be disabled using the + up_irq_save() inline function to prevent contention in use of resources + that may be shared between interrupt level and non-interrupt level + logic. Now the question arises, if we are using BASEPRI to disable + interrupts and have high priority interrupts enabled + (CONFIG_ARCH_HIPRI_INTERRUPT=y), do we disable all interrupts except + SVCall (we cannot disable SVCall interrupts). Or do we only disable + the "normal" interrupts? If we are using the BASEPRI register to + disable interrupts, then the answer is that we must disable ONLY the + "normal interrupts". That is because we cannot disable SVCALL + interrupts and we cannot permit SVCAll interrupts running at a higher + priority than the high priority interrupts (otherwise, they will + introduce jitter in the high priority interrupt response time.) Hence, + if you need to disable the high priority interrupt, you will have to + disable the interrupt either at the peripheral that generates the + interrupt or at the NVIC. Disabling global interrupts via the BASEPRI + register cannot effect high priority interrupts.

From Anthony Merlino (2019-08-10). + * mac802154: Fixes issues with extended address. 1) Extended address + should be read-only. 2) Extended address should be placed in frame in + "reverse-canonical" order. The extended address is a read-only + attribute and thus an attempt to write the extended address should be + denied. Instead, the extended address should really be either set by + the PHY/radio itself, or provided at board bring-up time to the radio + layer. The MAC layer now pulls in the extended address from the radio + any time the MAC is reset. The extended address is also supposed to be + sent in the frame in reverse-canonical order. This is very confusing in + the standard and it wasn't until I realized it was backwards in + Wireshark that I researched this further. Searching online I find + documents from the committee for suggestions/feedback on the future + standard. It isn't in the 2015 standard but a newer version of the + standard will presumably clarify this. It says that the extended + address should be written in reverse-canonical form, meaning the OUI + comes last, not first inside the frame.

From Pavel Pisa (2019-08-13). + * symtab/, tools/: NuttX provides lists of available syscalls and + library functions and tools to process them. The lists can be used to + build symbol table which allows runtime program loading which can reuse + functions already compiled into NuttX system image. List processing, + compilation and linking to the final system image has been possible + only under manual control until now. Provided changes add option + (CONFIG_EXECFUNCS_GENERATE_SYSTEM_SYMTAB) to build complete list of + available functions and syscalls automatically. The symbolic table is + generated in form libsymtab.a which can be reused by application or + directly pull in when "g_symtab" and "g_nsymbols" variables are + requested by EXECFUNCS configuration. I have tried to follow + mechanisms for library compilation in different kernel protection modes + but tested only flat no-MMU build. The basic assumption is that this + library and libraries providing syscall stubs and C-library functions + are available in user-space context and initial application (usually + NSH) registers the symbol table through IOCTL. The table can be reused + then by another applications in their address space as kernel allows. + Simple for flat or protected mode, I am not sure if really support in + MMU mode. It is highly probable that I have made some mistake, + overlooked something, but functionality is optional (should not cause + troubles in any mode if disabled) and main purpose is to lower memory + overhead when more applications are loaded on memory constrained system + which usually use direct kernel calling without protection or address + space separation. If the table should be provided by kernel to + applications then makefiles has to be adjusted. From Pavel Pisa + (2019-08-13). + * symtab/Makefile: The OS symbol table should not be generated in the + PROTECTED and KERNEL build modes.

From + Gregory Nutt (2019-08-29). + * arch/arm/src/stm32/stm32_adc.c: Add ADC calibration procedure for + IP_ADC_V1. Tested on STM32F100, and it magically increased result + accuracy. STM32F103 has the same calibration procedure. I am not + sure about others. From Matous Pokorny (2019-08-29). + * net/inet and net/tcp: Fix tcp close flow; free the connection after + all tcp close process finished. From zhangyuan7 (2019-08-30). + * tools/Makefile.* and tools/mkexport.sh: This change allows to export + builtin applications registry into temporarily created directory where + export archive content is prepared. If the Makefile in apps directory + does not define export: target then error is print but export + continues without interruption. It would be more logical to print + warning but there is no way instruct apps make to not print error. + From Pavel Pisa (2019-08-30). + * boards/arm/lpc17xx_40xx/lx_cpu: Add support for the PIKRON LX_CPU + board. From Pavel Pisa (2019-08-30). + * board/Kconfig and board/README.txt: Add configuration support for the + LX_CPU board. From Gregory Nutt (2019-08-30). + * README.txt and Documentation/README.html: Update README file + references to include the LX_CPU board README file. From Gregory Nutt + (2019-08-30). + * boards/arm/lpc17xx_40xx/lx_cpu/src/lpc17_40_ulan.c: Provides for + separate, non-standard, PiKRON uLAN registration at build-/run-time. + From Pavel Pisa (2019-08-30). + * Tiva directories: Fix TM4C129XNCZAD part number in Kconfig and + identifiers. Rationale: Fully specify that this is the 212-pin BGA + package (ZAD ending) and for consistency with earlier changes to other + Tiva TM4C12x part numbers in Kconfig names and identifiers. From + Nathan Hartman (2019-08-30). + * tools/Makefile.win: Port changes of commit + 3ed844640d25b854457b6cc08f89d907072c0054 to Makefile.win. Untested + because I don't have a Windows native build platform setup. There + have been a lot of changes to the build system lately do to directory + re-organization so likely the native build is broken. Certainly + tools/configure.bat should be replaces with tools/configure.c. From + Gregory Nutt (2019-08-30). + * net/Kconfig: Ethernet packet buffer size cannot be permitted to go + below 1294 if IPv6 is selected. From Gregory Nutt (2019-08-31). + * net/: Now handles reception of IPv4 packets with larger IPv4 headers + containing options. From Gregory Nutt (2019-08-31). + * boards/arm/lpc17xx_40xx/lx_cpu/configs/nsh/defconfig: Correct shit + defconfig file. Recent patch dumped a prohibited .config file as the + defconfig file when a proper defconfig file created via 'make + savdefconfig' is required. Bad. From Gregory Nutt (2019-08-31). + * arch/arm/src/stm32/stm32_adc.c: Correct an error found in build + testing. Recent commit to add STM32F1 calibration was not properly + conditioned. Caused compilation errors on all STM32 F2 family + members. From Gregory Nutt (2019-08-31). + * arch/arm/src/stm32/stm32_adc.c: Another fix. adc_calibrate() was + called even when it was conditioned out, causing a link time failure. + From Gregory Nutt (2019-08-31). + * net/: Re-order the content of all address-family socket 'connection' + structures so that they begin with a common prologue. This permits + better use of logic for different address family types. From Gregory + Nutt (2019-09-01). + * net/local/local_conn.c: Removed unnecessary memset(). Connection + structure is allocated with kmm_zalloc() which will clear all memory. + From Gregory Nutt (2019-09-01). + * boards/Board.mk: Add support to pass dependency paths. + boards/arm/cxd56xx/common/Makefile: Add correct dependency paths for + board/ and src/ subdirectories. From Gregory Nutt (2019-09-01). + * net/arp/arp.h: Remove an unused structure definition. From Gregory + Nutt (2019-09-01). + * gs2200m supports SIOCGIFHWADDR From Masayuki Ishikawa (2019-09-02). + * drivers/timers/pwm.c: Move the pwm/pwm.c driver to timers/pwm.c, The + drivers/pwm contained only one .c file (pwm.c), so to avoid the + proliferation of sub-directories inside drivers/ is better to move the + pwm.c driver to drivers/timers. The pwm.h header was moved to + include/nuttx/timers to keep consistency, so all files referencing it + need to be updated. From Augusto Fraga Giachero (2019-09-02). + * libc/libc/unistd/: Add stubs for geteuid(), getegid(), seteuid(), and + setegid(). NuttX does not currently support effective user/group IDs, + but these stubs will support linkage of applications that expect these + POSIX standard interfaces. From Gregory Nutt (2019-09-03). + * libc/libc/unistd/: Add stubs for setreuid(), and setregid(). NuttX + does not currently support effective user/group IDs, but these stubs + will support linkage of applications that expect these POSIX standard + interfaces. From Gregory Nutt (2019-09-03). + * arch/arm/src/arm/up_fullcontextrestore.S: When performing stability + test, the application would cause kernel crash. When I trace the + stack, I find that register R1 has been changed, and its value is the + same as register CPSR. In up_fullcontextrestore.S, the restoration of + R0 and R1 is not atomic: 'msr cpsr r1 will enable interrupts and the + recovery of r0 and r1 may be interrupted and the value or R1 may be + changed. Fix is to use a single ldmia to restore R0, R1, and return + via R15. From Loyen Wang (2019-09-04). + * drivers/sensors/isl29023.c: Add basic driver of ISL29023 ambient + light sensor. The basic driver can set operational mode, range, and + resolution. It can also read lux value in continuous mode. Interrupt + and the alarm is not implemented. From Matous Pokorny (2019-09-04). + * Makefile updates From jjlange (2019-09-05). + * tools/Makefile.win: Change of + 8883623d07f642e205109389268e97b2a519a77a needs to be applied to + Makefile.win too. From Gregory Nutt (2019-09-04). + * Fix some typos. Also minor update to stm32f7/nucleo-144/README.txt and + stm32l4/nucleo-l496zg/README.txt board documentation. From Juha + Niskanen (2019-09-05). + * drivers/rf/dat-31r5-sp.c: Add support to the DAT-31R5-SP+ digital + attenuator. Creates a the new device driver directory drivers/rf/ to + support drivers related to RF peripherals. It also adds support for + the DAT-31R5-SP+ digital attenuator. From Augusto Fraga Giachero + (2019-09-05). + * include/nuttx/spi/spi_bitbang.c: Fix build error when the spi bitbang + variable width support is enabled. From Augusto Fraga Giachero + (2019-09-05). + * include/sys/boardctl.h: Fix numbering of board IOCTL commands. Error + in numbering noted by Nathan Hartman. From Gregory Nutt (2019-09-05). + * net/tcp/tcp_send.c: Commit a52ceac13ee598696cb907b62326bfd4c111ac6c + broke IPv4 sending. In cp_send.c:tcp_ipv4_sendcomplete(), ‘ipv4->vhl’ + now needs to be configured before call to tcp_ipv4_chksum(). Noted by + Jussi Kivilinna in commit comments. From Gregory Nutt (2019-09-06). + * boards/Kconfig: Fix help text for BOARDCTL_IOCTL. From Nathan + Hartman (2019-09-06). + * net/ipforward/ipv4_forward.c: Correct some errors introduced with + commit a52ceac13ee598696cb907b62326bfd4c111ac6c. Noted by Adam + Porter. From Gregory Nutt (2019-09-06). + * tools/Makefile.unix: Rethink creation of new .version file with GIT + information. Cannot use 'sed -i' in its current form because that + does not work on macOS, FreeBSD, or NetBSD. From Gregory Nutt + (2019-09-07). + * tools/version.h and Makefile.unix: Minor improvement to previous + commit: Permit custom version strings that do not derive from the + major and minor version number From Gregory Nutt (2019-09-07). + * arch/arm/src/stm32/stm32_otg[fs|hs]host.c: STM32 host only initiates + transfer if buflenl > 0. From Adam Porter (2019-09-08). + * STM32F7/H7/L4 OTG host: Adam Porter's fix for STM32 FS/HS probably + should be applied to STM32 F7, H7, and L4 OTG host which are very + similar. From Gregory Nutt (2019-09-08). + * EFM32 OTG host: Adam Porter's fix for STM32 FS/HS probably should be + applied to EFM32 host which which has very similar IP. From Gregory + Nutt (2019-09-08). + * arch/arm/src/armv7-a: Fix typo and missing quotation for armv7-a. + From Oki Minabe (2019-09-08). + * arch/arm/src/armv7-a/arm_addrenv_utils.c: Fix double increment in + armv7-a's arm_addrenv_destroy_region(). From Oki Minabe (2019-09-08). + * arch/arm/src/armv7-a/arm_pgalloc.c: Fix L2 page table mask for + armv7-a. From Oki Minabe (2019-09-08). + * drivers/ioexpander/gpio_lower_half.c: Remove limitation when pintype + > GPIO_INTERRUPT_PIN. From ligd (2019-09-09). + * STM32, STM32F7, STM32H7, STM32L4, and EFM32 USB Host: This change was + required to get my devices (CDC-MBIM) to enumerate. Initially the + system timed out retrieving the USB configuration descriptor. Ctrl IN + requests got nothing but NAKs. I found that the initial SETUP packet + and corresponding IN transfer were fine; it was the Status OUT phase + that was getting the NAK. After receiving a NAK on the Status OUT, + the code would loop back and issue another ctrl IN, which will always + fail because the data was already transferred before. Thus the entire + transfer would 'timeout'. The fix I implemented moves the DATANAK + timeout loop to only apply to the Status OUT. Of course this worked + for my devices, but maybe isn't the right solution in general. I + think that both the ctrl IN and the Status OUT need their own retry + loops? From Adam Porter (2019-09-09). + * tools/mkexport.sh: Export LDSCRIPT and STRIP definition and align + with Makefile.export. From Pavel Pisa (2019-09-10). + * boards/arm/lpc17xx_40xx/lx_cpu/configs/nsh/defconfig: Tested + ETHRENET, UARTs, heap in external SDRAM, use of symbol tables for + applications loading over TFTP and kernel modules insertion. USB and + SD card enabled but there are some issues (probably config or IO + ports) still. From Pavel Pisa (2019-09-10). + * sched/sched_rrgetinterval.c: sched_get_rr_interval() should return + {0,0} if round-robin scheduling is not selected for the task. From + Gregory Nutt (2019-09-10). + * include/sys/types.h: Remove non-standard HP-UX priority range + definitions. HP-UX is not a supported OS. From Gregory Nutt + (2019-09-10). + * Fix typos, 1 in a #define, others in comments. This changes one + definition: _MQ_TIMEDRECIEVE is changed to _MQ_TIMEDRECEIVE. It + appears this symbol is not used anywhere. From Nathan Hartman + (2019-09-11). + * boards/z80: Correct path to linker script in all boards using the + ZDS-II toolchain. Yet more fallout from the big boards/ directory + re-organization. From Gregory Nutt (2019-09-11). + * boards/: Several more fixes to Make.defs files and README.txt files. + More collateral damage from the big boargs/ directory + re-organization. From Gregory Nutt (2019-09-11). + * boards/arm/imx6/sabre-6quad/scripts/Make.defs: Yet another boards/ + re-organization fix-up. From Gregory Nutt (2019-09-11). + * libs/libc/builtin/: builtin_isavail() should not set the errno + variable because this functions may be used by internal OS logic for + which setting the errno variable would be inappropriate. From Gregory + Nutt (2019-09-11). + * boards/arm/stm32f0l0g0/nucleo-g071rb/scripts/ld.script: Fix + .ARM.exidx section overlap with .data From Daniel Pereira Volpato + (2019-09-11). + * Modify all files from 2eb4fe5ffb7dee21b33 to use solution from Daniel + P. Volpato. From Alan Carvalho de Assis (2019-09-11). + * Modify all a few more linker scripts missed in 415e3d34482012ab308, + probably because they were created after 2eb4fe5ffb7dee21b33. From + Gregory Nutt (2019-09-11). + * Move EXIDX-related assignments inside of braces so that we can be + assure that the symbols have the correct alignment. Suggested by + Daniel P. Volpato From Gregory Nutt (2019-09-12). + * boards/arm/tiva/tm4c123g-launchpad/scripts/tm4c123g-launchpad.ld: Add + alignments for the TMC4123G-LaunchPad as well. From Nathan Hartman + (2019-09-12). + * boards/arm/stm32/axoloti, omnibusf4, and stm32f4discovery: If + CONFIG_SCHED_CRITMONITOR is selected, then make sure that ITM and DWT + resources are enabled before accessing ITM and DWT registers.

Some changes to comments. From Juha Niskanen (2019-09-16). + * Large Ethernet packet can leads network halt From Bazooka Joe + (2019-09-16). + * boards/mips Linker Scripts: The PIC32M* start-up code initializes + .bss by writing 16 bytes at a time in a loop. The start (_sbss) + alignment is only required to be 4 bytes since the write is done with + 4 store instructions. In a previous change, the end address, _ebss, + was aligned to 16 byte to prevent initializing past the end off the + .bss region. However, that does not work unless the start address, + _sbss, is also aligned to 16 bytes.

From + Matias N (2019-11-08). + * This change, initially for the imxrt1050, separates out the pinmux and + iomux functions cleanly. For ease of conversion default IOMUX + definitions have been added into imxrt_iomux.h. The change effectively + does two things; + (1) Unifies the iomux definitions - previously some pins had them, and + some didn't. This effectively made it impossible to use the + pinmuxes without editing the header file in the standard + distribution tree. + (2) Unifies the pin definitions so that every pin now has a suffix. + This makes it *much* easier to see when a pin is in use in your + code, because it will always have a definition in your board.h file. + For anyone who is already using this CPU, a couple of small changes + are needed to existing code; + - In respect of (1) add IOMUX decorators to your pin definitions. + You will find defaults in haardware/imxrt_iomux.h. Every pin + should have a IOMUX decorator and in general the defaults should + be OK. + - In respect of (2) you will need to add selectors for any function + that previously only had one pinning option.

TC (Transmission complete) and TDRE (TX Buffer + Empty) were transposed in imxrt_serial.c. The end result was that + for unoptimised code everything worked fine, but optimised code + got itself into a real mess and continually fired interrupts. The + change attached fixes this. This one would have been found much + more quickly if this particular board had supported SWO :-/ + 2) Startup issue. There are a number of chip errata that apply to + the 1052 first revision (A-suffix) that don't apply to the second + (B-suffix). Those got me for a while and it's important to use an + EVK_B_ dev board if you're suffering stability problems with this + particular chip. However, even with that resolved with either + optimised or unoptimised code when there is no SNVS (Battery + Backup) power and the power is switched on the CPU appears to boot + but gets stuck with timer interrupts not being generated. The CPU + is running and it will execute linear code. I have determined + this by putting an 'imxrt_lowputc('A'+irq)' into up_doirq. For the + non-running case the output looks like this: + + LLLL + + this implies 4 0x0b interrupts have been generated, and nothing + else. If I hit keys on the keyboard I get 'e' in the flow. 0x0b + is the SVC instruction and is the mechanism by which NuttX handles + task switching. 'e' is 0x24, which corresponds to the LPUART1 + interrupt. Other than these, the system does not respond further + but is happily in the idle loop. In this circumstance if you hit + SW2 on the EVKB board though the logjam 'unjams' and normal + service is established, output now looks like: + + LLLLPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPLPP ...etc. + + Where 'P' is 0x0f (the SYSTICK interrupt)....this is what _should_ + be happening so; SYSTICK starts up after SW2 has been pressed. + From this point on everything works correctly and you can reboot + the CPU, put new code into it or do whatever you wish, **provided + power is not cycled off**. If power is cycled off then return to + the top and go through the process again. When there is SNVS + power to the CPU then power can be switched on and off as you + wish, and the CPU will boot correctly. This has been determined by + putting 3V onto J6. + I think we are probably doing something naughty with the way we + are starting the clocks to the timers.

NuttX may also be installed and built on Windows system + if you also provide such a POSIX development environment. Options for a + POSIX development environment under Windows include: + + - An installation of Linux on a virtual machine (VM) in Windows. I have + not been happy using a VM myself. I have had stability problems with + open source VMs and commercial VMs cost more than I want to spend. + Sharing files with Linux running in a VM is awkward; sharing devices + connected to the Windows box with Linux in a VM is, at the very least, + confusing; Using Windows tools (such as Segger J-Link) with files + built under the Linux VM is not a possibility. + + - The Cygwin environment. Instructions for installation of Cygwin on a + Windows system are provided in the following paragraph, "Installing + Cygwin". Cygwin is a mature, well-tested, and very convenient + environment. It is especially convenient if you need to + integrate with Windows tools and files. Downsides are that the + installation time is very long and the compile times are slow. + + - Ubuntu/Bash shell under Windows 10. This is a new option under + Windows 10. See the section "Ubuntu Bash under Windows 10" below. + This is an improvement over Cygwin if your concern is compile time; + its build performance is comparable to native Linux, certainly better + than the Cygwin build time. It also installs in a tiny fraction of + the time as Cygwin, perhaps 20 minutes for the basic Ubuntu install + (vs. more than a day for the complete Cygwin install). + + There have been even more recent ports of Linux environment to + Windows. I need to update this section to include some mention of + these alternatives. + + - The MSYS environment. MSYS derives from an older version of Cygwin + simplified and adapted to work more naturally in the Windows + environment. See http://www.mingw.org/wiki/MSYS if you are + interested in using MSYS. The advantages of the MSYS environment is + that it is better integrted with the native Windows environment and + lighter weight; it uses only a minimal number of add-on POSIX-land + tools. + + The download link in that Wiki takes you to the SourceForge download + site. The SourceForge MSYS project has been stagnant for some time. + The MSYS project has more recently moved to + http://odsn.net/projects/sfnet_mingwbundle. Downloads of current .zip + files are available there but no instructions for the installation. + + - MSYS2 appears to be a re-write of MSYS based on a newer version of + Cygwin. Is it available at https://www.msys2.org. A windows + installer is available at that site along with very good installation + instructions. The download is relatively quick (at least compared to + Cygwin) and the 'pacman' package management tool supports supports + simple system updates. For example, 'pacman -S git' will install the + GIT command line utilities. + + - Other POSIX environments. Check out: + + UnxUtils: https://sourceforge.net/projects/unxutils/, + https://en.wikipedia.org/wiki/UnxUtils + MobaXterm: https://mobaxterm.mobatek.net/ + Gow: https://github.com/bmatzelle/gow/wiki + + Disclaimer: In principle, these should work. However, I have never + used any of these environments and cannot guarantee that there is + not some less-than-obvious issues. + + NuttX can also be installed and built on a native Windows system, but with + some potential tool-related issues (see the discussion "Native Windows + Build" under "Building NuttX" below). GNUWin32 is used to provide + compatible native windows tools. + +Installing Cygwin +----------------- + + Installing Cygwin on your Windows PC is simple, but time consuming. See + http://www.cygwin.com/ for installation instructions. Basically you just + need to download a tiny setup.exe program and it does the real, network + installation for you. + + Some Cygwin installation tips: + + 1. Install at C:\cygwin + + 2. Install EVERYTHING: "Only the minimal base packages from the + Cygwin distribution are installed by default. Clicking on categories + and packages in the setup.exe package installation screen will + provide you with the ability to control what is installed or updated. + Clicking on the "Default" field next to the "All" category will + provide you with the opportunity to install every Cygwin package. + Be advised that this will download and install hundreds of megabytes + to your computer." + + If you use the "default" installation, you will be missing many + of the Cygwin utilities that you will need to build NuttX. The + build will fail in numerous places because of missing packages. + + NOTE: The last time I installed EVERYTHING, the download was + about 5GiB. The server I selected was also very slow so it took + over a day to do the whole install! + + NOTE: You don't really have to install EVERYTHING but I cannot + answer the question "Then what should I install?" I don't know + the answer to that and so will continue to recommend installing + EVERYTHING. + + You should certainly be able to omit "Science", "Math", and + "Publishing". You can try omitting KDE, Gnome, GTK, and other + graphics packages if you don't plan to use them. + + Perhaps a minimum set would be those packages listed below for the + "Ubuntu Bash under Windows 10" installation? + + UPDATE: Sergey Frolov had success with the following minimal + Cygwin configuration: + + 1. After starting the Cygwin installer, keep the recommended + packages that are pre-selected in the default configuration. + 2. Using the installation tools, add the following packages: + + make (GNU make) bison libgmp3-dev + gcc-core byacc libmpfr-dev + gcc-g++ gperf libmpc-dev + flex gdb automake-1.15 + libncurses-dev libgmp-dev + + After installing Cygwin, you will get lots of links for installed + tools and shells. I use the RXVT native shell. It is fast and reliable + and does not require you to run the Cygwin X server (which is neither + fast nor reliable). Unless otherwise noted, the rest of these + instructions assume that you are at a bash command line prompt in + either Linux or in Cygwin shell. + +Using MSYS +---------- + + MSYS is an environment the derives from Cygwin. Thus, most things said + about Cygwin apply equally to MSYS. This section will, then, focus on + the differences when using MSYS, specifically MSYS2. + + Here is it assumed that you have already downloaded and installed MSYS2 + from https://www.msys2.org using the windows installer available at that + location. It is also assumed that you have brought in the necessary + tools using the 'pacman' package management tool Tools needed including: + + pacman -S git + pacman -S make + pacman -S gcc + pacman -S gdb + + And possibly others depending upon your usage. Then you will need to + build and install kconfig-frontends per the instructions of the top-level + README.txt file in the tools repository. This requires the following + additional tools: + + pacman -S bison + pacman -S gperf + pacman -S ncurses-devel + pacman -S automake-wrapper + pacman -S autoconf + pacman -S pkg-config + + Because of some versioning issues, I had to run 'aclocal' prior to + running the kconfig-frontends configure script. See "Configuring NuttX" + below for further information. + + Unlike Cygwin, MSYS does not support symbolic links. The 'ln -s' command + will, in fact, copy a directory! This means that you Make.defs file will + have to include definitions like: + + ifeq ($(CONFIG_WINDOWS_MSYS),y) + DIRLINK = $(TOPDIR)/tools/copydir.sh + DIRUNLINK = $(TOPDIR)/tools/unlink.sh + endif + + This will force the directory copies to work in a way that can be handled + by the NuttX build system. NOTE: The default link.sh script has been + updated so that is should now be MSYS2 compatible. The above is preferred + but no longer necessary in the Make.defs file. + + To build the simulator under MSYS, you also need: + + pacman -S zlib-devel + + It appears that you cannot use directory names with spaces in them like + "/c/Program\ Files \(86\)" in the MSYS path variable. I worked around this + by create Windows junctions like this:: + + 1. Open the a windows command terminal, + 2. CD to c:\msys64, then + 3. mklink /j programfiles "C:/Program\ Files" and + 4. mklink /j programfiles86 "C:/Program\ Files\ \(x86\)" + + They then show up as /programfiles and /programfiles86 with the MSYS2 + sandbox. Thos paths can then be used with the PATH variable. I had + to do something similar for the path to the GNU Tools "ARM Embedded + Toolchain" which also has spaces in the path name. + +Ubuntu Bash under Windows 10 +---------------------------- + + A better version of a command-line only Ubuntu under Windows 10 (beta) + has recently been made available from Microsoft. + + Installation + ------------ + Installation instructions abound on the Internet complete with screen + shots. I will attempt to duplicate those instructions in full here. + Here are the simplified installation steps: + + - Open "Settings". + - Click on "Update & security". + - Click on "For Developers". + - Under "Use developer features", select the "Developer mode" option to + setup the environment to install Bash. + - A message box should pop up. Click "Yes" to turn on developer mode. + - After the necessary components install, you'll need to restart your + computer. + + Once your computer reboots: + + - Open "Control Panel". + - Click on "Programs". + - Click on "Turn Windows features on or off". + - A list of features will pop up, check the "Windows Subsystem for Linux + (beta)" option. + - Click OK. + - Once the components installed on your computer, click the "Restart + now" button to complete the task. + + After your computer restarts, you will notice that Bash will not appear in + the "Recently added" list of apps, this is because Bash isn't actually + installed yet. Now that you have setup the necessary components, use the + following steps to complete the installation of Bash: + + - Open "Start", do a search for bash.exe, and press "Enter". + - On the command prompt, type y and press Enter to download and install + Bash from the Windows Store. This will take awhile. + - Then you'll need to create a default UNIX user account. This account + doesn't have to be the same as your Windows account. Enter the + username in the required field and press Enter (you can't use the + username "admin"). + - Close the "bash.exe" command prompt. + + Now that you completed the installation and setup, you can open the Bash + tool from the Start menu like you would with any other app. + + Accessing Windows Files from Ubuntu + ----------------------------------- + File systems will be mounted under "/mnt" so for example "C:\Program Files" + appears at "/mnt/c/Program Files". This is as opposed to Cygwin where + the same directory would appear at "/cygdrive/c/Program Files". + + With these differences (perhaps a few other Windows quirks) the Ubuntu + install works just like Ubuntu running natively on your PC. + + A good tip for file sharing is to use symbolic links within your Ubuntu + home directory. For example, suppose you have your "projects" directory + at C:\Documents\projects. Then you can set up a link to the projects/ + directory in your Ubuntu directory like: + + ln -s /mnt/c/Documents/projects projects + + Accessing Ubuntu Files From Windows + ----------------------------------- + In Ubuntu Userspace for Windows, the Ubuntu file system root directory is + at: + + %localappdata%\lxss\rootfs + + Or + + C:\Users\Username\AppData\Local\lxss\rootfs + + However, I am unable to see my files under the rootfs\home directory. + After some looking around, I find the home directory + %localappdata%\lxss\home. + + With that trick access to the /home directory, you should actually be + able to use Windows tools outside of the Ubuntu sandbox with versions of + NuttX built within the sandbox using that path. + + Executing Windows Tools from Ubuntu + ----------------------------------- + You can also execute Windows tools from within the Ubuntu sandbox: + + /mnt/c/Program\ Files\ \(x86\)/Microchip/xc32/v1.43/bin/xc32-gcc.exe --version + Unable to translate current working directory. Using C:\WINDOWS\System32 + xc32-gcc.exe (Microchip Technology) 4.8.3 MPLAB XC32 Compiler v1.43 Build date: Mar 1 2017 + ... + + The error message indicates that there are more issues: You cannot mix + Windows tools that use Windows style paths in an environment that uses + POSIX paths. I think you would have to use Linux tools only from within + the Ubuntu sandbox. + + Install Ubuntu Software + ----------------------- + Use "sudo apt-get install ". As examples, this is how + you would get GIT: + + sudo apt-get install git + + This will get you a compiler for your host PC: + + sudo apt-get install gcc + + This will get you an ARM compiler for your target: + + sudo apt-get install gcc-arm-none-eabi + + NOTE: That is just an example. I am not sure if apt-get will give you a + current or usable compiler. You should carefully select your toolchain + for the needs of your project. + + You will also need to get the kconfig-frontends configuration as + described below under "NuttX Configuration Tool". In order to build the + kconfig-frontends configuration tool you will also need: make, gperf, + flex, bison, and libncurses-dev. + + That is enough to do a basic NuttX build. + + Integrating with Windows Tools + ------------------------------ + If you want to integrate with Windows native tools, then you would need + deal with the same kind of craziness as with integrating Cygwin with + native toolchains, see the section "Cygwin Build Problems" below. + + However, there is currently no build support for using Windows native + tools with Ubuntu under Windows. This tool combination is made to work + with Cygwin through the use of the 'cygpath -w' tool that converts paths + from say '/cydrive/c/Program Files' to 'C:\Program Files'. There is, + however, no corresponding tool to convert '/mnt/c/Program Files' in the + Ubuntu environment. + + Graphics Support + ---------------- + The Ubuntu version support by Microsoft is a command-line only version. + There is no support for Linux graphics utilities. + + This limitation is not a limitation of Ubuntu, however, only in what + Microsoft is willing to support. If you install a X-Server, then you + can also use basic graphics utilities. See for example: + + http://www.howtogeek.com/261575/how-to-run-graphical-linux-desktop-applications-from-windows-10s-bash-shell/ + + Many Linux graphics programs would, however, also require a graphics + framework like GTK or Qt. So this might be a trip down the rabbit hole. + +INSTALLATION +^^^^^^^^^^^^ + + There are two ways to get NuttX: You may download released, stable + tarballs from either the Bitbucket or Sourceforge download locations. + Or you may get NuttX by cloning the Bitbucket GIT repositories. Let's + consider the released tarballs first: + +Download and Unpack +------------------- + + Download and unpack the NuttX tarball. If you are reading this, then + you have probably already done that. After unpacking, you will end + up with a directory called nuttx-version (where version is the NuttX + version number). You might want to rename that directory nuttx to + match the various instructions in the documentation and some scripts + in the source tree. + + Download locations: + + https://bitbucket.org/nuttx/nuttx/downloads + https://sourceforge.net/projects/nuttx/files/nuttx/ + +Semi-Optional apps/ Package +--------------------------- + + All NuttX libraries and example code used to be in included within + the NuttX source tree. As of NuttX-6.0, this application code was + moved into a separate tarball, the apps tarball. If you are just + beginning with NuttX, then you will want to download the versioned + apps tarball along with the NuttX tarball. If you already have your + own product application directory, then you may not need the apps + tarball. + + It is called "Semi-optional" because if you don't have some apps/ + directory, NuttX will *fail* to build! You do not necessarily need + to use the NuttX apps tarball but may, instead, provide your own + custom application directory. Such a custom directory would need + to include a valid Makefile to support the build and a valid Kconfig + file to support the configuration. More about these files later. + + Download then unpack the apps tarball in the same directory where you + unpacked the NuttX tarball. After you unpack the apps tarball, you + will have a new directory called apps-version (where the version + should exactly match the version of the NuttX tarball). Again, you + might want to rename the directory to simply apps/ to match what + you read in the documentation + + After unpacking (and renaming) the apps tarball, you will have two + directories side by side like this: + + | + +----+----+ + | | + nuttx/ apps/ + + This is important because the NuttX build will expect to find the + apps directory in that (default) location. That default location + can be changed by modifying your NuttX configuration file, but that + is another story. + +Installation Directories with Spaces in the Path +------------------------------------------------ + + The nuttx build directory should reside in a path that contains no + spaces in any higher level directory name. For example, under + Cygwin, your home directory might be formed from your first and last + names like: "/home/First Last". That will cause strange errors when + the make system tries to build. + + [Actually, that problem is probably not too difficult to fix. Some + Makefiles probably just need some paths within double quotes] + + I work around spaces in the home directory name, by creating a + new directory that does not contain any spaces, such as /home/nuttx. + Then I install NuttX in /home/nuttx and always build from + /home/nuttx/nuttx-code. + +Downloading from Repositories +----------------------------- + + Cloning the Repository + + BEFORE cloning repositories on any Windows platform do the following GIT + command: + + git config --global core.autocrlf false + + That will avoid conversions of linefeeds (newlines, \n) to carriage + return plus linefeed sequences (\r\n) + + The current NuttX du jour is available in from a GIT repository. Here are + instructions for cloning the core NuttX RTOS (corresponding to the nuttx + tarball discussed above):: + + git clone https://bitbucket.org/nuttx/nuttx.git nuttx + + And the semi-optional apps/ application directory and be cloned like: + + git clone https://bitbucket.org/nuttx/apps.git apps + + That will give you the same directory structure like this: + + | + +----+----+ + | | + nuttx/ apps/ + + Configuring the Clones + + The following steps need to be performed for each of the repositories. + After changing to the clone directory: + + Set your identity: + + git config --global user.name "My Name" + git config --global user.email my.name@example.com + + Colorized diffs are much easier to read: + + git config --global color.branch auto + git config --global color.diff auto + git config --global color.interactive auto + git config --global color.status auto + + Checkout other settings + + git config --list + + Cloning NuttX Inside Cygwin + + If you are cloning the NuttX repository, it is recommended to avoid + automatic end of lines conversions by git. These conversions may break + some scripts like configure.sh. Before cloning, do the following: + + git config --global core.autocrlf false + +Related Repositories +-------------------- + + These are standalone repositories: + + * https://bitbucket.org/nuttx/apps + + This directory holds an optional package of applications and libraries + can be used with the NuttX RTOS. There is a README.txt file there that + will provide more information about that package. + + * https://bitbucket.org/nuttx/nxwidgets + + This is the NuttX C++ graphics support. This includes NxWM, the tiny + NuttX Window Manager. + + * https://bitbucket.org/nuttx/uclibc + + This repository contains a version of the uClibc++ C++ library. This code + originates from http://cxx.uclibc.org/ and has been adapted for NuttX by the + RGMP team (http://rgmp.sourceforge.net/wiki/index.php/Main_Page). + + * https://bitbucket.org/nuttx/buildroot + + A environment that you can to use to build a custom, NuttX GNU toolchain. + + * https://bitbucket.org/nuttx/tools + + There are snapshots of some tools here that you will need to work with + NuttX: kconfig-frontends, genromfs, and others. + + * https://bitbucket.org/nuttx/pascal + + Yes, this really is a Pascal compiler. The Pascal p-code run-time and + pcode debugger can be built as a part of NuttX. + +Notes about Header Files +------------------------ + + Other C-Library Header Files. + + When a GCC toolchain is built, it must be built against a C library. + The compiler together with the contents of the C library completes the + C language definition and provides the complete C development + environment. NuttX provides its own, built-in C library. So the + complete, consistent C language definition for use with NuttX comes from + the combination of the compiler and the header files provided by the + NuttX C library. + + When a GCC toolchain is built, it incorporates the C library header + files into the compiler internal directories and, in this way, the C + library really becomes a part of the toolchain. If you use the NuttX + buildroot toolchain as described below under "NuttX Buildroot + Toolchain", your GCC toolchain will build against the NuttX C library + and will incorporate the NuttX C library header files as part of the + toolchain. + + If you use some other, third-party tool chain, this will not be the + case, however. Those toolchains were probably built against some + other, incompatible C library distribution (such as newlib). Those + tools will have incorporated the incompatible C library header files + as part of the toolchain. These incompatible header files must *not* + be used with NuttX because they will conflict with definitions in the + NuttX built-in C-Library. For such toolchains that include header + files from a foreign C-Library, NuttX must be compiled without using + the standard header files that are distributed with your toolchain. + This prevents including conflicting, incompatible header files such + as stdio.h. + + The math.h and stdarg.h are probably the two most trouble some header + files to deal with. These troublesome header files are discussed in + more detail below. + + Header Files Provided by Your Toolchain. + + Certain header files, such as setjmp.h, stdarg.h, and math.h, may still + be needed from your toolchain and your compiler may not, however, be able + to find these if you compile NuttX without using standard header files + (i.e., with -nostdinc). If that is the case, one solution is to copy + those header file from your toolchain into the NuttX include directory. + + Duplicated Header Files. + + There are also a few header files that can be found in the nuttx/include + directory which are duplicated by the header files from your toolchain. + stdint.h and stdbool.h are examples. If you prefer to use the stdint.h + and stdbool.h header files from your toolchain, those could be copied + into the nuttx/include/ directory. Using most other header files from + your toolchain would probably cause errors. + + math.h + + Even though you should not use a foreign C-Library, you may still need + to use other, external libraries with NuttX. In particular, you may + need to use the math library, libm.a. NuttX supports a generic, built-in + math library that can be enabled using CONFIG_LIBM=y. However, you may + still want to use a higher performance external math library that has + been tuned for your CPU. Sometimes such tuned math libraries are + bundled with your toolchain. + + The math library header file, math.h, is a then special case. If you do + nothing, the standard math.h header file that is provided with your + toolchain will be used. + + If you have a custom, architecture specific math.h header file, then + that header file should be placed at arch//include/math.h. There + is a stub math.h header file located at include/nuttx/lib/math.h. This stub + header file can be used to "redirect" the inclusion to an architecture- + specific math.h header file. If you add an architecture specific math.h + header file then you should also define CONFIG_ARCH_MATH_H=y in your + NuttX Configuration file. If CONFIG_ARCH_MATH_H is selected, then the + top-level Makefile will copy the stub math.h header file from + include/nuttx/lib/math.h to include/math.h where it will become the system + math.h header file. The stub math.h header file does nothing other + than to include that architecture-specific math.h header file as the + system math.h header file. + + float.h + + If you enable the generic, built-in math library, then that math library + will expect your toolchain to provide the standard float.h header file. + The float.h header file defines the properties of your floating point + implementation. It would always be best to use your toolchain's float.h + header file but if none is available, a default float.h header file will + be provided if this option is selected. However, there is no assurance + that the settings in this float.h are actually correct for your platform! + + stdarg.h + + In most cases, the correct version of stdarg.h is the version provided + with your toolchain. However, sometimes there are issues with + using your toolchains stdarg.h. For example, it may attempt to draw in + header files that do not exist in NuttX or perhaps the header files that + it uses are not compatible with the NuttX header files. In those cases, + you can use an architecture-specific stdarg.h header file by defining + CONFIG_ARCH_STDARG_H=y. + + See the discussion above for the math.h header. This setting works + exactly the same for the stdarg.h header file. + +CONFIGURING NUTTX +^^^^^^^^^^^^^^^^^ + +Instantiating "Canned" Configurations +------------------------------------- + + configure.sh and configure.bat: + + "Canned" NuttX configuration files are retained in: + + boards////configs/ + + Where is the name of your development board and + is the name of the sub-directory containing a specific configuration for + that board. and refer to characteristics of the + MCU used on the board: is the CPU architecture implemented + by the MCU; identifies the MCU chip family. Only a few + steps are required to instantiate a NuttX configuration, but to make the + configuration even easier there are scripts available in the tools/ + sub-directory combines those simple steps into one command. + + There is one tool for use with any Bash-like shell that does configuration + steps. It is used as follows: + + tools/configure.sh : + + There is an alternative Windows batch file that can be used in the windows + native environment like: + + tools\configure.bat : + + And, to make sure that other platforms are supported, there is also a + C program at tools/configure.c that can be compiled to establish the + board configuration. + + See tools/README.txt for more information about these scripts. + + General information about configuring NuttX can be found in: + + {TOPDIR}/boards/README.txt + {TOPDIR}/boards////README.txt + + The Hidden Configuration Scripts: + + As mentioned above, there are only a few simple steps to instantiating a + NuttX configuration. Those steps are hidden by the configuration scripts + but are summarized below: + + 1. Copy Files + + Configuring NuttX requires only copying two files from the + to the directory where you installed NuttX (TOPDIR): + + Copy boards////configs//Make.def + to {TOPDIR}/Make.defs + + OR + + Copy boards////scripts/Make.def + to {TOPDIR}/Make.defs + + Make.defs describes the rules needed by your tool chain to compile + and link code. You may need to modify this file to match the + specific needs of your toolchain. NOTE that a configuration may + have its own unique Make.defs file in its configuration directory or + it may use a common Make.defs file for the board in the scripts/ + directory. The first takes precedence. + + Copy boards////configs//defconfig + to{TOPDIR}/.config + + The defconfig file holds the actual build configuration. This + file is included by all other make files to determine what is + included in the build and what is not. This file is also used + to generate a C configuration header at include/nuttx/config.h. + + Copy other, environment-specific files to{TOPDIR} + + This might include files like .gdbinit or IDE configuration files + like .project or .cproject. + + 2. Refresh the Configuration + + New configuration setting may be added or removed. Existing settings + may also change there values or options. This must be handled by + refreshing the configuration as described below. + + NOTE: NuttX uses only compressed defconfig files. For the NuttX + defconfig files, this refreshing step is *NOT* optional; it is also + necessary to uncompress and regenerate the full making file. This is + discussed further below. + +Refreshing Configurations +------------------------- + + Configurations can get out of date. As new configuration settings are + added or removed or as dependencies between configuration settings + change, the contents of a default configuration can become out of synch + with the build systems. Hence, it is a good practice to "refresh" each + configuration after configuring and before making. To refresh the + configuration, use the NuttX Configuration Tool like this: + + make oldconfig + + AFTER you have instantiated the NuttX configuration as described above. + The configuration step copied the .config file into place in the top-level + NuttX directory; 'make oldconfig' step will then operate on that .config + file to bring it up-to-date. + + If your configuration is out of date, you will be prompted by 'make oldconfig' + to resolve the issues detected by the configuration tool, that is, to + provide values for the new configuration options in the build system. Doing + this can save you a lot of problems down the road due to obsolete settings in + the default board configuration file. The NuttX configuration tool is + discussed in more detail in the following paragraph. + + Confused about what the correct value for a new configuration item should + be? Enter ? in response to the 'make oldconfig' prompt and it will show + you the help text that goes with the option. + + If you don't want to make any decisions are willing to just accept the + recommended default value for each new configuration item, an even easier + way is: + + make olddefconfig + + The olddefconfig target will simply bring your configuration up to date with + the current Kconfig files, setting any new options to the default value. + No questions asked. + +NuttX Configuration Tool +------------------------ + + An automated tool has been incorporated to support re-configuration + of NuttX. This tool is based on the kconfig-frontends application available + at https://bitbucket.org/nuttx/tools/src/master/kconfig-frontends/. (This + is a snapshot of http://ymorin.is-a-geek.org/projects/kconfig-frontends.) + This application provides a tool called 'kconfig-mconf' that is used by the + NuttX top-level Makefile. The following make target is provided: + + make menuconfig + + This make target will bring up NuttX configuration menus. + + WARNING: Never do 'make menuconfig' on a configuration that has + not been converted to use the kconfig-frontends tools! This will + damage your configuration (see + http://www.nuttx.org/doku.php?id=wiki:howtos:convertconfig). + + How do we tell a new configuration from an old one? See "Incompatibilities + with Older Configurations" below. + + The 'menuconfig' make target depends on two things: + + 1. The Kconfig configuration data files that appear in almost all + NuttX directories. These data files are the part that is still + under development (patches are welcome!). The Kconfig files + contain configuration information for the configuration settings + relevant to the directory in which the Kconfig file resides. + + NOTE: For a description of the syntax of this configuration file, + see kconfig-language.txt in the tools repository at + https://bitbucket.org/nuttx/tools + + 2. The 'kconfig-mconf' tool. 'kconfig-mconf' is part of the + kconfig-frontends package. You can download that package from the + snapshot in the tools repository at https://bitbucket.org/nuttx/tools. + + Building kconfig-frontends under Linux may be as simple as + 'configure; make; make install' but there may be some build + complexities, especially if you are building under Cygwin. See + the more detailed build instructions in the top-level README.txt + file of the tools repository at https://bitbucket.org/nuttx/tools. + + The 'make install' step will, by default, install the 'kconfig-mconf' + tool at /usr/local/bin/mconf. Where ever you choose to + install 'kconfig-mconf', make certain that your PATH variable includes + a path to that installation directory. + + The kconfig-frontends tools will not build in a native Windows + environment directly "out-of-the-box". For the Windows native + case, you should use the modified version of kconfig-frontends + that can be found at + http://uvc.de/posts/linux-kernel-configuration-tool-mconf-under-windows.html + + The basic configuration order is "bottom-up": + + - Select the build environment, + - Select the processor, + - Select the board, + - Select the supported peripherals + - Configure the device drivers, + - Configure the application options on top of this. + + This is pretty straight forward for creating new configurations + but may be less intuitive for modifying existing configurations. + + Another ncurses-based tool that is an option to kconfig-mconf is + kconfig-nconf. The differences are primary in in the aesthetics of the + UI. If you have kconfig-nconf built, then you can invoke that front end + with: + + make nconfig + + If you have an environment that supports the Qt or GTK graphical systems + (probably KDE or gnome, respectively, or Cygwin under Windows with Qt or + GTK installed), then you can also build the graphical kconfig-frontends, + kconfig-qconf and kconfig-gconf. In these case, you can start the + graphical configurator with either: + + make qconfig + + or + + make gconfig + + Some keyboard shortcuts supported by kconfig-mconf, the tool that runs + when you do 'make menuconfig': + + - '?' will bring up the mconfig help display. + + - '/' can be used find configuration selections. + + - 'Z' can be used to reveal hidden configuration options + + These last two shortcuts are described further in the following + paragraphs. + +Finding Selections in the Configuration Menus +--------------------------------------------- + + The NuttX configuration options have gotten complex and it can be very + difficult to find options in the menu trees if you are not sure where + to look. The "basic configuration order" describe above can help to + narrow things down. + + But if you know exactly what configuration setting you want to select, + say CONFIG_XYZ, but not where to find it, then the 'make menuconfig' + version of the tool offers some help: By pressing the '/' key, the + tool will bring up a menu that will allow you to search for a + configuration item. Just enter the string CONFIG_XYZ and press 'ENTER'. + It will show you not only where to find the configuration item, but + also all of the dependencies related to the configuration item. + +Reveal Hidden Configuration Options +----------------------------------- + + If you type 'Z', then kconfig-mconf will change what is displayed. + Normally, only enabled features that have all of their dependencies met + are displayed. That is, of course, not very useful if you would like to + discover new options or if you are looking for an option and do not + realize that the dependencies have not yet been selected and, hence, it + is not displayed. + + But if you enter 'Z', then every option will be shown, whether or not its + dependencies have been met. You can then see everything that could be + selected with the right dependency selections. These additional options + will be shown the '-' for the selection and for the value (since it + cannot be selected and has no value). About all you do is to select + the option to see what the dependencies are. + +Make Sure that You are on the Right Platform +-------------------------------------------- + + Saved configurations may run on Linux, Cygwin (32- or 64-bit), or other + platforms. The platform characteristics can be changed use 'make + menuconfig'. Sometimes this can be confusing due to the differences + between the platforms. Enter sethost.sh + + sethost.sh is a simple script that changes a configuration to your + host platform. This can greatly simplify life if you use many different + configurations. For example, if you are running on Linux and you + configure like this: + + tools/configure.sh board:configuration + + The you can use the following command to both (1) make sure that the + configuration is up to date, AND (2) the configuration is set up + correctly for Linux: + + tools/sethost.sh -l + + Or, if you are on a Windows/Cygwin 64-bit platform: + + tools/sethost.sh -c + + Or, for MSYS/MSYS2: + + tools/sethost.sh -g + + Other options are available from the help option built into the + script. You can see all options with: + + tools/sethost.sh -h + + Recently, the options to the configure.sh (and configure.bat) scripts have + been extended so that you both setup the configuration, select for the host + platform that you use, and uncompress and refresh the defconfig file all in + one command like: + + tools/configure.sh -l board:configuration + + For a Linux host or for a Windows/Cygwin host: + + tools/configure.sh -h board:configuration + + Other options are available from the help option built into the + script. You can see all options with: + + tools/configure.sh -h + +Comparing Two Configurations +---------------------------- + + If you try to compare two configurations using 'diff', you will probably + not be happy with the result. There are superfluous things added to + the configuration files that make comparisons with the human eye + difficult. + + There is a tool at nuttx/tools/cmpconfig.c that can be built to simplify + these comparisons. The output from this difference tool will show only + the meaningful differences between two configuration files. This tool is + built as follows: + + cd nuttx/tools + make -f Makefile.host + + This will create a program called 'cmpconfig' or 'comconfig.exe' on Windows. + + Why would you want to compare two configuration files? Here are a few + of the reasons why I do this + + 1. When I create a new configuration I usually base it on an older + configuration and I want to know, "What are the options that I need to + change to add the new feature to the older configurations?" For example, + suppose that I have a boardA/nsh configuration and I want to create a + boardA/nxwm configuration. Suppose I already have boardB/nsh and + boardB/nxwm configurations. Then by comparing the boardB/nsh with the + boardB/nxwm I can see the modifications that I would need to make to my + boardA/nsh to create a new boardA/nxwm. + + 2. But the most common reason that I use the 'cmpconfig' program is to + check the results of "refreshing" a configuration with 'make oldconfig' + (see the paragraph "Refreshing Configurations" above). The 'make + oldconfig' command will make changes to my configuration and using + 'cmpconfig', I can see precisely what those changes were and if any + should be of concern to me. + + 3. The 'cmpconfig' tool can also be useful when converting older, legacy + manual configurations to the current configurations based on the + kconfig-frontends tools. See the following paragraph. + +Making defconfig Files +---------------------- + + .config Files as defconfig Files: + + The minimum defconfig file is simply the generated .config file with + CONFIG_APPS_DIR setting removed or commented out. That setting provides + the name and location of the apps/ directory relative to the nuttx build + directory. The default is ../apps/, however, the apps directory may be + any other location and may have a different name. For example, the name + of versioned NuttX releases are always in the form apps-xx.yy where xx.yy + is the version number. + + Finding the apps/ Directory Path: + + When the default configuration is installed using one of the scripts or + programs in the NuttX tools directory, there will be an option to provide + the path to the apps/ directory. If not provided, then the configure tool + will look around and try to make a reasonable decision about where the + apps/ directory is located. + + Compressed defconfig Files: + + The Makefile also supports an option to generate very small defconfig + files. The .config files are quite large and complex. But most of the + settings in the .config file simply have the default settings from the + Kconfig files. These .config files can be converted into small defconfig + file: + + make savedefconfig + + That make target will generate a defconfig file in the top-level + directory. The size reduction is really quite remarkable: + + wc -l .config defconfig + 1085 .config + 82 defconfig + 1167 total + + In order to be usable, the .config file installed from the compressed + defconfig file must be reconstituted using: + + make olddefconfig + + NOTE 1: Only compressed defconfig files are retained in the NuttX repository. + All patches and PRs that attempt to add or modify a defconfig file MUST + use the compressed defconfig format as created by 'make savdefconfig.' + + NOTE 2: When 'make savedefconfig' runs it will try several things some of + which are expected to fail. In these cases you will see an error message + from make followed by "(ignored)." You should also ignore these messages + + CAUTION: This size reduction was accomplished by removing all setting + from the .config file that were at the default value. 'make olddefconfig' + can regenerate the original .config file by simply restoring those default + settings. The underlying assumption here is, of course, that the default + settings do not change. If the default settings change, and they often + do, then the original .config may not be reproducible. + + So if your project requires 100% reproducibility over a long period of + time, you make want to save the complete .config files vs. the standard, + compressed defconfig file. + + Configuring with "Compressed" defconfig Files: + + As described above defconfig, all NuttX defconfig files are compressed + using 'make savedeconfig'. These compressed defconfig files are + generally not fully usable as they are and may not build the target + binaries that you want because the compression process removed all of + the default settings from the defconfig file. To restore the default + settings, you should run the following after configuring: + + make olddefconfig + + That will restore the the missing defaulted values. + + Using this command after configuring is generally a good practice anyway: + Even if the defconfig files are not "compressed" in this fashion, the + defconfig file may be old and the only way to assure that the installed + .config is is up to date is via 'make oldconfig' or 'make olddefconfig'. + See the paragraph above entitled ""Refreshing Configurations" for + additional information. + +Incompatibilities with Older Configurations +------------------------------------------- + + ***** WARNING ***** + + The current NuttX build system supports *only* the new compressed, + defconfig configuration files generated using the kconfig-frontends tools + as described in the preceding section. Support for the older, legacy, + manual configurations was eliminated in NuttX 7.0; support for + uncompressed .config-files-as-defconfig files was eliminated after + NuttX-7.21. All configurations must now be done using the + kconfig-frontends tool. The older manual configurations and the new + kconfig-frontends configurations are not compatible. Old legacy + configurations can *not* be used with the kconfig-frontends tool and, + hence, cannot be used with releases of NuttX 7.0 and beyond: + + If you run 'make menuconfig' with a legacy configuration the resulting + configuration will probably not be functional. + + Q: How can I tell if a configuration is a new kconfig-frontends + configuration or an older, manual configuration? + + A: Only old, manual configurations will have an appconfig file + + + Q: How can I convert a older, manual configuration into a new, + kconfig-frontends toolchain. + + A: Refer to http://www.nuttx.org/doku.php?id=wiki:howtos:convertconfig + + ***** WARNING ***** + + As described above, whenever you use a configuration, you really should + always refresh the configuration with the following command *before* you + make NuttX: + + make oldconfig + + OR + + make olddefconfig + + This will make sure that the configuration is up-to-date in the event that + it has lapsed behind the current NuttX development (see the paragraph + "Refreshing Configurations" above). But this only works with *new* + configuration files created with the kconfig-frontends tools. + + Further, this step is *NOT* optional with the new, compressed defconfig + files. It is a necessary step that will also uncompress the defconfig + file, regenerating the .config and making it usable for NuttX builds. + + Never do 'make oldconfig' (OR 'make menuconfig') on a configuration that + has not been converted to use the kconfig-frontends tools! This will + damage your configuration (see + http://www.nuttx.org/doku.php?id=wiki:howtos:convertconfig). + +NuttX Configuration Tool under DOS +---------------------------------- + + Recent versions of NuttX support building NuttX from a native Windows + console window (see "Native Windows Build" below). But kconfig-frontends + is a Linux tool. At one time this was a problem for Windows users, but + now there is a specially modified version of the kconfig-frontends tools + that can be used: + http://uvc.de/posts/linux-kernel-configuration-tool-mconf-under-windows.html + + The configuration steps most recent versions of NuttX require the + kconfig-tweak tool that is not not available in the the above. However, + there has been an update to this Kconfig Windows tools that does include + kconfig-tweak: http://reclonelabs.com/more-kconfig-awesomeness-for-windows/ + + Source code is available here: https://github.com/reclone/kconfig-frontends-win32 + and https://github.com/reclone/kconfig-frontends-win32/releases + + It is also possible to use the version of kconfig-frontends built + under Cygwin outside of the Cygwin "sandbox" in a native Windows + environment: + + 1. You can run the configuration tool using Cygwin. However, the + Cygwin Makefile.win will complain so to do this will, you have + to manually edit the .config file: + + a. Delete the line: CONFIG_WINDOWS_NATIVE=y + b. Change the apps/ directory path, CONFIG_APPS_DIR to use Unix + style delimiters. For example, change "..\apps" to "../apps" + + And of course, after you use the configuration tool you need to + restore CONFIG_WINDOWS_NATIVE=y and the correct CONFIG_APPS_DIR. + + 2) You can, with some effort, run the Cygwin kconfig-mconf tool + directly in the Windows console window. In this case, you do not + have to modify the .config file, but there are other complexities: + + a. You need to temporarily set the Cygwin directories in the PATH + variable then run kconfig-mconf manually like: + + kconfig-mconf Kconfig + + There is a Windows batch file at tools/kconfig.bat that automates + these steps: + + tools/kconfig menuconfig + + b. There is an issue with accessing DOS environment variables from + the Cygwin kconfig-mconf running in the Windows console. The + following change to the top-level Kconfig file seems to work + around these problems: + + config APPSDIR + string + - option env="APPSDIR" + + default "../apps" + +TOOLCHAINS +^^^^^^^^^^ + +Cross-Development Toolchains +---------------------------- + + In order to build NuttX for your board, you will have to obtain a cross- + compiler to generate code for your target CPU. For each board, + configuration, there is a README.txt file (at + boards////README.txt). + That README file contains suggestions and information about appropriate + tools and development environments for use with your board. + + In any case, the PATH environment variable will need to be updated to + include the location where the build can find the toolchain binaries. + +NuttX Buildroot Toolchain +------------------------- + + For many configurations, a DIY set of tools is available for NuttX. These + tools can be downloaded from the NuttX Bitbucket.org file repository. After + unpacking the buildroot tarball, you can find instructions for building + the tools in the buildroot/boards/README.txt file. + + Check the README.txt file in the configuration directory for your board + to see if you can use the buildroot toolchain with your board (this + README.txt file is located in + boards////README.txt). + + This toolchain is available for both the Linux and Cygwin development + environments. + + Advantages: (1) NuttX header files are built into the tool chain, + and (2) related support tools like NXFLAT tools, the ROMFS + genromfs tools, and the kconfig-frontends tools can be built into your + toolchain. + + Disadvantages: This tool chain is not was well supported as some other + toolchains. GNU tools are not my priority and so the buildroot tools + often get behind. For example, until recently there was no EABI support + in the NuttX buildroot toolchain for ARM. + + NOTE: For Cortex-M3/4, there are OABI and EABI versions of the buildroot + toolchains. If you are using the older OABI toolchain the prefix for + the tools will be arm-nuttx-elf-; for the EABI toolchain the prefix will + be arm-nuttx-eabi-. If you are using the older OABI toolchain with + an ARM Cortex-M3/4, you will need to set CONFIG_ARMV7M_OABI_TOOLCHAIN + in the .config file in order to pick the right tool prefix. + + If the make system ever picks the wrong prefix for your toolchain, you + can always specify the prefix on the command to override the default + like: + + make CROSSDEV=arm-nuttx-elf + +SHELLS +^^^^^^ + + The NuttX build relies on some shell scripts. Some are inline in the + Makefiles and many are executable scripts in the tools/. directory. The + scripts were all developed using bash and many contain bash shell + dependencies. + + Most of the scripts begin with #!/bin/bash to specifically select the + bash shell. Some still have #!/bin/sh but I haven't heard any complaints + so these must not have bash dependencies. + + There are two shell issues that I have heard of: + + 1. Linux where /bin/sh refers to an incompatible shell (like ksh or csh). + + In this case, bash is probably available and the #!/bin/bash at the + beginning of the file should do the job. If any scripts with #!/bin/sh + fail, try changing that to #!/bin/bash and let me know about the change. + + 2. FreeBSD with the Bourne Shell and no bash shell. + + The other, reverse case has also been reported on FreeBSD setups that + have the Bourne shell, but not bash. In this base, #!/bin/bash fails + but #!/bin/sh works okay. My recommendation in this case is to create + a symbolic link at /bin/bash that refers to the Bourne shell. + + There may still be issues, however, with certain the bash-centric scripts + that will require modifications. + +BUILDING NUTTX +^^^^^^^^^^^^^^ + +Building +-------- + + NuttX builds in-place in the source tree. You do not need to create + any special build directories. Assuming that your Make.defs is setup + properly for your tool chain and that PATH environment variable contains + the path to where your cross-development tools are installed, the + following steps are all that are required to build NuttX: + + cd{TOPDIR} + make + + At least one configuration (eagle100) requires additional command line + arguments on the make command. Read + {TOPDIR}/boards////README.txt to see + if that applies to your target. + +Re-building +----------- + + Re-building is normally simple -- just type make again. + + But there are some things that can "get you" when you use the Cygwin + development environment with Windows native tools. The native Windows + tools do not understand Cygwin's symbolic links, so the NuttX make system + does something weird: It copies the configuration directories instead of + linking to them (it could, perhaps, use the NTFS 'mklink' command, but it + doesn't). + + A consequence of this is that you can easily get confused when you edit + a file in one of the linked (i.e., copied) directories, re-build NuttX, + and then not see your changes when you run the program. That is because + build is still using the version of the file in the copied directory, not + your modified file! + + Older versions of NuttX did not support dependencies in this + configuration. So a simple work around this annoying behavior in this + case was the following when you re-build: + + make clean_context all + + This 'make' command will remove of the copied directories, re-copy them, + then make NuttX. + + However, more recent versions of NuttX do support dependencies for the + Cygwin build. As a result, the above command will cause everything to be + rebuilt (because it removes and will cause recreating the + include/nuttx/config.h header file). A much less gracefully but still + effective command in this case is the following for the ARM configuration: + + rm -rf arch/arm/src/chip arch/arm/src/board + + This "kludge" simple removes the copied directories. These directories + will be re-created when you do a normal 'make' and your edits will then be + effective. + +Build Targets and Options +------------------------- + + Build Targets: + Below is a summary of the build targets available in the top-level + NuttX Makefile: + + all + + The default target builds the NuttX executable in the selected output + formats. + + clean + + Removes derived object files, archives, executables, and temporary + files, but retains the configuration and context files and directories. + + distclean + + Does 'clean' then also removes all configuration and context files. + This essentially restores the directory structure to its original, + unconfigured stated. + + Application housekeeping targets. The APPDIR variable refers to the user + application directory. A sample apps/ directory is included with NuttX, + however, this is not treated as part of NuttX and may be replaced with a + different application directory. For the most part, the application + directory is treated like any other build directory in the Makefile script. + However, as a convenience, the following targets are included to support + housekeeping functions in the user application directory from the NuttX + build directory. + + apps_clean + + Perform the clean operation only in the user application directory + + apps_distclean + + Perform the distclean operation only in the user application directory. + The apps/.config file is preserved so that this is not a "full" distclean + but more of a configuration "reset" for the application directory. + + export + + The export target will package the NuttX libraries and header files into + an exportable package. Caveats: (1) These needs some extension for the KERNEL + build. (2) The logic in tools/mkexport.sh only supports GCC and, for example, + explicitly assumes that the archiver is 'ar' + + download + + This is a helper target that will rebuild NuttX and download it to the target + system in one step. The operation of this target depends completely upon + implementation of the DOWNLOAD command in the user Make.defs file. It will + generate an error an error if the DOWNLOAD command is not defined. + + The following targets are used internally by the make logic but can be invoked + from the command under certain conditions if necessary. + + depend + + Create build dependencies. (NOTE: There is currently no support for build + dependencies under Cygwin using Windows-native toolchains.) + + context + + The context target is invoked on each target build to assure that NuttX is + properly configured. The basic configuration steps include creation of the + the config.h and version.h header files in the include/nuttx directory and + the establishment of symbolic links to configured directories. + + clean_context + + This is part of the distclean target. It removes all of the header files + and symbolic links created by the context target. + + Build Options: + Of course, the value any make variable an be overridden from the make command + line. However, there is one particular variable assignment option that may + be useful to you: + + V=1 + + This is the build "verbosity flag." If you specify V=1 on the make command + line, you will see the exact commands used in the build. This can be very + useful when adding new boards or tracking down compile time errors and + warnings (Contributed by Richard Cochran). + +Native Windows Build +-------------------- + + The beginnings of a Windows native build are in place but still not often + used as of this writing. The build was functional but because of lack of + use may find some issues to be resolved with this build configuration. + + The windows native build logic initiated if CONFIG_WINDOWS_NATIVE=y is + defined in the NuttX configuration file: + + This build: + + - Uses all Windows style paths + - Uses primarily Windows batch commands from cmd.exe, with + - A few extensions from GNUWin32 + + In this build, you cannot use a Cygwin or MSYS shell. Rather the build must + be performed in a Windows console window. Here is a better terminal than the + standard issue, CMD.exe terminal: ConEmu which can be downloaded from: + https://sourceforge.net/projects/conemu/ or https://conemu.github.io/ . + + Build Tools. The build still relies on some Unix-like commands. I use + the GNUWin32 tools that can be downloaded from http://gnuwin32.sourceforge.net/ + using the 'Download all' selection. Individual packages can be download + instead if you know what you are doing and want a faster download (No, I + can't tell you which packages you should or should not download). + + Host Compiler: I use the MingGW GCC compiler which can be downloaded from + http://www.mingw.org/. If you are using GNUWin32, then it is recommended + the you not install the optional MSYS components as there may be conflicts. + + This capability should still be considered a work in progress because: + + (1) It has not been verified on all targets and tools, and + (2) it still lacks some of the creature-comforts of the more mature + environments. + +Installing GNUWin32 +------------------- + + The Windows native build will depend upon a few Unix-like tools that can be + provided either by MSYS or GNUWin32. The GNUWin32 are available from + http://gnuwin32.sourceforge.net/. GNUWin32 provides ports of tools with a + GPL or similar open source license to modern MS-Windows (Microsoft Windows + 2000 / XP / 2003 / Vista / 2008 / 7). See + http://gnuwin32.sourceforge.net/packages.html for a list of all of the tools + available in the GNUWin32 package. + + The SourceForge project is located here: + http://sourceforge.net/projects/gnuwin32/. The project is still being + actively supported (although some of the Windows ports have gotten very old). + + Some commercial toolchains include a subset of the GNUWin32 tools in the + installation. My recommendation is that you download the GNUWin32 tools + directly from the sourceforge.net website so that you will know what you are + using and can reproduce your build environment. + + GNUWin32 Installation Steps: + + The following steps will download and execute the GNUWin32 installer. + + 1. Download GetGNUWin32-x.x.x.exe from + http://sourceforge.net/projects/getgnuwin32/files/. This is the + installer. The current version as of this writing is 0.6.3. + + 2. Run the installer. + + 3. Accept the license. + + 4. Select the installation directory. My recommendation is the + directory that contains this README file (). + + 5. After running GetGNUWin32-0.x.x.exe, you will have a new directory + /GetGNUWin32 + + Note that the GNUWin32 installer didn't install GNUWin32. Instead, it + installed another, smarter downloader. That downloader is the GNUWin32 + package management tool developed by the Open SSL project. + + The following steps probably should be performed from inside a DOS shell. + + 6. Change to the directory created by GetGNUWin32-x.x.x.exe + + cd GetGNUWin32 + + 7. Execute the download.bat script. The download.bat script will download + about 446 packages! Enough to have a very complete Linux-like environment + under the DOS shell. This will take awhile. This step only downloads + the packages and the next step will install the packages. + + download + + 8. This step will install the downloaded packages. The argument of the + install.bat script is the installation location. C:\gnuwin32 is the + standard install location: + + install C:\gnuwin32 + + NOTE: This installation step will install *all* GNUWin32 packages... far + more than you will ever need. If disc space is a problem for you, you might + need to perform a manual installation of the individual ZIP files that you + will find in the /GetGNUWin32/packages directory. + +CYGWIN BUILD PROBLEMS +^^^^^^^^^^^^^^^^^^^^^ + +Performance +----------- + + Build performance under Cygwin is really not so bad, certainly not as good + as a Linux build. However, often you will find that the performance is + not just bad but terrible. If you are seeing awful performance.. like two + or three compilations per second.. the culprit is usually your Windows + Anti-Virus protection interfering with the build tool program execution. + + I use Cygwin quite often and I use Windows Defender. In order to get good + build performance, I routinely keep the Windows Defender "Virus & Threat + Protections Settings" screen up: I disable "Real-Time Protection" just + before entering 'make' then turn "Real-Time Protection" back on when the + build completes. With this additional nuisance step, I find that build + performance under Cygwin is completely acceptable. + +Strange Path Problems +--------------------- + + If you see strange behavior when building under Cygwin then you may have + a problem with your PATH variable. For example, if you see failures to + locate files that are clearly present, that may mean that you are using + the wrong version of a tool. For example, you may not be using Cygwin's + 'make' program at /usr/bin/make. Try: + + which make + /usr/bin/make + + When you install some toolchains (such as Yargarto or CodeSourcery tools), + they may modify your PATH variable to include a path to their binaries. + At that location, they may have GNUWin32 versions of the tools. So you + might actually be using a version of make that does not understand Cygwin + paths. + + The solution is either: + + 1. Edit your PATH to remove the path to the GNUWin32 tools, or + 2. Put /usr/local/bin, /usr/bin, and /bin at the front of your path: + + export PATH=/usr/local/bin:/usr/bin:/bin:$PATH + +Window Native Toolchain Issues +------------------------------ + + There are many popular Windows native toolchains that may be used with NuttX. + Examples include CodeSourcery (for Windows), devkitARM, and several vendor- + provided toolchains. There are several limitations with using a and Windows + based toolchain in a Cygwin environment. The three biggest are: + + 1. The Windows toolchain cannot follow Cygwin paths. Path conversions are + performed automatically in the Cygwin makefiles using the 'cygpath' utility + but you might easily find some new path problems. If so, check out 'cygpath -w' + + 2. Windows toolchains cannot follow Cygwin symbolic links. Many symbolic links + are used in Nuttx (e.g., include/arch). The make system works around these + problems for the Windows tools by copying directories instead of linking them. + But this can also cause some confusion for you: For example, you may edit + a file in a "linked" directory and find that your changes had no effect. + That is because you are building the copy of the file in the "fake" symbolic + directory. If you use a Windows toolchain, you should get in the habit of + making like this: + + make clean_context all + + An alias in your .bashrc file might make that less painful. The rebuild + is not a long as you might think because there is no dependency checking + if you are using a native Windows toolchain. That bring us to #3: + +General Pre-built Toolchain Issues +---------------------------------- + + To continue with the list of "Window Native Toolchain Issues" we can add + the following. These, however, are really just issues that you will have + if you use any pre-built toolchain (vs. building the NuttX toolchain from + the NuttX buildroot package): + + There may be incompatibilities with header files, libraries, and compiler + built-in functions detailed below. For the most part, these issues + are handled in the existing make logic. But if you are breaking new ground, + then you may encounter these: + + 4. Header Files. Most pre-built toolchains will build with a foreign C + library (usually newlib, but maybe uClibc or glibc if you are using a + Linux toolchain). This means that the header files from the foreign + C library will be built into the toolchain. So if you "include ", + you will get the stdio.h from the incompatible, foreign C library and + not the nuttx stdio.h (at nuttx/include/stdio.h) that you wanted. + + This can cause confusion in the builds and you must always be + sure the -nostdinc is included in the CFLAGS. That will assure that + you take the include files only from + + 5. Libraries. What was said above header files applies to libraries. + You do not want to include code from the libraries of any foreign + C libraries built into your toolchain. If this happens you will get + perplexing errors about undefined symbols. To avoid these errors, + you will need to add -nostdlib to your CFLAGS flags to assure that + you only take code from the NuttX libraries. + + This, however, may causes other issues for libraries in the toolchain + that you do want (like libgcc.a or libm.a). These are special-cased + in most Makefiles, but you could still run into issues of missing + libraries. + + 6. Built-Ins. Some compilers target a particular operating system. + Many people would, for example, like to use the same toolchain to + develop Linux and NuttX software. Compilers built for other + operating systems may generate incompatible built-in logic and, + for this reason, -fno-builtin should also be included in your + C flags + + And finally you may not be able to use NXFLAT. + + 7. NXFLAT. If you use a pre-built toolchain, you will lose all support + for NXFLAT. NXFLAT is a binary format described in + Documentation/NuttXNxFlat.html. It may be possible to build + standalone versions of the NXFLAT tools; there are a few examples + of this in the buildroot repository at https://bitbucket.org/nuttx/buildroot + However, it is possible that there could be interoperability issues + with your toolchain since they will be using different versions of + binutils and possibly different ABIs. + +Building Original Linux Boards in Cygwin +---------------------------------------- + + Some default board configurations are set to build under Linux and others + to build under Windows with Cygwin. Various default toolchains may also + be used in each configuration. It is possible to change the default + setup. Here, for example, is what you must do in order to compile a + default Linux configuration in the Cygwin environment using the + CodeSourcery for Windows toolchain. After instantiating a "canned" + NuttX configuration, run the target 'menuconfig' and set the following + items: + + Build Setup->Build Host Platform->Windows + Build Setup->Windows Build Environment->Cygwin + System Type->Toolchain Selection->CodeSourcery GNU Toolchain under Windows + + In Windows 7 it may be required to open the Cygwin shell as Administrator + ("Run As" option, right button) you find errors like "Permission denied". + +Recovering from Bad Configurations +---------------------------------- + + Many people make the mistake of configuring NuttX with the "canned" + configuration and then just typing 'make' with disastrous consequences; + the build may fail with mysterious, uninterpretable, and irrecoverable + build errors. If, for example, you do this with an unmodified Linux + configuration in a Windows/Cgwin environment, you will corrupt the + build environment. The environment will be corrupted because of POSIX vs + Windows path issues and with issues related to symbolic links. If you + make the mistake of doing this, the easiest way to recover is to just + start over: Do 'make distclean' to remove every trace of the corrupted + configuration, reconfigure from scratch, and make certain that the set + the configuration correctly for your platform before attempting to make + again. + + Just fixing the configuration file after you have instantiated the bad + configuration with 'make' is not enough. + +DOCUMENTATION +^^^^^^^^^^^^^ + +Additional information can be found in the Documentation/ directory and +also in README files that are scattered throughout the source tree.

Release Notes +=================== + +This file contains are the release notes for the NuttX (and apps) packages +for every release. The text is just as was written at the time of release +(with perhaps some corrected typos). Over the course of time, NuttX has +used several different repositories: CVS, two SVN repositories, and +currently a GIT repository. Therefore, revision information specific to an +older repository may not be meaningful today. + +To make it easier to track there older versions in the current GIT +repository, a GIT lightweight tag has been applied for each release. The +tag name is the release name (for example, the release 6.27 has tag name +"nuttx-6.27"). + +NuttX-0.1.0 +----------- + +This is the initial. This initial includes the complete NuttX RTOS +with support for the Linux user mode simulation and the TI TMS320C5471 +(Arm7) processor. Partial support for the 87C52 is included. + +This release has been verified on both the Linux user-mode and C5471 +platforms using the test program under examples/ostest. Test results +for the C5471 can be found in arch/c5471/doc/test-results.txt. + +This tarball contains a complete CVS snapshot from March 9,2007. + +NuttX-0.1.1 +----------- + +This is the second release of NuttX.

This release includes the initial +integration of a network subsystem and the uIP TCP/IP stack into NuttX +(see http://www.sics.se/~adam/uip/index.php/Main_Page). Also included +is a device driver for the Davicom DM90x0 Ethernet controller. + +This integration is very preliminary. Only a small portion of the +network functionality has been integrated and there are a number of +open issues (see the TODO file). The network subsystem is pre-alpha +at this point in time. I expect that it will stabilize and mature +over the next few releases. + +The baseline functionality of NuttX continues to mature and remains at +post-beta (as long as the network is not used). + +See the ChangeLog for a complete list of changes. + +This release has been verified only on the Neuros OSD (DM320 ARM9) +platform using the DM90x0 driver. + +This tarball contains a complete CVS snapshot from November 6, 2007. + +NuttX-0.3.1 +----------- + +This is the 13th release of NuttX and the second release containing +the integration of a network subsystem and the uIP TCP/IP, UDP, and +ICMP stacks into NuttX (see http://www.sics.se/~adam/uip/index.php/Main_Page). + +Many network-related problems have been fixed and the implementation +has matured significantly. However, the level of network reliability +is probably still at the pre-alpha or early level. It is sufficiently +complete that you may begin to perform some network integration and +is expected to achieve beta level of reliability over the next few +releases. + +The baseline functionality of NuttX continues to mature and remains at +post-beta (as long as the network is not used). + +See the ChangeLog for a complete list of changes. + +This release has been verified only on the Neuros OSD (DM320 ARM9) +platform using the DM90x0 driver. + +This tarball contains a complete CVS snapshot from November 19, 2007. + +NuttX-0.3.2 +----------- + +This is the 14th release of NuttX and the 3rd release containing +the integration of a network subsystem and the uIP TCP/IP, UDP, and +ICMP stacks into NuttX (see http://www.sics.se/~adam/uip/index.php/Main_Page). + +Many network-related problems have been fixed and the implementation +has matured significantly. This release consists of: + +o TCP-related bug-fixes +o TCP performance improvements +o Initial UDP integration +o Initial uIP micro webserver integration + +See the ChangeLog for a complete list of changes. + +The level of network reliability is at alpha level is expected to +achieve beta level of reliability over the next few releases. + +The baseline functionality of NuttX continues to mature and remains at +post-beta. + +This release has been verified only on the Neuros OSD (DM320 ARM9) +platform using the DM90x0 driver. + +This tarball contains a complete CVS snapshot from November 23, 2007. + +NuttX-0.3.3 +----------- + +This is the 15th release of NuttX and the 4th release containing +the integration of a network subsystem and the uIP TCP/IP, UDP, and +ICMP stacks into NuttX (see http://www.sics.se/~adam/uip/index.php/Main_Page). + +Many network-related problems have been fixed and the implementation +has matured significantly. This release consists of: + +o TCP-related bug-fixes for disconnecting sockets +o Correction of some TCP read-ahead logic +o TCP performance improvements +o Misc. additions and cleanup (See the ChangeLog for a complete list of + changes). + +The level of network reliability is at an early beta release level. The +baseline functionality of NuttX continues to mature and remains at +post-beta. Open network-related issues include only: + +o Some minor unimplemented BSD socket functionality, +o Thread safety issues: the same socket cannot be used concurrently on + different threads. +o Pending design changes necessary to support multiple network interfaces. +o IPv6 support is incomplete. + +This release has been verified only on the Neuros OSD (DM320 ARM9) +platform using the DM90x0 driver. Any feedback for improving the network +reliability/performance would be greatly appreciated. + +This tarball contains a complete CVS snapshot from November 28, 2007. + +NuttX-0.3.4 +----------- + +This is the 16th release of NuttX and the 5th release containing +the integration of a network subsystem and the uIP TCP/IP, UDP, and +ICMP stacks into NuttX (see http://www.sics.se/~adam/uip/index.php/Main_Page). + +This release is primarily a bug-fix release. New features include +only: + +o TELNET front-end to NSH, +o DHCPC server functionality, and +o C5471 Ethernet driver. + +Numerous network related problems were fixed related to DHCPC, UDP +input processing, UDP broadcast, send timeouts, and bad compilation when +uIP is compiled at high levels of optimization. + +The level of network reliability is at a strong beta release level. The +baseline functionality of NuttX continues to mature and remains at +post-beta or production level. + +Parts of this release were verified only on the Neuros OSD (DM320 ARM9) +platform using the DM90x0 Ethernet driver and other parts on the Spectrum +Digital C5471 EVM using the C5471 Ethernet driver. Any feedback about bugs +or suggestions for improving the network reliability/performance would be +greatly appreciated. + +This tarball contains a complete CVS snapshot from December 10, 2007. + +NuttX-0.3.5 +----------- + +This is the 17th release of NuttX this release is primarily a bug-fix +release and intended to synchronize with the current CVS contents. See +the ChangeLog for a detailed list of changes and fixes. + +This release were verified only on the Spectrum Digital C5471 EVM using +the C5471 Ethernet driver. Any feedback about bugs or suggestions for +improvement would be greatly appreciated. + +This tarball contains a complete CVS snapshot from December 18, 2007. + +NuttX-0.3.6 +----------- + +This is the 18th release of NuttX. This release contains on a few +changes. The primary purpose of this release is to synchronize with +the release of the pascal-0.1.0 add-on package. + +This release of NuttX includes the following changes: + +* Fixes for use with SDCC compiler +* Added a simulated z80 target (arch/z80) +* Fix deadlock errors when using stdio but with no buffering +* Add support for the add-on Pascal P-Code interpreter (pcode/) + (see the pascal-0.1.0 package) + +This release were verified only on the simulated Z80 and host +simulation targets. As usual, any feedback about bugs or suggestions +for improvement would be greatly appreciated. + +This tarball contains a complete CVS snapshot from January 6, 2007. + +==== + +There was an error in the initial 0.3.6 release that prevented +a successful build unless the Pascal add-on was present. The +tarball was patched to include the fix. Make sure that you download +the nuttx-0.3.6.1.tar.gz version to avoid this problem. + +NuttX-0.3.7 +----------- + +This is the 19th release of NuttX. This release includes the +preliminary port of NuttX to the ZiLOG z16f 16-bit microcontroller. +This port was verified using the ZiLOG z16f2800100zcog Development +and the ZiLOG ZDS-II toolchain. See http://www.zilog.com for +further information. + +I emphasize that this is a preliminary release of the z16f port and +is only alpha or, perhaps, pre-alpha quality as of this writing. +There are a list of known issues in the TODO file in the root of +the NuttX directory. The overall quality of NuttX (excluding the +z16f port) continues to improve beyond the late beta level. + +The z16f port required numerous changes to NuttX to handle: + +* NEAR and FAR addressing, and +* Use of a Windows native toolchain in a Cygwin build environment. + +In addition to the z16f port, at least one very critical bug was +found and corrected in NuttX: The thread-specific errno value of one +task was being randomly trashed when a different thread exited. + +This release were verified on the ZiLOG z16f2800100zcog, Neuros OSD +(ARM9), and the simulation platforms. As usual, any feedback about bugs +or suggestions for improvement would be greatly appreciated. + +This tarball contains a complete CVS snapshot from January 31, 2008. + +NuttX-0.3.8 +----------- + +This is the 20th release of NuttX. This is a minor bugfix release. +It corrects a few minor problems, adds a few minor features, and +continues the integration of the ZiLOG Z18F and of the Pascal P-Code +add-on. This release is synchronized with the release of Pascal-0.1.2. + +This tarball contains a complete CVS snapshot from February 10, 2008. + +NuttX-0.3.9 +----------- + +This is the 21st release of NuttX. This is a minor future enhancement +release. This release includes support for the ZiLOG Z8Encore! micro- +controller. Also included is the initial framework for support for +the Z80, XTRS platform (http://www.tim-mann.org/xtrs.html). + +This released has been verified only on the ZiLOG ZDS-II Z8Encore! +chip simulation. + +This tarball contains a complete CVS snapshot from March 9, 2008. + +NuttX-0.3.10 +------------ + +This is the 22nd release of NuttX.

This driver has been verified and is an early alpha + stage in quality. + * TI DM320. Coding for this driver is complete but it is completely + untested as of this release. + +A controller-independent class driver is also included for: + * USB serial class device driver (emulates the Prolific PL2303 + serial-to-USB adapter). This driver has only been verified with + the Linux host PL2303 driver. + +Other new features include: + * Add an option to set aside a separate stack for interrupt + handling (ARM only). This is useful when memory is constrained, + there are multiple tasks, and the interrupt stack requirement + is high (as when USB is enabled). + +A few bugs were also fixed: + * Fixed the frequency of system timer interrupts in the NXP LPC214x port + (off by 20x in nuttx-0.3.15) + * Fixed serial driver bugs related to (1) open counts and (2) recognizing + O_NONBLOCK on read. + * Fixed an error in read(); it was not setting the errno on errors returned + from the driver. + +These changes were verified only on the mcu123.com NXP LPC2148 board +using with a Linux host. Please report any errors to me. + +This tarball contains a complete CVS snapshot from October 10, 2008. + +UPDATE +------ +This release does not build for the ARM target when USB is disabled. +Here is the fix: + +Index: arch/arm/src/common/up_internal.h +=================================================================== +RCS file: /cvsroot/nuttx/nuttx/arch/arm/src/common/up_internal.h,v +retrieving revision 1.13 +diff -u -r1.13 up_internal.h +--- arch/arm/src/common/up_internal.h 6 Oct 2008 16:20:52 -0000 1.13 ++++ arch/arm/src/common/up_internal.h 13 Oct 2008 20:48:21 -0000 +@@ -200,7 +200,8 @@ + extern void up_usbinitialize(void); + extern void up_usbuninitialize(void); + #else +-# define up_netinitialize() ++# define up_usbinitialize() ++# define up_usbuninitialize() + #endif + + #endif /* __ASSEMBLY__ */ + +NuttX-0.3.17 +------------ + +This is the 29th release of NuttX. This release includes the +additional support for USB in NuttX. The following new features +were added: + +* Added support for SPI-based MMC/SD cards (with an SPI driver + for the NXP LPC214x). +* Added USB storage class device side driver (BBB) +* Added an example that demonstrates the USB storage class by + exporting the SPI based MMC/SD card on the NXP LPC214x. + +This is an early alpha release of these drivers. At present they +only work with debug features enabled so there are probably some +race conditions that occur only with debug features disabled. +(Anyone out there with a USB analyzer? I would love to know what +is happening.) + +Several important bugs were also fixed in the FAT file system, USB +serial driver and NXP LPC214x USB controller driver. (See the ChangeLog +for details.) + +These changes were verified only on the mcu123.com NXP LPC2148 board +using a Linux development environment. USB testing was performed +using both a Linux host and a WinXP host. Please report any errors +to me. + +This tarball contains a complete CVS snapshot from October 28, 2008. + +NuttX-0.3.18 +------------ + +This is the 30th release of NuttX. This release includes two +partially completed ports, several new features, and a couple of +important bug fixes. The two partially completed ports are: + + * The STMicro STR71x processor and configuration for the Olimex + STR-P711 board. + * The Hitachi SH-1 using the SH1_LCEVB1 (SH-1/US7032EVB1) board + +Progress on these ports is stalled (as detailed in the ChangeLog). + +The new features focus primarily on management of block devices and +extensions of the NuttShell (NSH). These include: + + * A loop device that converts a file into a block device. + * A block to character (BCH) driver that allow access a block device as + if it were character device. + * Added strcasecmp() and strncasecmp() libc functions. + * Added the 'dd' and 'losetup' commands to NSH. These commands + (along with mkfatfs and mount), give good management of filesystems + on the target. + +Several bugs were fixed, the most important of which are: + + * Fixed a race condition workaround delay in LPC214X SPI logic. + This was also the cause of some bad MMC/SD performance on that + platform. + + * Fixed a recently introduced FAT file system problem: It would + mount a (invalid) FAT file system even if the medium is not formatted! + + * Corrected two other important errors in the FAT lseek() implementation: + 1 - The sectors-per-cluster value was being reset to "1". + 2 - Important lseek logic was omitted when the seek position was zero. + +The FAT filesystem has had many bugs fixed in it and, I think, is +now maturing and becoming stable. + +These changes were verified only on the mcu123.com NXP LPC2148 +board, the Hitachi SH1_LCEVB1 board, and the Linux simulator, all +using a Linux development environment. Please report any errors +to me. + +This tarball contains a complete CVS snapshot from November 16, 2008. + +NuttX-0.3.19 +------------ + +This is the 31st release of NuttX. This release includes the +following new feature: + + * Add poll() and select() APIs that may be used to monitor for + data availability on character devices or TCP/IP sockets. + * Implemented support TCP/IP connection backlog. This allows + select() to wake-up on new connections to a listener socket. + * Added definition of a framebuffer driver and implement framebuffer + drivers for the simulated platform and the TI DM320 (untested + as of the initial check-in). + * Partially developed a graphics framework based on the framebuffer + drivers, however, this will not be ready for use for a few more + releases. Currently this includes only a few color conversion + routines and some rasterizing functions. A tiny windowing system + is under development but not ready for check-in yet. + * Added support for fixed precision math. + * Added support for outgoing multicast packets. + +Several bugs were fixed, the most important of which are: + + * Fixed an important bug in the TCP/IP buffering logic. When + TCP/IP read-ahead is enabled and not recv() is in-place when a + TCP/IP packet is received, the packet is placed into a read-ahead + buffer. However, the old contents of the read-ahead buffer + were not being cleared and old data would contaminate the newly + received buffer. + + * Changed the behavior of the serial driver read. It now returns + data as it is available rather than waiting for the full requested + read size. This makes functions like fgetc() work much more + smoothly. + +These changes were verified only on the Neuros OSD (ARM9) using a +Linux development environment. Please report any errors to me. + +This tarball contains a complete CVS snapshot from November 26, 2008. + +NuttX-0.4.0 +----------- + +This is the 32nd release of NuttX. This release adds graphics +support and a tiny windowing subsystem. That new graphics subsystem +is documented at http://nuttx.sourceforge.net/NXGraphicsSubsystem.html. +No other substantial changes were made. + +These changes were verified only on the NuttX simulation platform +with X11 windows simulating a device framebuffer. Please report any +errors to me. + +The version number was bumped up to 0.4.0 in part to reflect the +new graphics subsystem, but also to recognize the NuttX is approaching +complete functionality. In the 0.3.x versions, network support was +added, Pascal P-code runtime support was added, FAT and ROMFS +filesystems were added, MMC/SD and USB device support were added. +There were also numerous extensions to the NuttShell, NuttX APIs, +and architecture ports. + +This tarball contains a complete CVS snapshot from December 6, 2008. + +NuttX-0.4.1 +----------- + +This is the 33rd release of NuttX. This is a minor bugfix release. +The primary reason for this release is to correct numerous build +errors that have accumulated for the ZiLOG ZDS-II based targets. +All ZDS-II targets now build correctly (but have not been re-tested). +In addition to platform-specific build failures, this release also +adds the following features which were not tested as of the time +of the release: + + * Board support for the ZiLog ez80Acclaim! ez80f910200zco Development Kit + * ZiLOG eZ80F91 EMAC driver + +These changes were verified only on the NuttX simulation platform. +Please report any errors to me. + +This tarball contains a complete CVS snapshot from February 6, 2009. + +NuttX-0.4.2 +----------- + +This is the 34th release of NuttX. This release adds no new OS +features but does include support for two new architectures: + + * ez80Acclaim! Basic support has been integrated and verified + for the ez80f910200zcog-d board (eZ80F91-based). That basic + support includes timer interrupts and serial console. Ongoing + work includes an EMAC driver that should be integrated for the + next release nuttx-0.4.2. eZ80Acclaim! support has been in the + code base for some time, but has only just been integrated due + to toolchain issues. + + * Renesas M16C/20. Support for the Renesas SKP16C20 board has + been included in the NuttX source tree. However, as the + eZ80Acclaim!, testing and integration of that port is stalled + due to toolchain issues. + +These changes were verified only on the ZiLOG eZ80910200zcog-d +board. Please report any errors to me. + +This tarball contains a complete CVS snapshot from February 28, 2009. + +NuttX-0.4.3 +----------- + +This is the 35th release of NuttX. This release one important new +OS feature and corrects and extends the eZ80 port: + + * Priority Inheritance. The basic NuttX waiting logic was extended + to support priority inheritance. See the NuttX User Manual for + further information: + http://www.nuttx.org/NuttxUserGuide.html#priorityinheritance. + + * ez80Acclaim! Corrected several critical, show-stopping bugs on that + platform including: + - Errors in the serial driver interrupts. + - An error in the eZ80 table. + * eZ80Acclaim!: Completed integration of the eZ80F91 EMAC driver. + +These changes were verified only on the ZiLOG eZ80910200zcog-d board +and on Cygwin-based simulation platform in various configurations. +Please report any errors to me. + +This tarball contains a complete CVS snapshot from March 13, 2009. + +NuttX-0.4.4 +----------- + +This is the 36th release of NuttX. This release focuses on bugfixes +and extending and verifying certain networking features. + + * Important bugs were fixed in NSH, UDP checksum calculation, UDP + bind() behavior for port==0, the eZ80Acclaim! EMAC driver, Z80 + interrupt handling, and in the C libraries. + + * Testing was extended to further verify the tiny webserver, + DHCPD, wget(), and sendmail. + +See the Changelog for a detailed description of these changes. + +These changes were verified only on the ZiLOG eZ80910200zcog-d board +using the ZDS-II toolchain in Cygwin-based environment. Please +report any errors to me. + +This tarball contains a complete CVS snapshot from March 29, 2009. + +NuttX-0.4.5 +----------- + +This is the 37th release of NuttX. This release focuses on a few new features. + + * The basic port for the Freescale ARM920T i.MX1 processor on the + Freescale MX1ADS board. Coding is complete for this port, but + it is has not yet fully integrated + * Extended I2C and SPI interface definitions + * Add basic support for C++ applications. Very simple C++ + applications can now be built against NuttX without any external + libraries. At present, only the most primitive C++ programs + are supported, but it is hoped that this support will be extended + in future releases. + +See the Changelog for a detailed description of these changes. + +This tarball contains a complete CVS snapshot from April 19, 2009. + +NuttX-0.4.6 +----------- + +This is the 38th release of NuttX. The release features support +for the Micromint Eagle-100 development board. This board is based +around, the Luminary LM3S6918 MCU. This is the first ARM Cortex-M3 +architecture supported by Nuttx. This initial, basic port includes +timer and serial console with configurations to execute the NuttX +OS test and to run the NuttShell (NSH). Work is still underway on +this port and current plans are to have I2C, SSI, MMC/SD, and +Ethernet driver in the 0.4.7 release. + +Additional work was done on the MXADS i.MX1 port, however, that +work has been set aside until I complete work on the Eagle-100 (I +also need to come up with a 3V power supply). + +Other changes in this release include: Extensions to the SPI interface +definition in order to handle 9-bit interfaces to displays. Several +bugs were fixed (see the ChangeLog for a complete list of changes). + +This tarball contains a complete CVS snapshot from May 19, 2009. + +NuttX-0.4.7 +----------- + +This is the 39th release of NuttX. This release focuses on cleaning +up and extending the Eagle100/LM3S6918 port released in nuttx-0.4.6 +and on improved MMC/SD support. New features include: + + * Improved reliably and additional drivers for the Eagle-100 board + (LM3S6918 ARM Cortex-M3). Additional drivers include Ethernet, + SSI, and support for the on-board LEDs and microSD cards. + + * The SPI-based MMC/SD driver was extended to support SDHC Version + 2.xx cards. + +In addition, this release includes several important bugfixes for +the LM3S6918, the LPC2148, the SPI-based MMC/SD driver, and to +FAT32. See the ChangeLog for details of these bugfixes. + +This tarball contains a complete CVS snapshot from May 29, 2009. + +NuttX-0.4.8 +----------- + +This is the 40th release of NuttX. This release adds: + + * Support for the Olimex STRP711 board. That board is based on + the STMicro STR711 MCU (ARM7TDMI). Integration is complete on + the basic port (boot logic, system time, serial console). Two + configurations have been verified: (1) The board boots and + passes the OS test with console output visible on UART0, and + the NuttShell (NSH) is fully functional with interrupt driven + serial console. An SPI driver is available but untested (because + the Olimex card slot appears to accept only MMC cards; I have + only SD cards). Additional needed: USB and driver, MMC + integration. + + * Support for the CodeSourcery and devkitARM Windows-native GNU + toolchains. Makefiles have been modified for the LM3S6918, + LPC2148, and STR711 to support these toolchains under Cygwin. + +This tarball contains a complete CVS snapshot from June 13, 2009. + +NuttX-0.4.9 +----------- + +This is the 41st release of NuttX. This release adds: + + * Support for a new binary format call NXFLAT that can be used to + execute separately linked programs in place in a file system. + See http://www.nuttx.org/NuttXNxFlat.html. + + * Several important bugs were files related to networking and ROMFS. + See the ChangeLog for a complete list. + +This tarball contains a complete CVS snapshot from June 26, 2009. + +NuttX-0.4.10 +----------- + +This is the 42nd release of NuttX. This released focused on the +port of Jeff Poskanzer's THTTPD HTTP server (see +http://acme.com/software/thttpd/). As of the 0.4.10 release, that +port is still not fully complete and functional. However, numerous +related bug-fixes and functional additions for THTTPD were added: + + * Several new standard C-library functions (fileno, strstr, + strpbrk, fcntl). + * Improved and extended timing APIs (mktime, gmtime, gmtime_r, + gettimeofday, localtime, localtime_r, and strftime) + * Networking enhancements: recvfrom() and accept() now work with + non-blocking sockets. + * NXFLAT extensions (exec) + * Pattern matching logic. + * And miscellaneous bug fixes (see the ChangeLog for details). + +This tarball contains a complete CVS snapshot from August 8, 2009. + +NuttX-0.4.11 +------------ + +This is the 43rd release of NuttX. This release of NuttX incorporates +the verified port of Jeff Poskanzer's THTTPD HTTP server (see +http://acme.com/software/thttpd/). Many of the key features of +THTTPD have been tested on the Micromint Eagle-100 development board +(Cortex-M3). These tests verify: + + * Serving of files from any file system + * Execution of CGI executable. This release supports execution + of NXFLAT executables on a ROMFS file system + (http://www.nuttx.org/NuttXNxFlat.html) + +A standard CGI interface is used: Information is pasted to the CGI +program via POST commands and via environment variables. CGI socket +I/O is redirected to stdin and stdout so that the CGI program only +need to printf() to send its content back to the HTTP client. + +Another value to this THTTPD integration effort has been that THTTPD +has provided a very good test bed for finding NuttX networking bugs. +Several very critical networking bugs have been fixed with this +0.4.11 release (see the ChangeLog for details). Networking throughput +has also been greatly improved. Anyone using NuttX networking +should consider upgrading to this release. + +This tarball contains a complete CVS snapshot from September 16, 2009 + +NuttX-0.4.12 +------------ + +This is the 44th release of NuttX. This release adds basic support +for the STMicro STM32, Cortex-M3 MCU. The specific port is to the +STMicro STM3210E-EVAL development board based around the STM32F103ZET6 +MCU. Some highlights of this port: + + * This basic port includes boot-up logic, interrupt driven serial + console, and system timer interrupts. + * Includes a basic STMicro RIDE7 project that can be used to + perform basic STM32 board bring-up (due to RIDE7 size limitations, + it cannot be used for the full NuttX bring-up). + * Working, Tested Configurations: the NuttX OS test and the + NuttShell (NSH) example. + +This basic STM32 port will be extended in the 0.4.13 NuttX release. +Functionality needed for complete STM32 support includes: USB +device driver, LCD driver and NX bringup on the development board's +display and MicroSD support. An SPI driver and a DMA support was +included in this 0.4.12 release, but is not yet tested. + +This tarball contains a complete CVS snapshot from October 17, 2009 + +NuttX-0.4.13 +------------ + +This is the 45th release of NuttX. The release extends the support +for the STMicro STM32 microcontroller. Minimal support for the +STM3210E-EVAL development board based around the STM32F103ZET6 MCU +was released in NuttX-0.4.12. This release adds: + + * A simple interface definition to support some FLASH, EEPROM, + NVRAM, etc. devices. + * Verified SPI operation using driver for SPI based FLASH parts + M25P64 and M25P128. + * Improved Cortex-M3 context switching. This should improve + context switching performance be 2x in certain cases. + * Added a USB device-side driver for the STM32. This is an early + release of a very complex driver; some bugs are expected. + * The USB driver has been verified against the USB serial device + class driver. There is at least one known outstanding issue + (see the full bug description in the TODO list). + +This release also corrects some important bugs in the early STM32 release: + + * Fixed several errors the prevented operation of NuttX on an + STM32 development board using USART2 as the serial console. + * Fixed and optimization-dependent race condition in the clock + initialization. + * Fixed a critical bug in the interrupt control logic that could + cause interrupt operations to failed used for interrupts in a + certain range. + +This tarball contains a complete CVS snapshot from November 4, 2009 + +NuttX-4.14 +---------- + +This is the 46th release of NuttX. The release extends the support +for the STMicro STM32 microcontroller. Minimal support for the +STM3210E-EVAL development board based around the STM32F103ZET6 MCU +was released in NuttX-0.4.12 and extended in Nuttx-0.4.13 to include +initial USB support. This completes the STM32F103ZET6 and adds: + +New Generic RTOS Features: + + * Added generic support that can be included in any block driver + to provide read-ahead buffering and write buffering for improved + driver performance. + * Added a generic worker thread that can used to defer processing + from an interrupt to a task. + * Defined a generic SD/SDIO interface can can be bound to a MMC/SD + or SDIO driver to provide SDIO support. + * Implemented a an SDIO-based MMC/SD driver using this new SDIO + interface. + +New STM32 Features: + + * Add support to configure an STM32 input GPIO to generate an + EXTI interrupt. + * Added support for buttons on the STM3210E-EVAL board. + * Implemented an STM32 version of the common the SDIO interface. + * Added a configuration to exercise the STM32 with the USB mass + storage device class example. + +This release also corrects some important bugs in the early STM32 release: + + * Correct error handling in the mount() logic. + * Fixed several STM32 DMA-related issues. Integrated and debugged + STM32 DMA functionality that was added in 0.4.12. + * Fixed several bugs in the STM32 USB device-side driver. + +NOTE: This version, 4.14, is equivalent to what would have been +called 0.4.14 to follow 0.4.13. The zero has been eliminated from +the front of the version number to avoid confusion about the state +of development: Some have interpreted the leading zero to mean +that the code is in some way unstable. That was not the intent. +Beginning in January 2010, I will switch to the 2010.nn versioning +as many others have done to avoid such confusion. + +This tarball contains a complete CVS snapshot from December 2, 2009 + +NuttX-5.0 +--------- + +This is 47th release of NuttX and the successor to nuttx-4.14. This +major revision number has been incremented to indicate that an +incompatibility with previous nuttx releases has been introduced. +This version adopts standard fixed width integer names as specified +by the ANSI C99 standard. The core logic of NuttX is older than +that standard and did not conform to it. + +If you have applications running on NuttX-4.14, those applications +should continue to build and execute without problem on NuttX-5.0. +However, if you have device drivers or other OS-internal logic, you +will probably have to make some minor changes to your code to use +this version. Below is a summary of those changes: + + * If you include sys/types.h to get the non-standard, fixed width + integer types (uint32, uint16, ubyte, etc.), that is no longer + necessary. + * Instead, you will need to include stdint.h where the new fixed + width integer types are defined (uint32_t, uint16_t, uint8_t, etc). + * You will have to change all occurrences of the following types: + + uint32 -> uint32_t + uint16 -> uint16_t + ubyte -> uint8_t + uint8 -> uint8_t + sint32 -> int32_t + sint16 -> int16_t + sint8 -> int8_t + + * In addition, the non-standard type 'boolean' must replaced with + the standard type 'bool'. The type definition for 'bool' is in + stdbool.h + +This change in typing caused small changes to many, many files. It +was verified that all configurations in the release still build +correctly (other than the SDCC-based configurations). Regression +testing was performed on a few configurations, but it is possible +that minor build issues still exist. (If you encounter any, please +let me know and I will help you to fix them.) + +In the course of the regression testing, several important bugs +unrelated to the type changes were found and corrected. + + * Fixed an important error in the RX FIFO handling logic of the + LM3S6918 Ethernet driver. + * Corrected the handling of TCP sequence numbers in the TCP stack. + * And other less important bugs as detailed in the ChangeLog. + +The primary focus of this release was standards compatibility, but +a few new features were added including a (1) Flash Translation +Layer (FTL) that will support filesystems on a FLASH device and (2) +partial ports for the STM32F107VC and HCS12 C9S12NE64 MCUs. Those +ports are very incomplete as of this writing. + +This tarball contains a complete CVS snapshot from December 21, 2009 + +NuttX-5.1 +--------- + +This is the 48th release of NuttX. This release adds support for +two new MCU architectures in various states of development: + +* AT91SAM3U (http://www.atmel.com/products/at91/sam3landing.asp?family_id=605) + + This release adds support for the SAM3U-EK development board with + the AT91SAM3U4E MCU + (http://www.atmel.com/dyn/products/product_card_mcu.asp?part_id=4562). + As with most NuttX architecture releases, the release will be + rolled out in two parts: A basic port and an extended port. + + NuttX-5.1 includes the basic port for the SAM3U-EK board. This + release passes the NuttX OS test and is proven to have a valid + OS implementation. It supports the basic boot-up, serial console + and timer interrupts. A configuration to support the NuttShell + is also included. + + The extended port will also include support for SDIO-based SD + cards and USB device (and possible LCD support). These extensions + may or may not happen by the Nuttx 5.2 release as my plate is + kind of full now. + +* LPC3131 (http://ics.nxp.com/products/lpc3000/lpc313x.lpc314x.lpc315x/) + + This release also adds the complete implementation of the basic + port for the NXP LPC3131 MCU on the Embedded Artists EA3131 board + (http://www.embeddedartists.com/products/kits/lpc3131_kit.php). + That port, unfortunately has stalled due to tools issues. Those + tool issues have been resolved and I am confident that the verified + basic port will be available in NuttX-5.2. + + The extended release will follow and should include SDIO-based + SD card support and device USB. + +A few additional features and bugfixes of a minor nature were also +incorporated as detailed in the ChangeLog. + +NuttX-5.2 +--------- + +This is the 49th release of NuttX. This release completes the +verification of the basic port for the NXP LPC3131 MCU on the +Embedded Artists EA3131 board +(http://www.embeddedartists.com/products/kits/lpc3131_kit.php). +This basic port includes basic boot-up, serial console, and timer +interrupts. This port has been verified on the using the NuttX OS +test and includes a working implementation of the NuttShell (NSH). + +An extended release will follow and should include SDIO-based SD +card support and device USB. + +NuttX-5.3 +--------- + +This is the 50th release of NuttX. This release support for one new +architecture: + + * A basic port for the NXP LPC2378 MCU on the Olimex-LPC2378 + development board was contributed by Rommel Marcelo. + +And extensions to two existing architectures: + + * David Hewson contributed a dual-speed (full/high) USB device-side + driver for the NXP LPC3131 on the Embedded Artists EA3131 + development board. + + * A DMA driver and a high speed MCI driver for the Atmel AT91SAM3U + are included (but not fully tested in this release). + +Two important bugfix was also included: + + * An important fix to the USB mass storage driver was contributed + by David Hewson. + * A serious error in the AT91SAM3U PIO handling was fixed. + +NuttX-5.4 +--------- + +This is the 51st release of NuttX. This release includes one new, +important extension to th NX graphics system (See +http://www.nuttx.org/NXGraphicsSubsystem.html). + +NX was develop a couple years back on hardware that supported only +framebuffer devices, that is, video hardware with video memory +directly converts the memory content to video. However, most MCUs +that NuttX focuses on do not support such video memory; rather, +that typically only support LCDs via parallel or serial interfaces. + +This release of NuttX extends NX so that now renders directly to +the LCD device via its serial or parallel interface. No in-memory +copy of the screen memory need be maintained so this solution should +also work in MCUs with very limited SRAM. + +This initial release of this feature includes the verified NX +extensions plus a driver for the HX8347, 16-bit parallel LCD. This +LCD supports 16-bit RGB (5:6:5). + +NuttX-5.5 +--------- + +This is the 52nd release of NuttX. This release includes one new +port, some new drivers and some important bugfixes: + + * NuttX was ported to the Luminary/TI LM3S6965 Ethernet Evaluation + Kit. At present, that port includes an OS test configuration + and a NuttShell (NSH) configuration with Telnet support. + + MMC/SD and Networking support are provided but not thoroughly + verified in this release: Current development efforts are focused + on porting the NuttX window system (NX) to work with the + Evaluation Kits OLED display. + + * A NuttX Ethernet driver for the Microchip ENC28J60 SPI Ethernet + chip is available in the source tree (but has not yet been fully + verified because I haven't properly connected it to hardware + yet). + + * The Olimex STR-P711 NuttX port was extended to support the + ENC28J60 and some new networking configurations were added. + The ENC28J60 has not been tested on the STR-P711, however, + because of hardware issues (I don't think the USB powered board + provides enough power for the ENC28J60 and I don't have the + right wall wart yet). + + Along the way, external interrupt support (XTI) was added to + the STMicro STR-P711 port and some important bugs were fixed + in the STR-P711 SPI driver. + + * Added (optional) floating point support for printf(). + (Contributed by Yolande Cates.) + + * Corrected an important UDP reference counting error. It was + not a serious error, but it trigger an assertion was IS a serious + error. + +NuttX-5.6 +--------- + +This is the 53rd release of NuttX. This release includes one several +new drivers for existing NuttX ports: + + * This port adds support for the RiT displays P14201 4-bpp, + greyscale OLED. 4-bpp greyscale support was integrated into + the NX graphics sub-system and verified using the TI/Luminary + LP3S6965 Ethernet Evaluation Kit. + + * The M25Px driver was extended for the M24P1 FLASH part (see NOTE). + + * An I2C driver and (basic) SPI driver were added for the NXP + LPC313x port. The I2C interface definition was extended to + efficiently handle multiple I2C transfers. + (Contributed by David Hewson.) + +As well as a few, important USB-related bugfixes (See the ChangeLog +for details). + +This release also includes the beginnings of a port for the NXP +LPC1768 MCU. However, it is too early for that port to be useful +(stay tuned for a future announce of the availability of the LPC1768 +port). + +NuttX-5.7 +--------- + +This is the 54th release of NuttX. This release adds basic support +for one new ARM Cortex-M3 architecture: + + * Added support for NXP LPC1768 MCU as provided on the Nucleus + 2G board from 2G Engineering (http://www.2g-eng.com). + * Some initial files for the LPC17xx family were released in NuttX + 5.6, but the first functional release for the NXP LPC1768/Nucleus2G + occurred with NuttX 5.7. + * That initial basic release included timer interrupts and a + serial console and was verified using the NuttX OS test. + * That release includes a verified NuttShell (NSH) configuration + (see the http://www.nuttx.org/NuttShell.html). + * Also included are unverified SPI and USB device drivers. + +Further efforts include: + (1) development of a DMA support library + (2) SPI-based MMC/SD support + (3) verification of the USB driver + +Watch for announcement of the completed LPC1768 port expected in +NuttX-5.8. + +NuttX-5.8 +--------- + +This is the 55th release of NuttX. This includes several important +bugfixes: + + * Corrects some interrupt vectoring for the TI/Stellarix LM3S + port + * Correct initialization logic for NXP LPC17xxx NuttX ports: + Power was not being provided to the GPIO module! + * Corrected (but did not verify) implementation of the optional + interrupt stack feature (all Cortex M3 architectures). + * Correct a HardFault in the LPC17xx SSP driver. + +Additional minor fixes are also included as detailed in the ChangeLog. + +Several new features have been fully developed and included in this +release, but full verification of most of these new features has +been blocked for a variety of issues: + + * Added microSD support for the NuttShell (NSH) configuration in + the Nucleus2G LPC1768 port. For reasons that have not yet been + determined, I have not successfully accessed the microSD card + as of this writing. + * Two USB configurations were also added for the Nucleus2G board: + One to support the USB serial device and one for the USB mass + storage device. Some testing of the USB driver was performed, + but full verification is stalled for an OTG style USB cable. + * LEDs now work correctly on the Nucleus2G LPC1768 board. + * The NuttX/uIP networking subsystem now supports IGMPv2 client. + IGMP (Internet Group Multicast Protocol) network "appliances" + to join into multicast groups. Outbound traffic to enter and + leave multicast groups has been verified, but full verification + will require a switch capable of multicast. Issues associated + with the receipt of multicast packets are likely. + +NuttX-5.9 +--------- + +This is the 56th release of NuttX. This release is difficult to +categorize; NuttX-5.9 was really released because there were too +many changes accumulating in CVS -- a few important, some unfinished +implementations, and a couple of important bugfixes. + + * By far biggest change in this release is the complete implementation + of on-demand paging support. This feature will allow you to + execute large programs on a mass storage device (such as SPI + FLASH) in a small RAM. All of the core on-demand paging logic + was completed (see http://www.nuttx.org/NuttXDemandPaging.html) + and support was implemented for the ARM-9 family. A test + configuration is in place for the NXP LPC3131. It has been + verified that this new logic does not interfere with normal + fixed-page ARM9 operation, but otherwise this new on-demand + paging feature is untested. + * Add support for the CodeSourcery toolchain to the Olimex-lpc2378 + port and for the Neuros OSD port. + * The Neuros OSD port has been updated to work with the production + v1.0 OSD (previously it only worked with the development board). + * And some miscellaneous feature enhancements as detailed in the + ChangeLog. + +This includes several important bugfixes: + + * NXP LPC17xx - Fixed a critical bug in the GPIO configuration + logic: When attempting to set no pull-up or pull-down (floating), + it would, instead, select pull-down. + + * TI/Luminary LM3Sxxxx - Fixed: + (1) A logic error in an address table lookup. + (2) GPIO port encoding the limited support to only 8 GPIO ports. + + * Corrected the lease time in the DHCPC implementation: It was + not in host byte order. + + * And several other less important bugs as documented in the + ChangeLog: Warnings, cornercase compilation problems, etc. + +NuttX-5.10 +---------- + +This is the 57th release of NuttX. This release includes a combination +of some new features as well as several bugfixes. New features +include: + + * TI/Luminary Stellaris LM3S9B96: + Header file changes contributed by Tiago Maluta. + * TI/Luminary Stellaris LM3S8962: + Header file changes and support for the Stellaris LM3S8962 + Ethernet+CAN Evaluation Board contributed by Larry Arnold. + * On-Demand Paging Support: + The basic logic for the On-Demand Paging feature is complete, + implemented for the NXP LPC3131, and partially tested. See + http://www.nuttx.org/NuttXDemandPaging.html. Some additional + test infrastructure will be needed in order to complete the + verification. See configs/ea3131/README.txt for details. + * Two Pass Build Support: + The make system now supports a two pass build where a relocatable, + partially linked object is created on the first pass and that + object is linked with the NuttX libraries to produce the final + executable on the second pass. This two pass build is currently + only used to support the On-Demand paging feature: The first + pass link forces critical logic into the locked text region; + the second pass builds the NuttX executable more-or-less as + normal. + * CONFIG_APP_DIR: + Generalized the way in which applications are built and linked + with NuttX. The new configuration CONFIG_APP_DIR replaces + CONFIG_EXAMPLE. CONFIG_EXAMPLE used to identify the sub-directory + within the NuttX examples/ directory that held the example + application to be built. That made it awkward to configure to + build an application that resides outside of the NuttX examples/ + directory. CONFIG_APP_DIR is more general; it can be used to + refer to any directory containing the application to be built. + + For people who have their own configurations and/or Makefiles, + you will need to make a couple of changes: + + - Replace all occurrences of CONFIG_EXAMPLE=foobar with + CONFIG_APP_DIR=examples/foobar in all of the configuration + files. + - Replace any occurrences of examples/$(CONFIG_EXAMPLE) with + $(CONFIG_APP_DIR) + - Replace any occurrences of lib$(CONFIG_EXAMPLE)$(LIBEXT) + with libapp$(LIBEXT) in your Makefiles. + - Check any other occurrences of CONFIG_EXAMPLE. + + * Several bugfixes are included as well as code changes to eliminate + some warnings. See the ChangeLog for details. + +NuttX-5.11 +---------- + +This is the 58th release of NuttX. This is a bugfix release. + + * One very important bug fixes a race condition that can occur + using semaphores that can be awakened by signals. Under this + particular race condition, a task could hang waiting for a + semaphore. + * Corrections to lm3s8962 port contributed by Larry Arnold. That + port is purported to work correctly with these changes in place. + +Plus less critical bugfixes as detailed in the ChangeLog. New features +include: + + * A new configuration to support the mbed.org LPC1768 board. + (Contributed by Dave Marples.) + * A driver for the Atmel AT45DB161D 4Mbit SPI FLASH part + +NuttX-5.12 +---------- + +This is the 59th release of NuttX. This is a critical bugfix release. + + * Fixed an important error in the signal trampoline logic. + Essentially, interrupts are re-enabled while the signal handler + executes, but the logic to re-disable the interrupts before + returning from the signal handler trampoline was missing. Under + certain circumstances, this can cause stack corruption. This + was discovered by David Hewson on an ARM9 platform, but since + the code has been leveraged, the bug has been propagated from + ARM to Cortex-M3, AVR32, M16C, SH1, ZNEO, eZ80, Z8, and Z80 -- + almost every architecture. The correction has been incorporated + for all architectures but only verified on a few. + +Other notable changes in NuttX-5.12: + + * A complete port for the AVR32 (AT32UC3B0256) is incorporated + in the source tree. Testing of this port is underway now. This + release was made before verifying this port in order to get the + important bugfix in place. + + * Other miscellaneous bugfix and enhancements as noted in the + ChangeLog. + +NuttX-5.13 +---------- + +This is the 60th release of NuttX. Headlines for this release +include: + + * AVR32, www.mcuzone.com AVR32DEV1 + + The port for the www.mcuzone.com AVRDEV1 board based on the + Atmel AT32UC3B0256 MCU was (almost) fully integrated. The port + now successfully passes the NuttX OS test (examples/ostest). + A NuttShell (NSH) configuration is in place (see the NSH User + Guide at http://www.nuttx.org/NuttShell.html). Testing of that + NSH configuration, however, has been postponed (because it got + bumped by the Olimex LPC1766-STK port -- see below) + + Current Status: I think I have a hardware problem with my serial + port setup. There is a good chance that the NSH port is complete + and functional, but I am not yet able to demonstrate that. At + present, I get nothing coming in the serial RXD line (probably + because the pins are configured wrong or I have the MAX232 + connected wrong). + + A complete port will include drivers for additional AVR32 UC3 + devices -- like SPI and USB --- and will be available in a + later release, time permitting. + + * LPC1766, Olimex LPC1766-STK + + Support for the Olimex-LPC1766 is newly added to NuttX and is + still undergoing development, test, and integration. Verified + configurations for the NuttX OS test and for the NuttShell (NSH, + see the NSH User Guide at http://www.nuttx.org/NuttShell.html. + Additional USB configurations are in the release as well, but + they have not yet been verified. Goals for NuttX-5.14 include: + (1) An Ethernet driver, (2) Verified USB support, and (3) SD + card support. + + * Additional changes and bugfixes as detailed in the ChangeLog. + +NuttX-5.14 +---------- + +The 61st release of NuttX, NuttX-5.14, was made on November 27, +2010. This release includes multiple, important bugfixes as well +as a new driver for the NXP LPC1766. + +This release corresponds with SVN release number: r3137 + +Important bugfixes include: + + * Cortex-M3 Hard Fault. Fixed a hard fault problem that can occur + if certain types of interrupts are pending at the time another + interrupt returns. This problem has only been observed on the + LPC1766 (returning from a SYSTICK interrupt with a pending + Ethernet interrupt). However, it is assumed that all Cortex-M3 + ports could have this as a latent bug. + + * TCP/IP Sequence Number Bug. Corrected errors some important + logic in the way that sequence numbers are managed when send() + sends out packets before a previous packet has been acknowledged. + Some of that send() logic was incompatible with logic in the + uIP layer. Errors seen include: (1) The final final packet in + a sequence of packets might be too large! In the THTTPD example, + this might leave some garbage at the bottom of the display. Or + (2) send() might hang with outstanding, unacknowledged data + (and with no re-transmission requests). This was due to + differences in sequence number handling in send() and in + uip_tcpinput.c; uip_tcpinput.c thought (incorrectly) that all + of the bytes were acknowledged; send.c knew that they were not. + + * One-Shot POSIX Timer Bug. Fixed an error in set-up of a one-shot + POSIX timer. It was using the repetitive timer value (which + is zero in the one-shot case), always resulting in a 10Ms timer! + Found and fixed by Wilton Tong. + +Additional support has been included for the Olimex-LPC1766. Support +for that board was added to NuttX 5.13. This release extends that +support with an Ethernet driver. Verified configurations are now +available for the NuttX OS test, for the NuttShell (NSH, see +http://www.nuttx.org/NuttShell.html), for the NuttX network test, +and for the THTTPD webserver. (Additional USB configurations are +in the release as well, but those have not yet been verified. Goals +for NuttX-5.15 (and beyond) include: (1) Verified USB support, (2) +SD card support, and (3) LCD support. + +NuttX-5.15 +---------- + +The 62nd release of NuttX, NuttX-5.15, was made on December 12, +2010. This release includes several bugfixes as well as feature +enhancements, primarily for the Olimex LPC1766-STK board. + +Important bugfixes included: + + * Additional fixes needed with the TCP sequence number problem + "fixed" in NuttX-5.14. + * In the send() logic, now checks if the destination IP address + is in the ARP table before sending the packet; an ARP request + will go out instead. This improves behavior, for example, on + the first on the first GET request from a browser + * All USB class drivers need to call DEV_CONNECT() when they are + ready to be enumerated. That is, (1) initially when bound to + the USB driver, and (2) after a USB reset. + * The SPI_SETBITS macro was calling the SPI setmode method. + * And several other bug fixes of lower importance (see the + ChangeLog for details). + +And feature enhancements: + + * The LPC176x Ethernet driver was using all of AHB SRAM Bank0 for + Ethernet packet buffers (16K). An option was added to limit + the amount of SRAM used for packet buffering and to re-use any + extra Bank0 memory for heap. + + * Enabled networking and SD/MMC card support in the Olimex + LPC1766-STK NuttShell (NSH) configuration. + + * The LPC176x USB driver is now fully fully functional. + * Added an optional cmddata() method to the SPI interface. Some + devices require an additional out-of-band bit to specify if the + next word sent to the device is a command or data. The cmddata + method provides selection of command or data. + + * A driver for the Nokia 6100 LCD (with either the Phillips PCF8833 + LCD controller and for the Epson S1D15G10 LCD controller) and + an NX graphics configuration for the Olimex LPC1766-STK have + been added. However, neither the LCD driver nor the NX + configuration have been verified as of the this release. + +NuttX-5.16 +---------- + +The 63rd release of NuttX, Version 5.16, was made on January 10, +2010 and is available for download from the SourceForge website. +This release includes initial support for USB host in NuttX. The +USB host infrastructure is new to NuttX. This initial USB host release +is probably only beta quality; it is expected the some bugs remain +in the logic and that the functionality requires extension. + +Below is a summary of the NuttX USB host implementation as extracted +from the NuttX Porting Guide: + + 6.3.9 USB Host-Side Drivers + * include/nuttx/usb/usbhost.h. All structures and APIs needed to + work with USB host-side drivers are provided in this header + file. + * struct usbhost_driver_s. Each USB host controller driver must + implement an instance of struct usbhost_driver_s. This structure + is defined in include/nuttx/usb/usbhost.h. Examples: + arch/arm/src/lpc17xx/lpc17_usbhost.c. + * struct usbhost_class_s. Each USB host class driver must implement + an instance of struct usbhost_class_s. This structure is also + defined in include/nuttx/usb/usbhost.h. Examples: + drivers/usbhost/usbhost_storage.c + * USB Host Class Driver Registry. The NuttX USB host infrastructure + includes a registry. During its initialization, each USB host + class driver must call the interface, usbhost_registerclass() + in order add its interface to the registry. Later, when a USB + device is connected, the USB host controller will look up the + USB host class driver that is needed to support the connected + device in this registry. Examples: drivers/usbhost/usbhost_registry.c, + drivers/usbhost/usbhost_registerclass.c, and + drivers/usbhost/usbhost_findclass.c, + * Detection and Enumeration of Connected Devices. Each USB host + device controller supports two methods that are used to detect + and enumeration newly connected devices (and also detect + disconnected devices): + + int (*wait)(FAR struct usbhost_driver_s *drvr, bool connected); + Wait for a device to be connected or disconnected. + + int (*enumerate)(FAR struct usbhost_driver_s *drvr); + Enumerate the connected device. As part of this enumeration + process, the driver will (1) get the device's configuration + descriptor, (2) extract the class ID info from the configuration + descriptor, (3) call usbhost_findclass() to find the class + that supports this device, (4) call the create() method on + the struct usbhost_registry_s interface to get a class instance, + and finally (5) call the connect() method of the struct + usbhost_class_s interface. After that, the class is in charge + of the sequence of operations. + * Binding USB Host-Side Drivers. USB host-side controller drivers + are not normally directly accessed by user code, but are usually + bound to another, higher level USB host class driver. The class + driver exports the standard NuttX device interface so that the + connected USB device can be accessed just as with other, similar, + on-board devices. For example, the USB host mass storage class + driver (drivers/usbhost/usbhost_storage.c) will register a + standard, NuttX block driver interface (like /dev/sda) that can + be used to mount a file system just as with any other other + block driver instance. In general, the binding sequence is: + + 1. Each USB host class driver includes an initialization entry + point that is called from the application at initialization + time. This driver calls usbhost_registerclass() during this + initialization in order to makes itself available in the + event that the device that it supports is connected. Examples: + The function usbhost_storageinit() in the file + drivers/usbhost/usbhost_storage.c + 2. Each application must include a waiter thread thread that + (1) calls the USB host controller driver's wait() to detect + the connection of a device, and then (2) call the USB host + controller driver's enumerate method to bind the registered + USB host class driver to the USB host controller driver. + Examples: The function nsh_waiter() in the file + configs/nucleus2g/src/up_nsh.c and the function nsh_waiter() + in the file configs/olimex-lpc1766stk/src/up_nsh.c. + 3. As part of its operation during the binding operation, the + USB host class driver will register an instances of a standard + NuttX driver under the /dev directory. To repeat the above + example, the USB host mass storage class driver + (drivers/usbhost/usbhost_storage.c) will register a standard, + NuttX block driver interface (like /dev/sda) that can be + used to mount a file system just as with any other other + block driver instance. Examples: See the call to + register_blockdriver() in the function usbhost_initvolume() + in the file drivers/usbhost/usbhost_storage.c. + +NuttX-5.17 +---------- + +The 64th release of NuttX, Version 5.17, was made on January 19, +2011 and is available for download from the SourceForge website. +This release follows close on the heels of the 5.16 release and +extends the USB host capabilities first introduced in that version. + + * The LPC17xx USB host controller driver was extended to (1) add + support for low-speed devices, (2) handle multiple concurrent + transfers on different endpoints (still only one TD per endpoint), + and (3) handle periodic interrupt endpoint types. + + * Add a USB host HID keyboard class driver. Now you can connect + a standard USB keyboard to NuttX and receive keyboard input for + an application. + +And other changes as detailed in the ChangeLog. + +NuttX-5.18 +---------- + +The 65th release of NuttX, Version 5.18, was made on February 27, +2011 and is available for download from the SourceForge website. +This is first release from the new NuttX SVN repository. This +release is made primarily to keep the release tarball in synchronization +with SVN. Many smaller changes have been made as identified in the +ChangeLog. Headlines include: + + * Incorporate several important uIP patches -- including the well + known patch to handle missing SYNACK. + * The Freescale mc8s12ne64 port is code complete but testing has + not yet begun due to toolchain issues. Added support for the + Future Electronics Group NE64 Badge board. + * Added support for a new STM32 board, the ISOTEL NetClamps VSN + V1.2 ready2go sensor network platform. This board is based on + a STM32F103RET6 and includes some interesting power saving/clock + control extensions. + * USB host support expanded to handle vendor specific USB devices. + * Incorporated the LUFA HID parser. + * Various bugfix as detailed in the ChangeLog + +NuttX-5.19 +---------- + +The 66th release of NuttX, Version 5.19, was made on March 12, 2011 +and is available for download from the SourceForge website. This +release includes several new features in various states of integration +and maturity: + + * 486SX QEMU port. This port supports the Intel 486SX architecture + using the QEMU simulator. Initial functionality is in place a + partially tested. There are still some outstanding issues with + timer interrupts. + * Platform specific application support. A new apps/ directory + appears in this port. This apps/ directory provides a mechanism + for applications using NuttX to have a highly customized + initialization process. It supports a set of end-user applications + than can be executed (1) standalone so you can have a fully + customized application startup, or (2) on top of NSH. Think + of it this way: In a buckled-up embedded application, your + end-user programs will probably have their own dedicated start-up + logic. But, during development, you might want to have you + applications available and executable from the NSH command line. + This apps/ add-on (and NSH hooks) was contributed by Uros to + accomplish just that. + * NSH was also extended to support application specific ROMFS + /etc/init.d/rcS start-up scripts. This feature, as well, as + all of the above-mentioned apps/ directory support was contributed + by Uros Platise + * Additional NSH improvements and bug fixes. See the Changelog + for details. + * This release also provides a new SLIP network driver. This + driver should support point-to-point network communications to + a host using TCP/IP or UDP. This driver is code complete, but + not tested in this release. + * New RAMTRON FRAM driver (contributed by Uros Platise) + * New generic 16550 UART driver. + * Cortex-M3 Power improvements: Waits for Interrupt (WFI) in idle + loop for reduced power consumption (LPC17xx and STM32 only - + contributed by Uros Platise)) + * New waitpid() system interface. + * Additional bugfixes: pipes, stdint.h, STM32 SDIO and SPI drivers + +NuttX-6.0 +--------- + +The 67th release of NuttX, Version 6.0, was made on March 21, 2011 +and is available for download from the SourceForge website. The +version number of this release was bumped from 5.19 to 6.0. A +change in the major revision number is used to reflect an incompatibility +with previous versions. In this release, the NuttX core OS +functionality has been separated from NuttX application-related +functionality. These are provided as separate tarballs: + + * nuttx-6.0.tar.gz, and + * apps-6.0.tar.gz + +The purpose of this separation is both to better organize and +modularize the NuttX source tree, but also to provide better support +for incorporation of end-user applications with Nuttx. + +The incompatibility results from the changes to the board configuration +logic needed to supported the separable application. The major +changes to the configuration include: + + * CONFIG_APPS_DIR - This should not be set. The default is + ../apps. This should only be set if you have a custom, + product-specific application directory in some different location. + + * appconfig - Each board configuration now requires a new file + called 'appconfig.' As its name suggests, this file provides + new configuration information needed by the logic in ../apps. + +In addition to this major reorganization in the directory structure, +this release also includes some important extensions to existing +features and some important bugfixes. These include: + + * The SLIP driver was been well debugged and significantly + re-designed. Now you can have an Ethernet connection to you + board even if you have no Ethernet hardware. How cool is that? + + * The QEMU i486 port is now functional. It has also been reported + to work on the Bifferboard (see http://bifferos.bizhat.com/). + + * And extensions to the uIP driver interface, and + + * Bug fixes to fopen() and STM32 GPIO configuration + +Please see the ChangeLog for details. + +NuttX-6.1 +--------- + +The 68th release of NuttX, Version 6.1, was made on April 10, 2011 +and is available for download from the SourceForge website. The +6.0 release introduced a detach-able application environment to +build applications outside of the NuttX source tree. The primary +purpose of this release is to correct numerous build problems +introduced by that architectural change: + + * In many newer environments, NuttX produced strange Makefile + errors but built correctly in older environments. A fix provided + by Rafael Noronha was incorporated and is reported to fix those + build problems. + * The apps/ directory build system would not handle Windows-native + toolchains due to obscure path formatting issues. + * And other problems as detailed in the Changelog. + +Many additional changes were made in the 6.1 release for another +major architectural change: NuttX will now build as a separately +linked microkernel. In this build option the RTOS builds as a +kernel, applications build separately and interface with kernel via +system calls. Applications run in user mode and kernel logic users +in kernel-mode. This provides a secure environment for NuttX. This +feature is fully coded in NuttX-6.1, but has not been tested due +to higher priority tasks that have arisen. + +Related to this change, support for the Cortex-M3 memory protection +unit (MPU) has been integrated with the NuttX kernel build to provide +an even higher level of security. + +NOTE: This kernel build is an option; the default build configuration +is still the standard, flat, unsecured RTOS as in previous releases. + +Additional new features in this release: + + * Support for LPC17xx GPIO interrupts (with much support from + Decio Renno). + * Basic timer support for STM32 (Contributed by Uros Platise) + * A binfs file system. This is a tiny pseudo file system that + lets named applications to be viewed and accessed in NSH under + the /bin directory. + * An I2C-based driver for the LIS331DL MEMS motion sensor. + (Contributed by Uros Platise.) + * A configuration for the Embedded Artists LPCXpresso LPC1768 board. + * The user_initialize() interface has been removed. + +And several bugfix associated with SD drivers, opendir(), signed +8-bit types (int8_t), and USB serial device. See the ChangeLog for +details. + +NuttX-6.2 +--------- + +The 69th release of NuttX, Version 6.2, was made on May 6, 2011 and +is available for download from the SourceForge website. The 6.2 +release includes several new features: + + * NXFFS: The obvious new feature is NXFFS, the NuttX wear-leveling + FLASH file system. This new file system is intended to be + small for the MCU usage and has some limitations. No formal + documentation of NXFFS yet exists. See the fs/nxffs/README.txt + file for details (see + http://svn.code.sf.net/p/nuttx/code/trunk/nuttx/fs/nxffs/README.txt?view=log) + * Support for NXP LPCXpresso LPC1768 board on the Embedded + Artists base board. The Code Red toolchain is supported under + either Linux or Windows. Verified configurations include + dhcpd, nsh, nx, ostest, thttpd, and usbstorage. + * Support for the Univision UG-9664HSWAG01 OLED with Solomon + Systech SD1305 LCD controller. + * A new RAM MTD driver with FLASH simulation capability. + * A version.h file is now automatically generated so that C code + can now be version aware. + +In addition to these new feature, several important bugfixes are +included in this release correcting problems with dup2(), LPC17xx +GPIO interrupts, LPC17xx UART2/3, the FAT file system, build issues, +and strrch(). See the ChangeLog for more details. + +NuttX-6.3 +--------- + +The 70th release of NuttX follows only a nines days after the release +of version 6.2. It was released on May 15, 2011. This special +back-to-back release was made so that the current released version +of NuttX will correspond to the initial release from the RGMP +project. + +This release adds architecture support and build configuration for +RGMP. RGMP is a project for running GPOS and RTOS simultaneously +on multi-processor platforms. See +http://rgmp.sourceforge.net/wiki/index.php/Main_Page for further +information about RGMP. + +This release also includes support for STM32 FLASH, build improvements, +and initial, incomplete support for the MicroChip PIC32MX MCU. Bug +fixes are included for some build problems, USB host class driver +error handling, NX graphics color mapping, and problems with C +standard I/O buffer flushing. See the ChangeLog for further details. + +NuttX-6.4 +--------- + +The 71st release of NuttX, Version 6.4, was made on June 5, 2011 +and is available for download from the SourceForge website. The +6.4 release includes several new features: + + * A new, full-featured FTP client. This client may be used as a library + for automated FTP or via an FTP client shell. The FTP shell + supports the following commands: cd, chmod, get, help, idle, + login, ls, quit, mkdir, noop, put, pwd, rename, rhelp, rm, + rmdir, size, time, and up. A configuration is available for + the NXP LPC17xx to demonstrate this functionality. + * A functional C1101 wireless driver (contributed by Uros Platise) + * A PCI-based E1000 Ethernet driver (contributed by Yu Qiang) + * New C library functions: inet_addr() (contributed by Yu Qiang), + strndup(), asprintf() + * Reduced memory allocation overhead for MCUs with small heaps (<64K). + * fdopen() now works with socket descriptors allowing standard + buffered C functions to be used for network communications. + * The NSH ifconfig command can now be used to set or change the + IP address (contributed by Yu Qiang) + +This release also includes some completed but untested functionality. + + * The MicroChip PIC32MX port is now code complete and ready to + begin testing. Unfortunately, testing will be delayed due to + tool issues. + * Support for the NXP LPC315x MCUs. + +Additional miscellaneous enhancements and bug fixes to task_delete(), +recvfrom(), and other changes as noted in the ChangeLog. + +NuttX-6.5 +--------- + +The 72nd release of NuttX, Version 6.5, was made on June 21, 2011 +and is available for download from the SourceForge website. The +6.5 release is all about support for the Atmel 8-bit AVR family. +I have been interested in the AVR family for some time but because +of the severe SRAM constraints and because of the availability of +many tiny schedulers for the AVR, it has not been "on the radar +screen." However, I have recently become interested because of +interest expressed by members of the forum and because of the +availability of newer, larger capacity AVR parts (that I don't have +yet). + +This release corresponds with SVN release number: r3730 + +This release includes support for the following AVR boards. As +with any initial support for new architectures, there are some +incomplete areas and a few caveats that need to be stated. Here +they are, ordered from the least to the most complete: + + * SoC Robotics Amber Web Server (ATMega128). + + This port of NuttX to the Amber Web Server from SoC Robotics + (http://www.soc-robotics.com/index.htm). Is only partially in + place. The Amber Web Server is based on an Atmel ATMega128 + (128K FLASH but only 4K of SRAM). + + STATUS: Work on this port has stalled due to toolchain issues. It + is complete, but untested. + + * Micropendous 3 AT9USB647 + + This port of NuttX to the Opendous Micropendous 3 board. The + Micropendous3 may be populated with an AT90USB646, 647, 1286, + or 1287. See http://code.google.com/p/opendous/. I have only + the AT90USB647 version for testing. This version has very + limited memory resources: 64K of FLASH and 4K of SRAM. + + STATUS: The basic port was released in NuttX-6.5. This basic + port consists only of a "Hello, World!!" example that demonstrates + initialization of the OS, creation of a simple task, and serial + console output. The tiny SRAM limits what you can do with the + AT90USB647 (see issues below). + + * PJRC Teensy++ 2.0 AT9USB1286 + + This is a port of NuttX to the PJRC Teensy++ 2.0 board. This + board was developed by PJRC (http://pjrc.com/teensy/). The + Teensy++ 2.0 is based on an Atmel AT90USB1286 MCU with 128K + of FLASH and 8K of SRAM; a little more room to move than the + AT90USB647. + + STATUS: The basic port was released in NuttX-6.5. This basic + port consists of a "Hello, World!!" example and also slightly + simplified NuttShell (NSH) configuration (see the NSH User Guide + at http://www.nuttx.org/NuttShell.html). + + An SPI driver and a USB device driver exist for the AT90USB as + well as a USB mass storage configuration. However, this + configuration is not fully debugged as of the NuttX-6.5 release. + +AVR-specific issues. The basic AVR port is solid and biggest issue +for using AVR is its tiny SRAM memory and its Harvard architecture. +Because of the Harvard architecture, constant data that resides to +flash is inaccessible using "normal" memory reads and writes (only +SRAM data can be accessed "normally"). Special AVR instructions +are available for accessing data in FLASH, but these have not been +integrated into the normal, general purpose OS. + +Most NuttX test applications are console-oriented with lots of +strings used for printf and debug output. These strings are all +stored in SRAM now due to these data accessing issues and even the +smallest console-oriented applications can quickly fill a 4-8K +memory. So, in order for the AVR port to be useful, one of two +things would need to be done: + +1. Don't use console applications that required lots of strings. + The basic AVR port is solid and your typical deeply embedded + application should work fine. + +2. Create a special version of printf that knows how to access + strings that reside in FLASH (or EEPROM). + +NuttX-6.6 +--------- + +The 73rd release of NuttX, Version 6.6, was made on July 11, 2011 +and is available for download from the SourceForge website. The +6.6 release adds several smaller features but is mostly a bugfix +release. + +Bugfixes include + + * Fixed several NX Graphics bugs: Rendering fonts at >8 bits-per-pixel, + graphics move logic, and display artifacts that appear when a + window is closed. + * Corrections to the USB host mass storage class driver + * STM32 bugfixes: serial driver, GPIO interrupt handling + * LPC17xx: Changes for a success compilation with no console. + * Corrections to the Teensy AT90USB SD driver + * Changes for a clean compilation under the ZDS-II toolchain. + +Minor features: + + * Add logic to extract printf strings from FLASH (but there are + still printf issues for that target) + * Added a configuration for the Sure Electronics PIC32MX board. + However, higher priority tasks have stopped work on that + configuration. + * Added several new configurations for the STMicro STM3210E-EVAL + board. + * Added support for the STM3210E-EVAL board: (1) LCD in either + landscape or portrait mode, and (2) interrupting buttons. + * Added a configuration option to use different serial ports for + debug and for the NSH serial console (there are some issues + with CR-LF expansion and character echo if NSH is not run on + the console). + * Standardized the button press and button interrupt interfaces + so that they are common across all boards. + * Added a new graphics example that focuses on placing text on + the background while pop-up windows occur. Text should continue + to update normally with or without the popup windows present. + * Added ARM stack checking logic. + +See the ChangeLog for a detailed description of these changes. + +NuttX-6.7 +--------- + +The 74th release of NuttX, Version 6.7, was made on August 2, 2011 +and is available for download from the SourceForge website.

