BPI-R4 wont boot up fully

Tried using the uart 1 etc and all I get is garbled junk with that

Other uart has to be configured to use as debug port and even when setting speed in cmdline it was still 9600 in my basic tests

Afaik @rmandrad did some further tests with uart1/2 here but also needs change in pinctrl and dts

Ah I see, well that’s out of the question then because I can’t boot off sd card, can only press reset and enter recovery mode
