Hardware Setup

EVM Setup

Set up the EVM as described in the Quick Start Installation Guide supplied with the board (reference 2). The minimum set up required is:

  • Null-modem serial cable connected to the EVM (UART P1) and the development PC
  • Ethernet cross over cable connected to the EVM (ENET P1) and the development PC (or both the EVM and PC connected to a switch via standard Ethernet cables)
  • 5V power supply connected to the EVM (5V IN J6) and the mains supply
  • SW2 BOOT DIP switches set to boot from Serial Flash, switches 1-6 set to OFF, ON, OFF, ON, OFF, OFF

USB Hardware

USB client devices such a mouse, keyboard or flash drive can be attached directly to the EVM via the full speed USB 1.1 port (USB1 J3). To attach client devices via the USB OTG high speed port (USB0 J2) you will require:

  • USB type A socket to micro-A plug (the micro-A plug has the ID pin grounded).

To attach the EVM to a PC (for ActiveSync for example) the OTG port (USB0 J2) can be used with the following cable:

  • USB A plug to micro-B plug

Suitable cables are supplied with the EVM.

Audio Hardware

To use the audio features in the BSP you will require the following hardware connected to the 3.5mm audio jacks:

  • Line in source – LINE IN (P3)
  • Microphone – MIC IN (P4)
  • Headset (high-power) – HP OUT (P5)
  • Headphones / speakers – LINE OUT (P6)

By default the audio driver will use LINE IN and LINE OUT. This can be changed using the wavtest.exe tool.

SD/MMC Cards

The SD card driver in the BSP supports use of SD cards (including high capacity cards) and MMC cards (including MMCplus 8bit cards).

Display Hardware

The BSP supports the following display hardware:

  • Hantronix 24x2 HDM24216L-2-L30S character mode LCD. This LCD module can be connected via the optional UI Board.
  • Sharp TFT-LCD LQ035Q3DG01, available on the optional DA830 UI Board.
  • Sharp TFT-LCD LQ043T1DG01, available on the optional Touch Screen UI Board (for AM1707 EVM only).

Attach the UI Board as described in the documentation supplied with the board.

Note: Only one display device can be supported at one time.

PWM Hardware

The BSP contains a driver and sample application for the Pulse Width Modulator peripheral. The PWM peripheral pins can be accessed via the Audio Expansion connector on the base board.

NAND Hardware

To use the NAND features in the BSP you will need to attach the optional UI Board to the base board. The UI Board NAND socket should be populated with the following NAND chip:

  • Micron Technologies MT29F4G08AAC Flash

Set the SW1 DIP switches on the UI board to ON, OFF, ON, ON.

PRU Soft UART

The BSP supports PRU Soft UART serial ports by attaching the UART expansion board to the base board's 'Audio Expansion' connector.

Building the BSP

Tools Setup

Connect the development PC to the EVM using the serial cable and configure your chosen serial terminal application for 115200 baud, 8 data bits, 1 stop bit, no parity:

AM17x OMAPL137 WinCE 6 0 BSP Quick Start Guide 01.png

IMPORTANT: If you have other development tools installed on your PC check that they have not defined environment variables that may conflict with VS2005. For example, check if MAKEFLAGS or INCLUDES have been defined and un-define them before starting VS2005.

BSP Source Code Installation

Extract the BSP source code from the release installation file. By default, the BSP source code is extracted to C:\TI\BSP_WINCE_ARM9_XX.YY.ZZ\ (where XX.YY.ZZ is the version number)

  Important: If you installed release BSP_WINCE_ARM9_01_10_00, please follow these 2 steps to update the BSP before continuing:

 1. In files 
      PLATFORM\OMAPL138_AM18X\FILES\platform.bib and 
      PLATFORM\OMAPL137_AM17X\FILES\platform.bib
    uncomment the following lines 
        ;IF BSP_PRU
        ;ENDIF BSP_PRU
    to become
        IF BSP_PRU
        ENDIF BSP_PRU

