In our project I use STM32H573VIT6 LDO uC. We have a problem with the PB14 pin. We use 3 pins for LED control (PB10, PB13 and PB14, see photo). The problem with the PB14 is that the LED lights up dimly without code initialization. If PB14 is initiali...

Thank you @Tesla DeLorean And what configuration do the GPIOs have then?

I think the discussion is going in the wrong direction.Once again:1. The board is only powered, no code downloaded to the flash, nothing connected, the LED on PB14 lights up dimly. As far as I know, all GPIOs should be initialized as inputs in this s...

As I said, it is the same state whether code is not loaded (not programmed) or code is running.
