Not able to control PINS in IMX8ULP Custom Board

[dhruvinrajpura]

Hello,

I am using IMX8ULP custom board(MIMX8UD5D08SC), and in that I want to get status of 2 pins PTE11 and PTE14 from that I am able to get status PTE11 but not able to get status of PTE14,

I am attaching original dts file, modified dts file and patch that I applied and here are logs I am getting on console.

root@imx8ulp-9x9-lpddr4-evk:~# gpioget -c 0 11
"11"=active

//Pressing Button
root@imx8ulp-9x9-lpddr4-evk:~# gpioget -c 0 11

"14"=active
//Pressing Button
root@imx8ulp-9x9-lpddr4-evk:~# gpioget -c 0 14

Hello @dhruvinrajpura 

I hope you are doing very well.

Please share the logs of below command after boot:

$ dmesg | grep gpio

It make me thing that PTE14 is took by the &fec after boot.

You can see it here. 

Try disabling the fec or changing the iomuxc for fec,

Best regards,

Salas.
