cbeezy Posted July 13, 2014 Report Share Posted July 13, 2014 I've tried to do the first project in the Intro to Spartan FPGA book everyway I can think of and nothing seems to work. I'm out of ideas. Here's the details. Set up: --Papilio Pro Spartan 6 board--LogicStart Megawing on top of the board. --Xilnix ISE Webpack free license--Windows 7 (at first, then I tried ubuntu...same result). Anyways, I've followed the book and this youtube video: and I have yet to be able to throw the switches and see the LEDs light up. At first I thought it was the whole windows 7 driver thing..so I spent a few hours hashing that out..uninstalled the FTDI drivers using their uninstaller, etc...I think it's working alright, but I'm not sure. Anyways see attached for screen grab of my Device Manager with the board plugged in. After a few hours, I figured screw it. If it's a Windows 7 error thing, I'll just use my Ubuntu machine. I copy/pasted the bitstream file I made on my PC, to my Ubuntu machine...got Papilio Loader working..uploaded the simple program to the FPGA annddddd: ...same result. Nothing. I can load the QuickStart Bit file for the LX9 board and it does indeed work and flash the LEDs. It works the same on Windows or Linux. The LEDs blink. I've also followed this tutorial which taught a different pinout for the Megawing, as I thought perhaps I messed up the pinouts..still nothing. At this point I think three things: 1) I should have bought the Papilio one maybe. 2) I think the Megawing may be a bad unit (but on the other hand the Quickstart "hello world" bit file for the LX9 loads fine). 3) I may be an idiot. Any help would be appreciated. I'm out of ideas. Link to comment Share on other sites More sharing options...
