我需要同时通过 2 个 ST-Link 连接到 2 个 STM32。我发现这里描述的这个问题。
但是,解决方案对我不起作用。
ST-Link ID1:55FF6B067087534923182367
ST-Link ID2:49FF6C064983574951291787
OpenOCD 配置文件:
source [find interface/stlink-v2.cfg]
hla_serial "55FF6B067087534923182367"
source [find target/stm32f4x.cfg]
# use hardware reset, connect under reset
reset_config srst_only srst_nogate
我得到:
$ openocd.exe -f stm32f4_fmboard.cfg
