Currently I am using the orin nano 8GB board. I need to compile my own device tree.
I am trying to find the exact device tree that is used for this device from the linux kernel source but I was unable to find it as per this following information.

root@orin-nano:~# cat /proc/device-tree/model
NVIDIA Jetson Orin Nano Developer Kit
root@orin-nano:~#
root@orin-nano:~# cat /proc/device-tree/compatible
nvidia,p3768-0000+p3767-0005nvidia, nvidia,tegra234
root@orin-nano:~#

Can anyone help me to find the device tree and modify it for my custom board ?.
Even in the dmesg logs I am unable to find the device tree used and in the linux kernel source tree I found only the folllowing

tegra234-sim-vdk.dts
tegra234-p3737-0000+p3701-0000.dts
tegra234-p3737-0000.dtsi
tegra234-p3701-0000.dtsi
tegra234.dtsi

Thanks in advance

Hi mallempati.rajesh,

Are you using the devkit or custom board for Orin Nano?
What’s the Jetpack version in use?

Please run the following command and share the results.

$ cat /etc/nv_boot_control.conf
$ cat /boot/extlinux/extlinux.conf
$ ls -l /boot/dtb

Actually, you can also check the full flash log to know which DTB is used for your board.
