How to use gtk & device file together

stomo.1 · ‎2022-12-09

bord: STM32MP157-EV1

I want the LCD to display messages received by UART communication.

However, when I run GTK with the command below, I get an error because I can't access the device file.

su -l weston -c "/usr/local/xxxx"

What should I do?
