A. Programming the Flash Memory Device
This appendix describes the pre-programmed contents of the common flash interface
(CFI) flash memory device and how to reprogram the user portions of flash memory.
As you develop your own project using the Intel tools, you can program the flash
memory device so that your own design loads from flash memory into the FPGA on
power up. The FPGA development board ships with the flash memory preprogrammed
with a default factory FPGA configuration. This configuration allows you to run the
Board Update Portal design example and the Board Test System demonstration. There
are several other factory software files written to the CFI flash device 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 Intel Quartus Prime software.
For more information about Intel development tools, refer to the Intel Quartus Prime
Software Suite and FPGA Development Tools page of the Intel website.

A.1. CFI Flash Memory Map
The following table shows the default memory contents of the 1 Gb CFI flash device.
For the Board Update Portal to run correctly and update designs in the user memory,
this memory map must not be altered.
