Transplant STM32N6 Model Zoo AI camera code into Touchgfx project

[dianzijun]

I have been using STM32N6 to conduct model training and deployment for the model zoo. Now, I want to transfer the generated code to my TouchGFX project for embedded use in the CubeIDE environment. However, when I am transferring several files, before the transfer, the original files did not have this error, but after the transfer, there is this error and it is particularly common, mostly for the official-generated code. As follows:

  When these files are transferred：

After the transplantation was completed, an error occurred：

Hello @dianzijun,

When you copied files from the model training project to your TouchGFX-based CubeIDE project, you likely:

• Missed important HAL/driver headers, or
• Lost include path settings in .cproject, .project, or Makefile.

These headers and types are not auto-discovered — they depend on include paths configured in the CubeIDE or Makefile.

Check that these files exist in your project:

• Drivers/STM32N6xx_HAL_Driver/Inc/stm32n6xx_hal_def.h
• Drivers/STM32N6xx_HAL_Driver/Src/stm32n6xx_hal.c
• Any other HAL .h/.c files that are referenced in the .h file showing errors.

Go to Project Properties in STM32CubeIDE:

Right-click your project → Properties → C/C++ General → Paths and Symbols → Includes
Add the following (if not present):

• ${ProjDirPath}/Drivers/STM32N6xx_HAL_Driver/Inc
• ${ProjDirPath}/Drivers/CMSIS/Device/ST/STM32N6xx/Include
• ${ProjDirPath}/Drivers/CMSIS/Include

Any custom middleware paths like:

• ${ProjDirPath}/AI_bsp/Camera_Middleware/inc
• ${ProjDirPath}/AI_bsp/Camera_Middleware/STM32N6570-DK/inc

Ensure stm32n6570_discovery_conf.h Exists:
Search your original project for the file stm32n6570_discovery_conf.h and copy it to the appropriate location, for example: <YourProject>/AI_bsp/Camera_Middleware/STM32N6570-DK/inc/
If it's board-specific, you might also need to copy:

• stm32n6570_discovery.c
• stm32n6570_discovery.h

Make sure these are added to your project and paths are included

You can also:

• Do a Project > Clean
• Then Project > Build

Have a good day

My problem has not been solved yet.Several files in the compilation project report the error "unknown type name 'HAL_StatusTypeDef'". When pressing F3, the definition can be seen. Redefining it in other .h files results in a duplicate definition error. I don't know what the reason is?Could you please show me? I'm really confused right now.

Hello @dianzijun,

HAL_StatusTypeDef is declared and defined in the file stm32n6xx_hal_def.h.

This file is located in <your_project>/Drivers/STM32N6xx_HAL_Driver/Inc/stm32n6xx8hal_def.h.

Did you include <your_project>/Drivers/STM32N6xx_HAL_Driver/Inc on "Paths and Symbols" under the "Includes" window?

• Right click on your project in STM32CubeIDE

• Click properties
• Go to C / C++ general
• Path and includes

• Add the path to the files missing, for example: <your_project>/Drivers/STM32N6xx_HAL_Driver/Inc
• (You may have to add others)

If this is already set or does not work, you may try ask this forum board in the meantime: STM32 MCUs Software development tools - STMicroelectronics Community

Havea good day,

Julian

Sorry, it hasn't been resolved yet. I can send the file to you. Could you please take a look and let me know if there are any issues? I've been stuck like this for a week and I'm really grateful to you.
