Altera Arria II GX FPGA - Manual (Page 41)

A. Programming the Flash Memory
Device
As you develop your own project using the Altera tools, you can program the flash
memory device so that your own design loads from flash memory into the FPGA on
power up. This appendix describes the preprogrammed contents of the common flash
interface (CFI) flash memory device on the Arria II GX FPGA development board and
the Nios II EDS tools involved with reprogramming the user portions of the flash
memory device.
The Arria II GX FPGA development board ships with the CFI flash device
preprogrammed with a default factory FPGA configuration for running the Board
Update Portal design example and a default user configuration for running 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
Quartus II software.

CFI Flash Memory Map
Table A–1 shows the default memory contents of the 512-Mb (64-MB) CFI flash device
(Numonyx, PC28F512P30BF). For the Board Update Portal to run correctly and
update designs in the user memory, this memory map must not be altered.
