I've scoured this thread but I'm sure I missed the answer to my problem, so sorry in advance!
I received my FULL and my STANDARD yesterday, and when hooked up to power, only the STANDARD mines. The FULL module is correctly syncing to the chain (it's at 69% after 12 hours) but does not mine.
I've re-seated the SD card, tried a different PSU, and have restarted and rebooted and re-everything'd a bunch of times. I've tried different pools, too.
Ideas for next steps?
I suggest to first concentrate on full unit. Do not connect anything to it, just make sure it works all right. Reinstall SD card if need be, check all connections etc, full miner must work. Only when you achieve it, try and experiment with connecting secondary standard unit to it via USB cable.
Well, after 6 hours of mining as a working Full model, it is back to not mining again XD
Now I think I have two choices...run the SBC separately with power and hook up miners via USB, or scrap the Node and just run the Standard units off a RasPi. What do you think?
FutureBit won't take it back as I've messed with it too much in trying to troubleshoot. I have no problem running it as a controller+3 standards. Just curious what everyone thinks is a good next-step.
