Hi guys, We are struggling to understand if and how the device tree gets updated on a Jetson-TX2. A rootfs image created by yocto (“zeus”) does not seem to update the device tree when updating through mender. How can we update the device-tree partition(s)? Thanks!

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 .

Not the same board, but some inspiration: Updating a Raspberry boot partition

So, it requires the dtb to be present in your rootfs.
