swupdate cannot find tegra234-p3737-0000+p3701-0000-nv.dtb image file L4T 36.3.0

[Bmkool]

Hello,

I am attempting to build the swupdate-image-tegra for the AGX Orin devkit on L4T 36.3.0. I am running into this error:

ERROR: swupdate-image-tegra-1.0-r0 do_swuimage: swupdate cannot find tegra234-p3737-0000+p3701-0000-nv.dtb image file

Looks like dtb's are located under the devicetree/ subfolder in the deploy directory starting with L4T 36.3.0.

I am also bumping into this problem. I have solved it by this patch in meta-swupdate:

         else:  # Allow also complete entries like "image.ext4.gz" in SWUPDATE_IMAGES

But I am not sure this is the correct solution.

Another option is to make a bbappend file and re-implement the swupdate_add_artifacts(..) function.

I've used ${DEPLOY_DIR_IMAGE}/devicetree/${DTBFILE} instead of ${DTBFILE} in swupdate-image-tegra.bb and it worked the problem here is that swupdate-image-tegra doesn't cover all the cases. So in t234 machine the DTBs are placed in devicetree directory in depoly directory.

Sorry I'm just seeing this thread now. I suspect this was already handled with https://github.com/OE4T/tegra-demo-distro/pull/305/commits/4e1cdca9936bad099db330ca5126ca4244bfc970 in https://github.com/OE4T/tegra-demo-distro/pull/305 and this just needs a backport to scarthgap.

Verified build succeeds with https://github.com/OE4T/tegra-demo-distro/pull/309 - if someone with jetson-agx-orin-devkit could help test it I would appreciate, I don't have access to that platform.

Resolved with https://github.com/OE4T/tegra-demo-distro/pull/309 based on element discussion

Thanks, verified to work for the jetson-orin-nano-devkit-nvme.
