Hi,
I’m working with an STM32MP157D-DK1 board and attempting to connect to it using STM32CubeProgrammer. The board is powered properly (measured voltage: 3.23V) and ST-LINK is recognized by the software.
However, the debugger is unable to detect the Cortex-M4 core. I suspect the issue is that Linux is still holding the M4 core in reset, preventing the debug probe from halting or accessing it.
Does that sound like a reasonable cause? If so, could you please advise on the correct steps to release the M4 from reset and enable debugging access?
For context, I’ve already tried multiple combinations of ST-LINK connection settings (mode, reset mode, frequency), but none were successful.
Thank you for your help!
