Hi,
I'm not terribly familiar with programming FPGAs - and I'm sure I'm not alone on that. Are there some simple instructions describing equipment required, and how to program?

Do you foresee any problem programming the FPGA on 3rd party 'clone' avalon miners (e.g. lketc's avalon3 miner)? They seem to have much different electronics layout and it is quite possible that they tweak the source to match their design (it's impossible to tell for sure, as they do not provide source code).
