We are facing problem while glowing LED on GPIO line with below details * Setup Details : Beagle Board-Xm Rev-A3 Ubuntu 11.04 Kernel Version 3.1.4-x6
Question We Executed the below command $ cd /sys/class/gpio $ ls export gpiochip128 gpiochip192 gpiochip64 unexport We have attached the LED to pin no: 24 & 28. According to schematic pin no:24 is connected to gpio168. With the above output we are unable to glow LED. Are we missing any driver or setting?
