All functions with Interrupt handling files like the STM32H7XX_IT.C must be marked as __weak

[Rajeev Arora]

Dear @Khouloud ZEMMELI​ 

Please review my below request. The STM32CubeMX generated code does not mark functions present with the Interrupt Related C file as __weak.

https://github.com/STMicroelectronics/STM32CubeH7/issues/175

Please help fix the issue.

Thanks,

Functions in STM32H7XX_IT.C are meant to be modified for your application, hence the inclusion of USER CODE sections. They are part of your user code and are deliberately not marked weak.

I fully agree they should be marked as "__weak". I have an established set of approved handlers for projects that reside in a library. There would be nothing wrong , as far as I can tell, having these functions marked as such. I honestly don't understand the reason for it being otherwise. Is there a way I can change a template so that this is not the case?

I suppose that someone that didn't have their own library that implemented these handlers would then end up with __weak versions in their USER CODE and __weak versions deep in the HAL/LL... and then which one would the compiler choose?
