Issue when compiling a project with TouchGFX and FDCAN Code Integration

Subject: Issue with Displaying Speedometer Values on STM32H747XIH6 Board

Dear ST Community,

I am currently working on a project involving the STM32H747XIH6 DISCO board, using TouchGFX to create a speedometer display. I am facing difficulties where the speedometer values are not being displayed on the screen. Additionally, I am encountering some errors during the build and execution process.

Project Setup:

  • Board: STM32H747XIH6
  • IDE: STM32CubeIDE with TouchGFX integration
  • Peripherals: FDCAN for receiving data (speed values)
  • Middleware: FreeRTOS and TouchGFX

Problems Encountered:

  1. The speedometer values are not updating on the display, despite the data being received via FDCAN.
  2. During the build process, I am receiving the following errors:
    • Undefined reference to __sf_fake_stdin, __sf_fake_stdout, and __sf_fake_stderr in FreeRTOS.
    • Undefined reference to HAL_FDCAN_Init.

Actions Taken:

  • Verified the initialization of FDCAN in both STM32CubeMX and in the code.
  • Checked that the necessary HAL drivers are included and compiled.
  • Ensured that the FreeRTOS configuration supports standard input/output, as indicated by the errors.
  • Cleaned and rebuilt the project, but the issues persist.

I would greatly appreciate any guidance or suggestions to resolve these issues. I am particularly interested in:

  • Resolving the linker errors mentioned above.
  • Ensuring that the FDCAN data correctly updates the speedometer widget in TouchGFX.

Best regards.

Hello,

Did you generate the GUI with TouchGFX designer tool before to compile the project?
