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
?
