Missing header file mw_stm32_utils.h when generating C code for STM32 nucleo board using embedded coder

Hi,

I am generating code from a Simulink model using embedded coder support package for STM32 processors. The generated code contains a dependency on mw_stm32_utils.h, but this file does not exist in the generated output. Because of that I can't build the project.

The dependency appears in the generated model.h header file:

#include "mw_stm32_utils.h"

The only files generated were model.h, model.c and rtwtypes.h. So my question is were does this dependency come from?

I attached the generated source files to this post.

Thanks you.

Try using packNGo to package all code to relocate it to a different environment:

Unfortunately, the dependency persists even when using packNGo or the 'Package code and artifacts' option. I tested this with different compilers and both C and C++, but the issue remains.

Also when setting minimalHeaders to false?

If yes, please create a Technical Support case for your issue.

I found this header file here:

C:\ProgramData\MATLAB\SupportPackages\R2025a\toolbox\shared\supportpackages\stm32\include

add this directory to the include path should work.
