Steps to Reproduce

1. Build project

$ setup.sh --machines xilinx-zynqmp --templates=feature/kexec,feature/kdump --dl-layers --all-layers --accept-eula=yes
$ source environment-setup-x86_64-wrlinuxsdk-linux 
$ source oe-init-build-env
$ vi conf/local.conf # set BB_NO_NETWORK as '0'
$ cat << _EOF >> conf/local.conf
DISTRO ?= "wrlinux-graphics"
PREFERRED_PROVIDER_virtual/mesa:xilinx-zynqmp = "mesa-gl"
PREFERRED_PROVIDER_virtual/libgl:xilinx-zynqmp = "mesa-gl"
PREFERRED_PROVIDER_virtual/libgles1:xilinx-zynqmp = "libmali-xlnx"
PREFERRED_PROVIDER_virtual/libgles2:xilinx-zynqmp = "libmali-xlnx"
PREFERRED_PROVIDER_virtual/egl:xilinx-zynqmp = "libmali-xlnx"
WRL_RECIPES:xilinx += "libmali-xlnx"
WRL_RECIPES:xilinx += 'kernel-module-mali'
LICENSE_FLAGS_ACCEPTED += "xilinx"
_EOF
$ bitbake wrlinux-image-std-sato


2. Load images to the ZCU102 board (#29041)

3. Run the following commands

kexec:
root@xilinx-zynqmp:~# cat /proc/cmdline > args
root@xilinx-zynqmp:~# cp /boot/Image /boot/kernel_kexec
root@xilinx-zynqmp:~# kexec -l /boot/kernel_kexec --append="`cat args`"
root@xilinx-zynqmp:~# kexec -e
