下载软件 (二) openocd

• 简介

openocd 可用来在在linux上运行,做应用,打开相应的调试器对应文件,然后通过调试器控制stm32
对应cmsis-dap 来说 不需要驱动,只需要应用openocd

调试器对应文件为
open("/dev/hidraw1", O_RDWR)            = 3

-f interface/cmsis-dap.cfg 调试器为cmsis-dap
-f target/stm32f4x.cfg 		目标芯片为 stm32f4系列
-c init  不可少
-c halt  halt住核心
-c "flash write_image erase /home/pop/stm32/stm32_template/stm32f407_template/TEST.hex" 下载hex文件到mcu
-c reset 让mcu reset
-c shutdown 退出openocd // 关闭服务器.
