[Sandeep]: May be this is old and not used anymore. I will obsolete this
recipe after check with internal team if no one is using if for any
specific purpose.
But we do not have the "shutdown_scope".

Hi Ulf,
Reboot and other PM features is implemented in Firmware driver. For
more details refer wiki page
https://xilinx-wiki.atlassian.net/wiki/spaces/A/pages/18842232/Zynq+UltraScale+MPSoC+Power+Management+-+Linux+Kernel
May be you are missing hellopm
https://github.com/Xilinx/meta-petalinux/tree/rel-v2022.2/recipes-examples/hellopm
app in your image. Can you add hellopm and try with this?
IMAGE_INSTALL:append = "\
hellopm \
"
Thanks,
Sandeep

We have a linux Zynqmp system based on Petalinux rev2022.1/systemd
We can halt the system, but if we try to reboot, systemd shuts down
and it does not reboot. We would expect the chip to reset, and start
from boot.bin.
If we try to reset the chip in U-Boot, there is no problem.
Does reboot depend on any connection on the PCB?
Best Regards
Ulf Samuelsson
