Hi, I wish to set APP and APP_b partitions with different sizes. APP will be the operational partition. APP_b will be a backup/rescue partition with slim kernel and smaller simpler rootfs. I’ve done this successfully on the Orin NX with both partitions in the external NVMe. Now I wish to do the…

You can just generate two different system.img with --no-flash for that purpose. Please do it yourself.

It’s just how large the system image will be, not how large the partition is.

[image] bsp_dev: APP will be the operational partition. APP_b will be a backup/rescue partition with slim kernel and smaller simpler rootfs. I’ve done this successfully on the Orin NX with both partitions in the external NVMe. Now I wish to do the same with the AGX Orin and both partitions on…

flashed twice. first without -k flag (creates both APP and APP_b rootfs) second with -k APP_b (modify only APP_b rootfs)

Is it possible to flash “regularly” , modify the partitions sizes with gparted, backup whole partitions (with modified sizes) with backup_restore tool and then flash it again in future use and it will keep the modified partitions sizes?

I think YES, but you would like to be careful when adjusting the partition size.

I tried using the tool (generate backup imgae) but it failed. this is the log: backup.log (91.7 KB)

The backup tool works but now I left with last problem: If I flash with A/B enabled and then resize partitions sizes with gparted then I get fragmentation because I reduced partition APP size and got free space between APP and APP_b partitions. The only way to overcome this is to move APP_b partit…

[image] bsp_dev: The only way to overcome this is to move APP_b partition but then the system won’t boot (I get a warning message from gparted) What does move mean here? I’m not sure if this will work, but you can give it a try: At first, you don’t enable ROOTFS_AB, and you flash the comple…