 2. In directories 
      PLATFORM\OMAPL137_AM17X\SRC\DRIVERS\PRU\firmware\ and
      PLATFORM\OMAPL138_AM18X\SRC\DRIVERS\PRU\firmware\
    create an empty "bin" directory   


Move the OS designs and BSP platform files into the relevant locations for Windows Embedded CE 6.0:

 Move extracted folder:  PLATFORM\OMAPL137_AM17X 
    
                   To:  C:\WINCE600\PLATFORM\ 
 Move extracted folder:  PLATFORM\COMMON\SRC\SOC\OMAPL13X_TI_V1 
 
                   To:  C:\WINCE600\PLATFORM\COMMON\SRC\SOC\ 
 Move extracted folders: OSDesigns\OMAPL137_AM17X_SAMPLE 
                        OSDesigns\OMAPL137_AM17X_TI_DEFAULT  
 
                    To: C:\WINCE600\OSDesigns\

Once the BSP is installed the WINCE600 folder tree should look something like this (installed folders arrowed):

BSP Build Notes

Before building and running an OS design there are some checks and configuration changes you may wish to make:

  • TCP/IP settings – The BSP ships with TCP/IP settings for the VMINI and NDIS drivers with DHCP enabled. This can be changed to match your local network configuration, to use static IP addresses for example. See the VMINI and NDIS Ethernet configuration sections below for details of how to change IP settings.
  • Console access – Windows CE does not provide a shell on the UART but you can telnet to the target to get a text console. See the Telnet and FTP section below for details on enabling telnet support.

Building an OS Design

The BSP comes with two OS Designs:

  • OMAPL137_AM17X_SAMPLE – Includes some of the more commonly used CE 6.0 components and support for the peripherals on the EVM.
  • OMAPL137_AM17X _DEMO – Fully featured design including the Silverlight demos, Windows Media Player and Internet Explorer (see the Demo OS Design section below for more details)

In Visual Studio 2005, open the solution file for the OS design you wish to build. For example:

C:\WINCE600\OSDesigns\OMAPL137_AM17X_SAMPLE\
OMAPL137_AM17X_SAMPLE.sln

Before building the BSP the SOC type needs selecting in the catalog. The catalog can be seen by selecting the Catlog Items View tab in VS2005, or selecting View > Other Windows > Catalog Items View. Expand the catalog tree under:

  • Third Party \ BSP \ OMAPL137_AM17X : ARMV4I \ SOC Type

Select the SOC type and clock speed that matches the EVM you will be running the OS image on.

If you have a UI module attached to the EVM you should also select the correct LCD type in the catalog in this location:

  • Third Party \ BSP \ OMAPL137_AM17X : ARMV4I \ Device Drivers \ Display

Select a release build by selecting menu option Build > Configuration Manager and selecting OMAPL137_AM17X ARMV4I Release as the Active solution configuration:

AM17x OMAPL137 WinCE 6 0 BSP Quick Start Guide 03.png

To build the OS design select menu option Build > Rebuild Solution. This will build an EBOOT boot-loader image and a CE 6.0 OS image.

Running OS Designs

This section describes how to boot using the Serial Flash on the EVM base board. For details of booting from NOR, NAND or SD card see the User Guide.

Flashing EBOOT to OMAP-L137 EVM Serial Flash

Note: For flashing the AM1707 EVM see the next section.

It is possible to flash the OMAP-L137 EVM using either Code Composer Studio or the Serial Flash Tool. Using the Serial Flash Tool is the quicker of the two methods if you have a suitable serial port (see details below).

