Thanks, I will try that. The fpga control board is version 1.6.1 and the light near the done marking is solid red. Red probably means bad but does anyone know specifically what it indicates?
On the Batch #2 Avalons, a red light generally occurred with a bad mining module. It may mean a power fault.
You might try disconnecting first 1 then the other module, and perhaps adjust the IDE cable so that the connected module is in position 1.
Can you see the chip side of the board, or is it covered with a heat sink?
Does this manufacturer connect the board up to eligius for a few hours to test it before shipping?
