Yes

Not applies

Steps to reproduce
-Whenever you send a reboot comand after shooting down, the Odroid C2 never boots up, I need to unplug/plug manually the power suply. (No way to work remotely after a reboot command).
-After plug an screen to the Odroid C2 board and send even locally the reboot, I can see how the OS shut down properly finishing all the tasks, then a black screen and never boots again unles I unplug the board (this never happend with older verions).

Expected behaviour
-A regular restart of the OS.

Actual behaviour
-The board never boots again after a reboot command.

Many thanks for your report.

Do you know whether there was a kernel upgrade done? I.e. are the modules in /lib/modules newer than v5.10.81? On a quick look at the Armbian APT repository it seems like it is still the newest "current" kernel, but probably the repos are still syncing.

If a kernel upgrade was done, can you try to flash the new U-Boot:

. /usr/lib/u-boot/platform_install.sh
write_uboot_platform "$DIR" "$(lsblk -npo PKNAME "$G_ROOTFS_DEV")"

Hi MichaIng,

Thanks a lot for the very fast reply. I executed both commands without errors but after that the result is the same.

I checked the version from the dietpi-config advanced options. --> The current version is Linux 5.10.102-meson64

[MichaIng]

Okay, so probably the kernel upgrade from 5.10.81 to 5.10.102 is responsible. If you have a spare card/drive, could you try it with the current Armbian image, please: https://dl.armbian.com/odroidc2/Bullseye_current
If so, it should be reported here: https://forum.armbian.com/forum/16-amlogic-s905x-s922x/

Btw, how long did you wait before power cycling? Probably there is one service/unit hanging on shutdown. A maximum timeout for any hanging ExecStop command or such should be 90 seconds.

Hi, I waited even 10 mins without luck. When I plugged the screen on the hdmi port I saw the job with the counter for 1min 30 secs stopping other tasks, that counter finishes even earlier but when all is halted and I get the black screen the new boot never happens.

I have another SD card so today I'll try to use the iso of your link "[Bullseye_current]" (The web SSL cert expired a couple of days ago :D). I'll be back asap with the results.

I have a similar error as commented by a user of an Odroid C4 in your second link:

Thanks for your help!

Well, confirmed, is a kernel topic. After installing armbian I have the same problem. I reported the isue as you suggested --> https://forum.armbian.com/topic/20241-odroid-c2-never-starting-after-a-soft-reboot-reboot-command/

The universe is telling me to go back to my dietpi from Sep 2021 :D the best option for my Odroid C2 rightnow (preserving the possibility to have the fs-boot in an external drive).

Thanks again for the help!

[MichaIng]

Could you try it with the edge kernel? At least the automated smoke tests, which include a restart test, go through with it:

apt install linux-image-edge-meson64 linux-dtb-edge-meson64 linux-u-boot-odroidc2-edge

Hi MichaIng,

Sorry I don't want to spend more of your time and mine. I went back finally to the last iso I had from Sep 2021 and I got back the option to run the "root fs" from my external usb ssd. It is working like a charm so I don't really need to run the last version.

Thanks for your help and time!

[yandritos]

I'll continue with the last year version untill a real/relevant reason avoid me to do that :)

[MichaIng]

Let me reopen the issue to keep track of it, since staying on old kernel with vulnerabilities like dirty pipe is not an option for the image we provide.
