Hello @KevinFFF . Thank you for your reply.
- Can you lease explain what do you mean by
Maybe you need to configure it in device tree for the trigger type.. The pin is able to detect a square wave right now - what other configuration do I need. - Which are the AON pins ? According to this , all pins which have the same letter twice in their SoC GPIOPort # are AON pins like AA, BB, CC, DD - pin 3,5,16,27,28,29,31,32,33,37 . Are all these AON pins ?
