Now I have: http://dl.dropbox.com/u/23683845/fpgaminer-virtex5.zip
You'll need to adjust the line "constant DEPTH : integer := 6;" (2^n pipeline stages) in top.vhd.

Hi All.  I am trying to implement the following on a Virtex 6. DCMs are no longer used on the Virtex 6 and have been replaced with MMCMs. So far I have swapped the DCM for an MMCM and am able to implement the design.  But when I try to run the python script, it fails. I get a "Got bad message from FPGA: 240".  I would appreciate any guidance you could provide. Thanks.
As you're probably not running at 120MHz you'll need to adjust the UART clock divider.
If you provide your clock frequency I can calculate the correct values for you.

Oh, and it would be interesting which Virtex 6 model this is, which frequency you can reach and how many LUTs/slices/FFs are used.
