Troubleshooting • Re: No access to /dev/mem is killing me

$

I now have it running on boot with chmod 777 to /dev/gpiomem in rc.local.
But with that I have no keyboard input. It seems I should be using systemd, but I cannot find anything about running chmod with systemd.
It appears to be running the exec only and not able to run a command line input. I did try leaving the chmod in rc.local with only the python code in systemd, but no luck.

Can anyone help with this?
