GPIO Problem - pins don't work?

I am using a cubecell dev board to transmit some sensor readings and it all works great. For the sensor, I am using the ADC pin as it is the only that I was able to use. I’ve tried simple things like to blink an LED or read a simple button, but for me the pins addressed via GPIO1 for example do not work.

I tried multiple GPIO pins now - all don’t work. Any idea? Any super simple test I could run?

My goal is to read the temp of a DS18B20 temp sensor - works great on an arduino so no I am porting it to the cubecell dev board.

Could you paste your code?

works now. I think initBoardMcu was missing - thx!
