Please share full dmesg.

#4

@WayneWWW how should I do that? I am unable to get past that error screen. when i change back to microUSB, dmesg doesnt show that error. /var/log/kern.log doesnt log those error as well

#5

Use the uart console.

#6

unfortunately i do not have access to those wires

#7

Then get such wire. Otherwise this issue won’t proceed.

#8

exactly the same as this Serial Log here

#9

Is this still an issue to support? Any result can be shared? Thanks

#10

I jacked up the step down converter to 5.7V+ and the error stopped.
