JetPack 6.0 custom board flash fails - reading board information fails

[naxty]

Hello,
we have designed a custom jetson orin nano board 8GB very similar to the dev board. We were quite happy with it and could successfully flash it up to Jetson Linux 35.5.x / JetPack 5.1.3. Due to some dependencies we want to upgrade to JetPack 6.0. However, every time we are trying to flash with Ubuntu 20 / 22 Jetpack 6 from two different computers it fails to flash with the information reading board info failed. However, it works when we just flash it with JetPack 5.1.3. My colleague is doing the flashing and then sends me unit to develop them. He flashes these with nvsdkmanager and has no problem with JetPack 5.1.3. With JetPack 6 he is also unsuccessful. Flashing the devboard 4GB / 8 GB works fine with JetPack 6. We have no idea what we can do to fix this. What is also strange that when he flashed them with his computer I can’t reflash them with my computer. What’s the reason for this?

I also tried to flash it with sudo SKIP_EEPROM_CHECK=1 BOARDID=3767 BOARDSKU=0005 ./flash.sh jetson-orin-nano-devkit external but then the flashing just hangs. Even run with initrd but it also doesn’t flash the board in the end Flashing Support — NVIDIA Jetson Linux Developer Guide 1 documentation

Is anyone having similar issue? What information can I provide to fix this?

Yes, sorry for not positing it in advance. It was a pretty dumb error message that said that reading board information failed. After having tried a couple of different things and failed on the process I tried something else.

Basically, I have found the solution by formatting the SSD to ext4. Here is what I did:

sudo parted /dev/sdX
mklabel gpt
mkpart primary ext4 0% 100%
quit
sudo mkfs.ext4 /dev/sdX1

You don’t know how happy I am that I finally found a solution. I wasn’t able to flash our production boards for months and finally I could flash it. I still can’t believe that it was a simple solution. Maybe, this information is written down in the documentation. Posting this to help others.

Thanks!