Add support for Composite USB drivers (in + particular for a CDC/ACM with MSC USB composite driver). + + Added a new RAM logging driver. This will allow debug output into + a RAM buffer associated with a character driver at /dev/ramlog. + Added the new command 'dmesg' to NSH that can be used to dump the + current contents of the log. This is useful for systems that do not + have the usual serial console (for example, if you only have a + Telnet console with NSH). + + * Networking: Add a lower level, primitive socket interface. Telnet + driver: + + A New Telnet daemon was created. It wraps a Telnet session within a + character driver that can serve as a "controlling terminal." The + Telnet session will then be inherited by tasks created from the + Telnet session and the stdin/stdout from the created task will + still go through the same Telnet connection. + + * STM32 Drivers. PWM driver pulse count was limited to 128; now is + (essentially) unlimited. Add support for (29-bit) extended CAN IDs. + Add support for I2C3. The SDIO driver is (mostly) verified on the + STM32 F4 platforms. + + * LPC17xx Drivers. Extended the CAN driver so that the TSEG1 and TSEG2 + bit times can be set via the NuttX configuration. Add support for + (29-bit) extended CAN IDs. + + * PIC32 Drivers. The PIC32 Ethernet driver is code complete (but still + untested). + + * FTPD. Add a new FTP server daemon. This is based loosely on + the hwport_ftpd library provided by Jaehyuk Cho. + + * Library: Add support for on_exit(). Implemented tcsetattr() and + tcgetattr(). Moved the old, too-smart fgets() to a new application + library function called readline(). Dumbed down the original fgets(). + Add strcasestr(), avsprintf(), inet_ntop(), and inet_pton(). + Add support to enable or disable debug output. + + * Build system: Support for building a 32-bit simulation executable on + a 64-bit Linux machine. Correct a dependency issue in the arch/*/src/board + directory. + +Bugfixes: + + * System: Correct PTHREAD_MUTEX_INITIALIZER + + * FAT: Fix an error in the FAT statfs() reported by David Sidrane. + + * STM32: Fix clock frequencies for APB2 timers. Correct AFIO register + offset. + + * PIC32. Correct GPIOs used for LEDs on the Sure PIC32MX board. + + * NSH.

Context switching support for the + Cortex-M4 FPU registers is now provided (in both "lazy" and "non-lazy" + modes) + + * General Drivers: Added a generic "upper half" Quadrature Encoder driver. + The USB CDC/ACM serial driver can now be dynamically connected or + disconnected from the host (programmatically or using NSH commands). + + * STM32 Drivers: Added a "lower half" Quadrature Encoder driver. + Verified the STM32 F4 DMA driver; Added F4 DMA support to the existing + STM32 SDIO driver. + + * STM32 Board Support. Added support for the STM32 F2 family and + for the STM3220G-EVAL board (contributed by Gary Teravskis). + Support is now included for C++ static constructors (verified using + the Atollic toolchain). Added support for the SRAM available on the + STM3240G-EVAL board. + + * PIC32 Drivers. PIC32MX USB (device) driver is now functional. + The PIC32MX Ethernet driver not yet fully verified (and an + unverified SPI driver is also available). + + * Networking. Added a lower-level, thread-independent socket layer. + Parts of this layer were created in 6.15 to support the FTPD + controlling terminal; this support has been extended in order + to support an NFS file system (not yet released). + + * NuttShell (NSH). NSH will now support a USB serial connection for + the console (such as CDC/ACM). This is useful in environments + where there is no physical serial port on the board. + + * Build System. Reorgnaization of networking header files. + +Critical Bugfixes. The following bug fixes are considered critical: + + * Networking: Fixed a "leak" in the TCP/IP read-ahead buffering logic. + Corrected an error in TCP/IP sequence numbering/ACK logic which + occurred when read-ahead buffering memory is exhausted. + + * STM32 Drivers: Fixed an buffer sizing error in the STM32 Ethernet + driver. + +Additional Bugfixes: Other important bug fixes are listed below. See +the ChangeLog of a complete, detailed list of bug fixes. + + * Networking: Corrected recv()/recvfrom() return value.

Note +that release consists of two tarballs: nuttx-6.17.tar.gz and +apps-6.17.tar.gz. Both may be needed (see the top-level nuttx/README.txt +file for build information). + +This release corresponds with SVN release number: r4607 + +New features and extended functionality: + + * Networking: Additional low-level, thread-independent socket + interfaces (for NFS client support). + + * RTC: Added a new interface call clock_synchronize(). This function + will reload the system time from an RTC and is required when the + system re-awakens from certain deep-sleep modes. + + * Graphics: Add NxConsole. This is a character device driver that + wraps an NX window and can be re-directed for stdout. This allows, + for example, a pop-up graphics window that contains a NuttShell (NSH) + session. A test of NxConsole is available at apps/examples/nxconsole. + + * Watchdog Drivers: Added an interface definition an "upper half" + driver to support watchdog timers. + + * Calypso: Support for TI Calypso-based cellphones (as supported by + the Osmocom-BB project) was contributed by members of the Osmocom-BB + team. This includes configurations for the Compal e88 and e99 phones. + + * USB Device Interface: Needed to extend the USB device interface + because there was no mechanism for passing endpoint OUT data that + may need to accompany a setup request. + + * STM32 drivers: Added some power management controls for entering + reduced power consumption states. An OTG FS driver was completed + and partially verified (this driver seems to be functional but since + it has been test so lightly, it might better be listed in the + next section "Work in progress"). + + * PIC32 drivers: The PIC32 Ethernet driver is now stable. The PIC32 + USB device controller driver is now functional (but not yet stable). + + * PIC32 boards: Added support for the Sure DB-DP11212 PIC32 General + Purpose Demo Board. There is now a PIC32 Starter Kit that + provides NSH only through a Telnet connection. + + * Build System: Some header files were moved into include/nuttx. + The goal is to move any non-standard header files to include/nuttx + or include/arch.

Both may be needed (see the top-level nuttx/README.txt +file for build information). + +This release corresponds with SVN release number: r4847 + +This release features new support for a Network File System (NFS) client. +This feature allows a tiny, embedded MCU to mount a remote file system +exported by an NFS server and then to access the file system as it would +any local file system. Then the tiny MCU can effectively have terabytes +of storage! + +This might be useful for data collection, for MCU configuration information, +for software updates, for providing modular, loadable code modes, controlling +a "farm" of MCUs, ... there are many possibilities and opportunities for +innovation! + +The NuttShell (NSH) now supports the following command: + + nfsmount + +That command will mount the remote NFS server directory at + on the target machine. is the IP address of +the remote server. + +The NFS development was the graduation project of Jose Pablo Rojas V. who +is a student at the Instituto Tecnolgico de Costa Rica (ITCR, or TEC). +A lot of effort went into understanding what a tiny, embedded NFS client should +do and getting the target resource usage to a bare minimum. Only around a +kilobyte or so of memory is required to run the NFS client (and most of that +for I/O buffers). Jose Pablo has spent several months living with NFS and +should be congratulated. + +Additional new features and extended functionality: + + * Drivers: SSD1289 LCD driver, MIO283QT2 LCD driver + + * LM3S: Additional register definition header files (contributed by Max + Neklyudov). + + * STM32 Boards: The STM32F4Discovery will now support an SSD1289 LCD, + The STM3220G-EVAL board support is now equivalent to the STM3240G-EVAL + board support. + + * PIC32 Boards: The Mikroelektronika PIC32MX7 MMB board port is now + functional, very complete, and stable. + + * Graphics: The NxConsole will now take keyboard input from the NX graphics + subsystem.

An address environment is the key notion underlying + "process" vs. tasks. If tasks are created with address environments + (by binfmt), the OS will propogate that environment to child threads + and will destroy the address environment when the "process" exists. + - If support for the PATH variable is enabled, the OS start up logic + will create an initial environment containing the default PATH + setting (CONFIG_PATH_INITIAL). This initial PATH will then be + inherited by all tasks. + + * Binfmt + + - The NuttX binary loaders have been updated to support the PATH + environment variable. Now, if the PATH is properly defined, programs + can be executed from mass storage using only the file name. This + feature is added to support more standard behavior (eventually, NSH + will support execution of programs in file systems by just entering + the file name, perhaps in 6.25?). + - The NXFLAT and ELF binary loaders have been extended to create + address environments for any new tasks executed from the file system. + This feature requires that the architecture support a memory management + unit (MMU) and the address environment interfaces declared in + include/nuttx/arch.h (currently, this is only supported by the z180). + + * Drivers: LCD driver for the Univision UG-2864AMBAG01 OLED + + * STM32: Support for STM32F100 high density chips contributed by Freddie + Chopin. + + * STM32 Drivers: Added optional RS-485 direction bit control (from + Freddie Chopin). + + * STM32 Boards: + + - Support for generic STM32F100RC board contributed by Freddie Chopin. + - stm32f4discovery/nxlines: STM32F4Discovery support for the + UG-2864AMBAG01 OLED. + - stm32f4discovery/winbuild: A version of the NuttX OS test + configured to build natively on Windows. + - stm32f4discovery/elf: Now uses the PATH variable to find ELF + executables. + - configs/cloudctrl: Added for Darcy Gong's CloudController board + + * PIC32 Boards: Update the Mirtool configuration for Release 2 of the + Mirtoo module. + + * Calypso: Add Calypso keypad driver. From Denis Cariki. + + * ZiLOG: + + - Add support for the z180 chip family and, specifically, for + the P112 retro hardware (see http://p112.feedle.net/). + - All ZiLOG configurations updated to use the current ZDS-II + and/or SDCC toolchains. + + * Graphics: + + - Add a semaphore handshake so that operations on buffers from + the NXMU client will be blocked until the NX server operates on the + buffer data (from Petteri Aimonen). + - nxtk_subwindowmove() and nxtk_getwindow(): Improvements to clipping + logic from Petteri Aimonen. + + * C Library: lib/ sub-directory renamed libc/ (there is a new lib/ sub- + directory that is used to hold all archives). + + * C++: Exception stubs from Petteri Aimonen. + + * Applications: + + - Add NSH hexdump command to dump the contents of a file (or character + device) to the console (contributed by Petteri Aimonen). + - Extend the NSH ifconfig command plus various DHCPC improvements + (from Darcy Gong). + + * apps/examples: + + - ostest: Replace large tables with algorithmic prime number + generation. This allows the roundrobin test to run on platforms + with minimal SRAM (Freddie Chopin). + - keypadtest: A new keypad test example contributed by Denis Carikli. + - elf and nxflat: If CONFIG_BINFMT_EXEPATH is defined, these examples + will now use a relative path to the program and expect the binfmt/ + logic to find the absolute path to the program using the PATH + variable. + + * Build system: + + - New top-level Makefiles: Makefile.unix and Makefile.win (along with + numerous changes to other make-related files). This adds basic + support for building NuttX natively under Windows from a CMD.exe + window (rather than in a POSIX-like environment). This build: (1) + Uses all Windows style paths, (2) Uses primarily Windows batch + commands from cmd.exe, with (3) a few extensions from GNUWin32. + + This capability should still be considered a work in progress + because: (1) it has not been verfied on all targets and tools, + and (2) still lacks some of the creature-comforts of the more + mature environments (like a function configure.sh script and + 'make menuconfig' support). + + - Example Windows native builds for STM32F4Discovery, eZ80, z16f, z8, + Z80, and Z180. + - Several configurations have been converted to work the kconfig- + frontends mconf configuration tool: stm32f4discovery/nxlines, and + all eZ80, z16f, z8, Z80, and Z180 configurations. + - Architectures now include a common Toolchain.defs file that can be + used to manage toolchains in a more configurable way (most of this + contributed by Mike Smith). + + * Build tools: + + - Renamed tools/winlink.sh to tools/copydir.sh. + - Several new tools/scripts to support the Windows native build: + tools/mkdeps.bat, tools/mkdeps.c, tools/link.bat, unlink.bat, and + copydir.bat. + - tools/incdir.sh and incdir.bat now support an -s option to generate + system header file paths. + - tools/b16.c: Fixed precision math conversion utility. + +Bugfixes (see the change log for details). Some of these are very important +(marked *critical*): + + * RTOS: Fix some backward conditional compilation in the work queue + logic (Freddie Chopin). + + * File System: Uninitialized variable caused assertions (from Lorenz + Meier). + + * Drivers: Partial fix for STM32 OTGFS device drivers and fix for short, + unaligned writes in the flash translation layer (drivers/mtd/ftl.c), + both from Petteri Aimonen. + + * STM32 Drivers: + + - Qencoder driver and TIM3 driver fixes from Ryan Sundberg. + - Fix timeout delay calculation in the STM32 OTG FS host driver. + + * LPC17xx Drivers: Resources not being properly released when I2C + driver is un-initialized. + + * Graphics: + + - Fix logic when the mouse drags outside of the window; fix + another "blocked message" handling case (both from Petteri Aimonen). + - nxtk_filltrapwindow(): Correct an offset problem (also from Peterri + Aimonen). + - nxglib_splitline(): Correct the "fat flat line" bug. + + * C Library: + + - nrand() changes to prevent coefficients from becoming zero which + would "lock up" the random number generate. + - Add rounding functions to the math library (contributed by Petteri + Aimonen). + + * Build system: Changes to MIN definitions in all limit.h header files + to avoid integer overflows. For example from (-128) to (-127 - 1) + (from Petteri Aimonen). + + * Applications: Modbus fixes from Freddie Chopin. + +As well as other, less critical bugs (see the ChangeLog for details) + +NuttX-6.25 +---------- + +The 92nd release of NuttX, Version 6.25, was made on February 1, 2013, +and is available for download from the SourceForge website.

This is not really a + useful feature and creates a violation of the OS layered + architecture. + + * Task Creation: + + - Implement a simple vfork(). In NuttX-6.25, this interface is + available only for ARM7/9, ARMv7-M (Cortext-M3/4), and MIPS32 + (PIC32MX) platforms. + - exec() now sets the priority of the new task to the same priority as + the parent task (instead of the arbirtrary value of 50). + - New, partially complient implementations of execv() and execl(). + These are only partially compliant because they do not overlay any + existing "process space" but rather create the new task and exit(). + - Add a complete implementation of posix_spawn(). This standard + interface is a better match for an MMU-less architecture than are + vfork() plus execv() or execl(). + - Add a task start hook that will be called before the task main + is started. This can be used, for example, to schedule C++ + static constructors to run automatically in the context of the + new task. + + * Task Parentage + + - Repartitioned tasking data structures. All shared resources are now + collected together in a "task group". A task group includes the + original task plus all of the pthreads created by the task. + - Added support for remember the parent "task group" when a new task is + started. + - Added optional support to record the membership of each thread in + the "task group". + - Implement support for retaining child task status in the "task group" + after the child task exists. This is behavior required by POSIX. + But in NuttX is only enabled with CONFIG_SCHED_HAVE_PARENT and + CONFIG_SCHED_CHILD_STATUS + - Add internal logic to "reparent" a task. This is useful, + for example, where the child task is created through a trampoline + task that redirects I/O. Reparenting allows the caller of posix_spawn() + to be reparented for the eventual child thread. + - Added support for SIGCHLD. Sent to all members of the parent task + group when the file member of the child task group exits. + - If SIGCHLD and retention of child task exist status are enabled, then + a more spec-compliant version of waitpid() is enabled. + - New interfaces waitid() and wait() are also enabled when SIGCHLD + is enabled. + + * File System + + - dup() and dup2() can new be used with opened files in a mounted file + system. This supports re-direction of output in NSH to files. + - The binfs file system was moved from apps/builtin to fs/binfs. The + binfs file system was extended to support execution of "builtin + applications" using exec(), execv(), execl(), or posix_spawn(). + - Added logic based on SIGCHLD to automatically unload and clean-up + after running a task that was loaded into memory. + + * Binary Formats + + - Much of the logic for "builtin applications" was moved from + apps/builtin to nuttx/binfmt/libbuiltin. Includes some extensions + contributed by Mike Smith. + - A binary loader was added for builtin applications to support + execution of "builtin applications" using exec(), execv(), + execl(), or posix_spawn(). + + * Drivers: + + - Added logic to marshal and serialized "out-of-band" keyboard + commands (such as cursor controls and key release events) intermixed + with normal ASCII keypress data. The encoding is partially integrated + in the HID keyboard driver and the decoding full integrated into the + apps/examples hidkbd and keypadtest (the latter contributed by Denis + Carlikli). + - Driver for the UG-2864HSWEG01 OLED contributed by Darcy Gong. + - Add support for removable serial devices (like USB serial). This + support is enabled by CONFIG_SERIAL_REMOVABLE. + + * ARMv7-M: + + - Added an option to use the BASEPRI register to disable interrupts + (instead of the PRIMASK). This eliminates some innocuous hardfaults + that interfere with some debug tools. You need to switch to the + BASEPRI method only if you have such tool interference. + + * STM32 Drivers + + - Bring STM32 F1 DMA capabilities up to par with the STM32 F2/F4 + (contributed by Mike Smith). + - Add support for USART single wire mode (Contributed by the PX4 + team). + - Updates to support for SPI DMA on the STM32 F1/F2/F4. From + Petteri Aimonen. + + * STM32 Boards: + + - New configuration to support the UG-2864HSWEG01 OLED on the + STM32F4Discovery board. + - Added a posix_spawn() test configuration for the STM32F4Discovery. + + * LM3S/LM4F + + - Files and directories repartitioned to support both LM3S and LM4F + using the STM32 organization as a model. + - Partial definitions for the LM4F contributed by Jose Pablo Carballo + (this is still a work in progress). + + * LM3S Boards + + - Added scripts and documentation to use OpenOCD with the LM3S (from + Jose Pablo Carballo). + + * LPC176x/LPC178x + + - Files and directories repartitioned to support both LPC175x/LPC176x + and the LPC177x/LPC178x families using the STM32 organization as a + model. The LPC1788 port is a work in progress by Rommel Marcelo. + + * LPC176x/LPC178x Boards: + + - Added a configuration to support the Wave Share Open1788 board. + This is still a work in progress by Rommel Marcelo. + + * LPC2148 Boards: + + - Add basic support for the The0.net ZP213x/4xPA board (with the LPC2148 + and the UG_2864AMBAG01 OLED). + - Add an nxlines configuration for the ZP213x/4xPA (with the LPC2148 + and the UG_2864AMBAG01). + + * Simulator: + + - Add an nxlines configuration for the simulator. + + * Networking: + + - Add logic to work around delayed ACKs by splitting packets + (contributed by Yan T.). + - Split net_poll() to create the internal interface psock_poll(). + + * LCDs: + + - Added support for LCD1602 alphanumeric LCD (HD4468OU controller). + + * Graphics: + + - Added 5x8 monospace font. This tiny font is useful for graph + labels and for small bitmapped display. Contributed by Petteri + Aimonen. + + * Build System: + + - Add an options to better manage toolchain prefixes. + - Redesigned how the context targer works in the apps/ directory. + The old design caused lots of problems when changing configurations + because there is no easy way to get the system to rebuild the + context. This change should solve most the problems and eliminate + questions like "Why don't I see my builtin application in NSH?" + + * Kconfig Files: + + - There are several new configurations that use the kconfig-frontends + tools and several older configurations that have been converted to + use these tools. There is still a long way to go before the conversion + is complete: + + configs/sim/nxwm + configs/sim/nsh + configs/stm3220g-eval/nxwm + configs/stm32f4discovery/posix_spawn + configs/olimex-lpc1766stk/nsh + configs/olimex-lpc1766stk/hidkbd + configs/olimex-lpc1766stk/nettest + configs/open1788/ostest + configs/stm32f4discovery/nsh + configs/stm32f4discovery/usbnsh + configs/lm326965-ek (all configurations) + configs/mcu123-214x/nsh + configs/ubw32/ostest + + * Tools: + + - tools/kconfig.bat: Kludge to run kconfig-frontends from a DOS shell. + - tools/configure.c: configure.c can be used to build a work-alike + program as a replacement for configure.sh. This work-alike + program would be used in environments that do not support Bash + scripting (such as the Windows native environment). + - tools/configure.bat: configure.bat is a small Windows batch + file that can be used as a replacement for configure.sh in a + Windows native environment. configure.bat is actually just a + thin layer that executes configure.exe if it is available. If + configure.exe is not available, then configure.bat will attempt + to build it first. + + * Applications: + + - New and modified examples: + + apps/examples/wlan: Remove non-functional example. + apps/examples/ostest: Added a test of vfork(). Extend signal + handler test to catch death-of-child signals (SIGCHLD). Add a + test for waitpid(), waitid(), and wait(). + apps/exampes/posix_spawn: Added a test of posix_spawn(). + + - NSH: + + NSH now supports re-direction of I/O to files (but still not from). + The block driver source argument to the mount command is now + optional for file systems that do not require a block driver. + NSH can now execute a program from a file system using posix_spawn(). + Added support for a login script. The init.d/rcS script will be + executed once when NSH starts; the .nshrc script will be executed + for each session: Once for serial, once for each USB connection, + once for each Telnet session. + + - Supports a new daemon that can be used to monitor USB trace outpout. + - Removed non-functional wlan example. + +Bugfixes (see the ChangeLog for details). Some of these are very important: + + * Tasking: + + - Fixed a *critical* task exit bug. Here is the failure scenario: + (1) sched_lock() is called increments the lockcount on the current + TCB (i.e., the one at the head of the ready to run list), (2) + sched_mergepending is called which may change the task at the head + of the ready-to-run list, then (3) sched_unlock() is called which + decrements the lockcount on the wrong TCB. The failure case that + I saw was that pre-emption got disabled in the IDLE thread, locking + up the whole system. + + * Signals: + + - sigtimedwait() would return a bad signal number if the signal was + already pending when the function was called. + + * Drivers: + + - Some SD cards will appear busy until switched to SPI mode for + first time. Having a pull-up resistor on MISO may avoid this + problem, but this fix from Petteri Aimonen makes it work also + without pull-up. + + * STM32 Drivers: + + - STM32 FLASH driver counting error (from Freddie Chopin). + - STM32 F4 maximum SPI frequency was wrong (corrected by Petteri + Aimonen). + + * STM32 Boards + + - Due to cloning of untested code, the logic to control on-board + LEDs did not work on any STM32 boards. + - Serial devices number /dev/ttyS0-5 is there is a serial console, + but /dev/ttyS1-6 if there is no serial console. + + * Binary Formats + + - C++ static constructors execute now using a start taskhook + so that they execute in the context of the child task (instead + of in the context of the parent task). + + * File Systems: + + - Several FAT-related bugs fixed by Petteri Aimonen. + + * Networking: + + - Fix poll/select issure reported by Qiang: poll_interrupt() must call + net_lostconnection() when a loss of connection is reported. Otherwise, + the system will not remember that the connection has been lost and will + hang waiting on a unconnected socket later. + - Similar issues corrected for recvfrom() and send(). + - Telnetd would hang in a loop if recv() ever returned a value <= 0. + + * Libraries: + + - fread() could hang on certain error conditions. + - Can't handle SYSLOG output to a character device from the IDLE task + (because the IDLE task can't block). + + * Build System: + + - Serial was driver was not being built if there is no console + device. Obviously, the serial driver may be needed even in + this case. + + * Additional Bugfixes: + + - sig_timedwait() and clock_time2ticks.c: Timing "rounding" logic + - ARM9 Compilation issue with low vectors. + - readline() return value + - Others as detailed in the ChangeLog: HID keyboard, LPC17xx bit + definitions, strndup(), PL2303, SYSLOG error handling, AT25, + apps/examples. + +NuttX-6.26 +---------- + +The 93rd release of NuttX, Version 6.26, was made on March 15, 2013, +and is available for download from the SourceForge website. Note +that release consists of two tarballs: nuttx-6.26.tar.gz and +apps-6.26.tar.gz. Both may be needed (see the top-level nuttx/README.txt +file for build information). + +This release corresponds with SVN release number: r5745 + +Note that all SVN information has been stripped from the tarballs. If you +need the SVN configuration information, you should check out directly from +SVN. Revision r5745 should equivalent to release 6.26 of NuttX: + + svn checkout -r5745 svn://svn.code.sf.net/p/nuttx/code/trunk nuttx-code + +Or (HTTP): + + svn checkout -r5745 http://svn.code.sf.net/p/nuttx/code/trunk nuttx-code + +Additional new features and extended functionality: + + * OS Initialization: + + - Add an additional call-out to support board-specific driver + initialization during the boot-up phase (available with + CONFIG_BOARD_INITIALIZE=y). + + * Tasking: + + - New interface task_spawn() that is like posix_spawn(), but uses + entry point addresses like task_create(). + - Additional data restructuring as a continuation of the task group + changes of NuttX 6.25. These data structures were moved from the + TCB structure into the task group: pthread join data, + atexit/on_exit callbacks, waitpid data structures, and message + queues. + - TCBs for tasks and pthreads are now separate structures. This + saves a little memory since tasks do not have to carry the overhead + for threads and vice versa. + + * Kernel Build: + + - Extensive changes were made to support the kernel build mode. In + this mode, NuttX is built as a monolithic kernel. NuttX is built + as a separate kernel mode "blob" and the applications are built + as a separate user mode "blob". The kernel runs in kernel mode and + the applications run in user mode (with the MPU restricting user + mode accesses). Access to the kernel from the user blob is only + via system calls (SVCalls). + - Extensive changes were made to the syscall, SVCall, and trapping + logic. Many internal interfaces were renamed. + - The memory manager was extended to support both kernel- and user- + mode allocations. Logic within the kernel needs to use the + correct kernel- or user-space allocator, depending upon the user + of the allocated memory. + - The user-space blob now contains a header built in at the beginning + of the block that provides the same information that was previously + provided by a kludgy, auto-generated header file (user_map.h). + - Basic support implemented for the ARMv7-M family with fragments + also implemetned for the ARMv6-M and MIPS32 families. + - Kernel build supported added for the LPC17xx Open1788 and for + the Atmel SAM3U-EK board. All testing is being performed on the + Open1788 board. + + * Signals: + + - Delivery of signals to threads within a task group is now compatible + with the way that signals are delivered to threads within a process. + + * Drivers: + + - Add a driver for the SST29VF NOR FLASH parts. + - USB device trace/debug feature extended to decode device-specific + trace events to make the trace output more readable (from Petteri + Aimonen). + - USB MSC device driver can not support names of differing sizes + in the USB descriptor and the SCSI fields (from Petteri Aimonen). + - Locking added to MMC/SD SPI drivers so that MMC/SD can co-exist on + the same bus as other SPI devices. Frequency is reset each time + that the MMC/SD SPI has the bus locked. (from Petteri Aimonen). + + * ARMv6-M (Cortex-M0): + + - Added support for the ARM Cortex-M0 family. + + * nuvoTon NUC120: + + - Added support for the nuvoTon NUC120 MCU (Cortex-M0). + + * nuvoTon NUC120 Boards: + + - Added basic support for the nuvoTon NuTiny-SDK-NUC120 board (Cortex-M0). + + * LPC17xx: + + - Added support for the LPC177x and LPC178x families. Most of this is + the work of Rommel Marcelo. + + * LPC17xx Boards: + + - Added support for Zilogic System's ARM development Kit, ZKIT-ARM-1769. + From Rashid. + - The port for the WaveShare Open1788 board is now functional. Basic + OS test and NuttShell (NSH) configurations are functional. More + driver development and testing is needed (from Rommel Marcelo). + + * LPC17xx Drivers: + + - Added an SD card MSI driver for the LPC178x. The driver is marginally + functional but requires DMA capability to be reliable. + + * STM32 + + - Support extended to handle the STM32 F3 family (Cortex-M4 with F1-like + peripherals). + + * STM32 Boards + + - Added support the STMicro STM32F3Discovery board (STM32 F3). + + * Stellaris LM3S/LM4F + + - Basic support for the LM4F120 family is in place, but untested (mostly + from Jose Pablo Carballo). + + * Stellaris LM4F Boards + + - Add support for the LM4F120 LaunchPad (untested). + + * Networking: + + - select() should now allocate a little less memory. + + * Memory Management: + + - Extended to support multiple heaps. This is used as part of + the kernel build in order to support separater user- and + kernel-mode heaps. + - The stand-alone memory manger test had to be removed. It + was too entangled and made extension of the memory manager + nearly impossible. This is a loss. + + * Build System: + + - Several configurations converted to use the kconfig-frontends + configuration tool. There are still many more that need to + be converted. + + * C Library: + + - Move the workqueue logic into the C library. There is now a + special user-space version of the work queue (which will only + be used with a NuttX kernel build). + - Implementation of itoa() contributed by Ryan Sundberg. + + * Applications: + + - The NSH builtin task logic now uses task_spawn() to start builtin + applications. + - The OS test now includes a test cased to verify task_restart(). + +Efforts In Progress. The following are features that are partially +implemented but present in this release. Most are expected to be fully +available in NuttX 6.27. + + * LM4F120 LaunchPad port. Code is in place, but nothing has been tested. + + * WaveShare Open1788 port. This port as actually complete and + functional. However, there is still ongoing development and + testing of drivers. + + * Kernel Build. Much progress has been made, but there kernel build is + not yet fully functional due to several user resources that are not yet + properly disentangled from the kernel blob. + + * Conversion of old configurations to use the kconfig-frontends + tool is an ongoing effort that will continue for some time. + +Bugfixes (see the ChangeLog for details). Some of these are very important: + + * Tasking: + + - The wrong PID was being signalled with SIGCHILD. It should be + the PID of the task that create the task group, not the ID of + the last thread to leave the task group. + - Added logic so that some internal resources and states are recovered + when tasks are deleted or restarted. Handle cases where there are + outstanding timed events pending when tasks are deleted or restarted. + + * ARMv7-M: + + - Several fixes to the MPU control logic. + + * Drivers: + + - Removable serial drivers race conditions fixed. + - MAX11802 timing bug (from Petteri Aimonen). + + * STM32 Drivers: + + - Handle cases were SPI DMA logic fails if sem_wait is awakened + by a signal. Need to clear error flags to prevent corruption of + subsequent transfers. Also, bit count should not be changed while + the SPI peripheral is enabled (from Petteri Aimonen). + - Fixes to the OTG FS device driver from Petteri Aimonen. + - Fix typos in DMA register header file (from Yan T.) + + * Graphics: + + - Correction to the hyphen in the SANS 17x22 font (from Petteri + Aimonen). + + * Networking: + + - Corrected errors in the socket poll/select logic. Additional + state logic was needed to detect if the socket is still connected + before starting the poll wait. (bug reported by Qiang Yu). + + * Memory Management: + + - mallinfo() should hold the memory manager semaphore (from Petteri + Aimonen. + + * Build System: + + - Resolved several build errors reported by Mike Smith. + + * Applications: + + - Fixed an NSH memory leak: Needed to detach after creating each + pthread. + - readline() now returns EOF on any failure (instead of a negated + errno value). This is because the underlying read is based on + logic similar to getc. The value zero (meaning end-of-file) + was being confused with a NUL. So if a NUL was received, the + NSH session would terminate because it thought it was the end of + file. + +NuttX-6.27 +---------- + +The 94th release of NuttX, Version 6.27, was made on April 28, 2013, +and is available for download from the SourceForge website. Note +that release consists of two tarballs: nuttx-6.27.tar.gz and +apps-6.27.tar.gz. Both may be needed (see the top-level nuttx/README.txt +file for build information). + +Additional new features and extended functionality: + + * OS Initialization: + + - Add missing registration of /dev/zero. Registration of /dev/null + should depend upon conditional compilation. From Ken Pettit. + + * Tasking: + + - Added a new interface to set aside memory on the task's stack. This + is used (at least in the kernel build) to hold task arguments. + - Remove up_assert_code(). One assertion routine is enough. + + * Kernel Build: + + - Extensive changes were made to support the kernel build mode. In + this mode, NuttX is built as a monolithic kernel. NuttX is built + as a separate kernel mode "blob" and the applications are built + as a separate user mode "blob". The kernel runs in kernel mode and + the applications run in user mode (with the MPU restricting user + mode accesses). Access to the kernel from the user blob is only + via system calls (SVCalls). + - Kernel build configurations for the Open1788 board and for the + STM32F4Discovery now execute correctly. + - Changes were made to task and thread start-up routines, signal + handling, data structures, ARMv7-M SVCalls, stack management + interfaces, + + * Drivers: + + - Driver for the ST7567 LCD Display Module from Univision Technology + Inc. Contributed by Manikandan.S + - SPI initialize functions renamed so that multiple SPI blocks can + be initialized. + - Extended to support the RAMTRON FM25V01 device. Contributed by + Lorenz Meier + - Serial drivers: TIOCSERGSTRUCT ioctls now conditioned on + CONFIG_SERIAL_TIOCSERGSTRUCT + + * ARMv7-M (Cortex-M3/4): + + - Added support for modifiable interrupt vectors in RAM + + * nuvoTon NUC1xx: + + - Added kernel build support + + * Freescale Kinetis: + + - Add kernel build support + - Add support for the Kinetis L family of Cortex-M0+ MCUs. Contributed + by Alan Carvalho de Assis. + + * LPC17xx: + + - Now holds off sleep mode in the IDLE loop is DMA is in progress + (because sleep mode will disable CPU SRAM). + + * LPC17xx Boards: + + - ZKIT-ARM-1769: Now supports the ST7567 LCD display module. Added + an nxhello configuration for testing (Manikandan.S). + - ZKIT-ARM-1769: Add support for both CAN1 and CAN2. Contributed by + M.Kannan + + - Open1788: Basic support for the WaveShare Open1788 board is complete + with working OS test, NSH, and graphics configurations. + - Open1788: Integrated the LPC178x LCD driver with the WaveShare display. + Touchscreen support is included, howerver, there appears to be an + issue with the Open1788 touchscreen interrupt signal. + - Open1788: Now supports SDRAM (used to provide the LCD framebuffer). + - Open 1788: Reversed sense of the IDLE LCD. It is now off when the + LPC17 is sleeping and on when awake. That is much a better visual + indication of the dynamic CPU load + + * LPC17xx Drivers: + + - Added an LCD framebuffer driver for the LPC177x/8x family. + - Implemented LPC17xx GPDMA support. + - Integrated the LPC17xx GPDMA support into the SD card driver. + - SSP driver adapted to work with the LPC178x family. + - Separate LPC176x and LPC178x GPIO logic; this logic is too different + to maintain in one file with conditional compilation. + - Re-design of the GPIO logic for the LPC178x family by Rommel Marcelo. + + * LPC43xx: + + - Added kernel build support + + * STM32: + + - Added support for kernel mode build. + - Added architecure support for the STM32 F427/F437 chips. Contributed + by Mike Smith + + * STM32 Boards: + + - Added a configuration to support a kernel mode build of the OS test + on the STM32F4Discovery + + * Stellaris LM3S/LM4F: + + - Added kernel build support + - Added support for the 7 UARTs on the LM4F120 + + * Stellaris LM4F Boards: + + - Added scripts and instructions to simplify use of OpenOCD with ICDI + (JP Carballo) + - The basic for the Stellaris LM4F120 Launchpad is complete. This + includes support for OS test and NSH configurations. Additional + driver development is needed. + + * Build System: + + - Directories where the same sources files are used to build different + objects in the first and second pass kernel builds need to keep those + objects in separate directories so that they are not constantly + rebuilt. + + * Applications: + + - apps/system/ramtest: Add a simple memory test that can be built + as an NSH command. + + * Tools: + + - kconfig2html is a new tool which will replace the hand-generated + documentation of the NuttX configruation variables with auto- + generated documentation. + +Efforts In Progress. The following are features that are partially +implemented but present in this release. Most are expected to be fully +available in NuttX 6.28. + + * A port to the Freescale Freedom KL25Z is complete but not yet stable + enough. The KL25Z is a low-cost Cortex-M0+ part with 128KB of FLASH + and 16KB of SRAM. This is is the effort of Alan Carvalho de Assis. + + * Conversion of old configurations to use the kconfig-frontends + tool is an ongoing effort that will continue for some time. + At this time, only 32% of the configurations have been converted + to use the kconfig-frontends tools. + +Bugfixes (see the ChangeLog for details). Some of these are very important: + + * Tasking: + + - Fixed a critical bug: When there is pending C buffered output + and the system is very busy, the a pthread may be blocked at + a critical point when trying to exit. Blocking at this critical + point would cause crashes. All entire task/thread exit logic + paths were reviewed and failsafe mechanisms were put in place + to assure that exitting tasks never block after task teardown + has been started. + + * ARMv6-M: + + - Fixed parameter passing for all system call inline functions with > 3 + parameters + - Fixed a major problem: The Cortex-M0 has no BASEPRI register but the + logic of NuttX-6.26 was using it to manage interrupts. Switch to + using the PRIMASK instead. This means that hardfaults will (again) + occur when SVC instructions are executed + + * ARMv7-M: + + - Corrected Correct MPU sub-region settings for unaligned regions. + - In exception handling with CONFIG_NUTTX_KERNEL, need to explicitly + set and clear the privilege bit in the CONTROL + - Fixed parameter passing for all system call inline functions with > 3 + parameters + + * Drivers: + + - Support for O_NONBLOCK was not supported in the "upper half" + serial driver. + - PL2303 compilation errors + + * Stellaris LM3S/4F: + + - Corrected typos in alternate function definitions. + + * LPC17xx Drivers: + + - Added a work-around for an ADC errata. From Chris Taglia + - Only one ADC pin was configured. Need to configure all that + are in the ADC0 set. From MKannan + + * File Systems: + + - The FAT logic was not making a distinction between directory + non-existence and file non-existence so when it you try to + create a file in a non-existent directory, it would create a + file with the name of the missing directory. Reported by Andrew + Tridgell + - Several fixes to the FAT file system from Ronen Vainish. These + fixes mostly involve the logic to extend directory clusters for + the case of long file names but also include a few important + general fixes (such as for storing 32 bit FAT values) + - mkfatfs was writing the boot code to the wrong location. From + Petteri Aimonen + + * Networking: + + - Fixed a compilation error when socket options are are disabled. + Reported by Daniel O'Connor + + * C Library: + + - Corrected an error in sscanf. If %n occurs in the format statement + after the input data stream has been fully parsed, the %n format + specifier will not be handled. Reported by Lorenz Meier + - strchr(str, '\0') should return a pointer to the end of the string, + not NULL. From Petteri Aimonen + + * Build System: + + - Fix naming of NuttX target if EXEEXT is defined. + + * Applications: + + - OS test: Fix timing error in non-cancelable thread test. + - NSH: Correct the test of the skip input parameter. Was limiting the + range to <= count.

Note +that release consists of two tarballs: nuttx-6.28.tar.gz and +apps-6.28.tar.gz. Both may be needed (see the top-level nuttx/README.txt +file for build information). + +Additional new features and extended functionality: + + * File Systems: + + - SMART FLASH file system (contributed by Add Ken Pettit). + + * MTD (FLASH) Drivers: + + - Add support of MTD partitions via a new MTD driver that manages a + set of MTD devices, each managing a subset of the FLASH region + managed by the parent MTD driver. + - Extended the MTD interface to provide an (optional) method to + perform byte oriented writes if supported by the FLASH part. + - M25Px driver re-architected to use the byte write capability (when + possible) and to use 4KB sectors for the erase block size when the + part supports it (from Ken Pettit). + + * LCD Drivers: + + - New interface definitions to support audio devices (from Ken Pettit) + and alphanumeric, segment LCDs. + + * Wireless Drivers: + + - Added new driver for the wireless nRF24L01+ transceiver (from + Laurent Latil). + + * Calypso: + + - Added support for the Pirelli DP-L10 phone (from Craig Comstock via + Alan Alan Carvalho de Assis) + + * STM32: + + - Added an option to conditionally disable the "wfi" sleep mode. This + is needed with certain JTAG debuggers to prevent the debug session + from being disconnected (from Ken Pettit). + - Added support for the STM32L (STM32L15X/STM32L16x) family. + - Added STM32F103C4 and F103C8 chip support (from Laurent Latil). + - Added a new interface function, stm32_dmacapable() that can be used + to determine if DMA is possible from the specified memory address + (from Petteri Aimonen) + + * STM32 Drivers: + + - If CONFIG_STM32_DMACAPABLE is defined, the STM32 SPI driver now uses + stm32_dmacapable() to determine if it is possible to perform DMA + from the specified address. This change is important for the STM32 + F4 which may have SPI data buffers allocated on the stack in CCM + memory which cannot support the DMA (from Petteri Aimonen). + + * STM32 Boards: + + - Support added for the MikroElektronika Mikromedia for STM32F4 + development board (from Ken Pettit) with the MIO283QT2 LCD and + touchscreen. Several graphics configurations are included. + - The HY-mini STM32v board now uses the common SSD1289 driver + and supported the card detect interrupt. Several new + configurations also added and some removed (from Laurent Latil). + - Support added for the R65105-based LCD that comes with some + HY-Mini STM32v boards (from Christian Faure). + - Added basic support for the STM32L-Discovery board. Drivers + for the on-board segment LCD are included. + - Added support for the STM32 Tiny development board based on the + STM32 F103C8T6 MCU. This includes support for the nRF24L01+ + wireless on the board (from Laurent Latil). + + * Stellaris LM3S/LM4F: + + - Support added for a TI/Stellaris internal FLASH MTD driver (from Max + Holtzberg). + + * Stellaris LM4F Boards: + + - The LM3S6965-EK now has configurations for the UDP discovery tool and + for the TCP echo server (both from Max Holtzberg) + + * Atmel ATSAM3/4: + + - Reorganized, renamed, and updated directory structure to better + support additional members of the SAM3/4 family. + - Added support for both the ATSAM4S and ATSAM4L families. The + ATSAM4S is similar to the ATSAM3U, but the ATSAM4L is quite a + different beast, really much more akin to the AVR32s SoCs but + with a Cortex-M4. + + * Atmel ATSAM3/4 Boards: + + - Added support for the Atmel SAM4L Xplained Pro development board. + This board features the ATSAM4LC4C MCU (Cortex-M4 with 256KB FLASH + + 32KB SRAM). + - Added support for the Atmel SAM4S Xplained developement board. This + board features the ATSAM4S16C MCU (Cortex-M4 with 1MB FLASH + 128KB + SRAM). + + * PIC32MX Boards: + + - Added support for the 1602 segment LCD on-board the Sure PIC32MX + board. This board will now also support a USB NuttX console and + the USB monitor test program. + + * Build System: + + - Clean-up of almost all .gitignore files: Made scope of ignore to be + only the current directory; Ignore .dSYM files in directories where + .exe's may be built. Also, in Makefiles, clean .dSYM files in + directories where an .exe may be built. + - Standardize and consolidated all build-as-an-NSH-application + configuration settings. Now only CONFIG_NSH_BUILTIN_APPS is + sufficient to build an application, test, or or example as an NSH + builtin application. + - Added support for a generic ARM, ARMv6-M and ARMv7-M Windows EABI + toolchains. + + * Libraries: + + - Added encoder/decoder logic to marshal and serialize special segment + LCD (SLCD) commands intermixed with normal ASCII data. This is the + similar to the encoding/decoding logic that is used to marshal + special commands from a keyboard. + - Add dprintf() and vdprintf() (the latter from Andrew Tridgell). + - Add an application that may be built as an NSH builtin command that + will erase FLASH using a flash_eraseall NSH command (from Ken Pettit). + + * Applications: + + - Added an MTD partition test/examples. Currently used with (1) the a + simulation configuration to test MTD partitions on a RAM emulation + of FLASH and (2) with the Mikroe STM32F4 configuration. + - Added a test/example to verify alphanumeric, segment LCDs. + - Added a simple single threaded, poll based TCP echo server based + on W. Richard Stevens UNIX Network Programming Book (from Max + Holtzberg). + - Added several tests of the SMART block driver and file system (from + Ken Pettit). + - Added a runtime configuration for the UDP discover utility (from + Max Holtzberg). + - Added an example application to demo the nRF24L01 driver (from + Laurent Latil). + - New and modified NSH commands: + Added a -h option to the df command to show the volume information + in human readable form (from Ken Petit). + Add a new mksmartfs command (from Ken Petit). + +Efforts In Progress. The following are features that are partially +implemented but present in this release. Most are expected to be fully +available in NuttX 6.28. + + * Audio System: + + - A complete audio subsystem include CODECs, higher level management, + interface definitions, and audio drivers was contributed by Ken + Pettit. This work has not been completely verified as of this + release and so is categorized as a work-in-progress. At present, + progress is blocked due to issues interfacing with the VS1053 + audio DAC on the Mikroe STM32F4 board. + + * kconfig-fronted Configuration: + + - Conversion of old configurations to use the kconfig-frontends + tool is an ongoing effort that will continue for some time. + At this time, only 43% of the configurations have been converted + to use the kconfig-frontends tools. + +Bugfixes (see the ChangeLog for details). Some of these are very important: + + * Tasking: + + - Modify assertion in the priority inheritance logic that is reported + to cause false alarm assertions. + + * Kernel Build: + + - Typo in syscall proxying logic corrected by Ken Pettit. + + * Networking: + + - Poll setup/teardown logic should ignore invalid (i.e., negative) + file descriptors (from Max Holtzberg). + - When readahead data is available, the network poll() logic should + set POLLIN (or POLLRDNORM), not POLLOUT (from Max Holtzberg). + + * LCD Drivers: + + - Correct power controls in the MIO283QT2 LCD driver. + + * USB Device Controller Drivers: + + - Change the default IN request buffer size from 64 to 96. This will + avoid requests of exactly MAXPACKET size and, hence, avoid so many + NULL packets. Also, fix the OUT request buffers size to exactly the + max packet size. It really cannot be any other size. + + * STM32 Drivers: + + - Correct some bad STM32 F1 DMA definitions that crept into the system + a few months ago a broke STM32 F1 DMA (from Laurent Latil) + - Fixed an error in NULL packet handling in the STM32 F1 USB device + controller driver: If the NULL-packet needed flag ever got set, + then it was not being cleared and infinite NULL packets resulted. + This only affects the CDC/ACM class and was the cause of the + failures using the USB CDC/ACM device as a NuttX console. With this + change the USB works well as an alternative NuttX console device for + the STM32 F1 family. + - Correct some bad condition compilation in the RCC logic (CONFIG_ + missing from setting names). This affects some STM32 FLASH pre- + fetch settings (from Lorenz Meier). + - Change for hardware flow control support for STM32. The change also + fixes incorrect operation of USART2 and UART5 in current master + (from Lorenz Meier and Mike Smith). + - Fixed a backward conditional in USB OTG FS host controller driver + that prevented detection of disconnection events (from Scott). + + * LPC17xx Drivers: + + - I2C interrupt control. Also correction for a single byte read + timeout error (from M. Kannan). + + * Freescale Kinetis: + + - Freedom KL25Z pin multiplexing and LED control corrections (from + Alan Carvalho de Assis) + + * PIC32MX: + + - Fix NULL packet handling in the PIC32 USB device driver. Without + this fix the CDC/ACM driver cannot be used reliably with the PIC32 + USB. With this change the USB works well as an alternative NuttX + console device. + + * Graphics: + + - Default priorities for NxWidget and NxWM threads should be 100, + not 50, to be consistent with other default priorities. + + * Applications: + + - Remove the CONFIG_EXAMPLES_NXTEXT_NOGETRUN option from the NXTEXT + example. The test logic was bad for the case where this options is + not selected. Also, completed the empty Kconfig file. + - C++ name mangling was occurring when this example is built as an NSH + built-in application causing the entry to be undefined when called + from C code. + - Add some missing NSH library configuration values (from Lorenz + Meier). + +NuttX-6.29 +---------- + +The 96th release of NuttX, Version 6.29, was made on July 31, 2013, +and is available for download from the SourceForge website. Note +that release consists of two tarballs: nuttx-6.29.tar.gz and +apps-6.29.tar.gz. Both may be needed (see the top-level nuttx/README.txt +file for build information). + +Additional new features and extended functionality: + + * Drivers: + + - Generalized the SSD1306 driver and added support UG-2832HSWEG04 + which is very similar to the existing support for the + UG-2864HSWEG01. + - Added support for a generic bit-bang SPI driver. This includes + both a common "upper half" driver as well as a platformp-specific + "lower half" dirvers based on a common "template." + + * ARMv7-A, Cortex-A5 + + - Added support for the ARMv7-A architecture and the Cortex-A5 in particular. + + * ARMv7-M, Cortex-M3/4 + + - Modified how some registers are copied during a context switch (with + lazy FPU register saving). This should save some context switching + time when the context switch is due to interrupt level processing. + + * STM32: + + - Added support for a separate CCM heap. This may be useful for + segregating allocations for CCM (which cannot be used for DMA) + from other allocations (that may be used used for DMA). + + * STM32 Drivers: + + - DAC: Added support for DAC DMA (contributed by John Wharington). + - I2C: An I2C driver for the STM32 F3 family (from John Wharington). + + * Atmel AT91 SAM/4: + + - Add support for SAM3X and SAM3A chips + + * Atmel AT91 SAM/4 Drivers: + + - Re-architect the SAM3/4 SPI driver so that is it compatible with the + SPI drivers of other MCUs. + - Added register definition file for the SAM4L LCD peripheral. + - Added SAM4L PDCA register definition file + + * Atmel AT91 SAM/4 Boards: + + - SAM4L-Xplained: Added support for the SPI-based SD card on the I/O1 + module. + - SAM4L-Xplained: Added a driver for the LED1 segment LCD module. + - SAM4L-Xplained: Added support for the UG-2832HSWEG04 OLED on the + SAM4L Xplained Pro's OLED1 module + - SAM4S-Xplained: Added support for on-board 1MB SRAM + - Arduino Due: Basic support for the Arduino Due (SAM3X) is now + included. + - SAM3U-EK: The touchscreen is now functional. + + * Atmel AT91 SAMA5D3 + + - Added support for the Atmel AT91SAMA5D3 Cortex-A5 chip family. + + * Atmel AT91 SAMA5D3 Boards + + - Added support for the Atmel SAMA5D3x-EK boards which use the AT9 + SAMA5D3x chips (x=1,3,4,5). + + * Freescale KL25Z Drivers + + - Freescale KL25Z TSI register definitions and example TSI driver for + the Freedom KL25Z board from Alan Carvalho de Assis. + - Added SPI driver and register definitions for the Freescale KL25Z. + - Added a framework for controlling SPI-related discrete inputs and + outputs. Taken from work by Alan Carvalho de Assis + + * Build System: + + - New sub-directories to hold SPI-related files: includes/nuttx/spi.h + moved to include/nuttx/spi/.; SPI-related Kconfig info moved from + drivers/Kconfig to drivers/spi/kconfig. + - Finally... I changed the naming of configuration variables like + CONFIG_DRAM_ to CONFIG_RAM_. This has bothered me for a long time + since most boards don't have DRAM. The more generic RAM naming + should not produce so much cognitive dissonance + + * Libraries: + + - Added CRC16 support. + + * Applications: + + - Added Zmodem file transfer support. This may be used as an embedded + library or may be built as 'sz' and 'rz' commands that can be + executed from NSH. + - C++ initializers should be set once and, preferably, in the context + of the task that uses any C++ statically initialized classes. This + only becomes an issue if cxxtest or helloxx are built as NSH builtin + applications. Then you want the initialization done in cxxtext or + helloxx and not in NSH (and certainly not twice). Added + configuration options to control who does the C++ initialization. + NSH now does not do C++ initialization be default and must be + configured to do otherwise. Conversely, cxxtest and helloxx + will always do C++ initialization unless configured do otherwise. + - examples/cxxtext: Add ostream test as provided by Michael. + - NSH: Added a 'cmp' command that can be used to compare two files + for equivalence. Returns an indication if the files differ. + Contributed by Andrew Tridgell (via Lorenz Meier). + +Efforts In Progress. The following are features that are partially +implemented but present in this release. They are not likely to be +completed soon. + + * Audio System: + + - A complete audio subsystem include CODECs, higher level management, + interface definitions, and audio drivers was contributed by Ken + Pettit. This work has not been completely verified as of this + release and so is categorized as a work-in-progress. At present, + progress is blocked due to issues interfacing with the VS1053 + audio DAC on the Mikroe STM32F4 board. + + * kconfig-fronted Configuration: + + - Conversion of old configurations to use the kconfig-frontends + tool is an ongoing effort that will continue for some time. + At this time, only 45% of the configurations have been converted + to use the kconfig-frontends tools. + +Bugfixes (see the ChangeLog for details). Some of these are very important: + + * File Systems: + + - Fixed compilation error if no file systems are enabled: Change + error to ERROR. + - Read-Ahead/Write buffering: Correct typos that can cause failures + in some configurations (From Chia Cheng Tsao). + + * Drivers + + - Remove the wait for the touchscreen busy bit in the ADS7843E driver. + From my reading of the ADS7843 spec, it would not be appropriate to + wait for the BUSY bit to de-asserted anyway (since it is only de- + asserted when we read the data). Most boards do not even bother to + provide the BUSY bit. + - MMC/SD SPI based driver: Driver needs to make sure that the SPI + mode and data width are correct. + - ENC28J60: Change buffer ordering to work around Errata. From Dave + (ziggurat29). + + * USB Device Controller Drivers: + + - Fixed a typo in the composite device driver unitialization logic. + DEV1 should be DEV2 in one case. + - usbdev.h: Fix some typos that cause compiler errors when + CONFIG_USBDEV_DMA and CONFIG_USBDEV_DMAMEMORY are selected (From + Chia Cheng Tsao). + + * ARM9: + + - Fix a bug (uninitialized register error) that crept in the ARM9 + boot-up code several years ago. Obviously no one has used the + ARM9 NuttX port for years! + + * STM32 Drivers: + + - Fix STM32 OTF FS endpoint allocation logic. Apparently the same + endpoint can be allocated as both an IN or an OUT endpoint. The + existing implementation only supported one allocation, either IN or + OUT. This resulted in failures to allocate endpoints when used with + the CDC/ACM + MSC composite driver (From Chia Cheng Tsao). + - SDIO: Add support for the data block end (DBCKEND) interrupt to + terminate transfers (From Chia Cheng Tsao). + - DAC: Fixed numerous DAC driver errors and added support for DAC + DMA (contributed by John Wharington). + + * SAM3/4: + + - SAM4S: Correct configuration of PIO pins for SAM4S B and C peripherals. + - Need to disable write protection before configuring PIO pins. + - GPIO configuration logic must protect against re-entrancy. + - Clocking must be applied to the SMC module for the 3X and 3A family in + order for the NFC SRAM to be functional. + - Fixed some errors for interrupts on ports D-F. + + * SAM3/4 Drivers: + + - Common SPI driver: Fix SPI mode setting. In the SAM3/4 family, the + clock phase control (CPHA) is inverted (NPHA). Also fixed an + incorrect pointer test. Was checking if the wrong pointer was NULL. + + * SAM3/4 Boards: + + - SAM3U-EK: Fix polarity of the /PENIRQ signal (it is active low). + The SAM3U-EK board now runs at 96MHz. + + * Applications: + + - apps/examples/nxhello: Minor fix for compilation error when the + display resolution is low (< 8bpp) due to a typo that has been there + for a long time. Also Correct default colors when in Y1 code mode. + - apps/system/ramtest: The RAM test was not correctly built + into the configuration and build system. + - apps/examples/composite: Change to prevent some false alarm debug + assertions (From Chia Cheng Tao). + +NuttX-6.30 +---------- + +The 97th release of NuttX, Version 6.30, was made on September 14, 2013, +and is available for download from the SourceForge website. Note +that release consists of two tarballs: nuttx-6.30.tar.gz and +apps-6.30.tar.gz. Both may be needed (see the top-level nuttx/README.txt +file for build information). + +Additional new features and extended functionality: + + * Common Drivers: + + - Extended TERMIOS support for serial and CDC/ACM drivers. From + Mike Smith, Andrew Tridgell and Lorenz Meier. + - Added option to disable serial port reordering. From Lorenz Meier. + - Several changes to the USB host control interface and extensions to + common USB host logic to handle host controllers with multiple + downstream ports in the root hub. + - USB device tracing: Extended decoding and stringifying of USB trace + output to include trace output from class drivers. + - USB host tracing: Added support for USB host tracing similar in + some ways to USB device tracing: Stringification is an inherent + part of the trace decoding (not an option). Only available in the + SAMA5 USB host drivers now. + + * Networking / Network Drivers + + - Support for the Microchip ENCX24J600 Ethernet driver from Max + Holtzberg + - CC3000 Networking. Initial support for the TI CC3000 network + module on the Freescale Freedom-KL25Z board from Alan Carvalho + de Assis. This is still a work in progress. + + * ARMv7-A, Cortex-A5 + + - Restructured some MMU-related logic and header files. + - Hooks added for Cortex-A8, but not yet used. + + * STM32 Drivers: + + - STM32 SPI: nbits() interface extended to control bit order as well + as bit width (from Teemu Pirinen) + + * STM32 Boards + + - Olimex STM32-P107: Incorporate ENCX24J600 networking for the Olimex + STM32 P107 board. + - LeafLabs Maple Board: Add board support for the LeafLabs Maple and + Maple Mini boards. From Librae. + + * Atmel AT91 SAMA5D3x + + - Added support for the SAMA5 DMAC controllers. + - DMA-capable drivers for the SAMA5 SPI peripherals. + - DMA-capable HSCMCI 0/1/2 drivers. + - Support for PIO interrupts + - Utilities for intelligent conversions between physical and virtual + addresses. + - Added USB host controller drivers for both the OHCI (low- and full- + speed) peripheral and the ECHI (high-speed) peripheral. + - Added USB device controller for the SAMA5 UDPHS peripheral (full- + and high-speed). + - Added a Two Wire (TWI) driver. This is a variant of I2C. + + * Atmel AT91 SAMA5D3x-EK Development Boards + + - Now supports onboard SDRAM. Modified heap initialization logic + to include SDRAM if configured. + - Integrated a FAT file system on the on-board SPI-based AT25 serial + FLASH + - Integrated HSMCI0 and HSMCI1 support for the microSD and full file + SD card slots. Includes PIO interrupts for card detection events. + - Integrated USB OHCI and ECHI host and high-speed peripheral support. + File system on AT25 now exported via Mass Storage Class. Includes + PIO VBUS controls. + - Integrated the TWI driver and the I2C tool. Added support for an + external AT24 serial EEPROM. + + * Applications: + + - apps/examples/cc3000. Initial support for the TI CC3000 network + module on the Freescale Freedom-KL25Z board from Alan Carvalho de + Assis. Includes the test to verify the CC3000. + - apps/examples/usbmsc: apps/examples/usbstorage renamed usbmsc for + consistency. Change submitted by CCTSAO. + - apps/system/usbmonitor: The USB monitor has been extended so that + it can be used with USB device or host trace data. + +Efforts In Progress. The following are features that are partially +implemented but present in this release. They are not likely to be +completed soon. + + * CC3000 Networking + + - CC3000 Networking. Initial support for the TI CC3000 network + module on the Freescale Freedom-KL25Z board from Alan Carvalho + de Assis. This is still a work in progress. + + * kconfig-fronted Configuration: + + - Conversion of old configurations to use the kconfig-frontends + tool is an ongoing effort that will continue for some time. + At this time, only 46% of the configurations have been converted + to use the kconfig-frontends tools. + +Bugfixes (see the ChangeLog for details). Some of these are very important: + + * File Systems: + + - ROMFS: Fix an error where long (>15) file names were read + incorrectly from a ROMFS file system. From Mike Smith + - NXFFS: Clean up some compiler warnings. + + * Common Drivers + + - MMC/SD driver: Correction for a bad return value when multiple + block SDIO transfers are suppressed. By Andrew Tridgell. + - USB HID keyboard and mass storage host-side class drivers: Fix some + compilation errors and warnings when pre-allocated data structures + are used. + - USB device-side class drivers: Fix some compilations errors when + DUALSPEED (i.e., full- and high-sped) support is enabled. + - CDC/ACM and PL2303: Don't use max packetsize assigned to the endpoint + when allocating request buffers; The default value of the endpoint + max packetsize may be incorrect because the endpoint has not yet + been configured. Really only an issue for high-speed endpoints. + - USB Host Mast Storage Class: Fixed a problem that was causing some + devices to fail to initialize: If device is returning fatal transfer + errors while attempting to initialize, don't bother with the startup + retries; abort immediately so that the device will be reset and we + can try again with a better ready device. + - USB Host Mast Storage Class: Correct a reference counting error: + When an MSC device transfer fails while waiting for UnitTestReady, + the reference count on the class was not being decremented. The end + result is a memory leak as can be seen by the USB device numbers + incrementing: sda, sdb, sdc, ... + - USB Device CDC/ACM: Fix backward conditional compilation in the + CDC/ACM driver with regard to remote wakeup and self-powered + capabilities. From the PX4 team via Lorenz Meier, + + * Networking / Network Drivers + + - ARP IP harvesting: Correct backward condition in netmask task. + From Max Holtzberg. + - Network connection monitor: Fixes a race condition where a loss of + connection may not be detected when the connection is lost before it + has been accepted (from Max Holtzberg). + - TCP/IP Backlog: Fix a critical bug in the TCP/IP backlog + initialization: Only the first backlog buffer was getting added to + the free list. From Max Holtzberg. + - ENC28J60: Fixes and improvements back-ported from the ENCX24J600 + to the ENC28J60 by Max Holtzberg. + + * STM32 Drivers: + + - STM32 I2C fixes for the STM32 F3 family from John Wharington. + - STM32 I2C Correct an error that crept into the STM32 F1 I2C + driver with some recent changes. From Librae + - STM32 F4: Added some missing CONFIG_SERIAL_TERMIOS support; Fixed + some STM32 F4 Timer 8 pin configurations. From CCTSAO. + - STM32 SDIO: If CONFIG_SDIO_BLOCKSETUP defined, OS would crash. Now + Generate an error if CONFIG_SDIO_BLOCKSETUP is defined; that + option is not yet supported by the STM32 SDIO driver. From CCTSAO + - STM32 I2C Timers: Some CCER bit settings changed. Submitted by + CCCTSAO. + - STM32 CAN: Fix access to CAN filter registers. From the PX4 team + via Lorenz Meier. + - STM32 Kconfig: Fix STM32 UART7/8 Kconfig names and UART DMA. From + the PX4 team via Lorenz Meier. + + * LPC17xx Drivers + + - Fix #endif with missing #if in USB host header file. Reported + by Andrew Bradford, + + * SAM3/4 Boards: + + - Corrected DMA-related problems: Bad register definitions, parameters + reversed in a function call. + - Correct a race condition in the HSMCI driver when an interrupt + occurs before the wait for the interrupt begins. + - Peripheral clock setup: Correct a typo in a register name. + + * Atmel AT91 SAMA5D3 + + - Order of some operations changed in boot-up logic to defer + enabling of caching of memory regions until SDRAM is initialized. + - Correct handling of spurious interrupts. + + * Freescale KL25Z Drivers + + - KL25Z SPI: Correct typo in name of a function. From Alan Carvalho + de Assis. + + * Applications: + + - apps/examples/composite: Fix a typo that can cause a configuration + error. From CCTSAO. + - apps/examples/pwm: Clean-up some configuration confusion. + - apps/netutils/dhcpd/dhcpd.c: Fixed calculation of the next lease + address. From Paolo Messina. + - apps/examples/usbmsc: Don't try to control USB trace if we are + an NSH built-in task. In that case our attempts are inadequate + and only interfere with with other logic that is attempting to + to do the same thing (in NSH or in the USB monitor). + - apps/examples/usbmsc: IMPORTANT bug fix: Change how the msconn + works. Because of recent changes the msconn command was hanging. + This was because the USB MSC start-up logic creates a pthread; + Now waitpid() will wait until all members of the task group + exit. So NSH was hanging in waitpid when msconn started even + though msconn returned. The USB MSC logic really should not use + a pthread, but we are stuck with that for now. The work-around + is the msconn now daemonizes itself so that it so that the pthread + is created in a different task group. + - apps/nshlib: Fix NSH listing output for the case of a single file. + From the PX4 team; provided by Lorenz Meier. + +NuttX-6.31 +---------- + +The 98th release of NuttX, Version 6.31, was made on October 28, 2013, +and is available for download from the SourceForge website. Note +that release consists of two tarballs: nuttx-6.31.tar.gz and +apps-6.31.tar.gz. Both may be needed (see the top-level nuttx/README.txt +file for build information). + +Additional new features and extended functionality: + + * General: + + - Standardized stack checking logic so the interfaces can be used + by common stack monitoring logic. + + * Audio Subsystem and Audio Drivers: + + - Ken Pettit has finally released his long awaited audio subsystem. + This is a generic audio subsystem that is appropriate for the + deeply embedded MCU. Current testing has, however, been focused + on the VS1053 CODEC chip. + - Ken Pettit's VS1053 audio CODEC driver is now functional. + + * Networking / Network Drivers + + - Add the prefix ETH0 to all PHY configuration selections. This + will allow us to support to Ethernet MAC drivers with two different + PHYs (identified with ETH0 and ETH1). Enabled with CONFIG_NETDEV_MULTINIC. + - Add MII/RMII PHY definitions for the Micrel KSZ8051 PHY. + - Add GMII/GRMII PHY definitions for the Micrel KSZ9021/31 PHY. + - New network-optimized, higher-performance sendfile() implementation + from Max Holtzberg. + - Added a simple routing table. This table is currenly only used (1) + when we need to look-up an Ethernet device based on an IP address, + and (2) in the ARP logic when we need to request the MAC address of + the router, vs the MAC address of the peer. + - Make net_close() nonblocking and free unestablished connections if + no free connections available. From Max Holtzberg. + - Changed the meaning of the uip_*input functions. They now return + success when a packet is dropped; This is needed for the ENCX24J600 + driver that must make a decision to return the packet or not: It + should not retry dropped packets. From Max Holtzberg. + - David Sidrane has completed integration of the CC3000 networking. + This is much more than a network driver: It is a complete + replacement for the NuttX networking with off-chip networking support + in the CC3000. + - Numerous enhancements to the ENCX24J600 driver from Max Holtberg. + + * Other Common Drivers: + + - The SST25 serial FLASH MTD driver now includes support for the + SST25VF016B. From David Sidrane. + - Add a preflight method to the SDIO interface to support the STM32 + DMA usage model. From Mike Smith. + - Enhanced the MMC/SD SDIO driver to perform DMA preflight operations + and fail DMA read/write requests that fail preflighting. From Mike + Smith. + - Add an ioctl command that can be used to trigger ADC/DAC conversion + under application control. + + * File Systems: + + - Enhanced the FAT32 filesystem code to understand DMA preflight + failures, and to use the file sector buffer as a bounce buffer when + a user-supplied buffer is not suitable for DMA. From Mike Smith. + + * Atmel AT91 SAMA5D3x + + - Add support so that subsets of the total DRAM (and other external + memory) can be added to the heap, leaving other memory reserved for + other purposes (like the LCDC framebuffers). + + * Atmel AT91 SAMA5D3x Drivers: + + - Use more descriptive task names when starting the EHCI and OHCI + monitor tasks. + - Added a 10/100Base-T Ethernet (EMAC) driver. + - Added a 1000Base-T Ethernet (GMAC) driver. + - Added a Real Time Clock (RTC) driver and integrated with the NuttX + system time logic. + - Added support for /dev/random using the SAMA5D3x True Random Number + Generator (TRNG). + - Added a Watchdog Timer (WDT) driver. + - Added a Timer/Counter (TC) library with interface that make be used + by other drivers that need timer support. + - Added an ADC driver that can collect multiple samples using the + sequencer, can be trigger by a timer/counter, and supports DMA data + transfers. + - Added a touchscreen driver based on the special features of the + SAMA5D3 ADC peripheral. + - Added an LCD controller (LCDC) frame buffer driver. + - Added a CAN driver. However, testing has been delayed because of + cabling issues. + - Basic header file support is available for the Image Sensor + Interface (ISI) camera interface. Work on the camera driver is + underway and is expected in the next release. + + * Atmel AT91 SAMA5D3x-EK Development Boards + + - Add OS test support for the FPU test. + - Enable the task name feature board configuration sto provide + prettier ps command output. + - Added NX and NxWM configurations to verify the LCD and touchscreen. + There are still some outstanding issues with the NxWM configuration + as of this release. + - The TRNG and /dev/random are now enabled by default in the demo + configuration. + + * Atmel AT91 SAM3/4 Boards: + + - Add configuration to select revision 3 of the Arduino Due which has + some small but important differences. Suggested by gdi@embedders.org. + + * STMicro STM32: + + - Add support for the STM32F207ZE chip. From Martin Lederhilger. + + * STMicro STM32 Boards: + + - Add configuration for the Spark Core. The initial check-in is + basically the Maple Mini board and subsequent development by David + Sidrane is his special Spark emulation hardware. The configuration + should be very mature when actual Spark hardware is available. + - Support for the Olimex STM32 P207 board added by Martin Lederhilger. + - Configuration for the Mikroe STM32F4 board configuration updated for + audio support by Ken Pettit. + + * NXP LPC17xx Boards: + + - zkit-arm-1769: LED1 is now user controllable after booting. From + Rashid Fatah. + + * Kinetis KL Drivers: + + - PIT and TPM register definitions header files for the from Alan + Carvalho de Assis. + - Added low-level getc() function for operation with no file system. + The KL25Z can now support NSH in a very minimal system that does + not even have a file system. + + * Kinetis KL Boards + + - A new configuration called minnsh was added is an experiement to + see how small we can get the NuttX footprint and still support NSH. + From Alan Carvalho de Assis.. + + * TI Calypso Phones: + + - Basic board support for the Motorola C139 (Compal E86) phone. From + Craig Comstock. + + * Applications: + + - Moved several useful examples from apps/examples to apps/system. + This includes USB MSC, USB CDC/ACM, and USB Composite. + - New addroute and delroute commands added to NSH in order to manage + the network routing table. + - Numerous enhancements and updates to the CC3000 example from David + Sidrane. + - Add a new stack monitor daemon that can be used to constantly + monitor stack usage by all threads. + - Numerous changes to get NSH working with no file system. Basically + this suppresses I/O redirection and replaces file I/O with calls to + low-level console read/write functions. Suggested by Alan Carvalho + de Assis. + - apps/system/nxplayer: A new, command-line media player called + 'nxplayer' from Ken Pettit. + - apps/examples/random: Add a simple test that dumps values from + /dev/random. + - apps/examples/adc: Add support so that a ADC driven by software + triggering can be tested. + + * Build System: + + - The MKDEP tools now support a new argument that identifies the + object file path. + +Efforts In Progress. The following are features that are partially +implemented but present in this release. They are not likely to be +completed soon. + + * kconfig-fronted Configuration: + + - Conversion of old configurations to use the kconfig-frontends + tool is an ongoing effort that will continue for some time. + At this time, only 48% of the configurations have been converted + to use the kconfig-frontends tools. + +Bugfixes (see the ChangeLog for details). Some of these are very important: + + * Initialzation and Scheduling: + + - IDLE thread initialization logic should not call group_setupidlefiles() + if there are no file descriptors (and, hence, no file system). + - Fix some cornercase error handling logic: If sched_releasetcb() is + called as part of a failed pthread startup before the flags field in + the TCB has been initialized, then a crash occurs. Pointed out by + David Sidrane. + + * Networking / Network Drivers: + + - Look up of a device using subnet will fail if the packet is being + sent out of our subnet (via a router). The fallback here is just to + use the only device ("eth0") if the subnet lookup fails (this logic + was extended to handle multiple Ethernet devices by adding a simple + routing table). + - Fix some backward conditional logic in send() that enabled the + check if the ARP address is in the ARP table. From Max Holtzberg. + - Notify the socket layer from the network monitor if a connection is + lost before the monitoring callback has been registered. From Max + Holtzberg. + - send(): Reset the send timeout when the data is ACKed, not when the + data is sent. Remove conditions on checking for timeout. From Max + Holtzberg. + - Correct how the TCP/IP initial minimum MSS is calculated. Max + Holtzberg. + - TCP state machine: Move tcp connection into SYN_RCVD state after + aception instead of bypassing and moving directly into ESTABLISHED. + From Max Holtzberg. + - Numerous fixes to the ENCX24J600 driver from Max Holtberg. + + * USB Drivers: + + - Change naming of SELFPOWERED and REMOTEWAKEUP to avoid name + collisions. Prepend the name of the driver (for example + CDCACM_SELFPOWERED). + - CDC/ACM class driver: Change the interval for the interrupt + endpoint from 0xff (invalid) to 10. This is not a critical + change but will avoid a complaint from the Linux driver when + it overrides the 0xff value. + + * ARM Cortex-A5: + + - Fix an error in data cache clean and invalidate functions: Fix of + addresses to cache line boundaries. + + * Atmel AT91 SAMA5D3x Drivers: + + - Correct some inconsistencies in the way that USB configuration + settings are used. This caused compilation errors in SAMA5 OHCI + when USB debug was ON but USB host tracing was off. + - When 480MHz UPLL is used to drive OHCI, it should have a divider + of 10. However, that does not work. A divider of 5 does. Why?. + - OHCI HCD: Fix a place where DMA-related data needed to be flushed + to data cache; Fix another where a virtual address was being used + in a register where a physical address was required. + - HSMCI Driver: TX DMA disabled. It is just not reliable. No idea + why. RX DMA is still used. + - STM32F103C pinmapping corrections from David Sidrane. + + * Atmel SAMA5D3x-EK Board + + - Increase the number of pre-allocated watchdog timers. The default + number of 4 was easily being exhausted in the more complex + configurations. + + * STMicro STM32: + + - STM32 F4 DMA definitions: Typo fixes for UART7 and UART8 DMA + configs. From Mike Smith. + - DMA priority configuration corrections from Mike Smith. + - Changes to the stm32_dmacapable API. In order to correctly + verify that a buffer can be transferred, the transfer count and + the CCR value are required. Implemented stm32_dmacapable for + stm32f1xx devices. Enhanced stm32_dmacapable for stm32f2xx and + stm32f4xx devices to check for additional conditions that will cause + DMA to fail or lose data. + - STM32 F1 DMA fix from David Sidrane: The DMA_CNDTRx register + cannot be modified if the DMA channel is disabled. + + * STMicro STM32 Drivers: + + - Fix compilation errors from bad bit definitions in ADC and PWM + register. From Martin Lederhilger. + - DMA-related fixes to the SPI driver from Ken Pettit. + + * NXP LPC17xx Drivers: + + - Remove undefined spi_select() prototype. This was causing compile + time warnings. + + * NXP LPC17xx Boards: + + - zkit-arm-1768: MMC/SD is on SPI, not SSP0. From Rashid Fatah. + + * C Library + + - scanf() fixes from kfrolov: 1) sscanf() function hangs in the + following example: sscanf("2", "%u,%u,%u,%u", ...), 2) sscanf() + returns incorrect number of parsed numbers if some arguments + can't be parsed: sscanf("=2", "%u,%u,%u,%u",...)==1 instead of + 0, and 3) using of char* instead of const char* in vsscanf + function leads to warnings from GCC. + + * Build System + + - Dependency generation generation was broken for directories that + keep objects in a sub-directory. The MKDEP tools now support a new + argument that identifies the object file path. + - tools/define.sh: 'cut' no longer works as it once did. Script + adapted to observed behavior. + + * Applications: + + - Remove a warning from the NSH library when DHCP is not enabled. + - Default NSH IP address should be 0x0a000001 (10.0.0.1), not + 0xa0000001 (160.0.0.1). Ditto for the gateway. + - Add some missing options to the OS test Kconfig file + - Fix some bad conditional compilation in the USB monitor. + - Fix default I2C frequency used by the I2C tool: 400KHz instead + of 4MHz. Suggested by Max Kriegleder. + - Increase stack size for the system/info command. Ken Petit + reports that this simple command can exceed its 768 stack size + under certain conditions. The size is marginal and has been + increased to 1024 by default but is also now configurable. + - apps/Makefile: Needs to include external/Make.defs if we want + allow external applications to participate in the NuttX + configuration. Suggested by gdi@embedders.org. + - apps/netutils/telnetd: Missing argument to debug statement + can cause crashes in certain error conditions. From David + Sidrane. + - apps/examples/can: Correct an error in a debug statement. From + Martin Lederhilger. + +NuttX-6.32 +---------- + +The 99th release of NuttX, Version 6.32, was made on December 7, 2013, +and is available for download from the SourceForge website. Note +that release consists of two tarballs: nuttx-6.32.tar.gz and +apps-6.32.tar.gz. Both may be needed (see the top-level nuttx/README.txt +file for build information). + +Additional new features and extended functionality: + + * General: + + - Extension and standardization of stack debug logic. Now includes + coloration of the IDLE and interrupt stacks as well as the heap. + Suggested by David Sidrane. + + * Audio Subsystem and Audio Drivers: + + - I2S interface definition. Integrates with audio sub-system. + - VS1053 worker thread stack size is now configurable and assigned a + name via pthread_setname_np(). From Ken Pettit. + + * Networking / Network Drivers + + - Updates and adaptations to support for TI CC3000 wireless module + from David Sidrane. These updates include multi-threading support + and interface and header file changes to integrate more seamlessly + with NuttX applications. + + * File Systems: + + - procfs: Add support for a tiny procfs file system. The initial + offering is little more that a proof of concept but may be developed + further in subsequent releases. + - NXFFS: An initial attempt was made to integrate NXFFS with the NAND + MTD driver. Changes were made to handle bad blocks. However, I + later realized that NXFFS cannot handle NAND because the way that + is re-writes blocks is incompatible with the NAND ECC handling. + These changes were backed-out so as not to introduce turmoil, but + can be re-enabled if needed via configuration option. + - NXFFS: Make the start up scan of the media a configuration option. + It just takes to long and is not really necessary! Those rare cases + where the scan was helpful can be fixed using MDIOC_BULKERASE IOCTL + command. + + * General Drivers: + + - I2S: A simple character driver was added to support I2S accesses. + This driver in its current state is intended only to support I2C + testing and would not be appropriate to used for any real driver + application. + + * MTD Drivers + + - Add a container for an MTD device that can be used to provide a + simple, lightweight interface to configuration data storage that + resides on some storage media that is wrapped as an MTD device. + From Ken Pettit. + - New interface definition for lower half NAND drivers. + - MTD Nand: Add MTD NAND driver that will support ONFI devices, + non-ONFI devices (via table lookup), bad block checking, software + ECC (Hamming), and will interact with the lower-half, hardware- + specific, NAND driver. Based on BSD-compatible Atmel sample code. + - MTD geometry structure is now packed so that it can support larger + erase block sizes needed by NAND without increasing the size of + the geometry structure. + - SST25: Add another SST25 SerialFlash driver, sst25xx.c. This one + differs from sst25.c in that it supports larger SST25 parts: In + the larger parts support page write instead of byte/word writes + like the smaller parts. From Ken Pettit. + + * USB Drivers + + - STM32 F1 USB Device: Add support for decoded USB trace strings. + From David Sidrane. + + * ARM + + - Add more ARM9 cache management functions to flush and invalidate + D-Cache for DMA support. + + * Atmel AT91 SAMA5D3x Drivers: + + - Many new drivers including CAN, PWM, SSC/I2S + - PCK: Add support for programmable clock outputs. + - NAND: Driver with hardware ECC and DMA support + + * Atmel AT91 SAMA5D3x Boards: + + - SAMA5D3x-EK: Add support for the apps/examples/i2schar test. + - SAMA5D3x-EK: Provides board-specific memory controller initialize + for NAND flash. + - SAMA5D3x-EK: Add support for "auto-mounting" NAND MTD block driver + or NXFFS file system. + + * Atmel AT91 SAM3/4 Boards: + + - Basic support for the Atmel SAM4E family. From Mitko. + + * STMicro STM32: + + - Added support for the STM32F429. From Ken Pettit. + - Added support for GPIOK and GPIOJ. From Ken Pettit. + + * STMicro STM32 Drivers + + - STM32 F4 OTG FS/HS Device: OTG FS device and host drivers extended + so that they can support either the OTG FS peripheral or the OTG HS + peripheral (in FS mode). This was done as a quick way to get USB + support on the STM32F429 which has only OTG HS. From Ken Pettit. + - Added header files and driver framework for the STM32F429 LTDC + framebuffer driver. From Ken Pettit. + + * STMicro STM32 Boards: + + - Support for the Spark board was completely by Davide Sidrane. The + Spark configuration includes integrated CC3000 wireless support, FAT + file system on the SerialFlash and a composite device that can be + used both to export the FAT file system and to provide a serial + interface. + - The Mikroe-stm32f4 now uses /dev/config for configuration data + storage. From Ken Pettit. + - Added support for the STM32F429I-Discovery board from Ken Pettit. + - Added board support for the ViewTool STM32F103/F107 board with the + STM32F107VCT6 installed. + + * NXP LPC31xx Drivers: + + - USB ECHI HCD: Add a driver for the low-/full-/high-speed variant + of the EHCI host controller. + + * NXP LPC31xx Boards: + + - Board-specific USB host support for the Emedded Artists EA3131 board. + (Missing PCA9532 controls). + - Add support for the Olimex LPC-H3131 board. Including USB host + support (which does not depend on the PCA8532 interface). + + * Kinetis KL Drivers: + + - PWM driver for the Freescale Kinetis KL family from Alan Carvalho + de Assis. + + * Kinetis KL Boards + + - Freedom-KL25Z: Add PWM support from Alan Carvalho de Assis. + + * TI Stellaris LM3S + + - Don't initialize .data in start-up logic if not running from FLASH. + + * Applications: + + - apps/platform: A new home for platform-specific application code. + - Define a common interface that can be used to manage platform- + specific configuration data. From Ken Pettit. + - apps/examples/configdata: A unit test for the MTD configuration + data driver from Ken Pettit. + - Aapps/platform/mikroe-stm32f4: dd platform-specific storage of + configuration data for the Mikroe-stm32f4. From Ken Pettit. + - apps/examples/cc3000: Fine tuning of memory usage from David Sidrane. + - apps/system/nxplayer: Play thread stack size is now configurable. + All NxPlayer threads now have names assigned via pthread_setname_np(). + From Ken Pettit. + - apps/examples/i2schar: The I2S test based on the I2S character + driver. + - apps/examples/hidkbd/hidkbd_main.c: Now calls a function named + arch_usbhost_initialize() that must be provided by the platform- + specific code. + - NSH: + + - hexdump: Add skip= and count= options to the hexdump command. From Ken Pettit. + - Allow USB trace without a USB console. From David Sidrane. + - Mount command updates from Ken Pettit. + - Add an option to the mkfatfs command to specify FAT12, FAT16, or FAT32. + + * Tools + + - tools/mkctags.sh: A script for creating ctags from Ken Pettit. + +Efforts In Progress. The following are features that are partially +implemented but present in this release. They are not likely to be +completed soon. + + * kconfig-fronted Configuration: + + - Conversion of old configurations to use the kconfig-frontends + tool is an ongoing effort that will continue for some time. + At this time, only 50% of the configurations have been converted + to use the kconfig-frontends tools. + +Bugfixes (see the ChangeLog for details). Some of these are very important: + + * File Systems + + - FAT: In one error return case, the error return value was not being + set, making the failure look like success. From David Sidrane. + - mount: SMART FS must be included in the conditional compilation for + the set of file systems that require block drivers. From Daniel + Palmer. + - SmartFS: Fixed a minor bug with SMART partition number reporting + that would only be seen if both partition support and multi-root + directory support are enabled at the same time. From Ken Pettit. + - Deadlock: The inode semaphore must be re-entrant. Here is the re- + entrant path that I found: (1) USB host connects to FLASH drive and + creates /dev/sda, (2) /dev/sda is mounted, (3) FLASH drive is + removed but /dev/sda is not destroyed because there is still a + reference on the device because of the mount, (4) umount() is + called, taking the inode semaphore, now the driver tries to destroy + the block driver by calling unregister_blockdriver(). But (5) + unregister_blockdriver() also takes the inode semaphore causing a + deadlock if the inode semaphore is not re-entrant. + - FAT: Fix a typo in the FAT16 formatting logic. Was this ever able to + format a FAT16 volume? + + * MTD Drivers + + - MTD Partitions: Fix erase block vs page block confusion. From Ken + Pettit + - SST25 Serial Flash: Improved write performance by fixing a bug that + prevented operation in the faster write mode. From David Sidrane. + + * USB Drivers: + + - USB MSC Device: pthread_join() does not work if called from a + different task group than the pthread. This is correct behavior, + but still a problem. The correct solution would be configure the + USB MSC thread to a task, however, this workaround from David + Sidrane plugs the hole for now. + - USB CDC/ACM, USB MSC, and Composite Device Classes: Un-initialization + logic caused re-use of a stale pointer. Changed to a two pass + un-initialization for the case of the composite driver: Memory + resources are not freed until the second un-initialization pass. + From David Sidrane. + + * STMicro STM32 Drivers: + + - STM32 F1 USB Device: Fix some errors that cause crashes when the USB + was disconnected. From David Sidrane. + - STM32 F1 USB Device: Correct EP0 state handling logic when buffers + larger than the EP0 packet size are sent. From David Sidrane. + - STM32 F1 USB Device: The long outstanding bug involving the handling + of OUT SETUP commands has been fixed in the STM32 F1 USB device + driver by David Sidrane. + - Kconfig: Add missing setup of CAN TSEG1 and TSEG2 values. From + Martin Lederhilger. + + * Tools + + - tools/mkconfig.c: SMART FS must be included in the conditional + compilation for the set of writable file systems. Noted by Daniel + Palmer. + + * Applications: + + - apps/platform/Makefile: Was not dealing with the bin sub-directory + correctly. + - apps/system/composite/composite_main.c: The wrong handle was getting + nullified. From David Sidrane. + +NuttX-6.33 +---------- + +The 100th release of NuttX, Version 6.33, was made on January 30, 2014, +and is available for download from the SourceForge website. Note +that release consists of two tarballs: nuttx-6.33.tar.gz and +apps-6.33.tar.gz. Both may be needed (see the top-level nuttx/README.txt +file for build information). + +Additional new features and extended functionality: + + * Core OS Interfaces + + - nanosleep() added. sleep() and usleep() are no longer core OS + interfaces. These have been moved into the library and re-implemented + as simple wrappers around nanosleep(). + + * File Systems + + - procfs restructured by Ken Pettit. Added files for MTD status. + - procfs extended to show uptime and task group status. + - procfs now shows stack information. + + * Networking + + - Add support for the SO_LINGER socket option. Extended from logic + provided by Jason Jiang. Enabled with CONFIG_NET_SOLINGER. + - TCP write buffering support added. From Jason Jiang. + - Changes from Max Holtzberg to improve how network status is + reported. New controls to manage carrier detect. + + * Graphics + + - Massive reshuffling of files with little or no logic changes. This + reshuffling was necessary to build graphics applications with the + kernel builds where the graphics application lie in user space and + the core graphic server likes in kernel space. Moved much logic out + of nuttx/graphics to a new user library, libnx. + + * Cortex-A5/A8/A9 + + - Existing Cortex-A5 support updated to include Cortex-A8/9. + - Add the syscall.h header file needed for the Cortex-A architecture. + - Start-up logic now supports execution from FLASH with .data and + .bss in SDRAM. This was not possible prior to this because .bss + and .data were initialized before SDRAM was configured. + + * Allwinner A10: + + - Basic support for the Allwinner A10 (Cortex-A8) is in place. + + * Allwinner A10 boards + + - Support for the pcDuino v1 board has been added. This support + is not yet very mature and still lacks many drivers. It is a + good starting point, however, if anyone wants to develop A10 + support. + + * Atmel SAMA5D3X + + - Start-up logic now supports execution from FLASH with .data and + .bss in SDRAM. This was not possible prior to this because .bss + and .data were initialized before SDRAM was configured. + + * Atmel SAMA5D3X Boards + + - Partial logic in place to support the OV2640 camera. Still needs + quite a bit of additional logic to be useful. + + * ARMv7-M + + - Add support for high priority, nested interrupts. This change + effects not only core ARMv-7M logic, but all ARMv7-M MCU logic: + LM3S, LM4F, LPC17xx, LPC43xx, SAM3, SAM4, and STM32. See + http://www.nuttx.org/doku.php?id=wiki:nxinternal:highperfints + + * STMicro STM32 + + - Add clocking support for STM32F107 USB OTG FS (which does not yet + work) + - Single-wire UART support for the F1 series from Thomas Grubler. + + * STMicro STM32 Boards + + - The Viewtool board can now be configured to support either the + STM32F103VCT6 or the STM32F107VCT6. + - The Viewtool STM32F107VCT6 now supports networking with the + DP83848C module installed. + - Add support for Viewtool SSD1289-based LCD on the Viewtool + STM32F103VCT6 board (untested) + - Add support for the XPT2046 touchscreen controller on the Viewtool + LCD module connected to the Viewtool STM32F103 board. + - Added kernel mode build support for the STM3240G-EVAL board. Added + a new kernel mode NxWM build configuration + - C++ static constructor logic from the nuttx/configs/stm3240g-eval/ + directory to the apps/platform/stm3240g-eval/up_cxxinitialize.c + where is belongs so that it is available in user-space in the kernel + mode build. + - Add native Windows build support for the Olimex STM32 P107. From + Max Holtzberg + - Support for the STM32VL-Discovery board. Contributed by Alan + Carvalho de Assis + - Added a configuration for testing simple configurations on the + PX4FMU v2. + + * ZiLOG ZNEO Boards + + - Add an NSH configuration for the Z16F2800100ZCOG ZNEO board. + - Added support for the Toyaga 16Z ZNEO board. The 16Z board is + based on the ZiLOG ZNEOZ16F2811AL20EG part. See + https://github.com/toyaga/16z for further information + - Developed a patch to work around a compiler error that is revealed + when building the NSH configuration. + + * Architecture-Independent Drivers + + - OV2640 Camera Driver. + - Support for the Sharp Memory LCD from Librae. + + * Library + + - Pattern matching logic extended to handle set of characters and + ranges of character values. From Ken Pettit. + - sleep() and usleep() moved intot the C library. These are not + longer core OS interfaces; they are simple wrappers for the + nanosleep(). + - Add an implementation of gets_s(). + - Extend fopen() to include support for C11 exclusive open ("x") + open mode. + - Add an implementation of stpcpy() + - strtol(), strtoll, strtoul(), strtoull(), and strtod() from + libc/string to libc/stdlib where they belong. + + * Header Files + + - Add rsize_t to include/sys/types.h + - Add the C11 thread.h header file + + * Configuration/Build System + + - Top level Makefile now supports qconfig and/or gconfig targets that + may be used for configuration. These may be used if you build + kconfig-frontends with support for kconfig-qconf and/or + kconfig-gconf. + - Add CONFIG_DEBUG_NOOPT. Now you can independently enable/disable + debug symbols and optimization + - File system related header files moved to include/nuttx/fs + - Video related header files moved to include/nuttx/video + - Changes for native Windows build: fix creation of a .version file + if one does not exist. Make sure that the APPDIR environment + variable is set before configuring. From Max Holtzberg. + - Board configuration sub-directory can now be specified. The default + need not be used. This is only useful when CONFIG_ARCH_BOARD_CUSTOM + is selected and there is no meaningful default sub-directory. + - Many functions renamed to better conform with the naming standard: + up_buttoninit() renamed to board_button_initialize(), up_buttons() + renamed to board_buttons(), up_irqbutton() renamed to + board_button_irq(), up_ledinit() renamed to board_led_initialize(), + up_ledon() renamed to board_led_on(), and up_ledoff() renamed to + board_led_off(). All prototypes removed from board.h header files. + Now ONLY prototypes in include/nuttx/arch.h. + + * Applications + + - NSH: Refactor. Separate NSH command handling and command execution + from NSH line parsing. + - NSH: Will now support multiple commands on a command line, each + separated with a semi-colon. + - NSH: Add support of commands enclosed in back quotes as command + arguments. + - NSH: Can now handle arguments that are concatenations of constant + strings, command return data, application return data, and + environment variables. + - NSH: Add true and false commands. + - NSH: Add support for while-do-done and until-do-done loops. These + only work when executing a script file because they depend on the + ability to seek in the file to implement the looping behaviors. + Can be conditionally compiled out to reduce footprint. + - NSH: Loosen up if-then-else-fi syntax to allow a command to be on + the same line as the then or else tokens like: + "if true; then echo true; else echo false; fi". More like bash. + - NSH: Add a break command that can be executed with a loop to + terminate the loop immediately. + + - system/inifile: A simple .INI file parser. + - system/vi: Add support for a tiny, VI work-alike editor. This is + a minimal full screen editor that works with a terminal emulator + that using VT100 commands. + +Efforts In Progress. The following are features that are partially +implemented but present in this release. They are not likely to be +completed soon. + + * kconfig-fronted Configuration: + + - Conversion of old configurations to use the kconfig-frontends + tool is an ongoing effort that will continue for some time. + At this time, only 53% of the configurations have been converted + to use the kconfig-frontends tools. + +Bugfixes (see the ChangeLog for details). Some of these are very important: + + * Core OS + + - Added missing sem_timedwait() system call. + + * Networking + + - Prevent tcp_connect callback from being double freed. From Max + Holtzberg + - uiplib: Support new definitions and state passing for network + device status. From Maz Holtzberg. + + * File Systems + + - FAT: (1) A correction to FAT cluster allocation, and (2) Fix to some + root directory logic that was conditionally done only for FAT 32. + Apparently this needs to done for all FAT types.

To disable the + interrupt, you need to set a bit in the ICER register. Existing + logic was trying to disable interrupts by clearing the bit in the + ISER register. That will not work; writing a '0' to the ISER + register has no effect. That means that up_disable_irq() was + doing nothing! It turns out that that is not really important + because up_disable_irq() is not really used for that purpose. But + some spurions STM32 ADC interrupts have been reported to me and this + turned out to be the cause in that case.

