Which system do you use? Android, Ubuntu, OOWOW or others?

Ubuntu 22.04

Which version of system do you use? Khadas official images, self built images, or others?

I use self built images

Please describe your issue below:

I run sudo poweroff
but the khadas start again.
I can’t turn Khadas off without unplugging the power.

@ozgedurgut can you share the serial console logs during the reboot ?

Are the logs correct?

@ozgedurgut is this from latest fenix image ?
what modifications have you made ?

This is my own image, I changed some things. base image is ubuntu 22.04
I started encountering this problem after doing the following:
I connected the bios battery to khadas. I set date and time. Then, I disabled and stopped the network manager service to test the bios.

sudo hwclock --systohc
apt install systemd-timesyncd
sudo systemctl status systemd-timesyncd
sudo timedatectl set-ntp true
sudo timedatectl set-local-rtc 1

And there are applications I deleted to shorten the boot time;

and I disable and stop these services;
snapd.seeded.service
snapd.service
snapd.socket

@ozgedurgut btw there is no bios in the systems.

Maybe these operations could cause the issue, I will check and let you know.

Try

$sudo shutdown now

@foxsquirrel It didn’t work. It shut down and then started again.

@Electr1 I enabled these and started;

snapd.seeded.service
snapd.service
snapd.socket

but nothing has changed.
Also,
I disabled and stopped this service but again nothing has changed.
systemd-timesyncd

Since I wanted the Khadas clock to stay updated even when it was not connected to the internet, I used RTC Battery and set the clock. When I say bios, I mean this, sorry.
sudo hwclock --systohc
apt install systemd-timesyncd
sudo systemctl status systemd-timesyncd
sudo timedatectl set-ntp true
sudo timedatectl set-local-rtc 1
That’s why I did these steps. Is there no need for these then?

It might be set up to do that, when power drops you want the system to reboot by itself. I know the big metal box servers are configured in bios for restart. Sorry, I just cannot remember where or if that is even possible with ARM boards.

Connect a ttl adapter to the linux debug port.
Use gtkterm and log the boot up and then shut down. You should see where it is restarting and find what to change.

@ozgedurgut there doesn’t seem to be any configuration that can do that.

Can you build latest fenix kernel-deb and check if the situation persists with updated kernel ?
