    Instead, maybe check this. Nothing says you have to have root rights. // Using the setuid bit still makes the script run as root (except scripts cannot use setuid). I suggest you read up a little on Linux and chmod and whatnot.

  • You should never ever set the SUID bit on a script As Daniel pointed out you can allow your normal user to access GPIO just fine.

  • Thanks, to both of you - actually I already found the question but I didn't get it to work. I will take a closer look. And even though setting the suid bit is not recommended, I am interested what I missed. The owner is root, the executable and suid bit are set and still when I run my python gpio script I get the dev/mem permission denied error. Also tried this with a bash script and whoami -> echoes pi. Its a bit frustrating, every solution I found is either not working or not recommended...

  • I updated my question, seems like the package I am using doesn't supports /dev/gpiomem