From Ken Pettit. + +NuttX-7.1 +--------- + +The 101st release of NuttX, Version 7.1, was made on March 15, 2014, +and is available for download from the SourceForge website. Note +that release consists of two tarballs: nuttx-7.1.tar.gz and +apps-7.1.tar.gz. Both may be needed (see the top-level nuttx/README.txt +file for build information). + + The previous NuttX version was 6.33. The NuttX minor version number is + incremented on each release, but the major version number is incremented + only when an incompatibility with previous versions is included in the + release. In this case, the legacy, manual configuration is no longer + supported by the NuttX build system beginning with NuttX 7.1. Only the + newer configurations generated by the kconfig-frontends tools will generate + viable NuttX configurations. + + All board configurations in the NuttX source tree have been converted to + use the newer configuration, but if you have some older style configurations + for you board, you will need to convert those configurations to use the + kconfig-frontends tools before taking any new code from the repository. See + http://www.nuttx.org/doku.php?id=wiki:howtos:convertconfig for some + guidelines. + +Additional new features and extended functionality: + + * Core OS: + + - System time logic now includes logic to measure and calculate the + CPU load percentage (from David Alessio). This CPU load logic + extended to keep counts on each thread. The per-thread CPU is + now reported in the procfs under /loadavg An asynchronous, + "external" clock may be used to drive the CPU load calculations + for more accurate measurements when needed. + + * File Systems: + + - As mentioned above, the per-thread CPU load information is now + reported in the procfs under /loadavg. + - Many file system interfaces have been extended to operate on the + top-level NuttX pseudo filesystem. These include rmdir, mkdir, + rename, and unlink. This capability can be disabled with + CONFIG_DISABLE_PSEUDOFS_OPERATIONS in order to keep the footprint + small. + + * Networking: + + - Numerous updates and improvements to the CC3000 driver from David + Sidrane. + + * Common Drivers: + + - Defined a mouse interface that is very similar to a touchscreen + interface, but allows reporting of all mouse buttons. Also, unlike + touchscreen drivers, mouse drivers need to report positional data + with no button is pressed so that the mouse position can drive a + cursor. + - Added support for a USB HID boot mouse device. Cursor support is + not integrated and must be provided by the application based upon + the reported mouse data. + - Support added for the MIO283QT9A LCD from Toby Duckworth. + + * Atmel SAMA4E: + + - Added complete architecture support for the Atmel AT91 SAM4E + Cortex-M4F parts. + + * Atmel SAM4E Board Support: + + - Add board support for the SAM4E-EK board. + + * Atmel SAM4E Drivers: + + - Added logic to manage the Cortex-M Cache Control block. + - Developed and integrated an Ethernet MAC driver for the SAM4E. + - Backported the SAMA5 SPI driver to the SAM3/4 architecture. The + SAMA5 version supports both multiple SPI peripherals as needed by the + SAM3A and SAM3X and also supports DMAC (but not PDC) needed by the + SAM4E. + + * Atmel SAM D20: + + - Added basic architecture support for the Atmel AT91 SAM D20 + Cortex-M0+ parts. + + * Atmel SAM D20 Board Support: + + - Added basic support for SAM D2 Xplained Pro board. Currently, the + NuttShell (NSH) works reliably over a serial port. An SPI driver + has also been developed. Work with the SAM D20 has been temporarily + stopped, however, in order to focus on the SAM4E-EK. + + * TI Tiva TMC4C123G: + + - Added architecture support for the TI Tiva TM4C123G parts. This was + merged into the existing support for the LM3S and LM4F families. + All directory, file, and function references changed from lm to tiva. + + * TI Tiva TMC4C123G Board Support: + + - Added basic board support for the TM4C123G-Launchpad. As of this + release the TM4C123G-Launchpad board support is untested and likely + incomplete. + + * STMicro STM32 Boards: + + - The Mikroe STM32F4 can now support the newer MIO283QT9A LCD. From + Toby Duckworth. + - Miscellaneous changes to better support FPU on STM32F429 Discovery + from David Alessio. + + * NXP LPC2378 Drivers: + + - Incorporated I2C and SPI drivers for the LPC23xx from Lizhuoyi. + + * QEMU i486 Drivers: + + - New QEMU keyboard and VGA drivers from Lizhuoyi. + + * Documentation: + + - Added a coding standards document. See + http://www.nuttx.org/doku.php?id=documentation:codingstandard + + * Configuration/Build System: + + - A configuration option, CONFIG_DEFAULT_SMALL, was added to select + default values for configuration variables based upon whether you + want a smaller footprint or more features. This is not very useful + if you are modifying existing configurations because then the + default values do not apply. + - CONFIG_DEFAULT_SMALL has been defined on all tiny MCU configurations + so that they do not grow so rapidly when new, optional features are + added. + - The legacy, manual configuration is no longer supported by the + NuttX build system. Only the newer configurations generated by + the kconfig-frontends tools will generate viable NuttX + configurations. All board configurations in the NuttX source tree + have been converted to use the newer configuration, but if you have + some older style configurations for you board, you will need to + convert those configurations to use the kconfig-frontends tools. See + http://www.nuttx.org/doku.php?id=wiki:howtos:convertconfig for some + guidelines. + + * Applications: + + - NSH can now use an EMACS-like command line editor. This CLE, is + really more like the traditional readline than is the default, tiny + the NuttX readline . + - The touchscreen example can now be configured to work with either a + touchscreen or a mouse device. + - Several NSH commands can now be used to operate on objects in the + top-level pseudo-filesystem: rmdir, mkdir, mv, and rm. This + capability can be disabled with CONFIG_DISABLE_PSEUDOFS_OPERATIONS + in order to keep the footprint small. + - If both the CPU load feature and the procfs features are enabled, + then the NSH 'ps' command will show the CPU load used by each + thread. + +Bugfixes (see the ChangeLog for details). Some of these are very important: + + * Core OS: + + - task_terminate() always returned an error because the return value + was not being set correctly (from Gosha). + - nanosleep() Fix a missing call to re-enable interrupts (from Jason + Jiang). + + * File Systems: + + - Fixed an error in the FAT logic that can cause file corruption. The + error conditions are rare and only seen with very large files (from + Andrew Tridgell). This replaces a previous, partial fix for the same + problem. + - Fixed memory leaks in the NXFFS open() and stat() implementations + (from Lzyy). + - The interfaces include opendir(), readdir(), et al, were modified so + that errors will not be reported if you attempt to list a empty + pseudo-directory. + + * Networking: + + - Fix one place where the connection reference count was not being + decremented in the socket close() logic. This is really a cosmetic + change BUT when CONFIG_DEBUG_NET is enabled, it will cause assertions. + - Backed out a small part of the NuttX 6.33 write buffering changed. + David G says that this causes problems in connecting to a server. + - In DHCPD, there was a place where the logic was calling ntohl() + inappropriately; the address was already in the correct order. How + could DHCPD have worked with this bug? + + * TI Tiva/Stellaris Drivers: + + - Fixed cut'n'paste error that prevented UARTS2-7 from being used with + the LM4F120 Launchpad. + - Fixed several errors there were unmasked with UARTs > UART2 are + enabled (grom Gosha). + + * Allwinner A10 Drivers: + + - Fixed cut'n'paste error that prevented UARTS2-7 from being used with + the pcDuino. + + * NXP LPC17xx Drivers: + + - Fix an compilation error that crept into the LPC17xx USB host driver. + + * STMicro STM32 Drivers: + + - Fix cloned typo in the serial driver: FLOWCONTROL vs FLOWCONROL. + - Disable SPI before changing DPI CR1 register (from David Sidrane). + - stm32 TIM: Set the timer CCMR when selecting timer channel. From + David Sidrane. + - Fix typo in a Makefile: stm32_pwm.c not stm32_psm.c. Noted by Max + Kriegleder. + + * Library: + + - More sscanf() bug fixes from David Sidrane. + + * Header files: + + - cstdbool: Ignore _Bool8 if CONFIG_C99_BOOL8=y + + * Configuration/Build System: + + - Several changes to restore the broken native Windows build + + * NuttShell (NSH): + + - Use strncpy vs strcpy in the Telnet console logic to avoid + overrunning the username and password buffers (from Bertold Van den + Bergh). + - Add a newline after printing the file in the 'cat' command. This + prevents the NSH prompt from be in the same line as the final line + of the file in the case where there is no newline at the end of the + file. + +NuttX-7.2 +--------- + +The 102nd release of NuttX, Version 7.2, was made on April 29, 2014, +and is available for download from the SourceForge website. Note +that release consists of two tarballs: nuttx-7.2.tar.gz and +apps-7.2.tar.gz. Both may be needed (see the top-level nuttx/README.txt +file for build information). + +Additional new features and extended functionality: + + * Core OS: + + - Add support for CLOCK_REALTIME. From Macs N. + + * Network Utilities: + + - Add a very primitive NTP client. + - DNS resolver: Long needed major clean up for coding style and + unification of naming conventions (resolv vs dns). + + * Common Drivers: + + - Add a new MTD driver that can be used to contain another driver and + force its apparent sector size to be 512 bytes. + - If DCD can support queuing of stall requests, then the USB MSC stall + work around delays are not necessary. + - Redesign threading module used with the USB MSC driver. It was using + pthreads before and these were changed to a kernel thread. The reason + for this has to do with task grouping: A pthread is a memory of the + group of the task that started it. A kernel thread is independent of + the task that started in (other than knowing it as the parent). This + allows me to remove so kludge logic to "deparent" the pthread on + startup. + - Update the MIO183QT-9A LCD driver to support reading from the LCD. + From Toby Duckworth. + - Timer "upper half" driver and l"lower half" interface definition from + Bob Doiron. + + * Atmel SAM4E/4S Board Support: + + - All SAM4E configurations updated to run with 120MHz CPU speed and + with the CMCC enabled. + - Support for the SAM4S Xplained Pro board from Bob Doiron. + - Add watchdog driver. From Bob Doiron. + + * Atmel SAM4E/4S Drivers: + + - Add a USB full speed device driver (UDP) for the SAM4E. + - Add support in HSMCI and SPI drivers to invalidate cached memory if + the CMCC is enabled. + - Add logic to handle SPI word widths > 8 + - Port RTC driver from SAMA5 to SAM3/4. From Bob Doiron. + - HSMCI: Extensions from Bob Doiron needed to support PDC-based HSMCI + DMA transfers. Verified on the SAM4S Xplained Pro. + + * Atmel SAMA5: + + - Add support for the SAMA5D36 chip. + - Add functions to calculate PLLACK, PCK, and MCK frequencies given + the main clock frequency. + - Implemented RAM functions. When booting directly into NOR flash, + reconfiguring the PLL while executing out of NOR FLASH causes + crashes. This was fixed by David Sidrane by implementing RAM + functions. The killer code is copied and executed from ISRAM and + the crash is avoided. + + * Atmel SAMA5 Drivers: + + - Add support for the SAMA5D3 DBGU. + + * Atmel SAMA5 Board Support: + + - Add a board support configuration for the Atmel SAMA5D3 Xplained + board running out of SDRAM. When booting from SDRAM, start-up logic + needd to query the PMC registers to determine the MCK, PCK, etc. + - For all SAMA5 boards, added support for 528MHz clocking. + + * TI Tiva/Stellaris: + + - Modify the logic to disables the interrupts and sets the default + interrupt priority so that it uses the ICTR to get the number of + interrupt lines/registers. This is instead of using some fixed + number of initializations based a priori knowledge of the number + of interrupt lines in the MCU. + + * STMicro STM32 + + - Add support for the STM401RE. From Frank Bennett. + + * STMicro STM32 Boards: + + - STM32F4Discovery: Add support to register keyboard and mouse + classes if so configured. From Leo. + - Add support for the Nucleo-F401RE board. From Frank Bennett. + + * STMicro STM32 Drivers: + + - Add STM32 Ethernet IGMP hashing support. From Manuel Sthn. + - OTG FS Host: USB host tracing added by Leo. + + * Freescale Kinetis + + - Modify the logic to disables the interrupts and sets the default + interrupt priority so that it uses the ICTR to get the number of + interrupt lines/registers. This is instead of using some fixed + number of initializations based a priori knowledge of the number + of interrupt lines in the MCU. + + * NXP LPC17xx + + - Modify the logic to disables the interrupts and sets the default + interrupt priority so that it uses the ICTR to get the number of + interrupt lines/registers. This is instead of using some fixed + number of initializations based a priori knowledge of the number + of interrupt lines in the MCU. + + * ZiLOG ZNEO Drivers + + - Added ZNEO ESPI driver. + + * Library: + + - Finish incomplete support for ferror(). From Macs N. + + * Documentation: + + - UsbTrace.html: Add some discussion of the USB monitor. + + * Configuration/Build System: + + - compiler.h: Add macro UNUSED() that can be used to eliminate + warnings about variables that are set to values that are not + used. + + * Debugging Support: + + - Add a configuration option to enable dumping of the USB trace buffer + on assertion. + + * Applications: + + - IGMP Example: Fill out Kconfig file; update makefile so that the + IGMP example can be used as an NSH built-in application. From Manuel + Sthn. + - lcdrw Example: Fill out empty Kconfig file. + - touchscreen Example: Add a configuration option to indicate if + architecture-specific initialized is required, yes or no. + - System usbmsc: Back out the USBMSC daemon... it is no longer needed + with the recent fix to the USBMSC class driver. + - NSH: malloc/free IOBUFFER for 'cat' and 'hexdump' commands instead of + using the stack. From Bob Doiron. + - cpuhog, serialblaster, and serialrx Examples: Stress test examples + added by Bob Doiron. + +Bugfixes (see the ChangeLog for details). Some of these are very important: + + * Core OS: + + - errno_get_errno_ptr() and getpid(): Add some checks. If these + functions are called very early in initialization before the tasking + structures are initialized, they would not behave properly. + + * Networking: + + - IGMP-related bug fixes from Manuel Sthn. + - In netdev_findbyaddr(), skip network devices that are in the "down" + state. It does not make sense to consider an address match with a + "down" device. From Brennan Ashton. + + * Network Utilities: + + - DHCPD: The correct value of the PAD option. Should be zero, not + one. From Brennan Ashton. + - Corrections to the NTP client from Manuel Stuehn. + + * Common Drivers: + + - usbhost.h: Fix some USB HID-related conditional compilation. From Leo. + - USB HID mouse driver: Don't include NAKs from the device in the error + count. From Leo. + + * TI Tiva/Stellaris: + + - Add corrected control logic for TM4C125GXL based on logic from Daniel + Carvalho with modifications. The LM4F120 also works well with this + change. + + * STMicro STM32 Drivers: + + - STM32 F2 SPI: Correct a mapping for SPI MOSI pin. From dlsitzer. + - OTG FS Host: Fixes related to low-speed devices and interrupt + endpoints from Leo. Necessary in order to use a USB HID mouse + device. + - STM32 SDIO: The dmaflight method must be conditioned on + CONFIG_SDIO_PREFLIGHT. Noted by Pelle Windestam. + - Sourceforge Ticket #26. up_prioritize_irq should not be called + if CONFIG_ARCH_IRQPRIO is not defined. + + * Atmel SAM3/4: + + - Fix some backward conditional compilation in the start-up logic. + - Fix initialization of the default interrupt priorities. This is + a critical bug fix! + - SAM4S: Fix error in macros that disable peripheral clocking. From + Bob Doiron. + + * Atmel SAMA5: + + - Fix double mapping of SDRAM when executing out of SDRAM. In this + case, the SDRAM was already mapping in arm_head.S. + - In clock configuration, the BMS bit handling was fixed to match + what the HW really does. From David Sidrane. + - TLB Bufferable bit did not do what I thought it was going to do. + I though I was selecting a write-through cache, but the result was + that all caching was disabled and NOR FLASH accesses were very slow. + - Move the un-definitions of __ramfuncs__ from the clock configuration + .c file to the .h file. Otherwise, the attribute will be applied + differently for the prototype and the function definition. + Sourceforge patch 38 from Luciano Neri. + + * Atmel SAMA5 Drivers: + + - Fix a case in the UDPHS driver where received status was not being + cleared, causing OUT SETUP commands to fail. + - TWI data sending fails to increment the number of bytes transferred + on first byte sent. from David Sidrane. + - If running from SDRAM, then BOARD_MCK_FREQUENCY is not a constant + and cannot be used in conditional compilation. All drivers fixed + EXCEPT for the PWM and Timer/Counter drivers which will need some + more extensive redesign. + + * Atmel SAMA5 Boards: + + - SAMA5D3x-EK: The red LED is controlled by PE24 which is also the + camera/ISI interface reset line. So if the a camera is installed, + then we must avoid controlling the red LED or we inadvertently + also reset the camera module. Noted by David Sidrane. + - Header files reference type xcpt_t in certain configurations and + so must include nuttx/irq.h. This is Sourceforge bug 25 submitted + by Luciano Neri. + + * NXP LPC17xx Drivers + + - arm/src/lpc17xx/Kconfig and lpc17_ethernet.c: The default interrupt + priority should be default, not the highest priority (2014-4-19). + + * ZiLOG ZNEO + + - Fix calculation of timer reload and prescaler. The timer frequency + was way too fast. + + * Library: + + - strncpy(): Change ordering of test and copy. Logic would have + failed if n=0; one byte was always copying before testing + for the end of the copy. + - Fix a counting error in the return value from sscanf(). Noted by + kfrolov. Also, sscanf() should return EOF if no values were + converted. + - Fix a logic error in ftell(). It was simply using the file offset + and did not take into account data buffered in memory. From Macs N. + - sccanf(): Use stroul() vs strol() with %u format otherwise, range + of values is restricted because of sign bit. From kfrolov. + + * Configuration/Build System: + + - Fix a build error that occurs when only USB device tracing is enabled. + + * NuttShell (NSH): + + - Fix NuttShell version number display in the NSH welcome message. + version.h was not being included. + + * Other Applications: + + - sysinfo: CONFIG_VERSION_BUILD is a string an needs to be + printed with %s, not %d. Noted by Librae. + - nxplayer: Compilation failure in one configuration reported by + Manuel Stuhn. + - System sdcard: Remove an STM32 dependency. From Bob Doiron. + - telnetd Example: Naming is confused. In someplaces 'telnetd', + and in others 'shell.' All changes to telnetd. Noted by Pelle + Windestam. + +NuttX-7.3 +--------- + +The 103rd release of NuttX, Version 7.3, was made on June 25, 2014, +and is available for download from the SourceForge website. Note +that release consists of two tarballs: nuttx-7.3.tar.gz and +apps-7.3.tar.gz. Both may be needed (see the top-level nuttx/README.txt +file for build information). + +Additional new features and extended functionality: + + * Core OS: + + - Dynamic loader: Framework to support Pascal P-Code as a binary + format that can be exec'ed from a file system. + - Dynamic Loader: Extend the binfmt interface to handle error + conditions where format-specific clean-up is needed in the event + of error conditions. This is needed by the P-Code binfmt. + + * Networking + + - IOB: Add a generic I/O buffer chain logic. This logic uses small, + pre-allocated buffers that can be chained together to support + transfers of any size, using fewer resources and also without + committing in advance to a TCP window size. There is now only + one I/O type used in the networking and it is these I/O buffer + chains. + - TCP Write Buffering: TCP write buffering logic converted to use + I/O buffer chains. + - TCP Read-Ahead Buffering: TCP read-ahead buffering logic converted + to use I/O buffer chains. + - Includes logic to support throttling of read-ahead buffering if + the read-ahead buffering is competing with write buffering for + I/O buffers. + - Raw Sockets: Add support for the AF_PACKET socket family. From + Daniel Lazlo Sitzer. + + * Common Drivers: + + - W25 Serial FLASH driver extended by Mark Whitehorn to support the + 8Mbit W25Q80BV part. + - Add support for Fujitsu MB85RS1MT RAMTRON part. From Charles Ash. + - Enhancements to the generic timer interface to support capture mode + from Bob Doiron. + - Add an rxflowcontrol method to the serial interface to better + support RX flow control. This involves common changes in addition to minor updates to all MCU-specific serial drivers (only fully implemented for the STM32). From Jussi Kivilinna. + + * Atmel SAM4C + + - Add support for the SAM4CM family. From Max Neklyudov. + + * Atmel SAM4E/4S Drivers: + + - RTT driver from Bob Doiron. Also added high resolution RTC + emulation using the RTT for the sub-second counter. + + * Atmel SAM4E/4S Board Support: + + - The SAM4S Xplained Pro now uses the extended timer/counter + features. From Bob Doiron. + - Added a touchscreen and LCD driver for the SAM4E-EK board (the LCD, + however, not yet fully functional). + + * Atmel SAMA5: + + - Optimized, high performance, assembly language memcpy(). This is + the same optimized memcpy() function that Mike Smith brought in + for the ARMv7-M with minor tweaks by David Sidrane to work with + the ARMv7-A. + - Basic support added for the SAMA5D4 family. + + * Atmel SAMA5 Drivers: + + - SAMA5D4: New drivers unique to the SAMA5D4: XDMAC, SAIC, and + others. + + * Atmel SAMA5 Board Support: + + - SAMA5D4-MB: Initial board support for the SAMA5D4-MB/EK boards. + + * STMicro STM32 + + - Add support for the STM32152 and STM32162 Medium+ density parts + (plus miscellaneous other improvements to the original STM32151 + logic). From Jussi Kivilinna and Sami Pelkonen. + + * STMicro STM32 Boards: + + - Support for the Olimex STM32 H405 board contributed by Martin + Lederhilger. + + * STMicro STM32 Drivers: + + - Implement the rxflowcontrol method to the serial interface to better + support RX flow control. From Jussi Kivilinna. + + * NXP LPC17xx Drivers: + + - Added support for the RTC, ADC, DAC, Timers, PWM and MCPWM + drivers. From Max (himax). + + * NXP LPC17xx Boards: + + - Support for the RTC, ADC, DAC, Timers, PWM and MCPWM integrated + in the LPCXpresso LPC1768 board support. From Max (himax). + + * Library: + + - Add support for seek-able streams. + + * Configuration/Build System: + + - Restructured network directories, header files, and naming to + better modularize the networking and to better integrate the + networking with the rest of NuttX. + + * Applications: + + - prun: An NSH built-in application that can be used to run + Pascal P-Code programs either programatically or from the NSH + command line. + - netpkt: A "raw" socket test from Lazlo Sitzer. + - hex2bin: A library and built-in task to convert from + Intel HEX to binary format. It can write the binary data to a file or it can store the binary data to memory (to support, for example, a loader). + +Bugfixes. Only the most critical bugfixes are listed here (see the ChangeLog for the complete list of bugfixes and for additional, more detailed bugfix information): + + * Core OS: + + - Dynamic Loader: Fix an error in a symbol table search function. + Noted by Pelle Windestam. + - Dynamic Loader: Fix a critical error in exec(); argv was not + being passed. + - mq_notify: Test for a valid signal number was inverted; this + function could not have been working correctly before??? From + eero.nurkkala. + - Fix typo in conditional compilation: CONFIG_CLOCK_MONOTONIC vs. + CLOCK_MONOTONIC. From Manuel Sthn. + + * Graphics + + - Fix typos in several RGB conversion macros. + + * Networking: + + - Modify TCP timout handling to provent situations where connections + may not be freed. From Max Holtzberg. + - Improved TCP fallback allocation logic from Max Holtzberg. Also, + fallback mechanism is disabled when SO_LINGER is to prevent + deadlocks. + - Write Buffering: Add checks from buffer allocation failures. From + Max/Himax. + + * Network Utilities: + + - webserver: httpd_fs_open() should return OK on success and ERROR on + failure, not 1 and 0. + + * Common Drivers: + + - Make sure that all references to up_prioritize_irq() are + conditioned on CONFIG_ARCH_IRQPRIO. Problem noted by Mike Smith. + - CC3000: Correct SPI mode for CC3000 is CPOL=0 CHPA=1. From Jussi + Kivilinna. + - CC3000: Fix a race condition in thread start-up logic. From Jussi + Kivilinna. + - CC3000: Additional fixes including a compilation failure if POLL is + enabled. From Jussi Kivilinna. + + * USB Drivers: + + - CDC/ACM and PL2303 device: Reset RX head to avoid resending last + serial data when USB cable disconnected/re-connected. From + Lizhuoyi. + + * TI Tiva/Stellaris Boards: + + - The Nucleo-F401RE has no on-board crystals and, hence, needs to run + with the PLL input from the on-chip HSI clock. + + * STMicro STM32 Drivers: + + - Serial: Handle configuration for the case of 8-bit data with + parity. From Freddie Chopin. + + * Atmel SAM3/4 Boards: + + - There was a cloned error in all SAM3/4 board configurations (and + for a few other architectures as well). Button interrupts not + being disabled after being detached. As a result, unexpected + interrupts could be received after the button interrupt was + detached. + + * Atmel SAMA5: + + - Fix some critical typos in the SAMA5D3 DMA definitions. + + * STMicro STM32 Drivers + + - I2C: Add an alternative I2C implementation for the STM32 F103 that + works around errata in that specific part. From Patrizio Simona. + - RTCC: Add retry logic to RTC initialization. It sometimes takes + longer for the RTC to initialize, at least as noted on an F2 part. + From Daniel Lazlo Sitzer. + + * NXP LPC17xx Drivers + + - GPDMA: Fix an error when DMA is started: The read-modify-write + fails when the DMA is started. This is because the value read is + not the same as the value set (on write it is the number of + transfers to do; on read it is the number of transfers completed). + From Lizhuoyi. + + * Library: + + - snprintf(): If the size passed to snprintf() is zero, then + snprintf() must write nothing, but instead return the size of the + buffer needed to hold the entire string. From Sami Pelkonen. + + * Configuration/Build System: + + - The alternate console device CONFIG_NSH_CONDEV must not be defined + unconditionally. This causes errors when using Telnet sessions. + This was solved by adding CONFIG_NSH_ALTCONDEV: CONFIG_NSH_ALTCONDEV enables or disables the feature then, if + enabled, CONFIG_NSH_CONDEV provides the alternative console + device name. + - Many files: Convert all old-style GCC variadic macros to the C99 + form. Recent GCC changes tightens up that behavior and can cause + some problems (at least for the IAR compiler for some reason). + Noted by Bob Grimes. + - tools/configure.sh: In-place SED edit messes up permissions on + windows. From Hannes Delago. + + * Build Tools: + + - tools/mkfsdata.pl: Apparently, the trailing the 0x00 in http + server files is seen as a bug in javascript and images. From + Max/Himax. + + * Other Applications: + + - I2C Tool: Fix to show the updated register address on each + fetch (vs. showing the same starting address each time). From + Ryan VanSickle. + - CLE was not returning the terminating newline character. But + reported by Max kriegleder. + +NuttX-7.4 +--------- + +The 104th release of NuttX, Version 7.4, was made on August 15, 2014, +and is available for download from the SourceForge website. Note +that release consists of two tarballs: nuttx-7.4.tar.gz and +apps-7.4.tar.gz. Both may be needed (see the top-level nuttx/README.txt +file for build information). + +Additional new features and extended functionality: + + * Core OS: + + - Beginnings of a crypto/ subsystem from Max Neklyudov + - Tickless operation: NuttX now supports a mode with no periodic + timer interrupts. Rather, timed events are handle via an interval + timer. This (1) lowers the rate of interrupt processing to timer + events, (2) gives much high timing resolution, and (3) allows lower + power modes of operation where the CPU is not constantly being + interrupted by the timer. + - Restructured the OS files under sched/ to better support the already + modular nature of the RTOS. + + * Networking + + - Substantial directory and header file reorganization and renaming to + make the NuttX networking implementation more modular. + - Add network device ioctl to access PHY registers. From Daniel Lazlo + Sitzer + + * Binary Loader: + + - Various changes associated with symbol tables from Pelle Windestam. + + * Graphics: + + - colorcmp(): New utility to compare two colors. + - The initial background color is now configurable. Includes logic to + eliminates multiple background updates to get the right color. + - Minor configuration changes to handle mouse X/Y and touchscreen + X/Y differently. + + * File System/Block Drivers: + + - SmartFS: Increase some variables from uint16_t to uint32_t to handle + larger device sizes. From Ken Pettit. + - Add configurable AES encryption support to the block-to-character + (BCH) driver. This allows any block device to be accessed as an + encrypted character device. From Max Nekludov + - Add an MTD layer that will add read-ahead or write buffering to any + MTD driver (incomplete). + - Automounter: Add support for an auto-mounter that will automatically + mount and unmount a file system a media is inserted and removed + + * Audio/Audio Drivers + + - WM8904 audio CODEC driver. + - PCM .WAV file decoder. Fast forward implemented with sub-sampling + (currently no rewind support). + - Add a NULL audio device that can be used to simply unit-level testing + of audio decoders. + - Audio subsystem now supports interfaces for fast-forward and rewind + needed by CMediaPlayer; add hooks for equalizer settings needed by + the WM8904 CODEC. + + * Other Common Drivers: + + - MTD: Extend erase block size to 18-bits in order (decrease block + size to 14-bits) to handle parts with large erase blocks. From Kosma + Moczek + - maxTouch: Add support for the Atmel maXTouch touchscreen controller. + + * Host Simulation: + + - Provides the timers needed to support the Tickless mode of operation. + + * Atmel SAM4C: + + - Add SAM4CM IPC register header file. From Max Neklyudov + - Various fixes PMC and clock configuration for the SAM4CM port from + Max Neklyudov + + * Atmel SAM4E/4S Drivers: + + - SAM4 AES driver. Contributed by Max Neklyudov + + * Atmel SAMA5: + + - Add logic to redirect all SAMA5D4 interrupts to the AIC + - Add a configuration option to reserve DRAM for a framebuffer when + executing out of DRAM. This optional was available before when + executing out of NOR, but needs to work a little differently in + this case. + - Add SAMA5 slow (32.768KHz) clock support. + - Add support for the ARM L2CC-PL310 L2 cache. The system runs with + L2CC cache enabled but there is some issues still with the LCD DMA; + I suspect that the memory timing configuration for L2CC needs to + be tuned. + - Provides the timers needed to support the Tickless mode of operation. + + * Atmel SAMA5 Drivers: + + - XDMAC-based HSCMI driver for the SAMA5D4 + - Adapt the SAMA5D3 LCDC driver to work with the SAMA5D4 which has + no hardware cursor. + - PIO: Add a new interface sam_pio_forceclk() that can be used to + force PIO clocking on. I am afraid I was too conservative with + PIO clocking in the initial design; this is the price. + - TWI: Now supports the up_i2creset() method. + - TWI: Use sam_pio_forceclk() so that we can read the current state + of an open-drain output in the TWI reset logic. + - SSC: SCC Frame Synch Delay and Start Delay are now configurable. + - PCK: Add the slow clock and the main clocks as options for the + PCK configuration. + - Timer/Counter: Can now handle non-constant BOARD_MCK_FREQUENCY. Also + now supports methods to attach client interrupt handlers + - One shot and free-running timers. These are wrappers around the low + level timer/counter logic to provide one-shot and free-running + timers. These were developed to support the Tickless operation, but + can be used for any purpose. + + * Atmel SAMA5 Board Support: + + - Add a boot loader that runs from ISRAM and loads an Intel HEX file + into DRAM. + - Add a configuration that will load a bootloader into AT25 Serial + FLASH + - SAMA5D4-EK NSH configuration supports many more features: RTC, HSCMI + card detection, maXTouch touchscreen, TM7000 LCD, the command line + media player (currently using the NULL audio device), automounter, + and others. + - SAMA5D4-EK: Add an NxWM configuration using the TM7000 LCD with + the maXTouch multi-touch touchscreen. + - SAMA5D4-EK NxWM: Uses new, larger icons in configuration instead of + scaling. + - SAMA5D4-EK NxWM: The NxPlayer and audio system are now enabled in + the default configuration (but currently using the NULL audio + device). The automounter is used to automatically mount media + on an SD card. + - SAMA5D3x-EK: Add a configuration to support the command line + NxPlayer and to verify the WM8904 CODEC driver. + + * STMicro STM32: + + - Add support for the STM32F103RC and RD. From Kosma Moczek + - Add a procfs entry to show the state of the CCM heap usage. + From Pelle Winderstam + + * STMicro STM32 Drivers: + + - Unconfigure GPIO pins when closing a serial port to prevent back + effects from back-powering on the TX pin. From Kosma Moczek + + * NXP LPC17xx Drivers: + + - ADC: Added burstmode ADC conversion mode, with CONFIG_ADC_BURSTMODE + option in Kconfig. From Max + - Ethernet: Added option to use the kernel worker thread to do most of + the workload with CONFIG_NET_WORKER_THREAD option in Kconfig. From Max + - Ethernet: Critical bugfix: From time to time (after some hours) the + Ethernet receiver would lose one receive interrupt and the IP stack + never recover because there is no receive watchdog as the transmit + watchdog. From Max + + * NXP LPC17xx Boards: + + - mbed: Port ADC, DAC, and PWM logic from the configs/zkit-arm-1769. + From Max + - mbed: Eliminated a problem with PHY DP83848C : it doesn't need a + specific initialization on mbed. From Max + + * Library: + + - Adds support for localtime. From Max Neklyudov + + * Configuration/Build System: + + - Make variable definitions 'static const' when possible to save RAM + usage. From Kosma Moczek + + * Applications: + + - sysem/mdio: New PHY tool from Daniel Lazlo Sizter. + - NSH: Networking logic modified to handler the case of SLIP + transport. From Max Neklyudov. + - NSH: Add a configuration to use a USB keyboard for the stdin + device. + - NSH: Software assigned MAC address is now configurable. From Lazlo. + - NSH: Also add an option to let platform-specific logic select the + MAC address. + - NSH: There is now a configuration option that will bring up the + network on an separate thread. Since the network bring-up is + asynchronous, there are no serial console start-up delays due + to the network negotiation time. + - NxPlayer: Changes to integrate with Ken's NxWM::CMediaPlayer. + - NxPlayer: Add interfaces for fast-forward and rewind needed by + CMediaPlayer; add interface for equalizer settings needed by the + WM8904. + - NxPlayer: Supports new way of identifying the end of the audio + stream (see the Audio section above). + - Sudoku: Add a sudoku game. + +Bugfixes. Only the most critical bugfixes are listed here (see the ChangeLog for the complete list of bugfixes and for additional, more detailed bugfix information): + + * Graphics: + + - NxConsole: Fix scrolling for the case of the framebuffer device. In + this case, the logic for clearing the vacated region at the bottom + was missing so garbage would scroll up from the last, uncleared + line. + + * Networking: + + - Important fix to the read-ahead buffer queue management: Consumed + bytes were being trimmed from the head of the queue, but the queue + head itself was not being updated. From Rony XLN. + - Fix an error in SLIP escaping. From Max Neklyudov + + * Network Utilities: + + - Fix an include file ordering problem when CONFIG_NET_STATISTICS=y. + - Move statistics from uip.h to new netstats.h to remove a circular + inclusion problem + - Various fixes for networking and tiny webserver from Max + - webclient: Fix to offset calculation from Rony Xln. Prevents 0x0a + at the beginning of lines. + - webserver: Fix some configuration usage issues. From Max. + - webserver: Missing logic to close sockets on loop termination. + + * File System / Block Drivers: + + - SmartFS: Fix for a bug that would show up if CONFIG_MTD_BYTE_WRITE + was not selected and the SMART sector size was larger than the MTD + device's block size (like it would be if using SMARTFS on larger + flash devices). From Ken Pettit. + + * Audio: + + - Change how the end of the audio stream is detected by the leaf audio + component. This used to be done by looking for the first partial + buffer. That does not work with the in-place sub-sampling performed + by the PCM decoder: That always reduces the size of the buffer so + that all buffers only partially filled by the time they get to the + leaf. Now, a flag is set in the audio buffer flags set to indicate + the final buffer in the stream. + + * Common Drivers: + + - RAMLOG putc() method needs to set the errno and return EOF on a + failure. + - Add missing configuration option to select the MAX11802 touchscreen + controller. From Petteri Aimonen + + * Atmel SAMA5D3/4: + + - Fix logic in conversion of physical and virtual DRAM addresses when + running out of DRAM. This is an important bug fix for the SAMA5D3 + and 4 when running out of DRAM . + - Critical SAMA5D3 and 4 bug fix: PIO clocking must be enabled for + all input pins or else the value that is read never changes. + + * Atmel SAMA5D3/4 Drivers: + + - OHCI: Fix an error in a DEBUGASSERT statement. Caused an + assertion to fire inappropriately when a low- or full-speed device + was removed and CONFIG_DEBUG=y + - OHCI: Pointers to allocated port values were not being + nullified after being deallocated. This caused some assertions + to fire when debug was enabled + - SSC: Needs to account for data offset in audio buffer + + * ARMv7-M: + + - Correct the initial value of the BASEPRI register. This was + apparently never being initialized! From Max + + * STMicro STM32 Drivers: + + - I2C: Fix missing configuration of GPIO pins in I2C driver. Fix + from Alex D. + - STM32 OTGFS device: Various changes to try to reduce that amount of + time in interrupts handles and with interrupts disabled. From + Petteri Aimonen + + * Atmel SAM3/4 Drivers: + + - Ethernet: Wrong bits being cleared before OR-ing in new settings. + - Ethernet: Fix an error in the function that determines the number + of free TX descriptors. This is an important bugfix on busy + networks. + - I2C: Test for read or write operation was reversed. How could + this have worked before? + + * Atmel SAM3/4 Boards: + + - SAM4S Xplained-Pro: Correct description of LEDs and usage. From + Kosma Moczek + + * Atmel SAMA5: + + - PIO: Fix definitions that could disable PIO interrupt support if only + PIOE interrupts were enabled + - PIO: Macro SAM_PION_VBASE is not define-able for the SAMA5D4 and must + be replaced with a table lookup. + - PIO: Fix a typo in Schmitt trigger configuration; Configure pin as a + vanilla input first so that final pin configuration is more read-able + (i.e., easier to debug) + - PIO: Logic for Schmitt trigger selection backward + - SAMA5D4: Correct system timer frequency. Input clock is MCK/2, not MCK. + + * Atmel SAMA5 Drivers: + + - Ethernet: Wrong bits being cleared before OR-ing in new settings. + - Ethernet: Fix an error in the function that determines the number + of free TX descriptors. This is an important bugfix on busy + networks. + - HSMCI: The 8-byte SCR transfer was failing silently with the DMA + transfer, leaving the SD card in single bit mode. Fixed by adding + a non-DMA read transfer mode. + - HSMCI: Fix a problem on card insertion/removal callback handling. + Interrupts were being disable so that the callbacks occurred with + interrupts disabled. This resulted in loss of some interrupts and + some not-so-good behaviors. The solution is to perform all + callbacks on the work thread unconditionally + + * Atmel SAMA5 Boards: + + - PIO: Fix some cloned errors in SAM GPIO interrupt setup + + * NXP LPC17xx Drivers: + + - Ethernet: Comment out an assertion that is reported to fire + inappropriately. From Max + + * Library: + + - stdint.h: Correct naming of [U]INT_LEASTn_{MAX|MIN} and + [U]INT_FASTn{MAX|MIN}. From Kosma Moczek + - unistd.h: POSIX definitions should be defined to a value. rom Kosma + Moczek + - Fixes associated with rint() and related interfaces in the math + library. + + * Configuration/Build System: + + - NAME_MAX not available on SunOS; use FILENAME_MAX or MAXNAMELEN. + Noted by Douglas Beattie + + * Applications: + + - NSH: if # appears on line, need to comment ignore additional + commands on the line + - NxPlayer: Check for file read errors and end-of-file with zero + bytes read. Other error handling corrected as well. + - NxPlayer: NxPlayer needs to set curbyte field to zero before + enqueuing a buffer. Otherwise, it looks like beginning of the + buffer has already been consumed. + +NuttX-7.5 +--------- + +The 105th release of NuttX, Version 7.5, was made on September 28, 2014, +and is available for download from the SourceForge website. Note +that release consists of two tarballs: nuttx-7.5.tar.gz and +apps-7.5.tar.gz. Both may be needed (see the top-level nuttx/README.txt +file for build information). + +Additional new features and extended functionality: + + * Core OS: + + - Watchdog Timer Allocation: (1) If we run out of pre-allocated + watchdog times, the logic will now allocate additional timers + from the heap. A reserve of pre-allocated watchdog timers is + maintained so that there will always be timers available for + interrupt handlers. (2) Added support for statically allocated + watchdog timer + - Address Environment Support: (2) New OS APIs integrated into all + platform-specific context switching logic (up_block_task(), + up_unblock_task(), _exit(), and others). + - Kernel Build Support: (1) The MPU based "kernel build" renamed to a + protected build (CONFIG_BUILD_PROTECTED); added support for the a + new MMU-based "kernel build" (CONFIG_BUILD_KERNEL), (2) The system + call library can now be built with CONFIG_NUTTX_KERNEL. New + selection: CONFIG_LIB_SYSCALL. + - System Startup: Add configuration options to start the system from + a program on a file system (versus an address in memory). + - Startup Parameter Passing. There used to be two ways to pass + parameters to new tasks, depending upon the configuration: Either + (1) argv[] as created as an array with each string strdup'ed. Or + (2) argv[] array and strings were created on the stack before the + new task was started. Now, there is only one way, way (1). Way + (2) might be slightly more compact, but this is not worth carry the + complexity of two different ways of doing the same thing. + - Board Initialization: Add capability to perform initial board + initialization on a separate worker thread. This is needed because + there are many cases where initialization logic cannot execute on + the start-up/IDLE thread. That is because blocking or waiting is + not permitted on the IDLE thread. + + * Memory Management: + + - Granule Allocator: (1) Add a new function to reserve un-allocatable + regions in the granule heap. (2) Add interfaces to support + un-initializing a granule allocator. + - Page Allocator: Add a simple physical page allocator based on the + existing NuttX granule allocator. I am not certain if the granule + allocator is sufficiently deterministic for long range use, but it + gets get a page allocator in place for testing very quickly. + - Remove CONFIG_MM_MULTIHEAP. Non-multiheap operation is no longer + supported. + - sbrk(): sbrk() is now supported in the kernel build to permit + dynamically sized, per-process heaps. + - Per-Process Heaps: Space at the beginning of the process data space + is now reserved for user heap management structures. In the kernel + build mode, these heap structures are shared between the kernel and + use code in order to allocate user-specific data. + - User Heap Management: When a privileged thread exits, we have to + use the kernel allocator to free memory; when an unprivileged thread + exits, we don't have to do anything... heap memory will be cleaned + up when the address environment is torn down. + - Inter-Process Shared Memory Support: (1) Add implementation and + documentation for shmget(), shmctl(), shmat(), and shmdt(). (2) + Add system system calls to support the user call gate to the shared + memory interfaces. (3) Add platform-specific interface definitions + needed to support the shared memory feature. + - Virtual Page Allocator: Add support for a per-process virtual page + allocator. This is a new member of the task_group_s structure. The + allocator must be initialized when a new user process is started and + uninitialize when the process group is finally destroyed. It is + used by shmat() and shmdt() to pick the virtual address onto which + to map the shared physical memory. + + * File Systems/Block Drivers/MTD: + + - SMART FS and SMART FS procfs updates from Ken Pettit. + - The MTD Read-ahead/Write buffer layer appears is now functional. + + * Binary Formats: + + - Add logic to initialize the per-process user heap when each user + process is started. + + * Graphics: + + - Change all occurrences of NxConsole to NxTerm. + + * Networking: + + - PHY Interrupts: (1) Standardize a PHY interrupt attachment + interface. (2) Add support for an ioctl that can be used to notify + an application when there is a change in the network status + signalled by a PHY interrupt. + - Improved Send Logic: In the past, the first packet send to a new + network peer would fail; there would be no entry in the ARP table + for the peer and so an ARP request could replace that first packet. + Now as an option if CONFIG_NET_ARP_SEND=y, all send logic will (1) + check if the peer MAC address is in the ARP table and, if not, (2) + send ARP requests periodically to get the mapping and (3) wait for + the ARP response. Then (4) when the ARP response is received then + the actual send logic will be initiated. Thus there may be a delay + with the first packet sent to a new peer, but the packet should not + be lost + + * Host Simulation: + + - Emulated SPI FLASH driver for the sim target from Ken Pettit. + + * Intel x86: + + - The default host is now x86_64 and the -m32 option will be + automatically selected for simulation builds. + + * Intel 8051 Family: + + - Removed all support for the 8051 family architecture from the NuttX + source tree. The obsoleted code along with the removal patch can + now be found at misc/Obsoleted/. This code was removed because (1) + although some functionality has been demonstrated, I am not aware of + any really successful ports of NuttX to any 8051, and (2) the 8051, + with its hardware stack, forces limitations and complications to the + other architectures and make growth and development of NuttX more + complex. + + * ZiLOG ZNeo Boards: + + - configs/16z: Support for this board has been removed from the NuttX + source tree (but still can be found in the misc/Obsoleted + directory). This port is not ready for usage but may return to the + NuttX tree at some point in the future. + + * Atmel SAM3/4 Boards: + + - SAM4E-EK: Add (1) a fully-functional ILI9341-based LCD driver and + (2) a fully-functional NxWM configuration. + + * ARMv7-A: + + - Address Environments: Add support for application address + environments using the Cortex-A MMU. Implement standardized + platform-specific interfaces of NuttX address environment + support. + - Cache Operations: Implement standardized, platform-specific cache + operations. These are called from the ELF loader in order to flush + D-cache and invalidate I-cache after an ELF module has been loaded + into memory. With this change, ELF modules work correctly on the + SAMA5/Cortex-A platform. + - Kernel Build: (1) Add implementations of system call gate. (2) Add + CRT0 start-up file that can be linked with separately built user + programs. (3) Add support for delivery of use-mode signals in the + kernel build. (4) Add logic to initialize the per-process user heap + when each user process is started. (5) ARMv7-A exception handling + needs to work a little differently if we support user mode + processes. This is because R13 and R14 are paged differently + between user and SVC mode. + - Shared Memory Support: (1) Add logic necessary to handle remapping + of shared memory on context switches. (2) Extend virtual/physical + address conversions to include addresses in shared memory. (3) Add + implementation of platform-specific shared memory support. + + * Atmel SAMA5D Drivers: + + - Implement all network ioctls, including the new ioctl to setup PHY + event notifications. + - In kernel build with address environment, need logic to map user + virtual addresses to physical addresses, and vice versa. + + * Atmel SAMA5D Boards: + + - SAMA5D3 Xplained, SAMA5D3-EK, and SAMA5D4-EK: Convert existing + board specific PHY interrupt interfaces to use newly defined + standard interface. + - SAMA5D4-EK: Add a configuration for testing the kernel build + configuration. There are configurations to boot either from an SD + card or from and in-memory ROMFS file system. + - SAMA5D4-EK: Add documentation/support for Rev E. board. + + * STMicro STM32 Drivers: + + - Ethernet: Modified to support the change to the network ioctl + signature changes. Also add support for new ioctl to setup PHY + event notifications. + + * STMicro STM32 Boards: + + - STM32F4Discovery with STM32F4DIS-BB: Add a network enabled NSH + configuration for the STM32F4Discovery board with the STM32F4DIS-BB + base board installed. Includes support for the microSD card slot on + the STM32F4DIS-BB base board. + + * TI Tiva Drivers: + + - Add support for the TI CC3200. From Jim Ewing. + + * TI Tiva Boards: + + - Add support for the TI CC3200 Launchpad. From Jim Ewing. + + * C Library: + + - Re-implemented poll() delay using sem_timedwait(). + + * Configuration/Build System: + + - Export Target: In the kernel or protected builds, (1) only the user + libraries should be exported, (2) do not copy internal header files + or build scripts if this is a kernel or protected build, and (3) + needs to bundle up the user C startup file (crt0), not the kernel + head object for the kernel and protected builds. + - Add logic that will permit us to build user libraries with different + CFLAGS than kernel code. This is needed because we need the + -fno-common option when building ELF code to prevent SHN_COMMON + relocations. + + * Applications: + + - NSH: Extend the NSH network initialization logic. There is now an + option that will create a network monitor thread that will monitor + the state of the link. When the link goes down, the code will + attempt to gracefully put the Ethernet driver in a down state; When + the link comes back, the code will attempt to bring the network back + up. + - ELF Example: The ELF test/example has been extended so the + individual ELF test programs can link against the SYSCALL library + (if it is available) or against the C library to eliminate or + minimize the need for symbol tables. + - Change all occurrences of NxConsole to NxTerm. + - MTDRWB Example: Add an example to test MTD R/W buffering. + - OS Test Example: Add a trivial test of sem_timedwait. + + * Application Configuration/Build System: + + - Import Target: (1) Add logic that will allow building applications + against a NuttX export package (vs. the nuttx/ source tree). (2) + Add .config file to export package. (3) Create apps/import. Create + apps/import/Make.defs that does things like define CFLAGS; ELF build + requires -fno-common in CFLAGS. Copy some base logic from + nuttx/tools/Config.mk to apps/import/Make.defs. (4) Add + apps/import/scripts/gnu-elf.ld GCC linker script for ELF import + builds. + - All Makefiles: (1) Add an install target to all makefiles. For + the import build, the top-level Makefile now does two passes: (1) + builds libapp.a, then (2) installs the programs into apps/bin. (2) + Add program installation for CONFIG_BUILD_KERNEL in all Makefiles + that build a main(). (3) For kernel build, the object file + containing main cannot go into library because of name collisions. + The object file must be handled as a special case in every Makefile. + - All Built-In Programs: With kernel build (CONFIG_BUILD_KERNEL), + entry point to all tasks is main(), not some xyz_main(). + - NSH: Several commands must be disabled in the kernel build because + they depend on interfaces that are not available outside of the + kernel: dd, df, losetup, mkfatfs, mkdr, and ps. + - apps/tools/: (1) Add mkimport.sh to expload an NuttX import package + and install in apps/import. (2) Add mkromfsimg.sh script to create + a BOOT ROMFS filesystem image. + - ELF and NxFLAT Examples: Do not build test cases that use + task_create() if there is an address environment. + + * Tools: + + - refresh.sh: Add a tool to make refreshing configurations easier + when you want to do a lot of them. + - mksyscall.c: Build syscalls that do not need header files. + - mkexport.sh: Add .config file to export package. + - See above for new apps/tools scripts. + +Efforts In Progress. The following are features that are partially +implemented but present in this release. They are not likely to be +completed soon. + + * Processes. Much of the work in this release is focused on the + realization of Unix-style user processes in NuttX. There is more to + be done, however. The full roadmap and status is available at: + http://www.nuttx.org/doku.php?id=wiki:nxinternal:memconfigs#the_roadmap_toward_processes + + * XMega: There are some fragments in place for an XMega port. That + port has not really started, however. + + * Galileo: Similarly, there are fragments in place for an Intel Galileo + port. The port not been started in earnest either. + +Bugfixes. Only the most critical bugfixes are listed here (see the ChangeLog for the complete list of bugfixes and for additional, more detailed bugfix information): + + * Core OS: + + - Kernel build fixes: (1) IDLE TCB setup needs to indicate that the + IDLE thread is a privileged, kernel thread. (2) Don't build + task_create() or task_spawn() interfaces if there is an address + environment. (3) posix_spawn() kernel proxy thread should be a + kernel thread, not a user task. + - Several pthread interfaces: Add const storage class to phthread + parameters. From Freddie Chopin. + - sched/clock: Remove vestiges of g_tickbias; need, instead, to apply + time bias to g_basetime in order to provide the correct system time. + - System Calls: (1) Several typos fixed; corrected integration of + exevc(), execvl(), posix_spawn, and posix_spawnp system calls. (2) + If we are configured to use a kernel stack while in SYSCALL handling, + then we need to switch back to the user stack to deliver a signal. + + * File Systems/Block Drivers/MTD: + + - procfs: Fix some procfs breakage introduced by reorganizing some + non-reorganizable data structures. From Ken Pettit. + - AT45: In at45db_bwrite , the buffer is not increased when writing + more than 1 page. Sourceforge bug #34. + + * Binary Formats: + + - ELF relocations. Some relocation types do not have a named symbol + associated with them. The design did not account for that case. + - ELF Loader: Critical bugfix.. BSS was not being cleared. + + * Memory Management: + + - Granule allocator initialization uses wrong allocator to setting + aside kernel memory. + - Add a flag to group structure: If the group is created by a kernel + thread, then all resources in the group must be privileged. + + * Cryptogrphic Support: + + - crypto/cryptodev.c: Path segments reversed in include file path. Noted by Brennan Ashton. + + * Common Drivers: + + - Common CAN upper-half: In can_txdone, waiters on the semaphore + should be informed regardless of the return value of can_xmit. First + it returns -EIO if there are no new packets, and second the + information of the waiters is about the last transferred packet. + From Daniel Lazlo Sitzer. + + * ARM: + + - System Calls: Fix a typo in system call when fetching parameter from + the stack: regs[REG_PC]+4 is the address, not regs[REG_PC+4]. + + * STMicro STM32 Drivers: + + - STM32 F401 UART: Correct support for USART6 on this chip. From + Freddie Chopin. + - STM32 FLASH fixes: use size_t instead of uint16_t, make interface + more generic. From Freddie Chopin. + - Fix for UART7 and UART8 on STM32 clock enable from Aton. + - CAN: At the end of the interrupt handler, the interrupts were being + disabled, if all packets have been transferred when the interrupt + handler was invoked. This is problematic, because the interrupt + handler calls can_txdone of the upper half which can enqueue new + packets to send. Removed the block altogether, because can_txdone + calls can_xmit which disables interrupts if there are no new packets + to send. From Daniel Lazlo Sitzer. + - Additional STM32 CAN correction suggested by Max Holtzberg. + + * STMicro ST32 Boards: + + - configs/mikroe-stm32f4: Fix a few compile bugs and minor corrections + to the mikroe-stm32f4 configuration source. From Ken Pettit. + + * ARM9/ARMv7-A: + + - System Calls: Fix ARM7/9 and Cortex-A SYSCALLs: For threads in SVC + mode, the SVC instructions clobbers R14. This must be taken account + in the inline assembly. + - Task Setup: All tasks, even user mode tasks, must start in + supervisor mode until they get past the start-up trampoline. + - ARMv7-A: Modify up_fullcontextrestore() for CONFIG_BUILD_KERNEL. + It changed CPSR while in kernel. That will crash if the new CPSR is + user mode while executing in kernel space. Fixed by adding a + SYS_context_restore system call. There is an alternative, simpler + modification to up_fullcontextrestore() that could have been done: + It might have been possible to use the SPSR instead of the CPRSR and + then do an exception return from up_fullcontextrestore(). That + would be more efficient, but I never tried it. + + * Atmel SAM3/4 Boards: + + - SAM3X/Arduino Due: Fix typo in sam3x_periphclks.h; add SCLK + definitions to board.h header file. From Fabien Comte. + - SAM3 RTT: Only SAM4 family has RTTDIS bit in the MR register. + SourceForge bug #33 from Fabien Comte. + + * C Library: + + - sscanf(): NuttX libc tried to guess how many characters to parse, + extracted them into a buffer, then ran strtol() on that buffer. + That guess was often wrong. A better approach would be to call + strtol() directly on the input data, using the endptr return value + to determine how many characters to skip after parsing. From Kosma + Moczek. + - Corrected atan2 implementations from Denis Arnst. + - Change to lib_dtoa() to fix precision error from trailing zeroes. + From Bob Doiron. + + * Applications: + + - Fix NSH PS command: If there are no arguments, it could print + garbage for argument list. + + * Configuration/Build System: + + - Null Example: Need to include config.h it order know if this is or + is not a kernel build. This problem still exists in several other + file that may need to define main(). + +NuttX-7.6 +--------- + +The 106th release of NuttX, Version 7.6, was made on November 26, 2014, +and is available for download from the SourceForge website. Note +that release consists of two tarballs: nuttx-7.6.tar.gz and +apps-7.6.tar.gz. Both may be needed (see the top-level nuttx/README.txt +file for build information). + +Additional new features and extended functionality: + + * Core OS: + + - Moved name semaphore and message queue support out of the OS and + into the VFS. These improves the architecture by unifying the + management of named resources, removes redundant resource management + logic, and makes named semaphores and message queues visible in the + file system. By default, these are visible at /var/lock and + /var/mqueue. + - Add SIGPOLL for use as part of the AIO implementation. + - Remove CONFIG_MAX_TASK_ARGS configuration. There is now no + predetermined limit on the number of arguments that may be passed + to a new task on start-up. + + * Work queues: + + - Add support for priority inheritance on the low priority worker + queue. That is, if a higher priority thread has scheduled work, the + priority of the low priority worker thread(s) will be boost to the + priority of the queuing thread. At work is performed at at least + thread priority of the scheduling thread. If there are multiple + worker threads, then all threads get reprioritized. Currently + only implemented for AIO. + - Add support for multiple low-priority work queue threads. This + allows individual worker threads to block indefinitely for I/O as + necessary without halting the entire work queue. + + * VFS/General Drivers: + + - Implement create() (as a macro). + - Add pread() and pwrite(). Also added pread() and pwrite() + system calls. + - AIO: Add aio_read(), aio_write(), aio_return(), aio_error(), + aio_suspend(), aio_canel(), lio_listio(), and aio_fsync(). This + logic minimizes the creation of new threads by using the new + features also added to the low priority work queue with this + release. It uses the new low priority worker thread interface + to adjust the priority of the worker thread according to the + priority of the AIO client thread + - Implement standard syslogmask() to control logging (also removing + the non-standard syslog_enable()). + + * File Systems/Block Drivers/MTD: + + - Extend MTD support to the M25P16. From Sbastien Lorquet. + + * Drivers: + + - BCH (Block-to-Character): Add support for seeking in BCH. From + Sbastien Lorquet. + + * Graphics Support/Graphics-Related Drivers: + + - Add support for a generic ILI9341 LCD driver. From Marco Krahl. + - Add ANSI/VT100 foreground and background color commands. + - Add driver for ST7565 LCD that works with NHD-C12864KGZ display. From Pierre-noel Bouteville. + + * Networking: + + - Verify that multiple networks can be supported. + - Add support for the case where there are multiple networks: One + being Ethernet and the other not (SLIP, PPP, ...). The primary + difference from the standpoint of the stack is that (1) ARP may or + may not be necessary, (2) the size of the link layer header will + vary, and (3) different MTUs and TCP receive windows may be used + with each link. Suggested by Brennan Ashton. + - Extensions to UDP and TCP connection structures for the case of + multiple networks. In this case, assigned port numbers only have to + be unique with respect to the IP address. So, for example, you + could have multiple port 80's, one on each network. + + * Host Simulation: + + - Removed the old, strange up_stdio.c and implemented a simulated UART + driver to provide the console input. The new logic starts a + separate, Linux domain pthread to read the console input in raw mode + and provides the incoming data to NuttX via standard NuttX domain + IPCs. + - Add support for 64-bit longjmp/setjmp in simulator platform. This + will permit operation of the simulation natively on a 64-bit + platform. + + * ARMv7-M: + + - Add ARMv7-M CMSIS ITM header file and library. From Pierre-noel + Bouteville. + - Add ARMv7-M CMSIS DWT and TPI header files. From Pierre-noel + Bouteville. + - Add ARMv7-M support to use ITM for SYSLOG debug output. Includes + logic from Pierre-noel Bouteville. + + * Atmel SAM3/4 Drivers: + + - Add support for SAM3/4 basic serial TERMIOS and flow control. + There are issues with IFLOW control: PDC or DMAC support is + required. + + * Atmel SAM3/4 Boards: + + - SAM4E-EK: Add support for PHY interrupt. + + * Atmel SAMA5D Boards: + + - SAMA5D3-Xplained: Add a configuration that provides a simple test + for the EMAC and GMAC on the SAMA5D3 working together. + - SAMA5D4-EK: Add a configuration that provides a simple test for the + EMAC0 and EMAC1 on the SAMA5D4 working together. + + * Freescale KL: + + - Add an I2C header file for the Freescale KL family. From Alan + Carvalho de Assis. + + * NXP LPC32xx: + + - Add support for tickless operation using the NXP LPC43xx. From + Brandon Warhurst. + + * SiLabs EFM32: + + - Add a basic port for the SiLabs EFM32 family. Includes many files + contributed by Pierre-noel Bouteville . + + * SiLabs EFM32 Boards: + + - Add board support for the EFM32 Gecko Starter Kit. + - Add board support for the Olimex EFM32G8809128 STK. NOTE: I am + unable to test this configuration due to tool-related issues. + - Add board support for the SiLbas EFM32GG Giant Gecko Starter kit. + + * STMicro STM32: + + - Add support for the STM32 F411RE from Serg Podtynnyi. + - Add support for the STM32F103RG. From Murilo Ponte. + + * STMicro STM32 Drivers: + + - STM32 F4: Add logic that implement true high speed support for the + STM32 OTGHS peripheral and concurrent support for both LS and HS + OTG. New OTGHS drivers provided for both device and host. From + Brennan Ashton. + + * STMicro STM32 Boards: + + - STM32 Nucleo-F411RE: Extend this board configuration to also support + the Nucleo-F411RE. From Serg Podtynnyi. + - Add support for the STM32F429i Discovery's LCD (SPI based). From + Marco Krahl. + - configs/stm32f100rc_generic: Removed this generic board configuration. + I have decided to stop support of generic board configurations. Generic + board configurations do not provide support for any specific hardware + but can be useful only if there are not other examples for the setup + for a particular architecture. Not the case here. + + * C Library: + + - Add a mostly bogus wchar.h header file. This file is mostly bogus + because none of the wide character operations are currently + supported in the Nuttx C library. The file does provide the wchar_t + types needed by some software, however. + - Add isatty() function. From Alan Carvalho de Assis. + - Add mktemp(), mkstemp(), tmpnam() and tempnam(). + + * Configuration/Build System: + + - Add a PRELINK macro to Config.mk. From Kriegleder. + - compiler.h: Defines inline functions as not instrumented - this is + relevant for anyone using instrumentation. From Lorenz Meier. + + * Applications: + + - apps/interpreter/bas: Added in the Michael Haardt's BAS 2.4 adapted + for use by NuttX by Alan Carvalho de Assis. Includes support for + VT100 terminals and color commands. + - Examples: Added bastest/ which holds a special version of Michael + Haardt's BAS 2.4 test files adapted for use by NuttX on a ROMFS file + system. + - Examples: Add a simple UDP relay bridge for testing configurations + with multiple networks. Includes a host-side test driver for + testing the bridge. + - Netutils: Add implementation of timeouts for the netutils webclient. + From Brennan Ashton + - NSH: Add support for a custom NSH ROMFS startup image header file + location. From Martin Lederhilger. + - OS test: Add a simple test of named semaphores. + - OS test: Add AIO test case in OS test. + +Efforts In Progress. The following are features that are partially +implemented but present in this release. They are not likely to be +completed soon. + + * Processes. Much of the work in this release is focused on the + realization of Unix-style user processes in NuttX. There is more to + be done, however. The full roadmap and status is available at: + http://www.nuttx.org/doku.php?id=wiki:nxinternal:memconfigs#the_roadmap_toward_processes + + * XMega: There are some fragments in place for an XMega port. That + port has not really started, however. + + * Galileo: Similarly, there are fragments in place for an Intel Galileo + port. The port not been started in earnest either. + +Bugfixes. Only the most critical bugfixes are listed here (see the +ChangeLog for the complete list of bugfixes and for additional, more +detailed bugfix information): + +I ran cppcheck against the entire code base and correct many latent bugs +including things as serious as memory leaks, two locations where interrupts +were be disabled but never re-enabled, and errors in the Tickless mode of +operation. My thanks to the developers of cppcheck! I am impressed! + + * Core OS: + + - vfork(): Now that arguments are kept on the stack, the way that + arguments are passed from parent to child in vfork() must change. + This bug has always been present, but was not visible with the + old strdup() way of passing arguments. + - vfork() problem: If we get to vfork() via system call, then we + need to clone some system call information so that the return form + the cloned system call works correctly. + - Fixes to tickless operation code, especially in alarm mode. From + Brandon Warhurst. + - Fix an important bug in the watchdog timer creation logic. + - Calling mq_timedreceived() with immediate timeout was getting stuck + and not timing out. Immediate timeout is achieved by setting absolute + timeout value to past time, for example abstime={ .tv_sec=0, + .tv_nsec=0 }. However absolute time was converted to relative time + using unsigned integer arithmetic and resulted large ticks count by + clock_abstime2ticks, instead of expected negative ticks value. + Change corrects clock_abstime2ticks() to return negative ticks, if + absolute time is in the past. From Jussi Kivilinna. + + * Memory Management: + + - Fix a place in the memory manager where it explicitly assumed that + the size of a pointer is 4 bytes. That assumption was OK if the + actual size is smaller but made the heap unstable when used with + the x86_64 host simulation. + - Granule Allocator: If the INTR granule allocator mode is enabled, + there is no semaphore to destroy. From Lorenz Meier. + + * Networking: + + - Network routing: I don't think that the net_route() function has + ever worked correctly. The source IP was updated in the match + struct instead of the route IP. From Brennan Ashton. + - Move and rename IP header flag definitions. The problem fixed here + is that there IP header flag definitions were not available when TCP + was disabled. The IP flags are used in ICMP and IGMP. + - Network routing: Refuse to perform routing table lookups for the + Broadcast IP address. From Brennan Ashton. + - Network routing: Add logic to netdev_findbyaddr() to return the + correct network device for the case where a broadcast + address is used. This change caused trivial ripples through other + files because additional parameters are required for + netdev_findbyaddr() when CONFIG_NET_MULTINIC. + + * File Systems/Block Drivers/MTD: + + - NXFFS Dump: Fix problems with redefinitions of fdbg macro. With the + fix to the syslog prototype, a LOG priority must now be the first + parameter. Fixed by replacing all occurrences of fdbg with + syslog(LOG_DEBUG, and eliminating the macro redefinitions. Noted + by Sebastien Lorquet. + - poll() was not waking up from signals (for example mq_notify() + events). From Jussi Kivilinna. + - poll(): Add proper handling for sem_timedwait errnos. From Jussi + Kivilinna. + - include/nuttx/fs/fs.h: Fix typo in conditional compilation. From + Alan Carvalho de Assis. + + * Graphics/Graphic-Related Drivers: + + - Remove warnings when CONFIG_NXTK_BORDERWIDTH is set to zero. From + Pierre-Noel Bouteville. + + * Common Drivers: + + - Make standard syslog and vsyslog POSIX compliant (also modify + non-standard syslog functions for compatibility). + - R/W buffering: Fix typo that can cause compilation error. + + * Atmel SAM3/4: + + - SAM4S: Add missing SPI0 clock configuration macro for the SAM4S. From spasbyspas. + + * Atmel SAM3/4 Drivers: + + - SAM4E-EK: Fix an error in a USART1 pin number. + + * Atmel SAMA5D3/4 Drivers: + + - SAMA5DF4: Fix several typos that will prevented EMAC1 from + initializing properly. + + * NXP LPC43xx: + + - Fixes to allow compile of lpc43_gpioint.c. From Brandon Warhurst. + + * STMicro STM32: + + - Add missing ADC pinmap definitions for the STM32 F103R from Martin + Lederhilger. + + * STMicro STM32 Drivers: + + - STM32 EXTI: Correct STM32 RTC EXTI bit definition. From Lazlo. + - STM32 IWDG, WWDG, DBGMCU: Fix watchdog stop bit usage. From Lazlo. + - STM32 OTGFS: Correct a typo in the STM32 OTGFS register bit definitions. + + * ARM: + + - ARM up_internal.h: Add protection from C++ name mangling in the + ARM up_internal.h. From Lorenz Meier. + + * MicroChip PIC32MX: + + - PIC32MX7: DEVCFG0 bit 2 must be set. Writing bit 2 as zero can + brick the CPU on some versions. From Cris Kvist. + + * C Library: + + - The implementation of access() as vararg macro has the issue that + any function call with the same name (even in a C++ class) will + match with it and result in a compile error. Replaced with a small + function. This resolves the compile issue, and shouldnt have + negative side effects for users of the function. From Lorenz Meier. + - The definition of strncpy() is that empty space should be zero- + filled, the change adds the zero filling (See the POSIX spec here: + http://pubs.opengroup.org/onlinepubs/7908799/xsh/strncpy.html). From + Lorenz Meier. + - limits.h: Remove the definition of INT_FAST32_MIN which is already + defined in stdint.h (the correct location). From Lorenz Meier. + + * Applications: + + - apps/: Correct everything under apps to use the corrected syslog + interfaces. Remove any non-portable uses of syslog. + - NSH: Fix ls -l output for regular files. + - NSH: Fix reversed in/out file closing in DD command when an error + occurs. From Ken Pettit. + - NSH: Add logic to restart the console wait if an error occurs + while reading from the console. In USB console startup, the logic + must be able to open the USB serial and receive 3 newlines. + However, it the USB driver is disconnected or otherwise fails before + the 3 newlines are received, the receive loop becomes a killer, + infinite loop, CPU hog. Noted by spasbyspas. + - Netutils: Fix memcpy of host address in netlib_gethostaddr(). From + Brennan Ashton. + - Netutils: If you make a DNS request before the DNS address it would + cause an assertion. The state of the IP setting is not something the + application should be aware of, it should only be concerned with + whether or not the name was resolved. From Brennan Ashton. + - Netutils: Fix md5 hashing when digest[$i] islower that 16. From + Sergey. + - Stack Monitor: Fix compile problems introduced when the syslog() + prototype changed; Also update Makefile for kernel build From + Radoslaw Adamczyk. + - Examples: Update NxTerm makefile for kernel-build issues. From + Radoslaw Adamczyk. + - Examples: Fixes to keypadtest from Pierre-Noel Bouteville. + - Examples: These examples all set the IP address of eth1 but the + netmask and gateway of eth0 if DHCP is enabled: discover, tcpecho, + webserver, xmlrpc. That can't be right. + +NuttX-7.7 +--------- + +The 107th release of NuttX, Version 7.7, was made on January 26, 2015, +and is available for download from the SourceForge website. Note +that release consists of two tarballs: nuttx-7.7.tar.gz and +apps-7.7.tar.gz. Both may be needed (see the top-level nuttx/README.txt +file for build information). + +Additional new features and extended functionality: + + * Core OS: + + - Task exit handling: Add logic to clean up after task_delete() or + pthread_cancel() if the task happens to be waiting on a semaphore + when was is cancelled. + - Stack coloration: Removed CONFIG_DEBUG_STACK and replaced it with + CONFIG_STACK_COLORATION that does the same thing but without enabling + debug. From David Sidrane. + + * Common Drivers: + + - Discrete joystick driver: Added an interface definition and upper + half driver for a discrete joystick device (where X/Y changes are + indicated with button presses). + - Analog joystick driver: Added an interface definition and upper + half driver for a analog joystick device (where X/Y positions are + sampled, numeric values). + - Add driver support for the ADXL345 accelerometer. From Alan + Carvalho de Assis + - Generic serial driver: Add watermark levels to the serial RX flow + control logic. Modify the rxflowcontrol method to accept the number + of bytes in the buffer and a boolean indication of which watermark + was crossed. + + * File Systems/Block Drivers/MTD: + + - Add procfs write support. From Ken Petit. + - Implemented wear-leveling in the SmartFS. From Ken Pettit. + - MMC/SD Interface: MMCSD SDIO: Add support for a new + SDWAIT_WRCOMPLETE condition. The previous logic used a busy-wait + loop to poll the card R1 status to determine when the card was + ready for the next transfer. That busy-wait can be quite long -- + up to hundreds of milliseconds. An alternative is to look the SD D0 + pin which will change state when the card is no longer busy. This + change avoids the busy-wait poll by reconfiguring the SD D0 pin as a + GPIO interrupt, then waiting for the card to become ready without + taking up CPU cycles. From David Sidrane. + + * Drivers: + + - Add support for a generic EEPROM driver that accesses EEPROM as a + character driver (vs. an MTD driver). From Sbastien Lorquet. + + * Graphics Support: + + - Many new fonts converted for use with NuttX and added by + Pierre-noel Bouteville + + * Networking: + + - IPv4 support is now conditioned on CONFIG_NET_IPv4. + - Implemented and verified IPv6 support conditioned on + CONFIG_NET_IPv6. Either IPv4 or IPv4 or both may be selected. + Sockets, of course, must be bound to one or the other. Added support + for IPv6 ioctls to manipulate IP addresses. + - Integrated support for ICMPv6 and the ICMPv6 Neighbor Discovery + Protocol and ICMPv6 ECHO request/reply needed to support ping logic. + - All Ethernet drivers: Modified to support. Most, however, are + still missing address filtering logic required for ICMPv6 Neighbor + Discovery Protocol. See + http://www.nuttx.org/doku.php?id=wiki:howtos:ipv6#ethernet_driver_requirements + - Also added missing raw/packet socket support to all Ethernet drivers. + + * Host Simulation: + + - Add a configuration build and test the Traveler first person game + using the simulator. + - Add an X11 mouse-based simulation of an analog joystick device + + * Atmel SAMA5D Boards: + + - Add analog Joystick shield support for the SAMA5D3 Xplained board. + + * Freescale KL Drivers: + + - Add GPIO interrupt capability for the KL architecture. From Alan + Carvalho de Assis + + * Freescale KL Boards: + + - Freedom-KL25Z: Add board support for the ADXL345 accelerometer. From + Alan Carvalho de Assis + - Freedom-KL25Z: Update the Freedom KL25Z board CC3000 support to use + the current CC300 interfaces. From Alan Carvalho de Assis + + * NXP LPC43xx Boards: + + - A port of NuttX to the LPC4357-EVB from Toby Duckworth. This port + is a leverage of the LPC3330-Xplorer port and still have a some + misinformation from that port that needs to be updated for the + LPC4357-EVB. + + * SiLabs EFM32 Drivers: + + - Serial: Add support for serial termios TCGET and TCSET. For the + moment, only set/get speed is implemented. From Pierre-noel + Bouteville. + - RMU: Add support for the EFM32 reset management unit (RMU). From + Pierre-noel Bouteville. + + * SiLabs EFM32 Boards: + + - Add support for timer/PWM on the EFM32GG. From Pierre-noel + Bouteville + + * STMicro STM32: + + - Enable support for the STM32 F102. From the PX4 team. + + * STMicro STM32 Drivers: + + - STM32 F429 LTDC: Add interface to perform hardware accelerated layer + operation. Provides access to a reference of a specific ltdc layer. + From Marco Krahl + - STM32 F429 LTDC support: Implemented LTDC framebuffer support for the + generic nuttx framebuffer interface. Also implements the interface to + perform hardware accelerated layer operation by the ltdc controller + and dma2d controller later. From Marco Krahl. + - STM32: Add support for the internal low speed clock (LSI) as a + source of the RTC clock. Some boards do not have the external + 32kKhz oscillator installed, for those boards we must fallback to + the crummy internal RC clock. From Kevin Hester + - STM32 SDIO: Add support for the new SDWAIT_WRCOMPLETE condition. + From David Sidrane + + * STMicro STM32 Boards: + + - Add a discrete Joystick support for the STM3210E-EVAL. + - Add analog Joystick shield support for the Nucleo F4x1RE boards. + - STM32 F429i-Disco: Add support for initializing of the ltdc + controller and the lcd device connected on the stm32f429i-disco. + From Marco Krahl. + - Removed the px4-v2_upstream configuration. This was not the + official configuration for the PX4 board and has led to confusion + by NuttX users. The board configuration also requires some ongoing + maintenance and customization to support ongoing PX4 testing and + evaluation. It is best retained the PX4 repositories where it can + be properly maintained and not in the upstream NuttX repository. + + * TI Tiva: + + - Add support for the TI Tiva TM4C 129X family. Some unverified + support for the TM4C 1294 is also in place. + + * TI Tiva Drivers: + + - Added support for Tiva I2C driver. Verified on the Tiva TM4C123G + and TM4C129X. + - Added a Tiva TM4C129X Ethernet driver. + - Add a timer library for generic support of Tiva timers + - Add a driver lower half for drivers/timer.c. Only 32-bit periodic + timers are supported. This provides userspace access to timers. + + * TI Tiva Boards: + + - TM4C123G Launchpad: Add initialization logic for an external AT24 + EEPROM. This is intended only to support testing of the Tiva I2C + driver. + - Board support for the Tiva DK-TM4C129x Connected Development Kit. + - DK-TMC129X: Add an IPv6-enabled NSH configuration. + + * C Library/Header Files: + + - Added support for a variadic ioctl() function. The ioctl() + interface is a non-standard, Unix interface. NuttX has always used + the older, three-parameter version. Most contemporary systems now, + however, use a variadic form of the ioctl() function. Added an + option to insert a shim layer to adapt the three-parameter ioctl() + to use the variadic interface form. Internally, the ioctl handling + is the same three-parameter logic. The only real complexity to the + shim is in how the system calls must be handled. + - Added sys/custom_file.h. Used when CUSTOM_FILE_IO is define and + avoids re-definition errors about the FILE define. From Thomas + Gruber via the PX4 repository + - Add CRC8 support to the C library. From Ken Pettit. + - math.h: Added support for the expm1 functions. From Brennan Ashton + + * Applications: + + - apps/examples/djoystick: Add a test of the discrete joystick + driver. + - apps/examples/ajoystick: Add a test of the analog joystick + driver. + - apps/examples/ltdc: Add ltdc test example. From Marco Krahl + - apps/system/lm75: Add a tiny application to read the temperature + from an LM-75 (or compatible) temperature sensor + - apps/examples/timer: Add a trivial test of the timer driver + + - apps/system/cu: Add a minimalist implementation of the 'cu' + terminal program (part of Taylor UUCP for ages). Using it, you can + simply open a serial port and interact with it. Using '~.' you can + leave the terminal program and drop back to nsh. This might come + in handy for people that have e.g. GSM modems, GPS receivers or + other devices with text based serial communications attached to + their Nuttx systems. From Harald Welte + - apps/interpreters/micropython: A port of Micro Python to NuttX. + Contributed by Dave Marples + + - apps/netutils/dnsclient: Can select to be either IPv4 or IPv6, but + not both (IPv6 still does not compile) + - apps/netutils/netlib: Add new library functions to manipulate IPv6 + addresses. + - apps/examples/nettest: Update test so that it can be used to test + IPv6 TCP sockets + - apps/examples/udp: The UDP test example has been extend to support + IPv6 domain sockets + + - apps/nshlib: Add logic to initialize IPv6 addresses + - apps/nshlib: Add the ping6 command to support checking IPv6 networks. + - apps/nshlib: Clean up network status presentation for IPv6 + +Efforts In Progress. The following are features that are partially +implemented but present in this release. They are not likely to be +completed soon. + + * IPv6. While basic IPv6 support was completed in NuttX-7.7, + there are lingering issues with getting IPv6 compatibility + with applications and network utilities. + + * Processes. Much of the work in this release is focused on the + realization of Unix-style user processes in NuttX. There is more to + be done, however. The full roadmap and status is available at: + http://www.nuttx.org/doku.php?id=wiki:nxinternal:memconfigs#the_roadmap_toward_processes + + * XMega: There are some fragments in place for an XMega port. That + port has not really started, however. + + * Galileo: Similarly, there are fragments in place for an Intel Galileo + port. The port probably will not happen (I gave my Galileo board away!). + +Bugfixes. Only the most critical bugfixes are listed here (see the +ChangeLog for the complete list of bugfixes and for additional, more +detailed bugfix information): + + * Core OS: + + - POSIX message queues: msg type should be char * not void * in + mq_send, mq_timedsend, mq_receive, and mq_timedreceive. Noted by + Pierre-Noel Bouteville + - POSIX message queues: In message queue creation return ENOSPC error + if size exceeds the configured size of pre-allocated messages; Use + ENOSPC vs ENOMEM per OpenGroup.org. From Pierre-Noel Bouteville. + - Task Names: strncpy() will not copy the terminating \0 into the + destination if the source is larger than the size of the + destination. Ensure that the last byte is always zero and let + strncpy() only copy CONFIG_TASK_NAME_SIZE bytes. The issue of + unterminated names can be observed in ps when creating a pthread + while CONFIG_TASK_NAME_SIZE is set to 8. From Daniel Willmann + + * Memory Management: + + - Granule allocator: Fixes some issues found by the PX4 team using + Coverity. From Pavel Krienko + + * Networking: + + - Several fixes correcting issues with the CC3000 networking. From + Jussi Kivilinna + - CC3000 Fix: Data can be unaligned. When dereferenced as an input + ntosh(), a bad value is returned. Reported by Alan Carvalho de + Assis + - Correct naming of fields in struct sockaddr_in6: sin6_port and + sin6_family, not sin_port and sin_family. + - accept(): Correct the value returned by accept() in the case where + net_lockingwait() is called. It was returning -1 and losing the + errno value.

From Lazlo + +NuttX-7.8 +--------- + +The 108th release of NuttX, Version 7.8, was made on February 11, 2015, +and is available for download from the SourceForge website. Note +that release consists of two tarballs: nuttx-7.8.tar.gz and +apps-7.8.tar.gz. Both may be needed (see the top-level nuttx/README.txt +file for build information). + +This release is primarily a bugfix release for the NuttX-7.7 version that +was release just two weeks prior. That release included substantial +modifications in the NuttX networking to accommodate support for IPv6. This +release follows close behind NuttX-7.7 in order to correct some the problems +discovered in that networking code. This release does, however, include a +small number of new features and bug fixes unrelated to NuttX networking. + +Additional new features and extended functionality: + + * Core OS: + + - Tickless Mode: added limit of maximum delay that can be request + by the scheduler tickless logic. This is necessary so that the + tickless logic does not request a delay beyond the capability of the + underlying hardware. From Macs Neklyudov. + + * Common Drivers: + + - VFS Unlink: Add an unlink method to both the character and block + driver interface. This is important because if the driver inode is + unlinked and there are no open references to the driver, then the + driver resources will be stranded. On the unlink call, the driver + has the opportunity (1) check if there an any open references, and + if not, (2) free the driver resources. + - Pipes and FIFOs: Implement the unlink method. If the pipe/FIFO is + unlinked, it will marked the pipe/FIFO as unlinked. If/when all + open references to the driver are closed, all of the driver + resources will be freed. + - Added an option to use the syslog'ing device as the system console. + This option enables a low-level, write-only console device at + /dev/console (similar to the low-level UART console device). From + Pierre-noel Bouteville. + + * File Systems/Block Drivers/MTD: + + - RAM/ROM disk: Add logic to dispose of the driver and RAM buffer + when the RAM disk has been unlinked and all open references to the + RAM disk have been closed. Add new parameters to romdisk() to + specify what should be done with the RAM/ROM buffer in this case -- + Should it be freed or not? Changed all calls to ramdisk() to use + these new parameters. + + * Networking: + + - Add support for local, Unix domain sockets. Support included for + both SOCK_STREAM and SOCK_DGRAM style local socket. + - UDP enhancement: Add UDP read-ahead support. In addition to + eliminating the main reason for lost UDP packets, then change + enables support for for poll/select on UDP sockets and also non- + blocking UDP sockets. From Macs Neklyudov. + - SLIP interface improvements. From Macs Neklyudov. + - IPv6 Neighbor Solicitation: Added logic to support verification + that we have the IPv6 address in the Neighbor Table before sending + any packets. If not, then the Neighbor Solicitation message is + sent. This feature is important because otherwise the first packet + sent to a remote peer will fail (it would have been replaced with a + Neighbor Solicitation). + - IPv6 Autonomous Auto-Configuration: Added support for sending + ICMPv6 Router Solicitation and receiving Router advertisement. The + local IPv6 address, mask, and router address are then auto-configured + from the response.. + - IPv6 Router Support: Add logic to behave like a router (if so + configured) only in the sense that NuttX will send the router + advertisement message in response to any received router solicitation + messages. Thus, one NuttX node in a network can configure the IPv6 + addresses of all other nodes in the network. + - Optional IPv6 address filtering added to all Ethernet drivers for + the all-routers multicast address. + + * Atmel AVR: + + - Added architecture support for the Atmel AVR ATMega1284P MCU. From + Jedi Tek'Unum. + + * Atmel AVR Boards: + + - Added support for the LowPowerLab MoteinoMEGA that is based on the + Atmel AVR ATMega1284P MCU. From Jedi Tek'Unum. + + * Atmel SAMA4: + + - Add support for Tickless mode of operation for the SAM4CM platform. + From Macs Neklyudov. + + * Atmel SAMA4 Drivers: + + - Ethernet: The SAM4E Ethernet driver can now be configuration to + perform all network processing on the work queue. This greatly + reduces the amount of interrupt level processing to service Ethernet + packets. + - SAM4E Ethernet: Add support multicast address matching and IPv6. + + * Atmel SAMA4 Boards: + + - SAM4E-EK: The nsh configuration now configures the Ethernet driver + for execution on the work thread. + + * Atmel SAMA5D Drivers: + + - SAMA5D4 Ethernet: The SAMA5D4 Ethernet driver can now be configuration + to perform all network processing on the work queue. This greatly + reduces the amount of interrupt level processing to service Ethernet + packets. + - SAMA5D3 and SAMA5D4 Ethernet: Add support multicast address matching + and IPv6. + + * Atmel SAMA5D Boards: + + - SAMA5D4-EK; Added a configuration to testing IPv6. + - SAMA5D4-EK: Converted the nsh and ipv6 configurations to configure + the Ethernet driver to use the work queue (vs. interrupt level + processing). + + * Freescale KL: + + - Add architectural support for the K26Z128VLH4 chip. From Derek B. Noonburg. + + * Freescale KL Boards: + + - Add board support for the Freedom KL26Z board. From Derek B. Noonburg. + + * NXP LPC17xx Drivers: + + - Ethernet: Add support multicast address matching and IPv6. + + * SiLabs EFM32: + + - Add configurable option to unconditionally enable LE clocking. Even + you don't use core clock LE as source for LFA or LFB, to read are + write any register not clocked by HFPERCLK or HFCORECLK, HFCORECLKLE + should be enabled. From Pierre-noel Bouteville. + + * SiLabs EFM32 Drivers: + + - EFM32 RTC: RTC driver using BURTC. From Pierre-Noel Bouteville. + + * STMicro STM32 Drivers: + + - AES: Add driver for STM32L162XX AES peripheral. From Juha Niskanen. + - Ethernet: The STM32 Ethernet driver can now be configuration to + perform all network processing on the work queue. This greatly + reduces the amount of interrupt level processing to service Ethernet + packets. + - Ethernet: Add support multicast address matching and IPv6. + + * STMicro STM32 Boards: + + - Added an IPv6 configuration for the STM32F4-Discovery board (with the + STM32-DISCO_BB base board). + - Converted all STM32F4-Discovery configurations (with base board) to + configure the Ethernet driver to use the work queue (vs. interrupt + level processing). + + * TI Tiva Drivers: + + - Added support for TM4C123G timers. From Calvin Maguranis. + - Added a Tiva ADC driver. From Calvin Maguranis. + + * TI Tiva Boards: + + - Added TM4C123G timers on the TM4C123G Launchpad. From Calvin Maguranis. + - Added Tiva ADC support to the TM4C123G-Launchpad. From Calvin Maguranis. + + * C Library/Header Files: + + - Math Library: Added support for inverse hyperbolic functions, + isfinite(), error functions, nan(), copysign(), and trunc() + functions. From Brennan Ashton. + + * Applications: + + - apps/examples/ustream: Add a simple test of Unix domain stream + sockets. + - apps/examples/udgram: Add a simple test of Unix domain datagram + sockets. + - apps/netutils/netlib: Add utilities to convert to/from prefix + lengths from/to 128-bit network masks. + - apps/nshlib: Modify the NSH IPv6 ifconfig command to show the more + standard post-pended prefix value, rather than the full 128-bit + netmask. + +Efforts In Progress. The following are features that are partially +implemented but present in this release. They are not likely to be +completed soon. + + * Processes. Much of the work in this release is focused on the + realization of Unix-style user processes in NuttX. There is more to + be done, however. The full roadmap and status is available at: + http://www.nuttx.org/doku.php?id=wiki:nxinternal:memconfigs#the_roadmap_toward_processes + + * XMega: There are some fragments in place for an XMega port. That + port has not really started, however. + +Bugfixes. Only the most critical bugfixes are listed here (see the +ChangeLog for the complete list of bugfixes and for additional, more +detailed bugfix information): + + * Core OS: + + - Work Queues: Fix a backward calculation when determining the time + to the next interesting event. . From Liio Chen via the PX4 + repository. + - clock_systimespec(): Fixes for compilation errors in certain + configurations. From Macs Neklyudov. + + * Graphics + + - Fixed a problem with one of the font files. From Pierre-noel Bouteville. + + * Networking: + + - IOB Deadlock: There were issues with the TCP write-ahead buffering + if CONFIG_NET_NOINTS was enabled: There is a possibility of + deadlocks in certain timing conditions: The network should never + wait for TCP read-ahead buffering space to be available. It should + drop the packets immediately if no buffering is available. This was + fixed by duplicating most of the IOB interfaces: The versions that + waited are still present (like iob_alloc()), but now there are non- + waiting versions of the same interfaces (like iob_tryalloc()). The + TCP read-ahead logic now uses only these non-waiting interfaces. + - TCP Deadlock: Fix another deadlock when CONFIG_NET_NOINTS is enabled. + tcp_write_buffer_alloc() calls sem_wait() with network locked. That + worked if CONFIG_NET_NOINTS was not defined because interrupts are + automatically restored when the wait happens. But with + CONFIG_NET_NOINTS=y, the wait blocks with the network locked -- bad + style and also can lead to a deadlock condition. + - ARP response waiting: Fixes another CONFIG_NET_NOINTS issue. When + called sem_timedwait() with the network locked, the network stays + locked while we wait which is not what we want (without CONFIG_NET_NOINTS, + interrupts are re-enabled while we wait and all is well). + - TCP accept(): Fix a major TCP bug introduced with the NuttX-7.7 + IPv6 changes: Some connection logic was reordered; setting the + socket as 'connected' got moved to BEFORE the point where the check + was made if the socket was already connected. The resulting behavior + was odd: Telnet would connect, but then when you exit and reconnect, + it would fail to connect. But then if try again, it would connect + okay. So the symptom was connect-fail-connect-fail-... + - Lots of build problems introduced into multiple NIC support with the + IPv6 changes of NuttX-7.7. Many places where conditional logic based + on CONFIG_NETDEV_MULTINIC is confused with CONFIG_NET_MULTILINK. + Lots of code changed with IPv6 that was never compiled with MULTINIC + enabled. + + * Common Drivers: + + - Pipes and FIFOs: Fix a race condition between FIFO buffer operations + and the opening and closing of FIFOs which necessary when the FIFOs + are used to support Unix domain, datagram sockets. The default + policy is the deallocate FIFO buffering when the last client closes + the pipe. When when used for datagram communications, packets left + in the FIFO will be lost. Some like UDP read-ahead is needed: The + buffered data in the FIFO needs to be retained until the reader gets + a chance to re-open the FIFO. Added an ioctl (PIPEIOC_POLICY) to + control the buffer policy. Default (0) is the legacy behavior; Unix + domain datagram logic sets the alternative policy so that the packet + data persists after the FIFO is closed. + - RAMTRON: Table of parts is not terminated properly if + CONFIG_RAMTRON_FRAM_NON_JEDEC is not defined. Noted by David + Sidrane. + + * All Architectures: + + - Removed all occurrences of up_maskack_irq() that disables interrupts + with up_ack_irq() that only acknowledges the interrupts. This is only + used in interrupt decoding logic. Also remove the logic that + unconditionally re-enables interrupts with the interrupt exits. This + interferes with the drivers ability to control the interrupt state. + This is a necessary, sweeping, global change and unfortunately + impossible to test. + + * ARM + + - ARMv7-A and ARMv7-M memcpy(): Optimized ARM assembly language + memcpy's were not returning a value in R0 they are required to do. + From David Sidrane. + - ARMv7-A interrupt handler should not automatically re-enable interrupts + on interrupt return. That interferes with the driver's ability to + manage interrupts. Analogous change made to all other architectures + as well (ARM7, ARM9, HC, SH, x86, z16, z80, etc,. See above.). + + * STMicro STM32: + + - GPIO Interrupts: Disabling any of EXTI 5-9 interrupts was disabling + interrupts for all EXTI 5-9. Same issue with EXTI 10-15. From Jussi + Kivilinna. + + * STMicro STM32 Drivers: + + - RTCC: Fix for recent changes that caused compilation failrues with + STM32L15XX configurations. From Jussi Kivilinna. + - SPI: The source clock for SPI 4,5, and 6 should be PCLK2, not PCLK1 + (for F411, F427, and F429). Per David Sidrane. + + * C Library/Header Files: + + - execl(): Fix bad logic in counting the number of arguments. + execl() parameter passing could never have worked. Noted by + Pierre-noel Bouteville. + + * Applications: + + - Fix for building with parallel make. Build-server sometimes failed + 'make -j24' with errors in the builtin line or or sometimes silently + succeeds but generated builds that contain a random subset of + configured NuttX applications. There are two root causes for this: + (1) Recipes for building builtin_list.h and builtin_proto.h are + not linearizable, and (2) Nothing ensures that 'make context' is run + first for apps/builtin. This change address both issues. From Juha + Niskanen. + +NuttX-7.9 +--------- + +The 109th release of NuttX, Version 7.9, was made on April 14, 2015, +and is available for download from the SourceForge website. Note +that release consists of two tarballs: nuttx-7.9.tar.gz and +apps-7.9.tar.gz. Both may be needed (see the top-level nuttx/README.txt +file for build information). + +Additional new features and extended functionality: + + * Core OS: + + - Assertions: Add support for dumping board-specific information on + assertions. From David Sidrane. + - boardctl(): : Add a new non-standard OS interface called boardctl(). + This is similar to a driver IOCTL call. But this is an IOCTL call + directly on the board logic. This function will eventually replace + all of the ad hoc OS interfaces that are current used to perform + application specific initialization and application driver test + configuration. It essentially formalizes and institutionalizes + these rogue interface in to at least a single crazy call. + + * Graphics: + + - Line Joins: Line drawing graphic functions now take an argument that + will draw a circular "cap" on the ends of lines to support cleaner + joining of lines segments.. + + * Common Drivers: + + - SPI iInterface: Add an SPIDEV_USER so that there can be board- + specific definitions of SPI devices. + - I2C Interface: Add a user provided void * argument to the I2C + callback method for the I2C slave interface. Suggested by Nate + Weibley. + - AT24 EEPROM Driver: Add support for (1) the byte-oriented read() + method, (2) devices that have extended memory regions, and (3) + devices that use 8-bit addressing. + - Freescale MPL115A barometer: Add driver for the Freescale MPL115A + barometer. From Alan Carvalho de Assis. + - CS2100-CP: Add a driver for the CS2100-CP Fractional-N Multipler + chip. + - RTC IOCTls: Added the definitions of a driver based RTC interfaces + and RTC upper half driver. + + * File Systems/Block Drivers/MTD: + + - umount2(): Added to support un-mount flags. umount() is now a macro + that just calls umount2() with flags = 0. + - File system interface: Pass the umount2() flags to every unbind() + implementation. That is where the decision to umount or not and how + to umount will be made. + - FAT unbind: Add support for umount2(target, MNT_FORCE) in the FAT + file system. + + * Networking: + + - netdev_register(): Improve the network device registration logic. + When multiple link types are used, modify how each interface number + is assigned to the device name by incrementing the device number + individually for each interface link type. From Max Neklyudov. + - Add TUN network device. Used to support the Netutils PPPD + implementation. From Max Neklyudov. + + * ARMv7-M + + - ARM Cortex-M7: Add basic support for the Cortex-M7 architecture. + - ARMv7 Common Lazy Exception handling. Add common support for lazy + FPU state saving. MCU-specific lazy FPU saving was already in place. + This change just makes the code share-able. + + * Atmel SAMA5D3/4 Drivers: + + - SAMA5 Serial: Backport support for flowcontrol and termios from + SAM3/4. + + * Atmel SAMV7: + + - Atmel SAMV7: Add architecture support for the Atmel SAMV7 family + (Cortex-M7) + + * Atmel SAMV7 Boards: + + - Atmel SAMV71 Xplained Ultra: Add board support for this SAMV7 board. + This initialize release includes support for: SDRAM, TWI/I2C, SPI, + Ethernet, HSMCI, DMA, GPIOs, UARTs, AT24 EEPROM and the maXTouch + Xplained Pro LCD. Drivers are available for SSC/I2C, the WM8904, + the maXTouch trouchscreen, and USB device but have not yet been + fully integrated in this release. + + * SiLabs EFM32 Drivers: + + - EFM32 USB Device is now functional with the efforts of From Pierre- + noel Bouteville. + - EFM32 I2C: Add I2C driver. From Pierre-noel Bouteville. + + * STMicro STM32: + + - STM32F372/F373: Adds architecture support for this STM32 parts. + Tested on STM32F373CC. Contributed by Marten Svanfeldt. + + * STMicro STM32 Drivers: + + - STM32 RTCC: Break out a new internal interface, stm32_rtc_setdatetime(). + This eliminates some un-necessary time conversions. From Freddie Chopin. + - STM32 RTCC: Add an implementation of the RTC lower half interface + for the STM32. + - STM32 RTCC: Extend the RTC interface to support reading subseconds. + From Jussi Kivilinna. + - STM32 BBSRAM: Adds the ability to use the STM32F2 and STM32F4 Battery + Backed SRAM in the file system. With an option to Save Panic context + to one of the files. From David Sidrane. + + * STMicro STM32 Boards: + + - Olimexino-STM32: Board support for the Olimexino STM32 board from David + Sidrane. + - Viewtool-STM32F107: Add support for an optional, add-on Freescale + MPL115A baramoter. From Alan Carvalho de Assis. + + * TI Tiva: + + - TM4C1294: Add support for the TM4C1294. Contributed by Frank Sautter. + + * TI Tiva Drivers: + + - Tiva ADC: Updated files to allow for ADC and PWM triggering by a + timer. Refactoring of ADC implementation. From Calvin Maguranis. + - Tiva Timer: Refactoring by Calvin Maguranis + + * TI Tiva Boards: + + - TM4C123G-launchpad: Add ADC support. From Calvin Maguranis. + - TM4C123G-launchpad: Add board button interrupt support. From Calvin + Maguranis. + - TM4C1294 Launchpad: Add support for the TM4C1294 Launchpad. + Contributed by Frank Sautter. + + * Microchip PIC32 + + - PIC32MZ: Add architectural support for the PIC32MZ (MIPS32 M14k). + Includes contributions from Kristopher Tate. + + * Microchip PIC32MZ Boards + + - PIC32MZ Starter Kit: Add basic board support for the PIC32MZ. + Includes contributions from David Sidrane. + + * C Library/Header Files: + + - gettimeofday(): This function is no longer a core OS interface. It + is only a wrapper around clock_settime(). + - settimeofday(): Added. gettimeofday has been deprecated in POSIX + 2008. settimeofday() was never part of POSIX, but I decided to add + it to libc as well just for symmetry. + - Day-of-Week: Add CONFIG_TIME_EXTENDED to support the last 3 members + of the tm struct and support for filling them in with the day of the + week. From David Sidrane. + - sighold(), sigrelse(), sigignore(), sigset() and sigpause(): New + signal handling functions. + - sys/select.h: Extend the fd_set type definition so that it can + handle more than 32 descriptors (if so configured). From Max + Neklyudov. + - netdb.h: Add a mostly-commented-out version of the standard netdb.h + header file. + - include/nuttx/board.h: Remove common board function prototypes from + other files and consolidate them in this new header file. + + * Applications: + + - OS test: Improved error checking for sem_timedwait() from Juha + Niskanen. + - OS test: Add a simple test of sigprocmask, sighold, and sigrelse. + - PPPD test: Add PPPD test case. Split out from the PPPD daemon by + Brennan Ashton. + - Netutils: Add a PPP daemon. From Max Neklyudov. + - NSH: NSH initialization now calls boardctl(BOARDIOC_INIT) instead + of nsh_archinitialize(). Remove support for CONFIG_NSH_ARCHMAC. + It is not used and there are better ways to do that operation. + - NSH: Allow NSH 'date' command with no hardware RTC. This command + is useful without an RTC too. Also, this permits testing on the + simulator which never has an RTC. + - apps/examples/: Several tests changed (touchscreen adc, pwm, + graphics). No longer call directly into the OS, but rather + indirectly via boardctl(). + - Modbus: Includes extensions to support RTU master mode by + Armink(383016632@qq.com): https://github.com/armink/FreeModbus_Slave-Master-RTT-STM32. + Ported to NuttX by Darcy Gong. + - TZ database: All logic to build timezone database needed for + localtime() support. Does not do much else yet. + +Efforts In Progress. The following are features that are partially +implemented but present in this release. They are not likely to be +completed soon. + + * Processes. Much of the work in this release is focused on the + realization of Unix-style user processes in NuttX. There is more to + be done, however. The full roadmap and status is available at: + http://www.nuttx.org/doku.php?id=wiki:nxinternal:memconfigs#the_roadmap_toward_processes + + * XMega: There are some fragments in place for an XMega port. That + port has not really started, however. + +Bugfixes. Only the most critical bugfixes are listed here (see the +ChangeLog for the complete list of bugfixes and for additional, more +detailed bugfix information): + + * Core OS: + + - atexit(): Fix compile failure due to reference to undefined variable + in certain configurations. From Juha Niskanen. + - syscalls: Last changes to message queue prototypes did not make it + into call gate logic. Some additional errors had crept as well since + the system calls are seldom used. + - waitpid(): Do not use uninitialized boolean in waitpid(). From Juha + Niskanen. + - Timing functions: Fix some nanosecond comparisons. Comparisons should + be greater than OR EQUAL TO 1000000000 for maximum value of nanoseconds + in struct tm. From Juha Niskanen. + - Time initialization: Fix an error in time initialization when there + is no RTC and the time is initialized from a fixed configured value. + The call to clock_calendar2utc() was returning the time in units of + seconds. The initialization logic, however, was expecting to get + time in units of days. This problem has been there forever but + obviously has not significant impact to behavior in systems where + time is not visible. + - mq_timedsend(): Should not check for valid time if there is space + in the message queue. Noted by Freddie Chopin. + - select() and sem_timedwait(): Fix places where the errno value was + being overwritten by subsequent actions so that the returned errno + value was incorrect. From Max Neklyudov. + - clock_systimer64(): Fix a problem in clock_systimer64 that occurs + when (1) the 64-bit system time is enabled, and (2) the value of + CONFIG_USEC_PER_TICK is less than 1 milliseconds (such as when using + the tickless mode of operation). In that case, the conversion of + time to 64-bit millisecond value in clock_systmer64() causes some + bad times to be returned. Time was converted to milliseconds, then + to configured ticks. Precision was lost in the millisecond + conversion. The fix is to first convert time to a 64-bit microsecond + value, then to the configured tick value. Noted by David Sidrane. + - clock_systimespec(): When an RTC is used clock_systimespec() must + subtract the basetime from the returned time. It needs to return + the time since power up, no the current time. Issue noted by Max + Neklyudov. + - AIO: correct some backward tests in aio_read() and aio_write(): + Socket descriptors have higher numbers than file descriptors. In + aio_contain(), Copy u.ptr (void *) when initializing aioc and not + the case specific u.aioc_filep. From Michal Ulianko. + + * File Systems/Block Drivers/MTD: + + - procfs: Fix potential NULL pointer dereference of 'node'. From + Juha Niskanen. + - FAT: fat_unbind() was accessing 'fs->fs_sem' after freeing the 'fs' + struct. From Juha Niskanen. + - mkfatfs: Use DMA memory for mkfatfs when needed. This makes mkfatfs + use fat_dma_alloc() when CONFIG_FAT_DMAMEMORY is set. This is needed + to ensure mkfatfs operates with boards that use DMA for microSD. + From Andrew Tridgell via the PX4/NuttX repository. + - FAT unmount: Fix a bug in the FAT unbind() logic. There were + problems with the way certain internal list handling was + implemented. The end result is that newly opened or cloned file + structures were never being added to the list of open files. So + when the unmount() happens, it always looked like there were not + open files and a crash could ensue. + - FAT mounting: Fix misthink when CONFIG_ENDIAN_BIG=y. From Lwazi Dube. + + * Common Drivers: + + - CAN upper half driver: Some lines had to be reordered in the can_open + function otherwise the open count will only be incremented from 0 to + 1. This caused problems when trying to open the can bus from two + different tasks. SourceForge Patch #46. + + * Crypto: + + - crypto: Fix issues when AES support was added for the STM32L1. + From Juha Niskanen. + + * Networking: + + - Network initialization: Divide net_intiialize() into net_setup() and + net_initialize() to solve a chicken-and-egg problem. net_setup() + must be called before up_initialize() is called so that networking + data structures are ready to register new network devices. + net_initialize() now does only timer related operations and is + called AFTER up_initialize() where the timers are configured. + Problem noted by Max Neklyudov. + - netdev_unregister(): Fix a list handling error. From Max Neklyudov. + - Socket dup: Do not call sockfd_socket() twice. From Juha Niskanen. + + * Common Drivers: + + - max11802 touchscreen: Fix possible unmatched IRQ restore (not + normally a problem, but could happen in certain configurations). + Noted by Juha Niskanen. + - MMCSD SPI Multi-block transfers: ACMD23 must be preceded with CMD55 + command as any other ACMD commands. Also, after the block reading + wait loop must be inserted before writing the next block of data to + the sd card. From Dmitry Nikolaev via Jussi Kivilinna. + - MMCSD SDIO: Fix some bad logic when file system debug is turned on: + Arguments to syslog were missing so that garbage was being printed. + - Common upper-half serial driver: Report correct number of bytes free + in serial buffer with FIONWRITE. From Sami Pelkonen via Jussi Kivilinna. + - Pipes/Fifos: Fix zero-lenth writes to pipes/FIFOs. From Jussi Kivilinna. + - USB device MSC: Add NULL pointer check. From Juha Niskanen. + - BCH driver: Avoid NULL pointer dereference when bch->refs == 255. + From Juha Niskanen. + - Various drivers: The inode unlink method should not be support if + operations on the root pseudo-filesystem are disabled. + + * ARMv7-M + + - ARMv7M MPU: Bad syntax in ARMv7-M MPU logic would cause failure to + write the correct value to the MPU_RASR register. From Juha Niskanen. + + * Atmel SAM3/4 Drivers: + + - SAM3/4 Serial TERMIOS: A side-effect of changing serial settings + via TERMIOS (such as tcsetattr) is that serial interrupts were being + left disabled. This is not a problem if the serial configuration is + changed when there are no open references to the serial device. In + that case, serial interrupts are disabled and will not be enabled + enabled until the serial device is first opened. But it is fatal if + the serial device is already opened and if there is a task waiting + to receive data. In that case, the side-effect of disabling + interrupts is fatal: That task is then left hanging with interrupts + disabled. + - SAM3/4 Serial: The IMR register is read-only. This means that + sam_restoreints() did not actually re-enable UART interrupts + (Fortunately, that function was not being used up to this point). + - SAMA5 HSMCI: Fix a bug in SAMA5 HSMCI. The bitfield mask and shift + values were reversed resulting in a trashed value for the number of + blocks in the BLOCKR register. This was sufficient to prevent DMA + writes from working. + + * Atmel SAMA5 Drivers: + + - SAMA5 Timer/Counter: Fix typos in timer/counter header file. From + Bob Doiron. + + * STMicro STM32 Drivers: + + - STM32 PWR and RTC: Changes to support fully write protecting the + backup domain. N.B. stm32_pwr_enablebkp did not account for the delay + from enable to the domain being writable. The KISS solution is a + up_udelay. A more complex solution would be a negated write test + with restore. From David Sidrane. + - STM32 SPI: Add missing SPI callback functions to the STM32 SPI + driver. From Freddie Chopin. + - STM32 I2C: Add missing NULL check. From Juha Niskanen. + - STM32 USB device: Fix stale initialization invalidating later NULL + check. From Juha Niskanen. + - STM32 UART: Fix RX DMA setup for UART5. From Jussi Kivilinna. + - STM32 UART: Make input hardware flow-control work with RX DMA. From + Jussi Kivilinna. + - STM32 RTC and clock control: The STM32F4Discovery board doesn't + come with a Low speed external oscillator so the default LSE source + for the RTC doesn't work. In stm32_rtcc.c the up_rtc_initialize() + logic doesn't work with the LSI. The check on RTC_MAGIC on the BK0R + register lead to rtc_setup() call that rightfully enables the LSI + clock; but the next times, when the rtc is already setup, the + rtc_resume() call does NOT start the LSI clock! The right place to + put LSE/LSI initialization is inside stm32_stdclockconfig() in + stm32fxxxxx_rcc.c. Doing this I checked the possible uses of the + LSI and the LSE sources: the LSI can be used for RTC and/or the + IWDG, while the LSE only for the RTC (and to output the MCO1 pin). + This change is not verifed for any other platforms. From Leo + Aloe3132 + + * Tiva Drivers: + + - Tiva GPIO driver needed small fixes in the configuration routines and + discovered false-positive bugs in interrupt testing: interrupts are + now verified to actually be working reliably. From Calvin Maguranis . + + * MIPS32: + + - mips32/Toolchain.mk: Current Pinguino toolchain uses the prefix p32- + instead of mips-. + + * C Library/Header Files: + + - sigaddset() and sigdelset(): Need to set errno if a bad signal + number is received. + - sfrtime(): Missing implementation of %C in sfrtime() C (was being + treated as %y). From Freddie Chopin. + - pthread.h: Fix PTHREAD_COND_INITIALIZER. + - ungetc.c: Fix NULL pointer dereference in ungetc() if 'stream' was + NULL, 'stream->fs_oflags' was evaluated. From Juha Niskanen. + - Fixes to asinh(), atanh(), and sinh(): The 'basic' expansions all + exhibited bad cancellation errors near zero (<= 1E-10). This can be + easily seen e.g. with x = 1E-30, the results are all zero though they + should be extremely close to x. The cutoff values (1E-5, 1E-9) are + chosen so that the next term in the Taylor series is negligible (for + double). Functions could maybe be optimized to use only first term (x) + and a smaller cutoff, just bigger than where the cancellation occurs + - localtime(): Inconsistent configuration name: CONFIG_LIBC_TZDIR vs + CONFIG_LIBC_TZ_TZDIR. Former wins. + + * Applications: + + - Modbus: Fix some compile problems when TCP is enabled. + +NuttX-7.10 +---------- + +The 110th release of NuttX, Version 7.10, was made on June 9, 2015, +and is available for download from the SourceForge website. Note +that release consists of two tarballs: nuttx-7.10.tar.gz and +apps-7.10.tar.gz. Both may be needed (see the top-level nuttx/README.txt +file for build information). + +Additional new features and extended functionality: + + * Binary Loader: + + - ARMv-7M, binfmt/, STM32: Add support uClibc++ exceptions. This + involved additional handling for relative relation types, additional + support for unwinding, as well as additional changes. The + culmination of a big effort from Leo Aloe3132. + + * Graphics/Graphic Drivers: + + - RA8875 LCD driver contributed by Marten Svanfeldt. + + * File Systems/Block Drivers/MTD: + + - Union File System: Add support for a union file system that can be + used to overlay and merge the content of two mounted file systems. + + * USB Host: + + - USB Hub Support: Bring in USB hub-related files from + https://github.com/kaushalparikh/nuttx. This is the work of Kaushal + Parikh. This is quite a bit more hub logic was needed in before the + USB hub support was fully functional. This involved changing many + USB host controller driver interfaces and modifications to many + drivers. + - USB host CDC/ACM class driver: Added initial implementation of a + host-side CDC/ACM driver. Initial version was a great learning + experience, but probably should be partially redesigned (as + discussed in the top-level TODO file). + - IPv6 Routing: Complete implementation of the IPv6 routing logic. + From Max Neklyudov. + + * Networking: + + - Local Sockets: Add poll support for Unix stream sockets. From Jussi + Kivilinna. + - net/: ARP, ICMP, ICMPv6, PKT, TCP, and UDP now all receive event + notifications from both network device packet processing, but now + also from Device-specific events such as when the network goes down. + The device notification callback structure is now supports dual + linkages so that the client can receive notifications from both + source; The device structure now includes a list of clients that + want to receive device related notifications. This prevents network + actions from hanging when the device goes down and will be an + essential part of future support for removable network devices. + Some of the core logic was contributed by Max Neklyudov. + - TUN: Misc. improvements to the TUN driver, mostly related to poll(). + Also several bugfixes. From Max Neklyudov. + + * Simulation Platform: + + - Simulator: Add logic to test localtime and TZ database. See + apps/system/README.txt for info. + - Simulation: Add a configuration for testing the Union File System. + + * Calypso: + + - Calypso Compal-E86: Updates for execution out of FLASH on the C139 + phone. From Craig Comstock. + + * Atmel SAMD/L: + + - SAML21 Support: And chip definitions, configuration framework, + memory map and pin configuration files for SAML21 support. + + * Atmel SAMD/L Boards: + + - SAML21-Xplained: Add a board support for the SAML21 Xplained Pro. + This is based on the similar SAMD20 Xplained Pro board. + + * Freescale/NXP KL: + + - KL25Z64: Added support for the KL25Z64. The KL25Z64 is a lower + memory variant of the KL25Z128 and is used on the Teensy LC. From + Michael as SourceForge patch 50. + + * Freescale/NXP KL Boards: + + - Teensy-LC: Add board support for the Teensy LC board. Support is + based off the Freedom KL25Z board. LED, PWM, and UART0 have been + tested. The SPI pins are mapped correctly but have not yet been + tested. From Michael Hope as SourceForge patch 51. + + * NXP LPC111x: + + - LPC111x: Support for the LPC11xx family (the LPC1115 MCU in + particular). Contributed by Alan Carvalho de Assis. + + * NXP LPC111x Boards: + + - LPCXpresso LPC1115: Support for the LPCXpression LPC1115 + board. Contributed by Alan Carvalho de Assis. + + * NXP LPC17xx Drivers: + + - LPC17xx Ethernet: Add support for the Micrel KSZ8041 PHY to the + LPC17xx Ethernet driver. + + * NXP LPC17xx Boards: + + - Lincoln60: Add a network enabled configuration for the Lincoln60 + board. + + * Atmel SAM3/4 Drivers: + + - SAM4CM: Add support for optical mode for the SAM4CM UART1. From + Max Neklyudov. + + * Freescale (NXP) Kinetis: + + - Kinetis K20: Basic support for the Kinetis K20 architecture. Taken + from PX4. This is the work of Jakob Odersky. + + * Atmel SAMV7 Boards: + + - SAMV71-Xplained w/maXTouch Xplained Pro: A TWIHS fix was the last + barrier to getting the touchscreen working in the maXTouch Xplained + Pro LCD. Added the NxWM integrated graphics demonstration + configuration. + + * STMicro STM32: + + - STM32: Added support for STM32F302K8 and STM32F302K6. From Ben Dyer + via PX4/David Sidrane. + - STM32F205RG: Add basic support for the STM32F205RG. From SourceForge + Ticket 40 (anonymous, 2015-05-31). + - STM32 F3: Add DBGMCU register definitions for the F3 family. From + Greg Meiste. + + * STMicro STM32 Drivers: + + - STM32 LCDC: Defined a second interface for the dma2d controller. + LTDC only controls the display visibility but the DMA2D controller + changes the content of the frame buffer (buffer of the layer). From + Marco Krahl. + - STM32 PVD: Added support for STM32's Programmable Voltage Detector + (PVD) feature. By Dmitry Nikolaev, submitted by Juha Niskanen. + + * STMicro STM32 Boards: + + - STM32F429i-Disco: Add support for the new DMA2D features to the LTDC + configuration. From Marco Krahl. + + * TI Tiva Boards: + + - TM4C1294 Launchpad: Added TM4C1294NCPDT EN0_LED2 (10/100-Base-Tx); + removed all booster pack pin definitions. From Frank Sautter. + + * C Library/Header Files: + + - libc: Add an option to disable support for long long formats in + lib_vsprintf(). On very tiny platforms, this reduces the footprint + by omitting large libgcc.a libraries to perform the 64-bit + arithmetic operations. From Alan Carvalho de Assis. + + * Applications: apps/system: + + - nuttx/zoneinfo: Add logic to build a ROMFS file system + containing the timezone data. + + * Applications: apps/nshlib: + + - Add poll support for Unix stream sockets. From Jussi Kivilinna. + - Enhancements to NSH ifconfig for case of multi-link operation, TUN + device and local connections. From Max Neklyudov. + - Enhanced output to NSH ping command from Max Neklyudov. + - The NSH mount command now recognizes the Union filesystem type when + listing mounted file systems. + + * Applications: apps/netutils: + + - apps/netutils/thttpd/ and apps/examples/thttpd/: Add support for + using binfs/ with the Union FS instead of NXFLAT. NXFLAT is + probably the better solution but recently compiler changes make it + unusable. binfs or ELF are fallback binary formats. This commit + adds an option to use binfs with the Union FS. + + * Applications: apps/examples: + + - Modify/simpify apps/examples build files. From Roman Saveljev. + - apps/examples/ltdc: Add testing support for the STM32 LTDC's 2D DMA. + From Marco Krahl. + - apps/examples/ostest: Add a test of nested signals. There are no + failures to handle signals but neither am I getting any nested signal + handling. + - apps/examples/elf: Add configuration options to support building the + hello++4 example that depends upon having uClibc++ available. Also + add hello++5 to the ELF example From Leo aloe3132. + - apps/examples/unionfs: Add a test of the union file system to + apps/examples. + +Efforts In Progress. The following are features that are partially +implemented but present in this release. They are not likely to be +completed soon. + + * Processes. Much of the work in this release is focused on the + realization of Unix-style user processes in NuttX. There is more to + be done, however. The full roadmap and status is available at: + http://www.nuttx.org/doku.php?id=wiki:nxinternal:memconfigs#the_roadmap_toward_processes + + * XMega: There are some fragments in place for an XMega port. That + port has not really started, however. + +Bugfixes. Only the most critical bugfixes are listed here (see the +ChangeLog for the complete list of bugfixes and for additional, more +detailed bugfix information): + + * Core OS: + + - boardctl(): Add missing case causing that caused failures of PWM + test. + - pthread_kill(): Re-implemented pthread_kill(). It was just a simple + wrapper around kill() but since the correct dispatching of signals + for multi-threaded task groups has been implemented, calling kill() + does not do what pthread_kill() is supposed to do. The corrected + implementation of pthread_kill() will direct the signal specifically + to the specific pthread and no other. + - uint32_t callbacks: Update the type passed to watchdog timer + handlers. Using uint32_t is a problem for 64-bit machines because + it it too small to pass a pointer. uintptr_t is a more appropriate + type. + - mq_timedreceive(): move the location where the errno value is set; + the ETIMEDOUT errno setting was being overwritten by subsequent + actions before returning. Noted by Freddie Chopin. + - POSIX message queues: Move mq_setattr() and mq_getattr() from + nuttx/libc/mqueue to nuttx/sched/mqueue. Also add syscall support + for mq_setattr() and mq_getattr(). This is necessary in protected + and kernel builds because in those cases the message queue + structure is protected and cannot be accessed directly from user + mode code. + + * File Systems/Block Drivers/MTD: + + - MTD: Increase the size of the fields in the geometry structure + (again) to support larger FLASH sizes. Needed by Sebastien Lorquet. + + * Common Drivers: + + - poll(): Fix resource leak and memory corruption on poll failure. + From Jussi Kivilinna. + + * USB Host: + + - LPC31xx and SAMA5Dx EHCI: Fix cache related problem in LPC31 and + SAMA5Dx EHCI drivers. All buffers are now aligned with the cache + line size in both starting address and in length. This cause major + problems in unlucky builds where the USB host buffers where + unaligned and abutting other data. The cache flush and invalidate + operations could be subverted by accesses to adjacent data or could + have unexpected side effects. This bug has been in the ECHI drivers + forever, but was only revealed due to unlucky memory allocations + during the integration of the hub feature. + + * USB Device: + + - All USB device class drivers: There needs to be a check to make + sure that the size of a returned string does not exceed the size of + the allocated request buffer. Strings such as vendor names or + product names will be truncated to fit in the request buffer. + + * Networking: + + - TCP: Correct failures in long Telnet sessions by increasing th + size of the number of bytes sent from uint16_t to uint32_t. This + avoids an integer overflow that causes a long Telnet session to be + closed unexpectedly. From Rony XLN. + - Network locks: Correct some network lock logic: Two error + conditions where the network was not being unlocked and one where it + was getting unlocked twice. From Jussi Kivilinna. + - Local Sockets: Local stream sockets had problem of double releasing + pipes (both server and client attempt release), which causes wrong + pipe pair being closed in multi-client case. Solve by adding per + connection instance ID to pipe names. From Jussi Kivilinna. + - TCP: Fix an important TCP networking bug: 16-bit flags was being + converted to 8-bits in a few locations, causing loss of status + indications. + - TCP: net_startmonitor() always returned OK. In the race case + where a socket has already been closed, it correctly handled the + disconnection event but still returned OK. Returning OK caused the + callers of net_startmonitor() to assume that the connection was + okay, undoing the good things that net_startmonitor() did and + causing the socket to be incorrectly marked as connected. This + behavior was noted by Pelle Windestam. + - setsockopt() failed when setting timeouts to values less tha 100 + msec. That is because the timeout is limited to stops of 1 + decisecond and because the conversion of structure timeval was + truncating the microsecond remainder. The utility + net_timeval2dsec() now accepts and option to determine how it + handles the remainder: truncate, discarding the remainder, use + the remainder to round to the closed decisecond value, or use any + non-zero remainder to the next larger whole decisecond value. Bug + discovered by Librae. + - TCP: In the TCP connection operation, it was trying to setup the + network monitor BEFORE the socket was successfully connected. This, + of course, has ALWAYS failed because the socket is not yet connected + and the TCP state is not yet correct for a connected socket. However, + because of other changes net_startmonitor() now returns a failure + condition that causes worse problems when trying to connect. The fix + is to move the logic that starts the network monitor to AFTER the + socket has been successfully connected. + + * Atmel SAM3/4 Drivers: + + - SAM4CM and SAMA5D Free-running timer: Logic that samples the free + running counter reads the pending interrupt status register and can + cause interrupts to be lost. So, if when the status register is + read, the logic must also handle the timer overflow event. Found + and fixed by Max Neklyudov. + + * Atmel SAMA5 Drivers: + + - SAM3/4 Serial: When reconfigured, serial does not receive bytes + from UART. This happens because RX interrupt was disabled in the + setup routine. Fixed this I save interrupt configuration before + UART shutdown and restore it after. From Max Neklyudov. + + * NXP LPC17xx Drivers: + + - LPC176x GPIO: Reorder steps when an output GPIO is configured in + order to avoid transient bad values from being output. From Hal + Glenn. + - LPC17 USB OHCI: Correct some initialization of data structures. + When hub support is enabled, it would overwrite the end of an array + and clobber some OS data structures. + - LPC17xx Ethernet: Review, update, and modify the Ethernet driver so + that it works better with CONFIG_NET_NOINTS=y. Also, update all + LPC17xx networking configurations so that they have + CONFIG_NET_NOTINTS=y selected. + + * SiLabs EMF32 Drivers: + + - EFM32 SPI: Add missing SPI GPIO pin initialization. From Pierre-noel + Bouteville. + + * STMicro STM32: + + - STM32 F3: Added missing EXTI definitions for the STM32 F3; Correct + an error the port D base address in the STM32 F30x and F37x memory + maps. From Greg Meiste. + + * STMicro STM32 Drivers: + + - STM23 RTC: Fix an error introduced into stm32_pwr_enablebkp(). + That function must preserve the previous state of backup domain + access on return. + - STM32 RTC counter: Now need to enable backup domain write access + when setting the time. From Darcy Gong. + - STM32 OTG FS and HS: Added protection in the event that out-of-bound + endpoint numbers are received. From David Sidrane. + + * STMicro STM32 Boards: + + - STM32F429i Disco: (1) Fix a bad return value if the LCD driver is + already initialized. (2) The LCD driver initialization is now + performed during the early boot sequence. (3) Increased the size + of the message queue from 32 to 64 in the lcd configuration. From + Marco Krahl. + + * TI Tiva + + - Fixes for Tiva TM4C1294NCPDT. From Frank Sautter. + + * Atmel SAMV71 Drivers: + + - SAMV7 TWIHS: Fix SAMV TWIHS logic that performs multi-message + transfers with and without repeated starts. + + * Atmel SAMA5D3/4 Dirvers: + + - SAMA5 CAN: Fix SAMA5 CAN frame construction. From Max Holtzberg. + + * C Library/Header Files: + + - stdlib.h: MAX_RAND should be RAND_MAX. + - assert.h: Wrap definitions of assertion macros in do while so that + they are valid C statements. Numerous places throughout the code + where semicolons were missing at the end of an assertion also had to + be fixed. Suggested by orbitalfox. + - inetntoa(): Correct errors in printing IP address when type char is + signed and the value is >= 128. From Max Neklyudov. + + * Tools: + + - Tools: Fix test for the existence of the apps/ directory in + configure.c. Fix backward interpretation of options, -l was selecting + Windows and -w was selecting Linux. This was SourceForege Ticket #39. + + * Applications: apps/nshlib: + + - apps/nshlib/nsh_timcmds.c: Check return values from time functions. + - apps/nshlib/: Fix handling of gmtime_r return value in time commands. + gmtime_r returns a pointer, not an int. + + * Applications: apps/netutils: + + - apps/netutils/ntp: Fix mismatched sched_lock/unlock. Noted by Juha + Niskanen. + + * Applications: apps/examples: + + - apps/examples/nxlines: Fix missing right bracket that causes + compile error when CONFIG_NX_XYINPUT=y. From Librae. + - apps/examples: When boardctl() fails, need to print errno not the + returned value which will always be -1. + - apps/examples: Correct use of the BOARDIOC_GRAPHICS_SETUP boardctl() + call. + +NuttX-7.11 Release Notes +------------------------ + +The 111th release of NuttX, Version 7.11, was made on August 13 2015, +and is available for download from the Bitbucket.org website.

