Setting Up the Hardware
2.1 Setting U p the Hardware
To set up the hardware prov ided wit h the DVEVM k it, us e the steps that
follow. You may skip steps if you do not need to access a particular
peripheral. For examp le, if you do not ne ed to use the s erial cabl e, skip
that step.
For reference, the num bers in the following photo of the DM357 EV M
target board correspond to the steps in the procedure.

prevent damaging the board. Be sure to connect
communication cables before applying power to any
equipment.

Setting Up the Hardware
1) On the S3 mini-dip switch, verify that positions 1 through 4 are
configured to boot from on-board NAND as in the following figu re,

6) (Optional) If you will be using an Ethernet connection, connect the
provided Ethernet cabl e to the E the rn et p ort (P 2) on the E V M bo ar d
and to an Ethernet network port.
Note: If you do not connect the board’s Ethernet controller to a
computer running a DHCP server, booting the board may take
several additional minutes.
7) Connect the provi ded power cable t o the DVEVM power jack (J14)
on the board. To be ESD safe, plug in the other end of the cable only
after you have connected the power cord to the board.
8) Power on the EVM board by flippi ng the powe r switc h (SW1).

9) Y ou should see the initial screen of the demo software on your video
display. Use the IR remote to run the software as described in
Chapter 3.
2.2 Connecting to a Console Window
You can open a console windo w that allows you to watch and interrupt
EVM boot messages by following these steps:
1) Connect a seria l cable betwee n the serial port on the EVM and the
serial port (for example, COM1) on a PC.
2) Run a terminal session (such as Minicom on Linux or HyperTerminal
on Windows) on the wor kstation and configure i t to connect to that
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 NAND flash 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 2.1)
To abort the standard boo t, press any key in the console wi ndow (see
Section 2.2). Also see Section A.4, Alternate Boot Methods if you want to
change the boot configuration.
Note: It is best to power down the board cleanly in order to reboot,
rather than using the reset button or power switch. We recommend
that you use the shutdown command to shu t down the operating
system and unmount the file system b efore removing po wer from
the board. This will help p revent cor ruption of the flash-bas ed root
file system.
3.2 Starting the Standal one Demos
When you connect the EVM hardware, the pre-loaded examples run
automatically on your video 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 n o c onn ectio n to a workstation 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
