Hello, I had Yellow PoE working fantastic since I got it, 2 months ago, and this morning it stopped working and will not respond to pings.
Here are my troubleshooting efforts step by step (HW config at the end)
-
The green LED flashes 8 times with a few seconds between each burst which means SDRAM Failure (raspi documentation).
-
Assuming that the NVMe M.2 is the issue, I removed it and tried to reboot the board (the NVMe was configured for storage only while eMMC still has HAOS and HACore).
-
Removing the NVMe did not solve the issue, the green LED continued as described in 1 above.
-
I then attempted to re-install HA as described in the yellow documentation here. Option 1 using the red and blue button did not work. I therefore moved to Option 2 using rpiboot. That too did not work (see rpiboot output below). The eMMC does not show up as a drive on a Windows PC and thus I cannot image HA onto the eMMC.
I am now back to where I was at the beginning.
Any hints or suggestions would be greatly appreciated.
