Flashing with A/B Encrypted Partitions

[brian178]

I have a working sample with LUKS FDE that uses flash_l4t_t234_nvme_rootfs_enc.xml to configure that partitions and flash the jetson.

Can i just replace this with flash_l4t_t234_nvme_rootfs_ab_enc.xmlin my flash steps or are there other specific procedures that need to be accounted for when doing an A/B flash?

Hi brian178,

Are you using the devkit or custom board for Orin Nano?
What’s your Jetpack version in use?

Yes, you can replace the flash_l4t_t234_nvme_rootfs_enc.xml with flash_l4t_t234_nvme_rootfs_ab_enc.xml as partition layout file for external NVMe SSD if you want to enable redundant rootfs.
