Hi All:
I want to create an OTA package while retaining the /nat_env directory of the jp5.1.2 device environment, and add a new partition nvme0n1p16, and copy the original nat_env content to the nav_env (nvme0n1p16) of the new partition. The situation is as follows.How can I achieve it?

It seems the duplicate topic as How to keep the original system directory and files in OTA - Jetson & Embedded Systems / Jetson Orin NX - NVIDIA Developer Forums, I’ve replied you there.

Do you mean this custom partition is not included in your JP5.1.2 before update?
It seems not the expected operation to me that “using OTA update to create custom partition”.

I’ve noticed that the rootfs in your JP5.1.2 is 952.4GB, but it is 64GB in your JP6.2.
It cannot be achieved by image-based OTA update since OTA update is not used to repartition the disk. It is used to update the data in the partition and the firmwares.
