Ah, I missed that you are controlling two different GPIO connected to the same pin. I don’t know why you keep on bringing stuff up like this, because any sensible developer would obviously avoid something like this. Gerald was attempting to bring out all the features on the AM335x even when he didn’t have sufficient connector pins. Clearly, if you want the one GPIO to be an output, the other must be configured as an input.
