I flashed Orin with ROOTFS_AB=1. There A and B partitions came asymetric and there is no UDA partition:
root@orin:~# gdisk -l /dev/mmcblk0
GPT fdisk (gdisk) version 1.0.5
Partition table scan:
MBR: protective
BSD: not present
APM: not present
GPT: present
Found valid GPT with protective MBR; using GPT.
Disk /dev/mmcblk0: 124321792 sectors, 59.3 GiB
Sector size (logical/physical): 512/512 bytes
Disk identifier (GUID): 202E73F0-83C8-465F-8400-1A008A8C6502
Partition table holds up to 128 entries
Main partition table begins at sector 2 and ends at sector 33
First usable sector is 40, last usable sector is 124321752
Partitions will be aligned on 8-sector boundaries
Total free space is 24 sectors (12.0 KiB)

Is there a way to enable/configure the UDA partition (e.g.shrink APP_b to the size of APP and and add UDA)? I would like to have configuration similar to Xavier, which is:
Number Start (sector) End (sector) Size Code Name

2 29360168 58720295 14.0 GiB 0700 APP_b
