gpio set error

[adityadotrastogi]

Hi, I am new to this board. Tried to port my code from to ROCK64. But even GPIO test file throws error. I have tried using different pins based on BCM,BOARD, Rock valid channels, but no luck. Any help on this is greatly appreciated.

Thanks

Try using SUDO while running the command. It worked in my case
