Siddharth 0 Report post Posted March 12, 2017 I just got a new Papilio one-500k and logicstart megawing. I loaded Quickstart-Papilio_One_500K-v1.5.bit file onto the board and LEDs blink as expected. But when I load any other bit file other than the Quickstart nothing works, I followed Hamster's IntroToSpartanFPGA Book and made my first project of turning on LEDs using switch but I'm not getting the output.

james1095 13 Report post Posted September 1, 2017 Usually when something like this doesn't work, it comes down to a problem with the .ucf file that assigns the IO. It has to be tailored to the specific board and wing in order to work, otherwise ISE will put the signals on the wrong pins. Share this post Link to post Share on other sites
