[OpenOCD-user] TARGET: stm32f4x.cpu - Not halted

[Christoph K. <ku...@ku...>]

I have the following setup:

Nucleo stm32f411 board. ST-LINK on board wired to external device. Attached as the external target is a cheapo china board (STM32-407-DIYMORE) .
Attached is the OpenOCD server log as well as the gdb session.

I’m wondering about the following effect/message:
