I don't know why, I think after doing "sudo apt update/upgrade" (but I'm not sure), the wiringOP library on "orange pi 5" with Armbian 23.02.2 doesn't work anymore. If I run the command "sudo gpio readall" I get the following output:
Oops: Unable to determine board revision from /proc/device-tree/system/linux,revision
or from /proc/cpuinfo
-> No "Hardware" line
-> You'd best google the error to find out why.
Can anyone help me solve this problem?