Flashing with CCS

A new EBOOT image can be flashed to the OMAP-L137 EVM using the Code Composer Studio (CCS), which is included with the EVM. Install CCS, EVM Drivers and Target Content as described in the Quick Start Installation Guide supplied with the EVM (reference 2). CCS configuration files and GEL files can also be downloaded here:

12. Start your serial terminal application (115200 baud, 8bit, no parity, 1stop).

13. Power on the EVM and check that the new EBOOT image boots. See the screen shot in the section above.

Configuring EBOOT

Once EBOOT is flashed and running you can configure the bootloader settings. Use your serial terminal application (115200 baud, 8bit, no parity, 1stop) to access the EBOOT menus by pressing SPACE when EBOOT is booting. Use the Network Settings menu to configure the Ethernet download settings:

1. KITL state – enable KITL

2. KITL interrupt mode – check that this is set to interrupt

3. DHCP mode – enable or disable as required

4. IP address and mask – must be on the same subnet as the PC

5. VMINI – enable this if using KITL

6. MAC address – enter the MAC printed on the EVM base board (for BSP 01.00.01 and earlier releases only, for later releases, MAC address is read from EEPROM on board)

A typical configuration used during development is:

 Boot:
   Boot delay .............. 3
   Boot device ............. EMAC
   Debug device ............ EMAC
   Clean Boot .............. No
   Write RAM NK to flash: .. No
   Device ID String ........ (not specified)
   Allow DSP to Boot: ...... No
 Network:
   KITL state .............. enabled
   KITL mode ............... interrupt
   DHCP .................... enabled
   MAC address ............. 00:0e:99:02:fb:de
   IP address .............. 192.168.0.2
   IP mask ................. 255.255.255.0
   IP router ............... 0.0.0.0
   VMINI ................... enabled

When configuration is complete it is recommend that the settings are saved to flash. Setting can be saved using main menu option 6.

Notes:

1. Configuring a MAC address of ff:ff:ff:ff:ff:ff will instruct EBOOT to bypass Ethernet initialisation. This may be used when Ethernet connectivity is not going to be used in EBOOT or Windows CE.

2. It is recommended that you run KITL in interrupt mode as this gives much faster boot and debug response times than polled mode.

Booting the Kernel

Once EBOOT is configured a CE image can be downloaded as follows:

1. Exit the EBOOT menus (main menu option 0) or reset the EVM and allow EBOOT to enter auto-download

2. In VS2005 select menu option Target > Connectivity Options

3. Set Target Device to CE Device

4. Set Download to Ethernet

5. Set Transport to Ethernet

6. Set Debugger to KdStub

7. Click on Core Service Settings and check that Enable KITL on boot device is enabled.

8. Click on Kernel Service Map to return to the download settings.

9. Click on the Download Settings button. You should see the EVM ID listed in the active target devices (if not, power cycle the EVM and check that EBOOT is sending BOOTME packets), click on the EVM entry to select it and return to the connectivity options.

10. The connectivity dialog should now look something like this:

AM17x OMAPL137 WinCE 6 0 BSP Quick Start Guide 09.png

11. Close the connectivity option dialog

12. Select menu option Target > Attach Device

13. VS2005 should open an OS image download dialog and perform the download. If the download does not start power cycle the EVM and check that EBOOT is sending BOOTME packets

14. The CE image should run when download is complete.

Note: The VS2005 image download does not always "sync" with the EVM. If the download is not starting try repeating the steps above (particularly step 9). Restarting VS2005 after changing the settings can also help.

Customising An OS Design

CE 6.0 Catalog

OS designs are customised by selecting components from the CE 6.0 catalog. The catalog can be seen by selecting the Catlog Items View tab in VS2005, or selecting View > Other Windows > Catalog Items View:

AM17x OMAPL137 WinCE 6 0 BSP Quick Start Guide 10.png

The catalog is divided into the following sections:

  • BSP – Contains reference BSPs shipped with CE 6.0. You do not generally need to select anything in this section.
  • Core OS – Contains the standard CE 6.0 components. The CE 6.0 features you wish to use in your OS design are selected from this section.
  • Device Drivers – Contains drivers for some commonly used hardware components.
  • Third Party – Contains BSPs not shipped with CE 6.0, such as the OMAP-L137 BSP.

The sections below describe which catalog components need selecting to support particular features or functionality of the OMAPL137/AM1707 EVM.

OS Build Caveats

When Core OS or Device Drivers catalog selections are changed in an OS design you need to perform a clean and full rebuild. This can be done using the build menu in VS2005 by select Clean Solution followed by Rebuild Solution. This should ensure that the correct image is built.

