Export GPIO then you can control GPIO from user space through sysfs.
For example:
GPIO ID:PY.02
Export PY.02
# echo PY.02 > /sys/class/gpio/export
1. Set GPIO direction to output mode
# echo "out" > /sys/class/gpio/PY.02/direction
# echo 1 > /sys/class/gpio/PY.02/value
# echo 0 > /sys/class/gpio/PY.02/value
