hamster Posted October 12, 2013 Report Share Posted October 12, 2013 Hi! I've occasionally had problems like this when ISE has completely ignored the constraints (UCF) file. Check that in the Design Summary's Pinout report the the correct signals has been bound to the correct pin - in the "Constraint" column it should say "Located". If it doesn't remove the UCF file from the project, then add it back and build the project again. Link to comment Share on other sites More sharing options...

Jack Gassett Posted October 14, 2013 Report Share Posted October 14, 2013 I didn't realize that Girish was selling the 2.0 boards from the India store, those boards are not supported because of the drastic differences in the pinouts...
