BeagleBone Black User LEDs

The four blue user LEDs on the BeagleBone Black are wired to GPIO1_21 through GPIO1_24. To control the LEDs from userland, set gpio=YES in rc.conf and add this to /etc/gpio.conf:

gpio1 21 set out USR0
gpio1 22 set out USR1
gpio1 23 set out USR2
gpio1 24 set out USR3

After rebooting, the LED states can be controlled with gpioctl(8).

# turn the USR0 light on
gpioctl gpio1 USR0 on

# turn the USR0 light off
gpioctl gpio1 USR0 off

# toggle the USR0 light state
gpioctl gpio1 USR0 toggle

Sample dmesg
