X-CUBE-N6-AI People Detection Demo Shows Only Gray Screen When Debugging in CubeIDE

Background:
I am using the STM32N6570-DK board and trying to use the NPU for acceleration. For now, I want to run the official demo (x-cube-n6-ai-people-detection-tracking-main) to learn and verify the workflow. However, I have encountered some issues:

1. When I debug and run the official x-cube-n6-ai-people-detection-tracking-main example directly in CubeIDE, the screen turns on but it only shows a gray display, as if the program is blocked or stuck somewhere.

2. I have already programmed the network_data-dk.hex file to the board using STM32CubeProgrammer.

I would like to know why the demo is not running correctly and what might be causing the program to get stuck.

Hello @cmcross_zaizai,

 

I just cloned the repository and tested 2 things:

  • Flash all 3 binaries and run the application => no issue
  • Flash the network_data-dk.hex and run the application from cubeIDE => no issue

 

Could you please try to start from scratch again?

Can you tell me if when just using the 3 binaries, you get the application correctly running?

 

Have a good day,

Julian

Hi @mls,

 

What do you get if you just flash the 3 binaries? It is important to know if this comes from the board or the compilation.

 

@cmcross_zaizai, did you solved your issue?

 

Have a good day,

Julian
