STM32N6 STEdge AI Core CM55 validation missing files

[berab]

Hi all,

I was following this guide for CM55 validation, yet when I run 

stedgeai generate -m <model-file> --target stm32n6 --binary --address 0x71000000 --memory-pool ./mypool_N6.json

It does compile, but at the end, I have several files missing, such as network_config.h, network_data*, and network_data_params*. 

This is the output I am getting.

I'd be glad if anyone has any idea how to fix it. Thanks :))

I ran the script without --binary and --address options, then network_data* files were generated. There are still missing files.

Hello @berab 

The files you are looking for are only available if you work with `legacy` api.

Please, could you retry with this command: 

stedgeai generate -m <model-file> --target stm32n6 --c-api legacy --binary --address 0x71000000 --memory-pool ./mypool_N6.json

Best regards,

Hi @hamitiya,

Thanks for the help. This generates these legacy files. The point is, I wasn't trying to run it in the legacy api. Yet, those files are included in CM55_Validation/armgcc/Makefile. Apparently, I can just remove the inclusion of network_data_params.c, and it compiles fine.

Yet, it seems I have to run stedgeai in legacy api mode anyway, since if I don't, i.e., if I run: 

stedgeai generate -m mymodel.onnx --target stm32n6 --memory-pool ./mypool_N6.json 

 I still get a compilation error due to some undeclared definitions in  app_x-cube-ai.h, such as:

../../../Applications/CM55_Validation/X-CUBE-AI/App/app_x-cube-ai.c:75:31: error: 'AI_NETWORK_MODEL_NAME' undeclared here (not in a function); did you mean 'STAI_NETWORK_MODEL_NAME'?
   75 |         .name = (const char *)AI_NETWORK_MODEL_NAME,
      |                               ^~~~~~~~~~~~~~~~~~~~~
      |                               STAI_NETWORK_MODEL_NAME

Best, Beran

Actually, it is a limitation of ST Edge AI Core.

For the option provided by this example, you need to force --c-api legacy.

Prior to 3.0, it was still the default option, since then, the default API is "ST-AI".

app_x-cube-ai is the application starter containing model declaration and it follows now the new API...

Since the tutorial is about CM55 Validation for STM32N6 Series, I would suggest you try STM32Cube AI Studio to generate a complete project

STM32Cube AI Studio- The next-gen stand-alone tool for embedded AI - STMicroelectronics

It will generate app_x-cube-ai.c for you and execute on target if any.

Best regards,

Yanis
