How to access GPIO in iMX7ULP eval board

Hello,

I am working with im7ulp eval kit and wondering how to access any GPIO from linux terminal. Usually, there will be GPIO bank and port number (like GPIO2_IO31 in imx6) which we would convert into GPIO number and access using /sys/class/gpio interface.

 

Is there any similar way to access GPIOs (Port C,D,E,F in imx7ulp ) from linux ? (Also, if possible, Port A and B from M4 domain)

 

PS: I am using L4.19.35_1.1.0 package.

 

Thanks,

Jai Ganesh Srihdaran
