RX System emulator
|
|
--------------------
|
|
|
|
Use the executable ``qemu-system-rx`` to simulate RX target (GDB simulator).
|
|
This target emulated following devices.
|
|
|
|
- R5F562N8 MCU
|
|
|
|
- On-chip memory (ROM 512KB, RAM 96KB)
|
|
- Interrupt Control Unit (ICUa)
|
|
- 8Bit Timer x 1CH (TMR0,1)
|
|
- Compare Match Timer x 2CH (CMT0,1)
|
|
- Serial Communication Interface x 1CH (SCI0)
|
|
|
|
- External memory 16MByte
|
|
|
|
Example of ``qemu-system-rx`` usage for RX is shown below:
|
|
|
|
Download ``<u-boot_image_file>`` from
|
|
https://osdn.net/users/ysato/pf/qemu/dl/u-boot.bin.gz
|
|
|
|
Start emulation of rx-virt::
|
|
qemu-system-rx -M gdbsim-r5f562n8 -bios <u-boot_image_file>
|
|
|
|
Download ``kernel_image_file`` from
|
|
https://osdn.net/users/ysato/pf/qemu/dl/zImage
|
|
|
|
Download ``device_tree_blob`` from
|
|
https://osdn.net/users/ysato/pf/qemu/dl/rx-virt.dtb
|
|
|
|
Start emulation of rx-virt::
|
|
qemu-system-rx -M gdbsim-r5f562n8 \
|
|
-kernel <kernel_image_file> -dtb <device_tree_blob> \
|
|
-append "earlycon"
