Configuring from SPI Flash R
Creating an SPI Serial Flash PROM File
The following steps describe how to format an FPGA bitstream for an SPI Serial Flash
PROM.
Setting the Configuration Clock Rate
The FPGA supports a 12 MHz configuration clock rate when connected to an M25P16 SPI
serial Flash. Set the Properties for Generate Programming File so that the
Configuration Rate
is 12, as shown in Figure 12-5 . See “Generating the FPGA
Configuration Bitstream File” in the FPGA Configuration Options chapter for a
more detailed description.
Regenerate the FPGA bitstream programming file with the new settings.
