First, turn off the power on the Spartan-3E Starter Kit board.
If the USB cable is attached to the board, disconnect it. Simultaneously connecting both the
USB cable and the parallel cable to the PC confuses the iMPACT software.
Connect one end of the JTAG parallel programming cable to the parallel printer port of the
PC.
Connect the JTAG end of the cable to Header J12, as shown in
location of Header J12 is more clearly shown in
connects directly to the SPI Flash pins; it is not connected to the JTAG chain.
The JTAG3 cable directly mounts to Header J12. The labels on the JTAG3 cable face toward
the J11 jumpers. If using flying leads, they must be connected as shown in
and
Table 12-2: Cable Connections to J12 Header
Insert Jumper on JP8 and Hold PROG_B Low
The JTAG parallel programming cable directly accesses the SPI Flash pins. To avoid signal
contention with the FPGA, ensure that the connecting FPGA pins are high-impedance.
Force the FPGA's PROG_B pin Low by installing a jumper on JP8, next to the PROG push
button, as shown in
surrounding landmarks.
