What’s the difference between the dtbo file in the kernel/dtb on BSP and the dtbo file in /boot/ on Jetson Orin NX?

Hello, I have a question. I’m a beginner, and I hope you can tell me specifically.
What’s the difference between the dtbo file in the kernel/dtb on BSP and the dtbo file in /boot/ on Jetson Orin NX?
I thought the dtb and dtbo files in kernel/dtb went under /boot/ in Jetson Orin NX when flash and applied when booting.

When I modified the dtsi file and built it through the “make dtb” command and copied it to kernel/dtb/ in the BSP folder, I checked that the built dtb contained the modification value.
However, when I flash to Jetson Orin NX and decompiled the same dtb below /boot/, the BSP did not include any modifications.

The weird thing here is that it works with the modifications. It hasn’t changed in the dtb file, but I don’t understand that it works. Is there anything I missed?

Dtbo will be handled by UEFI by default. Thus, it got flashed to UEFI device tree partition but not the rootfs directly.

Those you saw under /boot is rootfs.
