Dead MoPi? #113

Open mikcatta opened 5 years ago

mikcatta commented 5 years ago

Morning!

I am trying to test the MoPi to see if it will work for me in a certain situation.

The original MoPi I had from the kickstarter is giving me a "communication error on on read word", so I have purchased another from Pimoroni. This one worked for about 5 minutes, and then during the raspbian installation it shutdown and won't come back on. I am running it connected to the desktop PSU at 12v via source input #1. At the moment there are no lights on the MoPi at all. I have measured and there is a good supply of 12v at the PCB so I am confident the supply & leads are fine. Connecting the Pi to a 5v power supply, I am able to use that successfully without the MoPi.

Originally I wanted to see if it was possible for the MoPi to power up the Pi when the source voltage had recovered sufficiently. i.e. if the system was running from solar to charge the main batteries. It would be beneficial if it would shutdown at say 8v and the restart when the battery was back to 12v. Is this possible?

Its back and alive, not sure how/why/when! I am now getting "communications protocol error on read error" again! This is a PiZero by the way.

Question 2 still stands.
