5. Board Update Portal
This chapter explains how you can connect to the Board Update Portal and use it to
upload your own designs.
The Cyclone V GT FPGA Development Kit ships with the Board Update Portal design
example 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 SW4.3 DIP switch in the FACT ON (logic 0)
position, the FPGA configures with the Board Update Portal design example. 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 hardware 1 portion of flash memory and
provides useful kit-specific links and design resources.

After successfully updating the user hardware 1 flash memory, you can load a design
from flash memory into the FPGA. To do so, set the SW4.3 DIP switch to the FACT
OFF (logic 1) position and power cycle the board.
The source code for the Board Update Portal design resides in the <install
dir>\kits\cycloneVGT_5cgtfd9ef35_fpga\examples directory.
Connecting to the Board Update Portal Web Page
Ensure that you have the following items setup and installed:
■ 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, do the following:
1. With the board powered down, set the SW4.3 DIP switch to the FACT ON (logic 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. Start 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.
