how to compile device tree blobs?

Hi, jetsonhacks!
I find that the makeKernel.sh would not make dtbs.
If we want to compile device tree and update it,

would adding "make dtbs" in the makeKernel.sh and "sudo cp /arch/arm64/boot/dts/xxxxx.dtb /boot/" in copyKernel.sh files work this out?

The compiled device tree files are stored on a separate partition on the Jetson eMMC, therefore the method you suggest does not work.

You mention that we need to compile the device tree separately. How do we do this?

The easiest way is to follow the NVIDIA directions to use a device tree compiler and flash the device tree from a host PC.
