OK, that does help. IMO the documentation could be improved by placing that info panel after the heading rather than its current placement (or linking both repositories in the snippet below), because it is off the bottom of the screen for a typical 1920x1080 resolution and the immediate sentence I saw and went to while skimming for a new repo URL was
Toradex provides source files of Device Trees and Device Tree Overlays for the add-on products available in the webshop. For information about these overlays, see the Toradex Device Tree Overlays repository on Github and …
Hello @bw908 ,
thanks for your feedback. We’ll pass your suggestion to the development webpage team.
Did the answer from @jeremias.tx solve your issue? If so, please mark his answer as a solution.
I am still having problems getting the system to boot 6.2.x with any sort of non-builtin devicetree.
I have checked out the kernel and devicetree repos per the article and am attempting to build the OS with the reference verdin-nonwifi-dev.dts file and no filesystem customizations of any kind. My tcbuild.yaml has this:
easy-installer:
local: torizon-core-docker-verdin-imx8mp-Tezi_6.2.0+build.2.tar
[snip]
device-tree:
# >> Directories where to look for include files.
include-dirs:
- linux/include/
# >> Custom device tree source:
custom: my_dts/imx8mp-verdin-nonwifi-dev.dts
(The my_dts folder does contain the additional imx8mp-verdin dtsi files required that are not in include)
However, it fails to boot. The serial port shows the following in the output. The RCU stall message repeats several times before the system eventually watchdogs and resets 3 times before rolling back to the previous 6.2 build (which was made with the customization section completely commented out).
device_remove: Device 'mmc@30b60000.blk' failed to remove, but children are gone

The imx8mp-verdin-nonwifi-dev.dts device tree that you’re applying it’s unmodified correct? Also did you copy it from the same Linux source that you just cloned?
Also, here is a successful boot (after rollback) to a deploy without the ‘customization’ section:
The missing hardware errors are expected, this is a custom carrier board but there is nothing incompatible with the dev board dts.

Yes, and to confirm I just tried it by using the same path you did, which is in the kernel tree. Same result. Here is the full serial output, perhaps you see something I am missing.

Are you suggesting it won’t be possible to field update devices to 6.x that were originally flashed with 5.x? That’d be somewhat concerning…
You can but not with just TorizonCore Builder. Upgrading between major software versions is not a simple process as there are a lot of differences between two major versions like 5.X and 6.X. Notably you’ll need to update the bootloader as well. More details on this process are specified on this page: Bootloader Updates in Torizon OS | Toradex Developer Center
Please read this page carefully since updating the bootloader is not a trivial process as you can imagine. Support for offline bootloader updates is yet to come.
