Hi, I am trying to ran a meta-qcom build on a spare OnePlus-3 device. I took latest version of meta-qcom as well as a recent version of poky:master branch. From the generated artifacts I try to boot the device via:

$ fastboot boot boot-apq8096-db820c-qcom-armv8a.img
Sending 'boot.img' (8040 KB)                       OKAY [  0.280s]
Booting                                            FAILED (remote: 'dtb not found')
fastboot: error: Command failed

So you have any hint why a dtb might not be landed in the img file? The overall Yocto process though complained (warnings) about missing adreno and furth qcom firmware but succeeded without error.

I'd guess that you are trying to boot the apq8096-db820c image (which uses the apq8096-db820c.dtb) on a phone which has strict DTB requirements. Please open conf/machine/qcom-armv8a.conf, add qcom/msm8996-oneplus3.dtb to the KERNEL_DEVICETREE list, build the image and boot using boot-msm8996-oneplus3-qcom-armv8a.img. Note, there are two different models: OnePlus 3 and 3T, please choose the correct DTB.

Thanks a lot for the hint! Yet this seems not to work or to not work entirely. I tried with the specific oneplus3 dtb (after confirming that this really is a non-3T variant) and am getting the exact same output as before.

@cordlandwehr you might need to add and/or fix bootloader properties like qcom,msm-id, qcom-board-id and qcom,pmic-id, check them in the downstream tree.

Another suggestion is to ask this quesiton on the #linux-msm channel on OFTC.
