CM-X300: WinCE: OSDesign Configuration

Installing the Driver Package

• Close the Platform Builder Application if it is open.
• Copy the CM_X300_BSP directory to \WINCE600\Platform\
• Copy the CM_X300 directory to \WINCE600\OSDesigns\
• Launch VS2005 and open \WINCE600\OSDesigns\CM_X300\CM_X300.sln

Building the Platform Project

The CM_X300 Platform Project is used to build CompuLab Windows Embedded CE demo image. It includes many components and is highly recommended as a starting point for a new project. The demo image is relatively large, ~35 MB. Typical Windows CE images for a specific application are much smaller, 8-15 MB.

To build the CM_X300 platform:

• select the Open->Project/Solution command from the File menu of the VS2005 and select the \WINCE600\OSDesigns\CM_X300\CM_X300.sln file.
• Check that the project is configured for Release.
• Perform Rebuild Solution from the Build menu (alternatively, perform Build->Advanced Build Commands->Clean Sysgen ).

The build process takes about 15-20 minutes.

CPU Type

The CM-X300 may be assembled with two CPU types:

• PXA300 - the C624 option
• PXA310 - the C624M option

The default BSP configuration targets the PXA310 CPU.

Choosing CPU Type

The CPU type is defined in CM_X300_BSP.BAT file in the platform directory. Ensure that the BSP_CPU_TYPE setting corresponds with the correct CPU type. Leave the appropriate line without the REM directive:

set BSP_CPU_TYPE=310
REM set BSP_CPU_TYPE=300

Build Options

• Use Build->Advanced Build Commands->Sysgen when adding Platform Builder components (Catalog items) to the project.
• Use Build->Advanced Build Commands->Clean Sysgen when removing Platform Builder components (Catalog items) from the project.
• Use Build->Advanced Build Commands->Build Current BSP and Subprojects when modifying Compulab BSP components that are included in the project or performing changes in the BSP files.
• Use Build->Advanced Build Commands-> Rebuild Build Current BSP and Subprojects when adding/removing Compulab BSP components to/from the project.

Do not use Build->Advanced Build Commands->Build and Sysgen or Build->Advanced Build Commands->Rebuild and Clean Sysgen that perform compilation and sysgen on the entire Platform Builder tree. It is recommended to remove the two commands mentioned above from the menu permanently

Windows CE Image Customization

There are two ways to customize the Windows CE image:

1. Recommended method: Add or remove BSP components from the demo CM_X300 project.
2. Create a new platform project and then manually add all the necessary BSP components as described in the Platform Builder documentation. Refer to Windows CE OSDesign Development page.

BSP customization using batch files

The BSP is fully customizable and allows inclusion/exclusion of each component via BSP_NO environment variables.

To exclude a certain driver, set the BSP_NO environment variables in CM_X300_BSP\CM_X300_BSP_COMMON.bat and rebuild the BSP with Build->Advanced Build Commands->Rebuild Current BSP and Subprojects .

The following table lists the BSP_NO environment variables that can be defined:

Variable	Meaning	Comments
BSP_NOKEYPAD	No Keypad driver and no support for keyboard
BSP_NODISPLAY	No Graphics
BSP_NONAND	No NAND Flash driver
BSP_NOSDHC	No SDIO card driver
BSP_NOWLAN	No WiFi driver
BSP_NOI2C	No I2C driver
BSP_NOUSB20FN	No Usb 2.0 Function driver
BSP_NOUSBFN	No Usb 1.1 Function driver
BSP_NOUSBHOST	No Usb Host driver
BSP_NOAUDIO	No Audio driver
BSP_NOTOUCH	No Touch screen driver
BSP_NOCODEC	No Codec driver	(no Touch and no Audio)
BSP_NOBLUETOOTH	No BlueTooth Driver	No Bluetooth stack as well
BSP_NOLED	No Green led blinking on the module	Saves ~15mA in consumption

Any environment variable defined in CM_X300_BSP\CM_X300_BSP_COMMON.bat will override the variables defined in Platform Builder project

RAM-Based Registry support

The CM-X300 BSP is configured for HIVE-based registry with lazy flushing. The registry hive is located in the system NAND flash. To support a RAM-Based registry, perform the following actions:

• Add the RAM-based Registry component to the project
• Disable the following variables in the CM_X300_BSP\CM_X300_PRODUCTION.bat:

set PRJ_ENABLE_FSREGHIVE=1
set PRJ_ENABLE_REGFLUSH_THREAD=1

• Perform "Clean Sysgen" using Build->Advanced Build Commands->Clean Sysgen

Persistent File System

The CM-X300 BSP is configured to store the root directory in RAM, therefore the root filesystem is not persistent. To make the root and its subsequent folders persistent, change the Catalog item "ROM and RAM File System" to "ROM-Only file System".

