About This Guide
Preface
The DVEVM (Digital Video Eval uat ion Module) is an eval ua tio n pl atf or m
that showcases the DM644x architecture and lets users evaluate the
power and performance of the DM644x as a Multimedia engine. The
intended audience is the user who is developing Linux-based software on
the DM644x ARM core.
The DVEVM does not expose the DSP co re for software development,
but rather treats it as a " black b ox" for running off-the-shel f codecs . Th e
DVSDK upgrade allows you to add the abi lity to dev el op app li cat ion s for
the DSP side. In addition, the DVSDK adds a full Linux license.
This guide gives you overview information about the board and the
software provided w ith the board. It is intended to be used as th e initial
"getting to know you" document for the DVEVM. Other documents
provide more in-depth information. See the DVEVM documentation index
for a complete list of documents that have been included with the product.

Technology and the DM644x
architecture.
This technology brings together system- solu tion
components tailored for efficien t and co mpell ing
digital video and audio.
1-2
The intended audience is a user developing Linux-based software on the
DM644x ARM core. The DVEVM does not expose the DSP core for
software development, but rather treats it as a "black box" for running offthe-shelf codecs. Separate upgrade kits from Texas Instruments will
provide tools and software for DSP development.
1.2 What’s in this Kit?
Your DVEVM kit contains the following hardware items. Section 2.1,
Setting Up the Hardware tells how to connect these components.
❏ DVEVM Board (SDI P/N 702050). This board contains a DaVinci
❏ Hard Disk Drive (Samsung P/N MP0402H). The hard drive provided
❏ CCD Camera (Swann P/N SW-C-C500R). This camera provides

a 5.6" screen and 32 0x240 pixels. Cables and a power supply are
provided. The NTSC ver sion s upp or ts has a 110 VAC power supply.
The PAL version has a 220 VAC power supply.
❏ PC Desktop Microphone (Labtec Verse 333). The microphone
provides a way to capture audio for use by DaVinci applications.
❏ IR Remote Control (Phillips Magnavo x P/N PM4S EFM7N D). This
universal remote control is included to provide a user interface to the
demo applications.
❏ A/V Cables. Cables used to connect the DVEVM board to peripheral
devices and to a host Li nux workstation used for developm ent are
provided in the kit.

Setting Up the Hardware
2.1 Setting U p the Hardware
To set up the hardware provided with the DV EVM, use the steps in th e
sections that foll ow. You may skip sect ions if you do not ne ed to ac cess
a particular peripheral . Fo r ex amp le, if you do no t n eed to use the serial
cable, skip that section.
1) The DVEVM is s ensitive to s tatic 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 vide o cable to the uppe r-right Video Out jac k on
the DVEVM and the LCD display Video Input as shown below.
2-2
See Section A.2, Changing the Video Input/Output Methods for
information about using S-Video or Component video.
Setting Up the Hardware
4) Connect the red and white audio cables to the DVEVM 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 DVEVM 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.2, Changing the Video Input/Output Methods for
information about using S-Video or Component video.

Setting Up the Hardware
7) Connect the microphone to the DVEVM.
8) Connect the power cable to the DVEVM Power Jack on the board. T o
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 DVEVM and to an Ethernet network port.
If you do not connect the board's Ether net controller to a computer
running a DHCP server, booting the board will take several additional
minutes.

Setting Up the Hardware
10) If you pla n to use th e UART port for a co nsole windo w, connect the
RS232 null modem cable to the DVEVM UART port and the a CO M
port on your host Linux worksta tion. See Section 2.2 , Conn ec ting t o
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) Plug in the DVEVM boar d to a power supply.
14) Power on the LCD display.
15) Power on the DVEVM board.
16) The ini tial screen of the demo softwa re should be d isplayed on th e
LCD display. Use the IR remote to run the softwar e as desc ribed in
Chapter 3.
Note that there will be a DHCP-related de lay if there is no network
connection.

Connecting to a Console Window
2.2 Connecting to a Console Window
You can open a console window that al lows you to watch and interrupt
DVEVM boot messages by following these steps:
1) Connect a serial cable between the serial port on the DVEVM and the
serial (COM) port on a PC.
2) Run a HyperTerminal ses sion on the PC and c onfigure it to con nect
to that serial port.
3) When you power on the DVEVM, you will see boot sequence
messages. You can press a key to in terrupt the boot seq uence 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.
