LED decoder ring
The LEDs are numbered 1 to 8 with #1 closest to the USB connector and #8 closest to the power and fan connectors. During first power up, LEDs 5, 6, 7, and 8 will light up and LEDs 1, 2, 3, and 4 will indicate a failure code if anything is wrong with the hardware. This happens VERY quickly - in less than a second.
If the initial hardware checks are good, #7 will blink indicating it is waiting for the board to cool down. This will always blink for a few seconds even if the board is cold.
Then #7 and #8 will blink indicating ASIC self test.
After that, 1, 2, 3, 4 will indicate how many jobs from cgminer are waiting to run in the input queue. LED 5 is just a debug output for me but it roughly indicates a job has completed - but sometimes blinks too fast for the human eye to see. Just ignore LED 5.
I am working on some firmware updates that will fix most (or all?) of the problems the boards are having. For example, one failure I think I have figured out is occasionally a board will jump to more than 100 GH/s but have 100% hardware errors. I have one board that does this once per day or so and needs to be rebooted. After chasing this for a while, I believe I have finally figured out what is going on and will have a fix in the next release.
Hi,
what does it mean if a board leds 1-4 will be stay off and 5-8 will be stay on? No usb connection is registred if I plug in on my linux box? TP5V and TP3V3 are looking fine with measured 4,99V and 3,38V.
I registred the problem on one board before mounting the bgas and on one board after mounting the bgas, so maybe the problem allready exists before I mounted the chips.
Cheers,
Please reserve 8 Minion chips for me, if MrTeal and ChipGeek would do it.
