背景 & 现状：
|
||
|
||
目前Hi3861使用Hiburn.exe工具对设备进行烧录，烧录完成后重启设备自动执行测试用例，xDevice测试框架将收集测试用例执行数据，将其数据处理、结果解析，生成测试报告。但由于各厂商L0板子与Hi3861烧录方式不尽相同，为了兼容不同厂商也能在xDevice测试框架上执行，测试框架提供了支持调用厂商升级脚本对设备实现烧写和用例执行。
|
||
|
||
前提：
|
||
|
||
1. 串口可以实现AT命令（借助其它工具）重启和复位；
|
||
2. 刷机工具支持命令自动刷机；
|
||
|
||
以下是Hiburn和升级脚本两种烧录方式，请自行选择合适的烧录方式：
|
||
|
||
- Hiburn工具烧录(命令行烧写)
|
||
|
||
命令行烧录和用例执行步骤：
|
||
|
||
1. 设备复位
|
||
|
||
AT+RST=20000000 -》复位设备，等待20s在复位，否则复位不成功
|
||
|
||
2. send file
|
||
|
||
发送bin文件到设备，在Window环境下，Hiburn.exe支持以命令行的方式调用，调用命令如下：
|
||
|
||
```shell
|
||
Hiburn.exe params
|
||
```
|
||
|
||
命令之间用空格隔开，如果命令带有参数，命令和参数之间作用冒号隔开，示例如下：
|
||
|
||
```
|
||
Hiburn.exe -com:20 -bin:C:\test_bin\xxx.bin -signalbaud:115200
|
||
```
|
||
|
||
Hiburn.exe烧写命令参数
|
||
|
||
| 命令 | 参数 | 说明 |
|
||
| ------------ |------------------|------------------------------------------------|
|
||
| -com | x | PC端的串口号（例如1） |
|
||
| -bin | path\upgrade.bin | 固件包upgrade.bin的绝对路径，固件包的名称和文件类型根据各产品实际情况可能有所不同 |
|
||
| - signalbaud | 115200 | RomBoot下传输固件包时的串口波特率，默认为 115200bit/s |
|
||
|
||
3. 重启设备
|
||
|
||
与串口建立连接后发送[239, 190, 173, 222, 12, 0, 135, 120, 0, 0, 97, 148]重启设备，然后开始自动执行用例，将执行数据返回给测试框架。
|
||
|
||
Command – Reset对应的AT命令如下
|
||
|
||
```shell
|
||
['0xef', '0xbe', '0xad', '0xde', '0xc', '0x0', '0x87','0x78', '0x0', '0x0', '0x61', '0x94']
|
||
```
|
||
|
||
备注：如果开发板支持Hiburn方式烧录，不需要提供升级脚本。
|
||
|
||
- 升级脚本烧写
|
||
|
||
1. 初始化升级类
|
||
|
||
建议：文件名和类名以名字后缀区分不同厂商,如UpGradeDeviceHuawei
|
||
|
||
初始化升级类，如UpGradeDeviceXXX
|
||
|
||
输入：串口号、波特率、执行文件bin路径、烧录工具名称、其它参数等
|
||
|
||
如下图：
|
||
|
||
|
||
|
||
2. 调用方法burn实现烧写
|
||
|
||
该函数主要是对设备进行复位、擦除、烧写设备，烧写成功返回True，失败返回False
|
||
|
||
|
||
|
||
1) 函数_reset()
|
||
|
||
发送命令让设备复位
|
||
|
||
|
||
|
||
2) 函数_upgrade_device()
|
||
|
||
对设备进行烧录
|
||
|
||
|
||
|
||
3. 调用方法reset_device重启设备
|
||
|
||
该函数主要是重启设备，然后自动执行用例，返回用例执行数据给测试框架。
|
||
|
||
|
||
|
||
1 ) 返回重启设备的AT命令，由xDevice框架做重启设备的操作
|
||
|
||
|
||
|
||
2) 在不知道AT命令情况下，借助三方工具重启设备，将执行用例的数据返回给xDevice做处理
