undefined reference to `ExitRun0Mode'

Hi,

I've installed the CubeIDe rel 2.0.0 and the CubeMX rel 6.16.0; when I build my project this error appears: undefined reference to `ExitRun0Mode'.

 

May you help me ?

 

Thank you, CarloV

    I think my previous replies answer that question.

    - You need to remove the old "system_stm32h7xx.c" file.

    - Generate the code with CubeMx by pointing to the latest CubeH7 version: the new updated system_stm32h7xx.c containing ExitRun0Mode() will be generated and added to your project.

    - Remove HAL_PWREx_ConfigSupply() if you have its call in SystemClock_Config() in your previous implementation.

    Here is a definition of that file. Maybe it's the one you want.

    https://github.com/STMicroelectronics/STM32CubeH7/blob/46631c3dab1edbe412c613add345bfbf1d2c5e2e/Projects/STM32H7B3I-DK/Examples/BSP/Src/system_stm32h7xx.c#L359

     

    Would be better for you to provide your IOC or explain how you project was created. If the function is there, it should be found.

      Thank you, I build my project using the 1.9.0 CubeIde release, including the IOC file, and worked good. The issue appeared after the 1.2.0, it requires the CubeMX to build the IOC; I imported the old project.

      Hello,

      ExitRun0Mode() was introduced (if I'm not mistaken) in V1.7.0. So please update your CubeHAL repositry folder to the latest version.

      I checked my "system_stm32h7xx.c" file and I haven't find the "ExitRun0Mode" function...

      Try to remove system_stm32h7xx.c and re-generate the code again in CubeMx. But be sure you are pointing to the latest CubeH7 version:

      And please remove HAL_PWREx_ConfigSupply() if you have its call in SystemClock_Config(). Setting the power in SystemClock_Config() is an old implementation.

      If I open your IOC and generate code and compile the project, it (mostly) works.

      Except that you have do not generate main checked, so it doesn't generate that.

      If I add main(), it compiles.

      ExitRun0Mode is generated and present in system_stm32*.c

      I wonder if you are not regenerating code.
