We are wanting to configure pin 134 on our board for GPIO.
We consulted https://docs.toradex.com/102075-colibri-imx6-datasheet.pdf, and (if not wrong) found on page 16 that pin 134 corresponds to NAND_DATA01.
So, we added MX6QDL_PAD_NANDF_D1__NAND_DATA01 in pinctrl_gpio_1 in arch/arm/boot/dts/imx6qdl-colibri.dtsi, re-compiled and flashed the latest uImage and imx6dl-colibri-eval-v3.dtb
Thereafter, following is done after boot, and observed :
cd /sys/class/gpio echo 134 > export echo out > gpio134/direction echo 1 > gpio134/value cat gpio134/value 0
As is seen, gpio134/value still emits a 0.
What are we missing?
Please find the relevant files here
Will be grateful for pointers.
Thanks and Regards,
