Debug issue on STM32N6570-DK: Target not responding

[yangweidage]

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!

Hello @yangweidage,

I do not reproduce the issue.

I did try with the version 2.1.1 of the package that came out 5 days ago. Maybe explaining the difference.

GitHub - STMicroelectronics/STM32N6-GettingStarted-ObjectDetection: An AI software application package demonstrating simple implementation of object detection use case on STM32N6 product.​

I just:

1. cloned the repository
2. opened stm32cubeProgrammer
3. downloaded the weights in /binary/STM32N6570-DK_network_data.hex
   Select the external loader first:
   
4. I opened the project in stm32cubeIDE 1.18.1 (Are you using the 1.19?)
   The project being in \Application\STM32N6570-DK\STM32CubeIDE\.project
5. Then I set a debug point in main.c Run_Inference()
6. Launched the debug

I have no issue stepping over it.

Could you confirm that it is what you did and detail the versions of the tool you are using please?

Have a good day,

Julian
