Hi.
After recent linux kernel upgrade ceased to work wiringpi:
[code]majordomus@pipla4 ~ $ gpio readall
Oops: Unable to determine board revision from /proc/cpuinfo
-> No "Hardware" line
-> You'd best google the error to find out why.[/code]
And the "Hardware" line is gone from the /proc/cpuinfo indeed.
[code]majordomus@pipla4 ~ $ uname -a
Linux pipla4 6.1.61-1-rpi-ARCH #1 SMP PREEMPT Thu Nov 2 12:51:39 MDT 2023 aarch64 GNU/Linux[/code]
[code]/dev/gpio*[/code] as expected by python-rpi-gpio doesn't exist neither.
[code]/sys/class/gpio/[/code] however is still here.
Cheers.
