4. Boot Instructions
====================

You must load the DTB (device tree blob) into the target's memory
prior to booting the kernel Image. The DTB file can be found in the export
directory after building a project, or you can generate it manually with the
following commands:

        # bitbake -c devshell virtual/kernel
        # make zynqmp-<Board Name>.dtb
---

Correct command is :

make zynqmp-<Board Name>.dtb

Also it would be helpful to mention where we can retrieve the different supported <Board Name> :
--> ls arch/arm64/boot/dts/xilinx/
