2 Application Baseboard
2.1 Application Baseboard Features Diagram
2.2 DIP Switches
There are two 8-position DIP switches located on the application baseboard at reference
designators S2 and S7. By default, all of the switches are set to the “OFF” position.
The S2 DIP switch is reserved for user application general purpose. The S7 DIP switch controls
the processor’s boot mode and several FET muxes on the baseboard. Table 2.1 describes the
function of each switch.

3 Removing the AM1808 SOM-M1
The following steps will walk you through removing the AM1808 SOM-M1 from the eXperimenter
Kit baseboard and then reconnecting it. This may be necessary for troubleshooting purposes or if
you purchase a different AM1808 SOM-M1 that is compatible with your eXperimenter Kit.
1. IMPORTANT NOTE: A nylon screw keeps the LCD fastened to the baseboard during
shipment. Remove this screw from the bottom side of the baseboard before attempting
to eject the LCD.
Eject the 4.3” LCD by pulling the LCD ejector levers away from the LCD. Remove the LCD
from the baseboard and set aside.
2. Taking care not to bend the PCB, remove the AM1808 SOM-M1 by applying even pressure
beneath the PCB edges and pulling up.

3. To connect the AM1808 SOM-M1, align the SOM over the three board-to-board connectors.
Using even pressure, press straight down over the connectors to mate boards. Visually verify
that all three connectors have fully mated.
4. Connect the 4.3” LCD by inserting into the baseboard LCD connector and pushing down over
the connector until the LCD ejector levers move to a vertical position. CAUTION: The solder
points on the LCD connector PCB may be sharp; use caution when connecting the LCD.
4 Connect Blackhawk Emulator
The AM1808 eXperimenter Kit includes a Blackhawk™ USB100v2 JTAG emulator.
1. IMPORTANT NOTE: A nylon screw keeps the LCD fastened to the baseboard during
shipment. Remove this screw from the bottom side of the baseboard before attempting
to eject the LCD.
If the 4.3” LCD in connected to the application baseboard, it must be removed prior to
connecting the Blackhawk emulator. Pull back on the ejector levers until the LCD board
connector moves up and disengages from the baseboard 60-pin LCD connector.
2. The Blackhawk emulator connects to the JTAG 20-pin header for ARM core on the
application baseboard. See Section 2.1 for diagram pointing to the location of this header.
3. Position the emulator so the ribbon cable extends away from the application baseboard. See
figure below.
4. Make sure all of the header pins line up with their respective holes on the PCB connector.
Press straight-down on the PCB until the header and connector fully mate. (To assist with
proper positioning of the emulator 20-pin connector, silkscreen printing on the bottom side of
the PCB calls out the location of pins 1, 2, 19, and 20; these can be used to verify the
connector holes matchup with their respective header pins on the application baseboard.)

5. The 4.3” LCD can now be reconnected to the application baseboard.
5 Installing Code Composer Studio
The Zoom AM1808 eXperimenter Kit includes a software DVD containing Code Composer Studio
(CCStudio).
1. Insert the Code Composer Studio v4 software DVD into your host PC.
2. Navigate to the DVD drive and open the files on the CCStudio DVD. Double-click on
setup_CCS_4.2.x.xxxxx.exe and a splash screen similar to the image below will appear. Click
the Next button.
3. Follow the on screen instructions until you arrive at the screen for Product Configuration,
select Platinum Edition.
4. On the next screen, leave the default ISA items checked. Click the Next button.
5. Leave the default Component items checked. Click the Next button.

6. Click the Next button to start copying files.
7. Wait for CCStudio to finish installing; this process can take some time, so please be patient.
8. Click the Finish button when the installation is complete. You may eject the CCStudio DVD
at this time.
6 Running Board Support Library (BSL) Sample Programs
The BSL sample programs are included to test the different features of the development kit and
diagnose any potential problems. In order to run these tests, you first have to connect your
development kit to a PC.
6.1 Connect eXperimenter Kit to Host PC
To communicate with the AM1808 eXperimenter Kit using CCStudio, you will need to connect the
included USB A to mini-B cable to the USB mini-B connector on the Blackhawk emulator (see
Section 4) and a USB A port on the host PC.
As soon as the USB cable connects to your host PC, Windows should automatically recognize
that new hardware has been connected and install the necessary drivers. Power on your AM1808
eXperimenter Kit, move the S7 DIP switches 7 and 8 to the on position, and continue with the
next section.
6.2 Copy BSL Files to PC
The Windows CE SD card included with the AM1808 eXperimenter Kit contains the GEL and BSL
files. These files need to be copied to your host PC.
1. Insert the SD card into the USB card reader and insert the card reader into a USB port on
your host PC.
2. Navigate into the SD card and locate the BSL files directory.
3. Extract the ZIP archive and save the files to your host PC. (NOTE:The files may be placed
anywhere on your host PC; however, the original file structure must remain intact.)
4. For the instructions in this User Guide, it is assumed the files were copied to the root C:\
drive. For example:
C:\AM1808_BSL
6.3 Launch Code Composer Studio
1. Launch Code Composer Studio by selecting Start Menu > All Programs > Texas
Instruments > Code Composer Studio v4.2.0 > Code Composer Studio v4.

2. Select a workspace location and then click the OK button.
3. CCStudio will finish launching and a Welcome to Code Composer Studio window will open.
(NOTE: If you do not have the latest Adobe Flash Player installed on your machine, you will
be prompted to install. This is required for proper viewing of the Code Composer Studio
Welcome screen.)
4. If you do not have a license, select the Activate a License option and click the Use Free
Limited License button. (NOTE: If you do not have an active Internet connection, you can
select to Evaluate Code Composer Studio for 30 days. At any time during that period, you
can change to the Free Limited License by selecting Help > License Options... from the
CCStudio menu bar and then following the onscreen instructions.)

5. You will be redirected to TI’s website to login in with your myTI.com account. Follow all the
online instructions. After completing the online instructions, you will receive an email
containing an attachment that is your license file.
6. Save the license file to your host PC, then return to the Welcome to Code Composer Studio
window and under Step 2 - Install License File, browse to where you saved the license file.
Click the OK button.

7. You will then be presented with the Code Composer Studio Welcome screen. Click on the
cube in the upper right-hand corner to go to the CCStudio workbench.
8. The CCStudio workbench will then appear.
6.4 Run Sample Test
As an example, we will run one feature test. In order to run a test program, you will have to select
the program, compile (or build) the program, and then load the compiled program. The following
steps will walk you through that process.

8. After the test finishes loading, you will see a message in the Console window stating
“Memory Map Setup Complete.”
9. To run the program, select Target > Run from the menu bar. (NOTE: If you receive a
message stating “Error during: Execution, Initialization, Control,” click Cancel, select Target
> Terminate All from the menu bar, press the reset button on the baseboard, and repeat
steps 7-9.)

10. The Console window provides a brief description of the test. If you move any of the S2 DIP
switches, output text will print the switch that was moved and its new position (ON or OFF)
and USER LED1 or USER LED2 will turn on or off in relation to the DIP switch position.
The steps in this section can be repeated to run any of the other tests for your eXperimenter Kit.
(NOTE: All of the tests in the “experimenter” folder can be run on both the AM1808 EVM and
eXperimenter Kit; the tests in the “evm” folder can only be run on the AM1808 EVM.)