This moves + the DNS client logic from apps/ into the NuttX libc implementation. + + * Tools: + + - testbuild.sh: Add a script that can be used to perform building + testing for several board configurations. + + * Build/Configuration System: + + - apps/ Build System: No longer depends on hardcoded lists of + directories. Instead, it does a wildcard search to find all + appropriate directories. This means that to install a new + application, you simply have to copy the directory (or link it) into + the apps/ directory. If the new directory includes a Makefile and + Make.defs file, then it will automatically be included in the build. + - mkkonfig.sh: Add the tool mkkconfig.sh that dynamically builds the + apps/Kconfig file at configuration time. The hardcoded + configuration file has been removed and now the top-level Makefile + executes tools/mkkconfig.sh to auto-generate the top-level Kconfig + file. A new apps/ make target call preconfig: was added to support + this operation. Now you do not have to modify the top-level Kconfig + file to add a new directory into the configuration; the top-level + subdirectory simply needs to include a Kconfig file and it will + automatically be included in the configuration. The native Windows + build is temporarily broken until a new apps/tools/mkconfig.bat + script is generated. + - mkkconfig.bat: Add the Windows script corresponding to + apps/tools/mkkconfig.sh. Needed for a Windows native build. + + * Applications: apps/nshlib: + + - NSH shutdown command: NSH will now support an (optional) shutdown + command if the board provides the option CONFIG_BOARDCTL_POWEROFF. + The command can also be used to reset the system if + CONFIG_BOARDCTL_RESET=y. + - NSH uname command: Add support for a uname command. + - NSH nslookup command: Add an nslookup command. + + * Applications: apps/system: + + - NetDB: Add a system command to access the network database. + - readline(): Add support for Unix-style tab complete to readline. + Contributed by Nghia Ho. + - readline(): Extended the tab-completion support to also expand NSH + command names. + - readline(): Add support for an in-memory command line history that + can be retrieved using the up and down arrows. Contributed by Nghia + Ho. + + * Applications: apps/netutils: + + - DNS client: Moved the DNS client logic into the NuttX C library. + It is a necessary part for the full implementation of the netdb logic + and provides more flexibility in that location. + - Replace calls to the non-standard dns_gethotip() with calls to + standard gethostbyname(). + - NetLib: Create netlib wrapper functions around dns_getserver() and + dns_setserver() to isolate application code from changes to those + interfaces. + + * Applications: apps/examples: + + - OS test: Extend the OS test to include a test of + pthread_mutex_trylock() for recursive mutexes. From Juha Niskanen. + - OS test: Add a test for the sporadic scheduler. + +Bugfixes. Only the most critical bugfixes are listed here (see the +ChangeLog for the complete list of bugfixes and for additional, more +detailed bugfix information): + + * Core OS: + + - pthreads: Use -1 instead of 0 as PID for unclaimed mutexes. From + Juha Niskanen. + - pthreads: Implement pthread_mutex_trylock() for recursive mutexes. + From Juha Niskanen. + - pthread_create(): Group binding needs to be cleared before + sched_releasetcb(), as otherwise group_leave() will be called and + group->tg_nmembers decremented or group being released. group_leave() + should be called only after group_join() is called, not after + group_bind(). From Jussi Kivilinna. + - Protected Mode User Memory Allocator: Redesigned how the user space + heap is accessed from the kernel code in protected mode. It used to + call memory management functions in user space via function pointers + in the userspace interface. That is inefficient because the first + thing that those memory management functions do is to trap back into + the kernel to get the current PID. Worse, that operation can be + fatal is certain fragile situations such as when a task is exiting. + The solution is to remove all of the memory management function + calls from the interface. Instead, the interface exports the users + pace heap structure and then kernel size implementations of those + memory management functions will operate on the userspace heap + structure. This avoids the unnecessary system calls and, more + importantly, failures do to freeing memory when a test exits. + - pthread_create(): Fix an (unlikely) error in fallback value in the + event of a failure (which should never occur). + + * Common Drivers: + + - STMPE811 Driver: In stmpe811_instanciate() when + CONFIG_STMPE811_MULTIPLE is enabled, and the call to + stmpe811_checkid() fails, then the linked device list is not + restored to its previous state. From Sebastien Lorquet. + - CAN driver: Fix an issue in the CAN driver where the rx_sem count + can grow beyond bounds. + + * File System/Block Drivers: + + - NFS client: Fix prototype of unbind method. The function prototype + was not updated for NFS after a recent change to the file system + interface. From Manuel St??. + + * Networking/Network Drivers: + + - netconfig.h: Fix some backward compilation that was emitting #error + in the wrong condition when SLIP was enabled. + - SLIP Driver: Fix a missed name change when many of network + interface names changed sometime back but were apparently never + updated for SLIP. + - Networking: Allow receipt of empty UDP packets. From Max Neklyudov. + + * ARMv6-M: + + - ARMv6-M: Fix Cortex-M0 assembly error when the interrupt stack is + enabled. From Alan Carvalho de Assis. + + * Atmel SAMD/L Drivers: + + - SAMD20, D21, L21: In the SAML21, SERCOM5 uses a different SLOW clock + channel (and, hence, also a different SLOW GCLK generator). This + means that the channel selection cannot be a global definition but + must be a per SERCOM configuration setting. + - SAMD/L: Several fixes to register definitions and types. From + Janne Rosberg. + + * Atmel SAM3/4 Drivers: + + - SAM3/4 UART: Back out an error introduced with commit + 02c33f66c5a8be774034cd40e4125e9323c7b4d8. Causes an infinite loop in + up_lowputc(). From Max Neklyudov. + - SAM4CM: Fix SUPC register definitions. From Max Neklyudov. + - SAM3/4 WDT: Correct some problems with SAM3/4 watchdog driver. + Includes some small improvements. From Max Neklyudov. + + * Atmel SAMV7 Drivers: + + - SAMV7 UART: Also back the bad cloned change o sam_lowputc.c for + SAMV7 platform. + + * NXP LPC43xx Drivers: + + - LPC4350: Correct some LPC4350 GPIO pin configurations. From + Alessandro Temil. + + * SiLabs EMF32 Drivers: + + - EFM32 SPI: Correct write to incorrect register in EFM32 SPI driver. + From Pierre-noel Bouteville. + + * STMicro STM32 Drivers: + + - STM32 F15x: STM322 F15x stm32_stdclockconfig() was calling + stm32_pw_setvos() which accessed PWR_CR via an inactive APB From + Juha Niskaneni. + - STM32 Ethernet: Extend STM32 Ethernet operating frequency to 180MHz. + From Sebastien Lorquet. + + * STMicro STM32 Boards: + + - SAMV7 Xplained: In clock configuration, divider was set to 25 to get + 25*12MHz=300MHz CPU clock. The correct multiplier is 24 because the + calculation if (24+1)*12MHz. So the board was running at 312MHz. + From Efim Monjak. + + * ARMv7-A: + + - Cortex-A5 vfork(): Fix a Cortex-A compilation error when system + calls are enabled in modes other than CONFIG_BUILD_KERNEL. + + * Atmel SAMA5 Drivers: + + - SAMA5Dx EHCI: Fix some bad conditional compilation that left a + function undefined if CONFIG_USBHOST_ASYNCH is not selected. + + * C Library/Header Files: + + - getopt(): Uninitialized variable can cause hardfault from getopt() + if required argument is missing. From George McWilliams. + + * Applications: apps/nshlib: + + - NSH/THHPD: Change decoding to handle the increased size of the + scheduling policy field in the TCB. + + * Applications: apps/netutils: + + - THTTPD: Fix compilation problems when + CONFIG_THTTPD_GENERATE_INDICES is defined. + - THTTPD: Missing gci-src as a dependency path when building with + BINFS enabled. + + * Applications: apps/examples: + + - poll() example: Fix a few bit-rot compilation errors. + - Nx Lines example: If CONFIG_NX_ANTIALIASING=y, then the nxlines + example now erases a line that is 2 pixels longer and 2 pixels wider + than the line it drew. That eliminates edges effects due to + applying the anti-aliasing algorithm twice. A better solution + would be to make anti-aliasing an option for each graphics call so + you would rend the line with anti-aliasing ON and clear it with + anti-aliasing OFF. but I don't have the wherewithal for that change + today. + - OS test: Improve synchronization in round robin tests. On very fast + processors, there are race conditions that make the test fail. + Need better interlocking to assure that the threads actually do start + at the same time. + +NuttX-7.12 Release Notes +------------------------ + +The 112th release of NuttX, Version 7.12, was made on October 1, 2015, +and is available for download from the Bitbucket.org website. Note +that release consists of two tarballs: nuttx-7.12.tar.gz and +apps-7.12.tar.gz. These are available from: + + https://bitbucket.org/patacongo/nuttx/downloads + https://bitbucket.org/nuttx/apps/downloads + +Both may be needed (see the top-level nuttx/README.txt file for build +information). + +Additional new features and extended functionality: + + * Graphics/Graphic Drivers: + + - Added SSD1351 OLED controller support. Contributed by Paul + Alexander Patience. + + * Common Device Drivers: + + - MS58xx: Generalize the MS5805 altimeter driver to support other + family members. From Paul Alexander Patience. + - CAN driver interface: Add an error indication bit to the CAN + message report. + - Developed a new interface for QSPI. Most QSPI hardware (such as the + SAMV71) used a programmed interface to access the QuadSPI FLASH. + That programmed interface is no compatible with the simpler NuttX + SPI data transfer interface. + - Added a driver for ST25L1*K QuadSPI parts. + - Renamed the battery driver interface to battery_gauge since it + really only implements a battery fuel gauge. From Alan Carvalho de + Assis. + - Added a new framework to support a batter charger interface. From + Alan Carvalho de Assis. + - Added a BQ24250 battery charger driver. From Alan Carvalho de Assis. + + * Networking: + + - Added support for the local loopback device (dev lo, hostname localhost). + - Added NetDB support for the local loopback device. + - Network initialization: Automatically initialize all the TUN and + loopback devices if they arein the configuration. + + * Simulation Platform: + + - The simulation now runs under Cygwin64. Modern Cygwin X86_64 + machines follow the Microsoft ABI for parameter passing. The Linux + System 5 ABI would not work on X86_64-based Cygwin machines. Newer + Cygwin tool chains do nor pre-pend symbol names with the underscore + character. + + * Atmel SAMA5Dx: + + - Added architectural support for the Atmel SAMA5D2 parts. Not fully + verified in this NuttX release. + + * Atmel SAMA5Dx Boards: + + - Added support for the Atmel SAMA45D2 Xplained Ultra board. Not + fully verified in this NuttX release. + + * Atmel SAMV7 Drivers: + + - SAMV7 USBHS DCD: The device controller driver is (finally) + functional. + + * NXP LPC17xx: + + - Implement options to use external SDRAM and or SRAM for the heap. + From Pavel Pisa. + + * NXP LPC43x: + + - Added architectural support for the LPC4370. From Lok Tep. + + * NXP LPC43xx Drivers: + + - Added Ethernet support. From Ilya Averyanov. + - Added LPC43xx EHCI driver from Ilya Averyanov. + + * NXP LPC43xx Drivers: + + - Added support for the NXP LPC4370-Link2 development board from Lok + Tep. + + * STMicro STM32: + + - Added architectural for STM32F303K6, STM32F303K8, STM32F303C6, + STM32F303C8, STM32F303RD, and STM32F303RE devices. From Paul + Alexander Patience. + + * STMicro STM32 Drivers: + + - Added OTG support for STM32F44x. From David Sidrane. + + * STMicro STM32 Boards: + + - Added support for the STMicro Nucleo F303ERE board from Paul + Alexander Patience. + + * C Library/Header Files: + + - stdlib: Add support for div() to the C library. From OrbitalFox. + Also added ldiv() and lldiv() which are equivalent to div() with + long and long long types, respectively, instead of int. + - Added an implementation of the standard shutdown function. + + * Tools: + + - tools/mksymtab: declare g_symtab array as const to occupy RO section + (Flash). From Pavel Pisa. + + * Build/Configuration System: + + - Simplify configs/ Makefiles by combining common logic into a new + Board.mk Makefile fragment. From Paul Alexander Patience. + + * Applications: apps/system: + + - apps/system/symtab: Optional canned symtab inclusion to the build. + When option CONFIG_SYSTEM_SYMTAB is selected and symbol table file + libc/symtab/canned_symtab.inc is prepared then application can use + system provided complete symbol table. The option has substantial + effect on system image size. Mainly code/text. If loading of + applications at runtime is not planned do not select this. From + Pavel Pisa. + + * Applications: apps/canutils: + + - apps/canutils/uavcan: Add support for libuavcan. From Paul Alexander Patience. + + * Applications: apps/examples: + + - apps/examples/can: Extend the CAN loopback test by adding more + command line options. + - apps/examples/usbserial: Can now be run as an NSH builtin-function. + Now uses a configurable IO buffer size. + - apps/examples/nettest: Add option to suppress network initialization. + This is necessary if the nettest is run from NSH which has already + initialized the network. + - apps/examples/nettest: Extend test so that can be performed using + the local loopback device. + - apps/examples/netloop: Add a test of the local loopback device. + - apps/examples/udpblaster: Add a test to stress the network by + sending UDP packets at a very high rate. . + - apps/examples/uavcan: libuavcan example from Paul Alexander Patience. + +Bugfixes. Only the most critical bugfixes are listed here (see the +ChangeLog for the complete list of bugfixes and for additional, more +detailed bugfix information): + + * Core OS: + + - wd_create(): Correct a counting error in the number of available + watchdog timers. When the number of free timers is low, the counter + could be incremented below zero. + - mq_open(): When message queue is opened, inode_reserve() leaves the + reference count at zero. mq_open() logic must assure that the + reference count of the newly created inode is one. + - work_queue(): Logic that sets the queued indication and the logic + that does the actual queuing must be atomic. + + * Binary Loader: + + - Fix a memory leak in the built-in application logic: File was not + being closed. From Bruno Herrera. + + * File System/Block Drivers: + + - poll(): If we fail to setup the poll for any file descriptor, for + any reason, set the POLLERR bit. + - rwbuffer: Fix some logic errors. From Dmitry Nikolaev via Juha + Niskanen. + - ROMFS: One allocation was not being freed if there was a subsequent + failure to allocation I/O buffers resulting in a memory leak on + certain error conditions. From Bruno Herrera. + + * Networking/Network Drivers: + + - Fix a bug in tun interface driver. From Max Neklyudov. + - recvfrom(): Correct wait for new data when NET_UDP_READAHEAD is + enabled. Fix size accounting when recvfrom_udpreadahead() sets + state.rf_recvlen == -1. I have not checked if data are accumulated + to the right position in the buffer however. From Pavel Pisa. + - networking: Correct return value from psock_tcp_accept(). From + SaeHie Park. + - TCP: Fix a problem in when there are multiple network devices. + Polls were being sent to all TCP sockets before. This is not good + because it means that packets may sometimes be sent out on the wrong + device. That is inefficient because it will cause retransmissions + and bad performance. But, worse, when one of the devices is not + Ethernet, it will have a different MSS and, as a result, incorrect + data transfers can cause crashes. The fix is to lock into a single + device once the MSS is locked locked down. + - net/tcp: The logic that binds a specific network device to a + connection was faulty for the case of multiple network devices. On + bind(), the local address should be used to associate a device with + the connection (if the local address is not INADDR_ANY); On connect(), + the remote address should be used (in case the local address is + INADDR_ANY). On accept(), it does not matter but the remote address + is the one guaranteed to be available. + - net/tcp: Fix unbuffered send compilation error when Ethernet is not + enabled. From Alan Cavalho de Assis. + + * ARMv7-M: + + - All ARMV7-M IRQ setup: Always set the NVIC vector table address + unconditionally. This is needed in cases where the code is running + with a bootload and when the code is running from RAM. It is also + needed by the logic of up_ramvec_initialize() which gets the vector + base address from the NVIC. Suggested by Pavel Pisa. + - Fix some H/W floating point logic: In the original implementation, + !defined(CONFIG_ARMV7M_CMNVECTOR) was a sufficient test to determine + if lazy floating point register saving was being used. But recents + changes added common lazy register as well so now that test must be + (!defined(CONFIG_ARMV7M_CMNVECTOR) || defined(CONFIG_ARMV7M_LAZYFPU)). + - ARMv7-M, all "lazy" interrupt stack logic. Assembly instruction + that fetches the saved value is incorrect; replace with more + traditional push and pop. This is an important fix. Noted by + Stefan Kolb. + - All ARMV7-M: Force 8-byte stack alignment when calling from assembly + to C to interrupt handling. + - up_schedulesigaction(): Fix logic that determines if there is a + pending signal action before scheduling the next signal action. + Both the test and the scheduling action need to be atomic. This + problem was fixed on the ARMv7-M but also ported to other + architectures that had the same issue. + + * NXP LPC43xx: + + - LPC43xx: Fix NVIC_SYSH_PRIORITY_STEP define. From Ilya Averyanov. + - LPC43xx: Fix missing #define in eeprom. From Ilya Averyanov. + + * NXP LPC43xx Drivers: + + - Fixed the SPI driver. From Ilya Averyanov. + + * Atmel SAMA5 Drivers: + + - LPC31 and SAMA5D EHCI: Fix qh_ioccheck to move bp to next QH. From + Ilya Averyanov. + - LPC31 and SAMA5D EHCI: Performance improvement: Do not disable the + asynchronous queue when adding a new QH structure. From Ilya + Averyanov. + + * C Library/Header Files: + + - gethostbyname(): correct returned address format when DNS is used. + The hostent.h_addr_list should point to raw in_addr or in6_addr + as defined in the standard. Original implementation used that for + numeric addresses but for DNS lookup returned pointer to whole + sockaddr_in or sockaddr_in6. From Pavel Pisa . + - asin(): The function did not convert for some input values. asing() + did not convert for values which do not belong to the domain of the + function. But aside of that the function also did not converge for + allowed values. I achieved a conversion of the function by + reducing the DBL_EPSION and by checking if the input value is in + the domain of the function. This is a fix for the problem but the + function should always terminate after a given number of iterations. + From Stefan Kolb. + - Change all references from avsprintf to vasprintf. From Sebastien + Lorquet. + + * Applications: apps/nshlib: + + - Fix error handling in 'cat' command. On a failure to allocate + memory, a file was not being closed. From Bruno Herrera. + - Fix error handling in 'mv' command. On a failure to expand the + second path, the memory allocated for the expansion of the first + path was not being freed. From Bruno Herrera. + + * Applications: apps/system: + + - apps/system/netdb: Failed to build if CONFIG_NET_HOSTFILE was not + defined because gethostbyaddr() was not available. Noted by + OrbitalFox. + + * Applications: apps/netutils: + + - Various Kconfig files in netutils: Fix some changes from from + NETUTILS_DNSCLIENT to NETDB_DNSCLIENT. From Pavel Pisa. + + * Applications: apps/modbus: + + - Macros PR_BEGIN_EXTERN_C and PR_END_EXTERN_C were not defined in + all contexts. Replace with explicit expansion in all cases. From Stefan Kolb. + +NuttX-7.13 Release Notes +------------------------ + +The 113th release of NuttX, Version 7.13, was made on December 5, 2015, +and is available for download from the Bitbucket.org website. Note +that release consists of two tarballs: nuttx-7.13.tar.gz and +apps-7.13.tar.gz. These are available from: + + https://bitbucket.org/patacongo/nuttx/downloads + https://bitbucket.org/nuttx/apps/downloads + +Both may be needed (see the top-level nuttx/README.txt file for build +information). + +Additional new features and extended functionality: + + * Core OS: + + - External RTC: Added OS support for external RTC chips. + - boardctl(): Add a command to the boardctl() interface to obtain a + board unique ID. + + * File Systems: + + - TMPFS: Add support for a new TMPFS, RAM file system. The TMPFS + file system does not require any significant amount of memory + itself. It will grow dynamically as files are added and shrink back + when files are deleted. A very low overhead way to retain temporary + files. + - VFS: The VFS was extended to support standard file operations on + block drivers (open, close, read, write, etc.). The open() interface + accomplishes this by creating a temporary characer driver to mediate + the character oriented accesses to tje block driver. + - HOSTFS: Added a HOSTFS file system for use with the simulator. The + HOSTFS file system mounts in the simulated Nuttx context by provides + proxied access to the file system on the host PC. This is useful for + providing file system content and nonvolatile storage of files in the + simulation environment. From Ken Pettit. + - MTD/PROCFS: Add an interface to un-register an MTD procfs entry. + From Ken Pettit. + - filemtd: A new MTD conversion layer that will convert a regular file + (or driver file) to an MTD device. This is useful for testing on the + simulation using the HOSTFS. From Ken Pettit. + - PROCFS: Extended to include networking entries in the procfs. Device + status, device statistics, and network statistics are now available + from the PROCFS. + - PROCFS: The PROCFS file system can now be configured so that it + supports runtime registration of PROCFS entries with + CONFIG_FS_PROCFS_REGISTER=y. + + * Graphics/Graphic Drivers: + + - ST7565 Driver: Extend to include support for the ERC12864-3. From + Pierre-noel Bouteville. + + * Common Device Drivers: + + - User buttons: Added a character driver to support application access + to board buttons. Supports notification of button activity via + signals. + - User LEDs: Added a character driver to support application access + to on-board LEDs. + - Zero Cross: Added a Zero Cross device driver support. From Alan + Carvalho de Assis. + - MAX6675: Added support to Thermocouple-to-Digital converter MAX6675. + From Alan Carvalho de Assis. + - BCH: Block-to-character (BCH) driver should forward ioctl() calls + to the contained block driver. + - S25FL1xx: Added a S25FL1xx QuadSPI FLASH driver. + - On-Chip FLASH: Added an upper half MTD device that can use the + interfaces defined in included/nuttx/progmem.h to provide a + standard MTD driver. + - Serial: Implemented high level DMA infrastructure for serial + devices. From Max Neklyudov. + - AT24XX: Add support for multiple AT24xx EEPROM parts, each with + unique I2C addresses, but otherwise identical. + - External RTC: Added drivers for external I2C RTC chips: DS3102, + DS1307, DS3231, DS3232, and NXP PCF85263. + - W25: Added support for byte write mode to the W25 FLASH driver. From + Ken Pettit. + - dev/loop: Added a loop character device. losetup() and loteardown() + should not be called directory from applications. Rather, these + functions are now available as IOCTL commands to the loop driver. + - dev/smart: Added support for a /dev/smart loop device. From Ken + Pettit. + + * Networking: + + - Driver Statistics: Most network drivers do not support statistics. + Those that do only supported them when DEBUG is enabled. Each + driver collected an architecture specific set of statistics and + there was no common mechanism to view those statistics. Thus, + the driver feature was mostly useless. This release standardizes + the driver statistics and puts the definition in the common network + device structure defined in netdev.h where they can be accessed by + network applications. All Ethernet drivers that collect statistics + have been adapted to use these common statistics. + + * Simulation Platform: + + - W25 FLASH: Added support for W25 FLASH simulation. From Ken Pettit. + - HOSTFS: Added support for the HOSTFS file system (see "File Systems", + above). + + * Atmel SAMV7: + + - SAME70: Added support for the SAME70 family of chips. + - Tickless: SAMV7 now supports the tickless mode of operation. + + * Atmel SAMV7 Drivers: + + - MPU: Added MPU and protected build support. + - QSPI: Added a QuadSPI FLASH driver. This driver operates in the + memory-mapped, Serial Memory Mode (SMM). + - FLASH: Added support to write on-chip FLASH. + - Timer/Counter: TC driver ported to SAMV7 from the SAMA5. Free-running + and one-short timer logic also ported. + - PCK: Brought programmable clock (PCK) logic from SAMA5 into SAMV7. + - Timer/Counter: Support PCK6 as an optional source for the timer/ + counter clock. + + * Atmel SAMV7 Boards: + + - SAME70-Xplained: Add NSH and networking configurations for the + SAME70 Xplained board. Includes verified support for serial console, + LEDs, buttons, SDRAM, HSMCI SD card, and networking. + - SAMV7-XULT and SAME70-Xplained: If Tickless mode is selected then + enable PCK6 as a timer/counter clock source + + * STMicro STM32: + + - CCM PROCFS: Is no longer a part of the 'base' procfs entries and can + now only be supported via run time registration with + CONFIG_FS_PROCFS_REGISTER=y. + + * STMicro STM32 Drivers: + + - Timers: Add a compatible lower-half timer driver for use with the + common timer upper-half driver. From Wail Khemir. + + * STMicro STM32 Boards: + + - STM32F4-Discovery: Add low level support for the Zero Cross driver + for the STM32F4-Discovery. From Alan Carvalho de Assis. + - STM32F4-Discovery: Add board config to support for the MAX6675. From + Alan Carvalho de Assis. + + * C Library/Header Files: + + - bsearch(): Added the bsearch() function from NetBSD. + - freopen(): Added support for freopen(). + - strftime(): Added day-of-week support (when avaialable). + + * Tools: + + - nxstyle: Add crappy style checking tool nxstyle.c. See thee tools/ + README file for more info. + + * Applications: NSH + + - mksmartfs command: Add configuration option to supported multiple + rootdirectories. From Ken Pettit. + - Add support for 'basename' and 'dirname' commands. + - set command: Like bash, NSH set command now strips off any leading + or trailing whitespace. + - mount command: The mount commands now accepts mount options + (currently needed only for the hostfs file system). From Ken + Pettit. + - losetup command: NSH no longer calls losetup() and loteardown + directly. Now it opens /dev/loop and accomplishes these things + using ioctl() calls. + - ifconfig command: If CONFIG_NETDEV_STATISTICS=y, then print the + network driver statistics in the ifconfig. + - ifconfig, ifup, and ifdown: These commands now uses /proc/net/ + to view network device configuration and status and /proc/net/stat + to show network statistics. A consequence of this is that you + cannot view this network information if the procfs is not enabled + and mounted at /proc. + - losmart command: Added a new NSH losmart command. losmart setups + up a loop device for the smart MTD driver similar to losetup but + with different syntax. From Ken Pettit. + - ps command: The 'ps' command now uses /proc// to obtain task + status information. A consequence of this is that you cannot use + the 'ps' command if the procfs is not enabled and mounted at /proc. + + * Applications: apps/system: + + - apps/system/hexed: Port the hexed command line hexadeciamal editor + to Nuttx. See http://apps.venomdev.net/hexed/. + + * Applications: apps/fsutils: + + - apps/fsutils/smartfs: Move into apps/fsutils from kernel, now uses + only open and ioctl. From Ken Pettit. + + * Applications: apps/examples: + + - apps/examples/fstest: Add a generic file system test. This is + essentially the same as examples/smart, but has all of the SmartFS + specific logic ripped out. This was created for testing the new + TMPFS. + - apps/examples/zerocross: Add a Zero Cross application example. From + Alan Carvalho de Assis. + - apps/examples/media: Add a simple test for access of media via a + block driver or MTD driver. + +Bugfixes. Only the most critical bugfixes are listed here (see the +ChangeLog for the complete list of bugfixes and for additional, more +detailed bugfix information): + + * Core OS: + + - Fixed an error in clock_timespec_subtract(). Found by Lok. + - pthreads: CRITICAL BUGFIX: Logic was wiping out the indication that + of the type of a pthread. Hence, it could be confused as a task. + Found because this was causing a crash when /proc/nnn/cmdline was + printed. + + * File System/Block Drivers: + + - SMART MTD: Fix some Smart wear-leveling bugs. Fixed SmartFS wear + level error that occurs when the logical sector size is too small to + save all wear level status bytes in a single sector. Logical + sectors 1 and 2 were simply not being allocated and then the + read_sector and write_sector routines were failing. From Ken + Pettit. + + * Graphics/Graphic Drivers: + + - ILI9432: Fixed errors in orientation. Portrait, RPortrait, and + Landscript should work correly now. They were displayed mirrored. + From Marco Krahl. + + * Common Drivers: + + - CAN: Fix a problem in the CAN upper-half driver that occurs only + for CAN hardware that support a H/W FIFO of outgoing CAN messages. + In this case, there can be a hang condition if both the H/W and + S/W FIFOs are both full. In that case, there may be no event to + awaken the upper half driver. Add a new (conditional) CAN upper + half interface called can_txready() that can be used by the lower + half driver to avoid this hang condition. + - MS58xx: Fix some issues with initialization and with CRC + calculation. From Karim Keddam. + - W25: Fixed W25 FLASH driver page read/write logic. From Ken Pettit. + + * Atmel SAMV7 Drivers: + + - USART1 pin configuration: Reconfigure System I/O when using USART1. + From Frank Benkert. + - MCAN: Added a call to can_txready() to the MCAN driver. + + * STMicro STM32 Drivers: + + - stm32 F4: Fix some TIM12 pin mappings. From Max Kriegleder. + + * STMicro STM32 Boards: + + - STM32F429i-Disco: Calculated partition boundries based on page + block sizes but mtd_partition() is expecting calculations based on + erase block size. From Alan Carvalho de Assis. + + * C Library/Header Files: + + - sys/types.h: When building on a 64-bit machine, the size of size_t + should be 64-bits. In general, I believe that sizeof(size_t) should + be the same as sizeof(uinptr_t). mmsize_t should always be 32-bits + in any event. The last change to stddef has been backed out. With + these changes, the simulator builds without errors or warnings an a + 64-bit machine. + + * Applications: apps/nshlib: + + - The I/O buffer, g_iobuffer, should not be a global buffer. That + will not work in an environment where there are multiple NSH + sessions. The I/O buffer must, instead, be a part part of the + session-specific data defined in nsh_console.h. + +NuttX-7.14 Release Notes +------------------------ + +The 114th release of NuttX, Version 7.14, was made on January 28, 2016, +and is available for download from the Bitbucket.org website. Note +that release consists of two tarballs: nuttx-7.14.tar.gz and +apps-7.14.tar.gz. These are available from: + + https://bitbucket.org/patacongo/nuttx/downloads + https://bitbucket.org/nuttx/apps/downloads + +Both may be needed (see the top-level nuttx/README.txt file for build +information). + +Additional new features and extended functionality: + + * Core OS: + + - modules: Add support for kernel modules: insmod, rmmod, support + functions. procfs support for user lsmod functioniality. + - SIGEV_THREAD: Add support for the SIGEV_THREAD notification method + in struct sigevent. This initial implementation will only work in + the FLAT build since it utilizes the work queue for signal + callbacks. See the top-level TODO file for additional details. + - 64-Bit Timer: If the 64-bit timer is selected, then use it whenever + clock_systimer() is called rather then chopping the 64-bit timer + down to 32-bits. Add a new type, systime_t to represent the 32- or + 64-bit system timer. This eliminates clock_systimer32() and + clock_systime64(); there is now only clock_systimer(). + + * Common Device Drivers: + + - Telnet Driver: Move the Telnet driver from apps/ to + nuttx/drivers/net. It is a driver a belongs in the OS. Now works + like the loop device: A new interface called telnet_initialize() + registers a telnet session "factory" device at /dev/telnet. Via + ioctl, the factory device can create instances of the telnet + character devices at /dev/telnetN to support Telnet sessions. + - PCA9635PW: Add a driver for the PCA9635PW I2C LED driver IC which + can be used to control the intensity of up to 16 LEDs. From + Alexander Entinger. + - MCP9844: Driver for the MCP9844 I2C digital temperature sensor with + a selectable resolution. From Alexander Entinger. + - PN532: Add driver for the NXP PN532 NFC-chip. From Janne Rosberg + and others at Offcode Ltd. + - LSM9DS1: Add driver for the STMicro LSM9DS1 chip. The LSM9DS1 is a + system-in-package featuring a 3D digital linear acceleration sensor, + a 3D digital angular rate sensor, and a 3D digital magnetic sensor. + From Paul Alexander Patience. + - CAN Interface: Add more extensive error reporting capaibility to + the CAN interface definitions. From Frank Benkert. + - SPI Interface: Add an optional hwfeatures() method to the SPI + interface. + + * Simulation Platform: + + - NSH configuration uses the custom start up scriptwith a read-only + passwd file. Includes hooks for an MOTD message. + + * ARMv7-R + + - ARMv7-R: Add basic architecture support for the ARMv7-R processor + family. + + * Atmel AVR: + + - Atmega2560: Add support for the Atmega2560. From Dimitry Kloper. + - debug.h: Add an AVR-specific header file used when the AVR MEMX + pointer is used. From Dimitri Kloper. + + * Atmel AVR Boards: + + - Arduino-Mega2560: Add support for the Arduino-Mega2560. From + Dimitry Koper. + + * Atmel SAMV7 Drivers: + + - Port the TRNG driver from the SAMA5D3/4 to the SAMV7. + - Port the WDT driver from the SAMA5D3/4 to the SAMV7. + - Add an RSWDT driver. + + * Atmel SAMV7 Boards: + + - SAMV71-XULT: Add configuration for testing OS modules. + + * Freescale Kinetis: + + - MK60N512VLL100: Add support for the MK60N512VLL100 Kinetis part. + From Andrew Webster. + + * Freescale Kinetis Boards: + + - ENET: Numerous updates to the Kinetis ENET driver. That driver is + now functional. From Andrew Webster. + + * NXP LPC43xx Boards: + + - WaveShare LPC4337-WS: Support for the WaveShare LPC4337-WS board. + From Lok Tep. + + * STMicro STM32 Drivers: + + - Timer Capture: Add timer input capture driver. From Pierre-Noel + Bouteville. + + * STMicro STM32 Boards: + + - Olimex STM32 H407: Added a port to the Olimex STM32 H407 board. + This board features the STMicro STM32F407ZGT6 (144 pins). + Contributed by Neil Hancock. + + * TI TMS550 Boards: + + - TI LaunchXL-TMS57004: Add basic board support for TI LaunchXL- + TMS57004. Still a work in progress. + + * C Library/Header Files: + + - sys/time.h: Add timeradd(), timersub(), timerclear(), timerisset(), + and timercmp() as macros. These are non-POSIX interfaces, but + included in most BSD deriviatives, including Linux. From Manuel St??. + - AVR support: Introduce support for Atmel toolchain in-flash strings. + Atmel toolchain AVR compiler provides a transparent in-flash object + support using __flash and __memx symbols. The former indicates to + compiler that this is a flash-based object. The later used with + pointer indicates that the referenced object may reside either in + flash or in RAM. The compiler automatically makes 32-bit pointer + with flag indicating whether referenced object is in flash or RAM + and generates code to access either in run-time. Thus, any function + hat accepts __memx object can transparently work with RAM and flash + objects. + For platforms with a Harvard architecture and a very small RAM like + AVR this allows to move all constant strings used in trace messages + to flash in the instruction address space, releasing resources for + other things. This change introduces IOBJ and IPTR type qualifiers. + The 'I' indicates that the object may lie in instruction space on a + Harvard architecture machine. For platforms that do not have __flash + and __memx or similar symbols IOBJ and IPTR are empty, making the + types equivalent to, for example, 'const char' and 'const char*'. + For Atmel compiler these will become 'const __flash char' and + 'const __memx char*'. All printf() functions and syslog() functions + are changed so that the qualifier is used with the format parameter. + From Dimitry Kloper. + - debug.h: Add configuration to support an architecture-specific + debug.h header file. From Dimitri Kloper. + - netdb: Add support for the use of a DNS resolver file like + /etc/resolv.conf. + - TEA: Add an implementation of the Tiny Encryption Algorithm. + - math32.h: Add some utilities to support 64-bit arithmetic + operations for platforms that do not support long long types. + + * Tools: + + - tools/cnvwindeps.c: Add a tool that will convert paths in + dependencies generated by a Windows compiler so that they can be + used with the Cygwin make. + - tools/mkwindeps.sh: A script that coordinates use of cnvwindeps.exe. + Dependencies now work on the Cygwin platform when using a Windows + ative toolchain. + + * Applications: NSH + + - Module Commands: Add module commands: insmod, rmmod, and lsmod. + - Time Command: Add a 'time' command that may be used to time the + execution of other commands. + - Password Commands: Add useradd, userdel, and passwd commands. + - MOTD: Now supports a Message of the Day (MOTD) that will be + presented after the NSH greeting. + - Session Logins: All sessions may be protected with logins using the + encrypted password in /etc/passwd. + - Extended Logins. Added optional platform-specific function to + perform password verification and optional delay after each failed + login attempt. + + * Applications: apps/fsutils: + + - apps/fsutils/passwd: Utility library for accessing a password file + like /etc/passwd. + + * Applications: apps/netutils: + + - apps/netutils/telnetd: Now creates Telnet sessions by opening a new + factory device at /dev/telnet and then using ioctl calls to create + the session character drivers at /dev/telnetN. + - apps/netutils/netlib: Add netlib_get_dripv4addr() and + netlib_get_ipv4netmask(). From Pelle Windestam. + + * Applications: apps/examples: + + - apps/examples/module: Add a test harness for verifying NuttX kernel + modules. + - apps/examples/pca9635: Add a simple test of PCA9635PW PWM LED driver. + From Alan Carvalho de Assis. + - apps/examples/ostest: Add a test of POSIX timers using SIGEV_THREAD. + +Bugfixes. Only the most critical bugfixes are listed here (see the +ChangeLog for the complete list of bugfixes and for additional, more +detailed bugfix information): + + * Core OS: + + - pthreads: CRITICAL BUGFIX: Logic was wiping out the indication that + of the type of a pthread. Hence, it could be confused as a task. + - waitpid: CRITICAL BUGFIX. Add a reference count to prevent waitpid + from using stale memory released by the waited-for task group. + - clock_systimespec(): Fix an error in a time conversion. + + * File System/Block Drivers: + + - poll(): Fix handling of sem_tickwait() return value sem_tickwait() + does not return an -1+errno, it returns a negated errno value. + Noted by Freddie Chopin. + + * Common Drivers: + + - TUN Driver: Fix a compile time error in the TUN driver. From + Vladimir Komendantskiy. + - USB Host HID Parser: Wrong size used in memcpy(). From Hang Xu. + - PCA9555: Fixed a bug in the function pca9555_setbit which occurs if + someone tries to set one of the pins 8-15. The problem is that + after the check if the pin is greater than 7 the variable addr is + incremented and used in the Call I2C_WRITEREAD. But later in the + call to the I2C_WRITE buf[0] is used as address but this address is + not incremented as it should be. Note address does mean the address + to the register in the ioexpander and not the I2C address. From + Stefan Kolb. + + * Networking: + + - TCP/IOB: Numerous fixes, mostly relate to TCP and IOB buffering + and race conditions. These were necessary for for the NuttX + networking later to be stable in some stress testing. From Andrew + Webster. + + * Atmel SAMV7 Drivers: + + - USBHS Device: In USBHS device driver, fix check if zero length + packet is needed. + + * STMicro STM32 Drivers: + + - OTG FS Host: Fix some backward arguments to stm32_putreg(). Note + by Hang Xu. + + * Tools: + + - tools/mkdeps.c: Extended/fixed support for --winpath option. + Dependencies now work under Cygwin with a native Windows toolchain. + + * Build System: + + - apps/platform/Makefile: Use a relative path to the board directory + link rather than the absolute path. For Cygwin, the absolute would + would need converted with cygpath. But just using the relative path + is a simpler solution. + +NuttX-7.15 Release Notes +------------------------ + +The 115th release of NuttX, Version 7.15, was made on March 27, 2016, +and is available for download from the Bitbucket.org website. Note +that release consists of two tarballs: nuttx-7.15.tar.gz and +apps-7.15.tar.gz. These are available from: + + https://bitbucket.org/patacongo/nuttx/downloads + https://bitbucket.org/nuttx/apps/downloads + +Both may be needed (see the top-level nuttx/README.txt file for build +information). + +Additional new features and extended functionality: + + * Core OS: + + - Add a state variable that provides the current level of OS + initialization. This is needed by some logic that may attempt to + run early in the start-up sequence but cannot run if a sufficient + level of initialization has not yet occurred. + - Spinlocks: Add interface definitions for to support spinlocks as + needed for multi-CPU configurations. + - SMP support. Support for Symmetric Multi-Processing (SMP) added. + This affects many internal data structures, spinlock extensions + and renaming of interrupt enable/disable interfaces, new platform + interfaces to support CPU initialization and inter-actions, and + new application interfaces to manage CPU affinity. The changes + are too extensive to summarize here; see the SMP Wiki page at + http://www.nuttx.org/doku.php?id=wiki:nxinternal:smp. The + new platform interfaces are also described in the NuttX porting + guide: http://www.nuttx.org/doku.php?id=documentation:portingguide. + Only partially verified; awaiting hardware for the complete + verification. + - TLS: Basic definitions needed to support thread local storage + (TLS). TLS is not used anywhere yet (and may not be used in the + near future either). + - Performance Monitoring: Add a configuration option to buffer + RTOS instrumentation data in an in-memory buffer. + - boardctl(): Add boardctl() support that will permit applications + to control USB devices. + + * File Systems/Block Drivers: + + - procfs: Add /proc/kmm entry that shows that state of the kernel + heap. Only useful in PROTECTED and KERNEL build modes where there + is a kernel heap. + - procfs: Add support for showing CPU in the tast status if SMP is + enabled. + + * Networking: + + - ARP: Add support for IOCTL commands to manage the ARP table. + - IEEE 802.15.4 and 6LowPAN: There are some radio drivers and a + directory structure is in place. However, most of this + development is occurring on a fork and is not yet available in the + NuttX repositories. Hopefully in NuttX-7.16. + + * Common Device Drivers: + + - ADS1242: Driver for the 24-Bit Differential Input ADC ADS1242 that + communicates via SPI with a MCU. Reading the ADC conversion result + as well as configuring the ADC, setting the input channel, etc. is + implemented via ioctl calls. However, it does not yet implement + the standard ADC interface. From Alexander Entinger. + - U-Blox Modem: Add an upper half driver for the U-Blox Modem. From + Vladimir Komendantskiy. + - I2C: Add an I2C, "upper half", character drivers to support raw I2C + data transfers for test applications. + - RGB LED: Add a driver to manage a RGB LED via PWM. From Alan + Carvalho de Assis. + - Performance Monitoring: Add a character driver that will allow an + application to read buffered scheduler instrumentation data. + + * Simulation Platform: + + - SMP: Add multi-CPU support to the simulation to support SMP + investigation. There are issues with the simulation and it is less + than perfect but sufficient for some very preliminary testing of + the core SMP feature. + + * ARMv7-A, ARMv7-R, and ARMv7-M: + + - ARMv7-A, ARMv7-R, and ARMv7-M: Add test-and-set logic and + definitions needed to supports spinlocks. + - ARMv7-A: Added MPCOre Generic Interrupt Controller (GICv2) and + Global Timer support + - ARMv7-A: Now includes in MCU-specific hooks needed for SMP support. + + * Atmel SAMV7 Drivers: + + - HSMSI: HSMCI driver can now be configured to handle unaligned data + buffers. + + * NXP Freescale LPC11xx/17xx/43xx and LPC2378 Drivers: + + - I2C: Backported the LPC43XX I2C driver, replacing the LPC11XX, + LPC17XX, and LPC2378 I2C drivers. This gives us the I2C_TRANSFER + method in all I2C drivers. + + * NXP Freescale LPC17xx Boards: + + - Support for the u-blox GSM and GPS module evaluation board with + NXP LPCExpresso LPC1768. The GSM module is one of LISA-C200, + LISA-U200 or SARA-G350. The GPS module is one of MAX-M7 or + MAX-M8. From Vladimir Komendantskiy. + + * NXP Freescale i.MX6: + + - Basic support is in place for the i.MX6 Quad/Dual MCUs. + Verification is, however, waiting for the receipt of hardware. + + * NXP Freescale i.MX6 Boards: + + - Sabre-6Quad: Basic support for the NXP/Freescale Sabre 6Quad + board is in place but waiting for hardware for verification. + + * STMicro STM32: + + - STM32F46xx: Support for STM32F46xx from Paul Alexander Patience + - STM32L4: Add support for the STM32L4 family. From Sebastien + Lorquet. + + * STMicro STM32 Boards: + + - STM32F4 Discovery: Add PWM support for the onboard RGB LED. From + Alan Carvalho de Assis. + - Nucleo-L476: Add support for the Nucleo-L476 board. From Sebastien + Lorquet. + - STM32L476VG Discovery: Add support for the STM32L476VG Discovery + board. From Dave. + + * Tools: + + - tools/refesh.sh now has a --silent option so that it can be used in + batch modes without human input. + + * Build System: + + - Added a 'make olddefconfig' target that will refresh a .config file + without interaction. + + * Applications: NSH + + - 'arp': Add an 'arp' command that will support access to the OS ARP + table. + - 'ps': The 'ps' command will show CPU if SMP is enabled. + + * Applications: apps/netutils: + + - apps/netutils/chat: Chat logic contributed by Vladimir + Komendantskiy. + - apps/netutils/netlib: Add utility functions to support accesses to + the ARP table. + + * Applications: apps/examples: + + - apps/examples/chat: Chat example contributed by Vladimir + Komendantskiy. + - apps/sysem/ubloxmodem: Example to control the power + state of the modem in nsh. From Vladimir Komendantskiy. + - apps/examples/leds: An example to demonstrate use of LED driver. + - apps/examples/smp: Add a test to verify SMP configurations. + - apps/examples/rgbled: Example using the RGB LED driver to drive an + RGB LED via PWM. From Alan Carvalho de Assis. + - apps/examples/ostest: Add a test of TLS. + - apps/examples/sched_note: Add a simple example to exercise the + scheduler instrumentation logic. + +Bugfixes. Only the most critical bugfixes are listed here (see the +ChangeLog for the complete list of bugfixes and for additional, more +detailed bugfix information): + + * Core OS: + + - Signals: Move the list of signal actions from the TCB to the group + structure. Signal handlers are not per thread but, rather, per task + group. I know, I preferred it the other way too, but this is more + compliant with POSIX. + - Semaphores: Add an internal, non-standard interface to reset a + semaphore count. This is sometimes needed by drivers in order to + recover from error conditions. Were previously using sem_init() + which is both inappropriate and incorrect if the semaphore count is + negative. + - Low-Priority Work Queue: Fix logic to find an IDLE worker thread; + the test for busy was backward. From Linfei Chen. + + * File System/Block Drivers: + + - FAT: Add an option to force all transfers to be performed + indirectly using the FAT file system's internal sector buffers. + This is a fix for the case where the user provided buffers are not + properly aligned for DMA (as with THTTPD). + - MTD: Increase block size in mtd_geometry_s to 32-bits. + + * Common Drivers: + + - I2C: Restructured the I2C interface as necessary to eliminate some + thread-safety issues inherent in the legacy I2C interface design. + This effects the interface definition, all I2C clients, and all low- + level I2C drivers. I have used caution, but I still expect a change + of this magnitude to introduce some errors. Any bug reports of bug + fixes will be much appreciated. + - I2C_RESET: Eliminate up_i2creset(). It should not be a global + function; Now it is an I2C interface method. + - PCA555: Add logic to make the PCA555 driver thread safe. + - syslog: If syslog timestamping is enabled, don't try to get the time + if the timer hardware has not yet been initialized. + - AT24xx driver: Correct missing address calculation logic. From Frank + Benkert. + + * Networking: + + - Networking drivers that support CONFIG_NET_NOINTS: Fix a race + condition that can cause the TX poll timer to stop running. From + Manuel Stuhn. + - Timer Poll: Fix some logic when there are multiple network + interfaces. In this case, TCP timeout events can really only being + processed when the poll from the correct device is received. + + * Atmel SAMV7 Drivers: + + - SAMV7 USB HS device: The USB driver has had some issue that would + occasionally cause loss of packets. Back last December, a fix was + put in for this but the fix apparently worsens the problem; now + causing hangs. The basic problem is that the number of busy banks + (NBUSYBKS) status is not real time but is delayed. This was fixed; + now when the DMA completes and NBUSYBKS > 0, the NBUSYBK is + interrupt is enabled and the operations are deferred until NBUSYBKS + is truly zero. + + * Tools: + + - tools/testbuild.sh: .config files were not being updated because + (a) kconfig-conf was being called in the wrong directory and (b) + apps/Kconfig had not yet been created. Now uses 'make + olddefconfig'. + + * Applications: apps/system: + + - apps/system/i2c: The I2C tool now obeys it OS interfacing: it now + uses an I2C character driver to access the I2C bus. + - apps/system/cdcacm, usbmsc, and composite: Use new boardctl() + instead of calling directly in the OS when possible. + + * Applications: apps/netutils: + + - apps/netutils/dhcpd: DHCPD no longer calls directly into the OS but + uses the new network IOCTL commands to modify the ARP table. + + * Applications: apps/modbus: + + - apps/modbus/nuttx/portserial.c: Was not returning an error on + failure to open the device driver. From Olololshka kokoko. + + * Applications: apps/examples: + + - apps/examples/usbserial, composite, usbterm: Use new boardctl() + instead of calling directly in the OS when possible. There are + still a few bad OS calls for USB device interfaces that do not yet + have boardctl() commands. + + * Applications: apps/platform: + + - Moved C++ initialization logic out of the RTOS and into the + application space, specifically to apps/platform/board, where it + belongs. + +NuttX-7.16 Release Notes +------------------------ + +The 116th release of NuttX, Version 7.16, was made on June 1, 2016, +and is available for download from the Bitbucket.org website. Note +that release consists of two tarballs: nuttx-7.16.tar.gz and +apps-7.16.tar.gz. These are available from: + + https://bitbucket.org/nuttx/nuttx/downloads + https://bitbucket.org/nuttx/apps/downloads + +Both may be needed (see the top-level nuttx/README.txt file for build +information). + +Additional new features and extended functionality: + + * Core OS: + + - Power Management: Add activity domain to all PM interfaces and + driver callbacks. If CONFIG_PM_NDOMAINS == 1, then the legacy + behavior is preserved. If CONFIG_PM_NDOMAINS > 1, then multiple + PM domains are supported. This will allow separate control for + certain power management groups. For example, a network can be + shut down without affect an ongoing UI (and vice versa). + - board_app_initialize(): board_app_initialize() now accepts an + argument that may be used to support initialization in different + configurations. + + * File System and Block and MTD Drivers: + + - N25Qxxx: Add MTD support for Micron N25Qxxx family of QSPI flash. + From Dave (ziggurat29). + - SST26F: Add an MTD driver for SST26F spi/qspi flash devices (SPI + mode only). From Sebastien Lorquet. + - File Descriptor Detach: Add logic to detach a file structure from a + file descriptor. This is for use only within the OS. It permits an + open file or driver to be used across multiple threads. + + * Networking and Network Drivers: + + - listen()/accept(): Separate out psock_listen() and psock_accepti() + for internal, thread independent OS usage (i.e., without a socket + descriptor). + - VNC Server: Add support for a VNC server. This logic is code + complete and functional, but not well tested. + + * Graphics and Graphic Drivers: + + - Framebuffer driver: Add a display number to each interface in order + to support multiple display devices. + - VNC Server: Add support for a VNC server. This logic is code + complete and functional, but not well tested. + - LCD Backpack: Add support for PCF8574 LCD Backpack driver. This + driver supports an interface board that is based on the PCF8574 I/O + expander and supports the HD44780-based (or compatible) LCD modules. + There are a myriad of different vendors of such, but they are + principally the same, save wiring and minor features like jumpers + for I2C addresses. This driver supports known and unknown variants. + From Dave (ziggurat29). + + * Common Device Drivers: + + - RTC: Simplify the RTC interface. The old interface was way too + complex and was not fully implemented anywhere. + - BH1750FVI: Add a character driver for Rohm Ambient Light Sensor + BH1750FVI. From Alan Carvalho de Assis. + - CAN: Improve CAN error reporting. From Frank Benkert. + - aes.h: Modifications to the crypto API needed for LPC43xx. From + Alexander Vasiljev. + - ADC: Interface no longer uses global adc_receive() call. Added a + new bind() method to the ADC interface. Now the ADC upper half + driver will register its receipt-of-data callback. This change + allows the ADC lower half driver to be used with a differ ADC upper + half. + + * Simulation Platform: + + - Linux Host Networking: Enhance networking support for the + simulation under Linux. Includes updated support for Linux TUN/TAP, + and the addition of support for Linux bridge devices. From Steve. + + * ARMv7-A, ARMv7-R, and ARMv7-M: + + - ARMv7-M: Convert more assembly language files for use with the IAR + toolchain. From Kha Vo. + - ARMv7-A: Complete re-design of SMP-related logic to initialize each + CPUn, n > 0, when CONFIG_SMP=y. + + * Atmel SAMV7: + + - Add a JTAG config and ERASE config to Kconfig to set the + CCFG_SYSIO SYSIO Pins. From David Sidrane. + - System Reset: Add the up_systemreset interface to the samv7 arch. The + approach is slightly different in that: 1) It enables ARCH_HAVE_RESET + and allows the user to set if, and for how long, to drive External + nRST signal. It also does not contain a default board_reset, as that + really should be done in the config's src if CONFIG_BOARDCTL_RESET + is defined. From David Sidrane. + + * Atmel SAMV7 Boards: + + - SAMV71-XULT: Add configuration(s) that were be used to verify VNC + graphics output as well as mouse and keyboard input. + + * NXP Freescale i.MX6 Boards: + + - Sabre-6Quad: The basic i.MX6 port is complete. This is a minimal + port at present and probably still has some as-of-yet-undiscovered + issues. + - Sabre-6Quad: Basic SMP NSH configuration is now working. But this + is probably only because the SMP test case does not stress the + logic. There are know outstanding SMP issues as noted in the + Sabre-6Quad README.txt file. + + * NXP Freescale LPC43xx: + + - LPC4337jet100: Add definitions for the LPC4337jet100 chip. From + Alexander Vasiljev. + + * NXP Freescale LPC43xx Drivers: + + - AES: Add AES support. From Alexander Vasiljev. + + * STMicro STM32: + + - STM32 L4: Add configuration options to allow SRAM2 to be used for + heap, or not at all, and to zero-initialize it on OS start, or not + at all. From Dave dev@ziggurat29.com. + - STM32 L4: Add support for HSE and MSI clocks, and auto trim of MSI + to LSE (needed for USB). From Dave (ziggurat29) + - STM32 L4: Add support for unique id function to arch; modified board + to support unique id boardctl. From Dave (ziggurat29) + + * STMicro STM32 Drivers: + + - STM32 F4 RTC: Add a custom RTC driver with support for alarms. From + Neil Hancock. + - STM32 L4 QSPI: Add a QSPI driver with DMA support and (optional + memory mapped mode support. From Dave ziggurat29). + - STM32, STM32 L4, and STM32 F7 Serial: Add support for compliant + SD-style breaks. From David Sidrane. + - STM32 L4 CAN: Add CAN support for STM32L4. From Sebastien Lorquet. + - STM32 1-Wire: Add support for a custom 1-wire driver. The serial + driver already supports a 1-wire interface, but this driver uses the + same serial logic to implement a lower half driver much like the + I2C lower half driver.

From + Sbastien Lorquet. + +Works-In-Progress: + + * IEEE802.14.5/6LowPAN. Hooks and framework for this effort were + introduced in NuttX-7.15. Work has continued on this effort on + forks from the main repositories, albeit with many interruptions. + The completion of this wireless feature will postponed until at + least NuttX-7.17. + + * i.MX6 SMP. Partially functional, but there is more that still + needs to be done. + +Bugfixes. Only the most critical bugfixes are listed here (see the +ChangeLog for the complete list of bugfixes and for additional, more +detailed bugfix information): + + * Core OS: + + - Various places: Search for places where a stray semicolon following + an if condition cause the if body to be executed unconditionally. + Fixes in all SAM DMA logic, unionfs, OS signalling logic, and others. + - enter/leave_critical_section() may attempt to access task lists + before they have been initialized in the SMP configuration. + + * File System/Block Drivers: + + - SMART MTD: Return code of smart_scan not checked, can cause success + result in failure case, leading to 'dev' pointer being invalid. From + Dave (ziggurat29) + - mount: Fix a backward debug assertion. Noted by David Sidrane. + + * Common Drivers: + + - NRF24L01: Fix backward calculation of relative frequency. Noted by + Henry Zhang. + - PCA9555 I/O expander: Fix an error in the PCA9555 driver: Under + certain error conditions, interrupts were not being re-enabled. + Sebastien Lorquet. + - ADS1255: Must not do SPI access from interrupt handler. Use the + worker thread instead. Must also lock the SPI bus before using it. + - Several SPI-based drivers modified. All drivers that use SPI must + call SPI_LOCK and SPI_UNLOCK. This is not optional. + - MS583730: Fix a bug in crc computation for ms583730. Implement + POSIX read. + + * Atmel SAMV7: + + - Fix typo in MATRIX register definitions. From Stefan Kolb. + - SAMV7 Tickless Mode: This is a fix to a problem in the handling of + the oneshot timer. Due to a wrong assumption concerning the behavior + directly after the start of the timer/counter the function + sam_oneshot_cancel() calculates the wrong remaining time. The code + assumes that the counter register is zero directly after the start + of the timer, but this is not true. To start the time/counter a + software trigger is invoked, this trigger starts the timer/count and + sets the counter register to zero, but the reset of the counter + register is not performed instantly. According to the datasheet: + "The counter can be reset by a trigger. In this case, the counter + value passes to zero on the next valid edge of the selected clock." + Thus the counter is set to zero between 0 and USEC_PER_TICK + microseconds after the clock was started. + In my fix I use the freerun count value to determine if at least one + tick passed since the start of the timer and thus if the value of + the oneshot counter is correct. I also tried to use the function + up_timer_gettime() to achieve this but, at least if compiled with + no optimization the problem vanishes without using the value of the + function, the function call takes too long. + Another problem treated in the fix is that if the oneshot timer/counter + is canceled, we only know the remaining time with a precision of + USEC_PER_TICK microseconds. This means the calculated remaining time + is between 0 and USEC_PER_TICK microseconds too long. To fix this I + subtract one tick if the calculated remaining time is greater than + one tick and otherwise set the remaining time to zero. By doing so + the measured times are much more precise as without it. From Stefan + Kolb. + + * Atmel SAMA5: + + - SAMA5: Stefan Kolb's change to the SAMV7 Oneshot Timer should also + be applied to the SAMA5 oneshot time since the drivers are identical. + + * Atmel SAM3/4: + + - SAM3/4: Stefan Kolb's change to the SAMV7 Oneshot Timer should also + be applied to the SAM3/4 oneshot time since the drivers are identical. + + * Atmel SAMV7 Drivers: + + - SAMV7 TWIHS (as well as SAM3/4 and SAMA5: Ensure that the TWIHS + (i2c) hw get's its clock set when the sequence of + sam_i2cbus_initialize(), sam_i2cbus_uninitialize(), then + sam_i2cbus_initialize() or twi_reset() is called. I found this a + while back in the stm32 family, so there may be more arch-es with + this sort of bug. I suppose any driver that has the notion of "do + not set the freq if it is already set" could be suspect. From David + Sidrane. + - USBHS Device: Remove disabling of whole USB on suspend of USBHS. + This fix removes the disabling of the whole USB peripheral on + suspend interrupt. Its enough to freeze the clock instead. When + disabling the whole peripheral, the next wakeup-interrupt comes up + with an disabled clocking. The unfreeze clock has no effect, because + the master clock is disabled. This makes all registers, including + the IDR unwriteable and the IRQ falls in an endless loop blocking + the whole system. Furthermore the disabling of the peripheral clock + prevents hotplugging or reconnecting the USB. From Frank Benkert. + - MCAN: Fix missing unlock of device in MCAN mcan_txempty(). From + Frank Benkert. + + * STMicro STM32: + + - STM32 L4 Clocking: Problem with resetting backup domain clears + clocking options set up before in *rcc.c use INITS flag to avoid + magic reg value to detect power up reset state of RTC correct a + problem clearing interrupt flags (they weren't) which prevented an + alarm from ever being used more than once per reset cycle. From + Dave (ziggurat29) + + * STMicro STM32 Drivers: + + - STM32L4 SPI: That STM32Lr SPI driver is quite different. They now + handle frames of arbitrary size between 4 and 16 bits. It was broken + before a new bit has to be set (RX fifo threshold) to handle <= 8-bit + transactions. If not set, the default is 16-bit packed >=8-bit + frames and the RXNE bit is never set (it is set when 16-bits are + received). weird things as always. This also add 8-bit access + routines to the data register, because a 16-bit access to the data + register when the frame size is below 9 bits is interpreted as a + packed dual frame exchange. Sebastien Lorquet. + - STM32: Correct some bad commits that broke the LTDC display example. + From Marco Krahl. + - STM32 F4 RTC: Fix logic in F4 RTCC driver that prevent ALARM + interrupt. From Neil Hancock. + - STM32 F1 ADC: Fix STM32 ValueLine ADC IRQ number selection.

Note +that release consists of two tarballs: nuttx-7.17.tar.gz and +apps-7.17.tar.gz. These are available from: + + https://bitbucket.org/nuttx/nuttx/downloads + https://bitbucket.org/nuttx/apps/downloads + +Both may be needed (see the top-level nuttx/README.txt file for build +information). + +Additional new features and extended functionality: + + * File System and Block and MTD Drivers: + + - drivers/mtd: Add a driver of IS25xP SPI flash devices. Based on + sst25xx driver. From Marten Svanfeldt. + + * Networking and Network Drivers: + + - Break out internal interface psock_ioctl(). + + * Common Device Drivers: + + - PTYs: Added support for pseduo-terminals: Device drivers that can be + used for communications between tasks (usually with re-directed I/O). + Based on existing pipe logic. + - Button upper half driver: Added support for poll(). + - CAN: Add support for poll. From Paul Alexander Patience. + - GPIO: Add support for a simple GPIO driver. It supports only pre- + configured input, output, and interrupting pins with basic input and + output operations. Interrupt events can lead to notification via a + signal. + - I/O Expander: Shadow-Mode: The output- and configuration registers of + the IO-Expander are held in the microcontrollers memory and only + written to the IO-Expander. This reduces bus traffic and is more + error-proof than the normal read-modify-write operation. Retry Mode: + If enabled and an error occurs while writing to the IO-Expander the + current transmission is automatically repeated once. From Michael + Spahlinger. + - Pipes/FIFOs: Add support to allocating different sizes for pipe and + fifo buffers. Adds mkfifo2() and pipe2() which are just like mkfifo() + and pipe(), but allow control of the size of the underlying, in-memory + circular buffer. Move pipe() and mkpipe() to the C library, they are + no longer core OS interfaces. Capability currenty used only by PTY + logic to support, configurable, smaller buffers for PTYs. + + * SYSLOG/Debug Output: + + - SYSLOG: Consolidated all SYSLOG logic in drivers/syslog. Added an + abstraction layer that supports: (1) redirection of SYSLOG outpout. + This is usually so that you can boot with one SYSLOG output but + transition to another SYSLOG output when the OS has initialialized, + (2) adds common serialization of interrupt output as a configuration + option. Without this configuration setting, interrupt level output + will be asynchronous. And (3) vsyslog is now a system call and is + usable with other-than-FLAT builds. + - SYSLOG: syslog() will now automatically redirect output to + lowsyslog() if called from an interrupt handler. + - Extended SYSLOG logic so that we can send SYSLOG output to a file. + - SYSLOG character device channel will now expand LF to CR-LF. + Controllable with a configuration option. + - Add a SYSLOG character device that can be used to re-direct output + to the SYSLOG channel (Not be be confused the SYSLGO output to a + character device). + - Debug features are now enabled separately from debug output. + (1) CONFIG_DEBUG is gone. It is replaced with CONFIG_DEBUG_FEATURES. + (2) The macros dbg() and vdbg() have renamed as _err() and _info(), + respectively. This also applies to all of the variants as well, + XXdbg() and XXvdbg(). (3) Add a new debug level, _warn() (and + all variants XXwarn(), XXvwarn(), etc.). (4) Debug assertions can + now be enabled separately from debug output. (5) You can now enable + subsystem/device driver debug output at different output levels. For + example, CONFIG_DEBUG_FS no longer enables file system debug output + It enables general file system debug logic and enables selection of + CONFIG_DEBUG_FS_ERROR, CONFIG_DEBUG_FS_WARN, and CONFIG_DEBUG_FS_INFO. + - Since the SYSLOG layer now automatically handles low-level vs. + high-level output, the low-level (ll) variants of the debug macros + were eliminated. + - Reviewed all uses of *err(). These macro family should indicate + only error conditions. Convert *err() to either *info() or add + ERROR:, depending on if an error is reported. + - _alert(): New debug macro: _alert(). This is high priority, + unconditional output and is used to simplify and standardize crash + error reporting. + - Many CONFIG_DEBUG_* options did not have matching macros defined in + include/debug.h. Rather, there were various definitions scattered + throughout the sourse tree. These were collected together and + centralized with single macro definitions in include/debug.h + + * Simulation Platform: + + - Added the simulated QSPI (N25Q) flash to the simulation and extened + flash simulation capabilities to run with MTD drivers based on config + options (currently m25p, sst26 and w25). From Ken Pettit. + + * Atmel SAMV7 Drivers: + + - SPI: SPI-Freq. 40MHz; VARSELECT; hw-features This change adds the + following improvements: + + o Increase the allowed SPI-Frequency from 20 to 40 MHz. + o Correct and rename the "VARSELECT" option This option was + included in the code as "CONFIG_SPI_VARSELECT" but nowhere + defined in a Kconfig file. The change renames it to + "CONFIG_SAMV7_SPI_VARSELECT" and corrects the implementation + according the datasheet of Atmel. In short, this option + switches the processor from "fixed peripheral selection" + (single device) to "variable peripheral selection" (multiple + devices on the bus). + o Add a new Function to the interface to control the timing and + delays of the chip according the ChipSelect lines. This function + can control the delay between the assertion of the ChipSelect and + the first bit, between the last bit and the de-assertion of the + ChipSelect and between two ChipSelects. This is needed to tune + the transfer according the specification of the connected devices. + o Add three "hw-features" for the SAMV7, which controls the behavior + of the ChipSelect: + - force CS inactive after transfer: this forces a (short) de- + assertion of the CS after a transfer, even if more data is + available in time + - force CS active after transfer: this forces the CS to stay + active after a transfer, even if the chip runs out of data. + Btw.: this is a prerequisit to make the LASTXFER bit working + at all. + - escape LASTXFER: this suppresses the LASTXFER bit at the end + of the next transfer. The "escape"-Flag is reset automatically. + + From Frank Benkert + - TWISHS: Driver improvements from Michael Spahlinger. + - GPIO-Driver fixed for Open-Drain Pins: + + o sam_gpioread: Now the actual line level from the pin is read + back. This is extremely important for Open-Drain Pins, which + can be used bidirectionally + o Re-Implemented twi_reset-function and enhanced it so it can be + called from inside the driver (see next point) + o Glitch-Filter: Added a configuration option to enable the twi- + built-in glitch filter + o Added a "Single Master Mode": In EMC Testing the TWI-Bus got + stuck because the TWI-Master detected a Multi-Master access (but + there is no second master). With the option "Single Master" we + detect these events and automatically trigger a twi_reset. We + also do an automatic recovery if a slave got stuck (SDA stays + low). + + With the above changes IC-Bus reliability in harsh environments (eg. + EMC) is greatly improved. The small change in the GPIO-Driver was + necessary because otherwise you cannot read back the correct line + status of Open-Drain Outputs and this is needed by the twi_reset + function. From Michael Spahlinger + + * NXP Freescale LPC43xx Drivers: + + - EMC: Extend LPC43xx EMC code to support SDRAM on a dynamic memory + interface. From Vytautas Lukenskas. + + * NXP Freescale Kinetis: + + - Kinetis K64: Add basic support for the K64 family. I leveraged the + changes from https://github.com/jmacintyre/nuttx-k64f and merged + into the existing kinetis code with a lot of changes and additions + (like pin multiplexing definitions). + + * NXP Freescale Kinetis Drivers: + + - Add a KinetisUSB device controller driver. Derived from the pic32mx + usb driver, which uses the same usb controller. From kfazz. + - Kinetis pwm support, based on the KL pwm driver. From kfazz. + - Kinetis Ethernet: Add support for the KSZ8081 PHY. + - Kinetis Ethernet: Modified Ethernet driver to try all PHY addresses + and then only fail if the driver cannot find a usable PHY address. + This means that you no longer have to specific the PHY address in + advance. + - Kinetis Ethernet: Add support for CONFIG_NET_NOINTS. The driver no + longer runs the networking at interrupt level but can defer interrupt + work to the high-priority work queue. + + * NXP Freescale Kinetis Boards: + + - Teensy-3.x: Add USB support and a usbnsh configuration. + From kfazz (2016-06). + - Freedom-K64F: Add support for the NXP Freedom-K64F board at 120MHz. + This is primarily the work of Jordan Macintyre. I leveraged this + code from https://github.com/jmacintyre/nuttx-k64f which was, itself, + a leverage from the old K60 TWR configuration. This includes + significant corrections (LEDs, buttons, README, etc) and extensions + and updates to match more recent BSPs. + - Freedom-K64F: Added a configuration that supports networking. + + * STMicro STM32: + + - STM32 F1-4: Added support for the STM32F105R. From Konstantin + Berezenko. + - STM32 F4: Added support for the STM32FF76xxx and STM32FF7xx + families. From David Sidrane. + - STM32 F1-4: Add support for Tickless mode (two timer + implementation). From Max Neklyudov. + - STM32 L4: Add support for tickless OS, and incidentally timers, + PWM, oneshot, free-running.... From ziggurat29. + + * STMicro STM32 Drivers: + + - STM32 F1-4: Add the up_getc() function to STM32 in order to support + the minnsh configuration. From Alan Carvalho de Assis. + - STM32 F7: Add SPI driver. From David Sidrane. + - STM32 F7: Add SPI, I2C, and ADC drivers. From Lok Tep. + - STM32 L4: Add ioctls to set/get CAN bit timing in stm32l4. Add + ioctl hooks to allow future management of can id filters. From + Sebastien Lorquet. + - STM32 L4: Add some CAN mode IOCTL calls. These will be useful for + device autotest when the application boots. They are redundant + with the CONFIG_CAN_LOOPBACK option, which can now just be + interpreted as a default setting. From Sebastien Lorquet. + - STM32 F1-4: Port STM32L4 CAN IOCTLs to STM32. From Sebastien Lorquet. + - STM32 L4: Implementation of loopback IOCTLs. From Sebastien + Lorquet. + - STM32 F7: Added SDMMC1 support for stm32F7 74-75. From Lok Tep. + - STM32 F7: Add USB support. From Lok Tep. + - STM32 F7: Added PWR, RTC, and BBSRAM support for stm32f7. From David + Sidrane. + - STM32 F7: Added STMF7xxx RTC. From David Sidrane. + - STM32 F7: Added STM32F7 DBGMCU. From David Sidrane. + - STM32 L4: Port support for both RX FIFOs from STM32 CAN. From Paul + Alexander Patience. + + * STMicro STM32 Boards: + + - Added a minnsh configuration for the STM32F103-Minimum board. From + Alan Carvalho de Assis . + - Added support for the Nucleo-F767ZI board. From David Sidrane. + - Nucleo-144/Nucleo-F767ZI: Add test for STM32 F7 SPI. From David + Sidrane. + - Nucleo-144: Added SDMMC support to Nucleo-144. From David Sidrane. + - Olimex STM32-E4077: Add support for Olimex STM32 E407 board. From + Mateusz Szafoni. + - Nucleo-144: Added USB OTG device to Nucleo-144. From David Sidrane. + - Nucleo-144: Added bbsram test to Nucleo-144. From David Sidrane. + - STM32F4 Disovery: Add CAN support for STM32F4 Discovery. From + Matthias Renner. + - STM32F4 Disovery: added a canard configuration files. From + Matthias Renner. + - STM32F4 Discovery: Add FPU support for ostest for the STM32F4 + Disovery platform. From David Alessio. + - STM32L476 Discovery: Update stm32l476 disco to include init code for + smartfs and nxffs for cases where those fs are included in build. + From ziggurat29. + + * C Library/Header Files: + + - include/assert.h: Check if NDEBUG is defined. From Paul Alexander + Patience. + - assert.h: Define static assert for C++ usage. From Paul Alexander + Patience. + - Add crc64 support. From Paul Alexander Patience. + - hex2bin: Move the portable library portion of apps/system/hex2bin + the C library with the OS internals. It is used in certain internal + boot-loader builds. + - Add raise(). + - libm: This change should significantly improve the performance of + single precision floating point math library functions. The vast + majority of changes have to do with preventing the compiler from + needlessly promoting floats to doubles, performing the calculation + with doubles, only to demote the result to float. These changes only + affect the math lib functions that return float. From David Alessio. + - printf(): If there are no streams, let printf() fall back to use + syslog() for output. + - Move pipe() and mkpipe() to nuttx/libc, they are no + longer core OS interfaces. Capability currenty used only by PTY logi + to support, configurable, smaller buffers for PTYs. + - Move driver-related files from include/nuttx to include/nuttx/drivers. + Move driver related prototypes out of include/nuttx/fs/fs.h and into + new include/drivers/drivers.h. + - include /nuttx/lib: Move library-related files from include/nuttx to + include/nuttx/lib. + + * Build/Configuration System: + + - Custom Board Configuration: Add logic to support custom board + directories that include a Kconfig file. During the context phase + of the build, any Kconfig file in the custom board directory is + copied into configs/dummy, replacing the existing Kconfig file with + the target Kconfig file. + - Remove the includes/apps link to apps/include. It is no longer + used. From Sebastien Lorquet. + + * Tools: + + - tools/tesbuild.sh will now build NxWM configurations. + + * Appplication Build/Configuration System: + + - Change to the way that apps/ Kconfig files are generated in + order to better support reuse of the apps/ directory in NuttX + products. Changes include: Make the full tree use wildcards + make.defs, Add empty preconfig rules to 'leaf' makefiles, Use + directory.mk for recursive dir makefiles, Individual app kconfig + fixes, Recursive Kconfig autogeneration, Add kconfig files for + pcode and tiff, and fix a gitignore rule, From Sbastien Lorquet. + - apps/include directory structure reorganized. There are no longer + any header files in the apps/include/. directory. Rather, sub- + directories were added to match the partitioning of apps/ sub- + directories and the header files were moved into the appropriate + sub-directory. This change is intended to help with some changes + being considered by Sbastien Lorquet. + - Call all includes from to "bla/bla.h". From Sebastien + Lorquet. + - Add apps/include to include path in top-level Make.defs file. + + * Applications: apps/nshlib: + + - Make NSH net-initialization be a configuration option. From Marten + Svanfeld. + - Add NTP client initialization in NSH network startup logic. From + David S. Alessio . + - 'ps' command now prints out the stack usage if stack coloration is + enabled. From Frank Benkert. + - Allow stack usage to be disabled on constrained systems. From David + Sidrane. + + * Applications: apps/netutils: + + - NTP Client: Add retries. From David S. Alessio. + - NTP Client: The NTP client will now optionally use pool.ntp.org as + the NTP server; and reset the retry count upon success -- more robust. + From David Alessio. + - ESP8266: Add logic to set the BAUD rate. From Pierre-noel Bouteville. + - ESP8266: In Kconfig, select ARCH_HAVE_NET when NETUTILS_ESP8266 is + selected. This allows, among other things, support for network debug + output. From Pierre-noel Bouteville. + + * Applications: apps/fsutils: + + - flash_eraseall: IOCTL wrapper for MDCIO_BULKERASE command. Was in + nuttx/drivers/mtd. Moved to apps/fsutils because the call directly into + the OS was incorrect. + + * Applications: apps/canutils: + + - canlib: Basic CAN utility library. From Sebastien Lorquet. + + * Platforms: apps/system: + + - flash_eraseall: Now uses the IOCTL wrapper at apps/fsutils/flash_eraseall. + + * Platforms: apps/platform: + + - Add platform files for Olimex STM32 E407. From Mateusz Szafoni. + + * Applications: apps/examples: + + - apps/examples/canard: Add canard example application. From + Matthias Renner. + - apps/examples/pty_test: PTY test program. From Alan Carvalho de + Assis. + +Works-In-Progress: + + * IEEE802.14.5/6LowPAN. Hooks and framework for this effort were + introduced in NuttX-7.15. Work has continued on this effort on + forks from the main repositories, albeit with many interruptions. + The completion of this wireless feature will postponed until at + least NuttX-7.18. + + * i.MX6 SMP. Partially functional, but there is more that still + needs to be done. + +Bugfixes. Only the most critical bugfixes are listed here (see the +ChangeLog for the complete list of bugfixes and for additional, more +detailed bugfix information): + + * Core OS: + + - semaphores: Need to set errno to EINVAL on errors in sem_post() + and sem_wait(). From Paul Alexander Patience. + + * File System/Block Drivers/MTD Drivers: + + - Several MTD FLASH drivers nullify the freed 'priv' structure and + failed to return NULL as stated in the comments. Result, will + operate on a NULL pointer later. Noted by David Sidrane. + - VFS ioctl(). Per comments from David Sidrane, file_ioctl() should + not return succeed if the ioctl method is not supported. It + probably should return ENOTTY in that case. + - SST26 Driver: Before accessing the sst26 flash, the "Global Unlock" + command must me executed, which I do in the sst26 driver. BUT re- + reading the datasheet, the WREN instruction is required to enable + the execution of this command. This was not done. I have no idea how + the driver currently works except by chance. The writes should never + happen at all, the flash is half-enabled! From Sebastien Lorquet. + - N25Qxx Driver: Alter the notion of 'blocksize' to be equivalent to + 'flash write page size' in order to align with assumptions in the + smartfs driver (at least, maybe other things do as well). Correct a + bug that was previously masked by having blocksize=eraseblocksize + which would cause buffer overflows and delicious hardfaults. + Trivial spelling changes in comments, etc. From ziggurat29. + - SmartFS: Fix a 32-byte memory leak. From Ken Pettit. + - SMART MTD layer: Fixes freesector logic error when sectorsPerBlk=256, + adds DEBUGASSERT for invalid geometry and additional memory debug + logic. Also fixes the dangling pointer on error bug. From Ken + Pettit. + + * Common Drivers: + + - USB CDC/ACM Device Class: cdcacm_unbind leaks write request objects. + This arises due to freeing the bulk IN endpoint before the loop + that frees the requests via cdcasm_freereq. That function checks + the parameters and skips the freeing if either is NULL. Freeing + the bulk IN enpoint will cause the first param to be NULL, thereby + bypassing the free operation. To fix, I moved the release of the + bulk IN endpoint until after to loop (much as was the case for the + OUT and read requests, which did not exhibit the problem). From + ziggurat29. + - Pipes and FIFOs: Add missing configuration for pipe ring buffer + size. From Frank Benkert. + - UART 16550: Handle when CONFIG_SERIAL_UART_ARCH_IOCTL is not + enabled. From Heath Petersen. + - Common Serial Upper Half: Fix a race condition noted by Stefan + Kolb. Between the test if the TX buffer is full and entering a + critical section, bytes may be removed from the TX buffer making + the wait unnecessary. The unnecessary wait is an inefficiency, + but not really a problem. But with USB CDC/ACM it can be a problem + because the entire TX buffer may be emptied when we lose the race. + If that happens that uart_putxmitchar() can hang waiting for data + to be removed from an empty TX buffer. + - USB MSC Device Class: Add locks when removing request from queue. + From Wolfgang Reissnegger. + - USB MSC Device Class: Fix reversed logic on waiting for SCSI thread + start. The scsi thread was waiting for the wrong condition. + However, this was masked by the fact that the code creating the + scsi thread was also holding usbmsc_scsi_lock(priv) while + initializing data, hence this lock synchronized the scsi thread + start with init completion. From Wolfgang Reissnegger. + + * Graphics and Graphic Drivers: + + - Correct conditional compilation in ST7565 LCD driver. From Pierre- + noel Bouteville + + * Networking: + + - In both IPv6 and IPv4 incoming logic: (1) Should check if the + packet size is large enough before trying to access the packet + length in the IP header. (2) In the comparison between the IP + length and the full packet length, need to subtract the size of + he link layer header before making the comparison or we will get + false positives (i.e., the packet is really too small) + - TCP Networking: While working with version 7.10 I discovered a + problem in TCP stack that could be observed on high network load. + Generally speaking, the problem is that RST flag is set in + unnecessary case, in which between loss of some TCP packet and its + proper retransmission, another packets had been successfully sent. + The scenario is as follows: NuttX did not receive ACK for some sent + packet, so it has been probably lost somewhere. But before its + retransmission starts, NuttX is correctly issuing next TCP packets, + with sequence numbers increasing properly. When the retransmission + of previously lost packet finally succeeds, tcp_input receives the + accumulated ACK value, which acknowledges also the packets sent in + the meantime (i.e. between unsuccessful sending of lost packet and + its proper retransmission). However, variable unackseq is still set + to conn->isn + conn->sent, which is truth only if no further + packets transmission occurred in the meantime. Because of incorrect + (in such specific case) unackseq value, few lines further condition + if (ackseq <= unackseq)is not met, and, as a result, we are going to + reset label. From Jakub Lagwa. + + * ARMv7-M: + + - ARM stack check: Fix double fault on IDLE task with stack size = 0. + From David Sidrane. + + * Atmel SAMV7 Drivers: + + - CAN: CAN Message Filtering fixed: (1) stdfilters didn't work because + the filter was never enabled (wrong number of bits to shift), and + (2) Filters were never used because the configuration register + cannot be written without using the initialization mode.

This problem is caused by an incorrect + handling of the endpoint state in the USB driver sam_usbdevhs. This + leads under some circumstances to situations in which an DMA + transfer is setup while a previous DMA transfer is currently active. + Amongst other things I introduced the new endpoint state + USBHS_EPSTATE_SENDING_DMA for the fix.

From Sebastien Lorquet. + + * Build/Configuration System: + + - Build system: This change fixes a build problem that only occurs + when reconfiguring from Linux to Windows or vice-versa. It is a + problem that was present but not usually experienced until two + things happened: (1) The pre_config target was added to run before + the menconfig operation and (2) the context target was added before + the pre_config target in order to set up the correct symbolic links + (in the apps/platform directory) needed by the pre_config target. + But then now if you start with a Linux system and run 'make + menuconfig' to switch to Linux, the context target will execute + first and set up POSIX style symbolic links before doing the + menuconfig. Then after the menuconfig, the make will fail on + Windows if you are using a Windows native toolchain because that + native toolchain cannot follow the Cygwin- style symbolic links. + The fix here is to also execute the clean_context AFTER executing + menuconfig. A lot more happens now: It used to be that doing + 'make menuconfig' only did the menuconfig operation. Now it does + context, pre_config, menuconfig, clean_context. Not nearly as + snappy as it used to be. + - Need to build the drivers/ directory even it file descriptors are + not supported. There are things in the drivers/ directory that are + still needed (like SYSLOG logic). + - Remove all inclusion of header files from the apps/include + directory from NuttX core logic. There should be no dependency on + logic within NuttX on logic within apps/. This caused a lot of + reshuffling of logic: binfmt pcode support, usbmonitor is now a + kernel thread, TZ/Olson database moved to libc/zoneinfo. + + * Application Build/Configuration System: + + - Make sure that APPNAME is defined in all Makefiles that generate + applications.

Note +that release consists of two tarballs: nuttx-7.18.tar.gz and +apps-7.18.tar.gz. These are available from: + + https://bitbucket.org/nuttx/nuttx/downloads + https://bitbucket.org/nuttx/apps/downloads + +Both may be needed (see the top-level nuttx/README.txt file for build +information). + +Additional new features and extended functionality: + + * Core OS: + + - Add standard adjtime() interface and basic timekeeping support. + Normally used with an NTP client to keep system time in + synchronization. From Max Neklyudov. + - Use the oneshot timer with optional entropy to measure CPU load if + so configured. + + * File System and Block and MTD Drivers: + + - Add Fujistu MB85RS256B ramtron support.

From Alan Carvalho + de Assis. + - Add a new ioctl command (set MAXPOS) for Tiva QEI. From Young. + + * Other Common Device Drivers: + + - I/O Expander: Remove hard-coded PCA9555 fields from ioexpander.h + definitons. Add support for an attach() method that may be used + when any subset of pin interrupts occur. + - I/O Expander Interface: Encode and extend I/O expander options to + include interrupt configuration. + - PCA9555 Driver: Replace the signalling logic with a simple callback + using the new definitons of ioexpander.h. This repartitioning of + functionality is necessary because (1) the I/O expander driver is + the lower-lower part of any driver that uses GPIOs (include the GPIO + driver itself) and should not be interacting directly with the much + higher level application layer. And (2) in order to be compatible + with the GPIO driver (and any arbitrary upper half driver), the + PCA9555 should not directly signal, but should call back into the + upper half. The upper half driver that interacts directly with the + application is the appropriate place to be generating signal. + - Add a skeleton I/O Expander driver (based on the PCA9555 driver). + - Add PCF8574 I/O Expander driver. + - GPIO driver: Add IOCTLs to get the pin type and to unregister a + signal handler. + - Add a GPIO lower-half driver that can be used to register a GPIO + character driver for accessing pins on an I/O expander. + - Add an SPI helper function that encapsulates and manages a sequence + of SPI transfers. + - Add an SPI character driver that will permit access to the SPI bus + for testing purposes. + - Add oneshot timer lower half interface definition. + - Add an upper-half, oneshot timer character driver. + - Add Audio Tone Generator for NuttX.

The + Motorola MDK is based off of an earlier version of NuttX. + This only provides a basic NSH shell. From Jim Wylder. + - STM32 F4 Discovery: Add support for XEN1210 3D-board. From Alan + Carvalho de Assis. + - stm32f103-minimum: Add stm32_bringup support and userled example to + STM32F103 Minimum board. From Alan Carvalho de Assis. + - Add support for qencoders on various nucleo boards. From Sebastien + Lorquet. + - olimex-stm32-e407: Add some networking configurations.

From Sebastien Lorquet. + - Add system() to stdlib.h. Actual implementation is in + apps/system/system. + + * Build/Configuration System: + + - Rename arch/sh to arch/renesas. + - Remove contactless drivers from drivers/wireless to drivers + contactless. From Sebastien Lorquet. + - Move all modem-related IOCTL commands to a common file to assure + that they will be unique. + + * Tools: + + - Add sethost.sh. This is a script that you can use to quickly + change the host platform from Linux to Windows/Cygwin. Might save + you a lot of headaches. + + * Applications: apps/nshlib: + + - Add logic to support an NSH-specific system command. + - Add printf command to NSH, e.g., controlling /dev/userleds from + command line: nsh> printf \x01 > /dev/userleds. From Alan Carvalho + de Assis. + + * Platforms: apps/system: + + - Port tee command from NetBSD. + - Add a generic system command.

From Alan Carvalho de Assis. + - Add Oneshot timer example. + - Add a simple test of the system command. + +Works-In-Progress: + + * IEEE802.14.5/6LowPAN. Hooks and framework for this effort were + introduced in NuttX-7.15. Work has continued on this effort on + forks from the main repositories, albeit with many interruptions. + The completion of this wireless feature will postponed until at + least NuttX-7.19. + +Bugfixes. Only the most critical bugfixes are listed here (see the +ChangeLog for the complete list of bugfixes and for additional, more +detailed bugfix information): + + * Core OS: + + - Explicitly initialize the group tg_exitsem with sem_init(). The + existing logic worked because the correct initialization value is + all zero, but it is better to initialize the semaphore explicitly. + - The TCB nchildren field should not be incremented when pthreads are + created. + - Move fields related to parent/child task relationship out of TCB + into group structure where they belong. Child is a group, not a + thread. + - mq_send() was not setting the errno value on certain failures to + allocate a message. + - Define 'group' even if HAVE_GROUPID is not set. From Mateusz + Szafoni. + - Vector table should have dimension NR_IRQS, not NR_IRQS+1. From + Sagitta Li. + - pthreads: When a pthread is started, there is a small bit + of logic that will run on the thread of execution of the new + pthread. In the case where the new pthread has a lower + priority than the parent thread, then this could cause both the + parent thread and the new pthread to be blocked at the priority of + the lower priority pthread (assuming that CONFIG_PRIORITY_INHERITANCE + is not selected). This change temporarily boosts the priority of the + new pthread to at least the priority of the new pthread to at least + the priority of the parent thread. When that bit of logic has + executed on the thread of execution of the new pthread, it will then + drop to the correct priority (if necessary) before calling into the + new pthread's entry point. + + * File System/Block Drivers/MTD Drivers: + + - FAT performance improvement. In large files, seeking to a + position from the beginning of the file can be very time consuming. + ftell does lssek(fd, 0, SET_CURR). In that case, that is wasted + time since we are going to seek to the same position. This fix + short-circuits fat_seek() in all cases where we attempt to seek to + current position. Suggested by Nate Weibley. + - MTD: Fixed cloned typos in several FLASH drivers. From Aleksandr + Vyhovanec. + - mount: Corrects a bad assertion noted by Pierre-noel Bouteville. + Also fixes a reference counting problem in an error condition: + When the mountpoint inode is found but is not an appropriate + mountpoint, the reference count on the inode was not being + decremented. + + * Common Drivers: + + - Various serial drivers: Fix FIONWRITE and add FIONSPACE. All + implementations of FIONWRITE were wrong. FIONWRITE should return + the number of bytes waiting in the outgoing send queue, not the free + space. Rather, FIONSPACE should return the free space in the send + queue. + - Add missing prototype for btn_lower_initialize(). + - Make DAC sample structure packed. From Marc Recht. + + * Networking: + + - TCP: tcp_ipvX_bind() not actually using the port selected with + port==0. Also removes duplicate call to pkt_input(). Issues noted + by Pascal Speck. + - drivers/net: NET_TUN=y => NET_MULTIBUFFER=y. From Vladimir + Komendantskiy. + - slip driver: Fix calculations using MSEC_PER_TICK. If + USEC_PER_TICK is less than 1000, then MSEC_PER_TICK will be + zero. It will be inaccurate in any case. + + * Atmel SAM3/4 Drivers: + + - SAM3/4 GPIO: Enable peripheral clock for GPIO port when GPIO is + configured as input. The value of a GPIO input is only sampled when + the peripheral clock for the port controller the GPIO resides in is + enabled. Therefore we need to enable the clock even when polling a + GPIO. From Wolfgang Reissnegger. + - All SAM Ethernet Drivers: Add support so that the drivers can be + built with CONFIG_NET_MULTIBUFFER=y. + - SAM3/4: Fix GPIO pull-up/down code. Enabling the pull-down resistor + while the pull-up resistor is still enabled is not possible. In this + case, the write of PIO_PPDER for the relevant I/O line is discarded. + Likewise, enabling the pull-up resistor while the pull-down resistor + is still enabled is not possible. In this case, the write of + PIO_PUER for the relevant I/O line is discarded. From Wolfgang + Reinegger. + + * Atmel SAMV7 Drivers: + + - All SAM Ethernet Drivers: Add support so that the drivers can be + built with CONFIG_NET_MULTIBUFFER=y. + - SAM GPIO: Apply Wolfgang's change for SAM3/4 to SAMA5 and SAMV7. + + * Atmel SAMA5: + + - Add missing oneshot max_delay method. + - All SAM Ethernet Drivers: Add support so that the drivers can be + built with CONFIG_NET_MULTIBUFFER=y. + - SAM GPIO: Apply Wolfgang's change for SAM3/4 to SAMA5 and SAMV7. + + * NXP Freescale LPC43xx Drivers: + + - LPC43xx serial: Fix typos in LPC43 serial driver. Found by Vytautas + Lukenskas. + - LPC43xx Serial: There are some small problems in LPC43xx RS485 mode + configuration. In particular: (1) UART0,2,3 do not have DTR pins + (different from UART1), so, Kconfig needs to be adjusted. (2) + lpc43_uart.c in RS485 mode only configures DIR pin, but doesn't + enable pin output for UART0,2,3. (3) should be option to reverse DIR + control pin output polarity. (4) lpc43xx/chip/lpc43_uart.h doesn't + have USART3 definitions. NOTE: I didn't modified and didn't tested + USART1, as it has different hardware. From Vytautas Lukenskas. + From Vytautas Lukenskas. + + * SiLabs EFM32 Drivers: + + - EFM32 SPI drivers adopted incompatible conventions (See STM32 for + details of the issue). + + * STMicro STM32 Drivers: + + - STM32, STM32 L4, and EFM32 SPI drivers adopted incompatible + conventions somewhere along the line. They set the number of bits + to negative when calling SPI_SETBITS which had the magical side- + effect of setting LSB first order of bit transmission. This is not + only a hokey way to pass control information but is supported by no + other SPI drivers. This change three things: (1) It adds + HWFEAT_LSBFIRST as a new H/W feature. (2) It changes the + implementations of SPI_SETBITS in the STM32 and EFM32 drivers so + that negated bit numbers are simply errors and it adds the + SPI_HWFEATURES method that can set the LSB bit order, and + (3) It changes all calls with negative number of bits from all + drivers: The number of bits is now always positive and + SPI_HWFEATURES is called with HWFEAT_LSBFIRST to set the bit order. + - Add missing SPI2 and SPI3 support for STM32F3F3. Add STM32F37XX DMA + channel configuration. For STM32F37XX, SYSCFG_EXTICR_PORTE defined + twice. From Alan Carvalho de Assis. + - STM32: Make stm32_pwr_enablebkp thread safe.

From + Young. + - Tiva Ethernet: Needs support for CONFIG_NET_MULTIBUFFER=y. + + * C Library/Header Files: + + - lib_dumpbuffer() now prints a large on-stack buffer first to avoid + problems when the syslog output is prefixed with time. From + Pierre-noel Bouteville. + - libc/math: This fixes the following libc/math issues: (1) asin[f l]() + use Newtons method to converge on a solution. But Newtons method + converges very slowly (> 500,000 iterations) for values of x close to + 1.0; and, in the case of asinl(), sometimes fails to converge (loops + forever). The attached patch uses an trig identity for values of + x > sqrt(2). The resultant functions converge in no more than 5 + iterations, 6 for asinl(). (2) The NuttX erf[f l]() functions are + based on Chebyshev fitting to a good guess. The problem theres a + bug in the implementation that causes the functions to blow up with + x near -3.0. This patch fixes that problem. It should be noted that + this method returns the error function erf(x) with fractional error + less than 1.2E-07 and thats fine for the float version erff(), but + the same method is used for double and long double version which + will yield only slightly better precision. This patch doesn't + address the issue of lower precision for erf() and erfl(). (3) a + faster version of copysignf() for floats is included. From David S. + Alessio. + - strtod() was not returning endptr on error conditions. + - libc/math: floor(), floorf(), and floorl(): Fix logic error. Was + not correctly handling negative integral value. + - isatty() should be prototyped in unstid.h, not termios.h. From + Sebastien Lorquet. + - nxglib: Fix handling of near-horizontal lines of width 1 in + nxgl_splitline(). Missing handling for degenerate condition caused + width 1 lines such as (0, 0) - (100, 10) to have gaps in the + drawing. From Petteri Aimonen. + + * Build/Configuration System: + + - Top-Level Makefiles: Fix a chicken-and-egg problem. In the menuconfig + target, the context dependency was executed before kconfig-mconf. That + was necessary because the link at apps/platform/board needed to be set + up before creating the apps/Kconfig file. Otherwise, the platform + Kconfig files would not be included. But this introduces the chicken- + and-egg problem in some configurations. In particular: (1) An NX + graphics configuration is used that requires auto-generation of + source files using cpp, (2) the configuration is set for Linux, but + (3) we are running under Cygwin with (4) a Windows native toolchain. + In this case, POSIX-style symbolic links are set up but the Windows + native toolchain cannot follow them. The reason we are running + 'make menuconfig' is to change from Linux to Cygwin, but the target + fails. During the context phase, NX runs CPP to generate source files + but that fails because the Windows native toolchain cannot follow + the links. Checkmate. This was fixed by changing all of the make + menuconfig (and related) targets. They no longer depend on context + being run. Instead, they depend only on the dirlinks target. The + dirlinks target only sets up the directory links but does not try + to run all of the context setup; the compiler is never invoked; no + code is autogenerated and things work. + - CXXFLAGS: Add -fcheck-new whenever -fno-exceptions is used. From + Beat Kng. + + * Tools + + - tools/refresh.sh: Recent complexities added to apps/ means that + configuration needs the correct Make.defs file in place in order to + configure properly. + - tools/kconfig2html.c: Update to handle absolute paths when sourcing + Kconfig files. + - tools/mkfsdata.pl was still generating the old-style apps/include + inclusion paths. + + * Application Build/Configuration System: + + - Add DIRLINK and DIRUNLINK tool definitions to apps/Make.defs. + + * apps/nshlib: + + - Fix FIFO_SIZE vs PIPE_SIZE. + - Fix hex representation of IP address in Kconfig.

From Sebastien + Lorquet. + + * apps/gpsutils: + + - Fix an error minmea.

Note +that release consists of two tarballs: nuttx-7.19.tar.gz and +apps-7.19.tar.gz. These are available from: + + https://bitbucket.org/nuttx/nuttx/downloads + https://bitbucket.org/nuttx/apps/downloads + +Both may be needed (see the top-level nuttx/README.txt file for build +information). + +Additional new features and extended functionality: + + * Core OS: + + - sched/semaphore, sched/phread/, libc/semaphore, libc/pthread: Add + pthread_mutexattr_get/set_protocol and non-standard + sem_get/set_protocol. These may use to enable or disable priority + inheritance on a single semaphore. + - Spinlocks: Added capability to provide architecture-specific memory + barriers. + - SMP: Add spin_trylock(). Use this in conditions where other CPUs need + to stopped but we cannot call enter_critical_section(). + - sched note: Extend OS instrumentation to include some SMP events. + Also add spinlock instrumentation; In SMP configurations, add a + filter mask to log only notes from certain CPUs. + - sched note: Permit spinlock and critical section notes in in-memory + buffer iff sched_not_get() interfaces is disabled. + - sched note: Add additional note to see if/when CPU is started in SMP + mode. + - sched note: Record ID enumeration now results on constant values; ID + values do not change with configuration. This makes writing post-processing software much easier. + - boardctl: Add new boardctl() command, BOARDIOC_NX_START, to start the + NX server as a kernel thread. + - pthreads: Add pthread_cleanup_push() and pthread_cleanup_pop(). + - pthreads: Added pthread_setcanceltype() and pthread_testcancel(). + - pthreads: Add support for cancellation points. + - task_delete() now obeys all cancellation point semantics. + - Add task_setcancelstate(), task_setcanceltype(), and + task_testcancel().

From + Ramtin Amin. + - Misoc LM32 Qemu: Integrate network support into configs/misoc/hello. + From Ramtin Amin. + - Misoc LM32 Qemu: Remove configs/misoc/include/generated directory. I + suppose the intent now is that this is a symbolic link? DANGER! + This means that you cannot compile this code with first generating + these files a providing a symbolic link to this location! There is a + sample directory containing generated sources. This is really only + useful for performing test builds. You really must generate the Misoc + architecture for a real-life build. From Ramtin Amin. + + * NXP Freescale i.MX6 Drivers: + + - i.MX6: Add an untested SPI driver taken directly from the i.MX1 port. + + * NXP Freescale Kinetis: + + - Kinetis: Added missing headers. Kinetis broke out SPI to + kinetis/kinetis_spi.h. Broke out DMA to use the modern Nuttx chip + inclusion - still STUBS. Add Kinetis support for ARMV7-M Common + Vector and FPU. Allow CONFIG_ARMV7M_CMNVECTOR, + CONFIG_STACK_COLORATION, CONFIG_ARCH_FPU. Fix i2c driver offset + swapped for value in kinetis_i2c_putreg.

The board support on this is pretty + thin, but it seems like maybe a good idea to get the base RISC-V stuff + in since there are people interested in it. From Ken Pettit. + + * STMicro STM32 Drivers: + + - STM32 F3: Implemention of the STM32 F37xx SDADC module. There are + also changes to ADC, DAC modules. SDADC has only been tested in DMA + mode and does not support external TIMER triggers. This is a work in + progress. From Marc Recht. + - STM32 F3: Add PWM driver support for STMF37xx. The changes have been + tested successfuly for TIM4 and TIM17 (different IPs). From Marc + Recht. + - STM32 F4: Support oversampling by 8 for the STM32 F4. From David + Sidrane. + - STM32 F4: Added Timers 2-5 and control of SAI and I2S PLLs.

Add clocale header file. + - include/locale.h: Modify locale.h to add localeconv() and lconv + structure. From Alan Carvalho de Assis. + - libc/locale: Allows c++ code to compile with or without + CONFIG_LIBC_LOCALE and will generate a link error if + CONFIG_LIBC_LOCALE is not defined and setlocale is referenced. With + CONFIG_LIBC_LOCALE defined setlocale will act as if MB string is not + supported and return "C" for POSIX. C and "". From David Sidrane. + - libc/wchar: Add wcslen, wmemchr, wmemcmp, wmemcpy wmemset, btowc, + mbrtowc, mbtowc, wcscmp, wcscoll, and wmemmove to NuttX. From Alan + Carvalho de Assis. + - libc/wctype: Add functions wcrtomb, wcslcpy, wcsxfrm, wctob, wctomb, + wctype, localeconv, strcoll, strxfrm, swctype, towlower, towupper and + wcsftime. Add wctype.h; Move lib_wctype.c to libc/wctype. From Alan + Carvalho de Assis. + - include/ctype.h : Add isblank() macro to ctype.h. From Alan Carvalho + de Assis. + - lic/stdlib: Add strtof() and strtold() as simply a copy of strtod + with types and limits changed. + - sscanf(): Use strtof() instead of strtod() if a short floating point + value was requested. The should help performance with MCUs with + 32-bit FPU support with some additional code size. + - sscanf(): Add scansets to the scanf function. Enabled + CONFIG_LIBC_SCANSET option. From Aleksandr Vyhovanec. + - include/inttypes.h: Add architecture-specific inttypes.h. From Paul + A. Patience. + - C Library: Allow option to enable IP address conversions even when + the IP address family is not supported. + + * Build/Configuration System: + + - The Smoothie project needs to compile C++ inside config/boardname/src/ + to use with High Priority Interruption, then I modified the board + configs Makefile to support it. It works fine for the first time + compilation, but if we execute "touch config/boardname/src/Pin.cxx" + and execute "make" it will not detect that Pin.cxx was modified. I + think there is some other place I should modify, but I didn't find + it. From Alan Carvalho de Assis. + + * Tools: + + - tools/: Add tools/showsize.sh. + + * NSH: apps/nshlib: + + - NSH: dd command will show statistics. From Masayuki Ishikawa. + + * Applications: apps/system: + + - apps/system/sched_note: Extend to include additions to instumentation + for SMP. + - apps/system/sched_note: Add support for spinlock notes. + - apps/system/sched_note: Add support for new scheduler instrumentation. + + * Platforms: apps/platform: + + - ESP32 Core v2: Add platform support for the ESP32 core v2 board. + - Olimex STM32-p407: Add platform support for the Olimex STM32 P407. + + * Graphics: apps/graphics + + - graphics/traveler/tcledit and libwld: Add an X11 Tcl/Tk tool that can + be used to edit Traveler world files. + - Graphics: Remove all NX server taks. Instead, call boardctl() to the + NX server kernel thread. + + * Applications: apps/examples: + + - examples/buttons: Add a new buttons example that uses the button + character driver instead of the architecture buttons directly. From + Alan Carvalho de Assis. + - examples/cctype: Add an example to verify cctype functions. + - Remove RGMP example. + - examples/ostest: Extend the pthread cancellation test to exercise + pthread_cleanup_push() (and pthread_cleanup_pop() indirectly via + pthread_cancel() and pthread_exit(). + - examples/ostest: enhance pthread cancellation test some. + +Works-In-Progress: + + * IEEE802.14.5/6LowPAN. Hooks and framework for this effort were + introduced in NuttX-7.15. Work has continued on this effort on + forks from the main repositories, albeit with many interruptions. + The completion of this wireless feature will postponed until at + least NuttX-7.20. + +Bugfixes. Only the most critical bugfixes are listed here (see the +ChangeLog for the complete list of bugfixes and for additional, more +detailed bugfix information): + + * Core OS: + + - sched/semaphore: Within the OS, when a thread obtains a semaphore + count it must call sem_addholder() if CONFIG_PRIORITY_INHERITANCE is + enabled. If a count is available, then sem_wait() calls + sem_addholder(), otherwise it waited for the semaphore and called + sem_addholder() when it eventually received the count. This caused a + problem when the thread calling sem_wait() was very low priority. + When it received the count, there may be higher priority threads + "hogging" the CPU that prevent the lower priority task from running + and, as a result, the sem_addholder() may be delayed indefinitely. + The fix was to have sem_post() call sem_addholder() just before + restarting the thread waiting for the semaphore count. This problem + was noted by Benix Vincent who also suggested the solution. + - Many files: Make sure that priority inheritance is not enabled for + semaphores whose primary use is signaling (vs locking of resources) by + calling sem_setprotocol(). + - sched/semaphore: sem_trywait() no longer modifies the errno value + UNLESS an error occurs. This allows these functions to be used + internally without clobbering the errno value. From Freddie Chopin. + - sched/clock: Correct clock initialization. The correct range for the + month is 0-11 but is entered as 1-12 in the .config file. Add ranges + to START_YEAR, MONTH, and DAY in sched/Kconfig. + - sched/clock: Correct calculation for the case of Tickless mode with a + 32-bit timer. In that case, the calculation was returning millisecond + accuracy. That is not good when the timer accuracy is < 1 msec. From + Rajan Gill. + - Work Queue: When queuing new LP work, don't signal any threads if + they are all busy. From Heesub Shin. + - Work Queue: Signal sent from work_signal() may interrupt the low + priority worker thread that is already running. For example, the + worker thread that is waiting for a semaphore could be woken up by the + signal and break any synchronization assumption as a result. It also + does not make any sense to send signal if it is already running and + busy. This change fixes it. From Heesub Shin. + - Fix DEBUGASSERT() in group_signal.c. From Masayuki Ishikawa. + - Eliminate bad boardctl() commands: Remove all references to + BOARDIOC_PWMSETUP and board_pwm_setup(). Remove all references to + BOARDIOC_ADCSETUP and board_adc_setup(). Remove + BOARDIOC_CAN_INITIALIZE. CAN initialization is now done in the board + initialization logic just like every other device driver. + - pthreads: Fix an error in pthread_mutex_destroy(). An error could + occur while destroying a mutex after a pthread has been canceled while + holding the mutex. + - task_restart: Make sure new task starts with pre-emption disabled and + not in a critical section. + - Enter/leave Critical Sections. Major redeign to + enter/leave_critical_section logic to deal with the case where + interrupts are disabled only on the local CPU. In this case, some + rather complex spinlocks must be used to maintain the critical section + accross all CPUs. + - SMP Critical Sections: Fixes for the SMP case: (1) Change order for + SMP case in enter_critical_section: (1) Disable local interrupts + BEFORE taking spinlock and (2) If SMP is enabled, if any interrupt + handler calls enter_critical_section(), it should take the spinlock. + - SMP wdogs: Wdog timers use a tasking interface that to manipulate + wdogs, and a different interface in the timer interrupt handling logic + to manage wdog expirations. In the single CPU case, this is fine. + Since the tasking level code calls enter_critical_section, interrupts + are disabled and no conflicts can occur. But that may not be the case + in the SMP case. Most architectures do not permit disabling + interrupts on other CPUs so enter_critical_section must work + differently: Locks are required to protect code. this change adds + locking (via enter_critical section) to wdog expiration logic for the + the case if the SMP configuration. + - SMP vfork(): Fix a race condition in the SMP case. Existing logic + depended on the fact that the child would not run until waitpid was + called because the child had the same priority as the parent. BUT in + the SMP case that is not true... the child may run immediately on a + different CPU. + - SMP: This change adds a new internal interfaces and fixes a problem + with three APIs in the SMP configuration. The new internal interface + is sched_cpu_pause(tcb). This function will pause a CPU if the task + associated with 'tcb' is running on that CPU. This allows a different + CPU to modify that OS data stuctures associated with the CPU. When + the other CPU is resumed, those modifications can safely take place. + The three fixes are to handle cases in the SMP configuration where one + CPU does need to make modifications to TCB and data structures on a + task that could be running running on another CPU. Those three cases + are task_delete(), task_restart(), and execution of signal handlers. + In all three cases the solutions is basically the same: (1) Call + sched_cpu_pause(tcb) to pause the CPU on which the task is running, + (2) perform the necessary operations, then (3) call up_cpu_resume() to + restart the paused CPU. + - SMP: Add logic to avoid a deadlock condition when CPU1 is hung waiting + for g_cpu_irqlock with interrupts interrupts and CPU0 is waiting for + g_cpu_paused. + - SMP: Enforce this rule: Tasks which are normally restored when + sched_unlock() is called must remain pending (1) if we are in a + critical section, i.e., g_cpu_irqlock is locked , or (2) other CPUs + still have pre-emption disabled, i.e., g_cpu_schedlock is locked. In + those cases, the release of the pending tasks must be deferred until + those conditions are met. + + * File System/Block Drivers/MTD Drivers: + + - AT24XX EEPROM MTD driver: Added EEPROM timeout. Fromo Aleksandr + Vyhovanec. + - fs/procfs: Fix procfs status for SMP case. + + * Graphics/Graphic Drivers: + + - Fonts: Correct some default font IDs. From Pierre-Noel Bouteville. + + * Common Drivers: + + - usbhost/enumerate: Fix possible buffer overwrite. From Janne Rosberg. + - usbhost/composite: Fix compile; missing semicolons. From Jann Rosberg. + - syslog: Fixes required for file syslog output. From Max Kriegleder. + - SPI configuration: Fix Kconfig warning. This change moves the + ARCH_HAVE_SPI options outside the check for SPI. Those options don't + depend on SPI, and Kconfig files in arch/ enable them even if SPI + isn't enabled. Source the driver's Kconfig in drivers/Kconfig only + if support for the driver is enabled prevents us from defining these + ARCH_HAVE options in the driver's Kconfig. We should probably remove + the other checks in drivers/Kconfig and check if the drivers are + enabled only in their Kconfig. From Paul A. Patience. + - drivers/timer: Remove the timer driver TIOC_SETHANDLER IOCTL call. + This calls directly from the timer driver into application code. That + is non-standard, non-portable, and cannot be supported. Instead, add + timer driver hooks to support signal notification of timer + expiration. Signal notification logic added by Sebastien Lorquet. + - All timer lower half drivers. Port Sebastien's changes to all other + implementations of the timer lower half. + - USB MSC Device: Fix length of mode6 sense reply packet. From + Wolfgang Reinegger. + - USB Composite Host: Fix end offset in usbhost_copyinterface(). From + Janne Rosberg. + - USB CDC/ACM Host: Add CDC_SUBCLASS_ACM and CDC_PROTO_ATM to + supported class and proto. From Janne Rosberg. + - SSD1306: Fix errors in SPI mode configuration. From Gong Darcy. + - CDC/ACM Device Class: uart_ops_s portion of cdcacm will not be + initialized with correct functions if CONFIG_SERIAL_DMA is selected. + + * Networking/Network Drivers: + + - drivers/net/tun.c: Fix bug in TUN interface driver. From Max Nekludov. + + * ARMv7-A: + + - ARMv7-A SMP: Add SMP logic to signal handling. + + * ARMv7-M: + + - ARMv7-M: Fix double allocation of MPU region in mmu.h. + + * ARMv7-R: + + - ARMv7-R: Fix compilation error. This change fixes compilation errors + on MPU support for ARMv7-R. From Heesub Shin. + - ARMv7-R: fix invalid drbar handling. In ARMv7-R, [31:5] bits of DRBAR + is physical base address and other bits are reserved and SBZ. Thus, + there is no point in passing other than the base address. From Heesub + Shin. + - ARMv7-R: Remove the redundant update on SCTLR. mpu_control() is + invoking cp15_wrsctlr() around SCTLR update redundantly. From Heesub + Shin. + - ARMv7-R: Add new Kconfig entries for D/I-cache. Unlike in ARMv7-A/M, + Kconfig entries for data and instruction caches are currently missing + in ARMv7-R. This change adds those missing Kconfig entries. Actual + implmenetation for those functions will be added in the subsequent + patches. From Heesub Shin. + - ARMv7-R: Add cache handling functions. This change adds functions for + enabling and disabling d/i-caches which were missing for ARMv7-R. + From Heesub Shin. + - ARMv7-R: Fix typo in mpu support. s/ARMV7M/ARMV7R/g. From Heesub Shin. + - ARMv7-R: Fix CPSR corruption after exception handling. A sporadic + hang with consequent crash was observed when booting. It seemed to be + caused by the corrupted or wrong CPSR restored on return from + exception. NuttX restores the context using code like this: msr spsr, + r1. GCC translates this to: msr spsr_fc, r1. As a result, not all + SPSR fields are updated on exception return. This should be: msr + spsr_fsxc, r1. On some evaluation boards, spsr_svc may have totally + invalid value at power-on-reset. As it is not initialized at boot, the + code above may result in the corruption of cpsr and thus unexpected + behavior. From Heesub Shin. + - ARMv7-R: Fix to restore the Thumb flag in CPSR. Thumb flag in CPSR is + not restored back when the context switch occurs while executing thumb + instruction. From Heesub Shin. + + * Atmel SAM3/4 Drivers: + + - SAM3/4 UDP: Add delay between setting and clearing the endpoint RESET + bit in sam_ep_resume(). We need to add a delay between setting and + clearing the endpoint reset bit in SAM_UDP_RSTEP. Without the delay + the USB controller will (may?) not reset the endpoint. If the + endpoint is not being reset, the Data Toggle (DTGLE) bit will not to + be cleared which will cause the next transaction to fail if DTGLE is + 1. If that happens the host will time-out and reset the bus. Adding + this delay may also fix the USBMSC_STALL_RACEWAR in usbmsc_scsi.c, + however this has not been verified yet. From Wolfgang Reinegger. + - SAM3/4: Remove unused 'halted' flag from UDP driver. From Wolfgang + Reinegger. + - SAM3/4: Remove 'stalled' flag from the UDP driver. This flag is not + necessary because the state of the endpoint can be determined using + 'epstate' instead. From Wolfgang Reinegger. + + * Atmel SAM3/4 Boards: + + - SAM4S Xplained Pro: Configuration uses old, improper timer interface. + CONFIG_TIMER disabled in configuration. Remove obsolete timer + initialization logic. + + * Atmel SAMV7 Drivers: + + - SAMv7 USBDEVHS: A problem occurred with the SAMV7 USBDEVHS driver if + the USB cable is unplugged while a large amount of data is send over + an IN endpoint using DMA. If the USB cable is plugged in again after a + few seconds it is not possible to send data over this IN endpoint + again, all other endpoints work as expected. The problem occurs + because if the USB cable is unplugged while an DMA transfer is in + flight the transfer is canceled but the register SAM_USBHS_DEVDMACTRL + is left in an undefined state. The problem was fixed the problem by + resetting the register SAM_USBHS_DEVDMACTRL to a known state. + Additionally all pending interrupts are cleared. From Stefan Kolb. + - SAMV7 MCAN: Prevent Interrupt-Flooding of ACKE when not connected to + CAN-BUS. An Acknowledge-Error will occur every time no other CAN Node + acknowledges the message sent. This will also occur if the device is + not connected to the can-bus. The CAN-Standard declares, that the Chip + has to retry a given message as long as it is not sent successfully + (or it is not cancelled by the application). Every time the chip tries + to resend the message an Acknowledge-Error-Interrupt is generated. At + high baud rates this can lead in extremely high CPU load just for + handling the interrupts (and possibly the error handling in the + application). To prevent this Interrupt-Flooding we disable the ACKE + once it is seen as long we didn't transfer at least one message + successfully. From Frank Benkert. + - SAMV7 MCAN: Make delete_filter functions more robust. From Frank + Benkert. + + * Atmel SAMA5 Drivers: + + - SAMA5 PWM: Driver does not build when executing from SDRAM before + board frequencies are not constant. Rather, the bootloader configures + the clocking and we must derive the clocking from the MCK left by the + bootloader. This means lots more computations. This is untested on + initial change because I don't have a good PWM test setup right now. + + * Misoc LM32: + + - Misoc LM32: Corrects a bug that never occured in qemu on simulation or + real fpga. The error was that the r1 register was being modified out + of context switching and not restoring it. From Ramtin Amin + + * NXP Freescale i.MX6: + + - i.MX6 interrupt handling: Additional logic needed to handle nested + interrupts when an interrupt stack is used. Nesting can occur because + SGI interrupts are non-maskable. + + * NXP Freescale LPC43xx Drivers: + + - LPC43xx serial: Fix a typo in ioctl TIOCSRS485 ioctl. From Vytautas + Lukenskas. + - LPC43xx serial: Restore RS485 mode on serial port open (if RS485 is + enabled via menuconfig). From Vytautas Lukenskas. + - LPC43xx SD/MMC: Correct some definitions on SMMC control register in + lpc43_sdmmc.h. From Alan Carvalho de Assis. + - LPC43xx SD card: Correct pin configuration options needed for SD card + pins. From Alan Carvalho de Assis. + + * SiLabs EFM32: + + - EFM32: Fix a compilation error. From Pierre-noel Bouteville. + + * STMicro STM32 Drivers: + + - STM32 CHxN channels are always outputs. From Sebastien Lorquet. + - STM32 DAC: Fix shift value whenever there are is a DAC2 and, hence, + up to three interfaces. From Marc Recht. + - STM32 F1: Add TIM8 to STM32F103V pinmap. From Maciej Wjcik. + - STM32 F1: Fix for F1 RTC Clock, tested on F103. From Maciej Wjcik. + - STM32 F3: STM32F303xB and STM32F303xC chips have 4 ADCs. From Paul + A. Patience. + - STM32 F4: A new implementation of the STM32 F4 I2C bottom half. The + common I2C as this did not handled correctly in the current + implementation (see also https://github.com/PX4/NuttX/issues/54). The + changes almost exclusively affect the ISR. From Max Kriegleder. + - STM32 F4 OTGHS Host: If STM32F446 increase number of channels to + 16. From Janne Rosberg. + - STM32 F4: I think, that Size is (highest address+1 - Base address). + Base address has been removed and if address+count >= size we are + outside of the Flash. From David Sidrane. + - STM32 F4: Fix ADC compilation error when DMA isn't enabled. From Paul + A. Patience. + - STM32 F4: STM32F427 was rebooting. Over reached family. From David + Sidrane. + - STM32 F4: Added STM32F469 RAM size and deliberated STM32F446 size. + From David Sidrane. + - STM32 F4: Typo in stm32f76xxxx_pinmap.h edited online with + Bitbucket. From David Sidrane. + - STM32 F7: stm32_i2c.c Dejavu. Fixes a bug previously found in the + F4. From David Sidrane. + - STM32 F7: OTGDEV fixed typo. From David Sidrane. + - STM32 F7: Fix to SPI-Master driver. Without this the chip select + decoding feature will not work properly. From Michael Spahlinger. + - STM32 F7: STM32F7 SD/MMC driver depends on CONFIG_SDIO_DMA which is + only defined in stm32/Kconfig. Changed to CONFIG_STM32F7_SDMMC_DMA + and defined in stm32f7/Kconfig. + - STM32 F7: Fix some STM32F7 copy paste errors. From David Sidrane. + - STM32 L4: Complementary PWM outputs on STM32L4" (1) too many + parentheses when calculating max chan count and (2) channel 4 does not + have a complementary output. From Sebastien Lorquet. + - STM32 L4: Fix I2C devices RCC registers. From Sebastien Lorquet. + - STM32 L4: Enable and renaming for 32l4 UARTs 4 and 5. From Sebastien + Lorquet. + - STM32 L4: Change the way to configure quadrature encoder prescalers. + From Sebastien Lorquet. + - STM32 L4: Correct USART1/2 definitions. Use default mbed UART4 + settings. From Sebastien Lorquet. + + * STMicro STM32 Boards: + + - STM32F103 Minimum: Fix Timers 2 to 7 clock frequencies. From Alan + Carvalho de Assis. + - Nucleo-F303RE: Remove duplicate setting from board.h. From Marc + Recht. + - Nucleo F303RE: Various fixes to get the ADC configuration building + again after PR. Refresh all configurations. + - Nucleo L476RG: Add better selection of timer. + + * TI Tiva Boards: + + - DK-TM4C129x: Typo fix. From Wolfgang Reinegger. + + * Xtensa ESP32: + + - ESP32 core v2: Flush the UART TX buffer in the esp32 serial shutdown + routine. The ROM bootloader does not flush the FIFO before handing + over to user code, so some of this output is not currently seen when + the UART is reconfigured in early stages of startup. From Angus + Gratton. + - Xtensa ESP32: Corrects a problem with dispatching to signal + handlers: Cannot vector directly to the signal handling function as + in other ABIs under the Xtensa Window ABI. In that case, we need to + go through a tiny hook when performs the correct window call (call4) + otherwise registers will be scrambled in the signal handler. + + * Xtensa ESP32 Boards: + + - ESP32 core v2: Changes the openocd config file's default flash + voltage from 1.8V to 3.3V. This is not necessary right now, but may + save some hard-to-debug moments down the track (3.3V-only flash + running at 1.8V often half-works and does weird things...). From + Angus Gratton. + + * C Library/Header Files: + + - libc/stdio: Fixes sscanf() %sn where strlen(data) < n. From David + Sidrane. + - libc/stdio: Include wchar.h in lib_libvsprintf.c to fix compilation + error. From Alan Carvalho de Assis. + - include/sys/time.h: timersub macro modified per recommendations of + phreakuencies. + - include/ctype.h and cxx/cctype: Implement ctype.h functions as inline + if possible. cctype can then properly select namespace. + - include/: Fix a number of header files with mismatched 'extern C {' + and '}'. + - libc/unisted: Change brings strtol() and related functions more + conformant with POSIX. Corner cases like strtol(-2147483648, NULL, + 10) now pass clang -fsanitize=integer without warnings. From Juha + Niskanen. + - libc/unistd: sleep() was returning remaining nanoseconds (kind of), + instead the remaining seconds. From Eunbong Song. + - termios.h: Fix CRTSCTS define to include input and output flow. From + Lorenz Meier. + + * Build/Configuration System: + + - configs/*/defconfig: The buttons example was changed to archbuttons. + As a result all of the button configurations are broken and need some + renaming in the defconfig files. Noted by Frank Berkert. + - config/*/defconfgs: More fallout from name change of + apps/examples/buttons to archbuttons. + - configs: All QE encoder files. Last change made timer hard-coded to + 3. Make configurable. + - configs: Remove all traces of the no-longer existent ARCHBUTTONS + example. Remove all button configurations that depended on the + obsoleted ARCHBUTTON example. + - minnsh Configurations: Remove minnsh configurations and support + logic: up_getc() and lowinstream. This was an interesting exercise + to see just how small you could get NuttX, but otherwise it was not + useful: (1) the NSH code violated the OS interface layer by callup + up_getc() and up_putc() directly, and (2) while waiting for character + input, NSH would call up_getc() which would hog all of the CPU. Not a + reasonable solution other than as a proof of concept. + + * Application Build/Configuration System: + + - Make.defs: Using wrong link script if native window tool used with + Cygwin. + + * apps/platform: + + - ESP32 Core v2 Platform: Fix some naming that prevented building the + C++ support. + + * apps/nshlib: + + - NSH Library: nsh_getdirpath(), use snprint instead of sprintf to + avoid possibility of buffer overrun. Noted by Chung Hwan Kim. + + * apps/system: + + - Remove std_readline(). This called up_getc() and up_putc() directly, + violating the POSIX OS interface. + + * apps/netutils: + + - FTPD: Fixed bug that didn't free ftpd ressources on exit. From Pascal + Speck. + - NTP client: Fix missing left parenthesis.

