Thanks! I'll also inspect the wiring harness for any wires that may have disconnected or snapped during shipment--another user suggested that.
Weeeeeell...same issue. I stopped the node (thus removing the load on CPU) and restarted the miner(s). No change--solid red light on FULL but STANDARD hashes away in Eco fine.
Will wait for blockchain to fully sync (90% currently) and retry all the rebooting steps.
I can't see any loose wires or anything, so if there's no progress after full sync, I guess it'll have to be returned and swapped out for a new FULL?
I stopped the node, and shutdown the full and stand. miners. I then swapped the SBC from the FULL (let's call it Miner 1) to the working STANDARD (now called Miner 2), fired it up and the exact same issue. Now it seems whatever "rectangular mining prism" the SBC is in becomes a non-working miner. Currently Miner 2 which had worked is now not hashing, and Miner 1 which had NOT worked is hashing.
Any thoughts of what next? I'll reply to my order email with what's going on.
This sucks.
**EDIT** Now the "new" STANDARD miner (which had been Miner 1) which is actually mining had been the original FULL that did not mine...what's scary is now that same miner is registering over 40% HW errors on Eco mode...
