Parts of the BUP payload, like the DTB, are specific to a version of the TX2 module you have in your device. Only if a copy in the payload matches the version of your module will nv_update_engine install it.
The version information it uses for matching is in /etc/nv_boot_control.conf on the TNSPEC line. Can you post that here?
Thanks for your help!
Here is the requested output
[2020-06-30 13:57:57] root@jetson-tx2:~# cat /etc/nv_boot_control.conf
[2020-06-30 13:57:59] TNSPEC 3310-D00-1000-F.0-1-0-jetson-tx2-mmcblk0p1

and for what it’s worth I get this when I grep for 3310 in the bl_update_payload (not sure if it’s relevant):
root@jetson-tx2:~# strings /opt/ota_package/bl_update_payload | grep 3310
3310-1000-B00-A
Yes, that’s the problem, then. If you’re using the zeus branch in meta-tegra (based on L4T R32.2.3), BUP payloads built only support a single board revision. The zeus-l4t-r32.3.1 branch builds multi-spec BUP payloads, and it should be including the necessary artifacts for the revision D00 FAB.
We are on the zeus-l4t-r32.3.1 branch, actually. Is there a specific (recent) commit that we need to be aware of?
Is is possible to misconfigure/misuse this feature somehow on our end?
Can I check something in my build to verify the generation of the payload works as expected?
Thanks!
I tried to dig a bit deeper. But to be honst I don’t quite understand how the different bup payloads are getting build and deployed. I see multiple payloads being deployed in the images directory (e.g. u-boot-dtb.bin.bl_only.bup-payload) but they all contain only the 3310-1000-B00-A string.
But the generated generate_bup_payload.sh file looks like this and does contain the paramenters specified in jeston-tx2.conf:
#!/bin/bash
rm -rf signed multi_signed rollback.bin payloads_t18x

Should this build result in one BUP package that will work on all specified board revisions? Or do we need to explicitly set this information somewhere?
Should this build result in one BUP package that will work on all specified board revisions?
It should, yes, once it’s done. You can verify this with the BUP_generator.py script, which you can extract from the L4T BSP (in the Linux_for_Tegra/bootloader directory).

Hi @madisox,
I have the feeling I am missing something very basic in my configuration.
This is the output for the same file on my build. There are no devicetrees included:

Check the log file for the u-boot-bup-payload do_deploy task, which should be at $BUILDDIR/tmp/work/jetson_tx2-poky-linux/u-boot-bup-payload/1.0/temp/log.do_deploy (or something similar, depending on your distro configuration). I have seen cases where the BUP generator script encounters (and logs) errors but doesn’t fail out the execution of the task. That could be happening here.
Ok, some of the sections look suspicious. It seems the script can’t find relevant files. Do I interpret that correctly? Is there a dependency missing?

Thanks a lot for your help on this! I really appreciate it!
Yep, that’s the problem. I think this is due to some recent commits in meta-tegra that need some corresponding changes in the meta-mender-community/meta-mender-tegra layer.
I have some changes on a branch in my fork of that repository that should fix this. In particular, this commit.
Awesome! Your patches fixed it for me, the payload contains the devicetrees now!
Many thanks again for your quick help with this issue!
@mirzak, do you have a timeframe when those patches will make it into mender?
I thought @dwalkes had already picked up those patches to upstream to meta-mender-community… I’ll work with him to get them there.
I can confirm that these patches enabled me to update the dtb using nv_update_engine.
There was a big update merged from @dwalkes (link) but I can not see that the mentioned change-set was part of that PR.
@madisox looks like it didn’t make it into https://github.com/mendersoftware/meta-mender-community/pull/147/commits. I just opened a PR here with the changes that didn’t make it in.
Was it intentionally targeting your own fork of meta-mender-community?
Was it intentionally targeting your own fork of meta-mender-community?
Yes, I wanted to test with repo tool and the latest zeus branch first myself, then will open a PR to meta-mender-community, hopefully tonight.
See https://github.com/mendersoftware/meta-mender-community/pull/159 for PR to meta-mender-community.
