Like if I set use following, the PH1 never gets HIGH
same goes for PC8 and PC9 as input, but they are always HIGH, never goes lowPinMode(PH1, OUTPUT);
digitalWrite(PH1, HIGH);
any idea how to make it work ?

PH1 is not connected to crystal, it should be but 25Mhz Crystal is not mounted soldered and nor its solder bridges.ag123 wrote: ↑Tue Nov 16, 2021 7:42 am maybe you'd need to check schematics etc to see if something is connected there.
PH0 and PH1 is your HSE crystal oscillator
PC14 and PC15 is your LSE 32 Khz crystal oscillator
check the specs

I'm using both CN11 and CN12. Yes you are right, PC8 and PC9 have SBs DNF by default. I was focused on PF14, I forgot to check these 2.