From Pierre-Noel Bouteville. + - esp8266 update cosmetic and many bug fix. From Pierre-Noel Bouteville. + - FTPD: Fix bug un ftpd file or socket may be not closed. From + Pierre-Noel Bouteville. + + * apps/modbus: + + - Modbus Master is missing many files and doesn't compile at all. More + details in + https://groups.yahoo.com/neo/groups/nuttx/conversations/topics/13734. + From Vytautas Lukenskas. + + * apps/examples: + + - The examples/qencoder app was trying to init the encoder by a direct + call into the board, cheating in a local header to declare the + normally unavailable function prototype. From Sebastien Lorquet. + - apps/examples/timer: Should detach signal handler before exiting. + - examples/qencode: The examples/qencoder app was trying to init the + encoder by a direct call into the board, cheating in a local header to + declare the normally unavailable function prototype. From Sebastien + Lorquet. + - apps/examples/archbuttons: Removed becaue it violates OS interface + principles. + - examples/adc, pwm, can: Remove all usage of BOARDIOC_ADCTEST_SETUP, + BIOARDIOC_PWMSETUP. Remove BOARDIOC_CAN_INITIALIZE. CAN + initialization is now done in the board initialization logic just like + every other device driver. + - examples/ostest: Add some delays to the pthread cancellation test. + With deferred cancellation enabled, things happen more asynchronously. + +NuttX-7.20 Release Notes +------------------------ + +The 120th release of NuttX, Version 7.20, was made on March 8, 2017, +and is available for download from the Bitbucket.org website. Note +that release consists of two tarballs: nuttx-7.20.tar.gz and +apps-7.20.tar.gz. These are available from: + + https://bitbucket.org/nuttx/nuttx/downloads + https://bitbucket.org/nuttx/apps/downloads + +Both may be needed (see the top-level nuttx/README.txt file for build +information). + +Additional new features and extended functionality: + + * Core OS: + + - Kernel Modules: Module initializer may now return a symbol table. + - Modules: Extend the module interface so that we can access symbols + exported by the module. + - Shared Libraries: In the FLAT build mode, kernel modules may be + used to provide minimal shared library functionality. + - Modules/Shared Libraries: Add support for dependencies between + modules. + - Module Library: Add build a configuration logic for a shared module + library. + - Shared Libraries: Implement module based shared libraries for the + PROTECTED mode build. + - Interrupt handling: irq_attach() now includes an argument of type + xcpt_t that retained with the handler address. That argument is + then provided to the interrupt handler when the interrupt occurs. + The common parameter passing replaces the ad hoc parmater passing + implemented in current drivers. From Mark Schulte. + - Adapt many drivers to utilize the IRQ argument feature. + - All functions that used to return an xcpt_t old handler value, now + return an int error code. The oldhandler value is no longer useful + with the recent changes to the interrupt argument passing. Some of + the functions effected include board_button_irq(), arch_phy_irq(), + STM32 EXTI functions (Alarm, COMP, PVD), GPIO interrupt logic like + kinetis_pinirq(), stm32_gpiosetevent(), and others. + - IRQ subsystem: Add support for smaller interrupt tables as + described at + http://www.nuttx.org/doku.php?id=wiki:howtos:smallvectors .

Remove + CONFIG_SDIO_WIDTH_D1_ONLY. That should not be a global propertie, + but rather a capability/limitation of single slot when there may be + multiple slots. + - Removed dmasupported() method from the SDIO interface. That is now + a bit in the capability set. + - drivers/sensors: Add driver for the ST L3GD20 3 axis gyro. From + raiden00. + + * Atmel SAM3/4: + + - SAM3/4: Add support for ATSAM4S4C.

This is a collaborative + effort. Alan Carvalho de Assis did the initial prototype. + - C Library: Add setbuf() which is a trivial wrapper around setvbuf(). + - C library: Add swab(). + - C library: Add strtoimax and strtoumax. + - C library: Add ffs(), rindex(), an index(). Add strings.h. Move + strcasecmp, strncasecmp, bzero, bcmp, and bcopy to where they + belong in strings.h.h, not string.h. bzero, bcmp, and bcopy are + legacy functions; the contemporary counterparts should be used + instead. + - C library: Add fstatfs(). + - Update cwchar. Add cwctype. + + * Build/Configuration System: + + - Add configuration support for builds with Ubuntu under Windows 10. + + * Tools: + + - tools/noteinfo.c: A hack tool that I use to analyze some sched_note + output.

From Aleksandr Vyhovanec. + - apps/examples/sotest: Add a test for shared libraries. + - apps/examples/ostest: Add a test of setvbuf(). + - apps/examples/stat: Add a simple test for stat(), fstat(), + statfs(), and fstatfs(). + +Works-In-Progress: + + * IEEE802.14.5/6LowPAN. Hooks and framework for this effort were + introduced in NuttX-7.15. Work has continued on this effort on + forks from the main repositories, albeit with many interruptions. + The completion of this wireless feature will postponed until at + least NuttX-7.21. + +Bugfixes. Only the most critical bugfixes are listed here (see the +ChangeLog for the complete list of bugfixes and for additional, more +detailed bugfix information): + + * Core OS: + + - SMP: There were certain conditions that we must avoid by preventing + the release of the pending tasks while withn a critical section. + But this logic was incomplete; there was no logic to prevent other + CPUs from adding new, running tasks while on CPU is in a critical + section. This commit corrects this. This is matching logic in + sched_addreadytorun to avoid starting new tasks within the critical + section (unless the CPU is the holder of the lock). The holder of + the IRQ lock must be permitted to do whatever it needs to do. + - SMP: Make checks for CPU lock set more robust. There are certain + conditions early in initialization on during interrupt handling + where things need to be done a little differently. + - sched_cpulocked: Avoid use of spinlock. That has been reported to + cause a deadlock (2016-12-28). + - SMP: Fix a gap where we may try to make modifications to the task + lists without being in a critical sections. That permits + concurrent access to the tasks lists and many subtle problems. + This fix just remains in the critical section throughout the + operation (and possible until the task is restore in the event of a + context switch). Makes a big difference in stability. + - SMP: Fix an error in critical section logic when performing a + context switch from an interrupt handler. The g_cpu_irqset bit was + not being set for the CPU so other CPUs did not know about the + critical section. + - SMP Signals: Fix some SMP signal delivery logic. Was not handling + some critical sections correctly and was missing logic to signal + tasks running on other CPUs. + - SMP: Fix timer related issues: Round robin and sporadic + scheduling were only being performed for tasks running on the CPU + that processes the system timer interrupt. Similary, CPU load + measurements were only be processed for running on the CPU that + receives the sampling interrupt. + - sched_note: Fix spinlock instrumentation. From Masayuki Ishikawa. + - In all implementations of _exit(), use enter_critical_section() vs. + disabling local interrupts. + - sigtimedwait: When timer expires, up_unblock_task() is called. + This is okay in the single CPU case because interrupts are disable + in the timer interrupt handler. But it is insufficient in the SMP + case. enter_ and leave_critical_section() must be called in order + to manage spinlocks correctly. + - Fix a compile error: in sched_cpuload.c:Line136, the variables ts + and secs are not defined if CONFIG_CPULOAD_ONESHOT_ENTROPY = 0. + However, these variables are used regardless of + CONFIG_CPULOAD_ONESHOT_ENTROPY at lines~180:onwards. From Rajan Gill. + - CPU load: Correct computation of the nominal period to use when the + source is a oneshot timer. + - Cancellation points: Fix some backward logic in conditional + compilation. + - Remove an unused variable when calling sigwaitinfo() and + sigtimedwait(). From Masayuki Ishikawa. + + * File System/Block and MTD Drivers: + + - procfs: Correct to snprintf-related errors in fs_procfsproc.c. + Resolves issue #24. + - Add logic to VFS rename: If target of rename exists and is a + directory, then the source file should be moved 'under' the target + directory. POSIX also requires that if the target is a file, then + that old file must be deleted. + - Fix open() a block device with + CONFIG_DISABLE_PSEUDOFS_OPERATIONS=y. From Masayuki Ishikawa. + - File System: Don't build block driver proxy if PSEUDOFS_OPERATIONS + are disabled. + - sendfile(): Fix error introduced with commit + ff73be870e38959b0aaee5961dc47b4b58dc2d86. Noted by Maciej Wjcik. + + * Graphics/Graphic Drivers: + + - NxWM configurations. If using a 7-bit character set, then the + cursor character cannot be 137 (graphic block). Use 95 + (underscore) instead. + - NX server: Correct message queue names. Should not be at /dev, + but rather relative to /var/mqueue. + + * Common Drivers: + + - MMCSD_SDIO: Only wait for card ejected if card detection is + supported. From Alan Carvalho de Assis. + - Typos withim mtd/ with Macronix MX25L. In + NuttX/drivers/mtd/Make.defs letters X between M and 25 are + missing. Noted by Oleg Evseev. + - USBMSC: Always set LUN readonly flag. From Wolfgang Reinegger. + - drivers/lcd: ssd1306_configspi() must have global scope. + - MMC/SD SDIO: Some drivers need to start DMA before sending CMD24 + and some AFTER. From Alan Carvalho de Assis. + - drivers/tone.c: Handle configuration with multiple PWM channels. + This resolves issue #30: Audio Tone Generator and PWM Multiple + Output Channel options. + - drivers/tone.c: 50% duty needs to be expressed a a fixed precision + number. + - drivers/spi/Kconfig: There is too much SPI in the configuration + menu; SPI Driver Support menu is empty. From Maciej Wjcik. + - option to enable Memory Card debug output was hidden with SD cards + connected through SPI. From Maciej Wjcik. + - usbhost_cdcacm: fix tx outbuffer overflow and remove now invalid + assert. From Janne Rosberg. + + * Networking/Network Drivers: + + - Networking: Fixed some issues that prevented IPv6 from working with + IPv4 enabled. From Pascal Speck. + - Networking: fixed a nullptr-dereference on iob_clone. From Pascal + Speck. + - Ethernet: Need two work structures (minimum) in all Ethernet + drivers so that pending poll work is not lost when an interrupt + occurs. + + * ARMv7-R: + + - I found an issue inside the cp15_coherent_dcache function: The + "mcr CP15_BPIALLIS(r0)" should only be used with SMP + configurationa.

Noted by Oleg Evseev. + +NuttX-7.21 Release Notes +------------------------ + +The 121st release of NuttX, Version 7.21, was made on June 6, 2017, +and is available for download from the Bitbucket.org website. Note +that release consists of two tarballs: nuttx-7.21.tar.gz and +apps-7.21.tar.gz. These are available from: + + https://bitbucket.org/nuttx/nuttx/downloads + https://bitbucket.org/nuttx/apps/downloads + +Both may be needed (see the top-level nuttx/README.txt file for build +information). + +Additional new features and extended functionality: + + * Core OS: + + - pthread rwlocks: Add an implementation for read/write locks + (rwlocks) into the pthread library. These locks are writer + priority, such that if any writers come in they are given priority + for writing. From Mark Schulte. + - pthread robust mutexes: Implement robust mutex support: + pthread_mutex_lock() and trylock() will return EOWNERDEAD if the + mutex is locked by a thread that no longer exists. Add + pthread_mutex_consistent() to recover from this situation. Keep + list of all mutexes held by a thread in a list in the pthread's TCB. + When pthread exits or is cancelled, mutexes held by thread are + marked inconsistent and the highest priority thread waiting for the + mutex is awakened. There is a configuration option to (a) support + only robust mutexes, (b) support only traditional unsafe mutexes, + or (c) Support both unsafe and robust mutexes via + pthread_mutexattr_get/setrobust(). + - pthread cancellation points: Add logic to disable cancellation + points within the OS. This is useful when an internal OS function + that is NOT a cancellation point calls an OS function which is a + cancellation point. In that case, irrecoverable states may occur if + the cancellation is within the OS. From Juha Niskanen. + - clock: Add clock_resynchronize and use subseconds RTC. Add + clock_resynchronize for better synchronization of CLOCK_REALTIME and + CLOCK_MONOTONIC to match RTC after resume from low-power state. Add + up_rtc_getdatetime_with_subseconds under + CONFIG_ARCH_HAVE_RTC_SUBSECONDS to allow initializing (and + resynchronizing) system clock with subseconds accuracy RTC. From + Jussi Kivilinna. + - clock: Add new type ssystime_t for relative 64-bit ticks, change + ticks<->time conversion functions to use ssystime_t. From Jussi + Kivilinna. + - clock: Add testing for 32-bit overflow of 64-bit system timer. From + Jussi Kivilinna. + + * File Systems/Block and MTD Drivers + + - drivers/mtd/w25.c: Erase sector only if it is not in erased state. + From Jussi Kivilinna. + + * Graphics/Display Drivers: + + - drivers/lcd: Extend st7565 driver to include support for the + AQM_1248A. From Masayuki Ishikawa. + - drivers/lcd: Add driver for Nokia 5110 (Philips PCD8544). From Alan + Carvalho de Assis. + + * Networking/Network Drivers: + + - Extensive modifications to support wireless network (see below). + - TUN driver: Implement TAP (OSI layer 2) mode. Enable by setting the + IFF_TAP flag instead of the IFF_TUN flag in ifr_flags. From Thomas + Keh. + - Add user-space networking stack API (usrsock). User-space + networking stack API allows user-space daemon to provide TCP/IP + stack implementation for NuttX network. Main use for this is to + allow use and seamless integration of HW-provided TCP/IP stacks to + NuttX. For example, user-space daemon can translate /dev/usrsock + API requests to HW TCP/IP API requests while rest of the user-space + can access standard socket API, with socket descriptors that can be + used with NuttX system calls. From Jussi Kivilinna. + - net/: Network driver now retains Ethernet MAC address in a union so + that other link layer addresses may be used in a MULTILINK + environment. + + * Wireless Networking/Wireless Drivers: + + - BCM43362: Support for Broadcom's BCM43362 WiFi chip was contributed + by Simon Piriou as part of the port of the Particle Photon board. + Only station functionality is available at present. This work + includes not on the WiFi driver, but the support Particle Photon + board, the infrasture for IEEE 802.11 FullMAC networking including + the network device interface, WiFi configuration, AP scanning and + authentication and association with an AP. + - IEEE 802.11 networking tools and support. + - IEEE 802.15.4 MAC support. This is an effort that was started some + time back by Sebastien Lorquet (with some help from Matte Poppe). + Recently, Anthony Merlino has taken on this effort and has made + some significant progress. Using the Microchip MRF24J40 module with + the Mikroe Clicker2-STM32 board along with a PC-based IEEE 802.15.4 + sniffer, Anthonly has verified correct transmittion and receipt of + basic frames. + - Microchip MRF24J40: As mentioned above, this IEEE 802.15.4 radio + driver is now basically functional. + - IEEE 802.15.4 Network Driver: A driver that interfaces the NuttX + network with the IEEE 802.15.4 MAC has been developed but is still + incomplete and has not been verified. + - IEEE 802.15.4 Network Loopback Driver: A simple IEEE 802.15.4 MAC + loopback driver was developed. This driver allowed for parallel + development of the IEEE 802.15.4 MAC and 6LoWPAN. + - 6LoWPAN: The Contiki 6LoWPAN stack has been ported so that works + within the NuttX networking framework and interfaces with the new + IEEE 802.15.4 MAC via the network driver. Live testing with + IEEE 802.15.4 radios has not yet been done; all testing has used + the loopback driver. There are no known problems and the stack + is ready for additional testing. + - Add option to enable wireless debug output. + + * Other Common Device Drivers: + + - Add entropy pool and strong random number generator. Entropy pool + gathers environmental noise from device drivers, user-space, etc., + and returns good random numbers, suitable for cryptographic use. + Based on entropy pool design from *BSDs and uses BLAKE2Xs algorithm + for CSPRNG output. Patch also adds /dev/urandom support for using + entropy pool RNG and new 'getrandom' system call for getting + randomness without file-descriptor usage (thus avoiding file- + descriptor exhaustion attacks). The 'getrandom' interface is similar + as 'getentropy' and 'getrandom' available on OpenBSD and Linux + respectively. From Jussi Kivilinna. + - XBox One controller: Adds USB host driver support for the XBox One + controller. Currently only the latest version (XBox One X) + controller works. The older XBox One controllers do not enumerate + correctly. From Brian Webb. + - drivers/analog: Add basic COMP driver. From Mateusz Szafoni. + - drivers/analog: Add driver for the LTC1767L ADC.

From Timo + Voutilainen. + - drivers/usbmisc: Add driver for Fairchild FUSB301 USB type-C + controller. From Harri Luhtala. + - RTC: Add interface for check if RTC time has been set. New + interface allows checking if RTC time has been set. This allows to + application to detect if RTC has valid time (after reset) or should + application attempt to get real time by other means (for example, by + launching ntpclient or GPS). From Jussi Kivilinna. + - Buttons: Change return value of board_buttons() and the type of + btn_buttonset_t to uint32_t so that more than 8 buttons can be + supported. + - drivers/syslog: Use monotonic clock for timestamp when available. + From Jussi Kivilinna. + - SPI: Add an instance argument to the SPIDEV definitions. Thus, + instead of specifying a FLASH device, for example, as SPI_FLASH, you + would now use SPI_FLASH(0) where the "instance" argument now + distinguishes multiple FLASH devices on the same SPI bus. From + Sebastien Lorquet. + - IOBs: Move from net/iob to a better location in mm/iob where they + can be shared outside of the networking logic. Current also used + by IEEE 802.15.4 MAC and by syslog (when buffering enabled). + - syslog: Add option to buffer SYSLOG output to avoid interleaving. + Uses new shareable IOBs. Additional logic to assure that the the + write from the buffer is a single atomic write in normal debug + output. + - drivers/can: Move CAN subsystem to its own directory and put device + drivers there.

Included child scripts will run with the parents settings and + changes made in the child script will effect the parent on return. + Use 'set -e' to enable and 'set +e' to disable (ignore) the exit + condition on commands. The default is -e. Errors cause script to + exit. Use 'set -x' to enable and 'set +x' to disable (silence) + printing a trace of the script commands as they are ececuted. The + default is +x. No printing of a trace of script commands as they are + executed. From David Sidrane. + - Print expanded variables if -x. From David Sidrane. + - ifconfig command: Extend ifconfig to support 6LoWPAN. Adapt to + some changes in configuration variable usage. + - Network initialization: If IEEE802.11 selected use wlan0 instead of + eth0 for network device name. + - Network initialization: NSH now has configuration options to select + the wireless properties. It builds the configuration structure and + passes this to wpa_driver_wext_associate() so that it will set the + network as configured. + - Network initialization: Add a new option CONFIG_NSH_NETLOCAL that + will suppress some built in operations and will support manual + configuration of a wireless network through command line tools. + + * Examples/Tests: apps/examples: + + - examples/xbc_text: Adds a test program for the XBox One controller + driver. From Brian Webb. + - examples/ostest: Add a test of robust mutexes. + - examples/ostest: Add tests for pthread_rwlock. Adding tests to be + used to verify the pthread_rwlock lock works.

From Juha Niskanen. + + * Network Utilities: apps/netutils: + + - netutils/netlib: Add IEEE 802.11 wireless IOCTL wrappers. + - netutils/netlib: Add a helper function to convert a string to a + 6LoWPAN node address. + - netlib and NSH: Add logic to get/set the IEEE802.15.4 PAN ID. + - netutils/dhcpc: Make the network device name a configuration + option. Was hardcoded to eth0 but may, instead, need to be wlan0. + - netutils/dhcpc: Remove hard-coded interface device. Now passed as + a parameter to dhcpc_open(). From Sebastien Lorquet. + + * Wireless Utilities: apps/wireless: + + - wireless/wapi: Port of Wapi wireless services. The original + depended on features not supported by NuttX: Removed logic that + depends on Linux netlink. Removed functionality that depended on + the Linux procfs: This includes only 1) listing of available + interfaces and 2) listing of all routes. + - wireless/wapi: Create command line Wapi application based on + Wapi sample code. + - wireless/wapi: wpa_driver_wext_associate() now accepts a + configuration parameter that can be used to specify the wireless + properties. + - wireless/wapi: Add basic wapi_event_stream_extract implementation. + From Simon Piriou. + - wireless/ieee802154: Add iwpan and i8sak tools. iwpan is similar + in concept to wapi. From Anthony Merlino (i8sak was originally + by Sebastien Lorquet). + - wireless/ieee802154/libmac: IEEE 802.15.4 MAC library. + - wireless/wext: Add drivers_wext from the WPA supplicant; Integrate + into NSH. From Simon Piriou. + + * System Utilities (apps/system) + + - apps/system/dhcpc: Add a command to renew or establish a lease on an + IPv4 address. + - apps/system/ntpc: Add a command to start or stop the NTPC daemon. + - apps/system/ramtest: Make stacksize and priority conigurable. + + * Platform-Specific Support (apps/platform) + + - apps/platform: Create gnu/ subdirectory that contains the one and + only GNU C++ initialization function. Remove all other C++ + initialization functions. + +Bugfixes. Only the most critical bugfixes are listed here (see the +ChangeLog for the complete list of bugfixes and for additional, more +detailed bugfix information): + + * Core OS: + + - Priority inheritance: When CONFIG_SEM_PREALLOCHOLDERS==0, there is + only a single, hard-allocated holder structure. This is problem + because in sem_wait() the holder is released, but needs to remain in + the holder container until sem_restorebaseprio() is called. The call + to sem_restorebaseprio() must be one of the last things the + sem_wait() does because it can cause the task to be suspended. If in + sem_wait(), a new task gets the semaphore count then it will fail to + allocate the holder and will not participate in priority + inheritance. This fix is to add two hard-allocated holders in the + sem_t structure: One of the old holder and one for the new holder. + - Priority inheritance: sem_holder sem_findholder missing + inintalization of pholder. sem_findholder would fail and code + optimization covered this up. From David Sidrane. + - Partial Fix priority inheritance CONFIG_SEM_PREALLOCHOLDERS=0. From + David Sidrane. + - Priority inheritance: sem_boostholderprio prevent overrun of + pend_reprios. The second case rtcb->sched_priority <= + htcb->sched_priority did not check if there is sufficient space in + the pend_reprios array.

From David Sidrane. + - Priority inheritance: Fixes improper restoration of base_priority in + the case of CONFIG_SEM_PREALLOCHOLDERS=0. The call to + sem_restorebaseprio_task context switches in the + sem_foreachholder(sem, sem_restoreholderprioB, stcb); call prior to + releasing the holder. So the running task is left as a holder as is + the started task. Leaving both slots filled thus failing to perform + the boost/or restoration on the correct tcb. This PR fixes this by + releasing the running task slot prior to reprioritization that can + lead to the context switch. To faclitate this, the interface to + sem_restorebaseprio needed to take the tcb from the holder prior to + the holder being freed. In the failure case where sched_verifytcb + fails it added the overhead of looking up the holder. There is also + the additional thunking on the foreach to get from holer to + holder->tcb. An alternate approach could be to leve the interface + the same and allocate a holder on the stack of sem_restoreholderprioB + copy the sem's holder to it, free it as is done in this pr and + then pass that address sem_restoreholderprio as the holder.

From Masayuki Ishikawa. + - binfmt/elf: Fix offset value when calling elf_read() in + elf_sectname(). From Masayuki Ishikawa. + - There can be a failure in IOB allocation to some asynchronous + behavior caused by the use of sem_post(). Consider this scenario: + (1) Task A holds an IOB. There are no further IOBs. The value of + semcount is zero. Task B calls iob_alloc(). Since there are not + IOBs, it calls sem_wait(). The value of semcount is now -1. (2) + Task A frees the IOB. iob_free() adds the IOB to the free list and + calls sem_post() this makes Task B ready to run and sets semcount to + zero NOT 1. There is one IOB in the free list and semcount is zero. + When Task B wakes up it would increment the sem_count back to the + correct value. (3) But an interrupt or another task runs occurs + before Task B executes. The interrupt or other tak takes the IOB off + of the free list and decrements the semcount. But since semcount is + then < 0, this causes the assertion because that is an invalid state + in the interrupt handler. So I think that the root cause is that + there the asynchrony between incrementing the semcount. This change + separates the list of IOBs: Currently there is only a free list of + IOBs. The problem, I believe, is because of asynchronies due + sem_post() post cause the semcount and the list content to become out + of sync. This change adds a new 'committed' list: When there is a + task waiting for an IOB, it will go into the committed list rather + than the free list before the semaphore is posted. On the waiting + side, when awakened from the semaphore wait, it will expect to find + its IOB in the committed list, rather than free list. In this way, + the content of the free list and the value of the semaphore count + always remain in sync. + - binfmt: Fix .dtor memory allocation.

From David + Sidrane. + - STM32 CAN: I had the problem that the transmit FIFO size (= actual + elements in FIFO) was slowly increasing over time, and was full after + a few hours. The reason was that the code hit the line + "canerr("ERROR: No available mailbox\n");" in stm32_cansend, so + can_xmit thinks it has sent the packet to the hardware, but actually + has not. Therefore the transmit interrupt never happens which would + call can_txdone, and so the size of the FIFO size does not decrease. + The reason why the code actually hit the mentioned line above, is + because stm32can_txready uses a different (incomplete) condition than + stm32can_send to determine if the mailbox can be used for sending, + and thus can_xmit forwards the packet to stm32can_send. + stm32can_txready considered mailboxes OK for sending if the mailbox + was empty, but did not consider that mailboxes may not yet be used if + the request completed bit is set - stm32can_txinterrupt has to + process these mailboxes first. Note that I have also modified + stm32can_txinterrupt - I removed the if condition, because the CAN + controller retries to send the packet until it succeeds. Also if the + condition would not evaluate to true, can_txdone would not be called + and the FIFO size would not decrease also. From Lederhilger Martin. + - STM32 Serial: Fix freezing serial port.

Note +that release consists of two tarballs: nuttx-7.22.tar.gz and +apps-7.22.tar.gz. These are available from: + + https://bitbucket.org/nuttx/nuttx/downloads + https://bitbucket.org/nuttx/apps/downloads + +Both may be needed (see the top-level nuttx/README.txt file for build +information). + +Additional new features and extended functionality: + + * Core OS: + + - pthreads: Move functions from sched/pthreads to libc/pthreads. These + functions just coordinate other OS interface calls but are not a + fundamental OS interfaces and, hence, do not belong within the OS: + pthread_yield(), pthread_once(), pthread_cond_init(), + pthread_cond_destroy(), pthread_barrier_init(), + pthread_barrier_destroy(), and pthread_barrier_wait(). + - Add power-related debug output. + + * File Systems/Block and MTD Drivers + + - RAMTRON: Add support for splitting block writes in chunks. Some + Re-RAMs like MB85AS4MT have a write buffer size limitation. From + Boris Astardzhiev. + - MTD: Add driver for Macronix QuadSPI flash memory. From Simon Piriou. + + * Graphics/Display Drivers: + + - SSD1306 LCD Driver: (1) Separate lcd_dev_s setup to separate object. + g_oleddev takes 1 KiB because framebuffer and was allocated to .data + section because of lcd_dev_s function pointer setup. Move lcd_dev_s + setup out, so that g_oleddev goes to .bss and avoid wasting ROM. (2) + Fix memory corruption caused by ssd1306_getrun(). ssd1306_getrun was + writing one extra byte (with value 0) past target buffer when pixlen + is multiple of 8. When pixlen was not multiple of 8, last byte of + buffer was fully cleared, instead of modifying only the (pixlen % 8) + bits of last byte. (3) Add support for board power control. + ThingseeOne has regulator for controlling display power on/off. Patch + adds support for board based power control to SSD1306 driver. (4) Add + DD-12864WO-4A/SSD1309 support to SSD1306 driver.

From + Masayuki Ishikawa. + - TUN Driver: Add definitions that will permit TUN-only networking. + - Socket I/F: Created a socket interface used to provide socket support. + Each address family has an interface that describes how to perform + socket operations on that address family. Currently only a couple of + methods are defined in the socket interface call table + - Remove CONFIG_NET_MULTILINK. This increases code size by a little, + but greatly reduces the complexity of the network code. + - Network procfs: Add support for routing tables at proc/net/route. + - Network procfs: Add support for network procfs statistics for the + PF_IEEE802154 address family. + - Network Driver Backlog: Remove driver based backlog support. This + affects the entire network, but is used by only one driver. The only + supported RX backlog is now via common read-ahead buffering. + + * Wireless Networking/Wireless Drivers: + + - IEEE 802.15.4 MAC / MRF24J60 Driver: Extensive updates for + association/beacon-enabled networks. From Anthony Merlino. + - IEEE 802.15.4 MAC / MRF24J60 Driver: Hook in setdevmode from newly + added radio attribute setting. From Anthony Merlino. + - IEEE 802.15.4 MAC: Supports get request for coordinator address. From + Anthony Merlino. + - IEEE 802.15.4 MAC: Notify radio layer of changes in devmode. From + Anthony Merlino. + - IEEE 802.15.4: Add special attribute that can be used to perform a + regdump of the radio. From Anthony Merlino. + - IEEE 802.15.4 loopback driver: Better simulation addressing: short + and extended addresses, panid, and IP address conversion. + - IEEE 802.15.4 Network Driver: Add logic to setup the network mask, + update the MAC-based IPv6 addressing when the network is brought up. + The idea is that addressing changes are supposed to occur only while + the network is down but won't take effect until the network is up + again. + - PktRadio: Add an infrastructure to support networking on generic + (non-IEEE 802.15.4) packet radios. + - PktRadio Loopback Driver: Add a PktRadio loopback network driver to + testing testing with 6LoWPAN and PktRadios on the simulator. + - Spirit Network Driver: The Spirit1 radio (SPSGRF-915) is the first + generic PktRadio Network driver. Based on STMicros STack packets + with 8-bit addressing. We need to use the STack packets in order to + provide the source address and automatic ACKing. + - Network procfs: Fix so that PktRadio address are shown correctly. + - Networking: Add support for some packet radio IOCTL commands. + - 6LoWPAN: Added handling for TCP and ICMPv6 packets. + - 6LoWPAN: Add configurable support for 6LoWPAN star topology. With + this change, the endpoints which are the 'points' of the star will + forward all traffic to the coordinator. The coordinator is assumed to + be the 'hub' of the star. This function also used IPv6 forwarding. + - 6LoWPAN: The original, Contiki-based design used only a single buffer + for reassemblying larger packets. This could be a problem issue for + hub configurations which really need the capability concurrently + reassemble multiple incoming streams concurrently. These was also a + design issue in that the reassembly buffer could be corrupted by + outgoing packets. The design was extended to support multiple + reassembly buffers, each associated with the reassembly tag and source + address. This assures that there can be be no corruption of the + reassembly once it has started. + - 6LoWPAN PktRadio: Now radio agnostic. All IEEE 802.15.4 dependencies + have been removed or isolated so that 6LoWPAN can be used with any + kind of packet radio. This involved things like: (1) generalizing + the representation of radio MAC meta-data, (2) changes to handle + variable-length radio addresses, (3) removal of all explicit IEEE + 802.15.4 types, references, and interfaces, (4) a new radio driver + interface to return 'capabilities' of the drvier. + - ICMPv6: Update so that ICMPv6 can be used with 6LoWPAN. + - IPv6 Neighbor: Update table format to support IEEE 802.15.4 MAC + addresses. + - PF_IEEE802154 Address Family: Add support for the PF_IEEE802154 + address family socket type. This socket is similar to the PF_PACKET, + "raw" packet address family except that: (1) it supports only + SOCK_DRAM, not SOCK_RAW, and (2) works only with IEEE 802.15.4 + MAC-based radios. This address family permits simple access to IEEE + 802.15.4 IOCTLs and frame-level network transfers. + + * Other Common Device Drivers: + + - Dynamically configurable USB composite devices: We developed a huge + Changeset over a year ago to make USB Composite configuration + dynamical and be able to instantiate the CDC/ACM multiple times inside + this device. We use this feature to switch between one in typical USB MSC + CDC/ACM configuration and up to three CDCACMs dynamically. + I've changed the interface for some USB-Functions to receive also the + dynamic configuration. From Frank Benkert. + - Franks' change remained on a branch until all issues were resolved. + the current version in Master is complete and ready for use. + - power: battery_charger: Add ioctl for charging input current.

Made attach + and detach functions optional. As they do not make sense for a bus + powered device. From David Sidrane. + - Kinetis SPI driver: From David Sidrane. + - Kinetis: I2C driver added I2C3, reference counting and reset. + Refactored the driver to support reference counting and reset added + I2C3. From David Sidrane. + - Kinetis RTC: Implementation of the alarm read function. + + * NXP Freescale Kinetis Boards: + + - configs/teensy-3.x USB: Define USBOTG-FS Read from FLASH access in + board config. Allow the board config to define the USBOTG-FS to have + Read access to FLASH. From David Sidrane. + - configs/teensy-3.x: Removed call to khci_usbattach. The call is not + need by the driver if CONFIG_USBDEV_BUSPOWERED=y. On a USB powered device if we are running we are attached. From David Sidrane. + - freedom-k66f: Use SPI driver. Initalize SPI1 on connector J6. No + real use, as of yet. From David Sidrane. + + * NXP Freescale LPC43xx: + + - LPC43xx: Modify up_allocate_(k)heap() to support PROTECTED mode.

From Masayuki Ishikawa. + + * STMicro STM32: + + - STM32 L4: Add support for the STM32L475 family. + - STM32 L4 RCC: Enable ADC clock source. From Juha Niskanen. + - STM32: Allow clock frequencies > 168 Mhz on stm32f427/429. We need + to enable the power overdrive for this case. This change allows the + required bits to be set in proper sequence. It also modifies the + local register access operations to allow more than 16-bit registers. + From Sebastien Lorquet . + - STM32 F4: Add support for STM32F433RC. From Alan Carvalho de Assis. + - STM32 F7: Add new configuration option for enabling flash ART + Accelerator and flash prefetcher.

From Mateusz Szafoni. + - STM32 DAC: Support external triggering for DMA transfer. From Mateusz + Szafoni. + - STM32 L1 TIM: Add base address for TIM11. From Juha Niskanen. + - STM32 F4 FLASH: Enable/disable the flash write protection on any + sector. I have verified it to work on the STM32 F427. From Sebastien + Lorquet. + - STM32 F4 Clocking: To use an external oscillator module (not just a + crystal) with the STM32F4, one needs to enable the HSEBYP bit in the + RCC_CR register. This change allows an integrator to define + STM32_RCC_CR_HSEBYP in their board.h file if they want this + configuration. From Jeff. + - STM32 F4 USB: I'm working on bringing up USB full-speed support on + STM32F405. My board does not include a USB power switch, VBus + sensing, over current detection, or ID pin. This commit add a + configSTM32_OTGFS_VBUS_ CONTROL which lets us selectively disable + VBus sensing and control. I also sneaked in a change to disable the + configgpio call for the ID pin, which is only used in OTG mode which + isn't supported yet. The only pins that need to be initialized should + be OTGFS_DP and OTGFS_DM. From Jeff. + - STM32 FLASH: Add CONFIG_STM32_STM32F469 support. From David Sidrane. + - STM32 COMP: Add default INM configuration and some missing COMP + 1,3,5,7 code. From Mateusz Szafoni. + - STM32 F33: Add missing SYSCFG CFGR3 definitions. From Mateusz Szafoni. + - STM32 L4 Serial: Allow configuring Rx DMA buffer size. From Juha + Niskanen. + - STM32 L4 COMP: Input minus pin extended selection. From Juha Niskanen. + - STM32 L4 COMP: Bind to upper half comp driver. From Pekka Ervasti. + - STM32 L4 DAC: Port from STM32. Add ADC register definitions. From + Juha Niskanen. + - STM32 L4 DAC: Add option for routing DAC output to ADC. Actually + write something to the DAC DMA buffer. From Juha Niskanen. + - STM32 L4 DAC: Separate DMA buffer configuration for channels. From + Juha Niskanen. + - STM32 L4 ADC: Implement peripheral. From Juha Niskanen. + - STM32 F7: Definitions for I2C4, SDMMC2. Adapted RAM start / size to + internal SRAM. From Titus von Boxberg. + - STM32 F7 I2C4: I2C4_SDA can also be on GPIO PB7. From Titus von + Boxberg. + - STM32 F7 LTDC: Option for DSI output, inconsistency: the stm32f746 + does not feature a DSI interface. compilable with LTDC_INTERFACE and + LTDC_USE_DSI. From Titus von Boxberg. + - STM32 F7 Clocking: Added functions for DSI clock source selection. + From Titus von Boxberg. + - STM32 F7 Clocking: Enable APB2 DSI clock. From Titus von Boxberg. + - STM32 F7 LTDC: No board specific dithering values used; corrected + dithering init. Corrected LIPOS/LIPCR calculation. Change only + polarity bits in LTDC_GCR. From Titus von Boxberg. + - STM32 F7 Reset: Added function for reset. From Titus von Boxberg. + - STM32 F7 DMA: DMA add dcache alignment check in stm32_dmacapable. In + the case dcache write-buffed mode is used (not write-through) buffer + alignment is required for DMA transfers because a) + arch_invalidate_dcache could lose buffered writes data and b) + arch_flush_dcache could corrupt adjacent memory if the maddr and the + mend+1, the next next address are not on ARMV7M_DCACHE_LINESIZE + boundaries. From David Sidrane. + - STM32 F7 SDMMC: SDMMC remove widebus limitation on DMA. There is no + documantation for the STM32F7 that limits DMA on 1 bit vrs 4 bit + mode. From David Sidrane. + - STM32 F7 SDMMC: SDMMC add dcache alignment check in + dma{recv|send}setup. In the case where CONFIG_SDIO_PREFLIGHT is not + used. + - STM32 F7 RTC: Port Boris Astardzhiev's RTC change for STM32L4 to + STM32F7. + + * STMicro STM32 Boards: + + - STM32F103-Minimum: Add GPIO device driver example. From Alan + Carvalho de Assis. + - STM32F103-Minimum: Add small hello example for STM32F103-Minimum + board. From Alan Carvalho de Assis. + - STM32F103-Minimum: Add support for SmartFS on Winbond W25 SPI NOR + Flash. From Alan Carvalho de Assis. + - STM32F103-Minimum: (1) Enable CONFIG_MTD_PARTITION in Kconfig if flash + partition is enabled and (2) Update the README.txt file with info + needed to get SmartFS working. From Alan Carvalho de Assis. + - Nucleo-F334R8: Add HRTIM initialization. From Mateusz Szafoni. + - Nucleo-F334R8: UART2 is default serial port (STLINK Virtual Port). + From Mateusz Szafoni. + - Clicker2-STM32: Add a configuration that was used with the MRF24J60 + for 6loWPAN testing. + - Clicker2-STM32: Allow both IEEE 802.15.4 MAC character and network + devices to be registered. + - Clicker2-STM32: Add configurations to support the endpoint and hub + roles in a star topology. + - Clicker2-STM32: Add support for per-function-call stack checking. + From Anthony Merlino. + - Clicker2-STM32: Configure EDBG SPI CS just to make that it is + disabled. + - STM32F4 Discovery: Add logic to register the button driver and the + user led driver if so configured. From Jan Pobrislo. + - STM32F4-Discovery: Add a configuration for testing libc++. From Alan + Carvalho de Assis. + - B-L475E-IOT01A: Add support for the STMicro B-L475E-IOT01A board. + From Simon Piriou. + - B-L475E-IOT01A: Add support for the SPSRGF/Spirit1 radio module. Add + a configuration for testing sprit radio. + - B-L475E-IOT01A: Add configurations to support a star topology. + - B-L475E-IOT01A: Add basic support for external Macronix QuadSPI flash + memory. From Simon Piriou. + - B-L475E-IOT01A: Enable UDP broadcast test in the spirit-starhub + configuration. + - STM32F334-DISCO: Add STM32F334-DISCO basic support. From Mateusz + Szafoni. + - STM32F746-Disco: Add ADC3 support. From Ivan Ucherdzhiev. + - STM32L476-Disco: Add a knsh configuration that may be used to test + the PROTECTED build mode. + - STM32F769I-DISCO: Initial port to STM32F769I-DISCO. From Titus von + Boxberg. + + * C Library/Header Files: + + - Move TUN ioctl command to include/nuttx/net/ioctl.h so that it will + always be unique. + - Math Library: Port gamma() and lgamma() from FreeBSD to NuttX. From + Alan Carvalho de Assis. + - C++: Compilation with recent C++ compiler needs an overloaded delete + operator that includes a size_t size argument. New sized delete + operators are only for C++14 and above. + + * Build/Configuration System: + + - Initial clang compile. From Goran Mekic. + - Add CLANG definitions in Kconfig and Toolchain.defs. + - drivers/wireless/ieee802154: Moved radios to individual + sub-directories. From Anthony Merlino. + - Makefile.unix: Add savedefconfig target. From Gwenhael Goavec-Merou. + - Add Gwenhael's change to Makefile.win and update README.txt to + described the new make target. + - All defconfig files are now in the compressed format created with + 'make savedefconfig.' The original .config file can be reconstituted + using 'make olddefconfig.' + - Build System: It is no longer necessary to have a unique Make.defs + file for each configuration. A board may share a common Make.defs + file in the scripts directory. Duplicate Make.defs files removed; + common Make.defs file moved to the scripts/ sub-directory for each + board. + - Networking: Move INET socket interface out of net/sockets to its own + directory net/inet. + + * Tools: + + - testbuild.sh: Added -x to fail build on errors for continous + integration (CI). On CI we want to know ASAP of a failure. From + David Sidrane. + - Improve configure.sh behavior: (1) enable to call from top directory. + (2) enable to designate direct path for config. (3) install .gdbinit + if the target has. From Hidetaka Takano. + - Update tools/configure.c to same functionality as configure.sh. Add + an array of optional file names. Currently, .gdbinit is the only + optional file but other things like IDE-specific project files might + need to be copied as well. + - tools/configure.sh will now copy Eclipse project files if they are + present in the board directory file. + - Update configure.sh, configure.bat, configure.c: With compressed + format, part of the installation requires that we run 'make + olddefconfig' to restore the uncompressed defconfig format. Also, + while I was at it, I also added options to select host platform on + configure command line. + - tools/refresh.sh: Now runs make savedefconfig before copying the new + defconfig file in place; Also, added a new option --defaults. Since + the number of defaults that you now have to answer is so large, the + option lets you just accept the default values. So it works just like + --silent but still prompts you for the decision to save or discard the + new defconfig file. + - tools/refresh.sh: Update so that it can find the Make.defs file in + the new location. + + * NSH: apps/nshlib: + + - NSH Library: Add a Telnetd command. This is needed when network + initialization is deferred. In that case, telnet daemon cannot be + started until the network is finally initialized. The telnetd command + was added just for that case: So that the telnet daemon can be + started from the NSH command line after the network is configured. + - NSH Library: Misc changes needed for PktRadio support. + - NSH Library: Extend ifconfig command so that it can set variable + length packet radio addresss. + - NSH Library: Update addroute and delroute command. The would support either + IPv4 or IPv6, but not both. Allow expression of the netmask in IPv4 CIDR or + IPv6 slash notation. This really reduces the pain of using the commands, + especially for IPv6. + - NSH Library: Add a route command that will dump the content of routing table. + + * Examples/Tests: apps/examples: + + - examples/udp: Add configurable network device name; Add option to + suppress network initialization which is not needed if started by NSH + or for 6LoWPAN. + - examples/udp: Fix registration as a built-in program; Change some + naming to make room for a second target. Current one endpoint is the + target and one is the host. This will (eventually) allow two targets + to be both endpoints of the test. Change build so that both server + and client can be on a target, rather than one on the target one on + the host PC. Server IP address may not be provided on the command line. + - examples/udp: Port numbers need to be configurable to work with + 6LoWPAN. Need to bind the client socket to a port number. This was + not required before so is a apparently a change in the UDP packet + dispatch logic. + - examples/udp: Enable testing with the broadcast address. + - examples/nettest: Support target boards on both ends of the test. + Separate out network initialization so that it may be used by both a + target server and a target client. Fix client/server naming + confusion; Add command line option to select the server address on the + target. Add support for both enpoints on target boards vs. one on a + target and one on the host PC. + - examples/nettest: The send buffer size is now a configuration option. + - examples/nettest: Loopback option should be available in Kconfig for + PktRadio. + - examples/keypadtest: REMOVED and warehoused in the Obsoleted + repository. This was just a bad clone of apps/examples/hidkbd for a + keypad driver that was removed years ago. It also uses illegal + function calls into the OS. So it has no purpse: It is redundant, it + uses illegal interfaces, and is a test for non-existent code. + - examples/ipforward: Add an IP forwarding example using only TUN + devices. Test extended to test forwarding of ICMPv6 multicast messages. + - Implement powermonitor example for ltc4151 current and voltage + monitor. From Giorgio Gro. + - examples/pf_ieee802154: Add for testing PF_IEEE802154 sockets. Add + PANID to command line options; Cannot bind to address zero... There is + no counterpart to INADDR_ANY for these radios (not now at least). + - examples/dac: Add DAC example. From Juha Niskanen. + + * Network Utilities: apps/netutils: + + - netutils/telnetc: This a port of libtelnet to NuttX. + - netutils/telnetd and users of telnetd: Add support for IPv6. + - netutils/thttpd: Remove the netstats demo. This depends on an + illegal function call and cannot be supported. That example could be + replaced with logic that uses the procfs network entries as was done + for NSH which had the same issue. But I am too lazy to implement that. + - netutils/netlib: Add support for PktRadio IOCTL commands. + - netutils/netlib: Add a helper to decode short addresses. + + * Wireless Utilities: apps/wireless: + + - wireless/ieee802154/i8sak: Rewrote i8sak to be test CLI for IEEE + 802.15.4 MAC layer. From Anthony Merlino. + - wireless/ieee802154/i8sak: Updates to i8sak for + association/beacon-enabled changes to IEEE 802.15.4. From Anthony + Merlino. + - wireless/ieee802154/i8sak: Add option to make it easy to send large + frame for testing purposes. From Anthony Merlino. + - wireless/ieee802154/i8sak: Add scan command. From Anthony Merlino. + - wireless/ieee802154/i8sak: Add coordinfo command allowing you to + poll various attributes related to the coordinator. From Anthony + Merlino. + - wireless/ieee802154/i8sak: Add a option to retry on failures to the + assoc command (usually meaning tht the coordinator is not yet up). + - iwireless/ieee802154/8sak: Add reset command to reset the MAC layer. + Adds option to assoc command -t to specify how long to wait for a + response from the Coordinator. From Anthony Merlino. + - ieee802154/i8sak: Adds command to trigger regdump of radio. From + Anthony Merlino. + + * System Utilities (apps/system) + + - apps/system/composite: Update to apps/system/composite assocated with + big changes to the composite device logic. From Frank Benkert. + - apps/system/composite: Remove CDC/ACM and MSC configuration logic. + This belongs in the OS composite initialization. Add and argument so + that you can select the USB composite configuration to be attached. + Restore USB tracing; remove unused field in a structure. Remove + configuration settings that are no longer used. Fix configuration + selecting.. was setting the port number, not the configure ID. Also + add a configuration option to select the default configuration. + - apps/system/composite: Add a configuration option to the boardctl() + calls to support multiple composite device configurations dynamically. + - apps/system/composite: Remove references to USBMSC. There still + dependencies on CDC/ACM in the serial USB trace output. + - apps/system/telnet: Add Telnet Chat deamon and client from + libtelent. + + * Platform-Specific Support (apps/platform) + +Bugfixes. Only the most critical bugfixes are listed here (see the +ChangeLog for the complete list of bugfixes and for additional, more +detailed bugfix information): + + * Core OS: + + - Fix ELF loader up_checkarch on ARM arch. From Cristian Condurache. + - pthread_mutex_unlock(): Missing check for the case where + pthread_mutex_lock() is called when the mutex is not locked. In that + case, it would increment the underlying semaphore above 1. This is + the fix for a problem noted by initialkjc@yahoo.com. + - sig_timedwait(): Pending signal structure used after it has been + releasd. From anonymous Bitbucket Issue 59. + - mm_mallinfo: do heap end debug assert check with heap semaphore held. + From Jussi Kivilinna. + - sched/: Fix return value in sched_setaffinity(). From Masayuki + Ishikawa. + - Work Queues: work_queue() must cancel existing work prior to queuing + new work, otherwise the work queue list structure can become + corrupted. Problem noted by Pascal Speck. + - waitpid(): Corrects two problems when CONFIG_SCHED_HAVE_PARENT + + CONFIG_SCHED_CHILD_STATUS are enabled: (1) Was erroring out if the + waited for task had already exited, and (2) was not freeing resources + when a wait was completed. From Boris Astardzhiev. + + * File System/Block and MTD Drivers: + + - VFS poll(): Fix timeout calculation. From Jim Paris. + - VFS poll(): Fix poll for regular files and block devices. Open Group + documentation says that poll (and select) support regular files and + that 'Regular files shall always poll TRUE for reading and writing'. + From Jussi Kivilinna. + - VFS epoll(): Fix epoll_wait function. From Simon Piriou. + - Smart FS: Fix wrong freeing of device structure and use-after-free + issues on error paths. From Jussi Kivilinna. + - MTD FLASH drivers: The byte write method of several drivers had a + cloned error: It was not locking the bus while performing byte write + operations. + - MTD M2PX: If we READ while a write/erase is pending, the command is + ignored and the write/erase continues. If we dont catch this situation + we will return garbage to the user because the flash will not execute + the command. So READ MUST wait for write completion, and before that, + the bus must be locked since it's a precondition to calling + waitwritecomplete(). From Sebastien Lorquet. + - MTD FLASH drivers: Clone Sebastien Lorquet's m25px change to at25, + is25xp, ramtron, and sst25xx. + - MTD W25: Add missing locking and fix SPI_SELECT usage for + w25_unprotect. From Jussi Kivilinna. + - MTD W25: Wait for BUSY flag to clear in w25_readid and + w25_unprotect. W25Q128 datasheet says that all instructions expect + 'Read Status Register' and 'Erase/Program Suspend' are ignored when + BUSY flag in status register is '1'. Therefore wait for busy flag to + clear in w25_readid() and w25_unprotect(). From Jussi Kivilinna. + - Automounter: FS_AUTOMOUNTER should depend on SCHED_LPWORK. From + Nickolay Semyonov. + + * Networking/Network Drivers: + + - TCP Listen: Throw error when error happens in the tcp_listen + function. From Roland Takacs. + - Nework Device Management: Do not search net device when all-zeros + address is used. From Roland Takacs. + - Network Device Management: Fix a error in netdev_register(); it was + not handling device names properly when TUN is the only network device. + - Network Device Management: Fix netdev_dev_lladdrsize(). In some + configurations, it could return the wrong size for the address of a + packet radio. + - Network Device Management: Fix typo for 802.11 devices in + netdev_register(). Was being masked before because depended on + CONFIG_NET_MULTLINK. + - TUN Driver: Use critical section instead of semaphore in + tun_ifdown(). From Masayuki Ishikawa. + - TUN Driver: Do all polling on worker thread. Otherwise, the stack + gets very deep. + - TUN Driver: Currently cannot support TAP mode unless Ethenet is + enabled. + - netdb: Fixed buffer size used for sending DNS queries should depend + on the configured DNS name size. From Ritjaina. + - UDP networking: The TTL (time to live) was not being set in the IPv4 + or IPv6 header unless the UDP socket was bound. + - UDP Networking: Fix a copy-paste error that could effect networking + when both IPv4 and IPv6 are enabled. + - UDP Networking: When upd_input() cannot process a packet, it returns + ERROR so that network drivers may try calling ipv4_input() later. In + this case, it must also set d_len to zero. Otherwise, all network + drivers will assume tht there is also an outgoing packet. This + results in a gratuitous ARP. + - TCP Networking: Correct some issues that prevent TCP from working + correctly when both IPv4 and IPv6 are enabled. + - TCP Networking: TCP disconnection callbacks are not retained in a + list. This will support multiple callbacks per lower-level TCP + connection structure. That is necessary for the cae where a socket is + dup'ed and shares the same lower-level connection structure. NOTE: + There still needs to be a call to tcp_start_monitor() when the socket + is dup'ed. + - TCP Networking: Start the network monitor for a socket when a TCP + socket is dup'ed. + - TCP Networking: If one of the dup'ed socket's is closed, then network + monitor resources associated with that one socket must be recovered. + Also, in the event that socket is being used on one thread, but then + closed on another, any threads waiting for events from the socket + should be informed of the closure. That latter requirement is not + implemented because current data structures do not support it. + - TCP Networking: Fix a race condition. The accept() operation is + performed with the network locked. However, the network is unlocked + BEFORE the connected state is set. Therefore, a context switch may + occur and the socket may no longer be connected when it is marked so. + Noted by Pascal Speck. + - Network routing tables: Fix a compilation error when IPv6 and + routing are enabled. + - Network procfs: Fix some spacing when both IPv6 and IPv4 are enabled. + - Network Local Sockets: Fix accept for local stream sockets. From + Jussi Kivilinna. + - Network Local Sockets: Fix server lc_waitsem overflow. From Jussi + Kivilinna. + - IPv6 Networking: Remove comparisons to the address with all ones + set.

Otherwise, notification handlers + may be operating with a stale pointer. + - IEEE 802.15.4 MAC: Improves internal timer logic to handle work + serially. Before, the MAC timer used a watchdog to schedule work with + the high priority worker queue. However, since everything in the MAC + is supposed to be serialized through the use of the high priority work + queue, but the timer uses a watchdog, there are some unintended + consequences. To simplify, we now use the delayed work feature of the + work queue.

From Matt Thompson. + - SAMD21 SPI: I was having issues with the bus freezing up .. slaves + holding SDL low.. so I rewrote a good portion of the interrupt logic + based on the application notes from Atmel. One major improvement is + using the RXNACK flag in the STATUS register, which indicates that no + device responded to an address packet.

From Matt Thompson. + + * Microchip/Atmel SAMv7 Drivers: + + - SAMv7 TWIHS: TWIHS driver add reference counting. From David Sidrane. + - SAMv7 CAN: We discovered a problem with the samv7 mcan driver which + results, under some circumstances, in a very high CPU load. The + problem occurs, and is easily reproducible, if the device is connected + to a CAN network with a wrongly configured CAN speed (baud rate). In + our tests we set the CAN speed of the device to 1000000 and the speed + of the other CAN nodes to 500000. The device is restarted and sends a + CANopen "bootup message" to the CAN network. This results in huge + amount of errors messages on the CAN bus, probably because of the CAN + feature for acknowledging error messages. The error messages cant be + read by the device because of the misconfigured CAN speed, instead the + CAN chip reports lots of errors, which are reported to the application + which uses the CAN driver (CONFIG_CAN_ERRORS is enabled). The CAN + errors are reported from the CAN chip via interrupts and thus the + interrupt load is very high in this scenario. To fix the problem the + driver now disables each RX error interrupt after it is occurred. The + RX error interrupts are turned back on if at least one CAN message is + received successfully. From Stefan Kolb. + - SAMv7 CAN: I discovered while working on the SAMV7 mcan driver that + the implementation of the CAN error handling is suboptimal. In the + current implementation the many errors are implemented as pending + errors. But those errors are not pending, the errors occurred and are + gone directly afterwards. This commit changes the described behavior + and simplifies the handling of CAN errors.

From + Jeff. + +NuttX-7.23 Release Notes +------------------------ + +The 123rd release of NuttX, Version 7.23, was made on December 4, 2017, +and is available for download from the Bitbucket.org website. Note +that release consists of two tarballs: nuttx-7.23.tar.gz and +apps-7.23.tar.gz. These are available from: + + https://bitbucket.org/nuttx/nuttx/downloads + https://bitbucket.org/nuttx/apps/downloads + +Both may be needed (see the top-level nuttx/README.txt file for build +information). + +Additional new features and extended functionality: + + * Core OS: + + - sem_open() should return SEM_FAILED on any failures. This is change + in the POSIX specification since the original sem_open() was written + so many years ago. + - exec(): The non-standard interface exec() is now enshrined as a + official NuttX API. I really dislike doing this but I think that + this is probably the only want to load programs in the protected + mode. It is currently used by some example code under apps/ that + generate their own symbol tables for linking. Other file execution + APIs relay on a symbol table provided by the OS. In the protected + mode, the OS cannot provide any meaning symbol table for execution + of code in the user-space blob so that is they exec() is really + needed in that build case. And, finally, the interface is + completely useless and will not be supported in the KERNEL build + mode where the contrary is true: An application process cannot + provide any meaning symbolic information for use in linking a + different process. + - OS Internal Functions: Rename many OS internal functions so it is + clear that they are not part of the application interface. All + internal functions with the sem_* prefix became nxsem_*, sig* become + nxsig_*, mq_* become nxmq_*, etc. + - Cancellation Points: Add new cancellation point interface, + check_cancellation_point(). + - Signals: Add logic to wake up a thread that is waiting on a signal + if it is canceled. + - sigtimedwait(): Add logic to suppress the wait if there is a + pending cancellation. + - clock_nanosleep(): Implement clock_nanosleep(). nanosleep() is now + reduced to a libc wrapper around clock_nanosleep(). + - task_delete(): Do not permit user applications to delete kernel + threads. + - kthread_create(): Rename kernel_thread() to kthread_create() for + better naming consistency with task_create() and kthread_delete(). + - boardctl(): Remove the BOARDIOC_GRAPHICS_SETUP command. + - TCB: Move POSIX thread specific data from pthread TCB to common TCB + structure. This change allows using pthread_getspecific and + pthread_setspecific from main thread. Patch also enables using + pthread data with config option CONFIG_DISABLE_PTHREAD=y. From Jussi + Kivilinna. + - mm: Remove the CONFIG_GRAN_SINGLE configuration option. It adds no + technical benefit (other than some minor reduction in the number of + interface arguments) but adds a lot of code complexity. Better + without it. + - mm: Add a function to get information about the state of the + granule allocator. This is the moral equivalent of mallinfo(). + + * File Systems/Block and MTD Drivers + + - MT25Q Serial FLASH: Add support for Micron MT25Q series MT25Q128. + From Sebastien Lorquet. + - MX35LFxGE4AB: Add an MTD driver for Macronix MX35LFxGE4AB serial + NAND flash. From Ekaterina Kovylova. + - FileMTD: Add block device MTD interface. Block MTD interface + allows using block device directly as MTD instead of having to use + file-system in between. NOTE that this provides the opposite + capability of FTL which will let you use an MTD interface directly + as a block device. From Jussi Kivilinna. + - BCH: The character driver to block device access now supports an + IOCTL to get the geomtry of the underlying block device. + - mkfatfs: Remove mkfatfs from the OS. This is a user-space + application and belongs in apps, not in the OS. + - procfs: Implements procfs /proc/fs/blocks and /proc/fs/usage files, + replacing the NSH df command. Also implements procfs /proc/fs/mount + file, replacing the NSH mount command when there are no arguments. + - procfs: Add /proc/meminfo. This is an alternative way to get the + information that was previoulsy available in apps/system/free. + apps/system/free was removed beause it made illegal calls into the + OS violating the portable interface. This new procfs entry provides + the same information with no such violation. it also provides + information about the kernel heap (formerly /proc/kmm), about the + use of program memory(formerly /proc/progmem). And also information + for the page table usage in the KERNEL build. + - UserFS: Adds the UserFS client and of the UserFS feature in + general. Initially used Unix domain local sockets instead of + message queues. Easier to transfer big data in local sockets than + message queues. However, that lead to certain inescapable deadlock + conditions So the IPC was converted to UDP LocalHost loopback + sockets. The problem with the local sockets is that they do require + operations on the top level pseudo-file system inode tree. That + tree must be locked during certain traversals such as enumerate + mountpoints or enumerating directory entries. This conversion is + unfortunate in the sense that Unix local domain sockets are + relatively lightweight. LocalHost UDP sockets are much heavier + weight since they rely on the full UDP stack. + + * Graphics/Display Drivers: + + - Framebufer character driver: Add framebuffer character device driver. + - LCD Framebuffer: Add support for a generic front-end that will + convert any LCD driver into a framebuffer driver. + - Framebufer character driver: Include support for LCD drivers that + use a simulated framebuffer and must receive explicit notification + when there is an update to a region in the framebuffer. + - LCD: Make LCD driver configuration indepently selected from NX + graphics configuration. This makes things awkward and loses some + error checking but is a necessary step in order to make LCD drivers + usable when the NX graphics system is disabled. + + * Networking/Network Drivers: + + - Networking: Add implementation of logic for SIOCGIFCONF and + SIOCGLIFCOF IOCTL commnds. + - Network IOCTLs: Add support for the SIOCGIFBRDADDR ioctl() command. + - Routing Tables: Permit IPv4 and IPv6 routing tables to be of + different sizes. + - Routing Tables: Adds support for read-only routing tables. Prior + to this change, routing tables were only support in RAM and had to + be initialized with explicit logic to add the necessary routes to + the routing table. With this change, routes may be defined in the + pre-initialized, read-only routing table provided by the + board-specific logic. + This would be particularly useful, for example, in the case where + there is only a single network adaptor and you want all output + packets to go to the single adaptor in all cases. So for that + behavior you could add a read-only routing table to the + board-specific long that contains a single entry, the default route: + 0.0.0.0/0. + - Routing Tables. Added support for routing tables in files in a file + system. This might be useful for customized, per-unit routing + tables. There are two issues with it however: + 1. Reading from file system on a per packet basis could be slow. I + think it probably should have a small, in-memory cache of most + frequently used routes for good problem. + 2. Currently the delroute logic is disabled due to a problem with + the design. NuttX does not currently support truncate(). + Therefore, it is not possible to delete entries from the routing + table file. In this current implementation, that leaves the last + entry intact at the end of the file. An alternative design + might include a tag on each record to indicate if the record is + valid or not. That would work but would add complexity to the + other routing table functions. + - Routing Tables: Add support for an in-memory routing table cache in + order to improve performance when the routing table is retained in a + file. The cache holds the most recently used routing table entries + and so can eliminate some file access. Flush the in-memory cache + when any entry is deleted from the routing table. When a router + matching an IP address is found, add the routing table entry to the + cache. + - Routing Tables: Add logic to mark a route as most-recently-used in + the route cache. + - ICMP: This change adds support for semi-standard IPPROTO_ICMP + AF_INET datagram sockets. This replaces the old ad hoc, nonstandard + way of implementing ping with a more standard, socket interface. + - ICMPV6: This commit adds support for semi-standard IPPROTO_ICMP6 + sockets. This is a replacement for the non-standard ICMPv6 ping + support that violated the portable POSIX OS interface. + - ICMPv6: Add option to manually specify router prefix in router + advertisement message. From Sakari Kapanen. + - Local Sockets: This commit modifies the Unix domain local socket + design. Local sockets are built on top of pipes. The Local socket + implementation maintained file descriptors to interrupt with the + pipes. File descriptors have the bad property that they are valid + only while running on the thread within the task that created the + local socket. + As a policy, all internal OS implementations must use "detached" + files which are valid in any context and do not depend on the + validity of a file descriptor at any point in time. This commit + converts the usage of file descriptors to detached files throughout + the local socket implementation. + + * Wireless Networking/Wireless Drivers: + + - IEEE-802154: Adds support for receiving MAC events via IOCTL through + socket interface. From Anthony Merlino. + - IEEE-802154: Simplifies notify() and rxframe() calls to a single + notify() call. dataind's and all other "notifs" are now "primitives" + which aligns with standard terminology From Anthony Merlino. + - MAC802154: Add support for getting promiscuous mode state From + Anthony Merlino. + - MAC802154 Character Driver: When in promiscuous mode, the char + driver sends the entire frame, including the MAC header. This + change adds an offset field indicating the header-payload boundary. + It is set to 0 when not in promiscuous mode as the header is not + passed to the application + - 6LoWPAN: Remove CONFIG_NET_6LOWPAN_FRAMELEN. In this case where + multiple radios are supported, this may not be a constant. 6LoWPAN + now always queries the driver to get the maximum frame length. + - 6LoWPAN: Support sending to a router that is on-link and may be + able to forward the packet for us if the destination is not + reachable directly. From Anthony Merlino. + - XBee: Adds XBee S2C (802.15.4 firmware) support. XBee driver + emulates mac802154 interface. From Anthony Merlino. + + * Other Common Device Drivers: + + - PowerLED: Add upper-half driver for high power LED driver (powerled) + From Mateusz Szafoni. + - RTC Driver: Add periodic alarms to upper and lower halves. From + Juha Niskanen. + - Pipes: Fix writing large buffers not triggering POLLIN for reader + poll. From Jussi Kivilinna. + - USB CDC/ACM Device: Add support for RX flow control to the CDC/ACM + driver. + - USB CDC/ACM Device: Add support for flow control TERMIOs in CDC/ACM + driver. + - USB RNDIS Device: Add RNDIS-over-USB driver. From Sakari Kapanen + with added Hi-Speed support from Masayuki Ishikawa. + - Loop Driver: Don't use file descriptors... Use the internal file + system interfaces so that the loop device can be shared across + threads. + - APA102 LED controller: Add driver for APA102 LED controller. These + LEDs are used on LED Strips and are controlled over SPI. + - INA219. Add INA219 Driver. The INA219 is a combined voltage and + current sensor that can measure up to 26 volts and a current that + depends on an external shunt resistor. Connection happens via + i2c/smbus and the chip features a power supply rail that is + independent from the measured voltage, so it can measure low + voltages. Right now it measures bus voltage and current, and does + not use the internal calibrated current reading, nor the available + power measurement. From Sebastien Lorquet. + - PCA9555: The IRQ subsystem now supports passing a void * parameter + to IRQ handlers. Use that method to support multiple PCA9555 + devices, by passing a pointer to the device to the board defined IRQ + handler. Now the CONFIG_ for multiple PCA devices just allocates + device structures dynamically instead of statically when not enabled. + The same interrupt handler is entered with the device structure + parameter in all situations, multiple or single PCA. One should + still be careful if multiple PCA devices share the same IRQ. From + Sebastien Lorquet. + - APDS-9960: Add driver for the APDS-9960 gesture sensor. From Alan + Carvalho de Assis. + - MAX7219: Add support to MAX7219 LED Matrix as LCD interface. From + Alan Carvalho de Assis. + - WM8774: Add WM8774 audio DAC support.

This includes several register definition header + files (some from Alan Carvalho de Assis), basic interrupt handling + logic, boot-up files, GPIO support, tickless timer, build and + configuration logic + + * Broadcom BCM2708 Boards: + + - Raspberry Pi Zero. Basic board support at configs/pizero. Untested + in this release and still some remaining issues. + + * Infineon XMC4xxx Boards: + + - XMC4500-Relax: Add config for UART3 on RXD P0.0 and TXD P0.1 pins. + From Alan Carvalho de Assis. + + * NXP Freescale LPC17xx Boards: + + - Open1788: Add initialization of Framebuffer driver.

From Masayuki + Ishikawa. + - LC823450: Add IPL2 support. From Masayuki Ishikawa. + - LC823450: Add I2S support. From Masayuki Ishikawa. + - LC823450: Add auto LED for CPU activity. From Masayuki Ishikawa. + + * On Semiconductor LC823450 Boards + + - LC823450-XGEVK: Enable ADC and watchdog driver. From Masayuki + Ishikawa. + - LC823450-XGEVK: Add IPL2 support. From Masayuki Ishikawa. + - LC823450-XGEVK: Add WM8774 support. From Masayuki Ishikawa. + - LC823450-XGEVK: Add auto LED support. From Masayuki Ishikawa. + - LC823450-XGEVK: Enable CONFIG_SMP for audio. From Masayuki Ishikawa. + - LC823450-XGEVK: Add rndis configuration. From Masayuki Ishikawa. + + * STMicro STM32: + + - ARM Kconfig: Add support for classic ARM11 architecture selections. + - STM32 Tickless: Removes the restriction to 16-bit counts when a + 32-bit timer is used for tickless operation on the stm32. As it + was, the restriction is very limiting, especially if one wants high + granularity and large achievable intervals and has the hardware + (namely the 32bit timers) available. From Rajan Gill. + - STM32 L4 Kconfig: Add some L486 and L496 chips. From Juha Niskanen + - STM32 F7: Adds architecture support for the STM32 F72x and F73x + families. From Bob Feretich. + - STM32 F7: Allow changing voltage output scaling setting and + prevents enabling over-drive mode for low frequencies (STM32 F74xx, + 75xx, 76xx, 77xx). From Jussi Kivilinna. Changes replicated for + the 72xx and 73xx families. + + * STMicro STM32 Drivers: + + - STM32 ADC: Added support for ADC's IO_ENABLE_TEMPER_VOLT_CH ioctl + on STM32F10XX and STM32F20XX. From Dmitriy Linikov. + - STM32 Wakeup: Add logic for enabling wakeup pins. From Oleg Evseev. + - STM32 PWR: Adds stm32_pwr_getsbf and stm32_pwr_getwuf functions + that return the standby flag and the wakeup flag PWR power + control/status register. From Oleg Evseev. + - STM32 HRTIM: Sdd support for capture, chopper, deadtime and dump + registers. From Mateusz Szafoni. + - STM32 RTC: Canceling an alarm marks it as inactive. From Juha + Niskanen + - STM32 Serial: Add interface to get uart_dev_t by USART number, + stm32_serial_get_uart(). From Juha Niskanen. + - STM32 F33xx ADC: Initial ADC support for the STM32F33XX. From + Mateusz Szafoni. + - STM32 F33xx ADC: Add ADC DMA support to STM32F33 configuration. From + Mateusz Szafoni. + - STM32 L4 ADC: Port analog watchdog ioctl commands from the Motorola + MDK. From Juha Niskanen + - STM32 L4 ADC: Add option for routing ADC data to DFSDM, fix DFSDM + DMA. From Juha Niskanen + - STM32 L4 ADC: Add PM hooks from Motorola MDK + - STM32 L4 FLASH: Add function for modifying device option bytes, + From Juha Niskanen. + - STM32 L4 DFSDM: Add peripheral support for digital filters for + sigma-delta ADCs. Initial version. Timer trigger support is not + completed and there is some issue with DMA. From Juha Niskanen. + - STM32 L4 I2C: Port then STM32 F7 I2C driver to STM32 L4. STM32L4 I2C + driver is in work-in-progress state (plentiful of TODOs and + #warnings) and lags many features found in more up-to-date STM32 I2C + drivers. The peripheral on STM32F7 and STM32L4 are identical except + for L4's 'wakeup from stop mode' flag and STM32F7's I2C driver is in + more 'ready to use' state. The I2C clock configuration is kept the + same as before (I2CCLK = PCLK1 80 Mhz) instead of switching to + STM32F7 arch default that is I2CCLK=HSI. Further work would be to + add configuration option for choosing I2C clock source instead of + current hard-coded default. From Jussi Kivilinna. + - STM32 L4 RTC: Add up_rtc_getdatetime_with_subseconds + - STM32 L4 RTC: Change maximum alarm time from 24h to one month. From + Juha Niskanen. + - STM32 L4 RTC: Add support for periodic interrupts with + (experimental) CONFIG_RTC_PERIODIC. From Juha Niskanen. + - STM32 L4 SDMMC: Add support for an SDMMC driver. From Miha Vrhovnik. + - STM32 L4 Serial: Suspend serial for Stop mode. From Juha Niskanen. + - STM32 L4 Serial/PM: STM32L4 serial PM interface improvements: + Check rx/tx buffers for pending data in pmprepare. Remove adhoc PM + interfaces and move serial suspend functionality behind CONFIG_PM. + From Jussi Kivilinna. + + * STMicro STM32 Boards: + + - STM32F103-Minimum: Add board support for APA102 driver.

From Alan Carvalho + de Assis. + - STM32 F4 Discovery: RNDIS support on STM32F4Discovery + DM-STF4BB. + NOTE: MAC address for the host side starts 0xaa. This assignment + scheme should be fixed later. From Masayuki Ishikawa. + - STM32 F4 Discovery: Add STM32F4 Discovery board support for + Nunchuck joystick. From Alan Carvalho de Assis. + - STM3240G-EVAL: Add a configuration for testing the Framebuffer + character driver using the LCD framebuffer front. + - STM3240G-EVAL: Mount procfs if enabled. + - STM3240G-EVAL: Add support for pdcurses and the pdcurses demo + programs in the 'fb' configuration. + - Clicker2-STM32: Adds SD card, automount, and syslog file + support and fixes a few minor issues. From Anthony Merlino. + - Clicker2-STM32: Adds support for USB RNDIS device. From Anthony + Merlino. + - Olimex STM32-H407: Add serial support on the on-board UEXT + connector. Add USART6 for UEXT connector. Add nsh_uext + configuration and README update. From Jan Pobrslo. + - Nucleo-F410RB: Add support for the nucleo-F410RB board. From + Gwenhael Goavec-Merou. + - STM32F429i-DISCO: Add framebuffer driver initialization. Add a + framebuffer (fb) configuration. + - STM32F429i-DISCO: Add logic to auto-mount procfs. Enable procfs in + all configurations that use NSH. + - STM32F429i-DISCO: Enable support for the STMPE811 touchscreen + controller. Enable touchscreen and also the touchscreen testa at + apps/examples/touchscreen in the fb configuration. + - STM32F429i-DISCO: Convert NxWM configuration to use LTDC + framebuffer driver instead of SPI serial. Also reduce number of + layers from 4 to 1 in fb configuration. Only one layer is used. + - STM32L476-MDK: Add support for the on-board LEDs. + - Nucleo-L496ZG: Add DFSDM initialization.

From Alan + Carvalho de Assis. + - Nucleo-144: Adds support for the Nucleo-144 boards with + STM32F722ZE. From Bob Feretich. + + * ZiLOG Z80 + + - z80/include: compiler.h, limits.h, types.h: Update SDCC/z80 files + to include support for long long, inline, __FILE__, and __func__. + + * C Library/Header Files: + + - include/: Add stdnoreturn.h. Holds definitions for the C11 + noreturn keyword. Applies to C too. + - include/netinet/tcp.h: Add trivial standard tcp.h header file. + - libc: Add support for readv() and writev(). + - libc: Adds tcflow(). + - libc: Add support for sigwait(). + - libnx: Changes to allow the font subsystem to be built without + enabling the entire graphics system (CONFIG_NX). Adds + CONFIG_NXFONTS and CONFIG_NXGLIB. Needed to duplicate some Kconfig + setting for NXFONTs if it can be configured and built independently + of NX. + + * Tools: + + - tools/configure.sh: Add special support so that you can start with a + windows native configuration and install on a different host (and + vice versa). + - tools/configure.c: Duplicate new functionaity added to configure.sh. + - tools/configure.sh: This commit adds a -m option for macOS. For + anyone not aware, Apple renamed OSX to macOS recently; thus the 'm' + instead of 'o'. This does not change the other uses of *_OSX to + macOS. From jeditekunum. + - tools/configure.c: Update functionality to match last change to + tools/configure.sh. + + * NSH: apps/nshlib: + + - apps/nshlib: mount command no long uses the non-standard OS + interface foreach_mountpoint(). Now simply cats /proc/fs/mount + when there are no arguments to the mount command. + - apps/nshlib: df command no long uses the non-standard OS interface + foreach_mountpoint(). Now simply cats /proc/fs/blocks or + /proc/fs/usage. + - apps/nshlib: The free commands no longer used mallinfo() to get + the state of the use heap. Two reasons: That is not useful + information in the kernel build. And (2) there are other memory + resources of interest in other configurations such as the Kernel + heap in PROTECTED and KERNEL builds, and the prog mem uses when + FLASH is used to hold modifiable data. The free command has been + extended to just dump the content of procfs entries and to include + all of these other memory resources of the procfs entries are + available. + + * Examples/Tests: apps/examples: + + - apps/examples/fb: Add a simple test for the framebuffer character + driver.. + - apps/examples/ostest: sem_open() now returns SEM_FAILED in the + event of a failure. + - examples/ostest: Extend cancellation test to make sure that + cancelable threads waiting on a message queue or on a signal can be + canceled. + - Added a simple reader example for the LIS3DSH acceleration sensor + on STM32F4Discovery. From Florian Olbrich. + - apps/examples/apa102: Add a Rainbow example for APA102 LED Strip. + From Alan Carvalho de Assis. + - apps/examples/flowc: Add a simple test of serial hardware flow + control. + - Add powerled driver example. From Mateusz Szafoni. + - apps/examples/ina219: A simple infinite loop that polls the INA219 + sensor and displays the measurements. From Sebastien Lorquet. + - apps/examples/alarm: Add options for reading alarm value and + canceling it. From Juha Niskanen. + - Add -n samples to lm75 app and replace Centigrade with Celsius. + From Alan Carvalho de Assis. + - apps/examples/adps9960: Add ADPS-9960 example. From Alan Carvalho + de Assis. + - apps/examples/obd2: Add OBD2 example application. From Alan + Carvalho de Assis. + - apps/examples/userfs: Add a test case for verifying UserFS. + - apps/examples/smps: Add SMPS driver example. From Mateusz Szafoni. + - apps/examples/pdcurses: Bring in pdcurses demos and make them + conform to the NuttX coding style. + - apps/examples/pdcurses: Add a very simple example that just shows + the entire character set (7-bit only). It adapts to the size of + the framebuffer and, hence, can be used with very tiny displays. + In fact it looks really dumb on big displays. + - apps/examples/nunchuck: Add Nunchuck example application. From + Alan Carvalho de Assis. + + * File System Utilities: apps/fsutils: + + - apps/fsutils/mkfatfs: Move mkfatfs from the OS to here. + + * Network Utilities: apps/netutils: + + - apps/netutils/netlib: Add netlib_ipv6adaptor() and + netlib_ipv4adaptor(). + - apps/netutils/netlib: Add helpers for reading the routing table: + netlib_read_ipv4route() and netlib_read_ipv6route(). + - apps/netutils/netlib: Add new utilities netlib_ipv[4|6]router() + that can be used to determine the IP address of a router that would + be used some some destination IP address that is not locally + accessible. + - apps/netutils/ftpc: Adds support for IPv6 and fixes various + transfer issues. From Anthony Merlino. + + * CANUtilities: apps/canutils: + + - apps/canutils/libobd2: Add libobd2 for NuttX. From Alan Carvalho + de Assis. + + * Graphics: apps/graphics: + + - graphics/traveler: Convert to use the framebuffer driver. + - apps/graphics/pdcurs34: This commit brings the public domain + pdcurses library into NuttX. NuttX graphics support based on the + framebuffer character drivers has been integrated. Input is + currently limited to a discrete joystick driver. + + * Wireless Utilities: apps/wireless: + + - apps/wireless/ieee802154/i8sak: Adds socket interface support. You + can now use both socket or char driver to control the MAC layer. + From Anthony Merlino. + - apps/wireless/ieee802154/i8sak: Adds sniffer port option and a few + other get/set parameters. From Anthony Merlino. + - apps/wireless/ieee802154/i8sak: Changes 'notif' to 'primitive' + corresponding to the changes in the Kernel. From Anthony Merlino. + - apps/wireless/ieee802154/i8sak: Channel setting is now saved + locally, so when performing a startpan or assoc, the channel + previously set is still used, even though the MAC layer gets reset. + From Anthony Merlino. + - apps/wireless/ieee802154/i8sak: Adds ability to get/set rxonidle + setting for MAC layer. From Anthony Merlino. + - apps/wireless/ieee802154/i8shark: Adds i8shark, a sniffer "adapter" + that captures all 802.15.4 traffic, packages it into a Wireshark ZEP + packet, and sends it to a host running Wireshark From Anthony + Merlino. + + * System Utilities (apps/system) + + - apps/system/ping and ping6: This commit removes the ping and ping6 + commands from NSH and replaces then with the apps/system/ping and + apps/system/ping6 built-in commands. The NSH ping[6] commands had + to be removed because they violated the portable POSIX OS interface. + The apps/system/png and ping6 command uses the sem-standard + IPPROTO_ICMP and IPPROTO_ICMP6 socket interfaces. + + * Platform-Specific Support (apps/platform) + +Bugfixes. Only the most critical bugfixes are listed here (see the +ChangeLog for the complete list of bugfixes and for additional, more +detailed bugfix information): + + * Core OS: + + - Task Environment Creation: Fix an error in the duplication of the + child tasks environment in the special case where the parent's + environment was created, but then all of the variables were unset. + In that case, there is still an allocation in place but the size of + the allocation is zero. This case was not being handled correctly + when a child task attempts to create its environment and inherit the + zero-size partent environment. Noted by Anthony Merlino. + - timer_create(): Fix watchdog resource leak if cannot allocate a new + timer. From Bruno Herrera. + - OS Internal Functions: Internal OS functions should not return error + information via the user errno variable: This includes functions + like file_seek(), file_read(), file_write(), etc. The complete list + is too long to duplicate here (please refer to the ChangeLog for + details). + - OS Internal Functions: Not only should internal OS functions not + modify the errno variable, they should never introduce cancellation + points: psock_connect(), psock_listen(), psock_getsockopt(), etc. + The list is too long to duplicate here (please refer to the + ChangeLog for details). + - OS Internal Functions: Create OS internal versions of many + applications functions that were used by the OS. The new versions + differ from the application interfaces in that (1) they do not + return error information via the errno variable, and (2) they never + create cancellation points. This includes new internal interfaces + like nxsem_init() that is like sem_init(), etc. There are too many + to list here (see the ChangeLog for details). + - Task Exit: task_exithook.c fails to link if signals are disabled + because was unconditionally trying to send the SIGCHLD signal to the + parent in certain configurations. Noted by Jeongchan Kim. + - memalign(): Fix heap corruption caused by using unaligned chunk + size. Unaligned nodes generated by memalign later cause heap + corruptions when nodes are shrink further (for example, 24 bytes -> + 8 bytes, when alignment is 16 bytes). From Jussi Kivilinna. + - SMP: In sched/sched/sched_cpuselect.c, in order to find the cpu + with the lowest priority thread, we have to remember the already + found lowest priority. Noted by Anonymous in Issue #75. + - spinlocks: Disable local interrupts in spin_setbit() and + spin_clrbit() in order to avoid a deadlock condition. From Masayuki + Ishikawa. + - atexit()/on_exit(): Clear atexit()/on_exit() function pointer + before calling it. On most archs, up_assert() calls exit() so + without this change, if atexit() function triggers an assertion we + are in endless loop. From Juha Niskanen. + + * File System/Block and MTD Drivers: + + - tmpfs: Fixed directory unlocking in tmpfs_opendir. From Dmitriy + Linikov. + - fcntl(): fcntl() did not return success fail for F_SETFL. Reported + by Jussi Kivilinna. + - tcdrain(): tcdrain() was recently added to the NuttX C library. + But there is a problem. The specification of tcdrain() requires + that it be a cancellation point. In order to do this, tcdrain was + moved from the C library into the OS and the addition cancellation + point hooks were added. In non-FLAT builds, access via system calls + is also now supported. + - FS FAT: Fix hard-fault when listing contents of FAT root. From + Jussi Kivilinna. + - procfs: Correct a problem that was causing an apparent directory to + be reported as a file instead of a directory by opendir. This + happened after adding these three new procfs entries: fs/block, + fs/mount, and fs/usage. Of course, there is no directory fs in this + case, only three files that have fs/ in their relative pathnames. + The logic was detecting that fs was the name of the enty to report, + but it was then declaring that fs was a file (because fs/block is of + type file). This was fixed by adding a check for matching lenghts. + i.e., if strlen(fs) != strlen(fs/block), then report fs as a + directory instead of a file. + - procfs: Fix uptime being clse to maximum 32-bit value in certain + config. From Juha Niskanen. + + * Binary Loader: + + - binfmt/: Don't schedule starthook if there are no constructors. + + * Graphics/Display Drivers: + + - LCD: ILI9341 initialize method not permitted to set errno. + + * Networking/Network Drivers: + + - Networking: net/netdev/netdev_ifconfig.c: Was not returning all of + the address info. + - Networking: In some cases, packets are still not sent behind the + router. I found that NuttX sends the ARP requests not to the router + but to the target. Mistake in file net/route/netdev_router.c. From + Aleksandr Kazantsev. + - SIOCGIFCONF and SIOCGLIFCONF IOCTL commands should only report on + network adatpors in the UP state. + - recvfrom(): Fix double leave_cancellation_point on error path. + From Jussi Kivilinna. + - send(): Verify that sock descriptor is valid. Fixes assertion when + using send on closed socket. From Jussi Kivilinna. + - sendto(): Remove assert check for null psock and buf input + pointers. Removes check as 'psock == NULL' altogether because that + checked for later in psock_send and psock_sendto. Change null check + for 'buf' so that it is handled same as in recvfrom.c (return + -EINVAL instead of assert). From Jussi Kivilinna. + - sockgetname() files need to include udp/udp.h and tcp/tcp.h or + otherwise NET_UDP_HAVE_STACK and NET_TCP_HAVE_STACK are undefined + and the logic is never compiled. Noted by Anthony Merlino. + - dup()/dup2(): There was a reference counting problem in the TPC + logic of net_clone(). net_clone() which is the common logic + underlying dup() and dup2() for sockets. When net_clone() calls + net_start_monitor() and net_start_monitor() returns a failure + (because the underlying TCP connection) then net_clone() must back + out the reference count on the structure. Problem noted by Pascal + Speck and this implementation of the solution is based on his + suggestion. + - close(): There was a possible recursion that could eventually + overflow the stack. The error occurred when closing the socket with + inet_close() while a socket callback was still queued. When the + socket callback was executed by devif_conn_event(), this resulted in + a call to psock_send_eventhandler() with TCP_CLOSE flag set which + then called tcp_lost_connection(). tcp_shutdown_monitor() then + called tcp_callback() again, which again called + psock_send_eventhandler(), and so on.... Noted by Pascal Speck. + Solution is also similar to a solution proposed by Pascal Speck. + - inet: Add check for protocol before handing out TCP and UDP sockets. + - IP Forwarding: Fixes typo that caused build error when IP + forwarding was enabled with CONFIG_NET_ICMPv6_NEIGHBOR enabled as + well. From Anthony Merlino. + - IP Forwarding: Do not add link layer header size to d_len inside + devif_forward(). From Anthony Merlino. + - TCP Networking: When CONFIG_NET_TCP_WRITE_BUFF=y there is a + situation where a NULL pointer may be dereferenced. In this + configuration, the TCP connection's 'semi-permanent' callback, + s_sndcb was nullified in tcp_close_disconnect. However, other logic + in tcp_lost_connection() attempt to use that callback reference + after it was nullifed. Fixed in tcp_lost_connectino() by adding a + NULL pointer change before the access. This was reported by Dmitriy + Linikov in Bitbucket Issue 72. + - UDP Broadcat: Fix some issues with regard to UDP broadcast + handling. This is Bitbucket Issue #77. + - ICMP: Fix an error in the poll logic. It was assumed that the + input parmeter pvconn was valid. It was not. Instead, the poll + logic must work like the sendto() and recvfrom() logic: It must + keep a copy of the conn structure in the private data. + - ICMPv6: Fixes several errors preventing icmpv6_radvertise.c from + being compiled. Fixes conversions to network byte order (namely + vlifetime, plifetime, mtu). IPv6 source address is set to + link-local IP address instead of the address in the netdev + structure. This is in compliance to RFC 4861. RA didn't work on + Linux before this change. Finally, router prefix and prefix length + are derived from the IPv6 address and netmask in the netdev + structure. This seems to make more sense than using a predefined, + separate prefix from the config. From Sakari Kapanen. + - ICMPV6: icmpv6_input() needs to set d_len to 0 after consuming echo + reply, otherwise, garbage will get sent out. From Anthony Merlino. + - ICMPV6: Fix an error in the poll logic. It was assumed that the + input parmeter pvconn was valid. It was not. Instead, the poll + logic must work like the sendto() and recvfrom() logic: It must + keep a copy of the conn structure in the private data. + - IGMPv2 Send: Fix incoming IGMP checksum calculation.

From Anthony Merlino. + + * Common Drivers: + + - Serial: 16550 UART driver IOCTL method must not set errno; it must + return a negated errno value. + - LIS3DSH: Added the argument parameter (FAR void *arg) to the + interrupt handler provided by the LIS3DSH driver to fit the + definition for ISRs in xcpt_t.

From Mateusz Szafoni. + - STM32 CAN: Lower part of STM32 CAN driver + arch/arm/src/stm32/stm32_can.c uses all three hw tx mailboxes and + clears TXFP bit in the CAN_MCR register (it means transmission order + is defined by identifier and mailbox number). + This creates situation when order frames are put in upper part of + CAN driver (via can_write) and order frames are sent on bus can be + different (and I experience this in wild). Since CAN driver API + pretends to be "file like" I expect data to be read from fd the same + order it is written. So I consider described behaviour to be a bug. + Fixed by settin the TXFP bit in the CAN_MCR register (FIFO + transmit order). From comments by Alexey T, in Bitbucket Issue 73. + - STM32 HRTIM: Fix pclk calculation. From Mateusz Szafoni. + - STM32 HRTIM: Fix burst mode prescaler update.

From Dmitriy Linikov. + +NuttX-7.24 Release Notes +------------------------ + +The 124th release of NuttX, Version 7.24, was made on March 2, 2018, +and is available for download from the Bitbucket.org website. Note +that release consists of two tarballs: nuttx-7.24.tar.gz and +apps-7.24.tar.gz. These are available from: + + https://bitbucket.org/nuttx/nuttx/downloads + https://bitbucket.org/nuttx/apps/downloads + +Both may be needed (see the top-level nuttx/README.txt file for build +information). + +Additional new features and extended functionality: + + * Core OS: + + - SMP: Introduce spin_lock_irqsave() and spin_unlock_irqrestore(). + These APIs are simplified version of enter_critical_section() + and leave_critical_section() to protect data (e.g. registers) in + SMP mode. By using these APIs inside drivers, performance will + be improved. From Masayuki Ishikawa. + - System Timer: Replace critical section APIs with spinlock APIs. + (64bit only). If SMP=n or SMP=y && SPINLOCK_IRQ=n, this works + in the same way as before. If SMP=y && SPINLOCK_IRQ=y, performance + will be improved. From Masayuki Ishikawa. + - POSIX Timers: Replace critical section APIs with spin lock APIs in + clock_gettime.c. This change will improve performance for SMP + systems but nothing changes for non-SMP systems. In SMP mode, + the running TCB is not always at the g_readytorun.head. From + Masayuki Ishikawa. + - SMP: Introduce spin_lock_wo_note() and spin_unlock_wo_note(). These + APIs are used in sched_note.c to protect instrumentation data. The + difference between these APIs to exsiting spin_lock() and + spin_unlock() is that they do not perform instrumentation to avoid + recursive call when SCHED_INSTRUMENTATION_SPINLOCKS=y. From + Masayuki Ishikawa. + - Interrupts: Add a configuration option to show interrupt + information via a procfs file. + + * File Systems/Block and MTD Drivers + + - VFS: Add support for truncate() and ftruncate(). + - FAT, SmartFS, UserFS, UnionFS, TmpFS, NFS: Add truncate() support. + - FAT.

From Anthony + Merlino. + - apps/system/usbmsc: Added Kconfig options to configure write + protection for each LUN. From Fabio D'Urso. + - system/stackmonitor: Re-design the stack monitor so that it does not + make forbidden calls directly into the OS, breaking the portable POSIX + OS interface. It now properly uses the PROCFS file system to glean + information about stack usage. + +Bugfixes. Only the most critical bugfixes are listed here (see the +ChangeLog for the complete list of bugfixes and for additional, more +detailed bugfix information): + + * Core OS: + + - System Timer: Change the way that the 64-bit time is sampled. + Previously, we disabled interrupts before sampling the 64-bit + timer since the uint64_t access is not atomic on most CPUs. However, + disabling (local) interrupts does not work in the SMP case. In that + case, the timer interrupt may be running on only one of the CPUs; + disabling interrupts on a different CPU will provide no protection + from timer rollover. To work around this, logic was added that + samples 64-bit timer is sampled twice and if 32-bit rollover was + detected between samples, then loops until there is no rollover. + - POSIX Timers: In SMP mode, running TCB is not always at the head of + the g_readytorun list. This change removes DEBUGASSERT() to avoid + this condition. From Masayuki Ishikawa. + - Spinlocks: Add memory barrier operations in spin_unlock(). In ARM + document regarding memory barriers, SP_DMB() must be issued before + changing a spinlock state to SP_UNLOCKED. However, we found that + SP_DSB() is also needed to ensure that spin_unlock() works + correctly for network streaming aging test. From Masayuki Ishikawa. + - Sporadic Scheduler: Fix compiler error in Sporadic Scheduler when + priority inheritance is enabled. Noted by eunb.song@samsung.com + - Priority Inheritance: Fix some priority inheritance related issues + noted during review of logic. Also add some REVISIT comments for some issues noted in the design. + - boardctl: Remove the BOARDIOC_TSCTEST_TEARDOWN and + BOARDIOC_TSCTEST_SETUP boardctl() commands. Remove all + implementations of board_tsc_teardown(). Each board now initializes + the touchscreen controller as a normal part of its board bring-up. + board_tsc_setup() is gone; the touchscreen controller is now treated + like any other on-board device. + - configs: CONFIG_MAX_TASKS must be a power of 2. + - SMP: Introduce a new global IRQ clearing logic and tasklist + protection. The previous implementation of clearing global IRQ in + sched_addreadytorun() and sched_removereadytorun() was done too + early. As a result, nxsem_post() would have a chance to enter the + critical section even nxsem_wait() is still not in blocked state. + This patch moves clearing global IRQ controls from + sched_addreadytorun() and sched_removereadytorun() to + sched_resumescheduler() to ensure that nxsem_post() can enter the + critical section correctly. For this change, + sched_resumescheduler.c is always necessary for SMP configuration. + In addition, by this change, task_exit() had to be modified so that + it calls sched_resumescheduler() because it calls + sched_removescheduler() inside the function, otherwise it will cause + a deadlock. However, I encountered another DEBUGASSERT() in + sched_cpu_select() during HTTP streaming aging test on LC823450-XGEVK. + Actually sched_cpu_select() accesses the g_assignedtasks which might + be changed by another CPU. Similarly, other tasklists might be + modified simultaneously if both CPUs are executing scheduling logic. + To avoid this, I introduced tasklist protection APIs. With these + changes, SMP kernel stability has been much improved. From Masayuki + Ishikawa. + - SMP: Fix this_task() to be an atomic operation. In the previous + implementation, this_task() was defined in sched.h by using just a + macro current_task(this_cpu()). However, I found that this is not + atomic and actually sometimes switching CPU happened in executing + the macro when we tested audio steaming plus executing commands via + Telnet. This change resolves this issue by implementing atomic + this_task()in sched_thistask.c which is newly introduced. From + Masayuki Ishikawa. + - SMP: Implements a global scheduler lock capability as part of SMP + support. This allows the scheduler to be locked with no knowledge + or access to the TCB of the currently running task. This is + necessary because accessing the TCB of the currently running task + is, itself, a non-atomic operation. This global scheduler lock + capability was add just to support that atomic access to the TCB. + - SMP: Extend the last global lock change to work with the + LC823450-XGEVK which does not support the atomic fetch add but + does support disabling interprocessor interrupts. Disabling + interprocessor interrupts will also guarantee that the TCB address + calculation is atomic. + - SMP: Fix a infinite recursion problems that a recent changes + introduced into the i.MX6 SMP implementation. This is not seen + with the LC823450 because you can disable inter-processor interrupts + in that architecture; but you cannot in the ARMv7-A/GIC architecture. + - SMP: Remove SMP related logic in sig_dispatch.c. This change + prevents from a deadlock in up_schedulesigaction.c where inter-CPU + signal handling is actually implemented. arch/arm/src/armv7-m: Fix + signal handling for SMP. In previous implementation, signal handling + for SMP was incorrect. Thus, for example, if an inter-CPU signal + happened an incorrect tcb was signaled and caused ASSERT(). This + change fixes the issues and works for both inter-CPU signal handling + and signal handling on the same CPU. From Masayuki Ishikawa. + - Tasking: Add nxtask_create(). Kthread_create() and nxtask_create() + are internal OS functions and should not modify the errno variable. + Convert legitimate uses of task_create() to nxtask_create(). + Review handling of returned values from all uses of kthread_create() + (as well as nxtask_create()). + - Tasking: Threads started by board bring-up logic should be kernel + threads, not user tasks. + - Tasking: Threads started by drivers should be kernel threads, not + user tasks. + - Semaphore Usage: Added ECANCELED condition to DEBUGASSERT's + checking sem_wait result From Dmitriy Linikov. + + - errno: Add new internal OS function nxsched_setaffinity() that is + identical to sched_isetaffinity() except that it does not modify the + errno value. All usage of sched_setaffinity() within the OS is + replaced with nxsched_setaffinity(). + - errno: Internal functions sched_reprioritize() and + sched_setpriority() no longer modify the errno value. Also renamed + to nxsched_reprioritize() and sched_setpriority(). + - errno: Add new internal OS function nxsched_getscheduler() that is + identical to sched_getscheduler() except that it does not modify the + errno value. All usage of sched_getscheduler() within the OS is + replaced with nxsched_getscheduler(). + - errno: Add new internal OS function nxsched_setparam() that is + identical to sched_setparam() except that it does not modify the + errno value. All usage of sched_setparam() within the OS is + replaced with nxsched_setparam(). + - errno: Add new internal OS function nxsched_getparam() that is + identical to sched_getparam() except that it does not modify the + errno value (actually, the previous value erroneously neglected to + set the errno value to begin with, but this fixes both issues). All + usage of sched_getparam() within the OS is replaced with + nxsched_getparam(). + - errno: wd_start() is an internal OS function and should not set the + errno value. Reviewed and updated every call to wd_start() to + verify if return value is used and if so if the errno value is + accessed. + - errno: Fix several inappropriate accesses to get_errno() that were + missed in previous changes (some going back to nuttx-7.23). Add new + nxsched_setscheduler() and nxsched_getaffinity() which are + equivalent to their counterparts without the nx on front. These + versions do not modify the errno value. Changed all calls within + the OS to use these newer versions of the functions. + - errno: binfmt/, configs/, grahics/, libc/, mm/, net/, sched/: OS + references to the errno variable should always use the set_errno(), + get_errno() macros. + - drivers/, fs/ and libc/: OS references to the errno variable should + always use the set_errno(), get_errno() macros. + + * File System/Block and MTD Drivers: + + - FAT: CONFIG_FAT_MAXFNAME may not exceed NAME_MAX (CONFIG_NAME_MAX) + - NFS: Correctly infer file type. The file type is in struct + nfs_statinfo_s's ns_type field, not in the ns_mode field. From + Michael Jung. + - NFS: Fix buffer corruption. In case multiple read requests to the + NFS server are required to fill up the user provided buffer, + nfs_read() might write behind the end of said buffer. This is fixed + with this change. From Michael Jung. + - VFS: reopen() should return NULL when oflags is less than 0, not + equal to 0. Because negative value is returned on failure of + lib_mode2offlags() which converts the mode string into file open + mode flag. + - ProcFS: Fix an error in a common function that manages read data. + - drivers/mmcsd: Respect SDIO_CAPS_DMABEFOREWRITE on CMD25. From + Evgeniy Bobkov. + - AT24xx: Correct page size for AT24C02 part. From Alexander + Oryshchenko. + - mtd_config.c: Add still more error handling (to detect bad + underlying flash implementations). Remove MTD_ERASE that was + erasing data block instead of erase block. This is a partial + revert of 4f18b4. Reported-by: Pascal Speck + + * Graphics/Display Drivers: + + - drivers/lcd: Fix the default I2C address of SSD1306 OLED display + (7- vs 8-bit addressing) From Alan Carvalho de Assis. + - drivers/lcd: lcd_framebuffer.c does not need to include board- + specific board.h. + - include/lcd: Eliminate a warning from an SSD1306 header file by + adding a forward reference to struct i2c_master_s. From Sebastien + Lorquet. + + * Networking/Network Drivers: + + - ARP: Fix an error introduced when ICMP and ICMP6 socket support was + added in NuttX-7.3. A gratuitous ARP (or solicitation) was being + sent after receive of the ECHO replay (advertisement). + - ARP: Fix IGMP multicast address computation on Nuttx network stack. + This change fixes the IGMP address computation to allow multicast + UDP messages. The destination address was created with the incorrect + bytes of the given IPv4 address. From Louis Mayencourt. + - ioctl: The existence of the network driver ioctl() method should + depend on CONFIG_NETDEV_IOCTL rather than CONFIG_NETDEV_PHY_IOCTL. + The former enables the method, the later enables a subset of + possible driver IOCTLs. + - TCP: Write buffering logic should not wait for a free buffer if + the socket was opened non-blocking. + - TCP: Fixed bad return value handling in psock_tcp_send(). send() + expects psock_tcp_send() to return a negated errno value, not -1 + with the errno set (GN: I added same change for tcp_send_buffered.c + which has the same issue as tcp_send_unbuffered.c) From Pelle + Windestam. + - TCP: Fixes hardfault when network goes done and network monitoring + is in place. From Gianpaolo Ferroni Ariani. + - TCP: tcp_send_[un]buffered.c: Check routing table in + psock_send_addrchck(). Previously only ARP table was considered + when determining if the data will actually be sent. From Juho + Grundstrom. + - TCP: Generalize Juho Grundstrom's IPv4 change for IPv6 as well. + - UDP: Remove some conditional logic that was true if there is only a + single network device, but not true in the multi-device context. + - UDP: In sendto(), return EHOSTUNREACH if the network is down. + + * Common Drivers: + + - drivers/pipes: In poll logic, fix off-by-one error in calculation + of bytes in the buffer. Buffer calculation in pipe poll setup is + off-by-one when read index is larger than write index. This causes + poll() not getting POLLIN when buffer has one byte as calculation + gives zero bytes in buffer. From Jussi Kivilinna. + - drivers/audio: Improve stability of the WM8776 driver in SMP mode. + Apply irq_spin APIs to improve performance. Repeat to process a + message to avoid deadlock. From Masayuki Ishikawa. + - drivers/ioexpander: Fixed build of PCF8574 driver when its + interrupts aren't enabled by config. From Dmitriy Linikov. + - drivers/syslog: Fixes LOG_UPTO macro to include specified log level. + From Anthony Merlino. + - drivers/sensors: Fix HTS221 sensor reset with BOOT bit From Jussi + Kivilinna. + - drivers/loop: If we want to open read-only in losetup.c, flags + should be O_RDONLY not O_RDWR. From Fabio D'Urso. + - drivers/timers/ds3231.c: Correct some debug statements. From + Alexander Oryshchenko. + - drivers/sensors/lis2dh: Use realtime clock if monotonic is not + available From Juha Niskanen. + - drivers/i2c and drivers/spi: Fix compile error if + CONFIG_DISABLE_PSEUDOFS_OPERATIONS, fix bad NULL checks From Juha + Niskanen. + + * ARMv7-A: + + - Data Cache: Fix cp15_invalidate_dcache. In cases where more than + one dcache line was to be invalidated, a missing branch label + would result in a false branch target into cp15_flush_idcache. Also + the .size macro was fixed for both cp15_invalidate_dcache. From + Michael Jung. + - SMP: Port the signal-related SMP change by Masayuki Ishikawa to the + ARMv7-A family. + + * Extensa: + + - SMP: Port the signal-related SMP change by Masayuki Ishikawa to the + Xtensa family. + + * Infineon XMC4xxx Drivers: + + - XMC4xxx: Only setup USB clock when USB PLL is enabled From Alan + Carvalho de Assis. + - XMC4xxx: Fix USIC_BRG_SCLKCFG definition From Alan Carvalho + de Assis. + + * Microchip PIC32MZ + + - MIPS32: In up_idle, the kludge that was conditionally enabled if + the work queue was enable appears to be needed even when he work + queue is not enabled on the PIC32MZ. + - PIC32MZ: Fix some typos in debug instrumentation in pic32mz-gpio.c; + fix some typos related to UART5 configuration in pic32mz-serial.c. + + * Microchip/Atmel SAMD/L: + + - SPI: In sam_spibus_initialize(), the pinmux configuration was + smashing the previous CTRLA register configuration. There are + also some typos in samd_spi.h From Matt Thompson. + - SPI: Fixes g_spi2ops and g_spi2dev using incorrect values From Matt + Thompson. + - SPI: SPI must be disabled before changing the mode bits in CTRLA + register From Matt Thompson. + - DMA: Fix DMA controller support. From Matt Thompson. + + * NXP/Freescale LPC17xx Drivers: + + - LPC17xx: Disable LPC17 FDR when not used. If a boot loader set the + fractional divider (FDR) the baud rate in nuttx will be wrong + (multiplied by this fraction). So if it is not used, it should be + disabled. From Harald Gutsche. + + * NXP/Freescale Kinetis Drivers: + + - Kinetis: Correct some Ethernet PHY register bit tests for the + KSZ8081 PHY. From Stewart. + + * On Semiconductor LC823450 + + - arch/arm/src/LC823450: Add SP_DMB() into lc823450_testset.c. + In LC823450, ldrex and strex are not supported. So we implemented + up_testset() with H/W Mutex. However, there was a bug in memory + access order. This change ensures correct memory access order in + up_testset() for LC823450. From Masatoshi Tateishi. + + * STMicro STM32 Drivers: + + - STM32 F3 RCC: A flash wait state configuration. Flash latency must + be fixed according to sysclk frequency. If this operation is not + done or done after PLL configuration, the STM32 fail to continue + boot operation if the frequency if greater than 24MHz according to + the board variable STM32_SYSCLK_FREQUENCY. Tested on stm32f334-disco + board. From Gwenhael Goavec-Merou. + - STM32 RTC: Make STM32 usable with an external RTC. + - STM32 SPI: Removed unnecessary (and incorrect) speed limitation. + From Alexander Oryshchenko. + - STM32 SPI: I have a SPI bus with both Mode 0 and Mode 3 devices + on it. After performing SPI I/O to a Mode 0 device, switching to a + Mode 3 device locked up the SPI interface. Only zeroes would be + read. I traced the reason for the lock-up to arm/arm/src/stm32f7/stm32_spi.c function spi_setmode(). Changing + the mode causes a spurious SPI clock transmission that confuses the + stm32f7 SPI input hardware. This problem is solved by (1) changing + the SPI mode with SPI (and perhaps DMA) disabled, and (2) flushing + the receive FIFO if the mode change results in garbage in the FIFO. + From Bob Feretich. + - STM32 and STM32 F7: Remove confusing, redundant, and misleading + definitions of STM32_BKP_BASE from the F2, F3, and F4 memory + maps. Unlike the F1, these parts do not have a separate BKP address + region. The BKP registers are with the RTCC address regions. + stm32_bkp.h should only be used for STM32 F1. stm32_rtcc.h should be + used to access BKP registers on F2, F3, and F4. + - STM32 and STM32 F7: Architecture-specific code is not permitted to + modify the errno variable. + - STM32 F4 I2C: Correct some recent changes to STM32F4 I2C that broke + poll mode of operation. From Alexander Oryshchenko. + - STM32 F4 I2C: Corrections to STM32 F4 I2C to restore functionality. + From Alexander Oryshchenko. + - STM32 F4 I2C: Corrections to STM32 F4 I2C to fix the NORESTART + flag. From Alexander Oryshchenko. + - STM32 F7: Fixes a bug in multi-block SD-card operations on the + STM32F7 platform. DBLOCKSIZE must be the size of SD-card block, not + the total amount of transferred bytes. From Evgeniy Bobkov. + - STM32 F7: Fix undefined variable when using USART1 for other + purposes than UART (e.g. SPI). From Frank Benkert. + - STM32 F7: Backport RTC alarm setting changes from STM32L4. Most + notably this fixes RTC getting stuck issue when both alarms were + used. Root cause was writing RTC ISR register contents to RTC CR + register. From Juha Niskanen. + - STM32 L4 Flash: Change flash programming to use page buffer for + unaligned writes. From Juha Niskanen. + + * STMicro STM32 Boards: + + - Nucleo-L432KC: Fix some bogus logic noted by Fanda. + - configs/nucleo-* and configs/stm32l476vg-disco: Fix more + stm32_userleds.c bogus logic From Juha Niskanen. + - Nucleo-L432KC: Fixed nucleo-l432kc broken build when + CONFIG_USERLED_LOWER defined From Fanda. + - Nucleo-L432KC: Issue #85: /dev/userleds is not working for + Nucleo-L432KC fixed From Fanda Vacek. + - STM32F429I-Disco: Separate SPI4 from MTD init. I was trying to + attach a non-MTD peripheral to an STM32F429I Discovery Board's SPI4 + port and was hitting compilation problems, since CONFIG_MTD and + thus 'struct mtd_geometry_s' was not defined. This patch separates + SPI4 initialization logic from MTD initialization logic. From + Michael Jung. + - STM32F103-Minimum: Remove CONFIG_NX_LCDDRIVER dependence from + stm32_ssd1306.c From Alan Carvalho de Assis. + + * C Library/Header Files: + + - libc/stdio: In dtoa(), up_interrupt_context() is used in a debug + assertion. up_interrupt_context() is not available in the user-mode + phase of the PROTECTED or KERNEL build configurations. In those + configurations, enabling libc floating point support and debug + assertions will result in an undefined reference to + up_interrupt_context(). + - libc/netdb: Fixed parsing of DNS response packets having compressed + names ending with pointer. There were troubles parsing response + packets which have compression of QNAME/NAME field when only + trailing part of the name (not the whole name) is replaced with + pointer to another part of the packet. This commit fixes parsing of + such packets. Also I added checks to keep parsing only in bounds of + the read part of DNS response packet. From Dmitriy Linikov. + + * Tools + + - tools/*.c: Add #define _GNU_SOURCE to all C files that call + asprintf() to eliminate a warning. + - tools/cvsparser.c: Add a check to avoid access past the end + of a fixed size array + + * NSH: apps/nshlib: + + - apps/nshlib: Fix compile error when CONFIG_NSH_DISABLESCRIPT is not + defined. The field np_flags does not exist if scripting is disabled. + + * Examples/Tests: apps/examples: + + - apps/examples/touchscreen: Eliminate BOARDIOC_TSCTEST_SETUP. + + * Network Utilities: apps/netutils: + + - apps/netutils/ftpc: Fix some corner-cases that could cause FTP to + access past the end of valid data. + + * Wireless Utilities: apps/wireless: + + - apps/wireless/ieee802154/i8shark: Fixes special XBee compensation + by purposely chopping off the FCS. From Anthony Merlino. + +NuttX-7.25 Release Notes +------------------------ + +The 125th release of NuttX, Version 7.25, was made on June 3, 2018, +and is available for download from the Bitbucket.org website. Note +that release consists of two tarballs: nuttx-7.25.tar.gz and +apps-7.25.tar.gz. These are available from: + + https://bitbucket.org/nuttx/nuttx/downloads + https://bitbucket.org/nuttx/apps/downloads + +Both may be needed (see the top-level nuttx/README.txt file for build +information). + +Additional new features and extended functionality: + + * File Systems/Block and MTD Drivers + + - fs/cromfs: Added CROMFS file system. CROMFS is a commpressed, in- + memory, read-only file system based on LZF. + - fs/vfs: Added support for checking if a descriptor is a socket in + fstat(). From Pelle Windestam. + + * Graphics/Display Drivers: + + - drivers/lcd: Remove support for the Nokia6100 LCD. That LCD uses a + 9-bit SPI interface (the 9th bit being the command/data bit that is + normally a discrete). That communication was never successfully + integrated. I now believe that it would would require some special + support from the low-level, MCU SPI driver to manage that 9th bit. + The deleted code is still available in the Obsoleted repository. + + * Networking/Network Drivers: + + - net/tcp: Added support for TCP Keepalive, add SO_KEEPALIVE socket + option. Added socket options needed to manage TCP-keepalive and TCP + state machine logic to detect if that the remote peer is alive. + - net/tcp: In tcp_input(), add the logic to detect, decode, and + respond to TCP Keep-Alive packets. + - net/tcp: Extended support for sending to non-blocking tcp sockets. + From Pelle Windestam. + - net/bluetooth: Added support for AF_BLUETOOTH sockets. + - drivers/net: Added TAP (network bridge) mode to tun.c. In the + previous implementation, TAP mode did not handle a packet correctly. + Also, the driver did not set the link layer type and could not + assign the interface name. This change fixes such issues and supports + TAP mode correctly. From Masayuki Ishikawa. + + * Wireless/Wireless Drivers: + + - wireless/ieee802154: Added basic MAC support for RX-ENABLE.request + primitive From Anthony Merlino. + - wireless/ieee802154: Added MAC ackreq flag to TX descriptor for use by + radio driver. The radio layer is responsible for a full "transaction". + Because of differences in radio capabilities, the radio must be + responsible for the handling of acks and retransmissions. This commit + simply passes the ackreq meta-data flag along to the radio. Also + Fixes bug where primitive was freed when it shouldn't have been, + causing double free call. From Anthony Merlino. + - wireless/bluetooth: Bring in the Bluetooth stack from the Intel/ + Zephyr arduino101_firmware_source-v1.tar package. + - drivers/bluetooth: Added re-architected version of the Bluetooth + UART driver from the Intel/Zephyr arduino101_firmware_source-v1.tar + package. + - include/nuttx/wireless: Added a setbaud() method to the HCI UART + lower half interface that can be used to change the default BAUD + selection. + - wireless/bluetooth and include/nutt/net: Added support for Bluetooth + IOCTL commands. + - drivers/wireless/bluetooth: Added a NULL device to support some very + low level testing on the Simulator. + - drivers/wireless/cc3000: Eliminate support for the CC3000 wireless + part because it doesn't use the USRSOCKET. From Alan Carvalho de + Assis. + - drivers/wireless/ieee80211: Added BCM43428 support. From hhuysqt. + + * Other Common Device Drivers: + + - drivers/1wire: Added 1-wire subsystem and ds28e17 driver From Juha + Niskanen. + - drivers/1wire: Added PM hooks and unlink support to sht21 sensor + (allowing hot-swappable I2C bus from 1-wire converter). Unlike most + other unlink implementations in NuttX drivers, this one does not + allow any I2C operations after unlink, making it possible to + deallocate the I2C bus.

Basically copied + from STM32. From Michael Jung. + + * NXP LPC17xx Drivers: + + - LPC17xx: Added a configurable option to allow using a part of + LPC17xx's internal flash memory as a Memory Technology Device via + NuttX' mtd_progmem infrastructure. Tested with LPC1769. From + Michael Jung. + + * NXP LPC17xx Boards: + + - Olimex-LPC1766STK: Remove support for the Nokia6100 LCD.

From + hhuysqt. + - STM32 SDIO: Added internal pull-up option for SDIO pins. From Alan + Carvalho de Assis. + - STM32 F2/F4 ADC: Added Vbat measurement to ADC driver for + STM32F20xx and STM32F4xxx. As with the MCU temperature and VREFINT + measurement, this change requires user to enable the corresponding + channel first. For Vbat channel the ioctl cmd is + IO_ENABLE_DISABLE_VBAT_CH, and its arg should be a pointer to bool + which must be true to enable and false to disable the Vbat channel. + Moreover, since Vbat input contains a built-in voltage divider, it + is highly suggested to disable Vbat input channel after measurement + is done in order to prevent battery drain through the divider. From + Dmitriy Linikov. + - STM32, STM32L4 1WIRE: Added one bit read and write to 1-wire + interface. This is needed for devices that require single bit + timeslot generation and for 1-Wire search algorithm triplets. From + Juha Niskanen. + - STM32 F3 SPI: Enable DMA for SPI on stm32f30xxx MCUs. From Michal + Lyszczek. + - STM32 L4 1WIRE: Ported 1wire driver from STM32.

Also makes the RTC + lowerhalf more like in STM32L4. From Juha Niskanen. + - STM32 F7 ADC/I2C/SPI: Added PM hooks to ADC, I2C and SPI. From + Juha Niskanen. + + * STMicro STM32 Boards: + + - Indium-F7: Removed support for the Indium-F7 board. This was done + for two reasons: (1) The board support was just clone of the + Nucleo-144 board support with naming changes. There has been no + support and no further development for the board support. (2) There + does not seem to be any available Indium-F7 board available to the + public anywhere on the Internet. There is not even a reference to + the board on the rafresearch.com web stie. + - Nucleo-L452RE: Added buttons example From Juha Niskanen. + - Nucleo-L476RG: Added support to Nokia LCD PCD8544 on nucleo-l476rg. + From Alan Carvalho de Assis. + - Nucleo-L476RG: Added nxdemo configuration to nucleo-l476rg using + PCD8544. From Alan Carvalho de Assis. + - Olimex-STM32-P407: Added a zmodem test configuration. + - Olimex-STM32-P407: Added the module configuration. + - Photon: Added RGB led support From Anthony Merlino. + - STM32F103-Minimum: Added support for DFU bootloader From Simon + Piriou. + - Spark: Removes Spark board configuration. Still available in the + Obsoleted repository. If there is no CC3000 support, then there is + no purpose in supporting the Spark either. + - STM32F334-Disco: Added buck/boost converter example configuration. + From Mateusz Szafoni. + - STM32F4 Discovery: Added support for multiple MAX31855 sensors to the + STM32F4 Discovery From Tiago Almeida. + - STM32F4 Discovery: Added support in bring-up logic to initialize the + HCI UART and register the HCI UART network device. + - STM32F4 Discovery: Added MAX7219 support to STM32F4Discovery board. + From Alan Carvalho de Assis. + - STM32F4 Discovery: Added board configuration for CS43L22 audio + example.

