hi
  The software version I use is JetPack 3.0 and the hardware version is TX2.
  I am looking through the help document (Tegra_Linux_Driver_Package_Documents_R27.1).
  Run source_sync.sh -k tegra-l4t-r27.1 download source and patch.
  The directory where the kernel device tree source file is located is hardware/nvidia/platform/t18x/quill/kernel-dts,
  How to compile the kernel device tree file? Is it using a kernel device tree file?
Thanks

Please try dtc (device tree compiler)

https://git.kernel.org/pub/scm/utils/dtc/dtc.git

You can modify “DTB_FILE” field in the config file under Linux_for_Tegra to the dtb file you want to use.

dtc does the actual compile, but if your kernel source is configured correctly, and if environment is set up, you might try the “make dtbs” target for kernel build (adjust with the correct environment if cross compiling).
