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
