GPIO usage from eclipse

Dear sir,

I have a Colibri iMX6DL 512MB V1.1A with Colibri Evaluation Board V3.2 running on embedded linux V2.7 provided by Toradex. I am using Eclipse for application development and i want to turn ON and OFF the GPIOs from my C code in eclipse.

I followed this link and i saw the ways to turn ON and OFF gpio pins from terminal and also from eclipse C code but when i tried the one from terminal, while

echo 148 > /sys/class/gpio/export

The terminal gives me write error: Operation not permitted, then i tried with eclipse and the code compiled successfully but no change in the gpio pin. I also tried with various pins the export command not working in both terminal and also from eclipse.

Thanks for your time

Hi @nishanth1829

Have you done the correct PinMuxing for Gpio 148?

You need to look in the Datasheet for the SODIMM you want to toggle. Then Mux it correctly to GPIO. Once this is done, you can compile the new Devicetree and flash it to the module.

Best regards,
