Why can't I compile the device tree?

When I use the Jetson Orin Nano DevKit with version 36.4.3, I want to use /ivc-echo-task.c, so I modified the file Linux_for_Tegra/source/hardware/nvidia/t23x/nv-public/nv-platform/tegra234-p3768-0000+p3767-xxxx-nv-common.dtsi. However, I don’t quite understand the following two steps:

  1. Compile the device tree and copy the dtb file to the Linux_for_Tegra/dtb/ directory.

  2. Rebuild the device tree and reflash the board by referencing the instructions in the “Building the Kernel” section of the Linux Developer Guide.

I am not sure how to compile the device tree. What should I do?

Currently, I have already installed the toolchain. However, after running the following commands:

export CROSS_COMPILE=$HOME/l4t-gcc/aarch64--glibc--stable-2022.08-1/bin/aarch64-buildroot-linux-gnu-
export KERNEL_HEADERS=$PWD/kernel/kernel-jammy-src
make dtbs

I encountered the following error:
