My VIM4 keeps powering off after a couple of days. What can be done?

@mikev1963 Can you describe in detail, is it unable to boot or restarting repeatedly?

after VIM4 is running for a day or two I come back and see the power to the device is off. I have to unplug the power USB C cable and replug it in.

I am getting a lot of these errors in /var/log/syslog:

I guess the Khadas engineer does not care if the product works or not.

These information is not harmful.

  • Which system you used? Ubuntu or Android?
  • What application you have running?
  • How you identify the device is poweroff? What’s the status of LED at that time?

Then why does the device power off after a day or two

Here is what is in the logs right before it powered off:

Aug 30 13:17:09 khadas wpa_supplicant[708]: wlan1: Reject scan trigger since one is already pending
Aug 30 13:17:10 khadas systemd[1]: systemd-rfkill.service: Deactivated successfully.
Aug 30 13:17:10 khadas NetworkManager[674]: [1661865430.5680] manager: startup complete

Could you provide the full logs? There logs are not enough.

And we need more informations:

  • What’s the power supply you used? It is our 24W PD adaptor?
  • Which image you used? It is version 220721 ?

Did you get the logs and email I replied to?
