If I upgrade my device from 2.5 to 3.0 and I load my design I have a USB communication error. In the files I see that al the control signals (HI) are in one databus now. It wasn’t before. So I change my pinfile(UCF) to the new version and also the VHDL in Mentor Graphics. But now I get, when loading the bit file an communication error.
What I see in the difference between these files, is that the 3.0 version have one more bit for the host interface, signal hi_in(3).
I don’t know what I do wrong. Can anybode tell me
