Hi,
I’m starting upgrading my custom jetson-tx2 project from warrior to zeus (or hopefully dunfell). My current project generates payload files that supports only single board revision and I think that prevents upgrading to newer yocto project. Is it possible to build zeus or dunfell project such as they are compatible with my warrior project.
Hi @hoostol I’m not sure what your issue is. Did you try to do an update? Do you have error logs? It’s possible that you will need a state script or something to bootstrap between major releases but it is definitely feasible to do so.
Drew
Thanks for your answer
my issue is that after updating my board refuses to boot.

Hi @hoostol that is indeed strange. You get no further output? I would expect at least an error mounting the root filesystems. But perhaps the bootconsole [uart8250] disabled is interfering with that.
@lluiscampos are there any known issues updating from warrior to newer?
@dwalkes @madisox any thing in the Tegra BSP that could cause this?
@hoostol @lluiscampos
Due to partition changes across L4T/Jetpack releases, mender upgrading (or anything other than tegraflashing) between yocto branches is currently not supported. Nvidia has some changes they are introducing to support this with L4T r32.6 however there will be some work to do in order to support with mender or any other meta-tegra based update mechanim. Nvidia is offering early access to developers with an NDA for anyone who wants to help implement support for meta-tegra based distributions.
You can see some notes about this in our March OE4T meeting at OE4T Meeting Notes March 2021 and this will likely be a topic discussed there going forward. If you are interested I suggest watching Monthly Meetings · Discussion #515 · OE4T/meta-tegra · GitHub for updates.
As far as the console output goes, I don’t see console=ttyS0,115200 in the kernel command line, and from this at the end of the excerpt:
[ 0.014095] console [tty0] enabled
I’d say any further kernel output is being directed to the graphical console. If you need serial console output, you should check on the setting of KERNEL_ARGS in your custom build setup.
Thank you for the clarification.
If I understand correctly, I can’t upgrade my warrior board to zeus or dunfell without tegra flashing.
And just to be sure, newer Jetpacks are incompatible with warrior branch due to the partition layout changes (zeus or dunfell won’t work with the older (warrior) partition layout).

I think that’s true as a general statement. I’ve got some history of the changes across different products/revisions in my notes at Mender Tegra - Nvidia Jetson Flash Layout - Shared Publicly - Google Sheets in case that’s useful. If you are using uboot on TX2 (and I suspect you are because I don’t think support for cboot came in until after warrior) I know the uboot partition has moved around. There are probably others which have moved around too or have been resized in different ways. @madisox has a commit in the massive zeus refactor he did at RFC: extend support to all Jetsons by madisongh · Pull Request #10 · Trellis-Logic/meta-mender-community · GitHub which attempts to support migrating uboot variables across updates and which isn’t fully tested but might be a good place to start if you want to try supporting this - see RFC: extend support to all Jetsons by madisongh · Pull Request #10 · Trellis-Logic/meta-mender-community · GitHub.
I’ve opened Mender upgrades across L4T releases (and yocto branches) are not currently supported · Issue #14 · OE4T/meta-mender-community · GitHub as a place to track this since this is linked from all board integration pages.
