$ openocd -f interface/stlink-v2.cfg -f target/stm32f4x_stlink.cfg
启动openocd server
2. 编写.gdbinit脚本
target remote localhost:3333
monitor reset
monitor halt
load
3.
$ arm-none-eabi-gdb example.elf
4.
(gdb) source .gdbinit
5. 设置断点
b main
monitor reset halt
6.
continue (这里没有run指令,只有c指令)
//注意设置断点后,一定要执行monitor reset halt指令,否则不会停在断点处!!!
openocd 操作stm32 flash命令:
1. openocd -f interface/stlink-v2.cfg -f target/stm32f1x_stlink.cfg -c init -c "reset halt" -c "flash erase_address 0x08000000 0x40000" -c exit
清空从0x80000000地址开始,长度为40000的flash地址
2. openocd -f interface/stlink-v2.cfg -f target/stm32f1x_stlink.cfg -c init -c "reset run" -c "mdw 0x08000000 0x10000" -c "exit"
将地址从0x80000000开始,长度为0x10000的内容打印到屏幕
