Thanks for the info. I'm still not seing why that wouldn't work.

As the machine seems to have a serial port, can you please replace
'earlycon' with 'earlyprintk=ttyS0,115200' on the command line and see
whether that gives some output. I'm not sure that the current 'earlycon'
has the same effect.

Thanks,
