Hi, I have tried the example, checked the one here , but still I cannot have gpio working on my udoo neo full with udoobuntu2 beta 5. Tried the led example http://www.udoo.org/tutorial/getting-started-with-arduino-ide-on-udoo/ with a working led, but it does not switch on. Just for clarification, according to this, gpio142 is the pin #36 logged as root echo 142 > /sys/class/gpio/export echo out /sys/class/gpio/gpio142/direction echo 1 > /sys/class/gpio/gpio142/value with a little breadboard with a led connected to udoo GND and pin36 (J5), nothing happens. Am I forgetting something?
The table you are looking at is for udoo, not udoo neo, please look at this for the correct GPIO numbers. http://www.udoo.org/docs-neo/Hardware_&_Accessories/Gpio.html
