OTA JP6.2.2 to JP6.2.2 support question

Hello!,

I have some OTA questions related to the JP6.2.2 release:

From the documentation here: Software Packages and the Update Mechanism — NVIDIA Jetson Linux Developer Guide

It seems OTA supports JP6.2.1 to JP6.2.2 updates but JP6.2.2 is not listed, in other words JP6.2.2 to JP6.2.2 (R36-5) are not supported according to the documentation:

Is this case supported? Other section on the documentation mentions that same BSP release supports OTA updated to the same BSP release, which I have validated in previous releases.

How can I run OTA updates in a system with ROOTFS_AB enabled running R36-4 in both partitions?

My understanding to get both partitions on R36-5 would be:
-Generate the OTA payload for R36-4 to R36-5 which is in the supported list
-For the second partition, we would need to generate a R36-5 to R36-5 OTA payload but this case is not listed, so how could this second partition be updated to the latest JetPack version.

For testing purposes I prepared a JetPack 6.2.2 environment and tried to generate the R36-5 to R36-5 OTA payload and it failed:

fallasg@u8d4d1779faab5e:~/jetpack/JetPack_6.2.2_Linux_JETSON_AGX_ORIN_TARGETS/Linux_for_Tegra$ sudo -E ./tools/ota_tools/version_upgrade/l4t_generate_ota_package.sh  jetson-agx-orin-devkit  R36-5

		<bsp version>: the version of the base BSP. Supported versions: R35-5, R35-6, R36-3, R36-4.

This is the error for not supported version:
Target board(JETSON_AGX_ORIN_DEVKIT) and base version(R36_5) is not supported

I was checking the code on the OTA tools, I was wondering if there are missing code on the ota_board_speccs.conf file, example section below:

JETSON_AGX_ORIN_DEVKIT_R36_4_ALIAS="jetson_agx_orin_devkit_ota_emmc_r35_r36_spec"

This is the board description, so my point was if there is a missing reference to JETSON_AGX_ORIN_DEVKIT_R36_5_ALIAS="jetson_agx_orin_devkit_ota_emmc_r35_r36_spec"

to properly enable the JP6.2.2 to JP6.2.2 OTA update support.

Any provided information is appreciated to understand how to get the system on both partitions to R36-5.

Thanks.

[EDIT]

hello greivin.fallas,

the current OTA Tools does not support for R36.5 Image-based OTA update. it’s still under investigation.
please visit the jetson-linux-r365 for the updated OTA package, OTA Tools r36.5 (updated on 5/22).
