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?
