Hi, my setup (somewhat underutilised, I’ll admit) has been plodding along doing its thing for about 5 years but when I went to check the other day after a power cut it looked like it was toast. I assumed SD card corruption since the lights and screen still worked.
I am running a Pi 2 B (I think) and it seems that the latest image to support that without issue is the one from 2017 (Jesse-based). So I flashed that on the card and plugged it all in again.
My first issue seems to be that the unit just displays its “DO NOT UNPLUG” updating message for what seems like forever. As far as I can tell it’s not updating. I can SSH into it at this stage so the Pi is alive.
When I eventually reboot it manually something bad has happened since it won’t get past the “Raspberry Pi Booting” stage. I have tried this several times with the same result.
When plugging in an HDMI cable to the Pi, I get no signal. Is this because the video out is disabled while the emonpi board is connected?
Any advice as to how to get back up and running (hopefully without having to splash out on a more recent version of the RPi) gratefully received.
