Stratix IV GX Edition User Guide
A. Programming the Flash Device
There is a common flash interface (CFI) type flash memory device on the
Stratix IV GX transceiver signal integrity board. When you first receive the kit, the
CFI flash device arrives programmed with a default factory FPGA configuration for
running the Board Update Portal example design and a default user configuration for
running the primary transceiver signal integrity demonstration. There are several
other factory software files written to the CFI flash device to support the running of
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 Design application.

Board Update Portal CFI Flash Memory Map
Table A–1 shows the default memory contents of the 512-Mb (64-MB) single-die 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.
Using the Board Update Portal or Nios II EDS tools, you can update the user flash
configuration with designs provided on Altera’s website for demonstration and
evaluation. For more information, refer to
“Board Update Portal” on page 5–1 .
c Altera advises against overwriting the FACTORY HW or SW images unless you are
expert with the Altera tools or overwriting the factory design is deliberate. If you
unintentionally overwrite the FACTORY HW or SW images, refer to
“Restoring the
Factory Design to the Flash Device” on page A–4 .
