configuring GPIO in CS331-C246/Q370 MicroATX

Hi,

I am using CS331-C246/Q370 MicroATX Industrial Motherboard loaded with ubuntu 18.04. It has 8 GPIO PINS (DIO0 to DIO7), we are using switch to enable and disable the GPIO pin and we are trying to read the value by using "cat /sys/class/gpio/gpioN/value" but value is not changing by toggling the switch. we checked with all the GPIO pins from (148-511)

In /sys/class/gpio three files are there 1)export  2)gpiochip148 3)unexport

in /dev gpiochio0

1) GPIO pin numbers to read the value  from /sys/class/gpio/gpioN/value in linux

Hello KUMAR


Thank you for posting in the Intel Community. 


I would recommend confirming the pin layout with the motherboard manufacturer and the appropriate steps to complete the test that you are running on the systems.
