Jetson Nano 2GB Dev Kit got bricked after `sudo apt upgrade`(Serial Log Included)

I got the Jetson Nano 2GB, Installed Jetson OS successfully using Etcher and booted fine for the first time. I issued sudo apt update and sudo apt upgrade. After restart, the system does not boot at all. It is stuck at Nividia Logo. I connected serial usb and here is what I get on serial. It’s complaining about ERROR: reserving fdt memory region failed (addr=0 size=0): Here is the full log:

boot_log.txt (17.7 KB)

Here is what I tried with no success:

  1. I re-downloaded and re-installed Jetson OS on different Micro SD cards
  2. I used SDKManager to flash directly but for some reason jetson os flashing gets stuck at 99.80%.
  3. I tried to compile u-boot and used sudo ./flash.sh -k LNX jetson-nano-2gb-devkit internal but for some reason it is not successful and gets stuch at 'boot rom communication` message.

Is this unit bricked? should I RMA it?

`

Can you directly use below setup and command to share log?

Setup:

  1. Monitoring the serial console log on your host.

  2. Run commands: sudo ./flash.sh jetson-nano-2gb-devkit mmcblk0p1

  3. You shall see flash.sh returns one log, we call it host log. And you shall see the serial console print another log, we call it device log.

  4. Please copy both logs and attach them as text file here. We need the full log. So please do not just give my a one line log.

I apologize for the incomplete logs. Here are the full ones:

Hello,

The device log is not “during the flash”. It is already boot into kernel.

What I need is checking if the uart log printed anything when “doing flash”.

It does not output anything doing the flash. Both minicom and screen’s outputs are empty.

Ok, then please RMA this module.
