Also, when I run "sudo /opt/bitfury/start-miner.sh" I get an error of "cp: cannot stat '/opt/bitfury/empty_stat.json': No such file or directory".
Run this: "touch /opt/bitfury/empty_stat.json". Then try "sudo /opt/bitfury/start-miner.sh" again. After running that, wait about 30 seconds or a minute and "cat /run/shm/.stat.json", that will show a summary of what your boards are (or aren't) doing.
Now start-miner.sh executes but when I run "cat /run/shm/.stat.json", I get "cat: /run/shm/.stat.json: No such file or directory"
Can you try uploading your working raspberry pi's sd card contents? It just seems like nothing is working with the image from black arrow's website...
