Rock 5B fails to boot

#1

I tried all the official images, the output is always the same on UART:

error

#2

can you provide exact command that you use to connect with UART?

#3 
      $ sudo minicom -D /dev/ttyUSB0

Then I configure minicom for 1500000 baudrate 8-N-1 no hardware flow control
But the UART is working fine, otherwise I would not see the log output

#4

Is this likely to be a hardware problem?
I did not manage to fix it, no matter what image I flash.

#5

This does look like a memory training failure, which usually means hardware problem. Please contact Allnet again to proceed with your RMA.

#6

Hi,

After RMA we got what seems the same unit reworked.
Now the unit boots to a login on Radxa debian official image, but the HDMI doesn’t work.
Please let us know how to proceed.
This is the serial output (binary dump follows but I removed it):
