Unfortunately sharing drivers between different architectures is not possible, note that even between different STM32 families there are driver duplication. It could seems strange at first glance, but normally different chip families has small differences, then at end of day we end-up with tons of #ifdef and the code become really difficult to follow. In this case duplication is a good thing, but the bad thing is to keep these drivers in sync when someone find some issues. It requires manual comparison to spot some improvement in a driver that is missing in another one. BR, Alan
