Upgrade from Jetpack 4.6.1 to dev preview 5

Hey,

Maybe a stupid or too obvious question but i received my Xavier NX based system (Advantech mic-710ailx to be more specific) preinstalled with Jetpack 4.6.1. I need to upgrade to 5 in order to run my custom software on ubuntu 20.04.

I have followed the getting started steps to create microSD card with Jetpack 5 flashed on it. What next? Even if i install physically the SD card to device the old system is still boots up. I am not too familiar with Linux based systems. Should i somehow select boot priority to start installation from image?

I have tried to search for tutorials and topics with no success.

Thanks in advance

I can’t answer, but is it correct that your NX is a dev kit (using SD card)? If so, then boot content is on the QSPI memory, which is part of the board itself, and not on the SD card/rootfs. You would have to flash the Jetson itself with JetPack/SDK Manager to get the correct boot content. However, I don’t know if the DP 5 supports the NX dev kit or not.