If you change just OMAPL137_AM17X BSP catalog selections (under Third Party \ BSP \ OMAPL137_AM17X) it is usually possible to rebuild just the BSP (menu option Build > Advanced Build Commands > Rebuild Current BSP and Subprojects). Be warned though that this does not always rebuild every part of the BSP that is affected by the catalog change. If you see unexpected build or run time issues then perform a clean and full rebuild as described above.

BSP Component Conflicts

Due to the extensive SOC pin multiplexing and the EVM design there are some BSP component combinations that are not supported. When customising an OS design the following component conflicts should be observed:

  • Only one display driver can be included in an OS design (the catalog supplied with the BSP enforces this).
  • Cannot include both an LCD driver and the NAND driver.
  • Cannot include both the SDHC driver and the NAND flash driver.

KITL Configuration

KITL over Ethernet is supported by the BSP. Enabling KITL in an OS design enables development tools such as the Target Control and the Kernel Debugger to be used. KITL and the kernel debugger are enabled via the project properties:

Project > Properties > Configuration Properties > Build Options

KITL and the Kernel Debugger can be enabled or disabled for both Debug and Release builds.

Rebuild the BSP after changing build options.

VMINI Network Configuration

The virtual network miniport (VMINI) debug-to-NDIS bridge enables the KITL Ethernet support to be used at the product/OS level (for Winsock TCP/IP, etc).

To use VMINI first enable KITL as described above. Enable VMINI in EBOOT (network settings menu, option 8) and save the settings (main menu, option 6).

In your OS design make sure that SYSGEN_ETHERNET is selected. This appears in the catalog as:

  • Core OS \ CEBASE \ Communication Services and Networking \ Networking - Local Area Network (LAN) \ Wired Local Area Network (802.3, 802.5)

VMINI network settings can be configured in the registry. By default VMINI is configured to use DHCP to obtain an IP address at boot time. Alternatively a static IP address can be configured via the platform.reg file:

C:\WINCE600\PLATFORM\OMAPL137_AM17X\FILES\platform.reg

Find the VMINI TCP/IP section:

[HKEY_LOCAL_MACHINE\Comm\VMINI1\Parms\Tcpip]

Enable/disable DHCP as required and change the IP settings appropriately for your LAN.

NDIS Ethernet Configuration

The NDIS Ethernet driver can be included in an OS Design if KITL is disabled (the VMINI driver can be used when KITL is enabled). KITL can be disabled as described in the ’KITL Configuration’ section above.

The TCP/IP settings for the driver are configured in a similar way to the VMINI settings. Edit the platform.reg file:

C:\WINCE600\PLATFORM\OMAPL137_AM17X\FILES\platform.reg

Find the NDIS driver section:

[HKEY_LOCAL_MACHINE\Comm\EMAC1\Parms\TcpIp]

Change the IP settings appropriately for your LAN.

Enabling the Remote Display

It is possible to attach an LCD display and USB mouse and keyboard but it can also be useful to develop without having to set up this additional hardware. Windows CE 6.0 includes remote display capability that enables the CE screen to be viewed on a PC and for mouse and key presses to be sent from the PC back to the CE device.

There are two different ways to enable this remote display functionality, depending on whether you include a display driver in the OS build or not.

When the OS design does not include the WQVGA display driver the remote display capability can be enabled as follows:

  • Set BSP_DISPLAY_CER=1 in the OMAPL137_AM17X\OMAPL137_AM17X.bat file. This will include a remote display driver in the OS build that will provide a 640x480 colour desktop.

When the OS design does include the WQVGA display driver the remote display capability can be enabled as follows:

  • Navigate to and select the following item in the catalog:
    Core OS \ CEBASE \ Core OS Services \ Debugging Tools \ Remote Display Application

The OS will need TCP/IP communications so configure the VMINI or NDIS networking configuration as described in the sections above. Build the OS image and download it in the normal way.

