Setting Up the Hardware
2.1 Settin g U p the Hardware
To set up the hardwa re pr ovided wit h the DVE VM kit, use the steps tha t
follow. You may skip steps if you do not need to access a particular
peripheral. For examp le, if you do not need to use the serial ca ble, skip
that step.
For reference, the num bers in the following photo of the DM357 E VM
target board correspond to the steps in the procedure.

Important: The EVM board is sensitive to static
discharges. Use a g rounding strap or other de vice to
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 f igure,
where the black rectangle is the switch location.

Also on the S3 mini-dip switch, verify that position 10 selects the
correct video format— NTSC or PAL . The following diagram shows
the switch in the NTSC setting.
2) Connect an audio speaker to Stereo Line Out (P5) and an audio
source to Stereo Line In (P3).

6) (Optional) If you wil l be using an Ethernet connection, connect the
provided Ethernet c abl e to the E the rnet p or t (P2) on the E V M bo ard
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 p rovided power cable t o the DVEVM powe r jack (J14)
on the board. T o 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 fli pping the powe r swi tch (SW 1).

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 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: No ne
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 sta ndard 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.
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 t he shutdown command to s hut down the operating
system and unmo unt the file syste m before removing power from
the board. This will hel p prevent c orruption of the flash-b ased root
file system.
3.2 Starting the Standalone 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 wi th n o conn ec tio n to a wo r kstation in the defa ult boo t
configuration. This is the mode documented in the rest of this
chapter.
