Kit, Stratix IV GX Edition page of the Altera website to determine if you have the
latest kit software.
Using the Board Update Portal to Update User Designs
The Board Update Portal allows you to write new designs to the user portion of flash
memory. Designs must be in the Nios II Flash Programmer File ( .flash ) format.

Design files available from the Audio Video Development Kit, Stratix IV GX Edition
page of the Altera website include .flash files. You can also create .flash files from
your own custom design. Refer to “Preparing Design Files for Flash Programming”
on page A–2 for information about preparing your own design for upload.
To upload a design over the network into the user portion of flash memory on your
board, perform the following steps:
1. Perform the steps in “Connecting to the Board Update Portal Web Page” to access
the Board Update Portal web page.
2. In the Hardware File Name field specify the .flash file that you either downloaded
from the Altera website or created on your own. If there is a software component
to the design, specify it in the same manner using the Software File Name field,
otherwise leave the Software File Name field blank.
3. Click Upload . The progress bar indicates the percent complete.
4. To configure the FPGA with the new design after the flash memory upload process
is complete, set the rotary switch (SW2) to the 1 position and power cycle the
board, or press the CONFIGN button (S1).
As long as you don’t overwrite the factory image in the flash memory device, you can
continue to use the Board Update Portal to write new designs to the user portion of
flash memory. If you do overwrite the factory image, you can restore it by following
the instructions in “Restoring the Flash Device to the Factory Settings” on page A–4 .
