STM32: 使用openocd更新stm32f030F4固件

今天发现在Mac OS上使用port下载openocd软件,得到的软件版本号为0.7.0,通过它来更新STM32F030F4固件的时候,会出现如下错误信息:

$ openocd -f interface/stlink-v2.cfg -f target/stm32f0x_stlink.cfg -c init -c "reset halt" -c "flash write_image erase build/ch.bin 0x08000000 bin" -c "verify_image build/ch.bin 0x08000000 bin" -c "reset run" -c shutdown

可以看到是由于openocd版本太旧,没办法确认target的身份信息,看来得更新这个应用程序才行。openocd是开源项目,可以从官网上下载最新的代码进行编译,生成我们所需要软件。

  • 下载编译openocd

1. 使用git命令下载openocd源代码

$ git clone git://git.code.sf.net/p/openocd/code openocd

2. 下载openocd子模块:jimtcl, libjaylink,  git2cl代码

$ cd openocd
$ git submodule init
$ git submodule update

3. 编译及安装

$ ./bootstrap
$ ./configure
$ make && make install

最终openocd会安装在/usr/local/bin/目录下。

  • 通过openocd更新固件

我使用的是STM32F407 discovery上的ST-Link v2, 固件存放在build/文件夹下,名为ch.bin,更新的命令如下:

$ /usr/local/bin/openocd -f interface/stlink-v2.cfg -f target/stm32f0x_stlink.cfg -c init -c "reset halt" -c "flash write_image erase build/ch.bin 0x08000000 bin" -c "verify_image build/ch.bin 0x08000000 bin" -c "reset run" -c shutdown

从这里可以看到这里不但执行为更新固件的操作,同时还对之前更新的固件进行完整性验证。

之前没有注意到openocd推荐使用stm32f0x.cfg作为配置文件对stm32f0系列MCU进行操作,所以更新固件使用如下命令:

$ /usr/local/bin/openocd -f interface/stlink-v2.cfg -f target/stm32f0x.cfg -c init -c "reset halt" -c "flash write_image erase build/ch.bin 0x08000000 bin" -c "verify_image build/ch.bin 0x08000000 bin" -c "reset run" -c shutdown
