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 starter board and how to
reprogram the user portions of the flash memory device.
The Arria V GX starter 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 (U12).
Each flash device has a 16-bit data bus, and the two combined flash devices allow for
a 32–bit flash memory interface. 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 .
