December 2011 Altera Corporation Transceiver Signal Integrity Development Kit,

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.
