The startup code paths in the cmake files for the H745 created with CubeMX v6.12 are incorrect.

[imagawa122]

H745 startup files are located in "CM7/Core/startup/startup_stm32h745xx_CM7.s" or "CM4/Core/startup/startup_stm32h745xx_CM4.s".

However, the build source path for the startup files in the mx-generated.cmake in each core's folder is ". /Startup/startup_stm32h745xx_CM7.s" or ". /Startup/startup_stm32h745xx_CM4.s".

Therefore, the cmake file must be changed to build.

Hello @imagawa122 

First let me thank you for posting.

I tried to reproduce the described behavior but the code is compiled correctly.

And after checking the mx-generated.cmake the startup file path is defined this way:

• ./Core/Startup/startup_stm32h745xx_CM7.s
• ./Core/Startup/startup_stm32h745xx_CM4.s

Could you provide a simplistic project showing this behavior?

BR,
Semer.
