    Hi, I just got started with Papilio Pro last week (side note: Great work with the papilio family and wings.. Im really excited about the board's potential). The Pro was my first entry to the papilio line. I was mostly able to figure out how to get the board running and programming. But, many of the instructions/downloads on the papilio website are either outdated or directed towards Papilio One, so getting started took about 4 hours longer than I expected. I thought I'd put together a list of links and instructions for problems I encountered along the way so that perhaps others starting with the Papilio Pro could have something up-to-date (well, as of April 2013, that is): 1. Windows FTDI Drivers: I had some real trouble getting the Papilio recognized as both a USB and a virtual COM port. For my problem, the device was ALWAYS recognized on Windows-- even when I did not have the Gadget Factory drivers installed. And it never showed a virtual COM port. Troubleshooting suggests using a different cable, or editing the device properties. Apparently in my situation, the Papilio was recognized as an FTDI device first and was not using the Gadget Factory drivers. My solution: Download the FTDI CDM Uninstaller. Using FTDI's USBView utility, find the Device Vendor ID and Product ID. Use the CDM Uninstaller to uninstall the FTDI drivers for the Papilio. After plugging and replugging, Windows recognized a virtual COM port. I could also connect through putty and see the default ASCII table output which was apparently the factory default program. 2. Getting Started Bitfile: http://papilio.cc/index.php?n=Papilio.GettingStarted It appears as though the getting started website (as of April 5 2013) does not include the getting started bit file for Papilio Pro. In my beginner state, I assumed this website would have the materials I needed, so I fumbled around trying to use the Papilio One 500K bitfile. After a while, I realized it certainly doesnt make sense to try to use the Papilio One bitfile, especially since the Papilio Pro uses a completely different FPGA. I dont think I've found a replacement for the "Getting Started" bitfile for the LX9 yet. 3. Papilio Loader: As with the bitfiles, the Papilio Loader GUI on the Getting Started Page is out of date (it downloads v1.7). According to a forum discussion around December 2012, the Papilio Loader was modified to support the Papilio Pro. Download the Papilio Loader GUI specifically from the Downloads webpage (this should be version 2.1 or later): http://forum.gadgetfactory.net/index.php?/files/category/2-papilio-fpga/ 4. ZPUino Core and Loader: I think the official ZPUino download page is a little out of date for Papilio Pro. It looks like the papilio website ZPUino getting started guide is out of date too- It uses an old version of the IDE and does not include links for the Papilio Pro bitfiles. Instead a forum post indicates the RetroCade installer works with the Papilio Pro. So, to get the ZPUino to work, download the Retrocade Synth Windows Installer from the Download Page. Use the bitfile ZPUIno_SOC/zpuino-1.0-PapilioPro-S6LX9-RetroCade-1.0.bit to program the Pro. The installer should also include a version of the Arduino GUI which includes a board option for ZPUino on Papilio Pro (LX9). 5. Intro to FPGA Book: With a functioning Papilio Loader and a ZPUino core/ GUI, I was basically good to go with the Intro to FPGA E-book. I also installed the Xilinx toolchain as instructed. No issues there. I'm looking forward to generating and programming with my own bitfiles shortly. It would, however, be nice to have an updated Xilinx webpack quickstart page: http://papilio.cc/index.php?n=Papilio.XilinxISEWebpackQuickStart. EDIT: I installed the wrong Xilinx tools at first. The default link inside the Intro to FPGA E-book now leads to the Xilinx Vivado suite, which doesnt support the Spartan 3 or Spartan 6 series. Instead, make sure to download and install the ISE Design Suite. 6. Papilio Arcade: I also tried the papilio arcade wing. Just make sure to download the correct LX9 bit files from the github https://github.com/GadgetFactory/Papilio-Arcade I havent looked at the AVR8 softcore processor. This is on my list to test with the Papilio Pro, along with some other fun things (SoC editor is on the horizon too). Like I said, Im a big fan of the board. Overall, it looks to be a really great FPGA. I do want to see the usability/ learning curve get to the Arduino level, and it helps to have a good getting started procedure for all boards. Hopefully this helps another beginner in the same situation. Thanks for all the work so far! EJ
