Hello, it has been a few months since I used my jetson orin nano. Recently, I wanted to try out a new algorithm, however, when I tried to upgrade the ubuntu system from 20.4 to 22.4, I can’t seem to successfully reboot the system.
After I restart the device, there is a pop up error message : “Oh no! Something has gone wrong. A problem has occurred and the system can’t recover. Please Log out and try again.”
I tried restarting the rebooting, updating and upgrading the system but to no avail. When I logged back in, the system would notify me to reboot the system, but the same error message persisted.
Could anyone give me some suggestions on how I can solve this?
Previously, I have exisiting models in the system, should I uninstall them, if so how do i do that?
Is this the Orin Nano SD card model of developer kit? The answer changes if this is an eMMC model, which would use a third party carrier board. Assuming this is a developer’s kit that uses an SD card, the following applies. For reference, L4T R35.x is Ubuntu 20.04, while L4T R36.x is Ubuntu 22.04 (it just gets that name when it has NVIDIA drivers).
The SD card model of developer kits will have QSPI memory on the module itself, but no eMMC. The boot chain goes on the QSPI, while the o/s itself goes on the SD card. If for some reason the QSPI is using a different major release, then booting to the SD card of the “different” major release will fail. I suspect you need to flash the QSPI.
JetPack/SDK Manager is just a front end to the flash software. You’ll probably want to flash the QSPI and then check if that SD card now works. Look up the most recent L4T release here, and then go to the JetPack/SDK Manager release listed for flashing that: https://developer.nvidia.com/linux-tegra
You should be able to use an Ubuntu 20.04 or 22.04 host PC for flashing that. It won’t be obvious, but you can uncheck different items in the flash or optional content options. After that, try your SD card. If it still fails, then there was a different issue.
