Hello with the actuel Pinning definition in  pinctrl-meson-gxbb.c for the uart_c
the system crashes when activated. The seams to be a depency with mmc driver 
for SD cards.
 
according to the comment here: 
https://forum.odroid.com/viewtopic.php?f=137&t=25373#p177855
the seams to be an error in the amlogic datasheets regarding uart_c
 
with the attached patch everything works as it should.
 
Best regards
