I'm new to embedded linux. To start with, I have nanopi fire 3 and smart 6818 cards, but I cannot access gpio pins with any gpio library. Why doesn't the NPi-GPIO library work with these cards? At first I was using the lubuntu version, I tried a lot there, but I couldn't. Now I'm trying to do something using armbian version 21.04. I'll post the problem I'm facing below. Thank you in advance for your help.
