  1. Thanks so much for the help. I also got a pointer to http://xilinx.com/getlicense and that seems to have enabled the necessary parts of the tool. I've loaded & synethsized the socz80 project and am to the point where it needs to configure the target device. It starts iMPACT, which does not find my device. Is this normal? Is there just a device description file I should have pulled first? Or do I need to get that playtag stuff working first? I have it running and finding the two devices, but when I try to run it with a specific index (to start as a server) it seems to find the device busy. (For other newbies, it uses a libftd2xx.so which I found at http://www.ftdichip.com/Drivers/D2XX.htm). strace shows a lot of attempted accesses to libd2xx; is that yet another library I need to hunt down? I've put my user account under the dialout group so it has R/W to the ttyUSB[01] ports. I also made all the /dev/bus/usb device files a+rw, but none of this gets me beyond the part where it needs to know the target device. Thanks again, Andy
  2. I feel like I'm somehow not asking the right question, or it's somehow obvious to everybody else. I have a Papilio Pro (due to the socz80) and will certainly want to tweak the logic. How am I supposed to do that? I downloaded many gigabytes of stuff from Xilinx (ISE DS 14.7, multi-arch, I'm on x86 Debian) and told it to install. It told me how the tools were going to monitor me and phone home, and by the way I'd better enter my license. Does everybody here have a license? Did I pick up the wrong download? How do people here install/run tools to create new bits based on changing the VHDL? Once I have "compiled" VHDL bits, is it that Papilio-Loader which takes them and feeds them via a ttyUSB port to set up the FPGA? I see that *two* ttyUSB ports come into existence--is that expected? Which one is for which purpose? Thanks much, Andy Valencia
