GPIO data is not getting reflected on the external board pins

Hi Sir/Madam,

  GPIO output register data is not getting reflected on the pins,

I have followed all the instructions provided in the technical reference manual of OMAPL13X for initializing the board pins to work as GPIO.

i.e. 1.  I have initialized the OMAP-L13X.

      2.  I have enabled the GPIO in PSC registers

      3.  I have also selected a GPIO pin 0 of register bank 8.

      4.  I tried toggling the pin HIGH and LOW.

     5.  But the same is not getting reflected on external pins provided on the board for testing purpose.
