Help with .dts files (imx6)

I am using an imx6ulevk (no LCD connected). I'm trying to use a few of the LCD lines to toggle some LEDs that I've added to the board (specifically DATA00 - DATA02, aka GPIO3.5 - GPIO3.7).


I've modified the imx6ul-14x14-evk.dts file (attached as imxtul-oib.dts) and compiled it. Then I copy it to my NFS folder and run netboot on the evk to load the kernel, dtb file, etc.


I then go to /sys/class/gpio. I can export the GPIO pins (e.g. echo 70 > export) I'm using and write the direction and value settings, but the GPIO lines (LEDs) do not toggle.


Is there something else that I'm not doing, and is my .dts file ok?


Thanks in advance,
