Jetson Nano not booting

I have followed the instruction on the Jetson Nano “getting started” page to flash a UHS-1 SD card. However, the nano is not booting. I am using the DC barrel port for power and have tried two different cards.

It appears from the serial log that things get lost during the handoff from the bootloader to kernel.

Any ideas of what is going wrong?

Looks like I will be returning my board for a refund.
