OpenMarine

I have taken my  Raspberry pi  , with  MacArthur HAT  and power modul home  . for winter .
When i power up  ,   i can see on the monitor it ,   but after few  sekund  it say  plymoth halt .

on the boat i have  enabled  SW power ,  now i dont have that socket  .   is that the problem  . 
or is there a solution ?

Unfortunately, the Pi doesn't detect whether it's powered from the HAT or USB, so it will shut down when the power-down logic is configured in the OpenPlotter settings.

If you don't have a 12V source to boot up the Pi and change the configuration of OpenPlotter, you may be able to fool the shut-down logic by connecting the 12V SW input to 5V on the Pi. The high voltage after the voltage divider (~1.24V) is marginal for the Pi to detect as a 1, so not sure if this will work.

Thanks  will try it later
