Debug issue on STM32N6570-DK: Target not responding

Hello,

I am working with the STM32N6570-DK board and running the STM32N6-GettingStarted-ObjectDetection example. When I debug the program in CubeIDE (The MCU runs in Dev mode), I encounter the following issue:

  • In the main loop, when the function LL_ATON_RT_RunEpochBlock is called, the debugger reports:

    Target is not responding, retrying...

  • At this point, pressing the NRST button on the board does not reset the MCU. 

  • The only way to recover is to power cycle the board.

Any suggestions would be greatly appreciated.

Thanks in advance!
