Use alternative pins [bugfix-2.0.x] (no replies)

Hi All,

Does anyone know how to select the alternative pin function when using the STM32F1 HAL?

I have made a custom board with an STM32F103RC and routed pins PB3, PB4, PA14 and PA15 to some of the stepper drivers. The problem is that the default functions for these pins are not IO but used for SWD and some other functions and would need to be remapped to the alternative function.

Any ideas or suggestions?
