Programming other FPGA's/CPLD's with Papilio in Papilio General Discussion Posted August 1, 2013 · Report reply The Papilio Pro has JP4 which will hold the FPGA in a reset mode which allows you to connect the JTAG pins from the JTAG header to any device you want and use the FT2232 to program them. Any Xilinx part should be supported by the Papilio Loader using this method. Jack. Ah. So there isn't any option like shorting a pin or something for the Papilio One?
