Program the Spartan-3AN internal SPI Flash memory, then configure the FPGA at
power-up. This option is not available in the Spartan-3A Starter Kit.
Download FPGA designs directly to the Spartan-3A/3AN 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. SPI serial Flash and StrataFlash
programming are performed separately.
Program the on-board 4 Mbit Xilinx XCF04S serial
configure the FPGA from the image stored in the Platform Flash PROM using Master
Serial mode.
Program the on-board 16 Mbit STMicroelectronics SPI serial Flash PROM or the
16 Mbit Atmel SPI-based DataFlash PROM, then configure the FPGA from the image
stored in the SPI serial Flash PROM using SPI mode. Further, an FPGA application
can dynamically load different FPGA configurations using the FPGA's MultiBoot
mode. See UG332: Spartan-3 Generation Configuration User Guide for additional details
on the MultiBoot feature. See
using SPI serial Flash memory.
Program the on-board 32 Mbit STMicroelectronics parallel NOR Flash PROM, then
configure the FPGA from the image stored in the Flash PROM using BPI Up
configuration mode. Further, an FPGA application can dynamically load different
FPGA configurations using the FPGA's MultiBoot mode. See UG332: Spartan-3
Generation Configuration User Guide for additional details on the MultiBoot feature. See
