Build Error in STM32H747-DISCO Project with TouchGFX, CubeMX, and FreeRTOS

[Kenwang]

Hi all,
I encountered a build error while developing a TouchGFX project for the STM32H747-DISCO board. I followed these steps:

Steps to Reproduce:

1. Create a TouchGFX Project:

   • Used TouchGFX Environment on Windows to generate an empty STM32H747-DISCO project.

   • Added a background image and an Analog Clock.

   • Set the initial time of the clock to 00:00:00.

   • Clicked "Generate Code".

2. Modify the Project in STM32CubeMX:

   • Opened the project directory.

   • Used STM32CubeMX v6.14.0 to open the CubeMX project file.

   • Added the following peripherals:

     • CM4: RTC, OpenAMP, FreeRTOS

     • CM7: OpenAMP

   • Clicked "Generate Code" again.

3. Build in STM32CubeIDE:

   • Opened the project in STM32CubeIDE v1.18.0.

   • Attempted to build the CM7 project.

   • Encountered the following build error:

Build Error Output:

Questions:

1. Why am I getting "undefined reference" errors related to TouchGFX components?

2. Could this be an issue with the integration of CubeMX and TouchGFX?

3. Is there a recommended workflow to correctly integrate FreeRTOS, OpenAMP, and RTC with TouchGFX?

4. Do I need to manually add missing TouchGFX files or update any settings in CubeIDE?

I would appreciate any suggestions or solutions to resolve this build issue. Thanks!

Hello @Kenwang 

Could you attach your ioc file so we can investigate the issue?
