Programming Platform Flash PROM via USB
Generating the FPGA Configuration Bitstream File
The on-board USB-JTAG circuitry also programs the Xilinx XCF04S serial Platform Flash
PROM. The steps provided in this section describe how to set up the PROM file and how
to download it to the board to ultimately program the FPGA.
Before generating the PROM file, create the FPGA bitstream file. The FPGA provides an
output clock, CCLK, when loading itself from an external PROM. The FPGA’s internal
CCLK oscillator always starts at its slowest setting, approximately 1.5 MHz. Most external
PROMs support a higher frequency. Increase the CCLK frequency as appropriate to reduce
the FPGA’s configuration time. The Xilinx XCF04S Platform Flash supports a 25 MHz
CCLK frequency.
