2.1 Processor Module SW1
The DIP switch on the processor module controls various signal routing choices. Please be sure it
matches the above diagram for normal operation. SW1 must be configured differently to use a JTAG
emulator with the EVM. Consult the Hardware User’s Guide for more detail.The DIP switch on the
processor module controls various signal routing choices. Please be sure it matches the above diagram
for normal operation. SW1 must be configured differently to use a JTAG emulator with the EVM. Consult
the Hardware User’s Guide for more detail.
2.2 Main Board SW4
The main board’s SW4 DIP switch controls the boot mode of OMAP3 processor. The default setting
shown above will try to boot from UART3. If no response is seen in a short time (< 1 S) the processor will
attempt to boot from the attached flash memory.
Consult the Hardware User’s Guide for details and for other settings.
Please ensure to match the numbers in the diagram to the numbers on the DIP switch as the orientation
of the switch may not be what you expect. It is not guaranteed that the switch settings below would work
for all the EVM boards. For more information on the switch settings for selecting the boot modes, refer to
the user guide in the OMAP3503 SDK installation under /home/<useracct>/OMAP35x-PSP-SDK-

Note: Switch OFF == logic 1 and Switch ON == logic 0.
2.3 J8
Jumper J8 controls which OMAP UART is connected to the UART1/2 board connector. Make sure it
selects UART1 as shown. All other jumpers on the board are normally unpopulated.
2.4 UART1
Connect the supplied serial cable to the UART-1/2 DB-9 connector. The other end of the serial port
should be connected to a PC. The PC should run a terminal emulator such as HyperTerm or TeraTerm
for Windows or minicom or gtkterm for Linux. The terminal program should be set for 115200 Baud rate, 8
data bits, no parity, and all flow control off.
During boot and while the demo application is running, status messages will appear on the serial port
connection.
2.5 Ethernet
Connect an Ethernet cable to the RJ-45 jack on the board. It is suggested that initially the Ethernet be
used on a closed private network with static IP addresses assigned. DHCP can be used once the setup is
complete. The Ethernet connection is not used during the demo but is used for TFTP transfers of
software and can be used for Telnet and NFS.
2.6 Audio Out
P9 can be connected to powered PC style speakers or to headphones (not supplied).
Although the demo will run without audio connections, they are used during the audio playback portion of
the demo.
2.7 Audio In
P11 can be connected to an audio source such as the line out jack of a PC sound card or the headphone
jack of an MP3 player.
As with the audio out, the demo will function without this connection.
2.8 Power Selection Switch
SW2 on the Main board selects between battery and DC power in. The DVEVM comes with a DC power
source that should be used. This switch should be set so the switch body is closer to the DC label on the
board.

Document OMAP35x DVEVM Getting Started Guide Rev 3.0
Document Number SPRUFZ7 Date Sept 23, 2009
18
Note: This switch is not intended to be a power switch. It should be set to DC and left in that position. An
external switch can be used to control the AC input to the power adapter if an adapter is desired.
2.9 Power Cable
After all other steps are performed, ensure the power adapter is unplugged and then insert the adapter’s
DC plug into P19. Finally the power adapter can be plugged into the AC wall source.
2.10 Setup Terminal Program
A serial port terminal program should be used to communicate with the OMAP35x EVM board’s serial port
console. For Windows users HyperTerm or TeraTerm are recommended. For Linux users Minicom is
recommended. In any case, the serial modem settings are the same:
•Bits per second: 115200
•Data bits: 8
•Parity: None
•Stop bits: 1
•Flow control: none
Once the settings are in place, connect to the board using the serial terminal program and power up the
board by plugging in the AC adapter. The U-Boot start up screen will appear. If not interrupted, the EVM
will continue to boot into a Linux command prompt.
To send text file scripts to the EVM a per-line delay of approximately 100 ms must be configured into the
terminal program.
The following sections give specific setup guidance for three serial terminal programs.
2.10.1 HyperTerm Setup
HyperTerminal comes with Windows XP and can be found in Start Menu -> All Programs -> Accessories -
> Communication -> HyperTerminal. After initial dialogs, create a new connection and select the
appropriate COMn port. The next dialog will allow you to set the communication parameters as described
above. Finally set the line delay by choosing File -> Properties -> Setting Tab -> ASCII Setup button ->
and enter 100 in the Line Delay box. Press OK.
2.10.2 TeraTerm Setup
TeraTerm is a commonly used terminal emulator for Windows. It can be found at the following URL:
http://hp.vector.co.jp/authors/VA002416/teraterm.html
When you start TeraTerm it will normally ask you for TCP or COM port. Select the correct COM port.
Serial port settings can be found in Setup -> Serial Port …. Set the serial port as described above and
enter 100 in the msec/line entry. You can save your settings using Setup -> Save Settings …. If you
save to the teraterm.ini file in the TeraTerm install directory you will set the startup options for the
program.
2.10.3 Minicom Setup
In order to run minicom as a regular user, make sure the user is in the proper group, allowed to create
lock files in /var/lock (the default location), which is usually the "uucp" or "dialup" group.

Document OMAP35x DVEVM Getting Started Guide Rev 3.0
Document Number SPRUFZ7 Date Sept 23, 2009
19
To create a new configuration for the serial port, run minicom as follows under root:
# minicom -c on -s
Command line options used above enable color (-c on) and start the setup procedure (-s).
From the setup menu configure the serial port name and parameters - "Serial port setup" -> "A" for the
"Serial Device" (/dev/ttyS0 or /dev/ttyS1) and "E" for the "Bps/Par/Bits" setup, which is "115200 8N1" by
default.
You may want to remove the Init (A) and Reset (B) modem strings under "Modem and dialing" menu.
Once ready, save the configuration either into default location (Save setup as dfl) or otherwise into a
separate name (Save setup as...), in which case you will have to specify the non-default configuration
every time you start minicom.
Now, you can start minicom as a regular user:
$ minicom -c on
And with the non-default configuration, assuming you saved it under "ttyS0" name:
$ minicom -c on ttyS0
In order to send multi-line scripts to the target, set the "Newline delay (ms)" under "Terminal settings"
(Alt+T) to 99. This step must be completed each time before sending a multi-line text file.

3 Running the Demonstration Software
This chapter explains how to run the software demos provided with the OMAP35x DVEVM.
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.
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.
The out-of-the-box boot parameters are listed in Section Booting From Flash using Board’s NAND Flash
File System The following are alternate ways you may want to boot the board:
¾TFTP boot with NAND flash file system (Booting via TFTP Using Board’s NAND Flash File
System)
¾Flash boot with NFS file system (Booting from Flash Using NFS File System)
¾TFTP boot with NFS file system (Booting via TFTP using NFS file system)
To abort the standard boot, press any key in the console window (see Section 2.10 on setting up the
console window). Also see Section (Alternate Boot Methods) if you want to change the boot configuration.
NOTE
