I am experiencing beaglebone black and using it on Debian. I figured out that there are directories for gpio pins and leds. When i am in these directory by changing value and direction field i can use it as what i want. But i want to be use gpio pins as same as led pins. Means that, there is no any “trigger” for gpio pins but i wannt to add like “heartbeat” trigger to any pins,non-leds. Is there anyway to get it?
Or i also figured out “device tree overlay” structure during my web searching like here, there are some sample of .dts files but i can not find that how can be done adding trigger to any pins in means of syntax. How can i use any pins that triggered by heartbeat,cpu0 etc?
Thanks a lot,
