Guest matthew180 Posted January 28, 2011 Report Share Posted January 28, 2011 I working on an FPGA end user product, i.e. the target user is not an electronics hobbyist, and I need to program the serial flash with the FPGA's bit stream. The device is very minimal (I only need the FPGA and 5v level shifter) so there will not be a USB chip on board. I really like the Papilion design, but I just don't need the USB chip on board. I'm looking for the easiest (and relatively inexpensive) solution. The FPGA is the Xilinx Spartan 3E (250K or 500K) and in reading the datasheet, it seems direct SPI programming can be done. Has anyone done this? The datasheet mentions that iMPACT supports this type of programming, but I'd like to hear someone's experience with going this route. The other alternative I was thinking about was to just make a FT2232-based programming dongle, basically the USB section of the Papilion on its own board. There seem to be a few of those types of "programmers" available, but everyone wants $100 or so for one. Ouch. Anyway, any insight would be greatly appreciated.
