Subject: Re: [BUG] wrong pinning definition or uart_c in pinctrl-meson-gxbb.c
Date: Tue, 10 Sep 2019 18:01:41 +0200
Message-ID: <1cc32a18-464d-5531-7a1c-084390e2ecb1@gmx.net> (raw)

Hi i tried to use the uart_C of the the odroid-c2.

I enabled it in the dts file. During boot it crashed when the
the sdcard slot is addressed.

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 definitions accordingly erverything works.
Uart_c is functioning and sdcard ist working.
