Beginners • CM5 - IO Configuration for GPIO 14

Hi there,

would like to use the GPIO14 as a "normal" input - just need to read out the current state of the input which acts a a user button. Unfortunally when I read out the pin with the pin in always HIGH despite the hardware works so the button is low-active and I already measured the voltage on the hardware side.

I think there might be a configuration issue because the GPIO14 is normally used for UART - i guess.

I already tried to disable uart in with but it doesn't work.

Can you please give me a hint how to configure gpio14 as normal input and what I need to take care of.

Thanks and kind regards
