New contributor, so hopefully this makes it correctly to the thread.

The way I do it:


1)      Modify KERNEL_IMAGETYPE to "vmlinux" in tune-zynqmp.inc

2)      Execute bitbake.

3)      Source <petaLinuxPKGInstall>/settings.sh

4)      Export several variables with separate export statements: LD_LIBRARY_PATH=<petaLinuxPKGInstall>/tools/lib, LM_LICENSE_FILE=<petaLinuxPKGInstall>/etc/license/petalinux.lic, PETALINUX_ARCH_AARCH64=y, and USERNAME=root

5)      Execute: petalinux-gen-fitimage --kernel vmlinux --dtb system.dtb --output image.ub --kernel_compression gzip --kernel_hash crc32 --kernelconfig uImage.config

Note: vmlinux is built in #2, system.dtb is built in #2 as something.dtb, both from the bitbake command, uImage.config (my name) can pulled from #2 as well.  Issue a find command at the build directory "find . -name .config" (if multiple, pick the one from the kernel-build-artifacts location).
