    Intel Galileo board interface using sysfs as a root


      HI guys,

      i wanted to program the GPIO froml Linux.

      so as it was given in this link.




      i tried some of these commands mentioned to enable the GPIO control using sysfs.

      root@clanton:~# echo -n "27" > /sys/class/gpio/export

      but it is not working.

      the response is like:

      echo : write error : Device or resource is busy

      what am i missing.


      Help please i am stuck here.

      i am using intel galileo

      and i am booting the linux from the SD card
