Defective Omega 2+? Hundreds of SQUASHFS Errors

Leif Bloomquist

Ugh! Fortunately I ordered two Omega 2+'s. The first one works great, the second one, not so much.

Briefly:

Setup wizard worked OK, though some steps seemed to take a lot longer than the first one
After upgrading, the Omega LED would turn on briefly, then turn off. No signs of life.
I managed to get the serial console working, and found the "hold the reset button" trick to get into U-Boot.
Put the latest firmware on a USB stick as omega2.bin, used the recovery menu option, and was back in action...somewhat.
After redoing the setup wizard with serial console running, I get the following and the Omega2 is inaccessible.

Partial log attached, due to the 32767 char post limit
