I'm trying to use xc3sprog with FT2232H. My chips are XC3S200 FPGA and XCF01S PROM. They are recognized and I can program them, but only when I have LPT<->jtag programmer cable also connected. When this programmer is unplugged, chips are recognized but I can't program. I can only erase PROM. But the output of xc3sprog looks like all is done

jtag pins are not for use.
They are fixed from Xilinx, you can't map as others pins.
You can leave unconnected or (i think better ) refer at vcc or GND (according whit data shhet specifications)

You are still misunderstanding the suggestions in the other thread.
They have been talking about a way to program the serial flash through jtag. A working jtag connection to the FPGA is required for indirect jtag programming as well as debugging.
