The project description file (.project) is missing for X-CUBE-AI validation

Associate II

I am trying to follow the "Getting started with X-CUBE-AI Expansion Package for Artificial Intelligence (AI)" document (User Manual UM2526), but I cannot validate the model on target.  Note that I'm using the STM32F746-DISCO instead of the recommended NUCLEO-F746ZG, but that's a minor difference.

I can sucessfully validate the model on desktop (using random numbers and real data), but get an error when trying to validate on target using the "automatic compilation and download" option.


CubeMX reports "Automatic build and run failed".

Consulting the STM32CubeMX.log file I see the following error:

2023-09-19 11:57:49,034 [ERROR] STM32CubeIDEBuilder:207 - !MESSAGE The project description file (.project) for 'mxAI1803873821400' is missing. This file contains important information about the project. The project will not function properly until this file is restored.

My project is named STM32F746-DISCO, not the random string of characters shown.  Even when I've used the "Generate Code" option to try to export to the CubeIDE, I don't get a .project file associated with 'mxAI1803873821400'. What am I doing wrong?