From Ivan Ucherdzhiev. + + * TI TMS570 Boards: + + - configs/tms570ls31x-usb-kit: Added support for the TI Hercules + TMS570LS31x USB Kit From Ivan Ucherdzhiev. + + * TI Tiva: + + - CC3200: Remove all support for the CC3200. This was a port that was + started but never completed. What good is partial CC3200 support + with no wireless support?. + + * TI Tiva Drivers: + + - EEPROM: Implements an EEPROM driver in compliance with MTD driver + as provided by NUTTX for TM4C1294. The EEPROM driver currently + supports only two functionalities - read bytes(multiple of 4) and + write bytes (multiple of 4). From Shirshak Sengupta. + - FLASH: Implemented Flash CONFIG_MTD_BYTE_WRITE for TM4c1294. + Implemented the tiva_write function which will write an arbitrary + number of bytes to flash (in multiple of 4). From Shirshak Sengupta. + - Serial: Added TERMIOS IOCTL support to the Tiva serial driver. + From Dmitry Sharihin. + + * TI Tiva Boards: + + - CC3200-Launchpad: Remove all support for the CC3200-Launchpad. + This was a port that was started but never completed. What good is + partial CC3200-Launchpad board support with no wireless support?. + + * Libraries/Header Files: + + - libs/: Moved all of the libraries under a common directory called + libs/ (libc, libnx, and libxx). This almost certainly break libcxx + for now. + - libs/libc/time: Added an implementation of clock(). + - libs/libc/lzf: Added a modified version of Marc Alexander Lehmann's + LIBLZF3.6 library From Boris Astardzhiev. + - libs/libc/unistd: Initial, minimal implementation of sysconf(). + Only sufficient to support the functionality of less standard + getdtabilesize(). From Michael Jung. + - libs/libdsp: Added DSP support library. From Mateusz Szafoni. + - include/sys: Added resource.h. + - include/nuttx/video: Add overlay support to framebuffer interface + definition. From Marco Krahl. + + * Tools: + + - tools/gencromfs.c: Added tools/gencromfs.c, a tool that can be used + to generate CROMFS file system images. + - tools/mkromfsimg.sh: Include an option in mkromfsimg.sh to ignore + FAT/RAMDISK. This permits you to build tiny systems with ROMFS but + with the rather large FAT FS support. From Alan Carvalho de Assis. + - tools/nxstyle.c: Added check for blank lines before and after single + line comments. From Bob Feretich. + - tools/sethost.sh: Added support for macOS. + - tools/uncrustify.cfg: An initial cut at an uncrustify C formatting + script from Gregory Nutt. Updated, corrected, and verified. From + Bob Feretich. + + * Build System: + + - Makefile: Added support for nconfig frontend for 'make nconfig'. + From Michal Lyszczek. + - configs/: Added definition of strip to many Make.defs files. + - staging/: Remove fixed lib/ subdirectory and its content. Replace + with new directory called staging/ that is created dynamically when + building and removed when 'make clean' is done. This both improves + the naming and eliminates a garbage directory from the repository. + - tools/: Move all build-related files (except the top-level Makefile) + into the tools/ sub-directory. This really cleans up the top-level + directory. + + * NSH: apps/nshlib: + + - apps/nshlib: Added the mkfatfs -r option which can be used to + specify the number of entries in the FAT12/FAT16 root directory. + From Boris Astardzhiev. + + * Examples/Tests: apps/examples: + + - apps/examples/adxl372_test and lxm330spi_test: Added ADXL372 and + LSM330 tests. From Bob Feretich. + - apps/examples/cc3000: Removed the CC3000 example. From Alan + Carvalho de Assis. + - apps/examples/cromfs: Added an example of how to build a CROMFS + file system image. + - apps/examples/elf: Extend the ELF program module demo so that you + can use compressed ELF programs with CROMFS. + - apps/examples/elf: Use strip command to make ELF binaries MUCH + smaller. Added an option to strip debug symbols even if the debug + symbols are enabled in the base code. + - apps/examples/max31855: Added an example to read multiple max31855 + sensors. From Tiago Almeida. + - apps/examples/netloop: Update network loopback example so that it + can be used to test TCP KeepAlive. + - apps/examples/nxdemo: Added nxdemo application From Alan Carvalho + de Assis. + - apps/examples/powerled: Added arch initialization. + - apps/examples/uavcan: Removed because apps/canutils/libuavcan is no + longer available. + + * System Utilities: apps/system + + - apps/system/lzf: Added the test case from Marc Alexander Lehmann's + LIBLZF3.6 librrary From Boris Astardzhiev. + - apps/system/embedlog: Support for embedlog data loggin package from + https://embedlog.kurwinet.pl/ From Michal Lyszczek. + - apps/system/zmodem: Added an option to enable hardware flow control + via termios. Allow stack size and priority to be configured. + - apps/system/zmodem: Call tcflush() before closing the serial port. + This is necessary because that close operation may hang if hardware + flow control is enabled. Consider this scenario: After the host + sz runs on the host, it exits and leaves CTS high. The target rz + completes, and tries to close the serial port. But if there is + buffered Tx data, then the close will hang when it tries to drain + the buffered Tx data since there is no where it can go. tcflush() + discards the buffered data and permits the close to continue. + There is additional logic in nuttx/drivers/serial needed to work + with this. + + * CAN Utilities: apps/canutils: + + - apps/canutils/libuavcan. Removed! libuavcan has not built for a + year or so. The basic problem is that as NuttX advances, the old + frozen version of libuavcan has become absolute because it violates + the portable POSIX OS interface. No one is maintaining the port so + there is no alternative but to remove it. + + * Network Utilities: apps/netutils: + + - apps/netutils/tftpc: Modified the TFTP client functions to use a + data read/write callback instead of a file. This allows TFTP to + write to arbitrary destination (in my case, a MTD device - for + firmware update). Two new functions are introduced for this, named + tftpget_cb and tftpput_cb. They are just made of most of the + existing code. The previously existing tftpget/tftpput functions + are now wrappers on the new ones, with callbacks that read/write + from files, so my modifications are backwards compatible with + existing applications, eg the associated nsh commands dont need to + be changed. From Sebastien Lorquet. + + * Wireless Utilities: apps/wireless: + + - apps/wireless/bluetooth/btsak: Added a Bluetooth debug tool. + +Bugfixes. Only the most critical bugfixes are listed here (see the +ChangeLog for the complete list of bugfixes and for additional, more +detailed bugfix information): + + * Core OS: + + - sched/sched: Fix a deadlock in SMP mode. Two months ago, I + introduced sched_tasklist_lock() and sched_tasklist_unlock() to + protect tasklists in SMP mode. This change works well for HTTP + audio streaming aging test with lc823450-xgevk. However, I found a + deadlock in the scheduler when I tried similar aging tests with DVFS + autonomous mode where CPU clock speed changed based on cpu load. In + this case, call sequences were as follows. To avoid this deadlock, + I added sched_tasklist_unlock() when calling up_cpu_pause() and + sched_addreadytorun(). Also, added sched_tasklist_lock() after the + call. Also added critical sections to lib_filesem.c, mm_sem.c, and + net_lock.c for SMP for SMP. From Masayuki Ishikawa. + - sched/sched: Change ordering of round-robin time slice check + (sched_process_scheduler()) and processing of wdog timers + (wd_timer()). wd_timer()'s callback function can change current + running task and, hence, must be done after the time slice check. + The time slice check will decrement the currently running task's + time slice allotment. If such a context switch occurs, then the + newly started task will lost one could of that allotment before it + even has a chance to run. From EunBong Song. + + * File System/Block and MTD Drivers: + + - fs/fat: In fs_stat(), when stat'ing the root directory, avoid + calculating the address of the root directory entry. The + calculation is bogus (but not harmful) because the root directory + does not have a directory entry. Noted by Boris Astardzhiev. + - fs/fat: Avoid calculating the bogus directory entry address for + the FAT root directory (since it has no directory entry). This + change should have no effect, other than making the logic clearer. + From Boris Astardzhiev. + - fs/mount: Fix wrong size reported by df -h. Reason is that size + in bytes is calculated always on uint32_t types and cards bigger + than 4GB will overflow uint32_t type. Solution is to use uint64_t + where possible. From Michal Lyszczek. + - fs/smartfs: Fix a hardfault in SmartFS. Problem occurred when + opening a file with O_CREAT (only) when the file arelready exists + but has a size of zero. From Michal Lyszczek. + - fs/vfs: Fix negative errno set in fs_open.c From Michal Lyszczek. + - drivers/mtd: Fixed a W25 driver w25_cacheflush sector bug. From + lihaichen. + - drivers/mtd: mtdconfig_register() returned OK instead of -ENOMEM on + failed allocation. From Michal Lyszczek. + + * Graphics/Display Drivers: + + - drivers/lcd/ft80x: ACTIVE host command appears to be formatted + differently than other host commands; Fix ROM CHIPID. Appears to + be big-ending, BCD. Fix some compile issues when debug features + are enabled. + - drivers/lcd/ft80x: Fix a typo that caused the driver to fail to + recognize the ft801 chip version. From Gregory Nutt. + - Review all board implementations of board_lcd_initialize(). The + NuttX convention is that all internal functions that return errors + as an 'int' must return a negated errno value on failure and a non- + negative value on success. Most were right but eight of them had + cloned logic that returns 1 on success and zero on failure. both + of which are interpreted as success by the caller since they are + non-negative. + + * Networking/Network Drivers: + + - net/tcp: Fixed problem with send() retrun value when using + nonblocking I/O over buffered tcp socket From Dmitriy Linikov. + - net/sixlowpan: Fix a nasty, byte-ordering/endian-ness problem. + The root cause has been found and corrected. And a half dozen + or so bandaid fixes were reverted. + - net/sixlowpan: Preserve big-endian (network order) when + uncompressing address. From Anthony Merlino. + - net/sixlowpan: TCP send should have PSH and ACK flags set when + sending. This matches the standard network (Ethernet) TCP send + logic. From Anthony Merlino. + - net/udp: Fix several issues using connected UDP sockets: sendto() + should not accept an address. Normally send() should be used with + connect UDP sockets instead. recvfrom() is no longer necessary. + recvfrom() and poll() should not reset to accept any addresses but + should, instead, only accept inputs and events from the connected + remote peer. On of these issues was noted by ??? + . Changes were made as summarized here: + http://www.masterraghu.com/subjects/np/introduction/unix_network_programming_v1.3/ch08lev1sec11.html + From Gregory Nutt. + - net/udp: Resolve race condition in connection-less UDP sockets with + read-ahead buffering. In connection-mode UDP sockets, a remote + address is retained in the UDP connection structure. This + determines both there send() will send the packets and which packets + recv() will be accepted. This same mechanism is used for + connection-less UDP sendto: A temporary remote address is written + into the connection structure to support the sendto() operation. + That address persists until the next recvfrom() when it is reset to + accept any address. When UDP read-ahead buffering is enabled, + however, that means that the old, invalid remote address can be left + in the connection structure for some time. This can cause read- + ahead buffer to fail, dropping UDP packets. Shortening the time + between when he remote address is reset (i.e., immediately after the + sendto() completes) is not a solution, that does not eliminate the + race condition; in only makes it smaller. With this change, a flag + was added to the connection structure to indicate if the UDP socket + is in connection mode or if it is connection-less. This change + effects only UDP receive operations: The remote address in the UDP + connection is always ignored if the UDP socket is not in connection- + mode. No for connection-mode sockets, that remote address behaves as + before. But for connection-less sockets, it is only used by sendto(). + + * Wireless/Wireless Drivers: + + - drivers/wiresless/ieee80211: Correct some initialization problems + with BCM43362 chip. From hhuysqt. + - drivers/ieee802154/xbee: Added a timeout to send logic to handle + case where XBee module fails to respond to a Transmit request with + a Transmit Status From Anthony Merlino. + + * Common Drivers: + + - Per OpenGroup.org, syslog -- and, hence, nonstandard vsyslog, and + debug wrappers -- does not return a value. Rename _vsyslog to + nx_vsyslog. Use internal nx_vsyslog in the few cases where a + return value is required. + - drivers/leds: Fixes RGB LED issues caused by uninitialized memory + with CONFIG_RGBLED_MULTICHAN. The uninitialized pwm_info_s struct + caused a rogue channel to be started causing errors in the pwm + driver From Anthony Merlino. + - drivers/sensors/lis2dh: Clear INT1 at SNIOC_WRITE_INT1THRESHOLD + ioctl. From Jussi Kivilinna. + - drivers/sensors/sht21: Changed I2C_TRANSFER return value so that + it return on zero on success, not the count of bytes transferred. + From Juha Niskanen. + - drivers/serial: Per Matias Edlund: I recently used the tcflush + function and found that it failed with ENOTTY. The reason is that + the TCFLSH case in the function uart_ioctl in the file + drivers/serial/serial.c does not update the ret value." On + success, the TCFLSH IOCTL logic needs to explicitly set the return + value (ret) to zero. + - drivers/serial: Added a timeout to uart_tcdrain(). Even if + tcflush() is used to discard buffered data, the close() can still + hang if (a) hardware flow control is enabled, (b) CTS == 1, and + (c) there is data stuck in the hardware Tx FIFO. tcflush() does + not currently clear the MCU serial drivers' hardware Tx FIFOs. + This is a workaround for that. + - drivers/sensors: Fix APDS9960 work queue BUG found by Kyle Lei. + From Alan Carvalho de Assis. + + * Simulator: + + - arch/sim: Various fixes necessary to build the simulator under + MSYS2. + + * ARMv7-R: + + - ARMv7-R: Corrected several ARMv7-R issues. From Ivan Ucherdzhiev. + + * Infineon XMC4xxx Boards: + + - XMC4500-Relax: Call xmc4_spidev_initialize() in xmc4_boot.c. From + Alan Carvalho de Assis. + + * NXP/Freescale LPC17xx Drivers: + + - LPC17xx USB: Fix USB device endpoint allocation bookkeeping. From + Michael Jung. + - LPC17xx USB: Freeing endpoints should be set the same allocations + as when endpoint was allocated. + - LPC17xx USB: Fix loss of RX initiatives. USB bulk endpoints are + double buffered on LPC17xx MCUs. This means that up to two packets + might be received on an OUT endpoint that can not be handled + immediately if the receive request queue is empty. Thus, + rxpending must be a counter not a boolean flag. From Michael Jung. + + * NXP/Freescale Kinetis Drivers: + + - Kinetis USG: USB device fixes: Use correct CONFIG OTG control, + Fix interrupt storm when cable is disconnected. The DM, DP state + were incorrect because the pulldowns were not enabled. Also the + pending asynchronous resume interrupt needed to be re-armed after + the suspend is in effect. This is now done in the isr. From David + Sidrane. + - Kinetis Serial: In kinetis_lowputc.c, fix esBRFA calculation + effecting baudrate. Previous BRFA was not cleared and or-ed into + new BRFA, hence, buadrate was wrong. Where Baud Rate Fractional + Divisor (BRFD) UART baud rate = clock / (16 * (SBR + BRFD)). From + David Sidrane. + - Kinetis Serial: In kinetis_lowputc.c, fixed parity settings. + Kinetis UART must be placed in 9 bit mode (M=1) with when 8 bit data + with parity is required. If left in 8 bit mode (M=0) with parity + then D7 of the TX/RX register becomes parity bit. Hence what is + called 9-bit or 8-bit Mode Select is a misnomer. 8 bit mode when + parity is enabled is realy 7 bit with parity. From David Sidrane. + + * NXP/Freescale Kinetis Boards: + + - configs/teensy-3.x: Remove CONFIG_USBDEV_DUALSPEED from the usbnsh + configuration. Hardware supports only FS. + + * NXP i.MX6 Drivers: + + - i.MX6: Bring in a few i.MX6 fixes that were committed to similar + files for the i.MX RT. + + * STMicro STM32: + + - STM32 F3: Problem: stm32f30xx hangs waiting for LSE to initialize. + Reason for hang is that operation of setting LSE_ON does not take + effect because there is no clock on PWR peripheral. This is + initialized later in the code From Michal Lyszczek. + + * STMicro STM32 Drivers: + + - STM32 and STM32 L4 1WIRE: In 1wire driver, do not write useless + WRITEBIT zero return value to const buffer From Juha Niskanen. + - STM32 HRTIM: Fixed capture_get function,. From raiden00pl. + - STM32 F3 ADC: Fixed bug in RCC reset logic that resets ADC1 + configuration when both ADC1 and ADC2 are in use From Mateusz + Szafoni. + - STM32 Ethernet: In case of PHY failure, usually because of the + lack of 25/50 MHz REFCLK input, the Ethernet block would lock up + in a while loop waiting for readiness, which will never happened. + This prevented the board from starting at all in the case of a PHY + failure. This commit adds a retry loop to avoid bricking the board + if the Ethernet block is unable to start. From Sebastien Lorquet. + - STM32 F7 SDMMC: Added support for the second SDMMC device. The + second SDMMC device was already supported but the clock was never + enabled. This fixes that. From William Douglas. + - STM32 Serial: Fix UART glitch when lowputc is enabled. From + Simon Piriou. + - STM32 USB: Skip recipient check for descriptor related + requests From Simon Piriou. + + * TI Tiva Drivers: + + - Tiva ADC: Fix compilation errors on Tiva ADC code when ADC is + enable. From Vinicius Maciel. + - Tiva Serial: Allow building of Tiva platform with no serial + console. From Dmitry Sharihin. + + * C Library/Header Files: + + - lib/libc/netdb: Fixed boundary conditions in dns_recv_response(). + Fixed typos in include/nuttx/net/dns.h. From Masayuki Ishikawa. + - libs/libc/modlib: Fixed backward test for an error in + modlib_verify.c. + + * Build System: + + - Makefiles: Eliminate the spurious errors reported by 'make + savedefconfig'. + - Makefile(s): There is a sort command in the 'make savedefconfig' + file. I found that sort behaves differently on different platforms + based on the environment variable LC_ALL. Now, Makefile.unix will + force LC_ALL=C just for the sort command so that we can all generate + equivalent defconfig files. + - Makefile(s): The clean_context target needs to invoke a + corresponding clean_context target in the apps/Makefile in order to + remove linkages. From Gregory Nutt. + - LibTargets.mk, tools/Config.mk: Drop executable bit on installed + libraries. The rules to install libraries under lib/ were modified + to use mode 0644 instead of the default 0755. From Andrey Zabolotnyi. + + * Examples/Tests: apps/examples: + + - apps/examples/ft80x: Fix some size calculations. Added option to + disable primitive tests. just too boring to have to watch over and + over again. Fix a typo in backlight fade logic; Fix error in + formatted display light debug dump output. + - apps/examples/ft80x: Text is handled by the coprocessor and, hence, + must use RAM_CMD, not RAM_DL. + - apps/examples/ft80x: Fix some errors in co-processor demos. Correct + an error in the spinner demo. + - apps/examples/nsh and posix_spawn: Must not call exec_setsymtab() + directly. That is a non-POSIX internal OS interface. + - apps/examples/ostest: Do not call AIO test without + CONFIG_EXAMPLES_OSTEST_AIO From Juha Niskanen. + - apps/examples/smps: Fix typos in Kconfig. All power, voltage, + current values were strings with no default. I assume they should + be 'int' with what default?. + - apps/examples/smps: Fixes in some printf and in Kconfig From + Mateusz Szafoni. + - apps/system/zmodem: Fix Makefile.host. It was broken when zmodem.h + was moved to apps/include/system. Fix an incompatibility with the way + that CRCs are calculated. + + * System Utilities: apps/system: + + - apps/system: Applications should use the standard clock() interface, + not the internal NuttX clock_systimer() interface. + - apps/system/stackmonitor: Fix comparison between pointer and zero + character constant. From Juha Niskanen. + + * Network Utilities: apps/netutils: + + - apps/netutils/netlib: Various fixes needed to get a clean netlib + build with Bluetooth only. + + * Wireless Utilities: apps/wireless: + + - apps/wireless: Applications should use the standard clock() + interface, not the internal NuttX clock_systimer() interface. + +NuttX-7.26 Release Notes +------------------------ + +The 126th release of NuttX, Version 7.26, was made on September 8, 2018, +and is available for download from the Bitbucket.org website. Note +that release consists of two tarballs: nuttx-7.26.tar.gz and +apps-7.26.tar.gz. These are available from: + + https://bitbucket.org/nuttx/nuttx/downloads + https://bitbucket.org/nuttx/apps/downloads + +Both may be needed (see the top-level nuttx/README.txt file for build +information). + +Additional new features and extended functionality: + + * Core OS: + + - General: Eliminate use of the non-standard type systime_t and + replace it the equivalent, standard type clock_t From Gregory Nutt. + - General: Replace non critical PANIC with DEBUGPANIC to save the + code space From Xiang Xiao. + - General: Replace all ASSERT with DEBUGASSERT to save the code + space From Xiang Xiao. + - Initialization: Add option to mount block device for + INIT_FILEPATH case. From anchao. + - clock(): clock_systimer() is no longer a system interface. It has + been replaced with the equivalent, standard interface clock(). + Moved the implementation of clock() from the C library into the OS + core. This is necessary because it calls the (now) internal OS + function clock_systimer(). clock() is now accessed only via a + system call in certain configurations. From Gregory Nutt. + - clock Utilities: Move clock_timespec_[add|subtract] to + include/nuttx/clock.h From Xiang Xiao. + - Binary Loader: Add binfmt_initialize(). All binary formats are + now registered centrally vs. in board-specific logic. This + simplifies the usage of the binfmt subsystem. From Xiang Xiao. + - Binary Loader: Reference default symtab name to binfmt From anchao. + - mm: Add mm_heapmember function and reimplement kmm_heapmember base + on mm_heapmember since this function is very useful if multiple + heaps exist. From Xiang Xiao. + - mm: Add {kumm/kmm}_calloc API. Add calloc API for manage user + memory and kernel memory in Flat Build/Kernel Build without kernel + heap. From zhuyanlin. + - pthreads: Add support static pthread stack. Add standard + pthread_attr_setstack() and pthread_attr_getstack(). In all cases + where the stack is released, add check to see which allocator must + be used to free the stack: The user or the kernel allocator. From + xuanlin. + - Semaphores: Apply the semaphore wait function + nxsem_wait_uninterruptible(). This function is a wrapped version + of nxsem_wait() that is uninterruptible and convenient for use. + From liuhaiyang. + - Signals: Add default signal action to SIGKILL. From ligd. + - Signals: Update the signal default action logic to support + sigaction(). signaction() must be able to handle and input action + of SIG_DFL to setup the default signal action; it mast also return + SIG_DFL it is replacing the default action. From Gregory Nutt. + - Signals: Default Signal Actions. Change some types to + superficially simplify. Add configuration options to enabled + default signal behaviors on a per-signal basis. I don't think + users are prepared for SIGALRM to terminate the task (which is the + correct default behavior if you don't change it). Extend the + implementation of default signals so that it is totally table + driven and extensible by simply mondifying the content of const + tables. From Gregory Nutt. + - Signals: Add support for SIGINT in addition to SIGKILL. + - Signals: Add logic and an interface to determine if a signal can + be caught or ignored. sigaction now correctly returns EINVAL on + any attempt to catch or ignore such signals (only SIGKILL for now + and only if CONFIG_SIG_DEFAULT=y). From Gregory Nutt. + - Signals: Add support for default signal actions for SIGSTOP, + SIGSTP, and SIGCONT. Add procfs support to show stopped tasks. + From Gregory Nutt. + - Signals: Add nxsig_action() to solve a chicken and egg problem: + We needed to use sigaction to set default actions, but sigaction() + would refuse to set actions if the default actions could not be + caught or ignored. From Gregory Nutt. + - Signals: Add configuration option to selectively enabled/disable + default signal actions for SIGSTOP/SIGSTP/SIGCONT and SIGKILL/SIGINT. + - Signals: If a task/thread was already blocked when + SIGSTOP/SIGSTP was received, it will restart in the running state. + It will appear that to the task/thread that the blocked condition + was interrupt by a signal and returns the EINTR error. From + Gregory Nutt. + - Signals: Update signal default STOP action. If waitpid was + called with the WUNTRACED then wake up waitpid(). From Gregory + Nutt. + - IRQs: Monitor the IRQ execution time. This is very useful for + measuring the interrupt latency. From Xiang Xiao. + - IRQ Dispatch: Add support interrupt chains in NuttX. IRQ chain is + very useful in these cases: (1) Multiple hardware connect to the + same request line(e.g. PCI), (2) Need multiple driver to support + one hardware block (like Linux MFD) From zhuguangqing. + - Work Queue: Modify high priority work queue to support multiple + threads. From ligd. + - System Calls: Add support for getpeername() and get_sockname() + system calls. From Gregory Nutt. + - System Calls: svcall/sycall logic needs to get the ucontext + argument from R4 instead of stack since all syscall parameters pass + from registers in syscall.h From Xiang Xiao. + - CPU Load Measurement: Support the CPU load measurement using + timer_lowerhalf_s interface From Xiang Xiao. + - Assertions: Change CONFIG_BOARD_RESET_ON_CRASH to + CONFIG_BOARD_RESET_ON_ASSERT, arch/: Implement call to + board_reset() if in all implementations of up_assert() when + CONFIG_BOARD_RESET_ON_ASSERT=y. From Xiang Xiao. + - boardctl(): Add support for board_app_finalinitialize() From ligd. + - Architecture Interface: Add prototype for an architecture-specific + up_trigger_irq function. From dongjianli. + - Architecture Interface: Add the garbage collection hook so each + architecture can do custom memory cleanup if necessary. From Xiang + Xiao. + - Architecture Interface: Add architecture-specific prototypes for + conversions between physical and virtual address. From ligd. + + * File Systems/Block and MTD Drivers + + - ProcFS: Add support for a procfs entry that will permit examining + the environment of any task. From Gregory Nutt. + - ProcFS: Add support for proc/self/, a convenient way for getting + information about the currently running task. From Gregory Nutt. + - HostFS: Add support for open() append mode From anchao. + - HostFS: Add ftruncate support. From Xiang Xiao. + - HostFS: Remove ARCH_SIM dependence since other architectures + (e.g., arm semihosting) could support hostfs too From Xiang Xiao. + - HostFS: Support remote directory names without a trailing '/' + From ligd. + - HostFS: Add re-try when hostfs mount() fails From ligd. + - NFS: Update NFS client mount to VER3 From zhangyuan7. + - Partitions: Add PTABLE parser fs/partion: Add a partition parser + framework fs/driver/fs_blockpartition.c: Add + register_blockpartition for block partition From Xiang Xiao. + - MTD: Add gd25 driver From wangyanjiong. + - MTD: In MTD partitions, copy the partition name to internal + buffer so that the caller can free the name argument From Xiang + Xiao. + - MTD: Support initialization of an FTL block device with a custom + name From Xiang Xiao. + - MTD: FTL: Reduce size of stack buffer from 64 to a maximum size + as determined from NAME_MAX. From Gregory Nutt. + - VFS poll(): Send poll() notification when the Tx buffer is flushed + From ligd. + - VFS fstat(): Add file_fstat() function for internal OS use. From + ligd. + - VFS fcntl(): Add file_fcntl, psock_fcntl, and psock_dupsd for use + within the kernel. From Xiang Xiao. + - VFS dup2(): Addpsock_dupsd for use within the kernel. From Xiang + Xiao. + - VFS poll(): Add poll use in kernel space. From dongjianli. + - VFS select(): Make select be more consistent with Linux man page: + 'The timeout ... Some code calls select() with all three sets + empty, nfds zero, and a non-NULL timeout as a fairly portable way + to sleep with subsecond precision.' From anchao. + + * Networking/Network Drivers: + + - Sockets: Add getpeername() support From ligd. + - sockopt(): Move psock check from [get|set]sockopt to + psock_[get|set]sockopt From Xiang Xiao. + - getsockname(): Add psock_getsockname function From Xiang Xiao. + - Netlink Sockets: This brings in a fragmentary, experimental + implementation of NETLINK sockets. There is not too much to that + socket support on this initial commit, just the netlink socket + framework. However, I decided to bring it into master because + there is a enough that I would not want to lose what is in place. + And since it is dependent on CONFIG_EXPERIMENTAL, its presence on + master should be innocuous. From Gregory Nutt. + - Interface Indexes: Add driver interface index support. Add + implementation of if_nametoindex() and if indextoname(). Raw + AF_PACKET sockets now depend on CONFIG_NETDEV_IFINDEX. Add syscall + support for if_nametoindex() and if_indextoname(). Includes an + algorithm to prevent an interface index from being reused until all + network interfaces have by assigned once. The prevents removable + devices from being removed, unregistered and re-installed, + re-registered and keeping the same interface index. From Gregory + Nutt. + - Driver Interface: Add devif_loopback() to check the loopback + case where a packet is being sent to itself. Modify the net driver + to call this function in this case. This function will simply + re-inject the packet back into the network and the network driver + will not put anything on the wire. From Xiang Xiao. + - Network Devices: Remove all references to CONFIG_NET_USER_DEVFMT. + That feature is now unconditionally enabled. This was done because + (1) the feature does not require very much additional memory, and + (2) it causes confusion in the configuration due to the additional + complexity. Any network drivers that fail to zero the device + structure interface name field (d_ifname) because calling + netdev_register() will, however, get a nasty surprise. From + Gregory Nutt. + - Network Devices: Add support for Microchip LAN91C111 driver From + Xiang Xiao. + - Network Devices: netdev_findby_ipv[4|6]addr return + netdev_default() as last resort but don't return loopback device + if another network device is in the UP state. From Xiang Xiao. + - Network Device IOCTLs: Add si_ioctl callback and net_ioctl_arglen + so usrsock could forward the ioctl to the remote end/ From + dongjianli. + - IPv6: Rename g_ipv6_allzeroaddress with the more meaning + g_ipv6_unspecaddr since the all-zero address is the IPv6 + unspecified address (sometime IN6_ADDR_ANY). Replace more inline + tests for IPv6 multicast with common net_is_addr_mcast() macro. + From Gregory Nutt. + - ARP: arp_find() now checks if the target IP belongs to one of the + local network devices. From Xiang Xiao. + - ARP: Make the function arp_find() thread-safe. It now returns a + copy of the MAC address from the ARP table entry, rather than a + potentially unstable reference to the ARP table entry. From + Gregory Nutt. + - TCP: Re-work of TCP receive window size algorithm. The new logic + is based only on the ability to buffer TCP read-ahead data. From + Gregory Nutt. + - UDP: Add support for the UDP_BINDTODEVICE protocol socket option + From Sebastien Lorquet. + - Slip: Uncomment the prompt of NET_SLIP_PKTSIZE in Kconfig file. + From Xiang Xiao. + - USRSOCK: Combine some the duplicated logic. From Xiang Xiao. + - USRSOCK: Optimize option dependence From Xiang Xiao. + - USRSOCK: Add the listen/accept/getpeername/ioctl support From + dongjianli. + + * Other Common Device Drivers: + + - Analog DAC: Add driver for digital to analog converter DAC7571. + Nucleo-L422KC: Add support for a connect DAC7571 converter. From + Daniel Pereira Carvalho. + - Audio Interface: Change member samp of apb to pointer so driver + can customize sample buffer allocation From ZhongAn. + - Audio Interface: Add ioctl cmd 'AUDIOIOC_SETBUFFERINFO' so user + space could config the buffer From ZhongAn. + - Audio Interface: Add hardware format support From anchao. + - I2S Interface: Add i2s_rxchannels and i2s_txchannels methods to + the I2S lower half interface. From ZhongAn. + - Audio: Move the I2S character driver to a dedicated folder. From + Xiang Xiao. + - Audio: Add audio_i2s device driver. From ZhongAn. + - Audio: Add the composite audio driver From Xiang Xiao. + - Crypto: Move dev_urandom.c into new crypto folder. From Xiang + Xiao. + - GPIO driver: Add gpio_pin_unregister function to GPIO driver + driver/ioexpander: Add pinset struct to GPIO driver for interrupt + pins larger than 64. Initialize pintype/inttype when registering + ioexpander device. Add SETPINTYPE ioctl command to the GPIO + driver. From zhuyanlin. + - I2C Interface: Add a definition to distinguish a new START of + messages from a repeated start. No lower-half I2C drivers actually + implement this new flag bit, however. In I2C write/read logic use + new repeated START definition where appropriate. Rename + I2C_M_NORESTART to I2C_M_NOSTART since it may be used in other + contexts than a repeated start. Add comments to clarify setup for + repeated start. From Gregory Nutt. + - I2C: Add the standard speed macros. From dongjiuzhu. + - Leds: Add support to MAX7219 to control 7-segment displays. From + Alan Carvalho de Assis. + - Power: PM: Add pm_stay and pm_relax function so special apps(e.g. + mediaplayer) could disable suspend during playback much like linux + kernel counterpart From Xiang Xiao. + - Power: PM: Add pm_querystate function From zhuguangqing. + - Power: PM: Don't update the power state in work thread: (1) + Simplify the code logic and remove the work queue dependence, (2) + Power calculation is too simple to delay into the work queue From + Xiang Xiao. + - Power: PM: Decrease the power state in the reverse order. Since + the child driver need power off before parent driver. From + zhuguangqing. + - Power: PM: Make power manager service available as soon as + possible: (1) Initialize g_pmglobals at the definition, (2) skip + hold the lock if OS isn't ready From Xiang Xiao. + - Power: PM: Add PM_RESTORE to notify driver that device exit WFI + so the driver could restore state. For example, WDT may stop + counting before enter low power state and restore the counting + again in PM_RESTORE notification From zhuguangqing. + - Power: PM: Add timer to decrease PM level automatically. From + ligd. + - PTYs: Add support so that a PTY can poll for both IN/OUT event + simultaneously. From ligd. + - PWM: Move pwm.c into pwm folder From Xiang Xiao. + - RTC Interface: Extend struct rtc_time by adding. From Xiang + Xiao. tm_nsec if RTC supports hiresolution time. From Xiang Xiao. + - Sensors: Add support for Telair T6713 carbon dioxide sensor. From + Juha Niskanen. + - Sensors: Add support for LSM303AGR and LSM6DSL sensors From + DisruptiveNL. + - Sensors: Add driver for DHTxx sensor. From Ouss4. + - syslog: Enable a partial, crippled version of syslog_flush(); + Call syslog_flush() from assertion handling logic of all + architectures. From Gregory Nutt. + - syslog: Channel configuration. Decouple SYSLOG_SERIAL_CONSOLE and + ARCH_LOWPUTC. Since some hardware can output log to the special + debug channel not serial. From anchao. + - syslog: Support pre-pending a prefix string to log output if + enabled. This very useful to identify which CPU send out the log + in AMP SoC. From anchao. + - Serial: Add Ctrl-C/Ctrl-X support. From ligd. + - Serial: Support UART direct write for non console device From + xuanlin. + - Serial: It is no longer necessary to restrict Ctrl-C handling to + the FLAT build sched/signal: Add a new configuration option to + select signal default actions, separate handling of signal default + actions from both task startup logic and from the serial TTY + Ctrl-C logic. Add a signal set in the group structure to keep + track of what signals have been set to the default action. In + dispatching signals in PROTECTED or KERNEL mode, use this signal + set to determine if the default signal handler is attached and + dispatch the signal in kernel mode for the default actions. From + Gregory Nutt. + - Serial: Integrate new Ctrl-C logic with the ISIG flag in the + termios c_lflag. From Gregory Nutt. + - Serial: Use SIGINT instead of SIGKILL when control-C is pressed. + From Gregory Nutt. + - Serial: Add support for Ctrl-Z. This works just like the + recently added Ctrl-C support except that SIGSTP is sent when the + Ctrl-Z characters is encountered vs. SIGINT. From Gregory Nutt. + - 16550 UART: Add a configuration, analogous to the STM32 + configuration option, to suppress the NuttX standard re-ordering + for /dev/ttySN for special case of the 16550 UART. + - 16550 UART: Add CONFIG_SERIAL_UART_ARCH_MMIO option so the a + memory mapped device doesn't need to provide uart_getreg() and + uart_putreg() implementations. + - 16550 UART: Add stub implementations of DMA-related methods in the + 16550 UART v-table. From ligd. + - 16550 UART: Add serial termios handling From anchao. + - 16550 UART: Support 16550 auto hardware flow control + drivers/serial/uart_16550.c: Add configuration option + CONFIG_16550_SUPRESS_INITIAL_CONFIG. This is identical to the + standard configuration in arch/Kconfig + CONFIG_SUPPRESS_UART_CONFIG, but with scope of only the 16550 + driver. From Xiang Xiao. + - syslog: Make timestamp output same as linux kernel. It's very + useful if NuttX syslog retarget to Linux syslog. From Xiang Xiao. + - Timers: Add maxtimeout method to the struct timer_ops_s interface + From Xiang Xiao. + - Timers: Add a new method to the struct oneshot_operations_s + interface to get the current time from a oneshot timer driver (if + it is available from the lower half) From Xiang Xiao. + - Timers: Implement timer arch API on top of timer driver. From + Xiang Xiao. + - Timers: Implement alarm arch API on top of oneshot driver + interface. From Xiang Xiao. + - Timers: Implement RTC arch API on top of RTC driver interface. + From Xiang Xiao. + - CDC/ECM: Adds USB device support for CDC/ECM From Michael Jung. + - USB Host: Add support for the Maxim M3421E USB host driver. Not + yet fully tested. From Gregory Nutt. + + * General Architecture-Specific: + + - All architectures: Make sure the up_irq_enable() is available on + all architectures. From Gregory Nutt. + + * Simulation + + - Simulator Configurations: Add dsptest configuration. From Mateusz + Szafoni. + - Simulator: In network driver (1) Remove up_comparemac() check for + matching MAC address. Let's trust that the tap device just return + the packet which belong to us like other real network device + hardware. (2) Add network device statistics support. From Xiang Xiao. + + * ARM: + + - ARM (all): Add CONFIG_DEBUG_MEMFAULT to Kconfig. From Masayuki + Ishikawa. + - ARM: (1) Add semihost support for syslog, (2) Add semihost support + for HostFS From Gregory Nutt. + + * ARMv6-M: + + - ARMv6-M: Introduce CONFIG_DEBUG_HARDFAULT_INFO to up_hardfault.c + From Masayuki Ishikawa. + + * ARMv7-M: + + - ARMv7-M: Removes support for the dedicated vector handling from the + many older architectures. Only common vectors are now supported. + From Gregory Nutt. + - ARMv7-M: Introduce CONFIG_DEBUG_HARDFAULT_INFO to up_hardfault.c + From Masayuki Ishikawa. + - ARMv7-M: Implement SYSTICK timer driver From Xiang Xiao. + - Simulator: Add loadable demo for arch sim. From anchao. + - ARMv7-M: Add logic to trigger ARMv7-M interrupts and exceptions. + From Gregory Nutt (from sample logic by Xiang Xiao). + - ARMv7-M: Add NVIC definitions needed by up_trigger_irq(). From + Gregory Nutt. + + * ARMv7-R: + + - ARMv7-R: Add general interrupt controller. This is based on + ARMv7-A gic controller code. From EunBong Song. + - ARMv7-R: Add invalidate dcache in arm_head.S. From EunBong Song. + + * Infineon XMC4xxx Drivers: + + - XMC4 GPIO: Add a specific bit encoding to GPIO driver for + opendrain GPIO pin. From Alan Carvalho de Assis. + + * Infineon XMC4xxx Boards: + + - XMC4500-Relax: Add support to MAX6675 on XMC4500-Relax board. + From Alan Carvalho de Assis. + + * Microchip PIC32MX Boards; + + - PIC32MX: Update some PIC32MX configurations so that either the + MPLAB or Penguino toolchains may be used. From Gregory Nutt. + + * Microchip/Atmel SAMD2x/L2x: + + - SAMD2x/L2x: Rename all usage of samdl/SAMDL to samd2l2/SAMD2L2 to + make room in the name space for samd5e5/SAMD5E5 From Gregory Nutt. + + * Microchip/Atmel SAMD5x/E5x: + + - SAMD5x/E5: Add a port to the SAMD5x/E5x MCU family. From Gregory + Nutt. + + * Microchip/Atmel SAMD5x/E5x Drivers: + + - SAMD5x/E5x SPI/I2C: Bring in untested SPI and I2C drivers from + SAMD2L2. From Gregory Nutt. + - SAMD5x/E5x DMA: Leverage the SAMD2L2 DMA controller. From Gregory + Nutt. + - SAMD5x/E5x USB: Bring the SAMDL2 USB driver into the SAMD5E5 + port. From Gregory Nutt. + + * Microchip/Atmel SAMD5x/E5x Boards: + + - Metro M4: Add support for the Adafruit Metro M4 board. From + Gregory Nutt. + - Metro M4: Add an option to build the Metro M4 image to run out of + SRAM. This ought to be a safer and quicker way to do the initial + bring-up (having bricked the first Metro M4 due to a bad FLASH + image). From Gregory Nutt. + - Metro M4: Add a configuration option to use OSCULP32K instead of + XOSC32K. From Gregory Nutt. + - Metro M4: After some final fixes related to the SERCOM console, + the basic NSH configuration appears fully functional. From + Gregory Nutt. + - Metro M4: Verify the CMCC and enable it by default in the NSH + configuration. From Gregory Nutt. + + * Microchip/Atmel SAMv7 Drivers: + + - SAMv7 CAN: Add ability for CAN BUS_OFF autorecovery according + ISO11898-1:2015. With this change we added an ioctl for triggering + the autorecovery sequence for BUS_OFF to the CAN-driver and the + SAMV7 low-level driver. According the datasheet: If the device + goes Bus_Off, it will set MCAN_CCCR.INIT of its own accord, + stopping all bus activities. Once MCAN_CCCR.INIT has been cleared + by the processor (application), the device will then wait for 129 + occurrences of Bus Idle (129 * 11 consecutive recessive bits) + before resuming normal operation. At the end of the Bus_Off + recovery sequence, the Error Management Counters will be reset. + During the waiting time after the resetting of MCAN_CCCR.INIT, each + time a sequence of 11 recessive bits has been monitored, a Bit0 + Error code is written to MCAN_PSR.LEC, enabling the processor to + readily check up whether the CAN bus is stuck at dominant or + continuously disturbed and to monitor the Bus_Off recovery + sequence. MCAN_ECR.REC is used to count these sequences. From + Frank Benkert. + + * NXP Freescale i.MX RT Drivers: + + - i.MXRT RTC: Add support for the i.MXRT RTC. This is code complete + (with limited features and options) but untested. The HPRTC is + functional. However, if the LPSRTC is enabled, then there is a + hang during LPSRTC initialization. It appears that there is some + problem in providing clocking and initializing the LPSRTC domain. + From Gregory Nutt. + - i.MXRT SNVS: Add trivial SNVS from Rev 1. of the Reference Manual. + From Gregory Nutt. + - i.MXRT LSPI: IMXRT1050 LPSPI register and bit definitions added. + From Ivan Ucherdzhiev. + - i.MXRT Serial: IMXRT1050 LPUART TERMIOS support added. From Ivan + Ucherdzhiev. + + * NXP Freescale i.MX RT Boards: + + - IMXRT1050-EVK: Add knsh configuration. PROTECTED mode NSH build. + From Gregory Nutt. + + * NXP Freescale Kinetis: + + - Kinetis: Add DMA support. From David Sidrane. + + * NXP Freescale Kinetis Drivers: + + - Kinetis: Use circular DMA as an option to augment the RX FIFOs in + the Serial driver. From David Sidrane. + + * NXP LPC54xx: + + - LPC54xx: The LPC54608 can only run at a maximum frequency of + 180Mhz. This configuration requires uses the clk_in, external + crystal clock, to drive the PLL. When that input was selected, the + board bootup failed waiting for the PLL to lock. After referring + the driver from NXP, we should turn on power sources for the ext + clock if system pll input select clk_in. NOTE that the LPC54628 + did not require this step... perhaps because the system oscillator + power was already enabled. From kxjiang. + - LC823450: Add support for mpu and userspace LC823450-XGEVK: Add + kostest PROTECTED build LC823450-XGEVK: Add knsh PROTECTED build + From Masayuki Ishikawa. + + * NXP LPC54xx Boards: + + - Lpcxpresso-LPC54628: Update lvgl board config to use the new + version From Alan Carvalho de Assis. + + * On Semi LPC23450 Drivers: + + - LC823450 Bluetooth: Add lc823450 Bluetooth support. From Masayuki + Ishikawa. + - LC823450 I2S: Add tx start threshold to lc823450_i2s.c In + addition, lc823450_i2s_send() now accepts byte-aligned stream. + From Masayuki Ishikawa. + - LC823450 SPI: Add SPI flash driver for lc823450. NOTE: Only bus + accelerator mode is supported. From Masayuki Ishikawa. + - LC823450: Change C-Buffer under-level control. The under-level + setting was changed from 1KB to 55KB. In previous implementation, + the setting can be changed by the tx threshold but it is fixed at + startup.

From Mateusz Szafoni. + - include/nuttx/compiler.h, include/poll.h: Add logic to determine + if the compiler supports anonymous structures and unions. From + Gregory Nutt. + - include/nuttx/mutex.h: Add inline wrapper functions to more + clearly support semaphores when used as mutexs. From QianWenfa. + - include/nuttx/nuttx.h: Added nuttx.h header file which is + analogous to the linux.h header file. Currently, it contains on + the definition of the container_of() macro. From zhuyanlin. + - include/queue.h: Add dq_tail marco From zhuguangqing. + - include/stdio.h: Add prototypes for popen() and pclose(). Actual + implementation is in apps/system/popen() From Gregory Nutt. + - include/sys/param.h: Add a dummy sys/param.h header file. This is + not a standard file but is used by other systems and having the + dummy file may minimize some porting efforts. From Gregory Nutt. + + * Tools: + + - nuttx/tools/kconfig2html.c: Due to new usage, tool needs to be + able to handle configuration files with names other than Kconfig. + From Gregory Nutt. + - nuttx/tools/kconfig2html.c: Update tool to handle tristate types. + From Gregory Nutt. + - nuttx/tools/Config.mk: Add function CATFILE definition. Currently + only used in apps/builtin/Makefile. From Gregory Nutt. + - nuttx/tools/Config.mk: Add the recursive wildcard function, + RWILDCARD, to Config.mk. From Gregory Nutt. + - nuttx/tools/testbuild.sh: Add an option to specify the location of + nuttx directory. From Gregory Nutt. + - nuttx/tools/refresh.sh: Add a --prompt option that will let you + use --silent but will prompt before overwriting the original + defconfig. From Gregory Nutt. + - nuttx/tools/link.sh. Update link.sh per suggestions by Mark so + that it can be used with MSYS vs copydir.sh. From Gregory Nutt. + - nuttx/tools/mkexport.sh: Save the System.map file and User.map + file (if it exists) in the export package so that it can be used to + extract addresses. From Gregory Nutt. + - nuttx/tools/mkexport.sh: Save the name of the STRIP tool too. From + Gregory Nutt. + - nuttx/tools/nxstyle.c: Add capability to detect multiple blank + lines. Single spacing required by the coding standard. Also coding + standard fixes to server .c files for problems found during testing + nxstyle. From Gregory Nutt. + - apps/tools: Add +x to mksymtab.sh. From Masayuki Ishikawa. + - apps/tools/define.sh and define.bat: Move a copy of define.bat + and sh from nuttx/tools to apps/tools so that they will be + available for the import build. From Gregory Nutt. + + * Build System: + + - Apps/ Build System. The apps/ build system has undergone a major + renovation to better support building applications as ELF modules. + Module selections have changed from 'bool' to 'tristate' types. + This means that building an ELF now is as simple setting the value + to 'm'. This effort required many changes, too many to summarize + here. The solution was contributed by Masayuki Ishikawa, Anchao + An, and Xiang Xiao (and myself to a lesser extent). + - NuttX/ Build System: This change extends support for the two-pass + build. Its primary purpose is to incorporate source logic + generated by applications into the kernel phase of the build. + In the two pass build, the application logic is built during the + first phase, pass 1. In that phase, the application may generate + and install source files in the pass1/directory. The operating + system is built during phase 2 of the build. At that time, those + source files in the pass1/ directory will be built and incorporated + into the kernel address space. + The primary purpose of the pass1/ directory is to such + application-generated kernel symbol tables. For an example of the + use of this feature, look at + apps/examples/module/drivers/Makefile. Kernel symbol tables are + needed to support kernel modules. Of course, addition + board-specific logic in, say, configs//src would have to be + included to make use of the application-installed symbol tables. + From Gregory Nutt. + - Remove CONFIG_ARCH_CALIBRATION. It is awkward to use and no longer + necessary now that we have apps/examples/calib_udelay. From + Gregory Nutt. + - Build System: With recent changes to apps/ all configurations that + build applications as modules must now also select + CONFIG_APPS_LOADABLE. From anchao. + - Build System: Add dynamic application loadable support. From + anchao. + - Build System: Add configuration CONFIG_ARCH_GNU_NO_WEAKFUNCTIONS + to suppress use of weak functions. Some gnu derived toolchains do + not support weak symbols. From Xiang Xiao. + - Kconfig: Move 'option modules' from NSH_FILE_APPS to + BUILD_LOADABLE From anchao. + - apps/ Build System: Introduce a build system for loadable apps + for nsh. Add 'option modules' to NSH_FILE_APPS so that a user can + change an application configuration to tristate (y/n/m) + - apps/import: Add Makefile.symtab which can be used to compile the + dynamically created symbol table C file. Also adds + tools/mksymtab.sh. From Gregory Nutt. + + * NSH: apps/nshlib: + + - apps/nshlib: Add parsing support for back-slash quoted + characters. Currently only implemented properly if + CONFIG_NSH_ARGCAT is also selected. This commit is in response to + Bitbucket Issue 11 opened by Maciej Wjcik From Gregory Nutt. + - apps/nshlib: Add inverted logic support in the form of 'if ! + ' From Beat Kng. + - apps/nshlib: Expand reboot and poweroff commands to include a + second, optional mode argument From ligd. + - apps/nshlib: Add a force flag (-f) to mksmartfs command. SmartFS + will be formatted only if (1) the FLASH does not already hold a + SmartFS, or (2) the force flag is set. From Xiang Xiao. + - apps/nshlib: NSH prompt string is now configurable. nsh> is + still the default. From Xiang Xiao. + - apps/nshlib: Add control-C support for terminating built-in and + exec'ed file tasks. From ligd. + - apps/nshlib: Call BOARDIOC_FINALINIT after start-up script (or + immediately after BOARIOC_INIT is there is no start-up script). + From ligd. + - apps/nshlib: When using waitpid() to wait for a built-in + application or a file application to exit. Add the WUNTRACED + options to so the the waitpid() call will also be awakened if the + waited-for task is stopped as well. From Gregory Nutt. + + * NSH Builtins: apps/builtin: + + - apps/builtin/Makefile. This commit changes apps/builtin to search + the registry recursively. By supporting directories, external + projects can install the hooks into the registry and easily clean + them up and reinstall if something needs to be updated. Based on + an idea from Anthony Merlino. From Gregory Nutt. + + * Examples/Tests: apps/examples: + + - apps/examples/calib_udelay: Add tool for calibrating + CONFIG_BOARD_LOOPSPERMSEC From Juha Niskanen. + - apps/examples/dhtxx: Example for the DHTxx sensor. From Ouss4. + - apps/examples/dsptest: Add unit test for Nuttx DSP library From + Mateusz Szafoni. + - apps/examples/elf: CROMFS and ROMFS configuration currently only + usable in FLAT build. Add configuration to use ELF objects on + external media like SD card or USB drive instead. From Gregory + Nutt. + - apps/examples/elf: If the test ELF files are on media in + removable media such as SD or USB FLASH, the wait until the media + has been installed and initialized before starting the test. From + Gregory Nutt. + - apps/examples/fb: Adds example to test framebuffer overlay From + Marco Krahl. + - apps/examples/gps: Add GPS example using MINMEA lib From Alan + Carvalho de Assis. + - apps/examples/i2sloop: Add i2sloop application. This application + can be used to test I2S loopback like: ' nsh> i2sloop &'. From + Masayuki Ishikawa. + - apps/examples/lvgldemo: Update LVGL to version 5.1.1 From Alan + Carvalho de Assis. + - apps/examples/module: Add support for CROMFS and for stripping + symbols from ELF module binaries. From Gregory Nutt. + - apps/examples/module: Add support for automounting removable media. + This involves a wait for the block driver to become available + before performing the mount. From Gregory Nutt. + - apps/examples/module: When built in the PROTECTED or KERNEL + modes, the symbol table is not built by the application. That is + because the build will fail since the kernel module depends on + internal OS symbols thar are not available to the application + build. With this change the examples does not attempt to build + the kernel symbol table in these modes. Instead it just copies + the kernel module symbol table into the nuttx/pass1 directory + where it can be build directly into the OS during pass2 of the + build. From Gregory Nutt. + - apps/examples/ostest: Add a small test for SIGSTOP, SIGCONT, and + SIGKILL actions. From Gregory Nutt. + - apps/examples/popen: Add a test of popen/pclose. From Gregory + Nutt. + - apps/examples/powerled: Add arch initialization. From Mateusz + Szafoni. + - apps/examples/tcpblaster: Add TCP performance measurement test. + From Gregory Nutt. + + * System Utilities: apps/system + + - apps/system/cle: Usage improvements including command line + history (taken from readline) and support for addition control + characters. From mst. + - apps/system/i2c: Adapt to rename I2C_M_RESTART->i2C_M_START. + I2C_M_NOSTOP should be in flags of first message in every + write-read and write-write mesage sequence. From Gregory Nutt. + - apps/system/i2c: Allow registers besides 0x00 in the dev command. + From Jakob Haufe. + - apps/system/nsh: Add logic to automatically register an + application symbol table as part of NSH initialization. From + Masayuki Ishikawa. + - apps/system/nsh: The symbol table name and size variable names + can now be configured. From Gregory Nutt. + - apps/system/nsh: Move apps/examples/nsh to apps/system/nsh. It + has become so entrenched that it is hardly an example these days. + May as well formalized it as a system task. From Gregory Nutt. + - apps/system/nxplayer: Refactor nxplayer.c. Apply + netlib_parsehttpurl() and + remove unnecessary usleep(). From Masayuki Ishikawa. + - apps/system/nxplayer: Release buffer before session and release + semaphore in nxplayer_setvolume system/nxplayer/nxplayer.c: + Remove & for apb->samp reference. It is already a pointer. From Xiang Xiao. + - system/nxplayer/nxplayer.c: Add playraw command From ZhongAn. + - apps/system/nxrecorder: Add nxrecorder application From ZhongAn. + - apps/system/popen: Add an implementation of the standard popen() + and pclose() OS interfaces. These are implemented as applications + vs. part of the OS because they depend on NSH. Untested on + initial commit. From Gregory Nutt. + - apps/system/system and popen: Adapt so that these can be used in + the KERNEL build mode. In this case, simply replace task_spawn() + with posix_spawn(). This depends on the existence of some + environment where /bin/sh exists and can be used to execute one + NSH command. For the case of system(), this change was more + complete because it previously used task_create(). Now it uses + either task_spawn() or posix_spawn(), depending upon the + configuration. From Gregory Nutt. + - apps/system/taskset: Add taskset command for SMP systems. This + command can be used to retrieve or set a process's CPU affinity. + For example, + + nsh> taskset -p 4 + pid 4's current affinity mask: 2 + + nsh> taskset -p 3 4 + pid 4's current affinity mask: 3 + + nsh> taskset -p 1 busyloop & + + From Masayuki Ishikawa. + - apps/system/zmodem: Support -p for rz to change the folder + for the received file. Switch debug output from printf to + syslog. Send the next packet for ZME_ACK in ZMS_SENDING to avoid + rz on the host side stuck make send work reliable even without + hardware flow control. From Xiang Xiao. + + * Network Utilities: apps/netutils: + + - apps/netutils/dhcpc: Activates BINDTODEVICE if available. From + Sebastien Lorquet. + + * Wireless Utilities: apps/wireless: + + - apps/wireless/i8sak: i8sak daemon now gets shutdown if not in use. + Previously, once the i8sak daemon was started, by running any + command, it would stay running. This means that if you want to use + i8sak to setup your network, but then want exclusive access to the + char device, or network device, you have to manually shutdown the + i8sak daemon. Now the daemon stays active as long as required to + finish any commands, or stays open if a new command keeps it on, + but when all work is finished, it shuts down. From Anthony Merlino. + + * Filesystem Utilities: apps/fsutils: + + - mkfatfs: Clean up some name BS_ and MBR_ refer to the same record + and should use the same naming (MBR_). From Gregory Nutt. + - mkfatfs: Add definitions for the FAT boot record (FBR). From + Gregory Nutt. + - mksmartfs: Add a check to see if the SmartFS is already + formatted. From Xiang Xiao. + + * Graphic Utilities: apps/graphics: + + - graphics/littlevg/: Update LVGL to version 5.1.1 From Alan + Carvalho de Assis. + + * Test Utilities: apps/testing: + + - testing/unity: Add Unity - unit testing library from + ThrowTheSwitch.org. From Mateusz Szafoni. + +Bugfixes. Only the most critical bugfixes are listed here (see the +ChangeLog for the complete list of bugfixes and for additional, more +detailed bugfix information): + + * Core OS: + + - Signals: Signal handlers maybe run with interrupts enabled or + disabled, depending on how the task the received the signal was + blocked. (i.e.: If sem_wait() is called, then we disable + interrupts, then block the currently running task). This could be + dangerous, because user code would be running with interrupts + disabled. + This change forces interrupts to be enabled in up_sigdeliver() + before executing the signal handler calling up_irq_enable() + explicitly. This is safe because, when we return to normal + execution, interrupts will be restored to their previous state when + the signal handler returns. From Gregory Nutt (Based on a + recommendation by Mark Shulte). + - Signals: Lock the scheduler while while killing the children so + that we do not lose priority and let the task group continue to + run in an indeterminate state. From Gregory Nutt. + - Groups: Fix a deadlock when loading an ELF From Masayuki Ishikawa. + - Groups: In some circumstances, group_killchildren() could have + called pthread_cancel() to kill a task. Also, the behavior would + not be as expected if a pthread had cancellation disabled. From Gregory Nutt. + - Posix Message Queues: mq_notify() fix - only part of struct copied + to internal structure. As source address the address of the struct + member sigev_value was used, and it is not located the start of the + struct. This leads to invalid data being copied to internal + structure. Both source and destination should be of type struct + sigevent* . From Simon Liedl. + - vfork(): vfork operation needs to allocate and copy the task + argument too. Also correction of the address correction cannot + depend on the stack pointer since it is not available in all + architectures. Rather calculate the offset from the stack + allocation pointer From Xiang Xiao. + - IRQ Dispatch: Ensure vector never points to NULL since interrupt + may happen before irq_initialize() From Xiang Xiao. + - Work Queue: workqueues don't need set global data to zero since + .bss is cleared automatically. Removing this unnecessary + initialization also avoids the loss the work items queued before + initialization. From ligd. + - Work Queue: Remove work queue polling delay to simplify the code + logic and save the power. From xuanlin. + - syslog: Fix syslog crash on 64bit simulation. From anchao. + - Pipes: Write to a pipe when there are no readers from the pipe + should return -EPIPE. From ligd. + - System Calls: Fix 6th parameter type of posix_spawnp in + syscall.csv From Masayuki Ishikawa. + - System Calls: Remove unused SYS_nnetsocket from syscall.h. Because + SYS_nnetsocket is not implemented so far, it should be removed so + that SYS_prctl can work correctly. From Masayuki Ishikawa. + - Binary Loader: Refactor binfmt_exec.c. This change also fixes an + argv issue for CONFIG_SCHED_ONEXIT=n or CONFIG_SCHED_HAVE_PARENT=n + From Masayuki Ishikawa. + - Binary Loader: Re-architect the way that loadable ELF or NXFLAT + modules are unloaded. Memory resources must be recovered when the + task loaded into memory exits. The original implementation used + the death-of-child SIGCHLD signal to perform the unload. There are + several problems with this: It is overly complex, it requires that + the parent task stay resident while the loaded task runs, and it + has fatal logic flaws in the protected and kernel model builds + because the user signal handler attempts to run in the kernel + address space. This corrects the issue using a mindlessly simply + BINFMT callback when the task exits. From Gregory Nutt. + - ELF Binary Loader: Set priority level to default if parent has no + priority. From anchao. + + * File System/Block and MTD Drivers: + + - Auto-mounter: Ignore return values from work_cancel(). From + Gregory Nutt. + - SmartFS: Fixed filesystem corruption when writing to small file + after open(... O_APPEND). From Dmitriy Linikov. + - SmartFS stat(): A previous change added support for checking if a + descriptor is a socket in fstat().' but it changed sys/stat.h in + way that breaks smartfs file-type stat flags. CROMFS is similarly + broken, as tools/gencromfs.c was not updated to match the + sys/stat.h changes. This commit fixes both issues. It probably is + not a good idea to use NuttX sys/stat.h bit-field values directly + in stored structure of filesystem. From Jussi Kivilinna. + - HostFS: Update duplicated definitions in HOSTFS that must match + NuttX values. From ligd. + - HostFS: Ensure f_type is equal to HOSTFS_MAGIC. From Xiang Xiao. + - ROMFS: Make romfs_devread32 more portable From anchao. + - TmpFS: Correct logic in tmpfs_ioctl() that extracts the priv state + structure from the file system structures. It was not getting the + right value and causing mmap() to fail. Noted by Jesse. From + Gregory Nutt. + - ProcFS network statistics: Was not handling the output correct for + the case of an IEEE 802.11 device. From Gregory Nutt. + - ProcFS IRQs: Fix occasional computation error when fracpart >= + 1000 From Xiang Xiao. + + * Networking/Network Drivers: + + - TAP/TUN: Fixed custom tun devname formatting. From Dmitriy Linikov. + - Network Drivers: This change attempts remove some long standard + confusion in naming and some actual problems that result from the + naming confusion. The basic problem is the standard MTU does not + include the size of the Ethernet header. For clarity, I changed + the naming of most things called MTU to PKTSIZE. For example, + CONFIG_NET_ETH_MTU is now CONFIG_NET_ETH_PKTSIZE. This makes the + user interface a little hostile. People think of an MTU of 1500 + bytes, but the corresponding packet is really 1514 bytes (including + the 14 byte Ethernet header). A more friendly solution would + configure the MTU (as before), but then derive the packet buffer + size by adding the MAC header length. Instead, we define the + packet buffer size then derive the MTU. + The MTU is not common currency in networking. On the wire, the + only real issue is the MSS which is derived from MTU by subtracting + the IP header and TCP header sizes (for the case of TCP). Now it + is derived for the PKTSIZE by subtracting the IP header, the TCP + header, and the MAC header sizes. So we should be all good and + without the recurring 14 byte error in MTU's and MSS's. From + Gregory Nutt. + - netdev: Fix.. Too many calls to net_unlock() From Gregory Nutt. + - IPv6: There are many different checks for IPv6 multicast + addresses. Most of the checks are different. RFC 3513 clearly + specifies how to detect an IPv6 multicast address: they should + begin with 0xffxx. I did not change some of the checks in + ipv6_input.c, however. In that file, the comments indicate that + the code should only pick of certain multicast address that begin + with 0xff02. From Gregory Nutt. + - ARP: Fix some backward logic in an if condition. From Gregory + Nutt. + - TCP Re-assembly: Rename CONFIG_TCP_REASSEMBLY to + CONFIG_IPv4_REASSEMBLY. Add some fixes to get a clean compile with + CONFIG_IPv4_REASSEMBLY enabled. There are several problems with + the current implementation: It is untested (and depends on + CONFIG_EXPERMIMENTAL). It uses some Ethernet specific definitions + (and depends on CONFIG_NET_ETHERNET). There is only a single + reassembly buffer. The last two issues prevent use of this feature + in any context where IPv4 packets may be reassembled for multiple + network devices concurrently). From Gregory Nutt. + - TCP: Set the default TCP MSS to the value required by RFC 879 and + never change it under any circumstance unless the remote host + requests a larger MSS via an option the TCP header. From Gregory + Nutt. + - TCP: Fix a deadlock condition that can occur when (1) all network + logic runs on a single work queue, (1) TCP write buffering is + enabled, and (2) we run out of IOBs. In this case, the TCP write + buffering logic was blocking on iob_alloc() with the network + locked. Since the network was locked, the device driver polls that + would provide take the write buffer data and release the IOBs could + not execute. This fixes the problem by unlocking the network lock + while waiting for the IOBs. From Gregory Nutt. + - TCP: Remove g_netstats.tcp.syndrop++ from tcp_data_event() From + Masayuki Ishikawa. + - TCP Monitor: Fix net unlock issue when tcp close. This bug could + leave the net locked. From zhangyuan7. + - UDP: When sending a broadcast (or multicast) packet do not attempt + to look up the device by the destination IP address. Rather, use + the locally bound address for these cases to select the correct + network device. From Gregory Nutt. + - UDP: Restore some legacy behavior that was lost with the + implementation of CONFIG_NET_UDP_BINDTODEVICE: If no device has a + local address when the broadcast packet is sent and the UDP socket + is not bound to a device, there select some arbitrary device. This + is certainly lunacy in the case where there are multiple network + devices registered because the wrong device will probably be + returned. It works find, however, for the legacy case where only a + single network device is registered. From Gregory Nutt. + - UDP: Fix for network byte-order issue when checking if an address + is a multicast address. From Jake Choy. + - USRSOCK: Correct of semaphore usage issues. From Gregory Nutt. + - USRSOCK: Fix re-definitions of struct iovec. From ligd. + - ICMP/ICMPv6 Connection: Change the type of id in + icmpv[6]_findconn to uint16_t From Xiang Xiao. + - ICMP/ICMPv6: Fix failure to poll ICMP socket issue. From + dongjianli. + + * Wireless/Wireless Drivers: + + - XBee: Fixes issue with timeouts. Timeouts were in ticks but + should have been in ms. This caused false triggers of timeout + causing redundant packets, etc. From Anthony Merlino. + - BCM43xx: Add missing logic to the BCM43xx IEEE 802.11 driver to + poll for more Tx data after the last transfer completes. From + Gregory Nutt. + - BCM43xx: Bring in some fixes from the 'Haywire' branch. From + Ramtin Amin. + + * Common Drivers: + + - Audio: Fix compile error in i2schar.c (CONFIG_DEBUG_ASSERTIONS=y) + From Masayuki Ishikawa. + - Audio I2S: Fix bad NULL pointer check From Juha Niskanen. + - Input: Fixed FT5x06 driver to correctly close (previously it + unregistered interrupt handler during close). From Marcin Wyrwas. + - MMC/SD: Fix an error that was causing SDIO multiple block + transfers from achieving full performance. From Bob Feretich. + - Sensors: Increases SPI frequency in MAX6675 from 400Khz to 4MHz. + From Alan Carvalho de Assis. + - Sensors: Remove comment references to touchscreens from ADXL345 + driver. From Russ Webber. + - Serial: Don't overwrite nwritten unconditionally on UART write + failure. From Xiang Xiao. + - Serial DMA: Move head/tail pointer reset to uart_recvchars_dma + since dma may be still transferring in the background. From Xiang + Xiao. + - Serial DMA: In DMA mode, the use of uart_disablexinit() is + insufficient to protect a critical section. + enter/leave_critical_section() must be used in those cases if + CONFIG_SERIAL_DMA=y From Xiang Xiao. + - Serial DMA: Fix typo error in uart_recvchars_dma() From Xiang Xiao. + - 16550 UART: u16550_txempty() should check UART_LSR_TEMT to avoid + some data left in the transmit FIFO From Xiang Xiao. + + * ARMv7-A: + + - ARMv7-A (and i.MX6): Add support for per-CPU IRQ and FIQ interrupt + stacks (bugfix). Add support so that up_assert will print the + correct interrupt stack on an assertion (FIQ stack is still not + printed). From Gregory Nutt. + + * ARMv7-R: + + - ARMv7-R: Fix some wrong configuration of program status + register. PSR_E_BIT bit should be set for big endian system. + PSR_A_BIT bis is set automatically as arm cortex-r4 reference + manual 3.7.4. So we don't need to set this bit. From EunBong Song. + - ARMv7-R: Fix some wrong MPU register definition. Change + MPU_RBAR_ADDR_MASK and MPU_RACR_TEX_SHIFT mask as arm cortex-r4 + reference manual. Region Base Address Register 0-4 bits are + reserved. MPU Region Access control register type 3-5 bits. From + EunBong Song. + + * ARMv7-M: + + - ARMv7-M, Cortex F7: Add a configuration to enable workaround for + r0p1 Errata 837070: Increasing priority using write to BASEPRI does + not take effect immediately. This update is required to be + serialized to the instruction stream meaning that after this update + completes, it takes effect immediately and no exceptions of lower + priority than the new boosted priority can pre-empt execution. + Because of this erratum, the priority boosting does not take place + immediately, allowing the instruction after the MSR to be + interrupted by an exception of lower priority than the new boosted + priority. This effect is only limited to the next instruction. + Subsequent instructions are guaranteed to see the new boosted + priority. This was raised in Bitbucket issue 113 from Vadzim + Dambrouski. From Gregory Nutt. + - ARMv7-M: MPU: mpu_log2regionceil needs take into account the + offset too From Xiang Xiao. + - ARMv7-M MPU: The prototype of mpu_log2regionfloor() changed; an + additional parameter was added. However, none of the calls to + mpu_log2regionfloor() were updated to pass the new, additional + parameter. From Gregory Nutt. + + * Infineon XMC4xxx Drivers: + + - XMC4 SPI: XMC4 SPI was working only for the first transfer From + Alan Carvalho de Assis. + + * Microchip/Atmel SAMv7 Drivers: + + - SAMv7 MCAN: Correct an error in the BUS_OFF reporting. In case of + BUS_OFF the old implementation was leading to a package storm. Now + it reports the error condition BUS_OFF only once. From Frank + Benkert. + + * NXP/Freescale LPC43xx Drivers: + + - LPC43xx CAN: Fix lpc43 CAN configuration. Configuration settings + were used and documented in README.txt files, but never in any + Kconfig file. From Gregory Nutt. + - LPC43xx: Make WWDT usable again. LPC43xx WWDT driver was not + updated when irq_dispatch grew an argument parameter. Also fixes + two typos and a naming inconsistency (WWDT vs. WWDG). From Jakob + Haufe. + + * NXP/Freescale Kinetis Drivers: + + - kinetis: USB0 fix interrupt storm on error. The ERROR bit of + USBx_ISTAT needed to be cleared once an error occurs. From David + Sidrane. + - Kinetis: SDHC fix SDIO driver so that DMA works. There were 2 + problems. The first was that the interrupt did test DINT and raise + a completion events. But since DINT is just an indication of DMA + completion, TC is a valid way to determine that the transfer is + complete. The second problem is that Software Reset For DAT Line + SDHC_SYSCTL[RSTD] clears the bits 24-0 in SDHC_PROTO this looses + the wide bus setting DTW From David Sidrane. + - Kinetis: (1) PIT add Liftime and Chaining, (2) flexcan fix + duplicate line and ordering, (3) kinetis_lowput.c LPUART data + format with parity fix. The 9-bit data mode is typically used with + parity to allow eight bits of data plus the parity, (4) lowputc + LPUART_BAUD_INIT has to be defined. Build fails with test case + enable LPUART0 and make UART1 console. If HAVE_LPUART_DEVICE is + defined then LPUART_BAUD_INIT has to be defined even if the LPUART + is not the console From David Sidrane. + - Kinetis: I2C ensure timeout on bus error. The code had a dead + wait on I2C_S_BUSY. Noise on the bus would cause the driver to + hang. Add timeout on invalid states of I2C_S_BUSY to allow the + upper layers do deal with restart or abort. From David Sidrane. + + * NXP i.MXRT Drivers: + + - i.MXRT Ethernet: I finally got the Ethernet CRC32 to work properly + after the FAE pointed me in the right direction: (1) Added CRC32 + functions for multicast address filtering, (2) Do not reset PHY + settings when doing an ifup, (2) Use chip's unique id as the device + MAC, and (4) Enable discard enet frames with errors at PHY layer. + From Jake Choy. + + * On Semi LC823450 Boards: + + - LC823450-XGEVK: Fix parallel build on lc823450-xgevk. This change + fixes an archive file (*.a) corruption by locking $(TOPDIR). + Please note that locking the current directory is insufficient + because some archive files such as libapps.a are specified with + absolute path. From Masayuki Ishikawa. + - LC823450-XGEVK: Change IOB related params for rndis. Since TCP + flow control scheme was changed, HTTP audio streaming has not been + working. These IOB params are not optimized but HTTP audio + streaming now works. From Masayuki Ishikawa. + + * STMicro STM32: + + - STM32 F7: Fix compile error caused by intentional use of fall + through From Daniel Agar. + + * STMicro STM32 Drivers: + + - STM32 F1-F4: Port Bob Feritich's change to STM32 F2 and F4 which + appear to have identical SD support and I/O compensation + requirements. + - STM32 F1-F4, STM32 F7, and STM32 L4: The STM32 RTC driver was + being selected by the global CONFIG_RTC option. That is in + correct. For example, if you want to disabled the STM32 RTC and + use an external RTC you cannot because the external RTC also + depends on the global CONFIG_RTC. The solution is to add a new + CONFIG_STM32xx_RTC configuration option the permits to you select + or deselect the STM32 RTC but still be able to selecte the external + RTC. From Gregory Nutt. + - STM32 F3 I2C: Fix compile error with I2C reset. From Juha + Niskanen. + - STM32 F7 Serial: Fix ioctl TIOCSSINGLEWIRE The TRM notes that UE + must be disabled in order to write HDSEL in USART_CR3. This was not + being done, so calls to TIOCSSINGLEWIRE were silently failing. + This change checks the state of UE in USART_CR1, clears the UE bit + before writing HDSEL, then re-enables it if neccesary. From Kurt + Kiefer. + - STM32 F7 DMA: DMA macros did not account for the increase from 8 + to 16 DMA channels. From Gregory Nutt. + - STM32 F7 I2C: I2C reset Configure I2C pins as GPIO output. Pins + were reset to inputs in the deinit(). This resets them to outputs. + From David Sidrane. + - STM32 F7: All of the SDMMC pins were set to 50 MHz, but not the + clock. This sets the clock to 50 MHz also. This combined with + turning on I/O compensation makes intermittent failures go away. + From Bob Feritich. + - STM32 F7: Port Bob Feritich's change to SDMMC2 and to all other + STM32 F7 architectures. Also add a configuration option to + automatically enable I/O compensation. From Gregory Nutt. + - STM32 F7 SDMMC: Fix data timeout errors with multi-block + transfers. From Bob Feretich. + - STM32 L4: Corrects some mistakes in pin definitions for the + STM32 L4 family. According to datasheet of STM32L496xx, STM32L475xx + and STM32L443XX the AF2 of PE14 is TIM1_BKIN2 not TIM2_BKIN. From + Daniel Pereira Carvalho. + - STM32 L4: Avoid using redundant CONFIG_STM32L4_STM32L4X2. This is + almost always same as CONFIG_STM32L4_STM32L4X3. Avoid duplication + to reduce macro clutter. This patch limits + CONFIG_STM32L4_STM32L4X2 usage to dependency tracking and pinmap. + Also enable ADC for CONFIG_STM32L4_STM32L4X5 (untested, but same + RM). From Juha Niskanen. + - STM32 H7 Serial: don't include stm32_dma.h From raiden00pl. + + * STMicro STM32 Boards: + + - STM32F4-Discovery: Fix pca9635pw LED driver compilation on + STM32F4-Discovery. From Alan Carvalho de Assis. + - STM32F4-Discovery: Krassimir Cheshmedzhiev claims that sys/types.h + needs to be included in the RGB LED file to avoid undeclared 'OK' + From Gregory Nutt. + - STM32F4-Discovery: Missing EXTERN(_vectors) in linker script. + From Gregory Nutt. + - Nucleo-L422KC: Fix RAM size; STM31L4x2xx has only 64Kb of RAM. + Remove references to I2C and SDIO: There is no I2C2 or SDIO on the + STM32F4x2xx. From Daniel P. Carvalho. + - Nucleo-L422KC: Fix stm32_userleds. After change LD2 to LD3 in + board.h stm32_userleds.c was broken. From Daniel P. Carvalho. + - Nucleo-L422KC: Fix TIMx clock configuration. Also removes + definitions related to timers not available in the STM32L432KC. + From Daniel Pereira Carvalho. + - Nucleo-L452RE: Fix TIMx clock configuration. This is cloned from + similar change to the Nucleo-L422KC. Also fixes DAC build + failure. From Juha Niskanen. + - B-L475E-IOT01A: Fix copy paste errors in names: + stm32_bringup->stm32l4_bringup. Noted by Freemans Goden. From + Gregory Nutt. + - STM32VL-Discovery: Changed the status LED to be the green one as + mentioned in the README file. Removed the global array for buttons + and replace it with the only button. Improve defconfig for the nsh + configuration. From Ouss4. + + * C Library/Header Files: + + - libc audio: Call nxsem_destroy in apb_free. From Xiang Xiao. + - libc netdb: The 'port' argument to the static alloc_ai() function + is always in network byte order. However, that static function was + still calling HTONS() on the port, incorrectly converting it back + to host byte order. From Gregory Nutt. + - libc netdb: Fix a link error in lib_gethostbynamer.c with protected + build. NOTE: g_lo_ipv4addr also exists in + net/loopback/lo_globals.c which can be linked with kernel build + only. From Masayuki Ishikawa. + - libc unistd : Fix backward conditional logic in Kconfig. From + Gregory Nutt. + - include/nuttx/compiler.h: Fix warning: __cplusplus is not defined. + Some gcc derived compiler do not define __cplusplus From Xiang + Xiao. + - include/nuttx/fs/binfs.h: Fix warning: Type defaults to 'int' in + declaration of 'mountpt_operations' From Xiang Xiao. + - include/nuttx/net/ethernet.h: Remove CONFIG_NET_ETHERNET guard + From Xiang Xiao. + - include/nuttx/semaphore.h: don't include nuttx/fs/fs.h. (1) Avoid + nested loops if CONFIG_SIG_EVTHREAD enabled, (2) semaphore.h + doesn't depends on fs.h. From Gregory Nutt. + - include/crc64.h: Fix warning: integer constant is too large for + its type From Xiang Xiao. + - include/limits.h and include/sys/types.h: Fix warning about + 'SIZE_MAX' redefined. include/nuttx/usb/audio.h: Fix warnings due + to '-' used whete '_' intended. From Xiang Xiao. + - include/spawn.h: Fix posix_spawnattr_destroy warning: 'the + address of attr will always evaluate as true' From Xiang Xiao. + - include/sys/types: Move wint_t and wctype_t from wchar.h to + types.h. This change is compatible as before since wchar.h + include types.h indirectly. This fixes a compilation error with + newlib's math.h: 'unknown type name wint_t' From Xiang Xiao. + - apps/include/netutils/netlib.h: Eliminate a warning about + AF_UNSPEC and AF_INET not defined. From Gregory Nutt. + + * Build System: + + - Build System: Fix parallel build in making context. This change + avoids running $(MKSYSCALL) and .context in parallel and ensures + that tools/mksyscall is built before it is actually used. From + Masayuki Ishikawa. + - Kconfig files: Fix several errors noted by Alex Denisov in + Bitbucket issue 115. From Gregory Nutt. + - apps Build System: Fix an error when building apps/ without + nuttx/, using only the NuttX export package and assuming that the + nuttx/ directory in not even present. In this case, the problem + fixed where the apps/Make.defs file was selecting tools from the + /tools directory which does not exist because TOPDIR=apps/import. + Instead, for this build case, I have not thought of any option but + to duplicate scripts as necessary in the apps/tools directory. + Also added a top-level target to compile the symbol table. Misc + fixes: quoting in scripts, some errors in script syntax. From + Gregory Nutt. + - apps/Application.mk: If a loadable module is generated the we + need to add logic to remove the loadable module in the 'make + clean' logic. From Gregory Nutt. + + * Tools: + + - nuttx/tools/Makefile.unix: Was not cleaning up export directory + if it was left from a failed export. From Gregory Nutt. + - apps/tools: Fix an error in mksymtab.sh From Masayuki Ishikawa. + + * NSH Library: apps/nshlib: + + - apps/nshlib: Fix 'while' and 'until' loop condition The loop + condition logic was inverted: 'while true; do echo "test"; done' + would exit immediately, while using 'until' would stay in the + loop. This is the opposite of how it is supposed to work. The + reason is that 'state' was set wrong because 'whilematch' is a + bool. From Beat Kng. + - apps/nshlib: I was able to cause an assertion with some typos in + testing the 'fi' command. Not an important thing, but this will + protect against the assertion. From Gregory Nutt. + - apps/nshlib: Increase the default configuration for the maximum + number of command line arguments to 7 (CONFIG_NSH_MAXARGUMENTS). + This is needed for 'mount' with the -o option. From Xiang Xiao. + - apps/nshlib: Do not dereference NULL 'pstate' in nsh_console.c. + From Juha Niskanen. + + * Examples/Tests: apps/examples: + + - apps/examples: Remove illegal calls into OS to initialize BINFMT + support. This must be moved to the board initialization logic + within the OS. From anchao. + - apps/examples/nettest: Fix typo: NET_LOOPBACK -> + CONFIG_NET_LOOPBACK nettest: Fix compilation error. Should enable + NET_SETSOCKOPT for preventing compilation error. From EunBong Song. + - apps/examples/ostest: Signal handling tests should use the same + configurable stack size as used in other tests, not + PTHREAD_STACK_DEFAULT. From Gregory Nutt. + - apps/examples/ostest: Attempt to make the nested signal test + compatible with the suspend/resume test. Some signals cannot be + caught when the suspend/resume configuration is in place. From + Gregory Nutt. + - apps/examples/smps: Fixes in some printf and in Kconfig. From + Mateusz Szafoni. + + * System Utilities: apps/system: + + - apps/system/cu: (1) Protect from possible re-definition of signal + values, (2) Fix CU ctrl-C hand when remote core hang. From ligd. + - apps/system/i2c: Fix a backward comparison in i2c_main.c. Noted + by Jakob Haufe. From Gregory Nutt. + - apps/system/nsh: Fix compile errors with + CONFIG_EXAMPLES_NSH_SYMTAB=y. From Masayuki Ishikawa. + - apps/system/ping and ping6: Send ID and seqno in network byte + order. From Xiang Xiao. + - apps/system/ping and ping6: Change dependency in ping and ping6 + Kconfig. These may be implemented in users sockets and, hence, + may need to be available even if ICMP and ICMPv6 sockets are not + support. From Xiang Xiao. + - apps/system/system: Add 'const' to make function prototype + compatible with OpenGroup.org requirement From Xiang Xiao. + - apps/system/zmodem: Fix error "sz_main.o: No such file or + directory" From Xiang Xiao. + + * Network Utilities: apps/netutils: + + - apps/netutils/ftpc: Fix handling of url-encoded strings From + Dmitriy Linikov. + - apps/netutils/ping: Remove unsupported ping. netutils/ping is not + supported anymore. It's better to remove this folder for + preventing confusing. ping is supported by system/ping. From + EunBong Song. + + * Wireless Utilities: apps/wireless: + + - apps/wireless/wapi: Remove dependency on CONFIG_EXPERIMENTAL from + Kconfig From Gregory Nutt. + + * GPS Utilities: apps/gpsutils: + + - apps/gpsutils/minmea: Include wchar.h in minmea.c file to fix + wint_t error From Alan Carvalho de Assis. + + * Interpreters: apps/interpreters: + + - Remove apps/interpreters/micropthon. There are several reasons + for this. (1) the current version 1.3.8 is very old and no one is + supporting it. (2) the port only includes the core micropython + logic and none of the Python libraries. As such it is useless in + any real application. (3) There have recently been compile + failures reported. It looks like this is due to changes in newlib + based toolchains that now bring in incompatible newlib header + files. See issue 104 at + https://bitbucket.org/nuttx/nuttx/issues/104/build-micropython-138-error. + With no one dedicated to the support of micropython, it can no + longer be carried in the NuttX apps/ repository. From Gregory Nutt. + +NuttX-7.27 Release Notes +------------------------ + +The 127th release of NuttX, Version 7.27, was made on November 14, 2018, +and is available for download from the Bitbucket.org website. Note +that release consists of two tarballs: nuttx-7.27.tar.gz and +apps-7.27.tar.gz. These are available from: + + https://bitbucket.org/nuttx/nuttx/downloads + https://bitbucket.org/nuttx/apps/downloads + +Both may be needed (see the top-level nuttx/README.txt file for build +information). + +Additional new features and extended functionality: + + * Core OS: + + - Assertions: Add 'BOARD_ASSERT_RESET_VALUE' in config/Kconfig and + replace reboot status '0' to 'CONFIG_BOARD_ASSERT_RESET_VALUE'. From + Gregory Nutt. + - Assertions: up_registerdump capture the general register if not yet + saved and up_saveusercontext is implemented, the register dump is very + useful to find the cause of failure. From Xiang Xiao. + - Assertions: up_stackdump() dump the full stack if stack overflow the + stack info is very useful to find the backtrace From Xiang Xiao. + - binfmt/ and libs/libc: Make exepath_*() more common: Move + exepath_*() related code to libc/misc, rename exepath_ to envpath_, + and rename BINFMT_EXEPATH to LIB_ENVPATH. From nchao. + - CLOCK: Support CLOCK_MONOTONIC in clock_getres.c. From Xiang Xiao. + - Clock Timekeeping: Use clock_basetime() to initialize + g_clock_wall_time to get the best initial RTC value and initialize + g_clock_last_counter too since the hardware may not start counting + from zero. From Xiang Xiao. + - exit(): Add SCHED_EXIT_KILL_CHILDREN option to kill all child threads + when the main thread of a task exits. From nchao. + - IOBs: Add an IOB notifier that will notify any registered threads + that want to known when an IOB has been freed. This is basically just + a wrapper around the generic notifier. Includes a divider that can be + used to reduce the rate of IOB notifications. From Gregory Nutt. + - Memory Manager: In mm_free(), add DEBUGASSERT()'s to catch memory + corruption early. From Petteri Aimonen. + - Memory Manager: Add debug option CONFG_MM_FILL_ALLOCATIONS to fill + all mallocs() with recognizable value. From Petteri Aimonen. + - sched/signal and syscall/: Add support for pselect() and ppoll() + functions From dongjianli. + - Task Groups: group_foreachchild() now iterates in reverse order since + the callback (e.g. group_killchildren) may remove the tcb from list. + From zhangyuan7. + - WDOG Timer: Improve accuracy of wd_gettime() in tickless mode From + ligd. + - Work Queues: Add a generic notification facility that runs on a work + queue. The notication facility can notify a group of subscribers to + an event via callbacks. This API is for use within the OS only. From + Gregory Nutt. + + * File Systems/Block and MTD Drivers + + - FAT: Add CONFIG_FAT_LFN_ALIAS_HASH to speed up creating long + filenames. Long filenames on FAT file systems have associated 8.3 + character alias short filenames. The traditional form of these is + FILENA~1.EXT with a running count of the number of similar names. + However creating this unique count can take several seconds if there + are many similarly named files in the directory. Enabling + FAT_LFN_ALIAS_HASH uses an alternative format of FI0123~1.TXT where + the four digits are a hash of the original filename. This method is + similar to what is used by Windows 2000 and later. From Petteri + Aimonen. + - FAT: Add CONFIG_FAT_LFN_ALIAS_TRAILCHARS alternative format for 8.3 + filenames. Traditional format for long filename 8.3 aliases takes + first 6 characters of long filename. If this option is set to N > 0, + NuttX will instead take first 6-N and last N characters to form the + short name. This is useful for filenames like "datafile12.txt" where + the first characters would always remain the same. From Petteri + Aimonen. + - FAT: if block driver wait seems to be a long one, give time for other + threads to run. From Petteri Aimonen. + - file_open(): Add file_open() implementation with some fully-function, + interim, placeholder logic. Change occurrences of open() followed by + file_detach() in the OS to file_open(). From Gregory Nutt. + - MX25LF25635F: Add support to Macronix MX25LF25635F serial NOR flash + From David Sidrane. + - nx_open(): Add nx_open() which is the same as open() except that it + does not create a cancellation point nor does it modify the errno + variable. Change most other, non-controversial calls to open() to + nx_open(). From Gregory Nutt. + - file_ioctl(): Replace calls to ioctl() in the OS to file_ioctl(). + From Gregory Nutt. + - mount: Add mount() support for file systems that require MTD drivers + (vs. block drivers). From Gregory Nutt. + - mount: Add support for mounting a file system with either a block or + an MTD driver. From Xiang Xiao. + - MTD FTL: Support BIOC_FLUSH ioctl From Xiang Xiao. + - MTD FTL: Make READAHEAD and WRITEBUFFER work independently of each + other. There have cases we use writebuffer but not readbuffer, so the + write buffer must be flushed before read. Let rwb driver do it. From + zhuyanlin. + - MTD FTL: Allocate eblock only when it's really needed From Xiang Xiao. + - MTD FTL: Add support support unlink operation to avoid the memory + leak. From Xiang Xiao. + - MTD Partition: Add register_mtdpartition() for MTD partition From + Xiang Xiao. + - MTD Partition: Remove the hard code partition name length From Xiang + Xiao. + - MTD Proxy: Make MTD device accessible via a character driver proxy + like block devices From Xiang Xiao. + - ProcFS: Change output of the ProcFS 'env' file so that it looks more + like output from the 'env' command. From Gregory Nutt. + - ProcFS: Add support to provide MLD statistics at /proc/net/mld. From + Gregory Nutt. + - ProcFS: Remove MTD ProcFS and mtd_procfsoperations() since we can now + get the same information from inode From Xiang Xiao. + - ProcFS: Add /proc/version support to get version info From iuhaitao. + - ProcFS: Add support for named MTD drivers in the pseudo file system. + This will, eventually, allow us to mount file systems that need MTD + drivers without having to fake an intervening block driver. + - R/W Buffer: Don't queue work to flush write buffer if + CONFIG_DRVR_WRDELAY == 0 From Xiang Xiao. + - R/W Buffer: Improve the rwb_read/write overlap performance From + zhuyanlin. + - SIM HOSTFS: Support S_IFSOCK, DT_LNK, O_DIRECT and O_SYNC From Xiang + Xiao. + - SPIFFS: Brings in a NuttX port of version 0.3.7 of Peter Anderson's + SPIFFS flash file system into NuttX. From Gregory Nutt. + + * Networking/Network Drivers: + + - Network Configuration Add new configuration CONFIG_NET_MCASTGROUP. + This option is selected automatically if either CONFIG_NET_IGMP or + CONFIG_NET_MLD are selected. Most conditional logic based on + CONFIG_NET_IGMP replaced with conditioning on CONFIG_NET_MCASTGROUP. + From Gregory Nutt. + - Network Device: Add notification logic for the case where the network + goes down. From Gregory Nutt. + - Network Device: Rename netdev_dev_lladdrsize() to netdev_lladdrsize() + and move the prototype to include/nuttx/nex/netdev.h, giving is global + scope within the OS. From Xiang Xiao. + - ARP: Redesign ARP table aging to simplify the net initialization + From Xiang Xiao. + - ARP: Check ifname match before sending packet. From Xiang Xiao. + - ARP and ICMPv6: Double the delay time on each iteration for ARP/ICMP + to fight work jitter better. From Xiang Xiao. + - ICMP/ICMPv6: Add NET_ICMP[v6]_NO_STACK for usrsock case From Xiang + Xiao. + - ICMPv6: Encapsulate the link scope address generation into + icmpv6_linkipaddr() From Xiang Xiao. + - ICMPv6: Remove the coupling between ICMPv6 and Ethernet by moving all + Ethernet stuff to neighbor_ethernet_out.c and make the mac address as + first field. From Xiang Xiao. + - ICMPv6 MLD: Implement Multicast Listener Discovery (MLD) protocol based + on RFC 2710 and RFC 3810. From Gregory Nutt. + - ICMPv6 MLD: Implement MLDv1 compatibility mode. From Gregory Nutt. + - ICMPv6 MLD: Implement 'Other Querier Present Timer'. This timer is + used to revert to Querier mode if there is no other querier on the + network. From Gregory Nutt. + - IGMP: Backport some MLD design improvements/fixes. From Gregory Nutt. + - IPv4 setsockopt(): Add implementation for all IPv4 socket options that + have implemented IOCTL command counterparts. From Gregory Nutt. + - IPv4/6 Socket Options: Add framework to support IPv4 and IPv6 + protocol socket options (i.e., SOL_IP and SOL_IP6). Handling of these + socket options was a necessary step on the way to ICMPv6 MLD support. + From Gregory Nutt. + - ICMPv6 Autoconfiguration: Don't take the network device down when + reconfiguring only the IP address from within ICMPv6 logic. + Recommended by Xiang Xiao in order to avoid the long delays of + bringing some networks back up. Normally it is required that the + network be in the "down" state when re-configuring the network + interface. This is thought not to be a necessary here because: (1) + The ICMPv6 logic here runs with the network locked so there can be no + outgoing packets with bad source IP addresses from any asynchronous + network activity using the device being reconfigured. And (2) incoming + packets depend only upon the MAC filtering. Network drivers do not + use the IP address; they filter incoming packets using only the MAC + address which is not being changed here. From Gregory Nutt. + - IPv6 Input: Add logic to skip over the variable number of IPv6 + extension headers that may be present between the IPv6 header and the + transport layer header. The extension headers are simply ignored. + This is necessary because with MLD, certain incoming messages may + have, at a minimum, a Router Alert Hop-by-hop extension header. + Additional changes to ICMPv6, TCP, and UDP input to handle the offset + protocol headers. From Gregory Nutt. + - IPv6 Neighbor: Simplify the neighbor table aging process From Xiang + Xiao. + - IPv6 Neighbor: Simplify neighbor_dumpentry() implementation From + Xiang Xiao. + - IPv6 Neighbor: neighbor_lookup() checks if the target IP belongs to + one of the local network devices. From Xiang Xiao. + - IPv6 Neighbor: Support neighbor_out() for multiple link layer at the + same time From Xiang Xiao. + - IPv6 setsockopt(): Implement the IPV6_JOIN_GROUP and IPV6_LEAVE_GROUP + socket options. From Gregory Nutt. + - TCP: Extend the TCP notification logic logic so that it will report + loss of connection events. From Gregory Nutt. + - SLIP: Add IPv6 support and fix minor issue From Xiang Xiao. + - TCP: Add TCP poll() logic to receive notifications when IOBs are + freed. From Gregory Nutt. + - TCP: In TCP backlog, add SOMAXCONN definition and implementation per + OpenGroup.org. From zhangyuan7. + - TCP/UDP: Extend send()/sendto() logic it also requires that at least + one IOB is also available to be able to send. From Gregory Nutt. + - TCP/UDP: Add notification logic when TCP or UDP read-ahead data is + buffered. From Gregory Nutt. + - TUN: Call ipv[4|6]_input dynamically by checking packet header and + remove the code duplication From Xiang Xiao. + + * Wireless/Wireless Drivers: + + - Broadcom IEEE 802.11: Add capability for Broadcom chips to get + firmware and CLM data from a mounted file system vs. in-memory data + structures. From Ramtin Amin. + - XBee IEEE 802.15.4: Add support for setting/getting tx power. From + Anthony Merlino. + + * Other Common Device Drivers: + + - GPIO: Support multiple registrations of GPIO signal events. From + Xiang Xiao. + - INA226: Add INA226 device driver. From Daniel P. Carvalho. + - MAX7219: Support all digits presented in the MAX7219 datasheet. From + Alan Carvalho de Assis. + - MLX90614: Add support for the Infrared Thermometer MLX90614 From + Alan Carvalho de Assis. + - RTC Driver: up_rtc_set_lowerhalf call clock_synchronize() for + external RTC. From Xiang Xiao. + - SYSLOG: Uncomment the g_syslog_channel->sc_flush call in + syslog_flush(). From Xiang Xiao. + - SYSLOG: syslog_initialize initialize dev/syslog too and call syslog + to add the prefix and timestamp. From Xiang Xiao. + - USB Composite and DFU drivers: Add support for Microsoft OS + descriptors. These Microsoft-only descriptors help in loading the + correct driver on Windows. They are especially helpful to give libusb + access to a custom device without having to manually configure/install + WinUSB driver. With this change DFU interface works automatically on + Windows 10 with dfu-util 0.9 and libusb 1.0.22. On Windows 7 it still + appears to need driver installation. From Petteri Aimonen. + - USB DFU Device: Add DFU Runtime driver for activating boot-loader + through USB command.

Add support for + composite configuration. From Petteri Aimonen. + + * Microchip PIC32MX Boards; + + - PCBLOGIC-PIC32MX: Remove support for the PCB Logic PIC32MX board. I do + not find any references to PCB Logic on the web and I do not believe + that this breakout board is available any longer. From Gregory Nutt. + + * NXP Freescale i.MX RT: + + - i.MXRT: Added support for the i.MXRT 106x family. From David Sidrane. + + * NXP Freescale i.MX RT Drivers: + + - i.MXRT: Add LPI2C driver.

From Mateusz Szafoni. + - STM32 L4: Add initial support for STM32L412 and STM32L422 chips From + Juha Niskanen. + + * STMicro STM32 Drivers: + + - STM32 ADC: Major refactor: Use STM32 ADC IP core version and ADC + available functions instead of chip family names in conditional + compilation. Replace family specific ADC headers with STM32 ADC IP + core version headers. Configurable sample time supported for all + chips, not just L1. Enable/disable interrupts supported for all + chips, not just L1. Add ADC resolution configuration.

From Ouss4. + + * RISC-V: + + - RISC-V GAP: This commit brings in support for the GAP8 architecture. + The GAP8 is a 1+8-core DSP-like RISC-V MCU. Also included is support + for the Gapuino GAP8 evaluation board. From hhuysqt. + + * Other Tools: + + - tools/tesbuild.sh: No longer installs and builds the NxWidgets + libraries. They are now a port of apps/. From Gregory Nutt. + + * Libraries/Header Files: + + - include/net and include/sys: Align the constant values with values in + the Linux kernel which makes targeting the usrsock server to Linux + kernel easier. From Xiang Xiao. + - include/netdb.h Add NO_ADDRESS definition From zhangyuan7. + - include/netinet/in.h: Adds definitions for IPPROTO_IPV6 socket + options to netinet/in.h. Adds missing fields to sockaddr_in6. Adds + struct ipv6-mreq. These changes all follow the opengroup standard for + netinet/in.h From Anthony Merlino. + - include/netinet/in.h: Add IPv4 SOL_IP socket options for symmetry + with IPv6 definitions added in a previous commit. Remove some + duplicate types from sys/sockio.h. From Gregory Nutt. + - include/netinet/in.h: Add other definitions required by + OpenGroup.org. From Gregory Nutt. + - include/netinet/in.h: Add Linux IP_PKTINFO and IPV6_PKTINFO + definitions. + - include/nuttx/net/ipv6ext.h: Create header file with all of the + definitions of IPv6 extension headers that I could find. From Gregory + Nutt. + - include/nuttx/net/mld.h: Add MLD header file based on RFC2710 and + RFC3810. From Gregory Nutt. + - include/sys/socket.h: With increased size of struct sockaddr_in6, the + size of struct sockaddr_storage in include/sys/socket.h must also be + increase so that it can contain the new, larger sockaddr_in6. From + Gregory Nutt. + + - libs/libc/misc: Add implementation of CRC8-CCITT. From Alan Carvalho + de Assis. + - libs/libc/modlib: Add per-module library symbol table support. From + nchao. + - libs/libc/net: Add basic implementation for recvmsg() and sendmsg() + per OpenGroup.org specification. From ligd. + - libs/libc/netdb: A few improvements to getaddrinfo: (1) Use the + protocol and socktype hints in returned address, (2) Ignore AI_PASSIVE + argument if hostname is not NULL From Anthony Merlino. + - libs/libc/netdb: Make DNS receive timeout configurable. From ligd. + - libs/libc/stdio: Eliminate recursive in conversion functions of + lib_vsprintf(). From Xiang Xiao. + - libs/libc/string: Add some new functions defined in POSIX.1-2017: + stpncpy(), strsignal(), psignal(), psiginfo(). From Gregory Nutt. + - libs/libc/string: Add memrchr() function From Xiang Xiao. + - libs/libc/string: Make strerror() return the string "Success" for + error = 0. From Petteri Aimonen. + + * Build System: + + - Makefile.unix/win: Remove deletion of Eclipse project files from make + distclean target. From Gregory Nutt. + - apps/Application.mk: Fix some build issues. (1) Unable to found + target 'context' when CONFIG_NSH_BUILTIN_APPS disabled. (2) Unable to + generate multiple programs. From Chao An. + - apps/Directory.mk: Fix distclean targets. Makefiles were not + removing generated Kconfig files. There was then no way to remove + this Kconfig files without manually deleting them one at a time. From + Gregory Nutt. + + * NSH: apps/nshlib: + + - apps/nshlib/, apps/examples/: Update to show newer file system + object types returned by stat(). From Gregory Nutt. + - apps/nshlib: Add support for the 'env' command. From Gregory + Nutt. + - apps/nshlib: Add support for NSH local variables if + CONFIG_NSH_VARS are set. These are like environment variables but + are local to NSH. The importance of this is that these variables + are *not* inherited when NSH creates a new task. The new command + 'export' was added. In this case, the NSH variable will be promoted + to an environment variable and will then be inherited by any tasks + executed by NSH. From Gregory Nutt. + - apps/nshlib: If CONFIG_NSH_VARS=y, the NSH 'set' command with no + argument will list all of the local NSH variables. From Gregory + Nutt. + + * Examples/Tests: apps/examples: + + - apps/examples/gpio: Align with GPIO driver update From wangyanjiong. + - apps/examples/ina226: Added INA226 example From Daniel P.

From Gregory Nutt. + - apps/examples/mlx90614: Add mlx90614 test example From Alan Carvalho + de Assis. + - apps/examples/mlx90614/: Include support to change device address on + mlx90614 From Alan Carvalho de Assis. + - apps/examples/fstest: Adapt the existing fstest example for SPIFFS: + For SPIFFS, add garbage collection and file system integrity IOCTL + calls. Call statfs() and show state of file system on each loop. Add + logic to dump logic content of SPIFFS. Ignore EINTR errors while + reading or writing. Add configuration option to customize stack + size. Detect when the media is full and stop writing files. Report + total file size. From Gregory Nutt. + - apps/examples/tcpblaster: Add an option to use poll() to pace input + or output. From Gregory Nutt. + - apps/examples/tcpblaster: Select CONFIG_LIBC_FLOATINGPOINT + automatically. Units in output are wrong: Not Kbps bus Kb/Sec. From + Gregory Nutt. + - apps/examples/udpblaster: Add option to use poll() on output (only). + From Gregory Nutt. + + * System Utilities: apps/system + + - apps/system/ping and apps/system/ping6: Set optind to zero in the + error case/. Move all ping preparation work into icmp_ping. Support + -W and -s option. Decouple the output from ping + logic. From Xiang Xiao. + - apps/system/ping and pings and apps/netutils/ping: Extract icmp ping + and icmpv6 ping6 logic from system/ to C-callable library in + netutils/. From ligd. + - apps/system/progmem: Remove this utility. It makes illegal direct + calls into the OS. From Gregory Nutt. + + * Network Utilities: apps/netutils: + + - apps/netutils/netlib and apps/examples/igmp: Adapt to use the + corrected, semi-standard version of struct ip_msfilter. From Gregory + Nutt. + - apps/netutils/chat and apps/examples/chat: 'constify' chat variables + and parameters From Xiang Xiao. + + * Wireless Utilities: apps/wireless: + + - apps/wireless/ieee802154/i8sak: Properly shuts down event thread. + From Anthony Merlino. + - apps/wireless/ieee802154/i8sak: Fixes i8sak name. Accidentally renamed + to i8ask in recent changes From Anthony Merlino. + - apps/wireless/ieee802154/i8sak: Adds support for getting/setting + transmit power. From Anthony Merlino. + + * Graphic Utilities: apps/graphics: + + - apps/graphics/NxWidgets: Move the NxWidgets repository into the apps/ + repository. Remove old apps/NxWidgets directory. Move NxWidgets + files into apps/graphics/NxWidgets. Integrate configuration/build + system. Fix file paths in file headers. Remove some duplicate + tools. Add new NxWidgets Unit Test configuration and build logic. + From Gregory Nutt. + - apps/graphics/NxWidgets: Add CNxString string + operator and + ::format() function. Add CNumericEdit option to include unit name + after the value. Make CNxWidget useWidgetStyle() public. From + Petteri Aimonen. + - apps/graphics/NxWidgets: Add CLabelGrid control for displaying text + in grid format. From Petteri Aimonen. + +Bugfixes. Only the most critical bugfixes are listed here (see the +ChangeLog for the complete list of bugfixes and for additional, more +detailed bugfix information): + + * Core OS: + + - Clock: Remove g_monotonic_basetime and g_clock_monotonic_time since + we don't need ensure monotonic time start from zero as state here: + http://pubs.opengroup.org/onlinepubs/009696899/functions/clock_getres.html + From Xiang Xiao. + - Clock: Don't call up_timer_gettime in clock_gettime() and + clock_systimer() to ensure the return value from them consistent with + clock_systimespec From Xiang Xiao. + - Clock Initialization: clock_inittime() needs to be done with + CONFIG_SCHED_TICKLESS and clock_initialize should skip + clock_inittime() for external RTC case since the RTC isn't ready yet. + From Xiang Xiao. + - IOBs: Work around some issues with the IOB throttle semaphore. It + has some odd behaviors that can cause assertions in sem_post(). Also, + it seems to get outside of its range occasionally. Need to REVISIT + this. From Gregory Nutt. + - IOBs: iob_navail() was returning the number of free IOB chain queue + entries, not the number of free IOBs. Completely misnamed. From + Gregory Nutt. + - PM: Use the start time of state btime to calculate thrcnt; remove the + loop whose count may be very big after the long idle From ligd. + - PM Uninitialization: Fix pm_domain_s.stime un-initialize caused time + error. From ligd. + - sched_kfree() and sched_ufree(): This patch prevent heap corruption + in a corner case where memory is freed while switching contexts. This + change forces all de-allocations via sched_kfree() and sched_ufree() + to be delayed. Eliminating the immediate de-allocation prevents the + problem with the the re-entrant semaphore because the deallocation + always occurs on the worker thread, never on the suspended task. From + EunBong Song. + - sigsuspend(): sigsuspend() shouldn't eat the pending signal but + dispatch all instead From Xiang Xiao. + - task_restart(): Was restarting tasks with all signals set in the + sigprocmask set. Should have restarted with the sigprocmask cleared. + Noted by Jeongchan Kim From Gregory Nutt. + - unsetenv(): Fix and error in unsetenv() when un-setting the last of + the environment variables. From Gregory Nutt. + - waitpid(): Remove a bad error check. From Gregory Nutt. + + * File System/Block and MTD Drivers: + + - FAT: Fix file data corruption in fat_truncate(). From Petteri Aimonen. + - Partitions: Try MTDIOC_GEOMETRY IOCTL before bops's geometry. + From Xiang Xiao. + - MTD Progmem: Change up_progmem_npages() to up_progmem_neraseblocks(). + page is a unit for read/write operation. eraseblock is a unit for + erase operation. up_progmem_npages() is a little bit confusing + because it returns number of erase blocks in flash memory. This patch + changes up_progmem_npages to up_progmem_neraseblocks. + up_progmem_eraseblock erase a block. so it's better to return the + erase block size than page size. From EunBong Song. + - R/W Buffer: Fix a lock issue From Xiang Xiao. + - SmartFS: Current sector should have a space for next entry size. If + not, we should move to next sector. From EunBong Song. + + * Networking/Network Drivers: + + - 6LoWPAN: Fixes bug in uncompress_addr handling of odd postfix. This + affected multicast compress/uncompress since it's the only logic that + used an odd postfix. The odd byte needs to be handled first, not + last. From Anthony Merlino. + - ARP and ICMPv6: Don't call d_txavail directly since it may point to + NULL From Xiang Xiao. + - ICMPv6: icmpv6_neighbor() shouldn't use the out of scope + variable(dripaddr) From Xiang Xiao. + - IPv6 input: Fixes logic in ipv6_input to handle more than ff02::/16 + multicast addresses. Don't forward mcast packets if scope is not + appropriate From Anthony Merlino. + - IPv6 Input: Fix a logic error when the received IPv6 srcaddr is a + multicast address. Exiting logic only supported UDP multicast. But + MLD and certain other ICMPv6 packets also require acceptance of + multicast packets. From Gregory Nutt. + - TCP: In TPC recv window calculations, in order to receive data we + must not only have IOBs available, but we must also have at least one + IOB chain qentry available. Otherwise, we will advertise that we an + buffer a lot of data when, in fact, we cannot. This is an + experimental fix to a performance problem noted by Masayuki Ishikawa. + From Gregory Nutt. + - TCP: Fix compiler error and warning when CONFIG_NET_SENDFILE=y From + Xiang Xiao. + - TCP Input: Fix recovery when ackseq > unackseq. The comment near + this line says "reset the number of outstanding, unacknowledged + bytes". However, the code actually resets the whole TCP connection. + It was changed to the current form in commit f034d84ea1f with no + explanation of the intent. Recover the line to what it was before that + commit. From Sakari Kapanen. + - TCP Write Buffering: Fix buffer release handling on failed buffer + allocation. Attempt to release write buffer on failed TCP write I/O + buffer alloc and tryalloc failed to wrb->wb_iob assertion. From Harri + Luhtala + - TCP/UDP: In the POLLOUT poll logic, request an immediate Tx poll from + the network device bound to the socket. From Gregory Nutt. + - UDP: On a failure to find the destination device, fallback to + netdev_default device if the device is not found, rather than + arbitrary using the device at the head of the list of devices. From + Xiang Xiao. + - USRSOCK: Revert previous commit to re-allow combination of usrsock + and NuttX TCP/IP stack. For example, in case device has Ethernet and + mobile connectivity and NuttX TCP/IP stack is used when configured to + use Ethernet connection and usrsock when configured to use modem + (modem TCP/IP stack through usrsock). From Jussi Kivilinna. + - USRSOCK accept(): Mark newconn ready before issue accept request to + avoid the case that the request is discarded due to the socket being + in the invalid state From Xiang Xiao. + + * Wireless/Wireless Drivers: + + - Broadcom 802.11 Driver: There were two functions that have a address + issue. In bcmf_read_sbreg() and bcmf_write_sbreg(): + SBSDIO_SB_OFT_ADDR_MASK should be used before map address space. + Noted by Shao Li in Bitbucket issue #126. From Gregory Nutt. + - Broadcom 802.11 Driver: Remove incorrect OR condition. Always true. + Noted by Shao Li in Issue 127. From Gregory Nutt. + - NRF24L01: Fix compilation errors. From Mateusz Szafoni. + + * Other Common Drivers: + + - ALARM Upper Half: Fix alarm ISR error when no CONFIG_SCHED_TICKLESS + drivers/timers/arch_alarm.c: Use uint64_t to avoid alarm 32-bit + overflow. From ligd. + - MAX11802: Fix compilation errors and allow setting PULL and SAMPLE + registers. From Petteri Aimonen. + - S25FL1: During a MTDIOC_GEOMETRY ioctl call, the driver was + incorrectly reporting the blocksize to be the same as the erasesize. + The blocksize should be 256 (the page size). This patch fixes that, + and now the SmartFS configration is working. From Ken Pettit. + - SYSLOG: nx_syslog's return value should include the timestamp length + From Xiang Xiao. + - SYSLOG: syslog_putc() calls sc_force in idle task even if interrupt + buffer enabled. The following cases may hang randomly in the bring up + phase: (1) boot up process and (2) suspend/resume process. Either + case runs in the idle task context, so it's difficult to debug the + hang issue if these output go through the interrupt buffer. From + Xiang Xiao. + - SYSLOG: Ensure interrupt log doesn't interlace in normal log. Don't + call syslog_putc in syslog_default_write because syslog_putc will try + to empty the interrupt buffer every time. From Xiang Xiao. + - UART 16550: Fix UART flow control issue. UART_MCR_RTS need be high + even UART_MCR_AFCE is enabled From zhangyuan7. + - USB RNDIS Device: Fix buffer overrun check in rndis.c. The rndis + driver has been working since 13 Nov 2017. However, I finally found + that it depends on network and buffer configurations. If a receiving + TCP packet is divided into smaller ones based on USB max packet size, + this condition check works correctly. From Masayuki Ishikawa. + + * ARMv7-A: + + - ARMv7-A: Replicate the same fix was previously committed for the + ARMv7-R. From Gregory Nutt. + + * ARMv7-R: + + - ARMv7-R: Fix error in cp15_flash_dcache. Change mcrne to mcr for + unconditional dcache. From EunBong Song. + + * ARMv7-M: + + - ARMv7-M Interrupts: Correct all ARMv7-M architectures. Interrupts + were not be disabled correctly on power up. Writing zero to the NVIC + SET-ENABLE registers has no effect. In order to disable interrupts, + it is necessary to write all ones to the NVIC CLEAR-ENABLE register. + Noted by David Sidrane. From Gregory Nutt. + + * Broadcom BCM2708 Drivers: + + - BCM2708 Serial: Juha Niskanen's fix related to STM32 + CONFIG_SERIAL_OFLOWCONTROL also applies to cloned logic in BCM2708. + From Gregory Nutt. + + * Intel x86: + + - Qemu i486: Correct .bss, IDLE stack, heap organization. From Gregory + Nutt. + + * NXP/Freescale LPC43xx Drivers: + + - LPC43 Ethernet: Fix Ethernet TX_EN pin definitions. TX_EN on LPC43xx + can be routed via P0.1 and PC.4 in both MII and RMII mode. Before, + P0.1 was hard-coded for MII and PC.4 was hard-coded for RMII. Also, + the definitions used inconsistent naming (TXEN vs. TX_EN). From Jakob + Haufe. + - LPC43 Serial: Fix copy-paste error: g_usart1port->g_uart1port. From + Dave Marples. + - LPC43 SDMMC: Fix the LPC43 family SDMMC card access: Clocks were + wrongly configured, way too fast because there is no primary divider + on LPC4330, the LPC43_SDMMC_DELAY register was not being set, the + LPC43_SDMMC_BLKSIZ and LPC43_SDMMC_BYTECNT registers had the wrong + values. From Dave Marples. + - LPC43 SDMMC: Corrected a problem in lpc43_dmasendsetup(). There was + no linked DMA descriptor code on the send side. The end result was + stalls while sending multiple sectors. This commit adds that in and + the send code is working much better. From Dave Marples. + - LPC43 SDMMC: With these changes the SDMMC card for LPC43 is now + working properly: Timing was dependent on CPU speed rather than + absolute time, end of transfer handling was a bit mixed up. It is + possible for data to still be in the FIFO (i.e. not have reached the + card) when a next write is requested, so we need to wait for that to + complete. Interrupt Status could be carried over from one transfer + episode to the next, corrupting progress. Multi-descriptor DMA + writing simply wasn't implemented. From Dave Marples. + + * NXP/Freescale LPC43xx Boards: + + - Bambino-200E: Correct calculation of SDMMC clock configuration. The + LPC43 has no SDMMC source clock divider. Error noted by Dave + Marples. From Gregory Nutt. + + * NXP/Freescale Kinetis: + + - Kinetis: Remove all attempts to reprioritize interrupts. From Gregory + Nutt. + + * NXP/Freescale Kinetis Drivers: + + - Kinetis I2C: I2C On failed reset re-initialization I2C and clocking. + If a reset fails, we still must reinitializes the I2C block so that + subsequent transfers will not cause a hard-fault due to the clock + being off. If that transfer fails it can try to reset again. From + David Sidrane. + - Kinetis Serial: Juha Niskanen's fix related to STM32 + CONFIG_SERIAL_OFLOWCONTROL also applies to cloned logic in Kinetis. + From Gregory Nutt. + + * NXP i.MXRT Drivers: + + - i.MXRT Ethernet: The board would not come up if I ran Nuttx from cold. + I dumped the PHY registers to see what the differences were and the + PHY was coming up in NANDTree mode. This is a mode for testing + connectivity between the PHY and the MAC. Switching this mode off in + the PHY registers has fixed the problem. From Dave Marples. + - i.MXRT Ethernet: Fix a race condition in setting up the Ethernet Tx + transfer. From Dave Marples. + - i.MXRT Ethernet: Corrections for the i.MXRT Ethernet: (1) Now the + Ethernet is completely re-initialized when an error occurs by means of + taking the interface down and back up but the PHY is _not_ + renegotiated for that case because that is very time consuming and an + error in the Ethernet is no reflection on the state of the PHY + anyway. (2) Explicitly sets the expected PHY address to zero (this + could be moved into the config rather than searching for it which + takes ages, and it's zero anyway for this board (that's the broadcast + address, and anything that cannot respond on that has multiple PHYs, + so that would be a new board). (3) Allows for the renegotiation of + the PHY to be optional when a reset is needed. If a non-renegotiated + reset doesn't result in good comms to the PHY then it'll automatically + be escalated to a renegotiated one. (4) Only performs a reset for + errors that need it (the CRITICAL_ERROR define). The list of errors + that need reset are somewhat arbitrarily chosen based on my prejudices + and might need to be revisited, but certainly the jabber errors don't + need reset, the partial packet is thrown away by the layer above + anyway. (5) Re-loads the multicast table on reset. (6) Adds a bit + more logging into the imxrt Ethernet module. From Dave Marples. + - i.MXRT LPI2C: Fixes 2 bugs in the for IMXRT1050: (1) I2C time out and + did not send STOP condition when sending single byte, (2) I2C could + not receive bytes after repeated start. From Ivan Ucherdzhiev. + - i.MXRT LPSRTC: SVNC LPCR register bits 0 & 1 are NOT reserved and + are, in fact, needed to enabled the SRTC. Now the SRTC is working. + From Ivan Ucherdzhiev. + - LPC54 SDMMC: Add support for and SDMMC errata. It appears that now I + can read the SD card successfully, but I get CRC errors when writing + to the card. From Gregory Nutt. + - LPC54 SDMMC: Ported Dave Marples fixes LPC43 SDMMC to the LPC54. + From Gregory Nutt. + - i.MXRT WDOG: Typos in bit definitions, wdog registers are 16 bits, + wdog update has to be within 255 clocks of unlock, define board + clocking based on divisor and muxes. From David Sidrane. + + * NXP i.MXRT: + + - i.MXRT: clockconfig bug fix: Fixed logic that was not clearing bits + as ~ was missing in &= mask operations. Use values from the board.h + file so set the Mux that selects the clock sources. Use board + defined PODF values to select clock. Only configure USDHC2 clocks + when board defines clocks. From David Sidrane. + + * NXP i.MXRT Boards: + + - IMXRT1050-EVK: Previous committed implemented SPI-based MMC/SD card + support conditioned on CONFIG_MMCSD. This interferes with the + implementation of MMC/SD card support using the SDIO-based + peripheral. This commit renames that atypical support to *mmcsd_spi* + and conditions using the SPI-based support on CONFIG_MMCSD_SPI which + will then not interfere with the MMC/SD support that can be + conditioned on CONFIG_MMCSD_SDIO. From Gregory Nutt. + + * On Semi LC823450 Boards: + + - LC823450: Fix up_allocate_heap() in lc823450_allocateheap2.c. For + lc823450, heap area in flat build mode must start just after + _eronly. Because bss/data area is allocated in lower address than + text area in SRAM. See ld.scripts for details. Also, this change + removes unused up_allocateheap.c From Masayuki Ishikawa. + + * Silicon Labs EFM32 Drivers: + + - EFM32 Serial: Juha Niskanen's fix related to STM32 + CONFIG_SERIAL_OFLOWCONTROL also applies to cloned logic in EFM32. + From Gregory Nutt. + - EFM32 USB Device: The epin_configure() function used the same eptype + as the TxFIFO number for all endpoints. This should probably be the + physical EP number, not the EP type. Suggested by Key Two. From + Gregory Nutt. + + * STMicro STM32 Drivers: + + - STM32* SPI: Don't rely on SPI_CR1_SPE to determine if peripheral has + been initialized. This change is needed specifically for the case + where a boot loader sets the SPE bit before starting NuttX. In that + case, the test in the SPI driver is wrong. This change fixes that by + assuring that NuttX has booted and initialized at least once (whether + or not SPE is set) before the driver starts refusing to initialize. + From Anthony Merlino. + - STM32 F0, F7, H7, L4 Serial: Fix use of CONFIG_SERIAL_IFLOWCONTROL + where CONFIG_SERIAL_OFLOWCONTROL was intended. From Juha Niskanen. + - STM32 TIM: Don't use hard-coded UIF interrupt in some functions. + From raiden00pl. + - STM32 (FS/HS), STM32F7, and STM32L4 OTGFS/HS Device: The + epin_configure() function used the same eptype as the TxFIFO number + for all endpoints. This should probably be the physical EP number, + not the EP type. Suggested by Key Two. From Gregory Nutt. + - STM32 F2: Fixes Kconfig options to include all STM32F20XX processors, + not just STM32F207. Also removes redundant STM32_STM32F429 depends + from Kconfig. STM32F4XXX already does this. From Anthony Merlino. + - STM32 F4 DAC: STM32F407VG has only one DAC. NDAC=2 causes + compilation error when trying to use e.g. STM32_DAC1_CR macro. From + Petteri Aimonen. + - STM32 F7 Serial: Force invalidation of data cache after DMA re-enable + when returning from low-power mode From Juha Niskanen. + + * STMicro STM32 Boards: + + - B-L475E-IOT01A: Correct timer source clock frequencies. From Freemans + Goden. + - Nucleo-L432KC: Fix SPI pin definitions in board.h. From Daniel P. + Carvalho. + + * MIPS32: + + - CP0 Definitions: Fix some copy-paste errors that cause malformed + comments and syntax errors when certain CP0 CONFIG1 bits are + referenced. Note in Issue 123 by Anonymous. From Gregory Nutt. + - microMIPS: Reported by Anonymous in Bitbucket Issue #129: When MIPS + port is built for microMIPS and then loaded as an application, the + __start entry point is entered in microMIPS mode, but the CPU core + initialization code there misses to set the config3ISAOnExc bit to 1. + Subsequently, exceptions are entered in MIPS32 mode, but the code base + was built for microMIPS. + + * Microchip PIC32MZ: + + - PIC32MZ Startup: In pic32mz-head.S, initialize the global pointer in + all shadow sets. From Ouss4. + + * Microchip PIC32MZ Drivers: + + - PIC32MZ Serial: Fix a typo in assignment of TTYS0 to UART6 From Ouss4. + + * Simulation: + + - SIM Network Driver: Fix error 'invalid operands to binary &' From + Xiang Xiao. + + * C Library/Header Files: + + - Fix typographical error in endian.h and resource.h From anchao. + - include/net/if.h: Adds extern "C" guard in include/net/if.h From + Anthony Merlino. + - include/netinet/in.h: Per OpenGroup.org, type of sin_port in struct + sockaddr_in must be in_port_t vs uint16_t. NOTE: in_port_t is + typdef'ed as uint16_t anyway. From Gregory Nutt. + - include/nuttx: Fix definitions used to access OS functions within the + libraries. In the FLAT build, we must always set the errno and/or + create cancellation points because the same library functions are used + within the OS as are used by applications. This could cause issues + for the OS but corrects some problems at the user interface. Noted by + Federico Braghiroli in Bitbucket issue 121. From Gregory Nutt. + - include/nuttx/clock.h: Fix uptime wrong if DEBUG_FEATURES and + SCHED_TICKLESS enabled. From Xiang Xiao. + - include/nuttx/fs/fs.h: Fix some backward parameters in a new macro + definition. From Gregory Nutt. + - include/nuttx/fs/fs.h: Register_mtddriver should depend on CONFIG_MTD + not CONFIG_MTD_PARTITION From Xiang Xiao. + - include/sys/socket.h: Renumber the socket types. They must begin at + 1, not zero. Socket type zero has a special meaning for some + interfaces. For example, getaddrinfo() uses a socket type of zero to + many any type of socket. The is no standard name for the + any-type-socket, but macOS uses SOCK_UNSPEC. NuttX will do the same. + Issue noted by Anthony Merlino. From Gregory Nutt. + + - libs/libc: Correct some errors in psignal() and stpncpy(). From + Lokesh B V. + - libs/libc/math: Add variable convergence in log() and logf() to avoid + hangs caused by failure to converge for very specific input values. + Also includes a small change to log() and logf() that improves + accuracy and convergence time. From Rajan Gill. + - libs/libc/stdio: Fix conversion for format specifiers in sscanf() that + appear right after a floating point format specifier. When + performing a floating point conversion the parsing code could consume + more than required characters from the input buffer. This made + impossible to convert input of form "1.1K" using format "%f%c". Fix + the issue by advancing the input buffer with the actual characters + converted as a float point number. From Mihai Serban. + - libs/libc/stdio: Remove CONFIG_NOPRINTF_FIELDWIDTH. That option + does, indeed, make the printf family of functions much smaller. But + it also adds a lot of complexity and makes the functions + non-standard. Removing this might break some of the tinier platforms + but it is the best thing to do for long term maintenance for for + OpenGroup.org compliance. + - libs/libc/stdio: Update to vsprintf(). This resolves the integer + field width problem if Issue 35 for the cases of integer, long and + long long integer types. The output now matches the output form + glibc. From Gregory Nutt. + - libs/libc/string: Correct the return pointer value from stpncpy() for + the case where the NUL terminator is transferred. From Gregory Nutt. + - libs/libc/string: Fix strrchr() so that it considers null terminator + as part of string. From Petteri Aimonen. + - libs/libc/wqueue: Eliminate a race condition noted by Xiang Xiao. + Use sigprocmask() so that we do not lose a signal. From Gregory Nutt. + - libs/libnx/nxfonts: Fix kerning of 'I' in Sans17x22 font. From + Petteri Aimonen. + - libs/libnx/nxfonts: In nxfonts_getfont(), avoid unnecessary warnings + for other whitespace chars also. From Petteri Aimonen. + - libs/libnx/mxmu: NXMU now re-validates window pointer for mouse + events. NXMU caches the previous window pointer so that further mouse + events can be sent to the same window. However, if the window is + destroyed while mouse button is held down, the pointer may become + invalid and cause a crash. This patch revalidates the pointer before + using it. From Petteri Aimonen. + - libs/libnx/nxtk: nxtk_bitmapwindow: Fix warning message when bitmap is + fully off-screen. From Petteri Aimonen. + + * Build System: + + - Fix issue with libcxx build. This was changed multiple times, but + should be fixed now. From Anthony Merlino. + - configs/Makefile and tools/Config.mk: Move single file copy to the + new function COPYFILE. This fixes the Windows native build case when + there is no cp or cp does not recognize Windows paths. From Anatol + Ivanov. + - tools/Config.mk and tools/Makefile.win: Force use 'cmd' for shell + with windows native build From Anatol Ivanov. + - tools/Directories.mk: Correct the path to the installed libcxx + directory. From Gregory Nutt. + - tools/Makefile.win/unix: Staging directory (and its libraries) should + be removed on 'make clean' (issue noted by Dave Marples). From + Gregory Nutt. + + - apps/Directory.mk: If the current directory contains a Kconfig file + and MENUDESC is not defined, then Directory.mk must not trash the + Kconfig in the current directory. From Gregory Nutt. + - apps/Makefile: Fix Windows native build patch extension. From Anatol + Ivanov. + + * Other Tools: + + - tools/Config.mk: Fix an error in RWILDCARD implementation From + Anthony Merlino. + - tools/configure.c: Add missing '\n' in printf statement + - tools/configure.c: Add missed -g option to getopt() string. From + Anatol Ivanov. + - tools/configure.c and tools/configure.sh: Fix Windows native + pre-build kconfig-conf incompatibility. From Anatol Ivanov. + - tools/csvparser.h: Extend MAX_PARMSIZE to 256. Fixes this issue: + 70: Parameter too long: ... From Xiang Xiao. + - tools/link.bat: Fix .fakelink creation. From Anatol Ivanov. + - tools/mkdeps.c: Fix '\0' missing with MinGW. From Anatol Ivanov. + + * NSH Library: apps/nshlib: + + - apps/nshlib: Correct maximum number of arguments that can be provided + to the mksmartfs command. From Eunbong Song. + - apps/nshlib: Add fflush to nsh_consolewrite(). This resolves this + problem: 'cat /dev/ttyCP &' followed by 'echo ls >/dev/ttyCP'. In + that case we can't get the 'ls' result immediately, because 'cat' cmd + uses nsh_consolewrite() and that uses fwrite with no fflush. We can + get the 'ls' result after type '\n', because nsh will fflush output + when get '\n'. From ligd. + - apps/nshlib: nsh_catfile() should not append '\n' if the last char in + file is already '\n' From Xiang Xiao. + - apps/nshlib: Fix warning g_oldpwd defined but not used + [-Wunused-const-variable] in nsh_envcmds.c. From Xiang Xiao. + + * Examples/Tests: apps/examples: + + - apps/examples/adc/Kconfig: CONFIG_BOARDCTL_ADCTEST does not exist + anymore and should removed as a dependency. From Eunbong Song. + - apps/examples/webserver/Kconfig: The webserver "app" allows for DHCP + client to be enabled. However, the Kconfig infrastructure does not + contain EXAMPLES_WEBSERVER_DHCPC config. Based on patch from + "Anonymous" attached to Bitbucket Issue #130. From Gregory Nutt. + + * System Utilities: apps/system: + + - apps/system/hexed: Fix memory leak From zhuyanlin. + - apps/system/i2c: Fix i2c_msg freq initialization problem. Typo + prevented I2C frequency initialization in a struct i2c_msg. From + dongjiuzhu. + - apps/system/system: Fix warning when passing argument 6 of + 'task_spawn' from incompatible pointer type + [-Wincompatible-pointer-types] From Xiang Xiao. + + * Network Utilities: apps/netutils: + + - Correct some network-related configuration variable names. All *_MTU + defines were changes to *_PKTSIZE gut that was not reflected in + apps/ From Gregory Nutt. + - apps/netutils/netlib/netlib_parsehttpurl.c: Correct handling of long + URLs as noted in Bitbucket issue #119 (in the nuttx/ repository, not + the apps/ repository). From Gregory Nutt. + - apps/netutils/codecs: "dst" overflow protection when base64 string + ends with "=" From Aleksandr Vyhovanec. + - apps/include/netutils/ipmsfilter.h: Eliminate error generated by bad + pre-processor logic. From Gregory Nutt. + + * GPS Utilities: apps/graphics: + + - apps/graphics/NxWidgets: Fix garbage returned when + CCycleButton::getValue() is called after removeAllOptions(). + CScrollingPanel should not draw outside the widget area. From + Petteri Aimonen. + +NuttX-7.28 Release Notes +------------------------ + +The 128th release of NuttX, Version 7.28, was made on January 19, 2019, +and is available for download from the Bitbucket.org website. Note +that release consists of two tarballs: nuttx-7.28.tar.gz and +apps-7.28.tar.gz. These are available from: + + https://bitbucket.org/nuttx/nuttx/downloads + https://bitbucket.org/nuttx/apps/downloads + +Both may be needed (see the top-level nuttx/README.txt file for build +information). + +Additional new features and extended functionality: + + * Core OS: + + - Critical Section Monitor: Adds data collection logic in support of + pre-task monitoring critical sections and pre-emption state. From Gregory + Nutt + - Critical Section Monitor: Add support for global pre-emption and + global critical sections to monitor as suggested by Xiang Xaio. From + Gregory Nutt + - Interrupt Time: Measurement of interrupt handler duration used to + be available only in Tickless mode since it used the high resolution + Tickless timer to measure interrupt time. This change adds + CONFIG_SCHED_IRQMONITOR_GETTIME which, if enabled, will force the + interrupt duration calculation to use the same high-resolution, + platform-specific timer as is used with the Critical Section Monitor. + This leads to two improvements: (1) You can now measure interrupt + duration in non-Tickless mode, and (2) in either mode, the interrupt + duration and the critical section measures will use the same + high-resolution timer and should, therefore, never be any discrepancy + due to different clock sources. From Gregory Nutt + - Context Switching Protection: Add debug assertions before each call + to up_block_task() to assure that there is no attempt to block an + IDLE task. From Dave Marples + - init Task: Allow the init task priority to be configurable. From + David Sidrane + - pthreads: Implement pthread_key_delete(). This involves some minor + changes to the group data structure. From Gregory Nutt + + * File Systems/Block and MTD Drivers + + - ProcFS: Extended the process ID ProcFS output to show per-thread + maximum time for pre-emption disabled and maximum time within a + critical section. From Gregory Nutt + - NXFFS: Pass unrecognized IOCTL commands to the contained MTD + driver. From Daniel P. Carvalho + - LittleFS: Adds an initial port the ARM mbed littlefs to NuttX. This does + not include FLASH formatting utilities. Depends on CONFIG_MTD_BYTE_WRITE. + From lihaichen + - AT25 MTD Driver: Added support for AT25DF081A serial flash chip. + From Marc Rosen + - MTD Configdata Device: Extends the MTD configdata device with the + following features / additions: + 1. Configurable option to use named config items instead of enumerated + ID/Instance numbers. + 2. Ability to iterate through the existing configdata items in the + /dev/config device. + 3. Ability to "unset" a configdata item. + 4. Ability to perform "flash_eraseall" on the /dev/config device. + From Ken Pettit + + * Networking/Network Drivers: + + - Telnet Driver: Add NAWS and poll interface to telnet for screen size + negotiation used with termcurses. From Ken Pettit + + * Wireless/Wireless Drivers: + + - BLE HIC Core: Add second RX work function From Lwazi Dube + - BLE IOCTL Commands: Add SIOCBTCONNECT and SIOCBTDISCONNECT ioctl + commands From Lwazi Dube + - CC2564: Add cc2564 HCI UART driver. From Lwazi Dube + + * Graphics/Display Drivers: + + - Sitronix ST7032i: Add support to Alphanumeric Sitronix ST7032i + display From Alan Carvalho de Assis + - NXP TDA19988: This commit brings in a complete, but untested, + implementation of a driver for the TI TDA19988 HDMI Encoder. This encoder + is used on the Beaglebone Black board. Since this driver is untested, it + requires CONFIG_EXPERIMENTAL in the configuration. From Gregory Nutt + + * Crypto: + + - crypto/aes.c: This change provides an improved AES cipher API in + addition to the existing routines. The reasons for this new API are: + 1) better performance, giving the possibility to avoid re-setting-up + the key for each AES block when the same key is used multiple times. + This is important for the current single user of AES, which is + related to storage and FTL. And 2) suitable for simultaneous use of + multiple AES keys, which will be required by the upcoming crypto + framework. It retains compatibility with the previous API, so there + is no need to change anything else right now. From Sebastien Lorquet + + * Other Common Device Drivers: + + - MMCSD SDIO: The mmcsd_sdio driver makes calls for dcache + invalidation through the chip specific architecture function + SDIO_DMARECVSETUP(). I changed the arch/arm/stm32f7 chips to use + arch_invalidate_dcache_by_addr() instead of arch_invalidate_dcache(). + + This commit includes additional changes to mmcsd_sdio.c. I + created SDIO_DMADELYDINVLDT() (DMA delayed invalidate) to + invalidate store-into mode dcaches after the DMA transfer. I + have been using SDIO_DMADELYDINVLDT() for several weeks now and + it has fixed the problems that I previously reported regarding + non-cache aligned buffer invalidation errors (for my store-through + dcache). However, it does not permit use of unaligned DMA buffers + for store-into mode dcaches. + + SDIO_DMADELYDINVLDT() is a NoOp unless the chip specific Kconfig + file selects CONFIG_ARCH_HAVE_SDIO_DELAYED_INVLDT. I have modified + all the stm32f7 chips to select it. From Bob Feretich + - SPI Lower Half Interface: Extend the HW features supported by SPI. + It now supports a deferred DMA trigger hardware configuration. From + Dave Marples + - DS28E17 1-Wire Driver: Optimize I2C write followed by read to same + address. From Juha Niskanen + - LMP92001: Add support for the TI LMP92001 Multi-channle DAC/ADC + device. From Abdelatif Guettouche. + - EEPROM Character Driver: Add support to Microchip AT24CM02 From + Alan Carvalho de Assis + - Microchip MCP73871: Add support to Microchip MPC73871 Battery Charger. + From Alan Carvalho de Assis + - MCP7941x: Add support for the Microchip MCP741x external RTC. From Ouss4 + - Sensirion SCD30: Driver for Sensirion SCD30 CO2 sensor. From Jussi + Kivilinna + - Sensirion SGP30: Driver for Sensirion SCD30 gas sensor. From Jussi + Kivilinna + - Sensirion SPS30: Driver for Sensirion SCD30 particulate matter sensor. + From Jussi Kivilinna + - USB CDC/ACM Device: When implemented usb cdc on nrf52840, I found + some issues with cdc driver: + 1. Lost data when receiving buffer is full; + 2. Low-water mask implement issue; + 3. Re-flush cdc buffer when enabling + 4. Serial dma is conflict with cdc , modify the serial.h + From Levin Li + + * MIPS32: + + - Configuration System: Allow Penguino for windows for the Windows + Ubuntu platform as well. + + * Maxim Integrated MAX326xx + + - MAX32660: Support for the MAX32660 was added (along with partial + support for other members of the MAX326xx family). The initial port + includes Clock configuration, timer, GPIO pin configuration, ICC, + and UART. Additional untested drivers are complete and ready for + testing: DMA, GPIO interrupts, SPI0 Master, TC, WDT. The following + drivers are not yet implemented: I2C and I2S. + + * Maxim Integrated MAX326xx boards + + - MAX32550-EVSYS: Basic support for the Maxim Integrated MAC3X660 + EVSYS is included. A basic NSH configuration is available and is + fully functional. Includes unverified support for an SPI0-based + SD card. + + * Microchip/Atmel SAMD21/L21 Drivers: + + - SAMD21/L21: Adds a complete ADC header file for SAMD21 and a partially + complete ADC header file for the SAML21. From Alexander Vasiliev + - SAMD21/L21: Export sam_i2c_master_initialize(int bus) to be used by + board config. From Alan Carvalho de Assis + + * Microchip PIC32MZ Drivers: + + - PIC32MZ I2C: Add support for the I2C bus. From Ouss4 + + * ARMv7-A + + - ARMv7-A MMU: Use TLBIMVA vs TLBIMVAAIS to invalidate the Cortex-A8 + cache. From Petro Karashchenko + + * ARMv7-M + + - Cortex-M7 Cache: This commit adds a new function + arch_invalidate_dcache_by_addr(). It takes the same parameters as + arch_invalidate_dcache(), but performs invalidation of only the lines + in cache that need to be invalidated. This new function could be + used as a a direct replacement for arch_invalidate_dcache(). From + Bob Feretich + - ARMv7-M: In the current implementation we only use very high + priority interrupts (levels 0, 0x10 and 0x20 in CORTEX-M speak) but + that means there are loads of lower priority ones that are + effectively unused. I have *not* changed the semantics of these + levels but have 'shifted' them to be based around the midpoint of the + available interrupts (0x80) rather than at the top end....that allows + for interrupts to be defined above (or, indeed, below) them as needed + by the application. This should have no functional effect on + existing code but adds in a clean capability to define higher + priority interrupts. From Dave Marples + + * Broadcom BCM2708: + + - BCM2708: Remove all support for the BCM2708/2835. This was added + only for support of the RaspberryPi Zero board which was previously + removed. The support was minimal and unverified. The removed files + can still be found in the Obsoleted directory. From Gregory Nutt + + * Broadcom BCM2708 Boards: + + - Raspberry Pi Zero: Remove the partial support for the Raspberry Pi + Zero. This port was started with the best of intentions but was + never completed. The board support can still be found in the + Obsoleted repository. From Gregory Nutt + + * Nordic NRF52 Boards: + + - Improve LED handling #if~#endif in nrf52_autoleds.c and + nrf52_userleds.c + Add Adafruit Feather nRF52 board LED support + Add Adafruit Feather nRF52 board + Add nrf52-generic + Replace 'pca10040' with 'generic' + Copy from nrf52-pca10040 to nrf52-generic + From Zou Hanya + + * NXP i.MX RT Drivers: + + - i.MXRT: Add PIT, GPT, and QIMER(TMR) header files From David Sidrane + - i.MXRT: Add FLEXPWM. From David Sidrane + - i.MXRT: Add ADC chip header From David Sidrane + - i.MXRT Build: Include up_systemreset and up_stackcheck.c From David Sidrane + - i.MXRT GPIO: Add GPIO Support Input daisy selection.

From Pavlina Koleva + + * On Semi LPC23450: + + - LPC23450: Add support for SPI flash boot. Also, remove unnecessary + code for the SPI flash boot. From Masayuki Ishikawa + + * On Semi LPC23450 Boards: + + - LC823450-XGEVK: Add linker script for SPI flash boot. From + Masayuki Ishikawa + - LC823450-XGEVK: Enable NFS client for RNDIS configuration. Also, some + stack size were adjusted to work with NFS From Masayuki Ishikawa + + * Simulation + + - Critical Section Monitor: Add low level timer support for simulation. From + Gregory Nutt + + * STMicro STM32: + + - Configuration: Simplify ARM core selection logic From Mateusz Szafoni + - Configuration: USB Host is an option. From David Sidrane + - STM32 L0: Brings in initial support for the STM23 L0. From Mateusz + Szafoni + + * STMicro STM32 Drivers: + + - STM32 ADC: Configurable ADC DMA mode (one shot mode, circular + mode). From Mateusz Szafoni + - STM32 ADC: Start conversion on startup is now possible if TIM + triggering selected. This can be useful to start ADC TIM conversion + for ADC IPv2 when opening ADC device. + - STM32 DAC: Unified naming for DAC interfaces From Mateusz Szafoni + - STM32 DMA: Add interfaces to interact with high priority DMA + interrupts. From Mateusz Szafoni + - STM32 DMA: Use STM32 DMA IP core version instead of chip family + names. From Mateusz Szafoni + - STM32 DMA: Add support for DMA v1 CSELR support. From Mateusz Szafoni + - STM32 HRTIM: Do not enable timers on startup if option from Kconfig + selected and add interface to enable/disable timers. From Mateusz + Szafoni + - STM32 PWM: Add timer enable/disable and frequency update to + low-level ops. From Mateusz Szafoni + - STM32 SPI: Implements the new deferred DMA trigger feature. From + Dave Marples + - STM32 F0 Build: Rename the stm32f0 directory to stm32f0l0 to make a + space for STM32 L0. Rename files, functions and defines, removing + the f0_ from the names in order to make them MCU agnostic. From + Gregory Nutt + - STM32 F0 GPIO: Add support for GPIO EXTI. From Mateusz Sfafoni + - STM32 F2 FLASH: stm32_flash_writeprotect() supported the same for + STM32F20XX as STM32F4XXX From Anthony Merlino + - STM34 F7 DMA: stm32f7 enable separate DMA per SPI configuration + From Daniel Agar + - STM32 F7 QEncoder: Ported the QEncoder from F4 to F7. From Eduard + Niesner + - STM32 F7 SPI: Port Dave Marples STM32 deferred trigger enhancement + to the STM32 F7 SPI drivers. From Gregory Nutt + - STM32 H7 SPI: Port Dave Marples STM32 deferred trigger enhancement + to the STM32 H7 SPI drivers. From Gregory Nutt + - STM32 L4 SPI: Port Dave Marples STM32 deferred trigger enhancement + to the STM32 L4 SPI drivers. From Gregory Nutt + + * STMicro STM32 Boards: + + - B-L072Z-LRWAN1: Add basic support for b-l072z-lrwan1. Nucleo boards + use as default ST LINK MCO as clock input from MCU and for this + HSEBYP must be enabled. From Mateusz Szafoni + - Nucleo-F103RB: Add board support. From Mateusz Szafoni + - Nucleo-F103RB: Add ADC and PWM examples. From Mateusz Szafoni + - Nucleo-F207ZG: Add board support. From Mateusz Szafoni + - Nucleo-F207ZG: Add ADC and PWM examples. From Mateusz Szafoni + - Nucleo-F302R8: Add high priority ADC interrupts example to the + 'highpri' configuration. From Mateusz Szafoni + - Nucleo-F334R8: Add support for ADC injected sequence to the 'highpri' + configuration, add triggering from TIM1. From Mateusz Szafoni + - Nucleo-F334R8: Add example for the SPWM generation (custom STM32 PWM + usage). From Mateusz Szafoni + - Nucleo-F767ZI: Use on board USB UART as default console. Board is powered + by USB which can be used as UART link for upload and console. Previously + it was set to use Arduino shield which developer may not have. From Phil + Coval + - Nucleo-F767ZI: Add ethernet config based on nsh configuration plus + stm32f769i-disco/nsh-ethernet. From Phil Coval + - Nucleo-L073RZ: Add basic support for nucleo-l073rz. Nucleo boards + use as default ST LINK MCO as clock input from MCU and for this + HSEBYP must be enabled. From Mateusz Szafoni + - Nucleo-L152RE: Add board support. From Mateusz Szafoni + - STM32F4 Discovery: Add timing support for the critical section + monitor using the DWT CYCNT register. From Gregory Nutt + - STM32F4 Discovery: If the Critical Section Monitor, modify the + ITM_LAR register to assure that the DWT cycle counter is enabled. + Suggested by Dave Marples. From Gregory Nutt + - STM32F4 Discovery: Add board support to display ST7032i From Alan + Carvalho de Assis + - STM32F4 Discovery: Add loadable application build support in + Make.defs From Masayuki Ishikawa + - STM32F4 Discovery: Update RNDIS configuration: (1) Add NFS and adjusted + stack size for usermain and telnetd client. (2) Add support for loadable + application and ping. From Masayuki Ishikawa + - STM32F4 Discovery: Update nsh configuration: (1) Add + CONFIG_BOARD_INITIALIZE=y, (2) Add CONFIG_EXAMPLES_HELLO=y. From Masayuki + Ishikawa + - STM32F429I-DISCO: Add high priority ADC interrupts example to the + 'highpri' configuration. From Mateusz Szafoni + - configs/nucleo-l073rz: Support for nrf24l01. From Mateusz Sfafoni + + * TI CCxx: + + - CC13x0 family and CC13x2/CC26x2: Basic, minimal support was added + for these two chip families. This is a Work-In-Progress: There is + just enough logic in place to support a simple NSH configuration. + However, the port is still missing certain, necessary hooks into the + TI ROM-based 'DriverLib'. As a result, the support is not fully code + complete and is totally untested. Support for the CC26x2, which is + nearly identical to the CC13x2 is fragmentary. Stay tuned. + Hopefully full support will be available in NuttX 7.29. + + * TI CCxx Boards: + + - LAUNCHL-CC1312R1: Board support is available for the TI + LAUNCHL-CC1312R1. That board support consists only of an unverified + NSH configuration. The primary purpose of this port for the time + being is simply support the core architecture bring-up. + + * TI AM335x: + + - AM335x: Adds initial support for the TI AM355x family. + - AM335x: Add minimal wdog logic needed to disable the watchdog timer. + Otherwise, the board is rebooted after certain time expires while NuttX is + running. From Petro Karashchenko + - AM335x: Switch to DMTimer2 for system tick generation. U-Boot does not + enable DMTimer1ms clocks hence it is not possible to use it until + implementation in am335x_clockconfig.c is ready. From Petro Karashchenko + + * TI AM335x Boards: + + - Beaglebone Black: Initial port for BeagleBone Black board support + (TI AM335x family based on Cortex-A8). Includes a basic functional NSH + configuration . From Petro Karashchenko + + * TI Tiva: + + - LM3S9B92: Add support for LM3S9B92. From Lwazi Dube + + * TI Tiva Drivers: + + - Tiva HCI UART: Port bluetooth HCI uart interface from stm32 to tiva + From Lwazi Dube + + * TI Tiva Boards: + + - TM4C1294-Launchpad: Add IRQBUTTONS support to tm4c1294 launchpad. + From Lwazi Dube + + * Tools: + + - tools/convert-comments.c: Add a tool to convert C++-style comments + to C89 C-style comments. From Gregory Nutt + - tools/detab.c: Add detab.c which will convert all tabs in a file to + spaces. From Gregory Nutt + - tools/lowhex.c: Add lowhex.c that will convert hexadecimal constants + in a file to use lower case representation. From Gregory Nutt + - tools/mkconfig.c: Add definitions to distinguish between tristate + 'y' and 'm' options. From Gregory Nutt + - tools/nxstyle.c: Add logic to detect long lines. From Gregory Nutt + - tools/nxstyle.c: Add -h for help. From Gregory Nutt + + * Libraries/Header Files: + + - include/nuttx/lcd/edid.h: Add EDID definitions From Gregory Nutt + - libs/libc/netdb: Make DNS retries configurable From Juha Niskanen + - libs/libc/netdb: Harden query logic against DNS spoofing. This + commit implements most of the RFC 5452 guidelines for making DNS more + resilient. We now verify response matches against what was queried + and use unpredictable query IDs. It is also checked that response + come from correct DNS server. Also fixes a buffer overflow when + querying hostnames longer than CONFIG_NETDB_DNSCLIENT_NAMESIZE. From + Juha Niskanen + - libs/libc/netdb: Support multiple IP addresses per hostname From + Juha Niskanen + + * NSH: apps/nshlib: + + - apps/nshlib: Add support to use SLCD as NSH Console From Alan Carvalho de + Assis + - apps/nshlib: Add support for CROMFS start-up script. From David Sidrane + - apps/nshlib: Add var expansion in NSH parse. From Daniel Agar + - apps/nshlib: Display built-in apps using multi-column mode like the NSH + commands. From Ken Pettit + - apps/nshlib: In all multi-column help output, calculate an optimal column + width rather than using a hard-coded width that may or may not be + appropriate. Also make the number of rows presented dependent upon the + maximum width of the widest column. From Gregory Nutt + - apps/nshlib: Adds addroute command options for setting default gateway. + Like 'addroute default '. From Anthony Merlino + + * Examples/Tests: apps/examples: + + - apps/examples/battery: Add Battery Charger Monitor Example From Alan + Carvalho de Assis + + * System Utilities: apps/system + + - apps/system/configdata: Adds an "cfgdata" command which allows + manipulation of the /dev/config items via the command line. One such use + for this utility would be to set a "macaddr" configdata item, etc. The + utility is sort-of like a u-boot env variable edit function: + + For instance, to set a "macaddr" when the new CONFIG_MTD_CONFIG_NAMED + option is selected, you would do: + + nsh> cfgdata set macaddr [0xfc 0x01 0x0b 0x45 0xa1 0x12] + (The brackets denotes an array of bytes) + nsh> cfgdata set hostname myboard + + or using the old ID,INSTANCE numeric method: + + nsh> cfgdata set 0,0 [0xfc 0x01 0x0b 0x45 0xa1 0x12] + (The brackets denotes an array of bytes) + nsh> cfgdata set 1,0 myboard + + You can also display all config items: + + nsh> cfgdata print all + Name Len Data + macaddr 6 0xFC 0x01 0x0B 0x45 0xA1 0x12 + hostname 8 myboard + + From Ken Pettit + - apps/system/critmon: Add a daemon to monitor critical section usage. From + Gregory Nutt + - apps/system/nsh: Set NSH priority if the NSH task was scheduled at a + different priority than the configured priority. From Gregory Nutt + - apps/system/nxplayer: Introduce CONFIG_NXPLAYER_MAINTHREAD_STACKSIZE. From + Masayuki Ishikawa + - apps/system/termcurses: Addition of termcurses libraries in + apps/system/termcurses From Ken Pettit + - apps/system/vi: New feature additions + 1. Vi startup feature to prepend the current working directory to the + supplied filename if it does not start with '/' absolute path + specifier. This allows editing files in the current directory + without needing to fully qualify the filename. + 2. Standard '~' empty screen line characters for proper identification + of empty '\n' only lines at the end of the file. + 3. Moving into insert or append mode now prints '--INSERT--' in the + status line and clears it upon exit. + 4. Integration with termcurses to detect special keystrokes and to + handle terminal type differences. Haven't yet converted all vt100 + print codes to termcurses equivalents. + 5. Support for up, down, left, right arrows, page-up, page-down keys in + command mode. + 6. Added 'b' command to move cursor 'b'ack to previous word. Honors the + command repeat value for multiple word moves. + 7. Added 'w' command to move cursor to next 'w'ord. Honors the command + repeat value for multiple word moves. + 8. Added 'f' and 't' commands to find characters on the current line. + Honors the command repeat value. + 9. Added the find 'n'ext command to repeat the previous find operation. + 10. Added the 'H', 'M', and 'L' commands to move the cursor to top, + middle and bottom of the display. + 11. Extended yank/paste to manage a paste buffer with character mode in + addition to line mode. Character mode allows cut / paste of + individual characters or groups of characters vs. full lines. + 12. Added support in the 'd'elete and 'y'ank commands for character mode + deletions such as 'dw', 'dfa', '2yw', etc. + 13. Added support in paste routine for multiple paste using command value + argument. + 14. Added support for the 'D' and 'C' delete and change to end of line + commands. + 15. Added support for 's'ubstitute key ('x' followed by insert mode). + 16. Modified yank / paste allocation scheme to avoid repeated alloc and + free of paste buffer. Uses a minimum allocation size scheme and only + does free / realloc when paste does not fit. If the paste is smaller + than the current allocation and the current allocation is larger than + the threshold, then the buffer is freed and a smaller buffer + allocated. Otherwise the existing buffer is used. + 17. Support for 'P'aste before current cursor position. + 18. Support for '?' reverse search mode. + 19. Support for 'J'oin next line with current line command. + 20. Printing of current row,col in status line of display. + 21. Command repeat '.' support for commands that modifiy text. + 22. Support in replace / insert mode for arrow keys, PGUP / PGDN, HOME, + and END. Using these will cause the command repeat buffer to reset + such that only the last text addition after a cursor movement is saved. + 23. Added 'X' delete previous command. + 24. Added "gg" go to top of document command sequence. + 25. Added "ZZ" save and quit command (equivalent to :wq). + 26. Implemented '^' goto first non-whitespace on current line, along with + '+' and '-' goto first non-whitespace on next / previous line. + 27. Added CR / LF goto first non-whitespace on next line in command + mode. From Ken Pettit ? + + * Network Utilities: apps/netutils: + + - apps/netutils/webserver: The webserver/httpd app is was broken when script + support was enabled (CONFIG_NETUTILS_HTTPD_SCRIPT_DISABLE). The root cause + has been tracked down to the "Content-length" not being available ahead of + time in this case (length of -1 passed to send_headers() ). On the other + hand, the server closing the socket does not result in FIN being sent to + the browser either (FIN not supported by NuttX yet). + + Simple solution: Add support for HTTP Chunked Encoding to webserver/httpd. + The change is simple. It adds a configuration option to enable chunked + encoding. When enabled, the implementation will auto-detect the cases where + content length is not available ahead of time, and will automatically + engage chunked encoding transfers. + + Without this patch, the browser/client hangs forever, as it is expecting + more data. With this patch, the browser displays the content. From Vlado + Vidovic + + * Wireless Utilities: apps/wireless: + + - apps/wireless/bluetooth/btsak: Add connect and disconnect commands to + btsak. From Lwazi Dube + + * Graphic Utilities: apps/graphics: + + - apps/graphics/pdcurs34: Integration of termcurses into pdcurses, plus + pdcurses updates for multi-thread support From Ken Pettit + - apps/graphics/pdcurs34: Adds a configuration option to pdcurses to enable + line-drawing character (ALTCHARSET) when using the short 16-bit chtype. + This is done by limiting the characters to 7-bit ASCII values and using the + 8-th bit as the A_ALTCHARSET bit. This allows a significant RAM savings 4K + - 20K depending on terminal size) while still allowing the nicer + line-graphic characters for border drawing. From Ken Pettit + + * Testing: apps/testing: + + - apps/testing/ostest: Add test for pthread-specific data. From Gregory + Nutt + +Bugfixes. Only the most critical bugfixes are listed here (see the +ChangeLog for the complete list of bugfixes and for additional, more +detailed bugfix information): + + * Core OS: + + - Assertions: Identify the running task correctly when dumping task + state information. It takes time to switch to the target task after + g_readytorun has been modified. If panic/assert happen during this + period, the dump will contain the incorrect and confusing information + due to the difference between the real running task and the return + value of this_task(). This change resolve this problem by adding + g_running_task to track the real running task through the context + switch. From Xiang Xiao + - Assertions: Correct duplicated logic from commit + dbf01d12b7321d1b48b68d3b69842a853b049376. Checking for PID == zero + is not a valid way to test for the IDLE task in all configurations! + This is only true in the single CPU configuration. In multiple CPU + configurations, there will be a separate IDLE task for each CPU with + a different PID and an alternative check must be used. NOTE: The + logic fixed in some places still lacks sufficient intelligence in SMP + mode to find the right stack for the CPU IDLE thread and could still + show the wrong stack. From Gregory Nutt + - Interrupt Prioritization: Remove all driver-specific logic that may + set the interrupt priority to anything but the default. There is no + good reason to change the interrupt priority unless you just want to + debug a difficult problem. OR if you want to use high priority + interrupts. In that case the specific interrupt priorities will need + to be set by board-specific logic. From Gregory Nutt + - Memory Management: Revert "This patch prevent heap corruption as in + below case." This solution to the problem noted by EunBong Song + results in major memory fragmentation and out-of-memory + conditions on the PX4 platform. On that platform the lower priority + work queue is very low priority and essentially never runs when the + system is busy. As a result, the systems gets slowly starved of + memory until failures and bad behaviors begin to occur. From Gregory Nutt + - Memory Management: This is a replacement for EunBong Song's reverted + change. This change adds (1) logic in getpid() to return an error instead + of the PID if the (apparent) currently executing task is not marked as + RUNNING. Then (2) mm_trysemaphore() (the root implementation of both + kmm_trysemaphore() and umm_trysemaphore()) will know that the (apparent) + running task cannot be the holder of the semaphore. How could the + non-running task be trying to get the MM semaphore? I think only in the + exact scenario that Eunbong Song has described. So this new solution + should provide the same protection as the original change but without the + bad consequences to memory usage. From Gregory Nutt (with corrections + from David Sidrane) + - Memory Management: In implementation of calloc(), verify that the number of + elements times the size of an element will not overflow type size_t. This + is required by the SEI CERT C coding style and resolves anonymous Bitbucket + Issue #139 From Gregory Nutt + - sigtimedwait(): Remove unnecessary disable of pre-emption. From + Gregory Nutt + - _exit(): Update all architecture-specific _exit() implementations + so that they correctly call the scheduler instrumentation layer for + the new task that runs when the old one exits. This missing + instrumentation was confusing the Critical Section Monitor logic with + uses this instrumentation to track the state of critical sections. + From Gregory Nutt + - sched_foreach(): sched_foreach() should not have to hold the + critical section over the entire traversal. It should be acceptable + to simply only the critical section while one entry is being + processed (the caller can always call sched_foreach within a critical + section is greater stability is needed). From Gregory Nutt + - task_spawn(): Correct description of input parameters to + task_spawn_exec(). Noted by: JeongchanKim From Gregory Nutt + + * Crypto: + + - crtypo/: This change: + + Avoids the use of up_aesinitialize() entirely, which resolves + dependency problems, because this function does not make sure that + an actual hardware aes implementation was made available: each SoC + is now responsible to ensure the AES hardware is initialized before + first use. This applies to lpc43xx, stm32 and sam34. + + Remove definitions of the NEVER used aes_init and aes_update + operations. The new AES API will be more suitable. + + From Sebastien Lorquet + + * File System/Block and MTD Drivers: + + - opendir(): Corrects a problem with opendir() noted by Petteri + Aimonen in Bitbucket Issue 132: "opendir() fails for FAT filesystem + with trailing slash in path". I see the following behaviour on NuttX + 7.26, where I have SD card mounted on /flash and a directory called + "frm" on it: + + opendir("/flash") returns (DIR *) 0x1000c580 + opendir("/flash/") returns (DIR *) 0x1000c5d0 + opendir("/flash/frm") returns (DIR *) 0x1000c620 + opendir("/flash/frm/") returns (DIR *) 0x0 + + From POSIX specs for opendir(): "A pathname ... that ends with one or + more trailing slashes shall be resolved as if a single dot character + ( '.' ) were appended to the pathname." So for mount points, + opendir() works correctly, but for FAT32 filesystem it fails to open + directory if the path has a trailing slash... + + NOTE: You would not see this problem if you call opendir() indirectly + in NSH (like 'ls -R /') because NSH contains logic to remove trailing + '/' characters from paths. From Gregory Nutt + - dup()/dup2(): dup() and dup2() were broken some time back. + fs_dupfd() was return returning OK on success, not the file + descriptor of the duplicated fd. From David Sidrane + - ProcFS: Remove the unnecessary critical section From Xiang Xiao + - CROMFS: Fix hardfault. From David Sidrane + - SmartFS MTD Driver: Fix smart_write_alloc_sector sector size mapping. + Was not correctly calculating the encoded sector size for small (256) + byte or large (>= 4096 byte) sectors. Noted by Daniel P. Carvalho. + Fix from Ken Pettit + - AT25 MTD Driver: Fixed missing opening parenthesis. From Marc Rosen + - MTD Configdata MTD Driver: Check return value mtdconfig_readbytes(). + From Jussi Kivilinna + - S25FL1 MTD Driver: Minor change for the s25fl1 QSPI FLASH driver which + fixes additional sectorshift vs. pageshift confusion. From Ken Pettit + + * Networking/Network Drivers: + + - All network drivers! Change pre-processor logic that selects the + high priority work queue or gives preferential treatment to the high + priority work. All network logic must run on the low priority work + queue! Or suffer the consequences. From Gregory Nutt + - Socket Clone/Dup: On a failure to start the TCP monitor, the cloned + socket is closed but is not properly freed, leaving it attached to a + TCP connection structure with the wrong reference count. From + Gregory Nutt + - ARP: Fix whitespace after ARPHRD_IEEE80211 in ARP header file. From + Daniel Agar + - 6LoWPAN: Fixes decompression of ipaddr from MAC address. The logic + used to populate the IP from the radio address should match + sixlowpan_ipfromsaddr/sixlowpan_ipfromeaddr From Anthony Merlino + - 6LoWPAN: Fixes logic surrounding the Universal/Local bit. This bit + represents whether the IID is locally/globally administered. The U/L + bit is bit 1 of the MSB of the EUI-64. It should only be inverted in + cases where there is a full EUI-64. In cases where the IID is derived + from say, a short address, this bit should be forced to 0, indicating + that it is locally administered. See: + https://tools.ietf.org/html/rfc4291#section-2.5.1 + https://tools.ietf.org/html/rfc4944#section-6 + https://tools.ietf.org/html/rfc2464#section-4 + From Anthony Merlino + - 6LoWPAN: IEEE802.15.4 stores and uses addresses in little endian + order. From Anthony Merlino + - 6LoWPAN: Address comment regarding avoiding double lookup of address + context. From Anthony Merlino + - 6LoWPAN: Record and restore d_buf on entry/exit of sixlowpan_input. + This avoids an issue where d_buf gets set to NULL by 6LoWPAN, and + then is used by forwarding logic from another network interface + before getting set back to the drivers internal buffer. From Anthony + Merlino + - 6LoWPAN: sixlowpan_input should always return 0 if the incoming frame was + consumed. From Anthony Merlino + - TUN Driver: Fixes a problem reported by Masayuki Ishikwawa: Recently I + noticed that ARP response packet is corrupted when I tried to run + bluekitchen with the latest tun.c in TAP mode. If I revert commit + 8193c28e9126c9cb89042e80d6ebab7485a831e4, then it works again. From Xiang + Xiao + - Telnet Driver: Add missing logic to set read event flags in poll() + method. From Ken Pettit + + * Wireless/Wireless Drivers: + + - BLE: Fix uninitialized variables. From Lwazi Dube + - BLE GATT header file: Fix struct name. From Lwazi Dube + - BLE GATT: Remove unnecessary GATT ioctls From Lwazi Dube + + * Graphics/Display Drivers: + + - ST7032: Fix seek method. Was not taking into account the offset for the + SEEK_END case. Did not account for negative offsets. On errors, it was + clobbering the filep->f_pos setting. From Gregory Nutt + - PCF8574 Backpack: Fix seek method. Had the same problems as noted for + ST7032 driver. From Gregory Nutt + + * Common Drivers: + + - Button Upper Half: Fix two bad NULL checks From Juha Niskanen + - PWM Interface: Remove dependency on CONFIG_PWM for the upper-half + PWM header. This allows compilation for the lower-level PWM drivers + even if the upper-half PWM logic is not used. From Mateusz Szafoni + - Various I2C Drivers: In most I2C drivers, correct upper index value + in I2C trace dump. Eliminates the extra NONE event from the trace + dump output.

If my understanding is correct then these interrupt + manipulations aren't doing anything anyway because prioritization + stops secondary interrupts arriving and, even if they did work, they + would have introduced race conditions for the period of time between + the interrupt arriving and further interrupts being disabled. From + Dave Marples + - MPU/Protected Mode Build: Revert "arch/arm/armv7-m: MPU: + mpu_log2regionceil needs take into account the offset too". Masayuki + Ishikawa reports that this commit breaks ALL PROTECTED mode builds. It + violates the basic requirements of the use of the MPU in protected mode. + Those basic requirements are: + 1. The MPU region must be aligned to the base address of the memory + region being mapped (it may NEVER extend before the memory region). + That is, the following MUST always be zero: (base & ((1 << l2size) - 1)) + 2. The MPU region must never extend beyond the end of the memory region. + That is, the following must be true: size >= (1 << l2size) + From Gregory Nutt + + * Microchip PIC32MX Drivers: + + - PIC32MX Ethernet: Fix a comparison in a debug assertion.

Insertion of line above 1st line using 'O' caused line to be + inserted on 2nd line. Fixed. + 3. Paste buffer from 'dd' was being free'd after the 'p'aste operation, + preventing multiple paste opportunity. Fixed. + 4. The cursor was not being bound to the line end and was allowed to + 'hover' over the '\n' EOL character. This caused wierd (relative to + standard vi) insertion locations and cursor movement with 'a'ppend + and 'i'nsert. Fixed. + 5. The 'vi_shrinkpos' position didn't take the end of file pointer into + account when calculating 'curpos', 'prevpos' variables causing + wierdness when deleting things near the end of the file. Fixed. + 6. The 'yy'ank command was improperly deleting the text from the + document instead of simply yanking to the paste buffer. Fixed. + 7. The 'dd'elete line funciton was not copying the deleted line to the + paste buffer as part of the delete operation. Fixed. + 8. The bottom line of the screen was sometimes being used for document + text and other times for command / find entry. Fixed by reserving + the bottom the bottom line for status / command only. + 9. When scrolling up / down through a file, the cursor position was not + preserved and moved further and further to the left column based on + the line lengths of the lines visited. Fixed. + 10. The display was being COMPLETELY redrawn with each keystroke, + causing the responsiveness to be unbearable. Fixed. Added logic to + dynamicall indicated which portions of the screen need to be updated + (full display, current line to end of screen, current line only, + none). + 11. The individual display line updates were being performed a character + at a time by calling the vi_putch() function, causing slow + performance, especially in telnet or USBCDC sessions where there is + a lot of overhead per packet. Fixed by calling vi_write() instead + with a block of characters with breaks as needed for TAB exansion. + 12. The forward delete 'x' operation allowed deletion through '\n' + characters causing lines to be joined. This is different from + standard vi where 'x' at the end of a line performs a delete + backward operation. Fixed. + 13. When in 'ex' or find sub-modes (':' or '/' bottom line modes), + hitting backspace with empty text did not return the operation to + command mode like it does in standard vi. Fixed. + 14. Performing a 'find' opertation would only search from the current + cursor position to the end of the file and did not wrap like in + standard vi. Fixed. + 15. Loading a file that was larger than the initial text allocation + would force a call to 'vi_extendtext', marking the file as modified + when in fact it hadn't even been loaded yet. Fixed. + 16. Combined vi_insert_mode and vi_replace_mode into a single function + to save code space since they are nearly identical routines. + 17. In command mode, backspace was deleting characters which is + different from standard vi. Backspace in command mode normally + simply moves the cursor left / to the previous line. Fixed. + 18. Added code to handle boundry conditions when the file is new and + commands are applied to an empty file. + 19. Fixed vi_shrinktext so it doesn't allocate a zero-length buffer when + the last character in the file is deleted. + 20. The 'x' command was not copying to the paste buffer. Fixed. + 21. Fixed parsecolon routine to properly deal with ":wq" command sequence. + From Ken Pettit + + * Wireless Utilities: apps/wireless: + + - apps/wireless/bluetooth/btsak: 'bt bnep0 info' outputs a reversed addr. It + should print BDAddr: aa:bb:cc:dd:ee:ff instead of BDAddr: + ff:ee:dd:cc:bb:aa. From Lwazi + - apps/wireless/bluetooth/btsak: Fix some errors in btsak. From Lwazi Dube + - apps/wireless/bluetooth/btsak/btsak_main.c: Fix address parsing. From + Lwazi Dube + - apps/wireless/bluetooth/btsak: Remove unnecessary gatt get commands. From + Lwazi Dube + - apps/wireless/bluetooth/btsak/btsak_scan.c: Fix reversed address. From + Lwazi Dube + - apps/wireless/ieee802154/i8sak: Fixes issues related to re-running + daemon. Releases lock when releasing daemon. Re-sets daemon_shutdown so + that a subsequent daemon launch does not immediately return. From Anthony + Merlino + +NuttX-7.29 Release Notes +------------------------ + +The 129th release of NuttX, Version 7.29, was made on March 25, 2019, +and is available for download from the Bitbucket.org website. Note +that release consists of two tarballs: nuttx-7.29.tar.gz and +apps-7.29.tar.gz. These are available from: + + https://bitbucket.org/nuttx/nuttx/downloads + https://bitbucket.org/nuttx/apps/downloads + +Both may be needed (see the top-level nuttx/README.txt file for build +information). + +Additional new features and extended functionality: + + * Core OS: + + - Configuration: CONFIG_NFILE_DESCRIPTORS=0 can no longer be used to + disable the file system. NuttX with no file system does not make + sense and is no longer supported. From Gregory Nutt. + - Rename most internal OS functions from sched_* to nxsched_* to + indicate that they are NuttX internal functions (some renaming is + still needed). From Gregory Nutt. + - Rename all internal OS functions from task_* to nxtask_* to indicate + that they are NuttX internal functions. From Gregory Nutt. + - Rename sched_process_timer to nxsched_process_timer. Rename + sched_timer_expiration to nxsched_timer_expiration. Rename + sched_alarm_expiration to nxsched_alarm_expiration. Those are the + appropriate names for an internal sched/ function (still many named + incorrectly). From Gregory Nutt. + - Standardize naming: Rename os_start() to nx_start(), rename os_smp* + to nx_smp*, rename os_bringup to nx_bringup, rename all internal + static functions to begin with nx_ vs os_. From Gregory Nutt. + - Initialization: Remove the option CONFIG_BOARD_INITTHREAD. Now, if + CONFIG_BOARD_INITIALIZE is selected, then the board_initialize() + logic will ALWAYS run on an internal kernel thread. This will + prevent the problems people have had doing inappropriate + board_initialization on the IDLE thread. From Gregory Nutt. + - Initialization: Add support for CONFIG_BOARD_EARLY_INITIALIZE. If + this option is selected then nx_start() will call a board-provided + function board_early_initialize() immediately after calling + up_initialize(). Rename board_initialize() to + board_late_initialize(). From Gregory Nutt. + - Signal Delivery: Add a flag to the TCB to indicate that we are in a + signal handler. Use this flag to assure that a there is never + attempts to nest signal handling operations on a thread. This was + guaranteed before but when locking of pre-emption during signal + delivering was eliminated in a previous commit, there was a remote + possibility of an attempt to do nested signal handling. This flag + assures that there is only one signal handled at a time. From + Gregory Nutt. + - Signal Handler Security: The architecture-specific signal handler + return register state is saved and available on the user stack. + This commit reorders some logic so that certain, critical registers + are preserved in the TCB. This eliminates most malicious exploits + which more the return address, for example, but does not make the + logic 100% secure. From Gregory Nutt. + - Timer Interrupt Procssing: Add a configurable call out to a + user-provided function, 'timer hook', on each timer interrupt. From + Gregory Nutt. + - PM Activity: Add pm_staycount() API for get stay numbers. This + function is currently not used and a waste of FLASH space. From ligd. + - Pthreads: Add support for pthread_mutex_timedlock From Leif Jakob. + - Pthread Spinlocks: Add a very preliminary implementation of the new + POSIX pthread_spinlock_* interfaces. From Gregory Nutt. + - Critical Section Monitor: Remove SCHED_IRQMONITOR_GETTIME to + simplify the clock source selection: (1) Use up_critmon_gettime if + SCHED_IRQMONITOR, (2) Call clock_systimespec if SCHED_TICKLESS, (3) + Don't collect timing info for all other cases. From Xiang Xiao. + - Work Queue Notification: Notifier can now work with either lpwork + or hpwork. From Xiang Xiao. + - Protected Build: Add add a new field (us_heapend) to struct + userspace_s that labels the end of the heap. From Xiang Xiao. + + * Binary Loader/Kernal Modules/Shared Libraries + + - Shared Libraries: Implement dlerror() using strerror(). From Xiang + Xiao. + - Shared Libraries: Add LD_LIBRARY_PATH environment variable + support. From anchao. + - ELF Loaders: Optimize elf load speed: (1) Don't zero out memory, + (2) Reduce the initial buffer size to 32 bytes. From Xiang Xiao. + - ARM ELF Relocation: Add support for the R_ARM_THM_JUMP11 relocation + type. This relocation type may be generated when LTO optimization + is enabled. From anchao. + - ELF Modules: Add relocation buffer table to reduce filesystem + access. From anchao. + - ELF Modules: Add symbol buffer table to reduce filesystem access. + From anchao. + + * File Systems/Block and MTD Drivers + + - Filesystem Mount: Move the union inode_ops_u i_mtd field into the + mount section of inode_ops_u and remove the guard to simplify fs + which support both block and mtd. From Xiang Xiao. + - ROMFS: Add support to mount a ROMFS volume using an MTD driver + interface using the standard mount() operation. From Xiang Xiao. + - LittleFS: VFS wrapper improvement: (1) Support block device + interface, (2) support ioctl, stat and sync file operation, (3) + support forceformat and autoformat option, (4) update file->f_pos + and dir->fd_position, (5) remove the internal struct from dir, and + (6) remove mtd byte read/write requirement. From Xiang Xiao. + - UnionFS: Support mount of UnionFS from the NSH command line. From + Xiang Xiao. + + * Networking/Network Drivers: + + - UsrSock: Add mutual exclusion so that only user can perform a + socket request From zhangyuan7. + - UDP: Initialize callback address structure to avoid random values + in padding. From anchao. + + * Wireless/Wireless Drivers: + + - SX127x: Initial support for SX127x LoRA radio From Mateusz Szafoni. + + * Graphics/Display Drivers: + + - Graphics: Fix a naming collision: Ye olde nx_start that started + the NX graphics is now nxmu_start(). nxmu_start() is now + prototyped in nxmu.h (instead of nx.h). From Gregory Nutt. + - NX Server Startup: Extend nxmu_start() so that receives a display + number as an argument. This makes it possible to have multiple + instances of the NX server running on boards that support multiple + displays. Also includes updates to boardctl() to accept display + number paramters. From Gregory Nutt. + - Graphics: nx_openwindow() and nxtk_openwindow() now accept an + additional 'flag' parameter. This argument is current used only to + select a RAM backed, per-window framebuffer. From Gregory Nutt. + - Per-Window Framebuffers: Windows may now be optionally created + with a RAM frambuffer backing up the window content. Rending into + the window will result in rending into the backup framebuffer, then + updating the physical display from the framebuffer. The advantage + of this option is that the application that manages window will no + longer receive redraw() callbacks. Those calls normally occur when + a window "above" moves exposing a portion of the window below. If + this option is selected, then the system will redraw the exposed + portion of the window from the backup framebuffer without + intervention of the window applications. This greatly reduces the + complexity of the application and performance of the window at the + expense of increased memory usage. Redraw requests in other cases + are also suppressed: Changes to window position, size, etc. As a + consequence, some manual updates will be required when certain + events occurr (like removing a toolbar from a window). NOTE: A + significant amount of RAM, usually external SDRAM, may be required + to use per-window framebuffers. + + * Other Common Device Drivers: + + - Driver Notifications: Support signal notification through + SIGEV_THREAD in all drivers that provide signal notifications: + RTC, Joysticsks, buttons, Zero-Crossing, wireless, FT80x, Timer, + PHY. From Xiang Xiao. + - Watchdog Driver: Support auto-monitor service From Gregory Nutt. + - Timer and Alarm Drivers: Implement up_critmon_gettime and + up_critmon_convert and remove the critical section from + current_usec to infinite recursion. From Xiang Xiao. + - RTC Driver: Protect the RTC state with a semaphore. From Xiang + Xiao. + - Serial Upper Half: Call pm_activity() when characters are received + on a console device. From Gregory Nutt. + - MPU60x0: Initial support for TDK InvenSense MPU6000 and MPU6050 + 6-axis gyroscope and accelerometers. This commit supports SPI + media only. From Bill Gatliff. + - EEPROM Driver: Add configurable SPI eeprom frequency. From + Valmantas Paliksa. + - GPIO Driver: Support reading and writing gpio pins using cat and + echo. From Valmantas Paliksa. + - MCP2515: Add MCP2515 clock input config to KConfig. From + Valmantas Paliksa. + - MAX7456: Support for the Maxim MAX7456 on-screen-display chip. + From Bill Gatliff. + + * Common Board Logic: + + - boardctl(): up_testset() can now be accessed by applications via + the boardctl() interface rather than attempting to call it + directly. pthread Spinlocks are not available unless the + architecture supports the up_testset() operation. From Gregory + Nutt. + - boardctl(): Add support for BOARDIOC_NXTERM which can be used to + create an NxTerm terminal. From Gregory Nutt. + - boardctl(): Add boardctl() commands to replace direct calls to + nxterm_redraw() and nxterm_kbdin(). From Gregory Nutt. + + * Microchip PIC32MZ Drivers: + + - PIC32MZ Timers: Add support for the PIC32MZ timers (driver, + lowerhalf, freerun and oneshot) From Abdelatif Guettouche. + + * Common ARM Options: + + - arch/arm: Move FPU options to a common place and unify the usage + by removing ARCH_CORTEXRxF. From Xiang Xiao. + - arch/: Unify the cache interface for all architectures that + support a data cache. From Xiang Xiao. + - ARMv7-M/A/R: Add a architecture-specific new barriers.h header + file that provides the memory barrier definitions that were + previously in the (now unified) cache.h header files. From Gregory + Nutt. + + * ARMv7-A + + - ARMv7-A: Support thumb mode and fix interworking issue. From + zhangyuan7. + - ARMv7-A: Add weak attribute to arm_data_initialize so platform + could provide the new implementation as needed. From zhangyuan7. + - ARMv7-A: Add SCR bit definitions. From Xiang Xiao. + - ARMv7-A: Add mmu_l1_map_regions() to remove the code duplication. + From Xiang Xiao. + - ARMv7-A: Add the initial cortex-a7 architecture support From + zhangyuan7. + + * ARMv7-M + + - ARMv7-M: stackcheck allow faulting stack calculation to make it to + the up_assert reg dump From David Sidrane. + + * Microchip/Atmel SAMD21/L21 Drivers: + + - SAMD2/L2: Add RS485 support to SAMD2L2 serial.

From Mateusz Szafoni. + - OmnibusF4: Initial support for the OmnibusF4 family of flight + management units. "OmnibusF4" is not a product name per se, but + rather a design spec that many product vendors adhere to. The spec + defines the major components, and how those components are wired + into the microcontroller. Airbot is one such vendor, and they + publish a schematic here: http://bit.ly/obf4pro. Other software + that supports the OmnibusF4 family include Betaflight, iNAV, and + many others. PX4 recently added support as well, using their own, + non-upstreamed, bespoke port of NuttX. No code from those resources + is included in this port. From Bill Gatliff. + - OmnibusF4: Add MAX7546 support. From Bill Gatliff. + + * TI CCxx: + + - CC1312R1: Code complete and builds successfully. Stalled on + further radio development. I planned to integrate the IEEE 802.15.4 + radio interface, but the Cortex-M0 interface is not available with + an open license. + + * TI CCxx Boards: + + - LaunchXL-CC1312R1: Add support for on-board LEDs and buttons. The + LauchXL-CC1312R1 NSH Configuration is now fully functional. From + Gregory Nutt. + - LaunchXL-CC1310: Clone LED and button support from the + LaunchXL-CC1312R1. The number of LEDs and buttons as well as DIO + usage is identical (Still not functional). From Gregory Nutt. + + * Tools: + + - tools/rmcr.c: Add a tool to remove carriage returns and dangline + whitespace at the end of lines. From Gregory Nutt. + - tools/nxstyle.c: Can now detect if the C comment closing is not on + a separate line. From Gregory Nutt. + - tools/nxstyle.c: Make sure that all files begin with a comment on + line 1 (which should be the file header). From Gregory Nutt. + - tools/nxstyle.c: Add check for multiple definitions of local + variables on a line. From Gregory Nutt. + - tools/nxstyle.c: Beef up logic that detects multiple variable + definitions per line. From Gregory Nutt. + - tools/nxstyle.c: Add capability to detect CamelCase identifiers. + From Gregory Nutt. + - tools/nxstyle.c: Add logic to detect a blank line following a left + brace or a blank line preceding a right brace. From Gregory Nutt. + - tools/nxstyle.c: Don't complain about certain lowercase characters + in otherwise uppercase pre-processor identifers: IPv6, IPv4, + ICMPv6, IGMPv2, p as a decimal point, d signifying a divisor. It + was a bad idea to let the door open a crack for there. While they + improve readability, the inconsistently also causes other + problems. From Gregory Nutt. + + * Build System: + + - Makefiles: Modify tools/Makefiles to add a "Do not Edit" warning + on defconfig files From Alan Carvalho de Assis. + + * Libraries/Header Files: + + - lib_vsprintf() (Nano): Add newlib-nano lib_vsfprintf has been + added and is now the default support for the printf family. This + fprintf code was originally adapted from AVR libc and provides + improved floating point output support, including 'g' mode and + making 'f' mode include digits past the decimal by default. The + newlib version can be found here: + https://salsa.debian.org/electronics-team/toolchains/newlib-nano. + That project is GPL overall, but the newlib-nano printf portions + are BSD licensed as described in the COPYING.NEWLIB file. From + Keith Packard. + - lib_vsprintf() (Nano): Added support for long lont types. From + Johannes. + - lib_vsprintf() (Nano): Added hh type modifier (without extending + the flag variable).

From Johannes. + - lib_vsprintf() (Nano): Cleaned naming and allow for leading zeros + in argument number (which doesn't make sense but should be). From Johannes. + - lib_vsprintf() (Legacy): Add support for %g format which, for + these purpose, is equivalent to %f except that trailing zeroes are + suppressed. From Gregory Nutt. + - vscanf(): Moved vscanf logic to lib_sscanf.c Switched to stream + interface (tricky, because the old implementation used massive read + ahead, which isn't suitable for streams, chars already read are + gone). Added hh, h, and ll modifiers. From Johannes. + - scanf() and fscanf(): Added scanf and fscanf based on enhanced + vscanf(). From Johannes. + - uname(): Add build date and time to uname output (like Linux). + From Gregory Nutt. + - strsep(): Add strsep BSD/Linux function. From Xiang Xiao. + - netdb: Hostname support no longer depends on CONFIG_NET since the + host name is also useful in the non-network environment. + CONFIG_NET_HOSTNAME changed to CONFIG_LIB_HOSTNAME.

From Xiang Xiao. + - include/fixedmath.h: Add macros for conversion between types + b16_t and type double From Gregory Nutt. + - include/limits.h: Define NL_ARGMAX (as well as some of the other + 'invariant values' per + http://pubs.opengroup.org/onlinepubs/7908799/xsh/limits.h.html). + From Johannes. + - linclude/limits.h: Add 'range 9 999999' to CONFIG_LIBC_NL_ARGMAX + to Kconfig. Per OpenGroup.org, the minimum value for NL_ARGMAX is + 9. From Gregory Nutt. + - include/nuttx/lcd/edid.h: Add extended EDID block IDs From + Gregory Nutt. + + * apps/ General: + + - apps/: Follow up the kernel signal-related change in various files + under examples/ and graphics/. From Xiang Xiao. + - apps/: Update for corrected name of standard header file. Should + be dlfcn.h, not dllfcn.h. From Gregory Nutt. + - apps/: The file system can no longer be disabled. Remove all + conditional logic based on CONFIG_NFILE_DESCRIPTORS==0 From + Gregory Nutt. + - apps/: Remove/replace all conditional logic based on + CONFIG_NSOCKET_DESCRIPTORS == 0. That value is always greater than + zero now. In places just replace with #ifdef CONFIG_NET. From + Gregory Nutt. + - apps/: Some updates due to NuttX renaming: + CONFIG_BOARD_INITIALIZE is now CONFIG_BOARD_LATE_INITIALIZE; + board_initialize() is now board_late_initialize(). From Gregory + Nutt. + - apps/: Graphics interfaces nx_openwindow() and nxtk_openwindow() + now accept an additional 'flag' parameter. From Gregory Nutt. + + * NSH: apps/nshlib: + + - apps/nshlib/nsh_netinit.c: Update for changes to signal + notification structures. From Gregory Nutt. + + * Examples/Tests: apps/examples: + + - apps/examples/ini_dumper: New example program. ini_dumper is + example program that dumps content of ini file in pretty ascii table. + It is using inih ini library in fsutils/inih. From Michal Lyszczek. + - apps/examples/modbusmaster: Add Simple Modbus master example. + This example only supports Read/Write HoldingRegisters, but it is + easy to extend it to support Read/Write Input/Coils/etc. + Originally creatd by Vytautas in 2016 and updated with minor fixes + for this commit. From Alan Carvalho de Assis. + - apps/examples/pwfb: Added a test/example at apps/examples/pwfb + that was used for initial testing of the per-window framebuffer + feature.

From + Xiang Xiao. + + * Testing: apps/testing: + + - apps/testing/: Move all file system tests from examples/ to + testing/ (cxxtest, fstest, nxffs, smart, smart_test, smp). From + Gregory Nutt. + - apps/testing/cxxtest: Add a README file. From Gregory Nutt. + - apps/testing/ostest: Add test of pthread_mutex_timedlock() From + Gregory Nutt. + - apps/testing/ostest: Fix several errors in the setvbuf() test. + From Gregory Nutt. + - apps/testing/scanftest: Port of Greg King's scanf test + (https://github.com/cc65). From Johannes. + + * Tools: apps/tools: + + - apps/tools/check-hash.sh: Add a tool check hash on downloaded + packages. From Michal Lyszczek. + +Bugfixes. Only the most critical bugfixes are listed here (see the +ChangeLog for the complete list of bugfixes and for additional, more +detailed bugfix information): + + * Core OS: + + - Signals: Restructure nxsig_deliver() so that the signal handler is + not called with the pre-emption disabled (or, at least no with + pre-emption disabled by nxsig_deliver() itself). From Gregory Nutt. + - Critical Section Monitor: Move up_critmon_* to arch.h avoid the + duplicated declaration. From Xiang Xiao. + - Assertions: Architecture-specific assertion logic should dump CPU0 + IDLE stack only when PID equals 0. IDLE threads of other CPUs do + not need this special check. From Xiang Xiao. + - Message Queues: Change 'int prio' to 'unsigned int prio'. + According to open group specification, priority field in mq_* + functions should have unsigned type: + http://pubs.opengroup.org/onlinepubs/9699919799/basedefs/mqueue.h.html. + From Michal Lyszczek. + - Timer Expiration: Fix macro SEC2TICK() 32-bits overflow by using + uint64_t in calculation. From ligd. + - Kernel Memory Manager: In mm/kmm_heap/kmm_kernel.c, remove unused, + duplicated kmm_heapmember(). From Xiang Xiao. + - User Memory Manager: Ensure all user allocation try sbrk before + fail From Xiang Xiao. + - waitid(): Could exit without leaving critical section on some + error conditions. From Gregory Nutt. + - IOBs: iob_allocwait() should decrease semcount manually. From + Xiang Xiao. + - IOBs: iob_copyin() should wait for each buffer and adjust the + return value of iob_copyin_internal return to simplify the code + From Xiang Xiao. + - IOB Notifier: Don't check iob_navail in iob_notifier_setup to + avoid a potential race condition. From Xiang Xiao. + - IOB Debug Dump: Format the whole line before log to avoid the + multiple timestamp prefix in each line. From Xiang Xiao. + - SHM: Convert bytes to pages by MM_NPAGES instead of MM_PGALIGNUP + From Xiang Xiao. + - SHM: shmget() should hould call shm_extend() to allocate the + physical memory. From Xiang Xiao. + - Page Allocator: mm/pgalloc: shouldn't just allocate one page + always. From Xiang Xiao. + - Granule Allocator: Fix the wrong data in g_1bit_info and make the + internal function static. From Xiang Xiao. + - srbk(): Fix a backward conditional test. Should call + mm_initialize() when brkaddr equal zero From Xiang Xiao. + - sbrk(): Pass ARCH_HEAP_VEND as maxbreak argument From Xiang Xiao. + - ELF Headers: Move elf related arch function to include/nuttx/elf.h + because the implementation is located in libs/libc/machine and in + order to avoid the conflict with the 3rd party libraries and clean + up the file inclusion: (1) Remove redundant elf32.h, (2) Remove + nuttx/binfmt/elf.h in libs/libc/machine, (2) Remove + nuttx/binfmt/elf.h in modlib, and (4) Rmove nuttx/module.h in + modlib. From Xiang Xiao. + - ELF Executables: If there is an address environment + (CONFIG_ARCH_ADDRENV), binfmt/elf doesn't need to free ctor/dtor + alloc since freeing the address environment releases the heap + automatically. From Xiang Xiao. + - ELF Configuration: Correct libcxx exception handling by + introducing the generic config(CXX_EXCEPTION and CXX_LIBSUPCXX) + From Xiang Xiao. + - ELF Loaders: Call umm_initialize as soon as possible otherwise + elf_loadctors/elf_loaddtors may fail to allocate memory. From + Xiang Xiao. + + * Crypto: + + - Crypto AES: After NuttX 7.28 crypto/aes.c would no longer + compile. From Gregory Nutt. + + * File System/Block and MTD Drivers: + + - open(): Fix not returning failure for block_proxy() call. From + David Sidrane. + - AIO: aio_cancel() needs to signal caller after success. Also fix + minor issue in the error handler. From Xiang Xiao. + - HostFS: Remove the unnecessary use of host_stat() in + hostfs_bind() From ligd. + - LittleFS: Fix a minor issue found in code review: (1) Replace + printf to finfo/fwarn/ferr, (2) Replace malloc/free to + kmm_malloc/kmm_free, (3) define LFS_NAME_MAX to NAME_MAX, (4) Check + the big endian using CONFIG_ENDIAN_BIG. From Xiang Xiao. + - LittleFS: VFS Lookahead should use bit unit not byte unit. From + Xiang Xiao. + - NxFLAT: Correct a double free debug assertion. This occurs when + groups are enabled: (1) once via binfmt_exit and unload_module, + and (2) once via sched_releasetcb(). this was corrected by adding + logic to free/unload the memory once and nullify the pointer so + that cannot be freed a second time. This commit resolves Bitbucket + issue #145. From Valmantas Palika. + - NxFLAT: File descriptor leaks when nxflat loading fails. From + Valmantas Palika. + - ProcFS: Fix typo in procfs uptime logic. From Sebastien Lorquet. + + * Networking/Network Drivers: + + - Network Configuration: The setup seems to support a network + without sockets (CONFIG_NSOCKET_DESCRIPTORS == 0). That is not the + case; if the network is enabled, sockets must be provided. From + Gregory Nutt. + - Networking: The value ERROR should never be returned from internal + OS functions. That is reserved for returning values to appliations + with the errno value set. Within the OS, errors are returned with + a negated errno value ALWAYS. From Gregory Nutt. + - Networking: The struct in_addr doesn't have the member sin_addr. + The function lib_lo_ipv6match() is for IPv6. Correct the function + it calls from lib_lo_ipv4matchto() to lib_lo_ipv6match(). Also add + CONFIG_NET_IPv6 for configuration. From Kejun ZHOU. + - TCP (buffered) send: Fix assertion crash when window size is + zero. From Gregory Nutt. + - ICMP/ICMPv6: Bind icmp callback from device to connection. + Resolves the issue that bind() could not be called before send() + From anchao. + - TUN/TAP Driver: Re-order all TUN/TAP driver state data. Not only + was was with wasting memory due to alignement requirements, it was + also causing network packet buffers to be improperly aligned + causing problems because the network requires 16-bit packet buffer + alignment for uint16_t accesses. This alignment problem was + discovered by Alan Carvalho de Assis. From Gregory Nutt. + - TUN/TAP Driver: Packet buffer size should include the configured + GUARD_SIZE. And, given how the buffers are allocated, the + allocation size must be an even number of 16-bit values to preserve + alignment. From Gregory Nutt. + - Local Sockets: In local_connect(), initialize lc_result before + giving lc_waitsem From zhangyuan7. + - Local Sockets: Fixed deadlock issue by replacing nxsem_wait() with + net_lockedwait() so that we do not wait with the network locked. + From zhangyuan7. + + * Graphics/Display Drivers: + + - NX Graphics: Remove naming associated with the now non-existent + NXFE graphics layer: Rename nxfe_reportposition to + nxmu_reportposition. Rename nxfe_redrawreq to nxmu_redrawreq. + Rename nxfe.h to nxmu.h. Rename nxfe_state_s to nxmu_state_s. + Rename nxfe_conn_s to nxmu_conn_s. From Gregory Nutt. + - NxTERM: Remove the nxterm_unregister interface. The correct way + to unregister a device is to unlink it. From Gregory Nutt. + - NxTerm: Needs to clear display initially. Otherwise, garbage from + previous display may still be present from preceding NxWM window. + From Gregory Nutt. + - Font Cache: Fix a memory leak in the font cache. With a busy + NxTerm display, this could drain off all the memory pretty quickly! + From Gregory Nutt. + - Graphics: Nothing under graphics/ should set the errno. From + Gregory Nutt. + - Graphics: Fix a coordinate system error in nx_filltrapezoid(). + When no clipping rectangle is falls, it falls back to use the + entire window as for the clip. However, that window must then then + be in window relative coordinates, not in absoute device + coordinates. From Gregory Nutt. + + * Common Board Logic: + + - boardctl(): Fix compiling error when set + CONFIG_BOARDCTL_IOCTL/CONFIG_BOARDCTL_UNIQUEID. From Kevin Liu. + + * Common Drivers: + + - INA3221: Fix errors in INA3221 register field addresses and + bitfield values. Signed value was losing its signed-ness due to + use of unsigned type for register. From Ken Pettit. + - Serial Upper Half: Initialize OPOST and ONLCR in uart_register. + From Xiang Xiao. + - Serial Upper Half: Don't reset the circular buffer on close since + DMA may still be transferring data in the background if the user + closes the handle too quickly and the handle is opened with + O_NONBLOCK. From Xiang Xiao. + - 16550 UART: Fix error: 'g_uart0port' undeclared. From Xiang Xiao. + - 16550 UART: Fix typo for UART1 flow field initialization From + Gregory Nutt. + - CDC/ACM HCD: Fixes to the IOCTL method in recovery of UART pointer + and in names of Termios-related field. From xhbm. + - USB Device: Fix type for USBDEV_TRACE_INITIALIDSET in Kconfig. + From Mateusz Szafoni. + - TCA64xx: Fix some errors in the TCA64XX driver. From Bruno + Schwander. + - SYSLOG RAMLog: Fix error: Conflicting types for 'ramlog_addchar' + From Xiang Xiao. + - NRF24L01: Fix uninitialized irq_work which was causing a + hard_fault on interrupt handler whenever something was sent from + nrf24l01_term From Petri Ahonen. + - MCP2515: Use kmm_zalloc to allocate device state structure. Fix + some compiler errors. From Valmantas Paliksa. + + * Architecture Common: + + - arch/ Common: Remove architecture-specific watchdog.h and + arm-elf.h because they are empty. The arm-elf header file was + never used; the empty watchdog.h header file was used in only one + place. From Xiang Xiao. + - arch/ Common: Move up_pminitialize() after timer_initialize() + From ligd. + - arch/ Common: Align semi-hosting call style with other syscalls in + architecture-specific syscall.h. From Xiang Xiao. + - arch/ Common: Every file that uses serial IOCTLs (TIOC*) must + explicity include nuttx/fs/ioctl.h. This was included previously + via sneak path in the now deleted arch/serial.h. From Gregory Nutt. + - arch/ Interfaces: Rename sched_process_cpuload to + nxsched_process_cpuload. All internal sched_ functions should be + prefixed with nx. From Valmantas Paliksa. + + * ARMv7-A: + + - ARMv7-A MMU: Updating the cp15_wrttb and cp15_wrdacr functions to + use inline assembly in the correct way. The incorrect method was + generating errors as ARMv7-a expects the MCR/MRC instructions to + provide registers as an argument(MRC p15, 0, , c2, c0, 0) and + the code was providing a constant value(and hence the build + error). From Bilal Wasim. + - ARMv7-A: Remove inclusion pg_macros.h for armv7-a since this + header file does not exist. From zhangyuan7. + - ARMv7-A: Guard some assembly files if configuration not selected. + From zhangyuan7. + - ARMv7-A GIC: Fix assemble error when including gic.h From Xiang + Xiao. + - ARMv7-A GIC: Don't use GIC_ICDDCR_ENABLEGRP1 for GIC NONSECURE + since this bit doesn't exist in this mode. From liuzhuang. + + * ARMv7-R: + + - ARMv7-R Syscall: In arch/arm/include/syscall.h, add missing + inclusion of arch/armv7-r/syscall.h for Cortex-R. From Xiang Xiao. + + * ARMv7-M: + + - ARMv7-M Initialization: As noted by Roland Takacs in Bitbucket + issue 141, there is a compilation error for STM32 if CONFIG_NET and + CONFIG_NETDEV_LATEINIT are selected. That was due in part to the + commit which extended up_netinitialize() with a + !defined(CONFIG_NETDEV_LATEINIT) guard but did not add the guard to + concrete implementations. I say "in part" because I don't think + that the original intent of commit 19e16cb was to enable an + alternative initialization of MCU internal Ethernet support but + rather to enable support of external Ethernet devices that may have + dependencies on, for example, SPI. However, this is still a proper + fix to avoid the compilation error that can occur with this + combination of configuration options. From Gregory Nutt. + - ARMv7-M Configuration: ARCH_HIPRI_INTERRUPT shouldn't select + ARMV7M_USEBASEPRI. First because that is a violation of the + layered nature of the Kconfig architecture, but also because then + Kconfig will generate errors when high priority interrupts are used + with other architectures. From Xiang Xiao. + - ARMv7-M Vector Table: Make the default NVIC_VECTAB_TBLOFF_MASK + safer. The base address of the new vector table must be aligned to + the size of the vector table extended to the next larger power of + 2. From Xiang Xiao. + - ARMv7-M RAM Vectors: Correct bad NVIC_VECTAB_TBLOFF_MASK + definitions in previous commit. Were missing bits in the mask. + Raised DEBUGASSERT in armv7-m/up_ramvec_initialize.c line: 144. + From Mateusz Szafoni. + + * Expressif ESP32 Drivers: + + - ESP32 Timer ISR: Fix backward comparison. From Gregory Nutt. + - ESP32 Serial: Fix some backward arguments. Correct 2-stop bit + setting. From Gregory Nutt. + + * Microchip/Atmel SAMD2x/L2x Drivers: + + - SAMD2/L2 Serial: SAMD2/L2 serial driver. It needs + sam_usart_enable(). to work From Alan Carvalho de Assis. + + * Microchip/Atmel SAMD3/4 Drivers: + + - SAM3/4 Ethernet: Port Anthony Merlino's SAMv7 fix to similar + Ethernet driver for the SAM3/4. From Gregory Nutt. + + * Microchip/Atmel SAMV7 Drivers: + + - SAMv7 SPI: Fix DMA Tx/Rx timeout issue. From Kevin Liu. + - SAMv7 QSPI: Compile error when set CONFIG_SAMV7_QSPI_DLYBCT. + From Kevin Liu. + - SAMv7 Ethernet: The logic for determining the number of queues for + SAMV71 must be extended. All SAMv7 parts increase the number of + queues from 3 to 6 at revision B, not just the SAMV71. From + Gregory Nutt. + - SAMv7 Ethernet: Fixes rxdesc index logic to handle Buffer Not + Available (BNA) condition. If a SOF is found, but no EOF, don't + move past the frame. Instead, keep the index at the SOF buffer + until the rest of the data is written. This fixes a receiver + lockup condition where the peripheral and this driver get out of + sync with there head pointers. In this case the driver has moved + past buffers it owns, without clearing ownership, which results in + the peripheral and driver in a deadlock with each other. From + Anthony Merlino. + + * Microchip/Atmel SAMA5Dx Drivers: + + - SAMA5Dx Ethernet: Port Anthony Merlino's SAMv7 fix to similar + Ethernet driver for the SAMA5Dx. From Gregory Nutt. + + * Microchip/Atmel SAMA5Dx Board: + + - SAMA5D2-XULT: Move console from FLEXCOM4 to UART1. FLEXCOM4 does + not work for the Arduino serial. UART1 is used with the VCOM + provided by the EDBG. From Gregory Nutt. + + * NXP i.MXRT: + + - i.MXRT Clock Configuration: If SDRAM is actived it was only + running at 40MHz. This was becaus imxrt_clockconfig.c changed the + SEMC clock divider after the DCD was configured. This commit + corrects that. From Johannes. + + * NXP i.MXRT Drivers: + + - i.MXRT GPT: Correct register offsets. From David Sidrane. + - i.MXRT TMR: Fix addressing and restructure using common offset. + From David Sidrane. + - i.MXRT ADC: Error in offset. From David Sidrane. + + * NXP/Freescacle Kinetis Boards: + + - Teensy-3.x: Fix a mismatch in types in defconfig. From Gregory + Nutt. + + * NXP LPC17xx: + + - LPC176x Clock Configuration: The code preserves undocumented + reserved bits only if board does not set them to keep previous + behavior for boards where developers (hopefully) know what values + should be set into these bits. From Pavel Pisa. + - LPC17xx Clock Configuration: The enable of EMC clocks has to be + preserved when already enabled by loader. EMC and related pins + configuration has to be skipped if the system is run from SDRAM. A + region of SDRAM which is used by system must not be used for heap. + From Pavel Pisa. + + * NXP LPC17xx Drivers: + + - LPC17xx CAN: The name can_txready clashes with Nuttx CAN core + global function. LPC178x has only single LPC17_SYSCON_PCLKSEL with + only single divisor. From Pavel Pisa. + + * NXP LPC17xx Boards: + + - Open1788: Add missing MPU configuration option. From Gregory Nutt. + + * On Semi LC823450 Boards: + + - LC823450-XGEVK: Remove -nostdinc to avoid build error From + Masayuki Ishikawa. + + * STMicro STM32: + + - STM32: Don't try including stm32_gpio.h from within chip/*.h + header files. Not only is bad style for a layered inclusion + system, but it doesn't always work. From Gregory Nutt. + + * STMicro STM32 Drivers: + + - STM32 PWM: Fix polarity and IDLE state configuration From Mateusz + Szafoni. + - STM32 ADC, PWM and TIM: (1) missing T1TRGO2 for JEXTSEL, (2) fix + sample time configuration for channels. The array index for + channels was missing, (3) fix TRGO/TRGO2 configuration, and (6) + support for advanced timers channel 5 and 6. From Mateusz Szafoni. + - STM32 Heap: Change 'if CONFIG_STM32_HAVE_CCM' to 'ifdef + CONFIG_STM32_HAVE_CCM' to avoid a warning when + CONFIG_STM32_HAVE_CCM is not defined. From Gregory Nutt. + - STM32 Oneshot Timer: Fix an error introduced be a previous timer + commit. From Maximilian Kriegleder + - STM32 Tickless Mode and Free-Running Timer: Apply Max's + stm32_oneshot.c fix to the tickless implementation and to the + freerunning time. From Mateusz Szafoni. + - STM32 PWM: Set CCPxP and CCPxNP bits if polarity is negative. + Missing commas in initializers could break compilation in certain + configurations. From Mateusz Szafoni. + - STM32F7 Interrupts: Add the missing macro STM32_IRQ_NIRQS used by + arch/arm/src/stm32f7/stm32_irq.c. From Kejun ZHOU. + - STM32H7 DMA: Fix AHB1 base adresses memory map. From Mateusz + Szafoni. + - STM32H7 SysTick: H7 appears to ignore the SysTick CLKSOURCE bit + and use the CPU clock in all cases. From Mateusz Szafoni. + + * STMicro STM32 Boards: + + - B-L072Z-LRWAN1: Fix typo in SPI1 pin definitions. From Mateusz + Szafoni. + - STM32F429I-DISCO: Handle multiple calls to the LCD + up_fbinitialize() function. From Gregory Nutt. + - STM32F769I-DISCO: Florian R. Hlzlwimmer reports that + stm32_appinitialize.c often has missing OK and NULL definitions. + This should be fixed by including sys/types.h where they are + defined. From GregoryN. + - STM32F769I-DISCO: Remove CONFIG_STM32F7_QUADSPI=y from the + configuration. This was apparently set before the implementation + was added. Now that the implementation was added, the configuration + will not build because it requires that QSPI GPIO pin definitions + be provided in the board.h header file. From Gregory Nutt. + + * TI AM335x Drivers: + + - AM335x Serial: Eliminate an error 'TIOCSBRK undeclared. From + Gregory Nutt. + + * C Library/Header Files: + + - strto*: In alll strto* function family, did't consume single '-' + or '+', allow sign in strotul(l)). From Johannes. + - getopt(): Add logic to reinitialize the stale context for the + FLAT/PROTECTED builds. In these builds getopt() global variables + may be shared by many tasks. If any task exits the getopt() loop + before all command line arguments have been parsed, then getopt() + global variables will be left in a bad state. The next time + getopt() is called, this logic should detect the bad state and + force the state of getopt() to be re-initialized so that it can be + reused. This logic is not full proof (it would fail, for example, + if you tried to parse the same command line twice) but should catch + the typical misuse cases. From Xiang Xiao. + - sscanf(): Initialized the lastc pointer to avoid the checks for + NULL. Removed a bug in the floating point parsing which allowed + several signs after each other. From Johannes. + - lib_vsprintf() (Legacy): No precision specifier resulted in + precision 0 but should be precision 6. From Johannes. + - lib_vsprintf() (Legacy): Correct justification for alternate forms + of %p and %P From ligd. + - lib_vsprintf() (Nano): Add long long support. + CONFIG_LIBC_LONG_LONG needs at least CONFIG_NANO_PRINTLEVEL 2. + Code size for compile without CONFIG_LIBC_LONG_LONG shouldn't be + affected. From Johannes. + - lib_vsprintf() (Nano): Remove CONFIG_LIBC_PRINT_MINIMAL. The + output in that configuration is unsatisfactory and inappropriate + for use with NuttX. For example, the output from many NSH commands + become corrupted and useless. Doesn't belong in this context. + From Gregory Nutt. + - libs/libc/symtab: Remove unused symtab_findorderedbyvalue(). From + Xiang Xiao. + - libs/libc/machine/arm: Fix the minor issue in libc arm machine + folder; MOVW/MOVT should use zero(not sign) extension. From Xiang + Xiao. + - libs/libc/libc.csv: Should be locale.h not local.h. From Joao + Matos. + - libs/libc/libc.csv: Needed logic for correct compilation if not + using CONFIG_LIBC_WCHAR. From Joao Matos. + - libxx: Always include libxx_cxa_guard.cxx in the build for for + uclibcxx. From zhangyuan7. + + - include/stdbool.h: Define bool only when __cplusplus isn't + defined. From Xiang Xiao. + - include/nuttx/list.h: Added a Linux-compatible list + implementation. From zhuyanlin. + - include/nuttx/irq.h: Fix enter_critical_section/spin_lock_irqsave + macro typo error and remove the duplicated inclusion of + arch/irq.h. From Xiang Xiao. + - include/dlfcn.h: Correct naming of standard header file. Should + be dlfcn.h, not dllfcn.h. From Gregory Nutt. + - include/nuttx/nx/nxmu.h: This header file could be lethal; it + declared an #error if CONFIG_DISABLE_MQUEUE=y. From Gregory Nutt. + - include/nuttx/compiler.h: Important fix for C++ users. + compiler.h was using the value of __STDC_VERSION__ to determine if + inline functions are supported or not. If not then the keyword + inline was defined out. Good for C but bad for C++ because C++ + does not define __STDC_VERSION__ at all. C++ applications may + draw in compiler.h indirectly via other head files and this can + result in C++ compiler problems since 'inline' is defined out. + This fix is to ignore the (undefined) __STDC_VERSION__ if + __cplusplus is defined. From Gregory Nutt. + - include/nuttx/elf.h: Adds missing extern "C" __cplusplus guard. + From Anthony Merlino. + - include/poll.h: Remove un-named union from 'struct pollfd'. It + is not required by OpenGroup.org and violates the NuttX C coding + standard because it is not C89 compatible. From Gregory Nutt. + - libs/libc/Makefile, libs/libnx/Makefile, and mm/Makefile: Remove + obj-path MKDEPS option since make dependency target (MT) is not + supported by some toolchains. From anchao. + - include/nuttx/compiler.h: Assume inline support if + __STDC_VERSION__ not defined. From Xiang Xiao. + + * Tools: + + - tools/convert-comments.c: Fix an error in handling of a blank C++ + comment before a comment block. From Gregory Nutt. + - tools/lowhex.c: Fix an initialization problem that was causing + some odd behavior at the beginning of lines. From Gregory Nutt. + - tools/nxstyle.c: Fix logic that detects if an operator is + correctly delimited with spaces. sched/: Various changes because + sched/ C files were used as Guinea Pigs to test nstyle.c. From + Gregory Nutt. + - tools/nxstyle.c: Was confusing hex constants with strings staring + with 'x'. Added logic to complain about hex constants containing + upper case characters. From Gregory Nutt. + - tools/nxstyle.c: Fix logic error that prevent detecion of '/' and + '/=' as operators. net/: Minor updates resulting from testing + tools/nxstyle. From Gregory Nutt. + + * NSH Library: apps/nshlib: + + - NSH Console: Fix copy paste errors. Some Kconfig configuration + names needed CONFIG_ prefix. From David Sidrane. + - nshlib/nsh_timcmds.c: Uninitialized struct tm caused 'date -s' to + fail. From Valmantas Palika. + + * Examples: apps/examples: + + - apps/examples/nxterm: Replace direct calls to nxtk_register() + with legal, indirect calls via boardctrl(BOARDIOC_NXTERM). + Replace calls to (deleted) nxterm_unregister(). The correct way + to delete a driver is by unlink'ing it. From Gregory Nutt. + - apps/examples/nxterm: Most configuration options were not + available in the Kconfig file. From Gregory Nutt. + - apps/examples/nxterm: Replace illegal direct calls to + nxterm_redraw() and nxterm_kbdin() with new boardctl() calls. + From Gregory Nutt. + - apps/examples/nxterm: NxWM passed the size of the NxTK sub-window + but nxterm example passed the size of the complete NxTK window. + They must be made consistent. From Gregory Nutt. + + * Graphics Utilities: apps/graphics: + + - apps/graphics/NxWidgets/nxwm: Correct an error in the type of the + return value in CCalibration. From Gregory Nutt. + - apps/graphics/NxWidgets/nxwm: Replace direct calls to + nxtk_register() with legal, indirect calls via + boardctrl(BOARDIOC_NXTERM). Replace calls to (deleted) + nxterm_unregister(). The correct way to delete a driver is by + unlink'ing it. From Gregory Nutt. + - apps/graphics/NxWidgets: Replace illegal direct calls to + nxterm_redraw() and nxterm_kbdin() with new boardctl() calls. + From Gregory Nutt. + + * Modbus: apps/modbus: + + - apps/modbus/Kconfig: Fix modbus master Kconfig. Modbus Master + ASCII compiles correctly. From Alan Carvalho de Assis. + + * Network Utilities: apps/netutils: + + - apps/netutils/dhcpc/dhcpc.c: Fix an error for DHCP REQUEST + receiving a NAK.In DHCP Request operation, no need to update + ciaddr to the client address and keep it as 0. From Kevin Liu. + + * System Utilities: apps/system: + + - apps/system/vi/vi.c: Fix an infinite loop bug that can show up in + some cases (plus a couple of other items). From Ken Pettit. + - apps/system/vi: Condition KEY_CMDMODE_REPEAT with + CONFIG_SYSTEM_VI_INCLUDE_COMMAND_REPEAT to avoid build error when + option is not selected. From Anthony Merlino. + - apps/system/nxplayer/nxplayer.c: Fix build error when only enable + CONFIG_AUDIO_EXCLUDE_VOLUME is enabled. From ZhongAn. + - apps/system/system/system.c: Correct a path name. From anchao. + - apps/system/taskset: Fix command arguments are not passed. From + Masayuki Ishikawa. + + * Testing: apps/testing: + + - apps/testing/ostest/timedmutex.c: pthread_mutex_timedlock() + returns EDTIMEDOUT on a timedout, not EAGAIN. From Gregory Nutt. + + * Tools: apps/tools: + + - apps/tools/mksymtab.sh: 'export LC_ALL=C' to get the traditional + sort order From anchao. + +NuttX-7.30 Release Notes +------------------------ + +The 130th release of NuttX, Version 7.30, was made on May 19, 2019, +and is available for download from the Bitbucket.org website. Note +that release consists of two tarballs: nuttx-7.30.tar.gz and +apps-7.30.tar.gz. These are available from: + + https://bitbucket.org/nuttx/nuttx/downloads + https://bitbucket.org/nuttx/apps/downloads + +Both may be needed (see the top-level nuttx/README.txt file for build +information). + +Additional new features and extended functionality: + + * Core OS: + + - pthreads: Added non-standard pthread_get_stackaddr_np() and + pthread_get_stacksize_np(). From Joao Matos. + - boardctl(): Add a command to start the VNC server. From Gregory + Nutt. + - Signals: Remove references to CONFIG_DISABLE_SIGNALS in many + files. Signals can no longer be disabled. From Gregory Nutt. + + * Wireless/Wireless Drivers: + + - NRF24L01: Add support for "multicast" TX mode - no waiting for ACK + (needs to be enabled with fcntl SETTXPAYLOADNOACK) From Leif Jakob. + + * Graphics/Display Drivers: + + - NX Graphics: Add new server->client callback to notify the window + client of server events. Remove the old 'blocked' callback and just + make it one case of an 'event' callback. From Gregory Nutt. + - NX Graphics: Implement new interfaces nx_synch() and nxtk_synch(). + This are used to synchronize the NX server with the window client. + Currently most of the logic is equivalent to nx_block() and + nxtk_block(), but with slightly different semantics. They are + separate now because they are likely to diverge in the future. + From Gregory Nutt. + - NX Graphics: Add support for modal windows. From Gregory Nutt. + - NX Graphics: Implement a software cursor. The cursor behaves + like a "sprite", always at the top of the display with a + transparent background. Includes new NX interfaces to show/hide + the cursor, set the cursor image, and to move the cursor position. + From Gregory Nutt. + - NX Graphics: Added support for hiding windows. This features is + needed by Twm4Nx: When a window is iconified, the icon should + appear on the background and the window should disappear (i.e., be + hidden). The windows needs to remain healthy and to be updated in + all ways, but it cannot affect the display content. Conversely, + when the icon is clicked, the icon needs to be hidden on the + background and the window needs to be restored in its current + state (which may be different than the state of the window at the + time it was iconified. From Gregory Nutt. + - NX Graphics: Windows can now be created in the hidden state. + This can be used to clean up initial window presentation which may + involve several steps. This makes those steps all invisible until + nx[tk]_setvisibility() is called to make the windows visible. + From Gregory Nutt. + - NX Graphics: Add new NX interfaces to query if a window is hidden + or not. From Gregory Nutt. + - NxTerm IOCTLs: Replace specific interfaces between boardctl and + nxterm with a generalized IOCTL interface. From Gregory Nutt. + - NxTerm: Add a new IOCTL that can be used to inform NxTerm that + the size of a window has changed. From Gregory Nutt. + + * Other Common Device Drivers: + + - CAN Upper Half: Support multiple readers of the same port From + Valmantas Paliksa. + - MAX7456: Adds a read-only (for now) /dev/osd0/CM interface for + obtaining the chip's onboard NVM character map data. Use seek() + to position the cursor over a desired subset of bytes, or request + a large read to obtain the entire EEPROM memory contents. Values + are returned in binary form. Use hexdump, etc. to format them for + viewing. From Bill Gatliff. + - Serial Upper Half: The upper half serial driver configuration + CONFIG_SERIAL_DMA used to enable DMA on both RX and TX streams. + This was replaced with CONFIG_SERIAL_RXDMA and CONFIG_SERIAKL_TXDMA + which will permit supporting DMA on only one or both streams. + From Gregory Nutt. + - FUSB303: Add FUSB303 driver From Juha Niskanen. + + * Microchip PIC32MZ Drivers: + + - PIC32MZ GPIO: Adds support for edge detect mode. Slew Rate was + also added for completeness. From Abdelatif Guettouche. + + * Microchip/Atmel SAMv7 Boards + + - SAME70-xplained: Add a configuration for test Twm4Nx using VNC. + From Gregory Nutt. + + * Microchip LPCxx Drivers: + + - LPC17xx Ethernet: Added support for KSZ8081RNA PHY to LPC17xx + Ethernet driver. From jjlange. + - LPC17xx Ethernet: Added support for Ethernet PHY ioctl() on + LPC17xx. From jjlange. + + * NXP i.MX RT: + + - .i.MXRT1020: Gets imx1020 family support started. It is pretty + similar, but subtly different, to 1050/60 (less PLLs, less GPIO + banks, differently numbered ports etc. etc.). + + Moved each of the imxrt family-specific files into its own + subdirectory to tidy things up a bit, and remove the vast majority + of ifdefs from the mainline code. + + From Dave Marples. + + * NXP LPC54xx Drivers + + - LPC54xx USB FS Host: Bring in the USB FS OHCI driver from LPC17. + This is a quick'n'dirty port from LPC17 that I hope finish + sometime later. Currently, it is missing hardware clocking setup + and is not even hooked into the build system yet. From Gregory + Nutt. + + * NXP LPC54xx Boards + + - LPCXpresso-LPC54628: Add a Twm4Nx configuration. From Gregory Nutt. + + * Sony CXD56xx + + - CXD56xx: Add initial CXD56xx chip driver sources. From Nobuto + Kobayashi. + + * Sony CXD56xx Spresense Board + + - Spresense: Add Spresense board support. This is not the full + Spresense BSP from Sony, only the barebones logic to present an + NSH console. From Nobuto Kobayashi. + + * STMicro STM32: + + - STM32F7 Clocking: Add support for using the HSE in bypass mode, + configured by board.h From Anthony Merlino. + - STM32F7 Clocking: Added support for TICKLESS mode. From Valmantas + Paliksa. + - STM32H7 Backup Domain: Add backup domain control registers. From + Jukka Laitinen. + - STM32H7 Clocking: Set the STM32H7 default HSI pre-divider to 4. + The I2C driver currently assumes HSI clock to be 16MHz. From Jukka + Laitinen. + - STM32H7 Memorymap.: Add the STM32H7 SYSTEM_UID and DEBUGMCU_BASE + register definitions. From Jukka Laitinen. + - STM32L071x: Add support for STM32L071x. From Mateusz Szafoni. + + * STMicro STM32 Drivers: + + - STM32 OTGHS Host: Allow VBUS monitoring for the OTG_HS host + driver. From Jason Harris. + - STM32F0/L0 ADC: Initial ADC support for the STM32 M0 From Mateusz + Szafoni. + - STM32F0/LO I2C: Port STM32F7 I2C to STM32F0/L0, From Mateusz Szafoni. + - STM32F1 FLASH: As noted by Matias N, the FLASH base address used + was incorrect. It was using the address of the FLASH data, not + the address of the FLASH registers. From Gregory Nutt. + - STM32F3 I2C: Port STM32F7 I2C to STM32F3. From Mateusz Szafoni. + - STM32F7 Ethernet.c: Auto-generate Ethernet MAC address from + device unique ID. From Valmantas Paliksa. + - STM32F7 FLASH: Add flash block mapping support for progmem. From + Valmantas Paliksa. + - STM32F7 FMC: Updated stm32_fmc.h with more FMC definitions. From + Joao Matos. + - STM32F7 GPIO: Adds additional pin alternate function for SPI2. + From Anthony Merlino. + - STM32F7 PWM: Ported the PWM from F4 to F7. From Eduard Niesner. + - STM32F7 SDMMC: Support bypassing the input clock divider on the + SDMMC interface. This enables using the full clock speed provided + to the SDMMC interface with no dividing. From Anthony Merlino. + - STM32F7 SPI: Add SPI DMA threshold configuration. From Valmantas + Paliksa. + - STM32F7 UID: Add UID access. From Valmantas Paliksa. + - STM32F7 USB: USB High speed for STM32F7 series From Ramtin Amin. + - STM32H7 Ethernet: Add stm32h7 Ethernet driver. This is the + initial push for the Ethernet driver. The driver has been tested + to be working on a nucleo board. This is still WIP, it doesn't + for example do MAC filtering on HW level, but just receives all + Ethernet packets. From Jukka Laitinen. + - STM32H7 GPIO: Add the GPIO_ETH_RMII_RXD1 pinmap definition for + STM32H7. From Jukka Laitinen. + - STM32H7 SDMMC: Add STM32H7 SDMMC driver. It is mostly copied + from STM32F7, with modified register addresses and bits, and IDMA + dded. This is still WIP; it only works with IDMA. From Jukka + Laitinen. + - STM32H7 Timers: Add timer devices driver for STM32H7. This i + mostly a forklift from stm32f7 with some h7 specific + modifications. From Jukka Laitinen. + - STM32L0 AES: Add support for AES for L0. From Mateusz Szafoni. + - STM32L0 RND: Add support for RND. From Mateusz Szafoni. + - STM32L0 HSI48: Add support for HS148 for L0.

From Juha + Niskanen. + - STM32L4 HSI48: Port HSI48 from STM32F0/L0 From Juha Niskanen. + - STM32L4 CRS: Port CRS from STM32F0/L0 From Juha Niskanen. + + * STMicro STM32 Boards: + + - B-L072Z-LRWAN1: Add ADC example. From Mateusz Szafoni. + - B-L072Z-LRWAN1: Add nxlines_oled example (ssd1306). Add support + for the I2C tool From Mateusz Szafoni. + - Nucleo-144: Added STM32_RCC_DCKCFGR2_DSISRC definition to board.h. + From Joao Matos. + - Nucleo-144: Mount sysfs for ifconfig for f767-netnsh/defconfig. + Even if ifconfig is working to set IP, it will not work to display + NICs (without args) From Phil Coval. + - Nucleo-144: Add basic PWM support to nucleo-144 board. More PWMs + and multi channels support may be investigated and added later. + Tested on Nucleo-F767ZI. From Phil Coval. + - Nucleo-F303ZE: Add nxlines_oled example (ssd1306) From Mateusz + Szafoni. + - Nucleo-H743ZI: Enable the FPU. From Jason Harris. + - Nucleo-H743ZI: Add support for I2C devices: ssd1306, pca9635, + i2ctools From Mateusz Szafoni. + - Nucleo-H743ZI: Add default clock configuration for SDMMC for + Nucleo-H743ZI's board.h. From Jukka Laitinen. + - Nucleo-H743ZI: Add the input clock frequency definitions in + board.h for all the drivers. Assumes internal clock source for + all the timers. From Jukka Laitinen. + - STM32F4 Discovery: Keep c++ global constructor symbols From + Masayuki Ishikawa. + - Nucleo-L073RZ: Add MFRC522 support From Mateusz Szafoni. + - OmnibusF4: Add boardctl() reset logic. From Bill Gatliff. + - OmnibusF4: Add board_ioctl() which is needed only if + CONFIG_BOARDCTL_IOCTL=y is selected; Update NSH configuration + to enable board IOCTLs and DFU mode reset. From Bill Gatliff. + - STM32L Discovery: Add support for board_late_initialize(), Move + common initialization logic out of board_app_initialize() into new + file stm32_bringup.c From Gregory Nutt. + - STM32F103-Minimum: Add PROCFS automount support From Alan + Carvalho de Assis. + + * Libraries/Header Files: + + - include/alloca.h: Add alloca.h. Included limited implementation + of alloc() that is only available for GCC versions 3 and above. + From Joao Matos. + - include/cxx/cstdlib: Add std::random() From Gregory Nutt. + + * apps/ General: + + - Many locations: Remove references to CONFIG_DISABLE_SIGNALS. + Signals can no longer be disabled. From Gregory Nutt. + + * Examples/Tests: apps/examples: + + - apps/examples/fb: Add some awareness of overlays to + apps/examples/fb From Matthew Koch. + - apps/examples/lvgldemo. Update to Littlevgl 5.3. From Matthew + Koch. + - apps/examples/pwfb: Extend example to verify software cursors. + From Gregory Nutt. + - apps/examples/pwfb: Add options to reduce the number of windows. + This is helpful during debug to reduce the complexity. From + Gregory Nutt. + + * Network Utilities: apps/netutils: + + - apps/netutils/cjson: Support for the current version of cJSON. + From Mateusz Szafoni. + - apps/netutils/libcurl4nx: This is an initial commit libcurl4nx. + It is not complete yet, but I still wish to commit the unfinished + bits to describe the roadmap, and because it is already usable. It + will be updated and fixed in the future weeks and months, certainly + including POST support and later, SSL. From Sebastien Lorquet. + - apps/netutils/netinit. This commit removes the private network + initialization logic from NSH and puts in a common location at + apps/netutils/netinit. Now that netork initialization logic can be + used by applications that do not include NSH. From Gregory Nutt. + - apps/netutils/netlib: Add a more flexible version of + netlib_parsehttpurl(). This one can parse any URL, and is + extensible so future improvements keep the same API. From Sebastien + Lorquet. + + * System Utilities: apps/system + + - apps/system/spi: I needed a small test tool for spi in the style of + the I2C tool, but I didn't see one so I've hacked one out of the I2C + tool source. From Dave Marples. + + * Graphics: apps/graphics: + + - apps/graphics/twm4nx. This release introduces Twm4Nx. Twm4Nx is a + "port" of TWM, Tab Window Manager (or Tom's Window Manager) version + 1.0.10 to NuttX NX windows server. No, a port is not the right + word. It is are-design of TWM from the inside out to work with the + NuttX NX server and NXWidgets. The name Twm4Nx reflects this + legacy. But Twm4Nx is more a homage to TWM than a port of TWM. + + The original TWM was based on X11 which provides a rich set of + features. TWM provided titlebars, shaped windows, several forms of + icon management, user-defined macro functions, click-to-type and + pointer-driven keyboard focus, graphic contexts, and user-specified + key and pointer button bindings, etc. + + Twm4Nx, on the other hand is based on the NuttX NX server which + provides comparatively minimal support. Additional drawing support + comes from the NuttX NxWidgets library (which necessitated a + conversion to C++). + + Twm4Nx is greatly stripped down and targeted on small embedded systems + with minimal resources. For example, no assumption is made about the + availability of a file system; no .twmrc file is used. + + The state of the "port" is available in + apps/graphics/twm4mx/README.txt. To summarize: The port is fully + functional but probably only at an alpha release level. The only + missing critical feature is built-in touchscreen calibration. + + - apps/graphics/littlevgl. Update to Littlevgl 5.3. From Matthew + Koch. + - apps/graphics/nxglyphs: Put all NxWidgets and NxWM glyphs into a + common directory where they can eventually be shared. Decouple + from nxwidgets and nxwm so that they can be used elsewhere. + Creates include/graphics/nxglyphs.h From Gregory Nutt. + - apps/graphics/nxglyphs: Add some new cursor bitmap images. From + Gregory Nutt. + - apps/graphics/nxglyphs: Add mkcursor.c. Will auto-generate + cursor image header file from Gimp C output. From Gregory Nutt. + - apps/graphics/nxglyphs: Add 16x16 cursor images. 30x30 are kind + of large on small displays. From Gregory Nutt. + - apps/graphics/nxglyphs: Add a new resize cursor image. From + Gregory Nutt. + - apps/graphics/nxwm: Separate NxWidgets and NxWM into separate + directories. Remove old, common NxWidgets directory. From + Gregory Nutt. + - apps/graphics/nxwm: Move the NxWM unit test main() to apps/nxwm. + It is no longer a unit test, but the main startup entry point for + NxWM. From Gregory Nutt. + - apps/graphics/nxwidgets: Update NX window clients so that they + use the new 'event' callback (vs. the obsoleted 'blocked' callback). + From Gregory Nutt. + - apps/graphics/nxwidgets: Add a synchronize method to every window. + This is a wrapper arounc nx[tk]_sync and permits C++ applications + to synchronize with the NX server. From Gregory Nutt. + - apps/graphics/nxwidgets: Add support for modal windows. From + Gregory Nutt. + - apps/graphics/nxwidgets: Add cursor control methods to the + CNxServer class. From Gregory Nutt. + - apps/graphics/nxwidgets: Add a method to CButtonArray that will + allow us to dynamically resize the array (at the cost of losing all + button labels). From Gregory Nutt. + - apps/graphics/nxwidgets: Fix a possible deadlock condition when + waiting for window geometry data that will never come. Fixed by + re-requesting geometry data if we don't already have it. From + Gregory Nutt. + - apps/graphics/nxwidgets: Add handshake to + CWidgetControl::getWindowHandle() to avoid returning a NULL + handle. From Gregory Nutt. + - apps/graphics/nxwidgets: CNxTkWindow, CNxWindow, CNxServer: Add + support to create RAM backed windows. From Gregory Nutt. + - apps/graphics/nxwidgets: Add methods to all windows to query if a + window is visible or hidden. From Gregory Nutt. + +Bugfixes. Only the most critical bugfixes are listed here (see the +ChangeLog for the complete list of bugfixes and for additional, more +detailed bugfix information): + + * Core OS: + + - Clock Initialization: A recent change broke Tickless mode for all + architectures. The original change was intended to handle the + case where up_timer_gettime may not start from zero case. The + side effect is that this changed to order of initialization of + clocking, breaking Tickless mode:: After this change the tickless + timer structures are used before they are initialized in + clock_inittime(). The commit has been reverted. + - pthread Stack Attribute: Fixed pthread_attr_get/setstacksize + param type to size_t. From Joao Matos. + - Signals: The abnormal termination signal handler was just calling + exit() conditionally when, for example, Ctrl-C is sent to a task. + The abnormal termination handler must obey the rules of cancellation + points: If cancelation is disabled, then the abnormal termination + logic must wait for cancelation to be re-enabled; If cancellation + is deferred then the abnormal termination logic may have to wait + for the victim task to enter or exit a cancellation point. From + Gregory Nutt. + - Syscall: Added support for munmap() syscall. From Joao Matos. + - Syscall: Fix a warning due to inconsistencies in return type in + syscall.csv. From Gregory Nutt. + - Syscall: Correct an error syscall.csv. Error occurred when + creating the munmap() proxy if CONFIG_FS_RAMMAP is not defined. + From Gregory Nutt. + + * File System/Block and MTD Drivers: + + - fs/littlefs/lfs.c: Fix lfs_format bug. In superblock disk root- + block assignment, the second must be root[1]. From YanLin Zhu. + + * Networking/Network Drivers: + + - getsockname(): Fix addrlen check in socket debug features. + Getsockname() checked erroneously a pointer agains 0, where the + intention was to dereference the pointer and to check the length. + This causes also a compilation failure if the code is compiled + with CONFIG_DEBUG_FEATURES and with -Werror flag set. From Jukka + Laitinen. + - Network Locking: net_lock() and net_restorelock() now return a + value. That values is the standard zero on success; negated errn + value on failure. This return value is only needed for + -ECANCELED. That cancellation indication needs to ripple all the + way back to the highest levels where the cancellation can be acted + on. This commit only adds the return value; it does not add + checking for the return values of net_lock() and net_restorelock() + at higher levels. That is required too. From Gregory Nutt. + - PHY Notification Driver: Change sprintf to strncpy in phy_notify. + On some platforms, the sprintf doesn't accept a const char* as a + format argument. From Jukka Laitinen. + - 6LoWPAN HC06: Correct an endian-ness problem in HC06 decompression. + From Ivan Ucherdzhiev. + + * Wireless/Wireless Drivers: + + - NRF24L01: Don't block in read if file descriptor is O_NONBLOCK. + From Leif Jakob. + + * Graphics/Display Drivers: + + - NX Graphics: Fix an error in coordinate system usage. Expected + rectangle in device coordinate frame, but was passing the + rectangle in window-relative coordinate frame. From Gregory Nutt. + - NX Graphics: Fix an oversight in the implementation of per-window + framebuffers. It is true that redraw callbacks can be suppressed + for all cases ... EXCEPT ONE: When the window is resized to a + larger size, then the newly exposed territory must be drawn for + the first time. From Gregory Nutt. + - NxTK: Fix an error in handling mouse events for framed windows. + When drawing, NX may report mouse positions outside of the Window. + The is only for NX windows, but the outside-the-side positions were + being discarded by nxtk_events(). From Gregory Nutt. + - NxTK: Refuse to open a toolbar of height zero or less. From + Gregory Nutt. + - Nxglib: Correct bogus logic in nxgl_interesting(). From Gregory + Nutt. + - VNC Server: Fix an error in color conversion. From Gregory Nutt. + + * Common Drivers: + + - APDS9960: Initial state of allocated structure was not being set. + Noted by Leif Jacob. From Gregory Nutt. + - MFRC522: In mfrc522_read uid.sak must be different from 0x04 not + as before from 0x00. SAK == 0x00 is a valid PICC type. Add + interface to read MIFARE Ultralight data From Mateusz Szafoni. + - Power: Fix build for battery gauge From Tom Kopriva. + - Syslog: In syslog buffered mode, avoid IOB alloc lock-up with + heavy network activity. This change alters the buffered syslog + logic to use 'iob_tryalloc' instead of blocking 'iob_alloc' to + avoid syslog printing from getting stuck when all IOBs are + depleted by network activity. An issue was seen when large + incoming TCP transfer uses free IOB buffers and processing + threads try to use syslog which then block at iob_alloc. From + Jussi Kivilinna. + - USB CDC/ACM Device: This fixes a problem where the host sent a + "get descriptor" message of type "standard" with a recipient of + type "interface". Since the composite driver would only pass + messages to the child interfaces when a message was not + "standard", this message was not handled. I changed the condition + so that the composite driver checks not only if this is a + "standard" message but if it is also directed to the device. + Otherwise, the handling is delegated to the children of the + composite device. From Matias N. + - USB HID: The usbhid_descriptor_s struct defined in hid.h included + some optional fields that should not be hard-defined as part of + that structure. An arbitrary number of optional entries could be + included in the descriptor, but that is not properly represented. + No code on NuttX currently depends on the structure definition + with an optional descriptor so it is safe to remove. From Matias N. + - USB MSC Device: Correct typo "const const" to "const". + arch/arm/src/stm32/stm32_i2s.c: In debug assertions, it on a + sample rate of 0, but based on other code comments this value + implies disabling the i2s master clock. From Jason Harris. + - Zerocross Driver: Fix some errors when debug assertions are + enabled. From Matous Pokorny. + - User Leds: Fix ledset validity check in ULEDIOC_SETALL ioctl. + From Jussi Kivilinna. + + * Architecture Common: + + - All board interfaces (those starting with board_) must be defined + in board-specific logic. Otherwise, they cannot be customized for + specialized usage by different boards. The board_reset() + interface was defined in architecture-specific logic that only + called up_systemreset(). That is useless! This change removes + the board_reset() implementation from the architecture-specific + code and re-implements it in the src/ directory of each board that + has CONFIG_BOARDCTL_RESET enabled. That is the correct functional + partitioning. From Gregory Nutt. + - Start-up: Remove dependency on CONFIG_ARCH_FPU for inclusion of + nvic.h in all other *_start.c files. From Gregory Nutt. + - Architecture initialization: up_initialize() needs to know about + ramlog_consoleinit() From Jason Harris. + + * Microchip PIC32MZ Drivers: + + - PIC32MZ GPIO: Corrects the gpioirq when mismatch mode is + selected. From Abdelatif Guettouche. + + * ARMv7-A: + + - ARMv7-A Build: Fix 'cc1: warning: switch -mcpu=cortex-a7 conflicts + with -march=armv7-a switch' From Xiang Xiao. + + * Nordic NRFxx + + - NRF52: Fix compiler error in nrf52832_errdata.c when following + C89. From Erik Englund. + + * STMicro STM32: + + - STM32 Configuration: It seems one option in the timer configuration + was lost at some point. From Matias N. + - STM32 start-up: Inclusion of nvic.h should not be conditioned on + CONFIG_ARCH_FPU. From Mateusz Szafoni. + - STM32H7 Clocking: Fixes for STM32H7 RCC definitions. From Jukka + Laitinen. + + * STMicro STM32 Drivers: + + - STM32F0/L USART: A few fixes for USART. From Mateusz Szafoni. + - STM32F1/F30 FLASH: RCC register access should not be offset by + FLASH register base. From Matias N. + - STM32F7 CAN: CAN fixes. From Valmantas Paliksa. + - STM32F7 I2C: I2C Interrupt storm fix. I2C track bad state. Now + we track bad state and so the SW reset only when it occurs. From + David Sidrane. + - STM32F7 OTG: Fixes some macros related to OTGFS/OTGHS preventing + OTGHS from working. From Anthony Merlino. + - STM32F7 OTG Device: Correct hard-coded FIFO size that is wrong + for OTG FS. From Ramtin Amin. + - STM32F7 QSPI: Fix QuadSPI interrupts. This commit essentially + replaces wrongly named configuration variable STM32F7_QSPI_INTERRUPTS + into CONFIG_STM32F7_QSPI_INTERRUPTS. Also fixes some getreg/ + putreg where register addresses were used instead of register + offsets From Pierre-Olivier Vauboin. + - STM32H7 I2C: Fix I2C4 compilation for STM32H7. From Jukka + Laitinen. + - STM32H7 UART: Fix compilation for UART7, UART8 and I2C4s. From + Jukka Laitinen. + - STM32L4 USB Device: Add missing PWR USBV enable, correct two USB + register bits From Juha Niskanen. + + * STMicro STM32 Boards: + + - STM32F103-Minimum: USB reset was not working appropriately since + the pin connected to D+ was incorrectly defined and the pullup/down + logic was reversed. From Matias N. + - Nucleo-l476RG: Fix some errors in GPIO logic when debug assertions + are enabled. From Matous Pokorny. + - Nucleo-L476RG: Add missing files of BMP180 example for Nucleo-L476RG. + From Fabian Justi. + - STM32F103-Minimum GPIO: Fix some errors when debug assertions are + enabled. From Matous Pokorny. + - STM32L4 PWM: Fix register addr, en_bit and resetbit for pwm timers. + From Fabian Justi. + - STM32F746G-DISCO: I2C1 config on stm32f746g-disco. Typo in + stm32f7/stm32_i2c.c From Matthew Koch. + + * C Library/Header Files: + + - include/limits.h: Remove the duplicate TMP_MAX definitions. The + standard requires that TMP_MAX defines be in stdio.h. From + Xiang Xiao. + - include/sys/select.h: Fix compiler error when + CONFIG_NSOCKET_DESCRIPTORS is undefined. From Xiang Xiao. + - include/signal.h: Add commented out definition of the si_addr + field. From Joao Matos. + - include/unistd.h: Fixed R_OK/X_OK definitions to match POSIX. + From Joao Matos. + + - libs/libc/locale: Improved error handling in setlocale(). From Joao + Matos. + - libs/libc: Fixed return code in uname(). From Joao Matos. + - libs/libc/stdio: Restore support for printing NULL string as + "(null)". Legacy printf supported printing "(null)" in place for + NULL string: printf("null: %s\n", NULL); => null: (null). This + commit restores this functionality for new printf library. From + Jussi Kivilinna. + + * Examples: apps/examples: + + - apps/examples/pca9635/pca9635_main.c: fix compilation error. From + Mateusz Szafoni. + + * Graphics Utilities: apps/graphics: + + - Various graphics apps (and apps/examples): If CONFIG_VNCSERVER=y, + don't call vnc_default_fbinitialize() directly. That is a violation + of the portable POSIX interface. Instead, call + boardctl(BOARDIOC_VNC_START);. From Gregory Nutt. + - apps/graphics/nxwidgets: CWidgetControl::handleLeftClick now + returns a value to indicate if the click was actually processed or + not. CWidgetControl::pollMouseEvents: Correct return value. From + Gregory Nutt. + - apps/graphics/nxwidgets/: NXWidgets::CNxWidgets: Fix some issues + with returned values. On setting the widget size or position, it was + returning false if there was no change in size or position. Many + places in the code were treating the false return value as an error. + From Gregory Nutt. + + * System Utilities: apps/system: + + - apps/system/nxplayer: Fix some logical errors from recent commits. + They broke the build of the nxplayer as a library vs. a task. + +NuttX-7.31 Release Notes +------------------------ + +The 131st release of NuttX, Version 7.31, was made on July 21, 2019, +and is available for download from the Bitbucket.org website. Note +that release consists of two tarballs: nuttx-7.31.tar.gz and +apps-7.31.tar.gz. These are available from: + + https://bitbucket.org/nuttx/nuttx/downloads + https://bitbucket.org/nuttx/apps/downloads + +Both may be needed (see the top-level nuttx/README.txt file for build +information). + +Additional new features and extended functionality: + + * Core OS: + + - poll(): Removed all references to CONFIG_DISABLE_POLL. The + standard POSIX poll() can no longer be disabled. From Gregory Nutt. + - LWL console: Add support for OpenOCD 'Lightweight Link' protocol + between a target and debugger for use when you need a console but + the target doesn't have a spare serial port or other available + resource. From Dave Marples. + + * Network/Network Drivers: + + - Socket Options: Previous change removed some incorrect SO_LINGER + socket option functionality. SO_LINGER was always enabled if + CONFIG_NET_SOLINGER was selected. This change implements a proper + version of SO_LINGER. It is based on new logic to drain the + buffered TX data, integrated with network event notification system. + Supports notification when UDP or TCP write buffer becomes empty. + From Gregory Nutt. + - Telnet Driver: Handle ctrl events (SIGINT, SIGSTP). From + Valmantas Paliksa. + - Telnet Driver: I/O thread now offloads reading from socket + from client thread to the I/O thread. From Valmantas Palika. + + * Wireless/Wireless Drivers: + + - GS2200M: Add support for Telit GS2200M Wi-Fi module From Masayuki + Ishikawa. + - GS2200M: Introduce CONFIG_WL_GS2200M_SPI_FREQUENCY. Also, changed + usleep(100) to up_udelay(100) to avoid invalid response. From + Masayuki Ishikawa. + - GS2200M: Add channel parameter for AP mode in gs2200m.c From + Masayuki Ishikawa. + + * Graphics/Video/Display Drivers: + + - Video Streaming: Add basic Video Stream and Capture implementation + based on the SPresence SDK code release From Alin Jerpelea. + - video/: Create video/ directory to hold non-driver video-related + logic. From Gregory Nutt. + - EDID: Add some initial EDID logic ported from FreeBSD. From + Gregory Nutt. + - EDID: Add logic to sort video modes by how close they are to the + preferred mode. This is part of the logic to pick the best possible + video mode. From Gregory Nutt. + - EDID/Video Modes: Separate EDID and from videomode management. + They really are separate things.

