Setting Up the Hardware
2.1 Settin g U p the Hardware
To set up the hardware provided with the EVM, use the steps in the
sections that fo llow. You ma y sk ip secti ons if you do n ot ne ed to acce ss
a particular peripher al . Fo r examp le, i f y ou do no t n eed to us e the s erial
cable, skip that section.
1) The EVM is sensitive to static discharges. Use
a grounding strap or other device to prevent
damaging the board.
Be sure to connect communication cables
before applying power to any equipment.
2) If you use PAL video, set switch 10 on the S3 (USER) bank of
switches to On. If you use NTSC video, set this switch to Off. See
Figure 1–1 for S3 switch bank location.
3) Connect the yellow v ideo cable to the upper-rig ht Video Out jack on
the EVM and the LCD display Video Input as shown below.
See Section A.1, Changing the Video Input/Output Methods for
information about using S-Video or Component video.
2-2
Setting Up the Hardware
4) Connect the red and white audio cables to the EVM Audio Output
and the LCD display R/L Audio Input jacks as shown below:
5) Connect the BNC-to-RCA connector to the coax cable. Then connect
the coax cable to the video camera and the EVM Video Input.
6) Connect the power jack for the video camera. T o be ESD safe, do not
plug in the other end of the camera power cord until the later step that
instructs you to do so.
See Section A.1, Changing the Video Input/Output Methods for
information about using S-Video or Component video.
EVM Hardware Setup 2-3
Setting Up the Hardware
7) Connect the microphone to the EVM.
8) Connect the power cable to the EVM power jack on the board. To be
ESD safe, do not plug in the other end of the cable yet.
9) If you will use the Ethernet connection, connect the Ethernet cable to
the Ethernet Port on the EVM and to an Ethernet network port.
Note that the U-Boot bootargs must in clude "ip=dh cp" to enable the
network connection.
2-4
Setting Up the Hardware
10) If you plan to use th e UART port for a co nsole windo w, connect the
RS-232 null modem cable to the EVM UART port and a COM port on
your host Linux workstation. See Section 2.2, Connecting to a
Console Window for more about using a console window.
11) Plug in the LCD display to a power supply.
12) Plug in the NTSC/PAL video camera to a power supply.
13) Connect the power cable to the EVM power jack on the board. To be
ESD safe, plug in the oth er end of the power cable only aft er you
have connected the power cord to the board.
14) Power on the LCD display.
15) Power on the EVM board.
16) The initial sc reen of the demo software should b e displayed o n the
LCD display. Use the IR r emote to run the software a s describ ed in
Chapter 3.
EVM Hardware Setup 2-5
Connecting to a Console Window
2.2 Connecting to a Console Window
You can ope n a console window that allows you to watch an d interrupt
EVM boot messages by following these steps:
1) Connect a ser ial cable be tween the seri al port on the EVM and th e
serial port (for example, COM1) on a PC.
2) Run a terminal session (such as Minicom on Linux or HyperTerminal
on Windows) on th e workstation and config ure it to connect to tha t
serial port with the following characteristics:
■ Bits per Second: 115200
■ Data Bits: 8
■ Parity: None
■ Stop Bits: 1
■ Flow Control: None
3) When you power on the EVM, you will see boot sequence messages.
You can press a key to interrupt the boot sequence and type
commands in the U-Boot command shell. In this guide, commands to
be typed in the U-Boot shell are indicated by an
EVM # prompt.

Default Boot Configuration
3.1 Default Boot Configuration
Out of the box, the EVM boots from flash and 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.
Note: The default U-Boot bootargs definition sets "ip=off", which disables
the Ethernet connection.
The out-of-the-box boot parameters are listed in Section A.4.1. The
following are alternate ways you may want to boot the board:
❏ TFTP boot with hard drive file system (Section A.4.2)
❏ Flash boot with NFS file system (Section A.4.3)
❏ TFTP boot with NFS file system (Section A.4.4)
❏ PAL video mode vs. NTSC video mode (Section 4.3.7)
To abort the standard boot, press any key in th e console window (see
Section 2.2). Also see Section A.4, Alternate Boot Methods if you want to
change the boot configuration.
3.2 Starting the Standalone Demos
When you connect the EVM hardware, the pre-loaded examples run
automatically on the 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 wi th n o connection to a wor kstation in the defa ult boo t
configuration. This is the mode documented in the rest of this
chapter.
The standalone demo was se t up by the DVSDK, which copies the
file /examples/dvevmdemo to the directory /etc/rc.d/init.d (the central
repository for startup scripts). This file is symbolically linked to
/etc/rc.d/rc3id/S88demo. When the board boots up and enters
runlevel 3, this file is ex ecute d to s tart th e de mo we b s erve r and th e
demo interface.
❏ Command line. Once you have connected the EVM to a workstation
and installed the nec ess ar y software (as desc ribe d i n S ec ti on 4.3.1 ,
Installing the T arget Linux Software), you can run the demos from the
board’s Linux command line. For furt her information on running the
demos from the comman d line, s ee the demo documentation th at is
linked to by the DVSDK release notes.
Note: When you run the demos fr om the comma nd line, make s ure

running. Otherwis e y ou wil l see er ro r me ss ag es rais ed whe n device
drivers fail to open.
Once the EVM board has booted, the disp la y
should show a pi cture of the remote control.
You use the IR remote to control the demos.
The order of the buttons on the actual remote
may be different from the picture; if your
remote looks different, find the buttons with
the same labels on your remote.
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" b utton an d enter "0020 "
as the code (for older remotes shipped
with the kit, the code is "020").
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+0020 code, do a full reset by
removing the batteries, pressing the
Power button for at least a minute, then
reinserting the batteries. Then program
the remote as in Step 3.
