My Antminer S2 is down too, and a new SD card doesn't help either. I'm new to computers, bitcoin mining and electronics so I don't really see myself doing all of this to replace the beaglebone.

Here's my question: does anyone think a raspberry pi could take over the beaglebone's job ? If I just connected it to the control board of my S2 ?

I have BFG miner on my rasp and it says among others : drivers enabled : antminer

Many thanks for any advive !
