Hello,
I'm having trouble getting the CubeMX code generation to work reliably with X-CUBE-AI package.
After first adding X-CUBE-AI to the project, and adding one of the models from the ST model zoo, i get this warning:
If i click Yes, the code generation takes about 5 minutes and works.
Note that in the above picture, X-CUBE-AI ExtMemLoader is selected. This is also where the warning comes from. AFAIK, i don't need X-CUBE-AI ExtMemLoader, just the Application. If i remove the checks from the checkboxes "Artificial Inteligence X-Cube-Ai" and "Device Appliccation", and then reopen MX, the X-CUBE-AI ExtMemLoader will disappear, and just the X-CUBE-AI Application remains. However, after trying to generate code with that setup, the code generation hangs to the below phase of code generation:
At that state, the OpenJDK Platform binary uses over 6000 MB of RAM, and about 10% of my CPU but seemingly nothing happens. I waited over the weekend to see if the generation would finish but it did not, then I retried multiple times, waiting about 20 minutes each time and it always hangs there.
Also there are some paths in the mx-generated.cmake which are wrong i think, as the code fails to build:
[0/1] Re-running CMake...Build type: Debug

but builds after adjusting the paths:
and fixing missing include in generated app_x-cube-ai.c file

The issue is that LL_ATON_DECLARE_NAMED_NN_INSTANCE_AND_INTERFACE is not found, but after adding
#include "ll_aton_rt_user_api.h" the project finally builds.
Here is the X-CUBE-AI Application config:
The model is from here https://github.com/STMicroelectronics/stm32ai-modelzoo/blob/main/audio_event_detection/yamnet/README.md
Thanks!
