User Guide
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 V GX FPGA development board and
the Nios II EDS tools involved with reprogramming the user portions of the flash
memory device.
The Arria V 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.

page of the Altera website.
CFI Flash Memory Map
Table A–1 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.
c
Altera recommends that you do not overwrite the factory hardware and factory
software images unless you are an expert with the Altera tools. If you unintentionally
overwrite the factory hardware or factory software image, refer to
“Restoring the
Flash Device to the Factory Settings” on page A–3 .
