Subject[BUG] wrong pinning definition or uart_c in pinctrl-meson-gxbb.c
Date
Hi i tried to use uart_C of the the odroid-c2.

I enabled it int the dts file. During boot it crashed when the
the sdcard slot is addressd.

After long search in the net i found this:

https://forum.odroid.com/viewtopic.php?f=139&t=25371&p=194370&hilit=uart_C#p177856


After changing the pin definitios accordingly erverything works.

Uart_c is functioning and sdcard ist working.

Patch attached

Bye Otto
