Thx for your work you put in the miner!
I ported the Xilinx_VHDL miner to the ml605 dev board.
Actually, straight forward ... Replaced the dcm with a newer Virtex6-aquivalent, wired the pins to rs232 and clock, adjusted the baud rate and it run instantly.
It does 200MHash/sec and is user by about 85% ...
