AGX bootloop after powercut during update process, attempts to reflash unsuccessful

Robotics & Edge Computing Jetson & Embedded Systems Jetson AGX Xavier
1

A powercut occured as I was trying to upgrade my AGX Xavier from Ubuntu 18.04 to 20.04. While I understand that this process is not officially supported by the jetpack sdk, I have attempted the same process on a Xavier NX many times with success. As a result of the powercut during the update process, however, as I attempted to restart my AGX afterwards, it enters a bootloop instead and fails to boot up properly. I have then attempted to use the same host machine that I used originally to flash and install the jetpack SDK to reflash the jetson OS on the AGX. I have retried this process multiple times, ensuring I put the AGX into recovery mode, with lsusb displaying

“Bus 001 Device 003: ID 0955:7019 NVidia Corp.”

as expected, and with both the SDK manager and through terminal with

cd /home/user/nvidia/nvidia_sdk/JetPack_4.5.1_Linux_JETSON_AGX_XAVIER/Linux_for_Tegra
sudo ./flash.sh jetson-xavier mmcblk0p1

both methods returning with the following errors on all my many attempts all day:

16:03:36 INFO: Flash Jetson AGX Xavier 16GB/32GB - flash: Error: probing the target board failed.
16:03:36 INFO: Flash Jetson AGX Xavier 16GB/32GB - flash: Make sure the target board is connected through
16:03:36 ERROR: Flash Jetson AGX Xavier 16GB/32GB - flash: command terminated with error

and

###############################################################################

###############################################################################
Error: probing the target board failed.
       Make sure the target board is connected through 
       USB port and is in recovery mode.

Please adivse, I would like to simply reflash the device and reinstall everything from step 0.

Do you have other xavier device that can validate the setup of your host is fine? If only this xavier that cannot be detected in recovery mode, please RMA this device.

4

SDK and lsusb detects both this device and my other Xavier NX just fine, and I do not wish to flash my other Xavier NX as I have it in use for other developmental operations. In that case how should I apply for an RMA on this device? Thanks.

5

Just another check. Do you have other ubuntu host that can do the flash work?

6

Unfortunately I only have this device I’m using that is running ubuntu through dual-boot with Windows 10.

The RMA process is listed here.

Following the RMA process, the live chat option is currently unavailable, any idea when this feature will be available again or alternatively what should I do?

Hi 0.zer0thefool,

Is this still not working? Can you try again?

Thanks

It’s been down every time I’ve checked since, and I have tried ringing the phone number of your local office in Hong Kong, also to no avail. Please advice what to do now.
