working on STM32N657X0H3Q (Nucleo-N657X0-Q board)

Hi!

It might be a *** beginners question but I'm quite lost...

I'm trying to deploy my .ONNX model on my new NUCLEO-N657X0-Q board. The MCU on it STM32N657X0H3Q, seems to have 4Mb of RAM and no flash, but the board itself has 512Mb octaflash memory on it. My model is calculated as 2.71 MB of flash memory and 402 Kb of RAM. The ST edge developer tool claims that my board doesn't have enough resources and it won't create a suitable STM project for the IDE.

My question is - is there a way to work with the board on AI models? is it a bug in the software or am I doing something wrong?

Thank you!

Amir

Hi @amirkfir,

Based on the numbers you give, this seems correct.

What are you doing exactly (what tool are you using)?

Maybe this can help you:
