How to include generated dtb

[NavSriv]

Hi,
I am working on J4011 Seeed Studio Industrial board (8GB). I am using scarthgap for poky, meta-tegra and meta-openembedded and my local.conf has below configuration -

MACHINE ??= "p3768-0000-p3767-0001"
TNSPEC_BOOTDEV:p3768-0000-p3767-0001 = "nvme0n1p1"
KERNEL_DEVICETREE ?= "tegra234-p3768-0000+p3767-0001.dtb"

I created a kernel patch against meta-tegra comparing Seeed github, but I realised it hasn't made changes to dts file. Also, I assume nvidia-kernel-oot and nvidia-kernel-oot-dtb deal with dtbs based on meta-tegra default kernel configs.

I can find dtbs available in dtb link of Seeed. How should I get Seeed dtb into the rootfs? Should I create a .bb to copy right dtb file to /boot/dtb/ (assuming /boot/dtb is the right path)? Should I stop compilation of nvidia-kernel-oot?

Custom board isn't working well for second LAN port so I assume changing dtb should fix the issue.

Take a look at this commit in our demo distro for an example of how to do this. The example builds the device tree from sources, but if you have only prebuilt .dtb files, you could omit the inherit devicetree and just install and deploy the prebuilt files directly, to the same locations that that bbclass uses.
