Check if power source is already configured on STM32H7 #428

Closed opkaizen closed 1 month ago

opkaizen commented 2 months ago

If the power source is already configured, writing on the register can cause a deadlock if the configuration does not match, which can be tricky to fix. This is the check that is done in the STM32 HAL library to avoid this.

I got this issue because the STM32H757 demo board and the STM32H745XI discovery board use the SMPS, and even though the power on reset configuration is LDO|SMPS, writing on LDO deadlocked my boards.
