Coregen creating Tri-mode Ethernet MAC Wrapper v1.6 with wrong FPGA

I'm trying to use the Tri-mode Ethernet MAC Wrapper v1.6 on an XUPV5 board. When I create a coregen project I select the lx110t but when it creates a design the .ucf file has all the connections for the lx50t (ML505). The resulting bitstream gets created for the lx50t which Impact obviously doesn't like and tells me the ID codes are mismatched. I tried modifying the .ucf with the lx110t as the part number, changed the GTP_DUAL LOC to X0Y4 (I think this is correct) and changed the MGTCLK_N LOC from Y3 to P3 and MGTCLK_P LOC from Y4 to P4. I must be missing something because I get no communication and even the ethernet LED's no longer light up with this change.

 

So, I'm not sure why coregen is doing this and I can't seem to solve this issue with some simple ucf modifications. Any help would be appreciated.

I've got the same problem using tri-mode ethernet wrapper 1.5.

 

I'm currently downloading ISE 11.5 to see if the updated tools have fixed this, but we only have a license for ISE 10, and it seems rather silly to purchase thousands of dollars in software just to utilizes more features on a device we buy from Xilinx...

 

Have you found a way to get the MAC wrapper working on the lx110t?  I'm also facing the same issue on the fx100t.

Coregen don't know which board you're using. The LOC  is just for reference. You need to change the pin location for all your pins, such as clock, reset, GTP, LED, etc.