Any data saved to a non-persistent location is erased when the device resets. This includes the root directory ("\").

CM-X300 BSP Subprojects

In addition to the drivers supplied with the BSP, there are a few useful utilities distributed as Subprojects. Subprojects allow adding software modules to the build without modifying the BSP source code located in the Platform source tree. There are two Subproject types available with CM_X300_BSP:

• Subprojects that add optional functionality to the BSP are located in the \WINCE600\PLATFORM\CM_X300_BSP\Subprojects directory.

These Subprojects are provided with the source code.

Project Name	Functionality
SetPowerState	Command line utility that controls the system power state and is used for software reboot and suspend support
Regedit	Command line registry editor. Allows remote changes of the device registry via telnet connection.
CoreCon	Executables required for application level debugging over Ethernet in VS2005
AutoLaunch	Executable that should be used for automatic launch of CoreCon (ConmanClient2.exe) at system startup. AutoLaunch.exe verifies IP address availability before loading ConmanClient2.exe. This is required because ConmanClient2 waits for incoming TCP/IP connections when communicating with VS 2005
SysConf	Command line utility for platform debugging
Tools	Command line RTC_CMD utility for RTC driven suspend/resume cycles CLTerm program for COM ports testing
BuildVer	This project adds a text file to the image specifying which revision was used to build the image. It requires a Tortoise Svn client installed on the desktop.

• The Subprojects that add custom applications, control panel applets and registry settings to the demo image are located at \WINCE600\OSDesigns\CM_X300\Subprojects directory.

Project Name	Functionality
CPLApplets\WireLessCPL	Control panel applet that controls the power state (on/off) of wireless devices
CPLApplets\KeypadConfigCPL	Control panel applet that customizes keypad buttons functionality
CPLApplets\BacklightCPL	Control panel applet that controls the LCD backlight level
TCPMP	Open source Media player
TaskManager	Open source Task Manager
KeypadAppLaunch	A utility to capture application launching key presses
LookAndFeel	Look and feel of the demo image (background, theme, sounds, etc.)

KITL Connection

Platform Builder communicates with a device using KITL protocol. For details about KITL refer to Microsoft's KITL Broadcast article.

The following actions should be performed in order to setup a KITL connection between the CM-X300 and Platform Builder 6.0:

1. Ensure that a serial terminal is connected to the CM-X300 as described in Setting up a console
2. Ensure that an Ethernet cable is connected to the CM-X300 platform
3. In Platform Builder, go to Target->Connectivity Options .
   
   
4. Click on Add Device and provide a device name (such as CM-X300).
   
   
5. In Kernel Service Map, select Ethernet for Download and Transport options and KdStub for the Debugger.
6. Press Download settings and at the same time, נoot the target device and press SPACE in the device console to get Eboot main menu.
7. Type "D" to download the image from Platform Builder (results in a broadcast of BOOT ME messages).
8. Platform Builder will show the target device unique name (e.g. CM_X30064242) in the Active Devices area.
   
   
9. Press Transport settings and select Use device name from bootloader.
   
   

Once the connection is configured, download and launch the newly created WinCE image:

1. In Platform Builder Target toolbar, select the configured device and then select Target->Attach Device .
2. Ensure that Eboot is ready for download (i.e. Sends Boot Me messages).

Image Debugging

Platform Debugging with RETAILMSG

Debug messages output to the serial port may be enabled for both Retail and Debug build types.
To enable RETAILMSG output to COM-A serial port, set the "STUART Usage" option to "Debug Serial" in the BSP Configuration menu in Eboot

Platform Debugging over Ethernet

KITL allows platform debugging over Ethernet and enables use of VS2005 Remote Tools. During debug session, KITL redirects all the serial output into VS2005 output window.

• Choose the following platform options to enable platform debugging:
  • Enable kernel debugger.
  • Enable KITL.
• Perform Build->Advanced Build Commands ->Rebuild Current BSP and Subprojects .
• Start the debug session as described in Setup Target for CM_X300 Image Evaluation section.

Run-time image built with the Kernel debugger and KITL dedicates CM-X300 Ethernet port to debug communication. This port cannot be used for application Ethernet traffic. The application Ethernet traffic can be routed through virtual VMINI adapter that should be enabled in Eboot configuration.