If using the second option above the remote display application needs starting:

1. With KITL enabled, open the Target > Target Control and start the CERDISP application with the command:
s cerdisp –c

2. Without KITL enabled, telnet to the platform and start the CERDISP application with the command:
start cerdisp –c

To use the remote display capability from the development PC:

1. Run the remote display viewer/host on the PC:
C:\WINCE600\PUBLIC\COMMON\OAK\BIN\I386\cerhost.exe

2. Connect to the EVM (File > Connect)

3. If you do not see the device listed on the connect dialog then check your VMINI settings, DHCP server settings or try a static IP address.

Telnet and FTP Support

Telnet and FTP servers can be added to an OS design by selecting the following items in the catalog:

  • Core OS \ CEBASE \ Communication Services and Networking \ Servers \
  • Telnet Server
  • FTP Server

USB Host Support

To add support for a USB mouse and keyboard select these items in the catalog:

  • Third Party \ BSP \ OMAPL137_AM17X : ARMV4I \ Device Drivers \ USB \ USB Host
  • Core OS \ CEBASE \ Core OS Services \ USB Host Support \
  • USB Host Support
  • USB Human Input Device (HID) Class Driver
  • USB Human Input Device (HID) Class Driver \ USB HID Keyboard and Mouse

If you want to add USB flash drive support add:

  • Core OS \ CEBASE \ Core OS Services \ USB Host Support \ USB Storage Class Driver
  • Core OS \ CEBASE \ File Systems and Data Store \ Storage Manager \ FAT File System

Rebuild the OS design after changing catalog selections.

The mount point for USB mass storage devices can be changed by adding the following registry entry to the OMAPL137_AM17X\FILES\platform.reg file:

[HKEY_LOCAL_MACHINE\System\StorageManager\Profiles\USBHDProfile]

"Folder"="HardDisk"

This will tell the Storage Manager to mount a flash drive in the ’\HardDisk’ folder.

Note: The USB OTG controller in the SOC supports up to 4 IN and 4 OUT USB endpoints. This limits the number of devices that can be used simultaneously. A hub will typically use 1 IN endpoint, a mouse and keyboard 1 IN each and a flash drive 1 IN and 1 OUT. So it may not be possible to use a large number of devices at the same time.

USB Function and ActiveSync Support

To add support for ActiveSync over USB select these items in the catalog:

  • Third Party \ BSP \ OMAPL137_AM17X : ARMV4I \ Device Drivers \ USB \ USB Function
  • Device Drivers \ USB Function \ USB Function Clients \ Serial
  • Core OS \ CEBASE \ Applications - End User \ ActiveSync
  • Core OS \ CEBASE \ Communication Services and Networking \ Networking - WAN \ Dial Up Networking \ Autodial
  • Core OS \ CEBASE \ Communication Services and Networking \ Networking - WAN \ Telephony API (TAPI 2.0)
  • Core OS \ CEBASE \ Shell and User Interface \ Shell \ Graphical Shell \ Standard Shell
  • Core OS \ CEBASE \ Shell and User Interface \ User Interface \ Network User Interface

Rebuild the OS design after changing catalog selections.

The desktop Windows version of ActiveSync can be downloaded from the Microsoft website.

Note: If you wish to run CETK or the remote applications over ActiveSync (rather than a KITL connection) you may need to duplicate the following directory:

C:\Program Files\Common Files\Microsoft Shared\Windows CE Tools\Platman\target\wce600\armV4i

to a directory called "armV4" in the same location.

NAND Support

To add support for the NAND flash and TFAT file systems, select these items in the catalog:

  • Third Party \ BSP \ OMAPL137_AM17X : ARMV4I \ Device Drivers \ Storage Devices \ MT29F4G08AAC NAND Flash
  • Core OS \ CEBASE \ File Systems and Data Store \ Storage Manager \ FAT File System
  • Core OS \ CEBASE \ File Systems and Data Store \ Storage Manager \ Transaction-Safe FAT File System (TFAT)

If your OS design includes a graphical shell you can also include:

  • Core OS \ CEBASE \ File Systems and Data Store \ Storage Manager \ Storage Manager Control Panel Applet

The NAND flash can be partitioned and formatted using the storage manager control panel applet.

