Running the Network Demo

As an example of standard TCP/IP networking support, the DVEVM
examples include a small HTTP web server. This web server is started
on the GPP-side as part of the Linux startup sequence. It configured to
service requests from web browsers on the standard TCP/IP port 80.

After the EVM board has booted, connect a PC to the same network to
which the EVM board is connected. Enter a URL of the form "http://ip-
address-of-evm" in a web browser (for example, Internet Explorer,
Firefox, or Opera). The IP address of the board is shown in the lower-right
corner of the main menu of the A/V demos.

You should see a web page with information about DaVinci technology
and the DVEVM software.

Use this web page to interact with the board and run the A/V demos
described in Section 3.3, Running the Standalone Demos. Two simple
CGI scripts on the EVM enable you to start the demos (assuming they are
not already running) and see what processes are running on the board.
If you want to see the demo started from the web page, be sure to exit
the demo first (use the Power button from the main menu).

The web server software is an open-source package called THTTPD
(http://www.acme.com/software/thttpd/). It is designed to be small, fast,
and portable. The source code is included with the DVEVM software. You
can get the latest version directly from the web. The web server and CGI
scripts are installed on the target in the /opt/dvsdk/dm6446/web directory.
