Hi
I used the command as @tokurz suggested to me and it gives
tail: cannot open ‘/var/log/syslog’ for reading: No such file or directory tail: no files remaining
I also tried as @ogra suggest to stop the node-red service and access as root with “sudo su” and restarted again the service with “snap start node-red” and the terminal gave to me “Started.”
I also changed the permissions of the " /dev/gpiochip* " using the command
chmod 775 /dev/gpiochip*
At the end the problem still persist and nothing unfortunately has changed. The GPIO is still not available and it is still grey in Nodered.
What do you suggest me to do?
Thanks Matt