The mount point for the NAND flash can be changed by editing the following registry entry in the OMAPL137_AM17X\FILES\platform.reg file:

[HKEY_LOCAL_MACHINE\System\StorageManager\Profiles\NandFlashDisk]

"Folder"="NANDFlash"

This will tell the Storage Manager to mount a the NAND in the ’\NANDFlash’ folder.

UART Support

Support for each of the three serial UART modules can be added by selecting the following items in the catalog:

  • Third Party \ BSP \ OMAPL137_AM17X : ARMV4I \ Device Drivers \ Serial \ UARTx (COMy)

NOTE: The default pin multiplexing settings in the BSP enable only UART 2 to be used.

NOTE: When a serial driver for UART 2 is included in an OS design the OAL debug output is disabled.

NOTE: If the serial driver for UART 1 is included in an OS design then SW5 DIP switch 3 must be set to ON. The driver may fail to initialise without the correct DIP switch setting.

PRU Soft UART Support

Support for up to four Soft UARTs can be added by selecting the following items in the catalog:

  • Third Party \ BSP \ OMAPL137_AM17X : ARMV4I \ Device Drivers \ PRU \ PRU Software UART
  • Third Party \ BSP \ OMAPL137_AM17X : ARMV4I \ Device Drivers \ PRU \ PRU Software UART \ Use McASP1 Serializers
  • Third Party \ BSP \ OMAPL137_AM17X : ARMV4I \ Device Drivers \ Serial \ Soft UARTx (COMy)

Where [Soft UARTx] is one of 0/1/2/3, and [COMy] is one of 4/5/6/7

Note: The PRU Soft UARTs use McASP1 serializers to transmit and receive data on the AM17X / OMAPL-137 EVM.

Note: Only Soft UARTs 0/1/2 are physically connected to the UART Expansion Board.

Note: PWM and Audio drivers must not be selected at the same time as the PRU Soft UART because they all share the same McASP1 pins. The BSP will fail to build if a conflict occurs.

SD/MMC File System Support

To add support for the SD/MMC slot, select these items in the catalog:

  • Third Party \ BSP \ OMAPL137_AM17X : ARMV4I \ Device Drivers \ SD MMC Card \ SD Host Controller
  • Device Drivers \ SD \ SD Bus Driver
  • Core OS \ CEBASE \ File Systems and Data Store \ Storage Manager \
  • exFAT File System
  • FAT File System

If your OS design includes a graphical shell you can also include:

  • Core OS \ CEBASE \ File Systems and Data Store \ Storage Manager \ Storage Manager Control Panel Applet

SD/MMC cards can be partitioned and formatted using the storage manager control panel applet.

The mount point for SD and MMC cards can be changed by adding the following registry entries to the OMAPL137_AM17X\FILES\platform.reg file:

[HKEY_LOCAL_MACHINE\System\StorageManager\Profiles\MMC]

"Folder"="MMCCard"

[HKEY_LOCAL_MACHINE\System\StorageManager\Profiles\SDMemory]

"Folder"="SDCard"

Audio Support

To add support for the audio codec, select these items in the catalog:

  • Third Party \ BSP \ OMAPL137_AM17X : ARMV4I \ Device Drivers \ Audio \ AIC3106 Audio Codec

Support for encoded media file playback (e.g. MP3, WMA) and the CE Media Player can be added to an OS design by selecting these items in the catalogue:

  • Core OS \ CEBASE \ Graphics and Multimedia Technologies \ Media \
  • DirectShow \ DirectShow Core
  • Media Formats \ MPEG-1 Parser/Splitter
  • Audio Codecs and Renderers \ Waveform Audio Renderer
  • WMA and MP3 Local Playback
  • Windows Media Player \ Windows Media Player

The graphical shell also needs to be included in order to use the CE Media Player application:

  • Core OS \ CEBASE \ Shell and User Interface \ Shell \ Graphical Shell \ Standard Shell

Sample Applications

Running Applications

Applications and test utilities can be run from a telnet session or, when KITL is enabled, using the Target Control.

