Hello all! I'm novice here. I use in my device FPGA ХС3S1400АN (Xilinx Spartan-3AN family). I use to configure a Xilinx parallel cable III and tool xc3sprog. Command string for configuration is below "xc3sprog-c pp -Ibscan_spi/хс3s1400аn.bit FileToISF.bit" and works perfectly! File "bscan_spi/хс3s1400аn.bit" is a part of Papilio-Loader-master. And I donnt know how it works. Can I see the original project for the file xc3s1400an.bit from location "Papilio-Loader-master\xc3sprog\trunk\bscan_spi\xc3s1400an.bit"? Where? Thanks everyone in advance for any answer! Regards, Evgeniy
