A.2. Programming Flash Memory

This appendix describes programming information for the following memory devices:
  • Common flash interface (CFI) flash memory
  • Quad serial peripheral interface (quad SPI) flash memory
  • SD card flash memory

The Cyclone® V development board's flash memory ships preconfigured with the parallel flash loader (PFL) option bits to support FPGA designs to be written to any of the three locations as shown in the Byte Address Flash Memory Map table. The PFL is disabled by default. Set SW2.3 to ON to enable FPGA programming from CFI flash memory on power up.

There are several other factory software files written to flash memory to support the Board Update Portal. These software files were created using the Nios® II EDS, just as the hardware design was created using the Quartus® Prime software.
