Using shell script to control LEDs from the Yocto system powering the Intel Galileo board. Using the documentation from Sergey’s Blog. Full shell script bellow:

#!/bin/sh

# gpio17 = Galileo pin 5
# gpio24 = Galileo pin 6
# gpio27 = Galileo pin 7

for i in 17 24 27; do
  echo out > /sys/class/gpio/gpio$i/direction
  echo strong > /sys/class/gpio/gpio$i/drive
done

for i in `seq 5`; do
  echo 0 > /sys/class/gpio/gpio17/value
  echo 0 > /sys/class/gpio/gpio24/value
  echo 0 > /sys/class/gpio/gpio27/value
  sleep 1
  echo 1 > /sys/class/gpio/gpio17/value
  echo 1 > /sys/class/gpio/gpio24/value
  echo 1 > /sys/class/gpio/gpio27/value
  sleep 1
done
