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 Stratix V GX 100G development board and

the Nios II EDS tools involved with reprogramming the user portions of the flash

memory device.

The Stratix V GX 100G 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.

f For more information about Altera development tools, refer to the Design 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–4.
