I have a RPI4 8GB with the official power supply. It’s been running HA fine for a couple of years, with HAOS on a USB-connected SSD (a 1TB Samsung T7.)
A couple of nights back, we had some power surges in the house, and now the RPI4 won’t boot anymore. It repeatedly loops in U-Boot with this message “Card did not respond to voltage select! : -110”, see screenshot.
Is my RPI4 fried? Or the SSD corrupt? Or what? All advice, suggestions welcomed.
Update: After about 15 minutes of boot looping, I do actually get an HAOS prompt.
Does this provide me with any chance to fix this thing?
Well, I was able to fix this myself.
-
I used the Raspberry Pi Disk Imager to create an SD HA image and found the RPi4 could boot OK from that. So the RPi4 didn’t appear to be fried.
-
I used Windows Services for Linux to take a copy of the last automatic HA backup from the data partition of the USB-attached SSD drive.
-
I used the Raspberry Pi Disk Imager again, this time to re-install a fresh HA image on the USB-attached SSD drive. The RPi4 was then happy to boot from that, and I could restore the last automatic backup, that I had rescued in the previous step. The HA is now working fine again.
And only now I find someone else had almost the same experience. Maybe we should try to find an affordable UPS-solution for HA. Spending upwards of $3K on a full UPS to protect a $100 RPi seems somewhat excessive.
Meanwhile, I should probably finally organise getting my backups off the local SSD. That would save me the 2nd step above, if the damage didn’t make that impossible anyway. It’s not as if HA didn’t make it easy enough to do.
Hehe. I forgot that I did actually have a cloud backup available, via Nabu Casa. Next time.
