Had my OSPi 1.43+ (0 Ohm shunt variant) running for a while, then my 24V power supply failed. Winter meant rain, so I didn’t get to it for a while. The Pi kept running on the µUSB for a while. Now, I got a replacement 24V power supply and tried to get it back up. The Pi boots when on its own, but if I attach to the OSPi I get an occasionally blinking green light on both OSPi and RPi, synchronous. Thought this might be a low power issue, so I replaced the 1A power supply with a 2.5 or 3A power supply, but I only get a brighter green flash from both LEDs. Now I also find my brand new 24V power supply is dead just during testing.
I’d had it configured with both power supplies connected through the OSPi, but even with only the Pi and ethernet connected, all other connections removed from OSPi, the Pi still won’t boot.
Does this mean I’ve got a dead OSPi, or is there something that can be tried?
