Tty UART access

General

I’m trying to install picocom to access UART devices. Bluefin seems to be having trouble with the dialout group. If a use usermod to add my user to the dialout group then the gshadow file gets updates but not the group file.

Any ideas?

You need to copy dialout group from /usr/lib/groups to /etc/groups. Then add your user to dialout.

Thanks. I have not manually edited the groups file before; surprised “groupadd” didn’t work. But whatever works is good for me.
