Problems using CubeMX with ST Edge AI for validation of an ONNX model for Nucleo-N657X0-Q

[diama13]

Hello,

I’m encountering an issue when trying to validate an ONNX model using CubeMX with ST Edge AI for the NUCLEO-N657X0-Q board.

Here are the steps I followed:

1. I started the project in STM32CubeMX using the Board Selector.

2. I chose to create the project with Secure and Non-Secure domains.

3. I kept the default board configuration for NUCLEO_N657X0-Q.

4. Under Middlewares and Software Packs → X-CUBE-AI, I selected version 10.1.0 (STMicroelectronics.X-CUBE-AI) and enabled it. In the Artificial Intelligence section I enabled the Core, while in the Device Application I selected Validation 

5. Whether I enable or disable the “Optimal Clock Configuration” option, the result is the same.

The problem:
CubeMX gets stuck and does not continue to complete the process. There’s no specific error message — it just hangs indefinitely.

Any advice or workaround would be appreciated.
Thank you

Hello @diama13,

I would suggest looking at this:

How to build an AI application from scratch on the... - STMicroelectronics Community

The N6 is pretty badly supported by cubeMX...

You can also use the st edge ai core CLI directly to validate a model:

Home - ST Edge AI Developer Cloud

The steps are:

• generate
• flash the validation script
• validate on target

Have a good day,
