Now if I could just find someone who has Monarchs working with an rPi. It's utterly ridiculous these days to have to use a PC as a controller.
I would be one of them although I'm running them on Ubuntu 14.04 and Windows right now. But I do have cgminer 4.6.1 configured for running two Monarchs on rPi/raspbian OS.
There was a thread about running BFL stuff on rPi but I don't think I've read it. I like to bang my head against a wall and try things myself. Then maybe rtfm and correct the mistakes if needed.
So to put the long story short is:
a) install raspbian on an SD card, use google and RTFM if necessary
b) don't configure and install a GUI, just stay with the command line stuff
c) google howtos about installing cgminer on Linux and do the same, but make sure to get cgminer 4.6.1
d) configure cgminer with "--enable-bflsc" flag
e) compile cgminer
f) run cgminer: sudo ./cgminer
g) configure the pools
h) plug in the Mofarchers
i) profit
Make sure cgminer has write access to cgminer.conf so the changes made are really saved in the file. I'm a Linux noob so this is a very rudimentary "howto".
An extra step would be to install a web server and copy the "miner.php" file from the cgminer folder to the public server folder and then enable api/network access in the cgminer.conf. Then you could access your mining stats anywhere in the world.
