Default Boot Configuration
3-2
3.1 Default Boot Configuration
Out of the box, the DVEVM starts the demos automatically after a few
seconds when you power up the board. It does not require an NFS mount
or a TFTP server to run the standard demos. A DHCP server is required
by default; the DHCP service provided by most routers is sufficient to run
the demos. By default, the DHCP server obtains dynamic IP addresses.
To abort the standard boot, press any key in the console window (see
Section 2.2). Also see Section A.5,
Alternate Boot Methods if you want to
change the boot configuration.
3.2 Starting the Standalone Demos
When you connect the DVEVM hardware, the pre-loaded examples run
automatically on the LCD display. These examples encode and decode
audio, video, and speech. There are two ways to use the demos:
❏
Standalone. This is the default power-on mode. The demos run
automatically with no connection to a workstation in the default boot
configuration.
❏
Command line. Once you have connected the DVEVM to a
workstation and installed the necessary software (as described in
Section 4.3.1,
Installing the Target Linux Software ), you can run the
demos from the board’s Linux command line as described in Section
A.1,
Running the Demos from the Command Line .
Once the DVEVM board has booted, the LCD display should show a
picture of the remote control. You use the IR remote to control the demos.
To use the demos in standalone mode, follow these steps:
1) Check to make sure the batteries are installed in your IR remote.
2) The initial screen shows a diagram of the IR remote, which you use
to run the standalone demos. Take a minute to look at the functions
of the various buttons.
3) Since this is a universal remote, you may need to set it to use the
codes necessary to run the DVEVM demos. To do this, hold down the
"Code Search" button until the red light on the remote stays lit. Then
press the "DVD" button and enter "020" as the code.
4) If you accidentally put the remote in TV or some other mode, press
"DVD" to return the remote to the correct mode.
5) If the remote does not accept the DVD+020 code, do a full reset by
removing the batteries, pressing the power key for at least a minute,
then reinserting the batteries. Then program the remote as in Step 3.
