EDK 7.1, Virtex4 GPIO PULLIP problem


a quick question I have and microblaze in Virtex4 (EDK 7.1 SPx), the system has several GPIO instances it all works OK until I try to add "PULLUP" on the second GPIO port, then there will be several DRC errors complaing that OLOGIC_OFF1 must have signal on CLOCK pin.

I see no difference between the 2 GPIO instances in my system, but on one of them the IOB PULLUP can not be used, or it seems so.

any ideas for workaround ??
