Download FPGA designs directly to the Spartan-3E FPGA via JTAG, using the on-
board USB interface. The on-board USB-JTAG logic also provides in-system
programming for the on-board Platform Flash PROM and the Xilinx XC2C64A CPLD.
SPI serial Flash and StrataFlash programming are performed separately.
Program the on-board 4 Mbit Xilinx XCF04S serial Platform Flash PROM, then
configure the FPGA from the image stored in the Platform Flash PROM using Master
Serial mode.
Program the on-board 16 Mbit ST Microelectronics SPI serial Flash PROM, then
configure the FPGA from the image stored in the SPI serial Flash PROM using SPI
mode.
Program the on-board 128 Mbit Intel StrataFlash parallel NOR Flash PROM, then
configure the FPGA from the image stored in the Flash PROM using BPI Up or BPI
Down configuration modes. Further, an FPGA application can dynamically load two
different FPGA configurations using the Spartan-3E FPGA's MultiBoot mode. See the
Spartan-3E data sheet (DS312) for additional details on the MultiBoot feature.