The target control is available from the Target menu. Entering ’?’ into the target control will display help for the commands available. The ’s’ command can be used to run an application. For example, to run the i2ctest utility:

s i2ctest

Any output from the application will appear in the VS2005 "output" window.

Audio Samples

When the audio driver is included in an OS design a number of audio utilites will also be built:

  • wavplay – plays a WAV file passed on command line.
  • wavrec – captures audio to a file. Pass -h for command line help.
  • wavevol – Provides output volume control. Run with no parameters for command line help.
  • wavtest – Switches between LINE IN / MIC IN and LINE OUT / HP OUT

Examples:

s wavevol 80 Set master volume to 80%

s wavrec –r 16000 Record 5secs of 16KHz audio

s wavplay wavrec.wav Play the recorded audio

s wavtest -o 1 –i 1 Switch to MIC IN / HP OUT

WQVGA Display Samples

The LCD display driver supports DirectDraw software rendering and double buffering. The Microsoft DirectDraw samples can be run:

s ddex1

s ddex2

s ddex3

s ddex4

s donuts

You will need a USB keyboard or remote display to use the DirectDraw samples. Note that only the GDI layer is visible on the remote display.

Character Display Samples

The BSP includes a character mode display sample application called ’cldtest’. Run the application with no parameters to get command line help. Example command lines are:

s cldtest -i 9 -a 0 -w "Hello World!"

s cldtest -i b -a 0 -w "Another test"

s cldtest -w " more text" -a 40 -w "Second line"

I2C and SPI Samples

The BSP includes sample applications for the I2C (i2ctest) and SPI (spitest) bus drivers. Run the applications with no parameters to get command line help. Example command lines are:

s i2ctest Get command line help

s i2ctest -t 2 0x21 r 2 Read the PCF8575 settings

s spitest Get command line help

s spitest –b 0 –dlb Run loopback test on bus 0

Demonstration OS Design

Overview

A demonstration OS Design (OMAPL137_AM17X_TI_DEFAULT) is included with the BSP. This OS design includes the following CE 6.0 components:

  • Silverlight sample application
  • Windows Media Player
  • Software audio codecs for WMA and MP3
  • Software video codecs for WMV/MPEG-4 and MPEG-1
  • Streaming media support
  • Internet Explorer 6.0 Sample Browser

The OS design includes an application that launches the Silverlight "Bounce" demo automatically at boot time. Tap/click the screen to exit the demo.

Notes:

1. Internet Explorer 6.0 is a heavyweight application so expect it to run quite slowly.

2. The software video codecs used by Windows Media Player max out the CPU when running so expect playback to be slow and frames to be skipped.

Standalone Boot

The EVM can be configured to boot the demonstration OS design standalone from an SD/MMC card. Perform a Release build of the demo OS design, as described in the sections above. The OS image can then be found in the following location:

C:\WINCE600\OSDesigns\OMAPL137_AM17X_TI_DEFAULT\OMAPL137_AM17X_TI_DEFAULT\RelDir\OMAPL137_AM17X_ARMV4I_Release\NK.nb0

Write the OS image to an SD/MMC card using a PC card reader:

1. Format the SD/MMC card with a FAT32 file system

2. Copy the NK.nb0 file to the SD/MMC card.

3. Delete any file called NK.bin from the SD/MMC card.

Configure EBOOT to boot the image from SD card:

1. Insert the SD/MMC card into the SD slot on the EVM.

2. Power on or reset the EVM. Use your serial terminal application to access the EBOOT menus by pressing SPACE when EBOOT is booting.

3. Enter the Boot Settings menu using option [2]

4. Enter the Boot Device menu using option [2]

5. Set the boot device to "NK from SD" using option [2]

6. Return to the main menu using option [0]

7. Save the settings using option [6]

8. Exit the menus to boot the CE image from the SD/MMC card using option [0]

9. Wait 30 seconds while image is read and booted.
