Why vim4 needs 'Power On/off button' at first boot?

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


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

self built images and official images too

Please describe your issue below:

Probably from 8/26 version, it seems that the button is required for the first power input.
Even oowow doesn’t seem to work properly if there is no button input.

Hi @Jeter

If need to press POWER key to bootup, it maybe 2 reasons:

  • WOL is enabled
  • DCIN is disabled

You can follow the steps below to disable press POWER key to bootup.

  1. Boot to OOWOW
  2. Select: Exit->Rescue shell
  3. Execute the commands below
i2cset -f -y 6 0x18 0x21 0
i2cset -f -y 6 0x18 0x25 1

Then unplug the power cable and plugin the cable again.

Thanks to fast reply
My case is WOL is enabled, and the solution is effectable
