However, regarding Cédric's log above, a reboot is expected on the first
boot of a fresh image when there's valid VPD available. For the first
boot of a fresh image we configure the kernel with a minimal devicetree
that allows us to read the VPD data. This determines the system we're
actually on and configures an appropriate devicetree for subsequent
boots. We then reboot to pick up the new devicetree.

Yes. Then, the behavior looks correct under QEMU :

  https://www.kaod.org/qemu/aspeed/rainier/rainer.log

Here are the services which still have with some issues :

* clear-once.service                loaded failed failed Clear one time boot overrides * ncsi-linkspeed@eth0.service       loaded failed failed          Set eth0 gigabit link speed * ncsi-linkspeed@eth1.service       loaded failed failed          Set eth1 gigabit link speed * obmc-flash-bios-init.service      loaded failed failed Setup Host FW directories * system-vpd.service                loaded failed failed System VPD Collection * trace-enable.service              loaded failed failed Enable Linux trace events in the boot loader

On my system system-vpd.service was active. I couldn't run your build on my development machine.

That's how I run it :

  qemu-system-arm -M rainier-bmc -net user -drive file=./mmc-p10bmc.qcow2,format=qcow2,if=sd,id=sd2,index=2 -nographic -snapshot -serial mon:stdio

You will need to use my branch to have emmc support.
ok, Thanks you!

Thanks,

C.
