how to config fpga with flash?

Hi,

There are two types of Parallel Flash Loader(PFL). One is implemented to MAX II or other CPLD. It writes data from JTAG to Flash and loads data from Flash to any FPGA device. A function writing data from JTAG is called programmer, and one loading to FPGA is called loader.

Another is implemented to FPGA. It writes data from JTAG to Flash and is programmer only. Loader? Only the Cyclone III FPGA has dedicated loader circuit to load from Flash, and this must be the way to configure FPGA in your board. It is described in AN-478.

Probably you can use the "Factory Default PFL", so you just convert sof to pof instead of jic. All the pins for PFL are dedicated in the Cyclone III, so you don't need to assign them.

Thanks,
