Hi all,

     I would like to use USER1 and USER2 GPIO's provided on i.MX53 Quick start-R Board. In testing these GPIO's when I press the button it should be high on logic analyser but it is not becoming high, these Pins are always Low. But in boot-up initially they are becoming High. Should I need to do configure in Kernel while compilation. Could Some one help in Enabling this PINS.

     I couldn't find /sys/class/gpio file location.

     Thanks in Advance.
