LVDS problem/chipscope VIRTEX4

Hey,

I just got a board with a virtex4 and there is a LVDS connection on it and another LVDS input bank where the clock oscillators are connected to. that bank is a Vcco=3.3V bank but has a 2.5V LVDS connection, but since

tPagePath=16830 says this is not a problem i hope this is not the problem.

Now the problem is that when i download the code and boot chipscope analyzer, the analyzer says it does not find any core (although there is a ICON/ILA core in it) and when i check with fpga editor there is indeed a ICON/ILA core. So that is why i thought that the clock generation is a problem (although the clk's are generated since i can see them at the input pad of the fpga)? especially since i cannot get anything out of the fpga, everything remains inactive for some reason...

i also get this warning:

ARNING:Xst:1474 - Core was not loaded for as one or more ports did not line up with component declaration. Declared input port was not found in the core. Please make sure that component declaration ports are consistent with the core ports including direction and bus-naming conventions. WARNING:Xst:1474 - Core was not loaded for as one or more ports did not line up with component declaration. Declared input port was not found in the core. Please make sure that component declaration ports are consistent with the core ports including direction and bus-naming conventions.

WARNING:Xst:1474 - Core was not loaded for as one or more ports did not line up with component declaration. Declared output port was not found in the core. Please make sure that component declaration ports are consistent with the core ports including direction and bus-naming conventions.

but since i've seen this warning in the past and chipscope worked i don't think this is the problem.

I hope some of you know where i can start looking since for now i don't have a clue ...

kind regards,
