Hi Martin, I didn't find a link to the message, but here's Larry's revised code: http://recycle.lbl.gov/~ldoolitt/xguff.html His gadget uses a Spartan 3, but as I recall, the fix is in the resetting of the buffers and/or in their initialization. I think a basic diff should turn up the changes. We haven't really touched the FX2 code in a couple of years.
