hello muralikrishnan.t,
it’s suggest to update l4t_generate_ota_package.sh and ota_board_specs.conf for customize board to create OTA payloads.
please see-also Topic 332980 for an example.
besides.. you’ll need to generate OTA payload with ROOTFS_AB=1 and ROOTFS_ENC=1 since you’ve enable root file system redundancy and disk encryption.
here’s an example for OTA payload creation.
$ export BASE_BSP=~/nvidia_sdk/JetPack_6.0_Linux_JETSON_ORIN_NX_TARGETS/Linux_for_Tegra
$ export TARGET_BSP=~/nvidia_sdk/JetPack_6.2_Linux_JETSON_ORIN_NX_TARGETS/Linux_for_Tegra
$ sudo ROOTFS_AB=1 ROOTFS_ENC=1 -E ./tools/ota_tools/version_upgrade/l4t_generate_ota_package.sh --external-device nvme0n1 -i ./sym2_t234.key --uefi-keys ./uefi_keys/uefi_keys.conf --rootfs-uuid 2ff299c5-0b33-46ce-8ba7-136ecf882384 --rootfs-b-uuid 7da5fc07-9ca4-4cd3-94b9-e08b2c479ada --uda-uuid 8e109028-09f6-4c37-abee-af196dbea12a jetson-orin-nano-devkit R36-4