From Gregory Nutt. + + * Libraries/Header Files: + + - include/cxx/cstddef: Add C11++ std::nullptr_t From junmin-kim. + - libc netdb: Implemented the netdb functions getnameinfo(), + getservbyport(), and getservbyport_r(). From Michael Jung. + + * Documentation + + - Applied a style sheet to static HTML files. Put the TOC of each + document to the side, where it made sense (in some documents the + TOC was actually inside a section so it wasn't possible). In some + cases the TOC is built with a table, in others with a
      element, + so I had to accommodate for this. I also didn't go into collapsing, + although this could really help for some long TOCs. From Matias N. + - Coding Standard: Add a brief section summarizing the major + differences between the NuttX C and C++ coding standards. This is a + stop-gap measure in lieu of having a real C++ coding standard. From + Gregory Nutt. + - Coding Standard: Update requirements for indenting C pre-processor + statements. From Gregory Nutt. + - Coding Standard: Small change discouraging the practice of + enclosing the value argument of 'return' statements in parentheses. + From Gregory Nutt. + - COPYING.

From Gregory Nutt. + - apps/graphics/twm4nx: This change adds a calibration screen to + Twm4Nx. In addition to the Calibration screen port from NxWM, this + required extensions to the event handling logic to support (1) + receiving raw, uncalibrated touchscreen inputs, (2) shutting down + of externally controlled windows. From Gregory Nutt. + - apps/graphics/twm4nx: Move application-related files into different + directories to separate them from the core Twm4Nx files.

From Gregory Nutt. + - apps/graphics/tmw4nx: Add a CClock class that implements the + Twm4Nx digital clock based on the CSLcd simulated SLCD segements. + From Gregory Nutt. + - apps/graphics/twm4nx/README.txt: Add an overview of how to create + Twm4Nx applications. From Gregory Nutt. + + * Industry: apps/industry: + + - apps/industry/abnt_codi: Adds support for ABNT CODI library. This + is an energy meter protocol used in Brazil. From Alan Carvalho de + Assis. + +Bugfixes. Only the most critical bugfixes are listed here (see the +ChangeLog for the complete list of bugfixes and for additional, more +detailed bugfix information): + + * Core OS: + + - Semaphores: Fix a bad assertion in priority inheritance logic. + The comments state correctly that we cannot make any assumptions + about the number of holders of the semaphore, yet the code + asserts if there are any holders. This makes the code behave + closer to what the comments say. From Gregory Nutt. + - Memory Manager: Fix error that occurs when CONFIG_CPP_HAVE_VARARGS + is not defined. In that case, the arguments to the debug macro will + all be evaluated even though they are not used any variables that + are references must at least be defined. From Gregory Nutt. + - System Calls: Adapt the conditional compile logic on when to + include the vfork() syscall proxy and stub to the logic used for + vfork() itself. From Michael Jung. + - System Calls: Fixed SYS_mount syscall define when CONFIG_FS_READABLE + is undefined. From Joao Matos. + - waitpid(): In waitpid, remember to grab the exited child ptr. After + being unblocked in waitpid, the child pointer might be NULL. Modify + to use group_exitchild to get the pointer of recent exited child. + From Yang ChungFan. + + * File System/Block and MTD Drivers: + + - MMC/SD: Fixes bug where thread gets deadlocked due to recursive call + and addresses comment regarding events. When initializing the + MMCSD, if we are being told there is a card, but we fail to + initialize it, we should not re-register for an insertion event as + this will immediately cause us to call in again. Instead, we should + register for a removal event and wait for the card to be removed and + re-inserted. From Anthony Merlino. + + * Networking/Network Drivers: + + - UsrSock: Fix debug logs and remove DEBUGASSERT from + usrsockdev_do_request(). In a client mode, socket() will be the + first request for usrsockdev_do_request(). However, in a server + mode, the first request to accepted sockets will be recv() or other + which depend on applications. So I think we should remove thi + DEBUGASSERT from usrsockdev_do_request(). From Masayuki Ishikawa. + - ICMPV6 Autoconfig: Use ntohs() to convert IPv6 address from + network to host order int network debug output. From Bernd Walter. + - TCP Buffering: Fix TCP buffer send deadlock in iob_copyin() when + IOB buffers are exhausted and network lock is taken. From + Valmantas Paliksa. + - TCP Close: Fix TCP active close in inet_close.c. In previous + implementation, FIN packet was not sent when a socket is actively + closed (e.g. telnetd or webserver) without SO_LINGER. This issue + happens because the socket closing sequence waits for the + status.cl_sem only if lingering timeout is set. However, in many + server use-cases, SO_LINGER is not usually set and even in these + cases, FIN packet must be sent correctly. This changes the logic + in inet_close.c so that it can wait for status.cl_sem regardless + of SO_LINGER. Instead, if SO_LINGERis set, it waits for the + semaphore with timeout option. From Masayuki Ishikawa. + - UDP: Fix C89 compatibility problem. Empty initializers are not + permitted. Caused eZ80 build failure. From Gregory Nutt. + - Telnet: Fix a C89 non-compliance that was breaking the eZ80 build. + From Gregory Nutt. + + * Wireless/Wireless Drivers: + + - NRF24L01: Fix NRF24L01_NCMDS in ioctl.h. The last one in + nrf24l01.h is _WLCIOC(NRF24L01_FIRST + 15) From Masayuki Ishikawa. + - NRF24L01: Fix PIPENO/PKTLEN bitmask in RX FIFO header. In RX FIFO + header, the first byte should use 5 lsb to store PKTLEN and 3 msb + to store PIPENO. However, FIFO_PIPENO_SHIFT was set to 4 which + causes the lsb of pipe number to interfere with the received packet + size stored in the FIFO. This fix RX corruption when using pipe + number > 0. From Federico Braghiroli. + + * Graphics/Display Drivers: + + - Raising Windows: Fix a critical list handling bug in the graphics + system. When a lower-level window was raised while a model window + was in place, then list corruption could occur. From Gregory Nutt. + + * Common Drivers: + + - Serial: Limit the number of times that the poll semaphore is + incremented. From Dave Marples. + - USB Host: Remove duplicate const in USB Host files. From Adam + Porter. + - USB Host Composite: Class-specific descriptors were not available + if the interface is part of a composite device, since only interface + and endpoint descriptors are copied by usbhost_copyinterface(). + This change will copy any class-specific interface descriptors for + use in downstream class drivers. The loop was aborting due to + finding two interface descriptors back-to-back. From Adam Porter. + - USB Host Composite: The cfgdesc pointer was initialized after the + buffer had been advanced, so it was not pointing where it should. + The totallen operations at the end of the function ended up + overwriting memory belonging to the first copied interface + descriptor. From Adam Porter. + - USB MSC: Fix usbmsc_exportluns declaration. Fixes the following + error "...undefined reference to `usbmsc_exportluns'". From Alin + Jerpelea. + + * Architecture Common: + + - Rename all arch//src//chip directories to + arch//src//hardware. This eliminates a name collision + that is usually harmless but does cause problems at the time. The + problem is because the include path includes '.' and 'chip/.', + therefore an inclusion like '#include /src//chip and at arch//src/chip/chip. + From Gregory Nutt. + + * Board Common: + + - Default Configurations: Update configurations for changes to + apps/netutils/netinit configuration. MAC address configuration + was represented by type long long. That is a problem for + architectures that do not support type long long. Replaces by + two long configuration items. From + Gregory Nutt. + - Default Configurations: Change CONFIG_NSH_MACADDR to + CONFIG_NETINIT_MACADDR From Masayuki Ishikawa. + - Default Configurations: Fix mac address settings for RNDIS. + Recently CONFIG_NETINIT_MACADDR_2 and CONFIG_NETINIT_MACADDR_1 were + newly introduced instead of CONFIG_NETINIT_MACADDR. This change + conforms to this change. From Masayuki Ishikawa. + - Default Configurations: Kconfig files should not select + SCHED_WORKQUEUE since that is really only is only the logical OR if + SCHED_LPWORK and SCHED_HPWORK. Selecting it has no effect other + than to produce an erroneous configuration. From Gregory Nutt. + - Linker Scripts: Make sure sections are aligned to 32-bits in all LD + linker scripts. This fixes and issues noted specifically for the + SAMD21 by Bernd Walter, but should be applicable to all other LD + scripts as well. + - Linker Scripts: Add . = ALIGN(4); before every .data section, + add . = ALIGN(4); before every ARM.extab section, add . = ALIGN(4); + before every definition of __exidx_start, add . = ALIGN(4); before + every .init_section. Convert TABs to spaces in all ld linker + scripts. This just makes things easier to modify with scripts + because the files are more consistent. From Gregory Nutt. + - configs/Board.mk: Cannot call $(AR) directly. That works only with + GCC. It must, instead use the ARCHIVE command from Config.mk as do + other Makefiles. From Gregory Nutt. + + * MIPS32: + + - Fix a copy-paste error. On vfork, the GP register was being set to + the new SP value vs. the context GP value. NOTED in Bitbucket issue + 155. From Gregory Nutt. + - An older commit used CP0 register definitions that were not defined + in the NuttX cp0.h header file. Probably these were from the + Microchip hacked up GCC toolchain but are not generally available + outside that toolchain. Fix: Add definitions to NuttX cp0.h header + file. From Gregory Nutt. + + * Microchip PIC32MZ Drivers: + + - PIC32MZ GPIO: Use LAT instead of PORT when writing. From Ouss4. + + * Microchip/Atmal SAM3/SAM4 Drivers: + + - SAMD2/L2: Correct TC register bit field definitions used with + TC_CTRLBCLR and TC_CTRLSET registers. From Bernd Walter. + + * NXP LPC17xx Boards: + + - LPC17xx PROTECTED: On the LPC1769 there are two 16 KiB AHB SRAM + blocks, which are mapped back to back at physical address 0x2007C000 + and 0x20080000 (i.e. right below and right above a 512 KiB boundary). + Memory from those two blocks is considered continuous when assigned + to a heap. In the protected build mode, when the memory protection + unit is used, though, it must be split into two MPU regions. This + is because MPU regions must be naturally aligned, and the 32KiB + continuous address space of the two 16KiB AHB SRAM blocks does not + start at an address divisible by 32KiB. The only other + configurations that use protected build mode on lpc17xx are + currently open1788/knsh and open1788/knxterm. The LPC1788 has the + AHB SRAM blocks mapped more sanely (from an MPU region point of + view), which is probably why no problems emerged here. Both still + compile with my change and other than wasting an MPU region (which + would otherwise remain unused) should work fine. That said, I + have no hardware to confirm. From Michael Jung. + + * NXP LPC54xx Boards: + + - LPCXpresso-LPC54628: Modify the TWM configurations to properly + inject keyboard data. This way, in the case of multiple NxTERMs, + only the NxTerm at the top of the hierarchy gets the keyboard input. + Otherwise, it is not possible to use multiple NxTerms with each the + keyboard input going to a different NxTerm window. From Gregory + Nutt. + + * NXP i.MXRT Drivers: + + - i.MXRT Serial: Fix serial TIOCSINVERT From David Sidrane. + - i.MXRT USDHC: USDHC Stopgap Fix for build breakage From David + Sidrane. + - i.MXRT USDHC: Fix compiler error for CONFIG_IMXRT_USDHC1 && + !CONFIG_IMXRT_USDHC2 From David Sidrane. + + * On Semiconductor LC823450: + + - LC823450-XGEVK: Remove CPU assignment for LPWORK. This change will + reduce audio under-run when running dvfs auto mode. From Masayuki + Ishikawa. + + * SiLabs EFM32 Drivers: + + - EFM32 USB Host: Apply Adam Porter's STM32 fix to EFM32 which has + the same IP. From Gregory Nutt. + + * STMicro STM32: + + - STM32F1 Pinmap: Fix names for complementary PWM outputs From + Mateusz Szafoni. + - STM32L4: If SRAM3 is used as heap, do not power it off in stop 2 + mode. From Juha Niskanen. + + * STMicro STM32 Drivers: + + - STM32 ADC: Fix a compilation error when verbose analog debugging is + enabled for the STM32 ADC. not all STM32s have an SQR4 register. + From rajan gill. + - STM32 PWM: Fix pulse count for the number of counts greater than 128. + From Mateusz Szafoni. + - STM32 USB OTG FS/HS Host: In stm32_ctrlout() in the HS and FS host + drivers, the data buffer isn't sent. This patch passes the buffer + and buflen to the stm32_ctrl_senddata() function. With this change, + I am able to send MBIM control messages to my USB modem, and read the + response. From Adam Porter. + - STM32L4 USB: Fix USB device PMA accesses. USB PMA accesses are + done as 16-bit words on STM32L4 instead of 32-bit words on STM32L1. + From Jussi Kivilinna. + - STM32L4 OTG FS/HS: Fix constant using in comparison to determine + endpoint is interrupt type. From Adam Porter. + - STM32F7 OTG FS/HS: Fix constant using in comparison to determine + endpoint is interrupt type. From Adam Porter. + - STM32H7 PWM: Fix pulse count for the number of counts greater than 128. + From Mateusz Szafoni. + - STM32H7 Serial: Fix error when SINGLEWIRE or + CONFIG_STM32H7_SERIALBRK_BSDCOMPAT defined.

From + David Sidrane. + - STM32H7 USB OTG FS/HS: Fix constant using in comparison to determine + endpoint is interrupt type. From Adam Porter. + - STM32G0 Serial: Fix STM32G0 error when SINGLEWIRE or SERIALBRK_BSDCOMPAT + defined (it reflects previous changes in STM32H7). From Mateusz Szafoni. + + * STMicro STM32 Boards: + + - Nucleo-L432KC: Shorten some long lines, fix i2c pinout.

From Phil Coval. + - STM32F4-Discovery ROMFS: Correct naming of a configuration variable + for ROMFS. From Phil Coval. + - STM32F4-Discovery Build: Fix .ARM.exidx section overlap Source: + https://stackoverflow.com/questions/30778614/arm-none-eabi-ld-section-arm-exidx-overlaps-section-data. + From Alan Carvalho de Assis. + - STM32F4-Discovery PROTECTED: Fix a problem with undefined symbol + 'abort' from GCC library in PROTECTED build. Fix by moving libgcc + into recursive archive group between --start-group and --end-group. + Other kernel/Makefiles suffer from this same issue From Gregory + Nutt. + - Nucleo-H743ZI SPI: Correct typos in function naming. From Jonathan + Richner. + + * TI AM335x: + + - AM335x SYSCLK: Add a function to return a frequency of the system + clock. From Gregory Nutt. + - AM355x CM: Fix a typo in a macro name. From Gregory Nutt. + - AM355x LCD: Fix a few typos. Add things needed by the LCDC driver. + From Gregory Nutt. + + * TI Tiva Drivers: + + - Tiva Ethernet: Add a workaround for tiva with qemu. With qemu, + tiva_ifup() hangs because Ethernet link status can not be set + correctly. This change is a workaround to avoid this issue. From + Masayuki Ishikawa. + + * TI Tiva Boards: + + - TM4C1294-Launchpad: Fix syntax error in oocd.sh script. From + Nathan Hartman. + + * ZiLOG Common: + + - z80: up_addregion() must be prototyped in nuttx/mm/mm.h, not + up_internal.h. Various name changes to better conform to the coding + standard, naming conventions, and use by other architectures. From + Gregory Nutt. + + * ZiLOG Z80 Boards: + + - z80sim: Remove unused function up_earlyserialinit() from serial + driver. From Gregory Nutt. + + * ZiLOG z16f ZNeo: + + - z16f ZNeo: Replicate build changes make for eZ80 and z8 for ZNeo. + From Gregory Nutt. + - ZNeo compile fixes: Fix misuse of FAR which makes a difference on + this platform. Be consistent in use of WDOG_ID type. ZDS-II doesn't + like auto-conversions of struct wdog_s * to WDOG_ID (which is type + struct wdog_s *). From Gregory Nutt. + + * ZiLOG eZ80Acclaim!: + + - eZ80: Fix eZ80 compile problems due to New ZDS-II toolchain and + ongoing bit rot due to non-C89 code creeping into the core OS. From + Gregory Nutt. + - eZ80: Fix some backward conditional logic in Make.defs. From + Gregory Nutt. + - eZ80: Fix a logic error in vector initialization. From Gregory Nutt. + + * C Library/Header Files: + + - signal.h: Fix a C89 compliance problem that cause the eZ80 build to + fail. Empty structure and unions are not accepted by the compiler. + From Gregory Nutt. + - wqueue.h: Allow definitions even if work queues are not enabled. + This solves build failures when work queues are not enabled. From + Gregory Nutt. + - fixedmath.h: Regarding the single precision float to/from fixed + point conversions in fixedmath.h, I believe the floating point + literals should be appended with the letter 'f' to avoid (expensive) + conversions from single to double precision, and thereby also avoid + (expensive if done in SW) double point arithmetic (which is what is + happening upon inspection of my disassembly). From rajan gill. + + - stdio: Fix long long usage in all of the newer printf-related + logic: The selection CONFIG_LIBC_LONG_LONG must be ignored if the + architecture does not support long long types. From Gregory Nutt. + - gm_time_r(): Spurious reorganization of a loop in gm_time_r() to + work around and ZDD-II internal compiler error. Might be a little + bigger now, but is also probably a more structured use of C. From + Gregory Nutt. + - Debug: For platforms whose CPP tool does not support a variable + number arguments to pre-processor macros, we may still need to build + the debug functions even when CONFIG_DEBUG_FEATURES is not selected. + For example, __alert() may be needed if CONFIG_ARCH_STACKDUMP is + set. From Gregory Nutt. + + * Tools: + + - tools/nxstyle.c: Fix error in conditional logic that was preventing + detection bad brace alignment. Add logic to handle alignment of + braces in data initializers which following slightly different + indentation rules. From Gregory Nutt. + - tools/mkexport.sh: The mcu sub-directory chip/ was renamed to + hardware/ in late May of 2019. The mkexport.sh script that copies + these files was not updated, however, until now. Noted by Alin + Jerpelea. From Gregory Nutt. + + * NSH Library: apps/nshlib: + + - apps/nshlib: Fix all places where cle() and readline() are used. + readline() returns EOF on a failure. cle() returns a negated errno + value. Checking only for EOF causes failues to be missed (and + infinite loops ensuing). From Valmantas Paliksa. + - nshlib/nsh_parse.c: Fix a warning about an uninitialized variable + from the ZDS-II compiler. From Gregory Nutt. + - apps/nshlib/nsh_ddcmd.c: Seemingly nonsense change but somehow + works around a compilation error using the ZDS-II toolchain. It + was claiming that vtbl was undefined indd_outfopen(). From Gregory + Nutt. + + * Network Utilities: apps/netutils: + + - apps/netutils/netinit: MAC address configuration was represented + by type long long. That is a problem for architectures that do not + support type long long. Replaces by two long configuration items. + From Gregory Nutt. + - apps/netutils/telnetd/telnetd_daemon.c: Fix a C89 violation that + caused the eZ80 build to fail. From Gregory Nutt. + - apps/netutils/json: Removed. Replaced with apps/netutils/cjson. + From Gregory Nutt. + + * Graphics Utilities: apps/graphics: + + - apps/graphics/twm4nx: Fix an uninitialized variable that was + causing toolbar buttons to randomly come up enabled or disabled. + Remove some unused event definitions. From Gregory Nutt. + - apps/graphics/twm4nx: Fix a calibration screen startup issue. + Make an initial calibration screen optional. From Gregory Nutt. + - apps/graphics/twm4nx: Revise logic to detect clicks on the + background image. The original implementation had some side + effects. From Gregory Nutt. + - apps/graphics/twm4nx: Remove some remaining stuff from TWM that + was never used. Menus need to close after the 'terminal' selection + is made. Otherwise, the menu can become buried under a newly open + menu and not easily recovered. From Gregory Nutt. + - apps/graphics/twm4ndx: Add a 'critical' bit to the eventID. While + resizing, all events will be ignore except those marked critical. + From Gregory Nutt + - apps/graphics/twm4nx: CBackground now brings up the main menu if + the background image is clicked. This makes the behavior the same + across all of the background except when an icon is clicked. From + Gregory Nutt. + - apps/graphics/twm4nx: Fix a bug in placement of icons on the + desktop. When many windows are displayed, a bug in the looping logic + could cause an infinite loop. From Gregory Nutt. + - apps/graphics/twm4nx: Fix some errors found when enabling NX + keyboard support. The most important being that the mouse and + keyboard drivers need to be opened non-blocking. From Gregory Nutt. + +NuttX-8.1 Release Notes +------------------------ + +The 132nd release of NuttX, Version 8.1, was made on September 14, 2019, +and is available for download from the Bitbucket.org website. Note +that release consists of two tarballs: nuttx-8.1.tar.gz and +apps-8.1.tar.gz. These are available from: + + https://bitbucket.org/nuttx/nuttx/downloads + https://bitbucket.org/nuttx/apps/downloads + +Both may be needed (see the top-level nuttx/README.txt file for build +information). + +The major release version number is only incremented when there is a major +change to the OS that makes it more-or-less incompatible with preceding +versions. This release bumps the major version number from 7 to 8 due +primarily to a major reorganization in the what was the configs/ directory +in nuttx-7.31. That directory has been renamed boards/ and now has a +directory structure that mirrors the organization of the arch/ directory +for the most part: + + board/ - Holds all board-related information + board/ - Holds board-related information for all boards that use + the same CPU architecture. For example, all ARM-based boards will be + found under board/arm + board// - Holds board-related information for all boards + that use the same MCU chip family. For example, all STM32-based + boards will be found under board/arm/stm32 + board/// - Holds board-related information for a + specific board. This is analogous to the configs/ directory in + nuttx-7.31. So, for example, the STM32F4-Discovery board support that + was at configs/stm32f4disovery can now be found under + boards/arm/stm32/stm32f4discovery. + boards//// - All configurations for a + specific board can now be found together in this configs/ + subdirectory. So, continuing the example, the STM32F4-Discovery NSH + configuration can now be found at + boards/arm/stm32/stm32f4discovery/configs/nsh. + +In additional, common MCU logic can be found at board///common +and MCU common drivers can be found at board///common. Related +changes include changes to tools/, comments, and documentation that depend +on the board directory structure. + +This re-organization is the work of Alin Jerpelea. Not only did Alin do +this major directory re-organization, but he ran the code standard +compliance tool and corrected every .c and .h file under boards/ so that +they all correctly follow the NuttX coding style. These changes were very +extensive and, hence, will not be addressed individually in the ReleaseNotes. + +You have to give Alin credit for his effort to take on really big jobs and +stick with it until it is finished. Kudos! + +A more constrained re-organization of the drivers/ directory was also +contributed by Augusto Fraga Giachero. Augusto reorganized some driver +directories to make better functional associations and also to make space +for a new set of RF-related drivers. + +Additional new features and extended functionality: +--------------------------------------------------- + + * Core OS: + + - POSIX Message Queues: Add a test to verify that message queue is + closed by the same task group that opened it. If not, then list + corruption would result. This test is only performed if + CONFIG_DEBUG_FEATURES is enabled since it should not normally be an + issue: It would be a strange programming practice to open a + message queue in open task group, then close it in another. From + ???. + - Signal Notifications: Add configuration option to select either the + high-priority or low-priority work queue for SIG_EVTHREA + notifications. From ligd. + - System Calls: In order to support built-in in function in protected + mode, a task_spawn() system call must be supported. task_spawn() + and posix_spawn() are NuttX OS interfaces. In PROTECTED and KERNEL + build modes, then can be reached from applications only via a system + call. Unfortunately this is overly complex because there is a (soft) + limit of 6 parameters in a system call; task_spawn has seven + parameters. This is a soft limit but still difficult to extend + because it involves assembly language changes to numerous + architectures. Better to get more creative. Rather than extend the + maximum number of parameters across all architectures, I opted + instead to marshal the seven parameters into a structure and pass + only a single parameter: A pointer to the structure containing the + seven marshaled parameters. From Gregory Nutt. + - /etc/passwd and /etc/group: Improve the format of the /etc/passwd + file as used in the sim:nsh configuration. It is now a little + more similar to other systems and includes user and group IDs. Add + also an /etc/group file to support future testing. From Gregory + Nutt. + - User/Group IDs: Implement 'real' setuid, getuid, setgid, and getgid + interfaces is so configured (otherwise fall back to stubs that + support only the 'root' user ID and group. Once set, these IDs will + be inherited by all child task groups. From Gregory Nutt. + - Debug Output: Add debug macros for contactless. The various + contactless device drivers currently define device specific debug + macros within their local header files. This patch adds generic + ctls[info|warn|err] macros for the overall contactless subsystem to + be used in future drivers. Ported the existing contactless device + drivers to use these generic logging macros and fixed some logging + bugs along the way. From Michael Jung. + - IOB instrumentation. Introduces producer/consumer id to every IOB + call. This is so that the calls can be instrumented to monitor the + IOB resources and to collect usage statistics. From Anthony + Merlino. + - IOB ProcFS: Adding ProcFS support at /proc/iobinfo to show the data + collected from the IOB instrumentation. From Anthony Merlino. + - Versioning: Report GIT information via ProcFS. GIT info reported: + branch, version, GIT hash, hostname, user, build date. Integrates + into existing .version and ProcFS. From David Alessio. + + * File System/Block and MTD Drivers: + + - BinFS: The BinFS file system uses the same built-in library and + built-in arrays as does NSH. The built-in arrays are simple name- + value pairs that map built-in function names with the user-space + entry point. In the FLAT build, the built-in arrays are available + everywhere via the backdoor left open by the FLAT address space. + In the PROTECTED build, however, the kernel must maintain its own + reference to the user-space built-in array. This commit adds those + kernel globals and a new boardctl(BOARDIOC_BUILTINS) that can be + used by applications to the provide the built-in list reference to + the kernel. From Gregory Nutt. + - MMC/SD: Added support for MMC (eMMC) bigger than 2 GB (Tested with + IMXRT1050EVKB and samsung eMMC 16GB). + - AT24CSxx: Register a character driver for UUID of AT24CSxx chips. + Allows the UUID to read as a file or displayed from an nsh prompt with: + nsh> hexdump /dev/eeprom.uuid From David Alessio. + - Macronix FLASH: Add support for 4-byte addressing on >128Mb + Macronix flash parts From jjlange. + - MX25Rxx: Add support for 512B sectors. From Simon Piriou. + - SST26: Accept the 16MBit Flash when reading the JEDEC-ID at + initialization time. From Ouss4. + + * Network/Network Drivers: + + - IPv4 Options: Now handles reception of IPv4 packets with larger + IPv4 headers containing options. From Gregory Nutt. + - Sockets: Re-order the content of all address-family socket + 'connection' structures so that they begin with a common prologue. + This permits better use of logic for different address family + types. From Gregory Nutt. + - TCP: Make RTO and WAIT_TIME configurable. This fix is not really + correct: TCP RTO really should be calculated dynamically for each + TCP connection: http://sgros.blogspot.com/2012/02/calculating-tcp-rto.html. + From zhangyuan7. + - IP Forwarding: Check if interface is up early on when forwarding to + avoid extra work. As noticed in a previous wireless commit, when + forwarding is enabled and a packet comes in, the packet is attempted + to be sent on each other netdev without regard for whether it is in + the UP state. Of course this is eventually caught, but it can be + caught earlier to avoid unnecessary work, especially in the 6LoWPAN + case where a useless packet conversion will occur. From Anthony + Merlino. + - RNDIS: Expose option to change the number of write requests that + can be in flight. From Anthony Merlino. + - GS2200M: Add UDP support. From Masayuki Ishakawa + - GS2200M: Implement GS2200M_IOC_IFREQ IOCTL command. From Masayuki + Ishikawa. + - GS2200M: Enable NuttX's DHCP client instead of GS2200M's DHCP + client. From Masayuki Ishikawa. + - GS2200M: GS2200M now supports SIOCGIFHWADDR From Masayuki + Ishikawa. + + * Wireless/Wireless Drivers: + + - IEEE802.15.4 Network Driver: Allow 64-bit prefix to be configurable + when auto-configuring the IPv6 address during bring-up. Previously, + only the link-local prefix fe80::/64 was used. Also, put the + network in the DOWN state at the end of initialization. From + Anthony Merlino. + - IEEE 802.15.4 MAC: Adds support for energy detect. Adds support + for energy detect by introducing a new radio call/callback, as the + PHY layer is required to perform the energy detect. From Anthony + Merlino. + - IEEE 802.15.4 MAC: Adds support for getting/setting + macMaxFrameRetries via IOCTL. Add get support for rxonidle + attribute From Anthony Merlino. + - IEEE 802.15.4 MAC: Move the global iobuffer into the macnet struct + so that more than one macnet device can exist. From Anthony + Merlino. + - IEEE 802.15.4 MAC: Defer handling of extracting association + response to LPWORK queue. From Anthony Merlino. + - IEEE 802.15.4 Radios: Support dynamic FCS length. Adds + IEEE802154_ATTR_PHY_FCSLEN. This change introduces + IEEE802154_ATTR_PHY_FCSLEN which the radio layer can support to + set/get the FCS length that's added to the end of the frame. One + use case, in promiscuous mode, is to add back in the FCS of the + received frame by increasing the iob->io_len by the FCS length. + From Anthony Merlino. + - Xbee: Support "WR" AT command for writing parameters to non- + volatile memory. From Anthony Merlino. + - Xbee: Add configuration option for setting the default prefix + to use when bringing up the network and setting the IP address. + From Anthony Merlino. + + * Other Common Device Drivers: + + - RTC: If the RTC time is successfully set, then update the current + system time to match. From ligd. + - ADT7320: Add support for the ADT7320 temperature sensor. From + Augusto Fraga Giachero. + - DAC7554: Add support to the DAC7554 digital-to-analog converter. + From Augusto Fraga Giachero. + - DAT-31R5-SP+: Add support to the DAT-31R5-SP+ digital attenuator. + Creates a the new device driver directory drivers/rf/ to support + drivers related to RF peripherals. It also adds support for the + DAT-31R5-SP+ digital attenuator. From Augusto Fraga Giachero. + - ISL29023: Add basic driver of ISL29023 ambient light sensor. The + basic driver can set operational mode, range, and resolution. It + can also read lux value in continuous mode. Interrupt and the alarm + is not implemented. From Matous Pokorny. + - SHT3x: Add Sensirion SHT3x driver. From Markus Bernet. + + * Simulator: + + - Simulator Build: Even though the simulation has no "chips", it + needs to have CONFIG_ARCH_CHIP and chip sub-directories. Otherwise, + we would have to treat it as a special case in the build system + after the changes to the boards/ directory. From Gregory Nutt. + + * Microchip PIC32MZ: + + - PIC32MZ. Make the PLL input clock configurable. From Ouss4. + + * ARMv7-M + + - Add ARMv7-M setjmp/longjump functions. From David S. Alessio. + + * NXP i.MXRT: + + - i.MXRT Clocking: Enable TRACE clocks if the divider has been + defined in the board's board.h file. From Dave Marples. + + * NXP i.MXRT Drivers: + + - i.MXRT QEncoder: Adds quadrature encoder driver for IMXRT. From + Nicholas Chin. + - i.MXRT uSDHC: This change completes SDIO support for IMXRT, and + also adds support for WiFi using the AP6212A module based on Simon + Piriou's rather excellent work. The patch should also address + DavidS's concern about width setting for USDHC1 and 2. Testing of + the WiFi is minimal so far but functionality is proven. I'm + specifically not happy that the driver doesn't recover elegantly + from a DMA data checksum failure, but that is an issue that can be + dealt with in due course ... I'm trying to get the rest of the + interfaces fleshed out and the hardware proven so it can go for pre- + production build. I _think_ there's only Bluetooth and USB-device + left to implement now. From Dave Marples. + - i.MXRT uSDHC: IMXRT uSDHC driver cmd line reset logic modified. + From Ivan Ucherdzhiev. + + * NXP/Freescale Kinetis Drivers: + + - Kinetis Serial: Add possibility to specify pull-up instead of + open drain for serial single-wire mode. From Beat Kng. + + * NXP LPC17xx/40xx: + + - LPC17xx/40xx Build: Cortex-M system reset is applicable to + LPC17xx/40xx too. From Pavel Pisa. + + * NXP LPC17xx/40xx Drivers: + + - LPC17xx/40xx Ethernet: Follow the procedure listed in the + LPC176x/5x User Manual when reading from and writing to the PHY's + registers (section 10.11.14). I couldn't see any behavioral change + after this commit, but nonetheless is a good practice to follow the + manufacturer's recommended procedure. From Augusto Fraga Giachero. + + * NXP S31K1xx: + + - Added architecture support for the NXP S32K1xx family. Basic + support includes the boot up logic, clock configuration, LPUART + console, Systick timer, GPIO controls, and eDMA (unverified). + + * NXP S31K1xx Drivers: + + - S32K1xx eDMA Leverage eDMA logic from i.MXRT to S32K1XX. Appears + to be the same IP but with fewer channels and features than the + i.MXRT implementation. From Gregory Nutt. + - S32K1xx LPUART: Bring in the LPUART from i.MXRT. It is the same + IP. From Gregory Nutt. + - S32K1xx SysTick: Bring in Cortex-M0+ SysTick and interrupt handling + from samd2l2; bring in Cortex-M4F Systick and interrupt handling + from LPC54xx. From Gregory Nutt. + - S32K1xx GPIO: Bring in GPIO logic from Kinetis. Looks like similar + IP. From Gregory Nutt. + - S32K1xx Ethernet: Unverified port of the i.MXRT Ethernet driver to + the S32K1xx. The i.MXRT uses the same IP. From Gregory Nutt. + - S32K1xx LPSPI and LPI2C: Brings in the LPSPI and LPI2C peripheral + drivers from the i.MXRT which used the identical IP. From Gregory + Nutt. + + * NXP S31K1xx Boards: + + - S32K118EVB. This commit adds initial board support for the NXP + S32K118EVB development board. Currently supports only a minimal + NSH configuration. From Gregory Nutt. + - S32K118EVB: Implement board support for on-board LEDs and buttons. + This is taken from the Freedom-K66f with has the same LED and + button configuration as the S32K116EVB and uses the same GPIO IP. + LEDs, but not buttons, have have been verified. From Gregory Nutt. + - S32K146EVB: Adds initial board support for the S32K146EVB + development board. Currently supports a NSH configuration with a + richer feature set than the minimal configuration of the S32K118EVB. + From Gregory Nutt. + - S32K146EVB: Add support for execution out of SRAM. This is helpful + for bring-up when you want to avoid putting a lethal image in FLASH. + From Gregory Nutt. + - S32K148EVB: Add support for the NXP S32K148EVB development board. + Very similar to the S32K146EVB but with more on-chip memory and + hardware features. + + * Sony CXD56xx + + - CXD56xx: Migrate CXD56xx common code to the common/ directory: + Boot code, FLASH code, I2C driver, UID. From Alin Jerpelea. + - CXD56xx: Add SPH. The SPH is used by the ASMP implementation from + the SDK. From Alin Jerpelea. + + * Sony CXD56xx Drivers: + + - CXD56xx: Add sensors connected to the SCU on Spresense board: + o Avago APDS9930 Proximity and Ambient light Sensor. + o Rohm BH1721FVC Ambient Light Sensor. + o Rohm BH1745NUC Color Sensor. + o Rohm BM1383GLV/BM1383AGLV Pressure Sensor. + o Rohm BM1422GMV/BM1422AGMV Magnetic Sensor. + o Bosch BMI160 Sensor support. + o Bosch BMP280 Barometic Pressure Sensor. + o Kionix KX022/KX122 Acceleration Sensor. + o Murata LT1PA01 Proximity and Ambient light Sensor. + o Rohm RPR0521RS Proximity and Ambient light Sensor. + o BMI160: Add optional I2C address. + From Alin Jerpelea. + - CXD56xx: Add the sensor initialization for CXD56xx boards in the + common board folder: + o APDS9930: typo fix + o cxd56_ak09912 initialization. + o cxd56_bmi160 initialization. + o cxd56_apds9960 initialization. + o cxd56_bh1721fvc initialization. + o cxd56_bh1745nuc initialization. + o cxd56_bm1383glv initialization. + o cxd56_bm1422gmv initialization. + o cxd56_bmi160 initialization. + o cxd56_bmp280 initialization. + o cxd56_kx022 initialization. + o cxd56_lt1pa01 initialization. + o cxd56_rpr0521rs initialization. + o cxd56_sensors initialization. + o Backup Log driver. + o crashlog driver. + o Move gs2200m initialization. + o Move ili9340 initialization. + o Move lpm013m091a initialization. + From Alin Jerpelea. + + * Sony CXD56xx Spresense Board: + + - Spresense: Enable SmartFS and UDP support From Masayuki Ishikawa. + + * STMicro STM32: + + - STM32F4 PLLI2S: Add support to enable the I2S Phase Locked Loop on + STM32F427 and STM32F437 MCUs. From Michael Jung. + + * STMicro STM32 Drivers: + + - STM32 ADC: Add ADC calibration procedure for IP_ADC_V1. Tested on + STM32F100, and it magically increased result accuracy. STM32F103 + has the same calibration procedure. I am not sure about others. + From Matous Pokorny. + - STM32 SPI: TI Synchronous Serial Frame Format.

From + Mateusz Szafoni. + - STM32L4 UART: Serial add HW HS on UART 4 & 5. From David Sidrane. + + * STMicro STM32 Boards: + + - B-L475E-IOT01A: Add mx25rxx memory chip and smartfs support in NSH + configuration. From Simon Piriou. + - LX_CPU: Add support for the PIKRON LX_CPU board. From Pavel Pisa. + - Nucleo-F303RE: Add basic NSH configuration. From Mateusz Szafoni. + - Nucleo-F303RE: Enable console on UART2 and set entry point to + nsh_main() in the PWM configuration. From Mateusz Szafoni. + - Nucleo-H743ZI: Add RTC support. From David Sidrane. + - Nucleo-L432KC: Added GPIO drivers for use with /apps/examples/gpio. + From Daniel P. Carvalho. + - Nucleo-L432KC: Added Zero Cross sensor to nucleo-l432kc. From + Daniel P. Carvalho. + + * TI Tiva: + + - Tiva: Add support for Tiva TM4C123AH6PM. From Nathan Hartman. + - Tiva Configuration: Modify preprocessor logic to support + configurations with no UART. Now similar to logic for other + architectures. From Nathan Hartman. + - Tiva Interrupts: Add handling for IRQs 128 thru 159. From Nathan + Hartman. + + * TI Tiva Drivers: + + - TM4C QEncoder: Reinstate TM4C qencoder driver and expand its + ioctls. Add TIVA_HAVE_QEI0, TIVA_HAVE_QEI1 as applicable to each + ARCH_CHIP_TM4C12*. Rewrite tiva_qe_setup(). Replace tiva_qe_ppr() + with tiva_qe_resetatppr(). Add tiva_qe_resetatmaxpos() and + tiva_qe_resetatindex(). Add missing definitions: + SIGMODE_QUADRATURE, SIGMODE_CLK_AND_DIR, SWAP_NO_SWAP, SWAP_PHA_PHB. + Rename TIVA QEI ioctl QEIOC_PPR to QEIOC_RESETATPPR; add TIVA QEI + ioctl identifiers QEIOC_RESETATMAXPOS, QEIOC_RESETATINDEX. From + Nathan Hartman. + + * TI Tiva Boards: + + - TM4C1294-Launchpad: Enables /dev/userleds in board bring-up for + tm4c1294-launchpad by calling userled_lower_initialize() in + tm4c_bringup(). From Nathan Hartman. + + * TI Tiva Drivers: + + - Tiva GPTM timers: Implement 16-bit PWM mode. Add + tiva_pwm16_sel_event() to choose GPTMCTL.TnEVENT value. Implement + tiva_pwm_mode16(). This also involved numerous corrections to the + 16-bit timer logic. Add tiva_timer16pwm_setperiodduty() to set + initial period, duty cycle, and enable interrupts if requested in + GPTM peripheral. Interrupts are not enabled in NVIC until + tiva_timer16_start() is called. Add tiva_timer16pwm_setduty() to + update duty cycle at any time. Add new TIMER_FLAG_* configuration + flags to enable configuring the 16-bit PWM feature. Extend type of + "flags" in tiva_timer32config_s and tiva_timer16config_s from 8- to + 32-bits to allow more flags. From Nathan Hartman. + + * Build System: + + - Export Build: Export all variables/files to support architecture + independent build against NSH. From Pavel Pisa. + - Application Export: This change too build tools allows to export + built-in applications registry into temporarily created directory + where export archive content is prepared. If the Makefile in apps/ + directory does not define export: target then error is print but + export continues without interruption. It would be more logical to + print warning but there is no way instruct apps make to not print + error. From Pavel Pisa. + - boards/Board.mk: Add support to pass dependency paths. From + Gregory Nutt. + + * Libraries/Header Files: + + - libs/libc/libc.csv: Add some missing C library functions. From + Pavel Pisa. + - libs/libc/libc.csv: Add ioctl() to fs_ioctl() wrapper for varidic + case. From Pavel Pisa. + - libs/libc/builtin/: Moves shared built-in information out of + binfmt/libbuiltin and into libs/libc/builtin where it can be shared + with applications. This should permit built-in application in the + PROTECTED build where binfmt/libbuiltin was not available in user + space. From Gregory Nutt. + - libs/libc/dirent/: Added alphasort() implementation, scandir() + implementation and DT_* definitions to include/dirent.h. Apparently + those definitions are not required by POSIX, but are part of + 4.3BSD and available in glibc as well. From Michael Jung. + - libs/libc/grp/: Added stubbed implementations of getgrgid, + getgrgid_r, getgrnam, getgrnam_r, and initgroups. These functions + are essentially stubs pretending that NuttX supported groups and + that the only configured group in the system was 'root' with gid 0. + The intend is not to provide meaningful new features, but to ease + porting of foreign source code to NuttX. From Michael Jung. + - libs/libc/machine/arm/armv7-m/: Add Cortex M4F machine optimized + fabsf and sqrtf. From David S. Alessio. + - libs/libc/pwd/: Added stubbed implementations. Added stubbed + implementations of getpwuid, getpwuid_r, getpwnam, and getpwnam_r. + These functions are essentially stubs pretending that NuttX + supported users and that the only configured user in the system + was 'root' with uid 0. The intend is not to provide meaningful + new features, but to ease porting of foreign source code to NuttX. + From Michael Jung. + - libs/libc/pwd and libs/libc/grp/: Modify to get user/group data + from /etc/passwd and /etc/group if so configured. From Gregory + Nutt. + - libs/libc/stdio/: Add support for the size_t integer qualifier 'z' + to the printf family. This is kind of tricky due the variety of + sizeof(size_t) on different platforms. From David Sidrane. + - libs/libc/unistd.h: Added stubbed implementations of setuid() and + setgid(). These functions are essentially stubs pretending that + NuttX supported users and groups and that the only configured user + and group in the system were both 'root' with a uid and a gid of 0, + respectively. The intent is not to provide meaningful new features, + but to ease porting of foreign source code to NuttX. From Michael + Jung. + - libs/libc/unistd/: Add getuid() and getgid() stubs to match + MichaelJung's setuid() and setgid(). From Gregory Nutt. + - libc/libc/unistd/: Add stubs for geteuid(), getegid(), seteuid(), + setegid(), setreuid(), and setregid(). NuttX does not currently + support effective user/group IDs, but these stubs will support + linkage of applications that expect these POSIX standard interfaces. + From Gregory Nutt. + + * Symbol Tables: + + - NuttX provides lists of available syscalls and library functions and + tools to process them. The lists can be used to build symbol table + which allows runtime program loading which can reuse functions + already compiled into NuttX system image. List processing, + compilation and linking to the final system image has been possible + only under manual control until now. Provided changes add option + (CONFIG_EXECFUNCS_GENERATE_SYSTEM_SYMTAB) to build complete list of + available functions and syscalls automatically. The symbolic table + is generated in form libsymtab.a which can be reused by application + or directly pull in when "g_symtab" and "g_nsymbols" variables are + requested by EXECFUNCS configuration. I have tried to follow + mechanisms for library compilation in different kernel protection + modes but tested only flat no-MMU build. The basic assumption is + that this library and libraries providing syscall stubs and C- + library functions are available in user-space context and initial + application (usually NSH) registers the symbol table through IOCTL. + The table can be reused then by another applications in their + address space as kernel allows. Simple for flat or protected mode, + I am not sure if really support in MMU mode. It is highly probable + that I have made some mistake, overlooked something, but the + functionality is optional (should not cause troubles in any mode if + disabled) and main purpose is to lower memory overhead when more + applications are loaded on memory constrained system which usually + use direct kernel calling without protection or address space + separation. If the table should be provided by kernel to + applications then makefiles has to be adjusted. From Pavel Pisa. + + * Tools: + + - tools/: Change preferred argument of configurations tools to use + ':' as the delimiter between and . This + is to emphasize that this is not a path; it is configuration + specification. The legacy '/' delimiter is still supported but + not recommend and not advertised. Updated configurations + instructions in README.txt files to show ':' delimiter vs '/' + delimiter. Update all configuration-related tools to accept ':' + separator between board and configuration name. From Gregory Nutt. + + * apps/ General: + + - Makefile: Added support for application-specific export target. + Used by nuttx/tools/mkexport.sh. From Pavel Pisa. + - apps/builtins: Move apps/builtins/builtin_forindex.c to + nuttx/libs/libc/builtin since it is required by kernel logic as + well. Other changes account for movement of builtin.h from + nuttx/include/nuttx/binfmt/built.h to nuttx/include/lib/builtin.h. + From Gregory Nutt. + + * Examples/Tests: apps/examples: + + - apps/examples/uid: Demo used to verify PASSWD and GROUP interfaces. + From Gregory Nutt. + - apps/examples/webserver/: Initialilze network and run forever only + if not built-in app. Infer from CONFIG_NSH_BUILTIN_APPS if we are a + NSH built-in app or not. If built-in app (CONFIG_NSH_BUILTIN_APPS + defined) then we assume network is initialized prior to webserver + starting and we exit on webserver failure. If running standalone + (CONFIG_NSH_BUILTIN_APPS is undefined) then behavior is unchanged: + webserver initializes network and runs forever. From Nathan Hartman. + + * Network Utilities: apps/fsutils: + + - apps/fsutils/passwd: Handle the improved the format of the + /etc/passwd file. It is now a little more similar to other systems. + From Gregory Nutt. + + * Network Utilities: apps/netutils: + + - apps/netutils/dhcpc: Add host name support to DHCP client. From + Masayuki Ishikawa. + + * Network Utilities: apps/wireless + + - apps/wireless/ieee802154/i8sak: I8sak improvements: (1) Adds + support for getting/setting maxretries and promsicuous mode from + i8sak, (2) Fixes a build warning and handles a few cases where a + fault can occur due to not catching missing arguments. From + Anthony Merlino. + - apps/wireless/ieee802154/i8sak: Allow setting the endpoint PAN ID. + From Anthony Merlino. + - apps/wireless/ieee802154/i8sak: Adds support for energy scan result + printout. From Anthony Merlino. + - apps/wireless/ieee802154/i8shark: Adds support for intentionally + suppressing passing the FCS so that Wireshark doesn't try to + validate it. From Anthony Merlino. + - apps/wireless/ieee802154/libmac: Adds support for getting/setting + the FCS length From Anthony Merlino. + - apps/wireless/gs2200m: Add UDP support to the GS2200M driver. From + Masayuki Ishikawa. + - apps/wireless/gs2200m: Add DHCP client handling in ioctl_request(). + From Masayuki Ishikawa. + - apps/wireless/gs2200m: ioctl_request() supports SIOCGIFHWADDR. + From Masayuki Ishikawa. + +Bugfixes: +--------- +Only the most critical bugfixes are listed here (see the ChangeLog for a +more complete list of bugfixes and for additional, more detailed bugfix +information): + + * Core OS: + + - Priority Inheritance: Fix a race in telnet with PRIORITY_INHERITANCE + and SCHED_HPWORK. Sometimes causes an assertion to fire incorrectly. + From David S. Alessio. + - Task Groups: Correct some naming. The NuttX task groups have been + using the acronym 'gid' and also the type 'gid_t' for the the task + group ID. That is incorrect. Than naming is reserved for use with + group permissions. So these were all named to grpid and grpid_t so + that it is clearer that these refer to NuttX task group IDs, and not + to group permissions. From Gregory Nutt. + - Task Termination: nxtask_signalparent() in task_exithook.c may + invalidate the group's parent task ID (tg_ppid) too soon. The + tg_ppid field is use only to remember the parent tasks ID so that it + can send the SIGCHLD signal to it. So it must stay valid until + SIGCHLD has been sent. In nxtask_signalparent(), it calls + nxtask_sigchild() to send SIGCHLD to the parent, then invalidates + tg_ppid. That would be okay, except that the SIGCHLD is only sent + when the last member of the group terminates. That is incorrect; + tg_ppid can be invalidated too soon and, as a consequence, SIGCHLD + would never be sent. Noted by Jeongchan Kim in the Google group: + https://groups.google.com/forum/#!topic/nuttx/SXd8fVwVKBk From + Gregory Nutt. + - sched_get_rr_interval(): sched_get_rr_interval() should return + {0,0} if round-robin scheduling is not selected for the task. From + Gregory Nutt. + - SMP Type Collision: The non-standard, non-portable type cpu_set_t + was created specifically to support the NuttX internal, SMP + implementation. Any resemblance to any other cpu_set_t would be + purely coincidental. However it appears that that coincidence has + occurred. cpu_set_t has an equivalent, non-standard, non-portable + type in the GNU C library. Compilation of libgnat expects this + non-standard type to be defined. Who am I to stand in the way of + progress? This commit removes the conditioning on CONFIG_SMP so + that cpu_set_t is typed (as a uint8_t) even if CONFIG_SMP is not + defined. Reference: Bitbucket issue 164. From Gregory Nutt. + - Binary Loader: Change some debug macros from berr() to binfo() + when dumping module data. The report of problems is important + during development but when it enables complete informative output + about load binaries then the important information can be easily + overlooked. The huge output sent to serial terminal slows loading + significantly as well. From Pavel Pisa. + - Power Management: Fix g_pmcount 16-bits overflow when + CONFIG_PM_XXENTER_COUNT set big value. From ligd. + - Timekeeping: Fix cases in time conversion that must be >= + NSEC_PER_SEC, not > NSEC_PER_SEC. From Gregory Nutt. + + * File System/Block and MTD Drivers: + + - opendir(): opendir() set errno to a negative value in one error + case. From Michael Jung. + - SmartFS: Update smartfs smart_scan() function. From Simon Piriou. + - ProcFS: Add missing LF to cpuload procfs output From David Alessio. + - MMC/SD: Copy/paste error fix in the SDIO-based block driver for + MMC. From Ivan Ucherdzhiev. + - MMC/SD: Correct a misplaced #endif in the SDIO-based driver. From + Gregory Nutt. + + * Networking/Network Drivers: + + - Ethernet Configuration: Ethernet packet buffer size cannot be + permitted to go below 1294 if IPv6 is selected. From Gregory Nutt. + - TCP RST: Fix outgoing RST packet with wrong ack number. From + biantao. + - TCP Close: Fix TCP close flow; free the connection after all TCP + close process finished. From zhangyuan7. + - UDP Broadcast: Remove net stack dependency from CONFIG_NET_BROADCAST. + This change allows us to use CONFIG_NET_BROADCAST without network + stack (i.e. usrsock application can use broadcast) From Masayuki + Ishikawa. + - UDP: Fixes a UDP send copy-paste error in the new SO_LINGER code: + CONFIG_TCP_NOTIFIER to CONFIG_UDP_NOTIFIER. From Juha Niskanen. + - TCP and UDP: Fix errors in the new implementation of SO_LINGER. + The tcp_drain() and udp_drain() functions were casting the working + argument to the wrong type, resulting in hangs and abnormal + behavior. There is a complexity in the TCP drain logic when the + remote peer closes the socket before all Tx data has been flushed. + Sometimes we are not notified of this case and wait the entire + timeout unnecessarily. There is a workaround in place in + tcp_txdrain(), but this really should be revisited. From Gregory + Nutt. + - 6LoWPAN: Removes unnecessary conversions that were happening due to + a misunderstanding of byte ordering with EUI-64. From Anthony + Merlino. + - RNDIS: Fix issue with DEBUGASSERT when using composite device and + endpoint numbers not being the default. From Anthony Merlino. + + * Wireless/Wireless Drivers: + + - wireless network devices: Attach radio to d_buf before registering + device to handle forwarding case. When CONFIG_NET_IPFORWARD is + enabled, and CONFIG_NET_6LOWPAN is being used, a packet that + attempts to get forwarded on the 6LoWPAN interface will require + that the radio's buffer be attached to d_buf. Otherwise an assertion + will fire. The underlying "radio" in this case is the + mac802154_netdev. This behavior has probably not been observed + because the buffer is normally attached in the periodic txpoll + worker. However, in my case, the 6LoWPAN interface was not UP yet, + and therefore the worker hadn't run yet. From Anthony Merlino. + - IEEE 802.15.4 MAC: Fixes issues with extended address. 1) Extended + address should be read-only. 2) Extended address should be placed + in frame in "reverse-canonical" order. The extended address is a + read-only attribute and thus an attempt to write the extended + address should be denied. Instead, the extended address should + really be either set by the PHY/radio itself, or provided at board + bring-up time to the radio layer. The MAC layer now pulls in the + extended address from the radio any time the MAC is reset. The + extended address is also supposed to be sent in the frame in + reverse-canonical order. This is very confusing in the standard and + it wasn't until I realized it was backwards in Wireshark that I + researched this further. Searching online I find documents from the + committee for suggestions/feedback on the future standard. It isn't + in the 2015 standard but a newer version of the standard will + presumably clarify this. It says that the extended address should be + written in reverse-canonical form, meaning the OUI comes last, not + first inside the frame. From Anthony Merlino. + - IEEE 802.15.4 MAC: Frame Version should have been 1, but was being + set to 3 when payload exceeds version 0 capabilities. Adds warning + to build to indicate what is noted in the menu for + CONFIG_MAC802154_NTXDESC From Anthony Merlino. + - IEEE 802.15.4 MAC: Fixes issue where the txdesc's ackreq flag was + not being set, despite the frame containing a Frame Control field + with ACKREQ bit set. From Anthony Merlino. + - Xbee: Fix logic to prevent deadlock scenario when there are no + available IOBs From Anthony Merlino (2018-12-21). + - Xbee: Change assumption about destination address mode for incoming + frames. If a short address has been assigned to our radio, then + assume we were addressed using that. Otherwise we were addressed + using our extended address. From Anthony Merlino. + - Xbee: Initialize the short address to the unspecified address and + query for the extended address on initialization. From Anthony + Merlino. + - Xbee: Adds CONFIG_XBEE_LOCKUP_WORKAROUND option and corresponding + logic to workaround an issue where the XBee locks up and stops + responding. This typically happens when there is a lot of data + being received over the link. When the XBee stops responding, many + times, querying the XBee kicks it out of this state. However, + occasionally the XBee is completely locked up and the XBee has to + be reset. This change handles these conditions by periodically + (if not naturally occurring) querying the XBee. If during any + query, the XBee does not respond within a certain number of + attempts, the XBee is reset. From Anthony Merlino. + - Xbee: Cancel query timeout upon receiving the expected response. + Add protection for race condition that can cause association + timeout to continue firing repeatedly From Anthony Merlino. + - Xbee: Detect lockup and reset XBee in xbee_req_data From Anthony + Merlino. + - Xbee: Fixes one instance of the use of IOBUSER_WIRELESS_MAC802154 + which isn't available without the software MAC layer. Instead we + use IOBUSER_WIRELESS_RAD802154 throughout the whole driver since it + is always available when IEEE 802.15.4 support is enable. From + Anthony Merlino. + + * Common Drivers: + + - pipes: Use inode reference counter instead of device reference + counter to handle dup(). I found that if I dup() a pipe, the + reference counter d_refs is not increased. If I close any of the + fd, backed by the same pipe, the pipe will be freed. This causes + any further usage on the fd referencing a non existent pipe. This + change uses the inode reference counter, which is properly + maintained during dup(). From Yang ChungFan. + - SPI Bitbang: Fix build error when the SPI bitbang variable width + support is enabled. From Augusto Fraga Giachero. + - GPIO Lower Half: Remove limitation when pintype > + GPIO_INTERRUPT_PIN. From ligd. + + * ARMv4/ARMv5 + + - Classic ARM7/ARM9: When performing stability test, the application + would cause kernel crash. When I trace the stack, I find that + register R1 has been changed, and its value is the same as register + CPSR. In up_fullcontextrestore.S, the restoration of R0 and R1 is + not atomic: 'msr cpsr r1 will enable interrupts and the recovery of + r0 and r1 may be interrupted and the value or R1 may be changed. + Fix is to use a single ldmia to restore R0, R1, and return via R15. + From Loyen Wang. + + * ARMv7-A + + - ARMv7-A: Fix typo and missing quotation for ARMv7-A. From Oki + Minabe. + - ARMv7-A: Fix double increment in armv7-a's + arm_addrenv_destroy_region(). From Oki Minabe. + - ARMv7-A: Fix L2 page table mask for ARMv7-A page allocator. From + Oki Minabe. + + * ARMv7-M + + - Interrupts. Removes the architecture-common + CONFIG_ARCH_INT_DISABLEALL configuration option (but which was + supported only by ARMv7-M). In the normal course of things, + interrupts must occasionally be disabled using the up_irq_save() + inline function to prevent contention in use of resources that may + be shared between interrupt level and non-interrupt level logic. + Now the question arises, if we are using BASEPRI to disable + interrupts and have high priority interrupts enabled + (CONFIG_ARCH_HIPRI_INTERRUPT=y), do we disable all interrupts except + SVCall (we cannot disable SVCall interrupts). Or do we only disable + the "normal" interrupts? If we are using the BASEPRI register to + disable interrupts, then the answer is that we must disable ONLY the + "normal interrupts". That is because we cannot disable SVCALL + interrupts and we cannot permit SVCAll interrupts running at a + higher priority than the high priority interrupts (otherwise, they + will introduce jitter in the high priority interrupt response time.) + Hence, if you need to disable the high priority interrupt, you will + have to disable the interrupt either at the peripheral that + generates the interrupt or at the NVIC. Disabling global interrupts + via the BASEPRI register cannot effect high priority interrupts. + From Gregory Nutt. + - ARMv7-M Priorities: In the 'normal' case, the priority of the + SVCALL interrupt was the same as the priority of the high priority + interrupt. This means that SVCALL interrupt processing can defer + the high priority interrupt and result in the jitter in that + interrupt response. Fix is to raise the priority of the high + priority interrupt above the priority of the SVCALL interrupt. + Suggested by Nathan Hartman. From Gregory Nutt. + + * Microchip i.MXRT Drivers: + + - i.MXRT ENC: Fix some errors in register bit definitions. Noted by + Arie de Muijnck. From Gregory Nutt. + - i.MXRT LPI2C: Slave addresses are now correctly shifted when + sending START. TX/RX FIFOs now discarded on error to prevent FIFO + underflow errors. Fixes error checking to use priv structure and + removes checking of BBF flag as it is not an error. From Nicholas + Chin. + + * Microchip PIC32MZ Drivers: + + - PIC32MZ SPI: Fix SPI Mode selection.

From Bernd + Walter. + + * NXP LPC17xx/40xx Drivers: + + - LPC17xx/40xx ADC: Only use PCLKSEL0 for ADC on LPC176x family. + From jjlange. + - LPC17xx/40xx Ethernet: Set speed back to 10Mbps if 10Mmbps link + negotiated. From Augusto Fraga Giachero. + - LPC17xx/40xx I2C: Abort I2C transfers if a timeout has occurred. + If a timeout has occurred in the middle of a I2C transfer, the next + I2C interrupt should abort any transfers and send a stop condition + to the corresponding I2C bus. Failure to do so will result in + memory corruption / undefined behavior as priv->msgs points to a + region of memory it doesn't owns anymore after lpc17_40_i2c_start + returns. From Augusto Fraga Giachero. + - LPC17xx/40xx I2C: Calculate the appropriate timeout for I2C + transfers. Depending on the bus frequency and transfer size, I2C + transactions can take quite a bit, so a fixed timeout is not a + good solution. Calculating the timeout at run time poses some + overhead but still better than aborting long transactions. From + Augusto Fraga Giachero. + + * NXP/Freescale Kinetis Drivers: + + - Kinetis I2C: i2c transfer ensure correct result returned. + kinetis_i2c_transfer released the mutex then fetched the state, + this resulted in returning the correct results. From David + Sidrane. + + * NXP LPC17xx/40xx Drivers: + + - LPC17xx/40xx CAN: If BOARD_CCLKSEL_DIVIDER is not equal to 1 on + LPC178x or LPC40xx then base clock rate is calculated incorrectly + because CCLK frequency does not correspond to PLL0 clock which is + used for PCLK. This is partially workaround solution. It would + be probably better to define BOARD_PCLK_FREQUENCY even for LPC176x + targets and use that to replace divisor by base_clock in up_dev_s. + From Pavel Pisa. + + * NXP LPC17xx/40xx Boards: + + - LPC17xx/40xx Ethernet: Add missing LPC17_40_PHY_CEMENT_DISABLE + variable to the lpc17xx/40xx Kconfig file. For some reason this + setting was not referenced anywhere except in the Ethernet driver. + From Augusto Fraga Giachero. + - LPC17xx/40xx Ethernet: Fix the initialization for DP83848x PHYs. + The DP83848x requires the RMII mode to be manually enabled through + the MII_DP83848C_RBR register.

From Anthony Merlino. + - STM32 OTGH[FS|HS] Host STM32 host only initiates transfer if + buflenl > 0. From Adam Porter. + - STM32F7/H7/L4 OTG host: Adam Porter's fix for STM32 FS/HS probably + should be applied to STM32 F7, H7, and L4 OTG host which are very + similar. From Gregory Nutt. + - STM32/F7/H7/L4: This change was required to get my devices + (CDC-MBIM) to enumerate. Initially the system timed out retrieving + the USB configuration descriptor. Ctrl IN requests got nothing but + NAKs. I found that the initial SETUP packet and corresponding IN + transfer were fine; it was the Status OUT phase that was getting the + NAK. After receiving a NAK on the Status OUT, the code would loop + back and issue another ctrl IN, which will always fail because the + data was already transferred before. Thus the entire transfer would + 'timeout'. The fix I implemented moves the DATANAK timeout loop to + only apply to the Status OUT. Both the ctrl IN and the Status OUT + need their own retry loops. From Adam Porter. + - STM32F7 SDMMC: If there is only one SDMMC it is slot 0 From David + Sidrane. + - STM32F7 USART1: USART1_RXDMA is dependent on STM32F7_DMA2 not + STM32F7_DMA1 From Anthony Merlino. + - STM32H7 DBGMCU: Memory Map DBGMCU is @ 0x5c001000 From David + Sidrane. + - STM32F7 SDMMC: Fix warning when DMA is not enabled. From David + Sidrane. + - STM32H7 Ethernet: Fix some errors in Ethernet MAC configuration. + From Markus Bernet. + - STM32H7 Ethernet: Correct stm32h7 mac address filtering. Correct + the MAC address 0 register definition and remove the 'receive all' + flag. Now the Ethernet driver only receives packets addressed to + correct MAC. From Jukka Laitinen. + - STM32H7 Ethernet: Correct memory corruption error. The Ethernet + driver initialization incorrectly wrote to DMACRXCR instead of + DMACSR when trying to clear the stopped flags. This caused + invalid buffer length in the DMACRXCR, causing DMA to overflow the + RX buffers when large packets are sent to the device.

From David Sidrane. + - STM32H7 Serial: Serial fix undefined with TERMIOS From David + Sidrane. + - STM32H7 UARTs: Fix UART7/8 typos. Fix bug in ETH_MACQTXFCR + configuration. From Markus Bernet. + + * STMicro STM32 Boards: + + - Multiple STM32 Boards: If CONFIG_SCHED_CRITMONITOR is selected, + then make sure that ITM and DWT resources are enabled before + accessing ITM and DWT registers.

Carvalho. + + * TI Tiva: + + - Tiva Configuration: Rename TM4C123GH6PMI identifiers to + TM4C123GH6PM. Rationale: In terms of firmware programming, there + is no functional difference between these parts: TM4C123GH6PMI7, + TM4C123GH6PMI7R, TM4C123GH6PMT7, and TM4C123GH6PMT7R. From a + programming standpoint, all of the above parts are TM4C123GH6PM, + which means it doesn't make sense to differentiate between PM and + PMI. (The PM means 64-LQFP. The I means temperature range -40C to + +85C. It could be T meaning -40C to +105C. The R means it ships in + Tape and Reel packaging as opposed to Tray.) From Nathan Hartman. + - Tiva Configuration: Rename TM4C1294NC identifiers to TM4C1294NCPDT. + Rationale: TM4C1294NC is ambiguous: TM4C1294NCPDT is a 128-TQFP, + TM4C1294NCZAD is a 212-NFBGA. The TM4C1294NC part currently + supported by NuttX is the TM4C1294NCPDT used on the TI EK-TM4C1294XL + "Connected LaunchPad" (see configs/tm4c1294-launchpad). To ensure + the correct part is fully specified, this commit updates all + TM4C1294NC identifiers to TM4C1294NCPDT. From Nathan Hartman. + - Tiva Configuration: Fix TM4C129XNCZAD part number in Kconfig and + identifiers. Rationale: Fully specify that this is the 212-pin BGA + package (ZAD ending) and for consistency with earlier changes to + other Tiva TM4C12x part numbers in Kconfig names and identifiers. + From Nathan Hartman. + + * TI Tiva Drivers: + + - Tiva TM4C 1-Wire: Fix wrong description on define TIVA_1WIRE_BASE: + Was "EEPROM and Key Locker" (same as the item above). Now "1-Wire + Master Module." Make DMACTL symbols visible for TM4C123: Remove + "#ifdef CONFIG_ARCH_CHIP_TM4C129" guard around UART DMA Control + (DMACTL) symbols. These bits are valid on TM4C123 devices, as well + as on TM4C129. Also, improve the comment on UART_DMACTL_DMAERR. + From Nathan Hartman. + - Tiva GPIO Interrupts: LM3S, LM4F, TM4C: Fix GPIO IRQ error, ports + R, S, T. Preprocessor logic for CONFIG_TIVA_GPIOx_IRQS was setting/ + clearing port Q defines when it should act on ports R, S, T. + gpioport2irq() was missing handling for port T. From Nathan + Hartman. + - Tiva Timers: Fix minor errors in tiva_timerlib.c. Fix incorrect + preprocessor conditionals related to Kconfig defines: + CONFIG_TIVA_TIMER32_EDGECOUNT -> CONFIG_TIVA_TIMER16_EDGECOUNT, + CONFIG_TIVA_TIMER32_TIMECAP -> CONFIG_TIVA_TIMER16_TIMECAP, + CONFIG_TIVA_TIMER32_PWM -> CONFIG_TIVA_TIMER16_PWM. From Nathan + Hartman. + - Tiva Timers: Fix errors in low-level timer support. + tiva_gptm_configure() and tiva_gptm_release() were calling + tiva_emac_periphrdy() instead of tiva_gptm_periphrdy(). Fix + error in "abcde" description of bit flag defines. From Nathan + Hartman. + - Tiva Timers: Fix one code error and some comment errors. + tiva_timer16_setinterval(): Was DEBUGASSERTing on mode != + TIMER16_MODE. Fixed to DEBUGASSERT on mode == TIMER16_MODE. + From Nathan Hartman. + + * ZiLOG Z80 Boards: + + - z80sim Serial: Fix uart_dev_t initializer: pollfds[] is a array of + pointers and, hence, the NULL initializer must be included in braces. + Noted by Paul Osmialowski in Issue #160. From Gregory Nutt. + - z80sim Interrupts: Missed a name change up_irqinitialize to + z80_irq_initialize. From Gregory Nutt. + + * C Library/Header Files: + + - include/netinet/in.h: Rename __pad member to sin_zero in struct + sockaddr_in. Libwebsockets initializes the 'sin_zero' member of + sockaddr_in objects to zeros. Apparently, judging from mailing list + entries, there are platforms on which not doing this causes + undefined behavior. On NuttX compiling respective code is broken, + as the corresponding member variable is called '__pad'. Neither in + the 'nuttx' nor in the 'apps' repository did I find any reference to + this identifier. Thus, I believe its a safe bet to just rename it. + UNIX Network Programming states in this regard: "The POSIX + specification requires only three members in the structure: + sin_family, sin_addr, and sin_port. It is acceptable for a POSIX- + compliant implementation to define additional structure members, and + this is normal for an Internet socket address structure. Almost all + implementations add the sin_zero member so that all socket address + structures are at least 16 bytes in size." From Michael Jung. + + - libs/libc/libc.csv: Correct dependency of setlocale on + CONFIG_LIBC_LOCALE. From Pavel Pisa. + - libs/libc/machine/arm/armv7-m: Fix build error for ELF. From + Masayuki Ishikawa. + - libs/libc/math.csv: Correct format of some function entries. From + Pavel Pisa. + + * Tools: + + - tools/: Change all occurrences of /bin/(ba)sh in shell scripts to + /usr/bin/env bash which appears more portable From Manuel Sthn. + + * NSH Library: apps/nshlib: + + - apps/nshlib/: As noted by David S. Alessio, 'cat' should not output + any additional newline at the end of the cat'ed file content. This + additional newline was added to assure that the NSH prompt was + presented on a new line. However, that is not the correct behavior + of 'cat' per the IEEE std: "The standard output shall contain the + sequence of bytes read from the input files. Nothing else shall be + written to the standard output." Reference: + https://pubs.opengroup.org/onlinepubs/009695399/utilities/cat.html. + This commit changes the function nsh_catfile() which underlies the + 'cat' command and well as other NSH commands. Although this is the + correct behavior for 'cat' it may not be the correct behavior for + other commands implemented via nsh_catfile(). That remains to be + determined. From Gregory Nutt. + + * System Utilities: apps/system: + + - apps/system/cle/: ASCII DEL should be treated by Delete-Left. From + Dave Marples. + - apps/system/i2ctool: (1) Friendlier I2C "knock-knock" uses only + read request. While many I2C slave devices have multiple indexed + registers, some have only one register and it's not indexed. For + example, the I2C bus switch TCA9548A has only a Control Register, + attempting to index to "Reg[0]" alters its contents to 0x00 + disabling all subordinate buses. This patch fixes that problem by + simply trying to read something/anything from the slave. This also + helps coax out slaves with register files that start from a higher + index, i.e. the AT24CS0x, FLASH chips with a UUID that appears as a + 2nd I2C slave at (address+8), report their serial number at + Reg[80]-Reg[8F] and will NAK a read of Reg[0]. (2) Modify get/set + to prevent write of reg index if not specifed From David Alessio. + + * Network Utilities: apps/netutils: + + - apps/netutils/dhcpd: Fixes bug where hwaddr was being used instead + of ipaddr in the ARP update. This bug seems to have been introduced + three years ago during a rewrite to remove a direct OS call to arp. + I'm not sure how others have not run into issues with this. The + behavior I was observing was that the DHCPD would go to offer an IP + address, but then send a ARP request for the IP instead because it + didn't know where to send the data. From Anthony Merlino. + - apps/netutils/netinit/: Remove warnings. Unhook PHY notification + signal handler when cleaning up, if an error occurs after the signal + handler is put into place. From Nathan Hartman. + + * Wireless Utilities: apps/wireless: + + - apps/wireless/ieee802154/i8sak: Fixes conversion from extended + address to IPv6 address. From Anthony Merlino. + +NuttX-8.2 Release Notes +------------------------ + +The 133nd release of NuttX, Version 8.3, was made on November 16, 2019, +and is available for download from the Bitbucket.org website. Note +that release consists of two tarballs: nuttx-8.2.tar.gz and +apps-8.2.tar.gz. These are available from: + + https://bitbucket.org/nuttx/nuttx/downloads + https://bitbucket.org/nuttx/apps/downloads + +Both may be needed (see the top-level nuttx/README.txt file for build +information). + +Additional new features and extended functionality: +--------------------------------------------------- + + * Core OS: + + - Signals: Add support for SIGPIPE default action. SIGPIPE uses + SIG_SIGPIPE_ACTION which terminates process by default. It also + could be ignored. From liuhaitao. + - Spinlocks: Remove support for re-entrant spinlocks. They seemed + like a good idea, but they are never used. From Xiang Xiao. + - Memory Manager: Remove the assumption that one character equals + eight bits. From Xiang Xiao. + - Power Management: Historically, the NuttX PM subsystem has + consisted of two functional components: (1) an "Upper" part that + detects state changes based on a random walk driven by activity + levels, and (2) and "lower" part that implementst the state changes. + This change decouples that upper activity-based logic from the lower + random walk logic and allows use of other upper state detection + logic (such as a custom, application-specific state machine). From + Matias Nitsche. + - boardctl(): Expose power manager function through boardctl() + interface. From Xiang Xiao. + + * File System/Block and MTD Drivers: + + - GD25: Add support for a new FLASH vendor. From zhangbo_a. + - GD25: Add support for GD25 device with 256-Mbit capacity. From + YanLin Zhu. + - GD25: Add 4-byte address operation for capacity larger than + 128-Mbit. From YanLin Zhu. + - GD25: Add gd25_lock/unlock to case: enable 4-bytes address From + ligd. + - GD5F: Add gigadevice SPI NAND FLASH driver. From YanLin Zhu. + + * Networking/Network Drivers: + + - Networking: Use ntoh() when printing IPv6 addresses so that the + addresses appear in friendlier host order vs. network order. From + Bernd Walter. + - Netlink: Implement minimal NETLINK_ROUTE socket functionality that + can (for now) be use used to obtain a list of network devices, IPv4 + ARP and IPv6 Neighbor tables, and IPv4 and IPv6 routing tables. + From Gregory Nutt. + + * Wireless/Wireless Drivers: + + - BCM43438A1 Bluetooth: Add support for the BCM43438A1 Bluetooth + capability. From Dave Marples. + - HCIUART Shim: Add a serial 'shim' to allow any regular serial port + to support a Bluetooth H4 interface and to be used to drive a + Bluetooth device. From Dave Marples. + - BCM4343x HCIUART: BCM4343x HCIUART support. From Dave Marples. + - BCM43xxx: Move drivers/wireless/ieee80211/ to + drivers/wireless/ieee80211/bcm43xxx/ since the directory only + contains only BCM43362 and BCM43438 related code. From Xiang Xiao. + - GS2200M: Add reset handler to interface. Add reset and un-reset + sequence in driver. From Masayuki Ishikawa. + + * Audio/Audio Drivers: + + - Audio: Add message type to support audio trigger. From anchao. + + * Other Common Device Drivers: + + - Altair: Add support for the altair LTE modem driver. From Alin + Jerpelea. + - MCP2515: MCP2525 SPI STD-EXT ID fixes. From DisruptiveNL. + - OpenAMP: Brings in the drivers needed to support OpenAMP. These + changes were ported from https://github.com/FishsemiCode/nuttx. + This port was effort of a number of people, I rather arbitrarily + gave authorship to Guiding Li because he has the largest number of + fundamental quashed commits from the Xiamoi repository. From + Guiding Li. + + * Simulator: + + - Simulator: Add stack coloration feature. From ligd. + - Simulator: Report PM activity on simulated UART. From Matias + Nitsche. + - Simulator: Add host ftruncate() support. From chao.an. + - Simulator: Replace all CONFIG_DEV_CONSOLE with USE_DEVCONSOLE for + arch/sim and compile up_devconsole.c conditionally. From Xiang + Xiao. + - Simulator OpenAMP: Support OpenAMP between two simulator + instances. Please read rpserver/rpproxy section in + boards/sim/sim/sim/README.txt for more information. From chao.an. + + * ARMv7-M + + - ARMv7-M: Add BPIALL register address. From Dave Marples. + - ARMv7-M MPU: Add user peripheral helper + + * Atmel SAMD2/L2 Boards: + + - Arduino-M0: Add initial board support for the Arduino M0 which is + based on the SAMD21 chip. Include nsh and usbnsh configurations. + From Alan Carvalho de Assis. + + * NXP i.MXRT Drivers: + + - i.MXRT LCD: Add support for LCD. Clean up some LCD-related + interfaces. From Fabio Balzano. + - i.MXRT Serial: This change improves the performance of UART serial + ports on the IMXRT by enabling the RX & TX FIFOS and transmission on + the holding register being empty (TDRE) rather than transmission + being complete (TC). From Dave Marples. + - i.MXRT Pin Mux: This change separates out the pinmux and iomux + functions cleanly. For ease of conversion default IOMUX definitions + have been added into imxrt_iomux.h. The change effectively does two + things: (1) unifies the iomux definitions - previously some pins + had them, and some didn't. This effectively made it impossible to + use the pinmuxes without editing the header file in the standard + distribution tree. And (2) unifies the pin definitions so that every + pin now has a suffix. This makes it *much* easier to see when a pin + is in use in your code, because it will always have a definition in + your board.h file. From Dave Marples. + - IMXRT1020-EVK: Add support for the MIMXRT1021-EVK board. It + features nsh, netnsh and usdhc sample configurations. From Dave + Marples. + + * NXP i.MXRT Boards: + + - IMXRT1060-EVK: Add basic LCD support for the board IMXRT1060-EVK. + From Fabio Balzano. + - IMXRT1060-EVK: Added Littlevgl demo configuration into the + IMXRT1060-EVK board directory. From Fabio Balzano. + + * NXP/Freescale Kinetis Drivers: + + - Kinetis Ethernet: Add support for TJA1100 PHY. From David Sidrane. + + * NXP S31K1xx: + + - S32K1xx: Support configuration and initialization of the flash + configuration bytes. From Gregory + + * NXP S31K1xx Boards: + + - S32K1**EVB: Create a special FLASH section to hold the FLASH + configuration bytes. From Gregory Nutt. + - S32K146EVB: Added configuration script and instructions for using + Thread-Aware OpenOCD for the S32K146 with Eclipse. From Han + Raaijmakers. + + * Renesas RX65N: + + - RX65N: Adds a port of to the Renesas RX65N Micro-controller. This + port includes Serial (UART) driver (13 ports) and Ethernet + driver. From Anjana. + + * Renesas RX65N Boards: + + - RSK RX65N-2MB: Add support for the RSK RX65N-2MB board. From + Anjana. + - GR-Rose: Add support for the GR-Rose board. From Anjana. + + * Sony CXD56xx + + - CXD56xx CPU FIFO: Add configurations for CPU FIFO elements. From + Alin Jerpelea. + - CXD56xx Loader: Update loader and gnssfw ver. 17660. From Alin + Jerpelea. + - CXD56xx SMP: Add support for SMP. To run cxd56xx in SMP mode, new + boot loader which will be released later must be used. From + Masayuki Ishikawa. + - CXD56xx SMP: Add IRQ routing for SMP in cxd56_irq.c. In CXD56xx, + each external interrupt controller can be accessed from a local + APP_DSP (Cortex-M4F) only. This change supports IRQ routing for SMP + by calling up_send_irqreq() in both up_enable_irq() and + up_disable_irq(). From Masayuki Ishikawa. + + * Sony CXD56xx Drivers: + + - CXD56xx I2C: Add ability to set the i2c frequency to other than just + 100 or 400 Hz. From Alin Jerpelea. + - CXD56xx SDHCI: Reduce power consumption by stopping SD clock. Re- + enable SD clock during access to SD card. Improve GNSS low + sensitivity with SD card inserted. From Alin Jerpelea. + + * Sony CXD56xx Spresense Board: + + - CXD56xx Board Common: Add the Altair LTE modem support on the + Spresense board. From Alin Jerpelea. + - CXD56xx Board Common: Add Spresense Image Processor. Enable support + for accelerated format converter, rotation and so on. using the CXD5602 + image processing accelerator. + - Spresense: Add board specific pin configurations of CXD5602 pins to + fit Spresense board. From Takayoshi Koizumi. + - Spresense: Add a configuration option to select if an extension + board is attached to the SPresence. If there is no extension board + attached, the SPresense may run in a low-power mode by default (as + determined by the CONFIG_CXD56_CUSTOM_PINCONFIG option). If an + extension board is present, then the SPresense will need to run at a + higher power mode, selected by the new CONFIG_SPRESENSE_EXTENSION + option. From Gregory Nutt. + - Spresense Camera: Add ISX012 camera initialization and + configuration. From Alin Jerpelea. + - Spresense OS test: Enable ostest in rndis/defconfig and + wifi/defconfig. From Masayuki Ishikawa. + - Spresense: Add --gc-sections to LDFLAGS and add -ffunction-sections + and -fdata-sections to ARCHCFLAGS in scripts/Make.defs. From + Masayuki Ishikawa. + - Spresense SMP: Add smp configuration. From Masayuki Ishikawa. + - Spresense SCU: The SCU has to be initialized at bootup on Spresense + board because several functions depend on it. Add audio control + definitions. Add configuration for the audio implementation. From + Alin Jerpelea. + - Spresense: Add audio and board audio control implementation. From + Alin Jerpelea. + - Spresense: Sdd power_control and audio_tone_generator. Add a simple + way to control the audio buzzer with defined frequency for user-space + apps. From Alin Jerpelea. + - Spresense: Add the optional initialization of GNSS and GEOFENCE at + boot if the drivers are enabled From Alin Jerpelea. + - Spresense: Add LTE configuration. From Alin Jerpelea. + - Spresense: Enable high current mode for the Spresense Extension + board on all examples that have SDCARD support. From Alin Jerpelea. + - Spresense: Add lcd examples configuration. This is a configuration + for the basic nx examples From Alin Jerpelea. + + * STMicro STM32: + + - STM32F0/L0/G0: Add support for STM32G070xx family. From Daniel + Pereira Volpato. + - STM32F0/L0/G0 Power: Scale dynamic voltage and flash wait states + properly on STM32G0 chips. Included preliminary implementation of + PWR module VOS support. From Daniel Pereira Volpato. + - STM32L4R5ZI: Add support for the STM32L4R5ZI chip type. From Jussi + Kivilinna. + - STM32 L4+ DMA: Add DMA support for STM32L4+ series. From Jussi + Kivilinna. + - STM32 L4 Clocking: Enable "Range 1 boost" mode if any PLL freq + above 80 Mhz. From Jussi Kivilinna. + - STM32 L4 LPTIM: Add support for LPTIM timers on the STM32L4 as PWM + outputs. From Matias N. + - STM32 H7 Progmem: Add FLASH progmem support. From David Sidrane. + + * STMicro STM32 Drivers: + + - STM32 Serial: Single Wire add pull{up|down|none} via new IOCTL + command. From David Sidrane. + - STM32 F0/L0/G0 Serial: Single Wire add pull{up|down|none} via + new IOCTL command. From David Sidrane. + - STM32 F0/L0/G0 PWM: Add PWM support. From Daniel Pereira Volpato. + - STM32 G0 TIM: Support timers available on STM32G070. Includes TIM1 + PIOs, TIM driver lower-half. From Daniel Pereira Volpato. + - STM32 F7 Serial: Single Wire add pull{up|down|none} via new IOCTL + command. From David Sidrane. + - STM32 H7 BBSRAM: Exclude BBSRAM from cacheable when + CONFIG_ARMV7M_DCACHE. ST placed the STM32H7 BBSRAM in the SRAM + default memory region which is cacheable. This change sets the + BBSRAM memory range to non-cacheable. From David Sidrane. + - STM32 H7 SDMMC: Add SDMMC support and IDMA as well as interrupt + driven transmission. Support pull-ups and SDIO. From David Sidrane. + - STM32 H7 Serial: Single Wire add pull{up|down|none} via new IOCTL + command. From David Sidrane. + - STM32 L4 OTGFS: Enable OTGFS for STM32L4+ series. The OTGFS + peripheral on stm32l4x6 and stm32l4rxxx reference manual is exactly + the same. From Jussi Kivilinna. + - STM32L4 IDLE Loop: (1) Added BEGIN_IDLE()/END_IDLE() to stop call + so that we also get notification via LED of the STOP mode, (2) Added + the stm32l4_clockenable call as previously discussed, and (3) Added + call to pm_changestate() to inform drivers we're back to running + after the call to stm32l4_stop() returns. From Matias N. + - STM32 L4 Serial: Single Wire add pull{up|down|none} via new IOCTL + command. From David Sidrane. + + * STMicro STM32 Boards: + + - Nucleo-G070RB: Initial support for board STM32 NUCLEO-G070RB, + including NSH config. Enables PWR peripheral and set SYSCLK to + maximum frequency. From Daniel Pereira Volpato. + - Nucleo-G070RB: Enable basic timers. Add TIMx clock frequencies to + board.h. From Daniel Pereira Volpato. + - Nucleo-G070RB: Add PWM support and GPIO_TIM3_* mappings. Add a PWM + configuration. From Daniel Pereira Volpato. + - Nucleo-G070RB: Add button driver support, Add driver support. Add + GPIO configuration. From Daniel Pereira Volpato. + - Nucleo-L476RG: Add required definitions if libcxx is enabled. From + Matias N. + - Nucleo-L476RG: Add support for LPTIM timers as PWM outputs. From + Matias N. + - Nucleo-H743ZI: Added GPIO device driver for user-space apps. From + Heiko Demlang. + - olimex-stm32-e407: Newer Olimex E407 boards are populated with + STM32407ZE chips. From David Alessio. + - STM32F4-Discovery: Add support for external DS1307 module. From + Alan Carvalho de Assis. + - STM32F4-Discovery: Add support for MMCSD_SPI. This change works + with STM32F4 Discovery Shield plus microSD click From Masayuki + Ishikawa. + - STM32F4-Discovery: Add support for gs2200m. Works with mikroe + STM32F4 Discovery Shield (slot3) From Masayuki Ishikawa. + + * TI Tiva: + + - TM4C129ENCPDT: Add support for Tiva TM4C129ENCPDT. From Nathan + Hartman. + + * TI Tiva Boards: + + - TM4C123G-Launchpad: SPI CAN functionality on TM4C123GXL. From + DisruptiveNL. + + * Build System: + + - tools/Config.mk: Eliminate use of the built-in implicit rules. + From anchao. + - tools/Config.mk and Makefile.unix: Support the incremental build + for configuration change. From Xiang Xiao. + - tools/Config.mk: Support the ability to change the CFLAGS for + the compilation of a single file. Set special compiler options as + follows the rule: sourcefile + fixed suffix "_[A|C|CPP|CXX]FLAGS". + For example in apps/examples/hello/Makefile: + $(SRCDIR)/hello_main.c_CFLAGS = -DTEST. From Xiang Xiao. + - Configuration: Auto-select CONFIG_BUILD_LOADABLE when either + CONFIG_BUILD_KERNEL or CONFIG_BINFMT_LOADABLE is selected. From + Xiang Xiao. + + * Libraries/Header Files: + + - libs/libc: Add CONFIG_MODLIB_SYSTEM_SYMTAB to generate the symbol + table for dlopen/insmod. From Xiang Xiao. + - getdelim() and getline(): Add implementations of the POSIX + functions getdelim() and getline(). Because of how the function is + defined, getline() canot be used on platforms that use CR-LF lin + terminations. From Gregory Nutt. + - alarm(), setitimer(), and getitimer(): Implement alarm(), + setitimer() and getitimer() APIs. From liuhaitao. + + * Tools: + + - tools/mkexport.sh: Copy the essential build script files too and + move Make.defs/gnu-elf.ld into scripts like board folder layout. + From Xiang Xiao. + - tools/mkexport.sh: Should export full content for FLAT build even + with CONFIG_BUILD_LOADABLE. From Xiang Xiao. + - tools/testbuild.sh: Add an option to select the number of CPUs to + use with 'make' From Gregory Nutt. + - tools/indent.sh: Add a command line option to suppress reformatting + of comments. This is useful when comments are already correct + and/or contain formatted data such as tables or lists. From Gregory + Nutt. + - tools/nxstyle.c: Add detection of carriage returns. Improve + reporting of TABs. From Gregory Nutt. + - tools/nxstyle.c: Add logic to detect if there is a blank line + following the final right brace. From Gregory Nutt. + - tools/nxstyle.c: Eliminate false alarm errors on comments that are + to the right of code when the comment terminator is on the same + line as the last of the comment. From Gregory Nutt. + - tools/nxstyle.c: Eliminate false alarms when checking for + alignment of comments to the right of code. Fix check for C++ style + comments so that strings like http:// and https:// do not generate + false alarms. From Gregory Nutt. + - tools/nxstyle.c: Eliminate false positive 'Invalid character after + asterisk in comment block'. From Gregory Nutt. + + * apps/ Build System: + + - apps/ Build System: Numerous changes for improvements and general + clean-up of the apps/ build system. Too many small and individual + changes to list here. Includes many improvements related to loadable + modules and symbol table generation, removal of duplicated logic, + renaming of binary directories, use of cygpath, etc. From Xiang Xiao. + - apps/Application.mk: Support the ability to change the CFLAGS for + the compilation of a single file. Set special compiler options as + follows the rule: sourcefile + fixed suffix "_[A|C|CPP|CXX]FLAGS" + As an example in apps/examples/hello/Makefile: + $(SRCDIR)/hello_main.c_CFLAGS = -DTEST + From Xiang Xiao. + - apps/Application.mk and main.c files: Change builtin's entry point + from main to xxx_main by macro expansion. This change make the + entry point fully compliant with POSIX/ANSI standard. From Xiang + Xiao. + + * Examples/Tests: apps/examples: + + - apps/examples/audio_rttl: Add a simple RTTL player demo that is + able to play tunes according to an RTTL song. From Alin Jerpelea. + - apps/examples/bmi160: Add bmi160 example app. This app will read + the BM160 data and list it on the NSH console. From Alin Jerpelea. + - apps/examples/charger: Simple charger example that will display on + the console voltage and current values. From Alin Jerpelea. + - apps/examples/netlink_route: Add test/example of NETLINK_ROUTE + 'get' operations. From Gregory Nutt. + + * NuttShell: apps/nshlib: + + - apps/nshlib/: Add rptun cmd for boot remote core. From ligd. + - apps.nshlib/: Add a -t option to the arp command which will enable + printing the entire ARP table. From Gregory Nutt. + - apps/nshlib/: Add new NSH command, 'pmconfig'. From ligd. + + * System Utilities: apps/system: + + - apps/system/cle: Add basic color support to the CLE editor. + From Dave Marples. + - apps/system/i2c: While many I2C slave devices have multiple + indexed registers, some have only one register and it's not indexed. + For example, the I2C bus switch TCA9548A has only a Control + Register, attempting to index to "Reg[0]" alters its contents to + 0x00 disabling all subordinate buses. This change fixes that + problem by simply trying to read something/anything from the slave. + This also helps coax out slaves with register files that start from + a higher index, i.e. the AT24CS0x, FLASH chips with a UUID that + appears as a 2nd I2C slave at (address+8), report their serial + number at Reg[80]-Reg[8F] and will NAK a read of Reg[0]. Modified + get/set to prevent write of reg index if not specified. + - apps/system/i2c: Added a 'dump' command to issue a single + transaction to retrieve multiple bytes from an I2C slave and + register/offset. From David Alessio. + - apps/system/spi: Add options to specify devtype, id for chip + select. From David S. Alessio. + - apps/system/symtab: Remove system/symtab since the same + functionality exist in nuttx now. From Gregory Nutt. + - apps/system/usrsock_rpmsg: Add rpmsg based usrsock implementation. + From Jianli Dong. + + * Network Utilities: apps/netutils: + + - apps/netutils/cjson/: Update default version to 1.7.12. Previous + releases raise compilation warnings about redefined true/false. + From raiden00pl. + - apps/netutils/netlib/: Add a function to read the entire ARP table + using NETLINK_ROUTE protocol. From Gregory Nutt. + - apps/netutils/netlib/: Add support for retrieving a snapshot of the + IPv6 neighbor table using Netlink sockets. From Gregory Nutt. + - apps/netutils/netlib/: Add a utility function that will return a + list of all network devices in the UP state. From Gregory Nutt. + - apps/netutils/netlib/: Add function to retrieve routing tables + using Netlink. From Gregory Nutt. + +Bugfixes: +--------- +Only the most critical bugfixes are listed here (see the ChangeLog for a +more complete list of bugfixes and for additional, more detailed bugfix +information): + + * Core OS: + + - Signals: Fix undefined reference from sig_default.c to + sched_suspend() if CONFIG_SIG_SIGSTOP_ACTION is not defined. From + raiden00pl. + - waitpid(): Fix a NULL pointer dereference on race without + DEBUG_ASSERT. From David Alessio. + - WD Timers: Back out a kludge-workaround in wd_start for an SDCC + compiler problem fix back in Feb 2017. That workaround now appears + to conflict with newer GCC versions using (unsupported) warning + options and SDCC no longer needs the work-around. From Gregory + Nutt. + - clock_systimespec(): Fix early timespec overflow if using 32 bit + system timer. From Jens Grf. + - Spinlocks: spin_trylock handle memory barrier and instrumentation + correctly. From Xiang Xiao. + - Power Management: Fix a problem where a timer cannot start when it + encounters a very small pmtick. From ligd. + - boardctl(BOARDIOC_MKRD): This change corrects a problem with NSH: + NSH was calling the OS internal function ramdisk_register() in + violation of the portable POSIX interface. This change solves the + problem by introducing a new boardctl() function BOARDIOC_MKRD + which moves the RAM disk creation into the OS. From Gregory Nutt. + - boardctl(BOARDIOC_ROMDISK): Add support for the new + BOARDIOC_ROMDISK command. This allows applications to create ROMFS + block drivers without illegal direct calls to romdisk_register. + + * File System/Block and MTD Drivers: + + - SmartFS: Fix O_CREAT without O_TRUNC truncating existing file. + Also nothing in POSIX says that O_APPEND should prevent O_TRUNC. + From Juha Niskanen. + - SmartFS: Honor O_APPEND on writes. Also document pwrite() bug/ + limitation. From Juha Niskanen. + - GD25: spi_devid argument was not used in initialization. GD25 + driver was always using priv->spi_devid initialized to zero by + kmm_zalloc(). This change initializes it from the supplied function + argument. From Juha Niskanen. + - MMC/SD: Set wrbusy after success of all the operations. Any + failure could leave wrbusy set when it should not be if the + operation failed. From David Sidrane. + - MMC/SD: Enter a removed card state On a failure. If we fail to + read cardstatus in mmcsd_transferready consider this a hard error + and set the card to removed. From David Sidrane. + - MMC/SD (SDIO): Align DMA buffer for MBURST size. From David S. + Alessio. + + * Networking/Network Drivers: + + - Socket close(): Fixed problems noted by Bernd Walter: Eliminate an + incomplete test when a disconnection event happens. When a + disconnection event occurs, the close logic MUST always terminate + the wait. The conditional test was not incorrect, however, it + lacked 'else' logic and would simply ignore that disconnection event + in some cases. That is bad because there may not be another + disconnection event and that can lead to hangs (or at least very, + very long delays). From Gregory Nutt. + - ICMPv6: Dispatch ICMP_POLL to device's callback list too since + icmpv6_neighbor stills append the callback into this list. From + Gregory Nutt. + - ICMPv6: Decouple autoconfig and ICMPv6 socket to avoid an invalid + Kconfig combination. From Xiang Xiao. + - ICMPv6: cmpv6_autoconfig() error handling must not overwrite + overwrite the error code. From Xiang Xiao. + - TCP/UDP: Fix a chicken and egg problem by eliminating the check of + the arp/neighbor tables before packet transmission: + 1. For buffered TCP/UDP case, if CONFIG_NET_ARP_SEND / + CONFIG_NET_ARP_IPIN / CONFIG_NET_ICMPv6_NEIGHBOR isn't enabled + and the table doesn't contain the Ethernet address for the + destination IP address yet, then the logic will skip the real + transmission and then ARP/neighbor logic can't steal the final + buffer to generate the ARP/ICMPV6 packet. + 2. For all other case, the TCP layer or user program should already + contain the retransmit logic, the check is redundant and may + generate many duplicated packets if ARP/ICMPV6 response is too + slow because the cursor stop forward. If user is still concerned + about the very first packet lost, he could fix the issue by + enabling CONFIG_NET_ARP_SEND / CONFIG_NET_ICMPv6_NEIGHBOR. + From Xiang Xiao. + - UDP sendto(): Add a check for the device that is polling. In the + multiple network device case, this check is necessary to prevent + sending the UDP packet to the wrong device. From Gregory Nutt. + + * Wireless/Wireless Drivers: + + - MRF24J40: Correct erroneous isolation of address mode field and + subsequent bad comparison. From Gregory Nutt. + - GS2200M: Add SPI_SELECT() to _read/write_data() in gs2200m.c + - BCM43xx Wireless: In the SDIO interface, the behavior of the DMA + setup differs, depending on the hardware capability + SDIO_CAPS_DMABEFOREWRITE. If this capability is set, then the DMA + setup much be done before the transfer setup. Dave Marples + modified this file for the i.MXRT USDHC which does have the + SDIO_CAPS_DMABEFOREWRITE. Xiao Xiang reports that this change + breaks the Wifi on the Photon which does not report the + SDIO_CAPS_DMABEFOREWRITE and suggests reverting the change. In + reality both changes are correct but must be conditioned on the + DMA capability of the underlying SDIO device. From Gregory Nutt. + + * Common Drivers: + + - Various drivers (Cloned logic): On error, memory was freed, but + the error was not returned. It just continued as though no error + happened. From Petro Karashchenko. + - Serial: Fix data corruption when outputting data in SMP mode From + Masayuki Ishikawa. + - Serial: serial_io.c used signal numbers, but did not include + signal.h. This has no problems but missing signal definitions have + been seen in certain cases. From David Sidrane. + - Serial DMA: Avoid uart_xmitchars_done() move the tail bigger then + head. If ioctl(TCOFLUSH) occurs between uart_xmitchars_dma() and + uart_xmitchars_done(), TCOFLUSH will reset xmit buffer, then + uart_xmitchars_done() will move the 'tail' ahead of 'head', then + sends lots of wrong data. From ligd. + - mkfifo(): mkfifo() should return -1 and set errno on failure From + raiden00pl. + - RAMLog: Fix ramlog readers never awakened up when using ramlog as + syslog or console. We also make an attempt to avoid the thundering + herd problem if there are multiple readers/pollers. This change also + removes forcing CONFIG_RAMLOG_CRLF in nuttx/syslog/ramlog.h as there + is no point of wasting precious RAM for useless characters. From + Juha Niskanen. + - USB CDC/ACM: Fix memory leak of RX failsafe timer. From Juha + Niskanen. + - USB HID Keyboard device: Fix keyboard debounce algorithm used when + CONFIG_HIDKBD_NODEBOUNCE is undefined. From Jeff Theusch. + - USB HID Keyboard: Change default for CONFIG_HIDKBD_POLLUSEC per + recommendation of Jeff Theusch. From Gregory Nutt. + - VL53L1X IOCTLs: IOCTL commands for the VL53L1X did not follow the + sequence. Noted by Daniel Pereira de Carvalho. From Gregory Nutt. + - syslog: syslog_force does not set errno so do not test against it. + From Juha Niskanen. + - syslog: Fix assertion that assumes re-opened syslog file is the + same. Logic in syslog_file_channel() is calling syslog_initialize() + for the default syslog device as a recovery action after failed + syslog_dev_initialize(). From Juha Niskanen. + + * Simulator: + + - Simulator HostFS: Skip '.' and '..' in readdir' From Xiang Xiao. + - Simulator HostFS: Fix warning: 'mapflags' may be used uninitialized + in this function. From Xiang Xiao. + - Simulator Tickless: Correct the calculation of the Tickless timer + period. Fix some missing initialization of globals and missing + return values. From Matias N. + - Simulator: Add -m32 to HOSTLDFLAGS if enable CONFIG_SIM_M32. From + Xiang Xiao. + - Simulator PM: Fixes compilation for sim target when enabling power + management. From Matias N. + - Simulator Build: Fixes missing recursion into sim board directory + for dependency generation. From Matias N. + - Simulator SIMUART: Remove CONFIG_SIM_UART_DATAPOST for arch/sim. + It's very dangerous to call NuttX API from simuart_thread. From + Xiang Xiao. + + * ARMv7-A + + - ARMv7-A: Apply Masayuki Ishakawa's change for ARMv7-M to this SMP + architecture as well. From Gregory Nutt. + + * ARMv7-M + + - ARMv7-M: Fix a deadlock in up_sigdeliver() in SMP mode. In + previous implementation, up_disable_irq() was called before + recovering local context. However, I noticed a deadlock happens in + the following situation. For example, if up_sigdevliver() is in + progress on CPU0 and CPU1 has called up_cpu_paused to CPU0, hence + g_cpu_irqlock has been locked by CPU1, in this case, we would see a + deadlock in later call of enter_critical_section() to restore + irqcount. To avoid this situation, we need to call + enter_critical_section() to break the deadlock. From Masayuki + Ishikawa. + + * Atmel SAM3/4 Boards: + + - SAM4CM: Fix cpustart() implementation. In Cortex-M, offset 0 in + vector table stores initial stack pointer and offset 4 stores reset + vector. From Masayuki Ishikawa. + + * Atmel SAMA5Dx Boards: + + - SAMA5D4-EK: Fix bad conditional compilation for + board_app_initialize(). Should depend only on CONFIG_LIB_BOARDCTL, + CONFIG_BUILD_KERNEL is irrelevant. From Gregory Nutt. + + * Microchip i.MXRT: + + - i.MXRT WFI: WFI needs to be disabled on i.MXRT. We found the + reason: The imxrt1050 is configured to use SYSTICK for the kernel + timer, but SYSTICK cannot wake up the MCU from low-power modes. + Disable low-power modes on this MCU until we have support for an + alternative timer. Earlier versions of the board (EVK, not EVKB), + had A0 silicon which by default did not enter low-power mode on a + WFI. With this change in place together with the previous one my + system is stable, just using more power than it should. From Dave + Marples. + + * Microchip i.MXRT Drivers: + + - i.MXRT Serial: TC (Transmission complete) and TDRE (TX Buffer + Empty) were transposed in imxrt_serial.c. The end result was that + for unoptimized code everything worked fine, but optimized code got + itself into a real mess and continually fired interrupts. From Dave + Marples. + + * Microchip i.MXRT Boards: + + - IMXRT1020-EVK: Make naming of the LED consistent. In most places + it is referred to as LED1. In board.h it is referred to as + USERLED1. The i.MXRT1020-EVK hardware user guide (HUG) uses the + name USERLED. This command makes all names internally consistent + and consistent with the HUG. Noted by Alin Jerpelea. From Gregory + Nutt. + + * NXP/Freescale Kinetis Boards: + + - TWR-K60N512: Suppress errors related to card detect GPIO + configuration if SDHC support is not enabled. From Gregory Nutt. + + * NXP LPC17xx/40xx Drivers: + + - lpc17xx/40xx I2C: Respect the I2C_M_NOSTART flag. Sending a + restart condition when not requested will break other drivers that + depend on this behavior. From Augusto Fraga Giachero. + - LPC17xx/40xx Ethernet: Use usleep() instead of up_delay() for large + wait times. From Augusto Fraga Giachero. + + * NXP LPC54xx: + + - LPC54 Clocking: Fix PLL settings. For the lpc54628 Rev. E board + the PLL was not configured properly and the board would not boot + correctly. I checked the startup files from the official IDE and + inspected the assembly instructions for the libraries used. From + Andrei Stefanescu. + + * NXP i.MXRT Boards: + + - IMXRT1060-EVK: Fix FT5X06 CTRSTn pin configuration, increased + number of pollwaiters for the FT5X06, tuned resolution during + pointer dragging. From Fabio Balzano. + + * On Semiconductor Boards: + + - LC823450: Fix cpustart() implementation. In Cortex-M, offset 0 in + vector table stores initial stack pointer and offset 4 stores reset + vector. From Masayuki Ishikawa. + - LC823450-XGEVK: Fix build error for posix_spawn. From Masayuki + Ishikawa. + + * Sony CXD56xx: + + - CXD56xx Assertions: Replace some assertions with error return + values. From Alin Jerpelea. + - CXD56xx Interrupts: Fix hang-up when error interrupt occurs. From + Alin Jerpelea. + - CXD56xx Pin Configuration: PIN_AP_CLK is used as a port selector of + SDIO expander on the extension board, and is set output low in + initialization. Therefore, this pin cannot be used by the other + board. To avoid this restriction, remove this initial operation + because this pin is pulled down by default on the extension board. + From Alin Jerpelea. + - CXD56xx: Remove duplicate NVIC_SYSH redefinitions. The NVIC_SYSH + is already defined in nvicpri.h From Alin Jerpelea. + + * Sony CXD56xx Drivers: + + - CXD56xx SDHCI: Fix initial value of semaphore in sdhci driver. + From Alin Jerpelea. + + * Sony CXD56xx Boards: + + - Spresense: The SD Card TXS02612 port expander is hosted on the + Extension board and should not be enabled if the extension board is + not present. From Alin Jerpelea. + + * STMicro STM32: + + - STM32 F4 Pin Multiplex: Ethernet pin ETH_RMII_REF_CLK is an input. + From Gregory Nutt. + - STM32 H7 ADC: Fix typos in ADC register definitions. From Markus + Bernet. + - STM32 H7: Heap allocation, SRAM and SRAM1 are not continuous From + David Sidrane. + - STM32 H7 CRC: Add the CRC option in KConfig. From Eduard Niesner. + - STM32 H7 RCC: Add PLL3 Support and only enable PLLs if used. From + David Sidrane. + - STM32 L4x6xx RCC: This fix is needed if HSI clock is selected. + Otherwise when waking up from STOP mode, the MSI clock is selected + instead of the HSI clock. From Matias N. + + * STMicro STM32 Drivers: + + - STM32 USB Host: There was no relationship between + CONFIG_STM32_USBHOST and CONFIG_USBHOST, yet they they were used + interchangeably. This means that can (and did) get out of synch + causing link time failures. This change adds logic to select + CONFIG_USBHOST when CONFIG_STM32_USBHOST is selected, keeping the + two settings synchronized. Furthermore, since CONFIG_STM32_USBHOST + is the authoritative setting, all occurrences of CONFIG_USBHOST were + replaced with CONFIG_STM32_USBHOST. From Gregory Nutt. + - STM32 SDIO: SDIO Fix system hang on card eject. From David Sidrane. + - STM32 F7 Ethernet: Large Ethernet packet can leads network halt. + From Bazooka Joe. + - STM32F7 OTGHOST: OTGFS_EPTYPE_INTR should be OTG_EPTYPE_INTR. From + Gregory Nutt. + - STM32 F7 SDMMC: SDMMC Fix system hang on card eject. From David + Sidrane. + - STM32 L4 Firewall: Correct a test to determine if an address lies + in FLASH or not. Improper mask caused test to always fail. From + Gregory Nutt. + - STM32 H7 Ethernet: Bazooka Joe's fix to the STM32 F7 Ethernet + driver should be applied to the H7 as well. The other STM32 + Ethernet drivers already have the change. From Gregory Nutt. + - STM32 H7 Ethernet: Fix ETH_MACMDIOAR_CR_MASK bit mask. From Markus + Bernet. + - STM32 H7 SDMMC: SDMMC Fix system hang on card eject. From Gregory + Nutt. + - STM32 H7 FLASH: Flash driver BUG fixes. From David Sidrane. + - STM32 H7 TIM: Correct register bit definitions and alternate + functions. Fix other copy-paste definitions. From Daniel Pereira + Volpato. + - STM32 L4 SDMMC: SDMMC Fix system hang on card eject. From David + Sidrane. + + * STMicro STM32 Boards: + + - STM32F4-Discovery: Fix build error for posix_spawn. From Masayuki + Ishikawa. + + * TI Tiva: + + - TIVA IRQs: Fix wrong IRQ vector number. From Nathan Hartman. + - Tiva FLASH: Fix several mistakes in tiva_write(). (1) Fix wrong + use of && when & was intended. (2) Add compile- time warning + directive because according to this function's interface, it is + supposed to support unaligned writes and/or writes of arbitrary + numbers of bytes to FLASH. However, this function does NOT support + that at this time. This needs to be fixed. (3) Fix wrong + preprocessor conditional. Was written to use the 32-word write + buffer only for TM4C1294NCPDT. This buffer is available on all + M4C123 and TM4C129 parts. Now conditioned upon + CONFIG_ARCH_CHIP_TM4C123 or CONFIG_ARCH_CHIP_TM4C129. (4) Add + comments to document the intent of the above preprocessor logic. + From Nathan Hartman. + + * Xtensa + + - Xtensa: Apply Masayuki Ishakawa's change for ARMv7-M to this SMP + architecture as well. From Gregory Nutt. + + * Build System: + + - Makefiles: Change ${shell pwd} to $(CURDIR) since pwd doesn't exist + on Windows From Xiang Xiao. + - tools/Makefile.unix: Fix build error when issue 'make -B': "mkdir: + cannot create directory 'staging': File exists: + tools/Makefile.unix:269: recipe for target 'staging' failed". From + Xiang Xiao. + - All ARM linker scripts: Preface all _ebss definitions with '. = + ALIGN(4)'. Otherwise, the following .bss section may not be aligned + properly. From Gregory Nutt. + - MIPS Linker Scripts: The PIC32M* start-up code initializes .bss by + writing 16 bytes at a time in a loop. The start (_sbss) alignment + is only required to be 4 bytes since the write is done with 4 store + instructions. From Gregory Nutt. + - Top-level Kconfig: Add some protection so that you cannot select an + architecture-specific header file if the architecture does not + provide the header file. From Gregory Nutt. + - libc Kconfig: Should select the NuttX float.h file automatically + if the NuttX math library is selected. From Gregory Nutt. + - tools/Makefile.unix: Make COMMON_DIR work with + CONFIG_ARCH_BOARD_CUSTOM. From Xiang Xiao. + - tools/ Make fragments: Fix the various minor issue for NUTTXLIBS / + USERLIBS: (1) Remove libcxx duplication in FlatLibs.mk and from + kernel space, (2) Remove libpass1 from KernelLibs.mk since kernel + build doesn't support the two pass mode, and (3) Remove FSDIR + related comment since file system cannot be disabled now From Xiang + Xiao. + + * C Library/Header Files: + + - getcwd(): Remove stray sched_unlock(). Also fixes several typos. + From Juha Niskanen. + - date(), hostname(): Fix portability issue with date, hostname From + David Alessio. + - libs/libxx/Kconfig: Automatically select CONFIG_CLOCK_MONOTONIC when + CONFIG_LIBCXX is selected. Removed hardcoded -DCLOCK_MONOTONIC from + CFLAGS in Make.defs of several configurations. That definition is + now automatically adding this define when CONFIG_LIBCXX=y. From + Daniel Pereira Volpato. + - libs/libxx/Kconfig: CONFIG_LIBC_LOCALE is needed to build libcxx. + A math library is also needed, however, there are various ways to + provide a math library so CONFIG_LIBM is not now set. From Matias + N. + - libs/libc/symtab: Move symbol table generation into libc since the + address in symbol table should come from userspace binary for + PROTECTED build, not kernel binary. From Xiang Xiao. + - libs/libc/ Kconfig files: Disable EXECFUNCS_HAVE_SYMTAB for kernel + build. The symbol table doesn't have any meaning for kernel build + since all executable binary should be self contained. From Xiang + Xiao. + + - include/sys/time.h: According to earlier standards, usage of + select(), FD_CLR, FD_ISSET, FD_SET and FD_ZERO just need include + headers: sys/time.h, sys/types.h and unistd.h. So include + sys/select.h in time.h to compatible with it. Or mbedtls library + would build break in calling select() and FD_* related functions. + From liuhaitao. + + * Tools: + + - tools/configure.sh and configure.c: Do not remove CONFIG_SIM_M32 if + host is specified. From anchao. + - tools/Directories.mk: Remove FSDIRS/NOFSDIRS related logic/comments + since the file system can no longer be disabled now. From Xiang + Xiao. + - tools/Makefile.host: Add missing binaries from clean target. From + Gregory Nutt. + - tools/mkromfsimg.sh: Use sed to add const to ROMFS declarations so + that they lie in FLASH not RAM. From Bernd Walter. + - tools/nxstyle.c: Correct detection of missing blank line following + a block comment. From Gregory Nutt. + + * apps/ Build System: + + - Makefiles: Change ${shell pwd} to $(CURDIR) since pwd doesn't exist + on Windows From Xiang Xiao. + - Makefile: Fix warning: jobserver unavailable: using -j1. Add '+' to + parent make rule. From Xiang Xiao. + - apps/Application.mk: Correct an error in PATH usage. Use of + toolchain path causes make errors. From Gregory Nutt. + + * apps/tools: + + - tools/mkromfsimg.sh: Use sed to add const to ROMFS declarations so + that they like in FLASH not RAM. From Bernd Walter. + + * Examples: apps/examples: + + - apps/examples/mount: Replace illegal call to ramdisk_register() + with a call to boardctl(BOARDIOC_MKRD). From Gregory Nutt. + - apps/examples/nxlines/: Correct nxlines example program name. From + Gregory Nutt. + - apps/examples/nxterm/: PROGNAME, PRIORITY, STACKSIZE variable + names did not match declarations in Kconfig file. From Gregory + Nutt. + - apps/examples/romfs: Remove romfs_testdir.h. That file is + regenerated whenever the example is built and so should not be in + the repository. From Gregory Nutt. + + * Testing: apps/testing: + + - apps/testing/cxxtest/: Fix typo error in testing/cxxtest. From + Xiang Xiao. + - apps/testing/unity/: Fix the error when creating Make.dep. From + raiden00pl. + + * NSH Library: apps/nshlib: + + - apps/nshlib: Remove the inappropriate NSH_BUILTIN_APPS coupling. + From Xiang Xiao. + - apps/nshlib/: The NSH mkrd command was in violation of the NuttX + portable POSIX interface. It was calling the internal OS function + ramdisk_register() directly. Not only is this a violation of the + interface specification, but also prevents use of mkrd in PROTECTED + or KERNEL builds. With this change, the NSH mkrd command now uses + the BOARDIOC_MKRD boardctl() command. This command is available in + all build modes. The effect of this change is to move the heart of + the NSH mkrd command into to OS and provide user-space access via + boardctl(). From Gregory Nutt. + - apps/nshlib/: Replace direct calls to romdisk_register() with + indirect calls via boardioctl(BOARDIOC_ROMDISK). This not only + fixes the violation of the portable POSIX OS interface, but also + permits use of ROM disks in PROTECTED and KERNEL modes. From + Gregory Nutt. + - apps/nshlib/: Add missing NSH_DISABLE_DMESG from Kconfig. From + Juha Niskanen. + + * System Utilities: apps/system: + + - apps/system/cle/: This change modifies the cle to use the streams + file interface more consistently and has removed the observed race + conditions. It was previously a mix of streams and fileio. It + also simplifies the VT100 cursor position handling. From Dave + Marples. + - apps/system/composite: Remove usb serial loopback test code we can + achieve the same effect by cat or dd command. From Xiang Xiao. + - apps/system/cu/: (1) Fix early exit. getc(stdin) can return 0 the + first time around. (2) Set optind to zero. getopt() was being + left in a bad state, causing parsing errors on second use. (3) Fix + priority of cu_listen(). (4) Add suppor for -h. From David + Alessio. + - apps/system/lzf/: Check the protection by CONFIG_SYSTEM_LZF != + CONFIG_m (not elf binary) instead of CONFIG_KERNEL_BUILD. From + Xiang Xiao. + - apps/system/spi: Correctly parse exch txdata args, if any. Should + always call the board's deselect From David Alessio. + + * File System Utilities: apps/fsutils: + + - apps/fsutils/passwd/: Use named semaphore by checking + CONFIG_FS_NAMED_SEMAPHORES instead of CONFIG_KERNEL_BUILD. From + Xiang Xiao. + + * Network Utilities: apps/netutils: + + - apps/netutils/cjson/Makefile: Fix the error when creating + Make.dep. From raiden00pl. + + * Graphics: apps/graphics: + + - apps/graphics/twm4nx/: Fix a recently introduced error that broke + all Twm4Nx configurations. From Gregory Nutt. + - apps/graphics/traveler/: Replace direct calls to romdisk_register() + with indirect calls via boardioctl(BOARDIOC_ROMDISK). This not only + fixes the violation of the portable POSIX OS interface, but also + permits use of ROM disks in PROTECTED and KERNEL modes.

In + * general, there are four forms of the debug macros: + * + * [a-z]dbg() -- Outputs messages to the console similar to printf() except + * that the output is not buffered. The first character indicates the + * system system (e.g., n=network, f=filesystm, etc.). If the first + * character is missing (i.e., dbg()), then it is common. The common + * dbg() macro is enabled by CONFIG_DEBUG. Subsystem debug requires an + * additional configuration setting to enable it (e.g., CONFIG_DEBUG_NET + * for the network, CONFIG_DEBUG_FS for the file system, etc). + * + * In general, error messages and output of importance use [a-z]dbg(). + * [a-z]dbg() is implementation dependent but usually uses file descriptors. + * (that is a problem only because the interrupt task may have re- + * directed stdout). Therefore [a-z]dbg() should not be used in interrupt + * handlers. + * + * [a-z]vdbg() -- Identical to [a-z]dbg() except that it also requires that + * CONFIG_DEBUG_VERBOSE be defined. This is intended for general debug + * output that you would normally want to suppress. + * + * [a-z]lldbg() -- Identical to [a-z]dbg() except this is uses special + * interfaces provided by architecture-specific logic to talk directly + * to the underlying console hardware. If the architecture provides such + * logic, it should define CONFIG_ARCH_LOWPUTC. + * + * [a-z]lldbg() should not be used in normal code because the implementation + * probably disables interrupts and does things that are not consistent with + * good real-time performance.
