Hey all,


I have been working on my custom board with imx233. During the boared design, I made some imx pins (as GPIO) to control other components on board.


The imx wiki page has all the instruction on how to use GPIOs in the user space on the following link:



But there is no option, or I can't see,  in LTIB config that allows to configure SYSFS

I mean I can't see this

Device Drivers --->
      --- GPIO Support
            [*] /sys/class/gpio/... (sysfs interface)

as mentioned in the wiki

so, how do I configure LTIB to export GPIO thru SYSFS?
