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.

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.
