5. Board Update Portal
Introduction
The Audio Video Development Kit, Stratix IV GX Edition ships with the Board
Update Portal example design stored in the factory portion of the flash memory on
the board. The design consists of a Nios II embedded processor, an Ethernet MAC,
and an HTML web server.
When you power up the board with the rotary switch (SW2) in the 0 position, the
Stratix IV GX FPGA configures with the Board Update Portal example design. The
design can obtain an IP address from any DHCP server and serve a web page from the
flash on your board to any host computer on the same network. The web page allows
you to upload new FPGA designs to the user portion of flash memory, and provides
links to useful information on the Altera website,
including links to kit-specific and
design resources.

After successfully updating the flash memory user design, you can load the user
design from flash memory into the FPGA. To do so, set the rotary switch (SW2) to the
1 position and power cycle the board.
The source code for the Board Update Portal design resides in the <install
dir>\kits\stratixIVGX_4sgx230_av\examples directory. If the Board Update Portal is
corrupted or deleted from the flash memory, refer to
“Restoring the Flash Device to
the Factory Settings” on page A–4 to restore the board with its original factory
contents.
Connecting to the Board Update Portal Web Page
This section provides instructions to connect to the Board Update Portal web page.
1 Before you proceed, ensure that you have the following:
■ A PC with a connection to a working Ethernet port on a DHCP enabled network.
■ A separate working Ethernet port connected to the same network for the board.
■ The Ethernet and power cables that are included in the kit.
To connect to the Board Update Portal web page, perform the following steps:
1. With the board powered down, set the rotary switch (SW2) to the 0 position.
2. Attach the Ethernet cable from the board to your LAN.
3. Power up the board. The board connects to the LAN’s gateway router, and obtains
an IP address. The LCD on the board displays the IP address.
4. Launch a web browser on a PC that is connected to the same network, and enter
the IP address from the LCD into the browser address bar. The Board Update
Portal web page appears in the browser.
