How to Configure and Build a Run-Time Image for a CEPC (Windows Embedded CE 6.0)

1/5/2010

Before you build a run-time image for a Windows Embedded CE PC-based platform (CEPC), you might have to change settings in the Platform Builder IDE. Whether you do depends on your CEPC hardware requirements and your development goals. Also, you might have to configure your run-time image to reside in a larger amount of RAM than the default amount of 28 MB specified the %_WINCEROOT%\PLATFORM\CEPC\FILES\Config.bib file. If you want to support kernel debugging, profiling, or other build options, you must specify these options in the IDE.

Step Topic

1. Use the Windows Embedded CE OS Design Wizard to select a design template and the initial components for your OS design.

2. Customize your OS design by selecting items from the Catalog or deleting items from your OS design.

3. Based on your development goals, configure the settings for your run-time image in the <OSDesignName> Properties dialog box.

4. Choose a Debug or Release configuration to target when Platform Builder builds the OS design into a run-time image.

To use the kernel debugger, make sure that support for the kernel debugger is enabled.

5. Decide whether to enable kernel independent transport layer (KITL) for debugging activities.

6. Check the dependencies of the Catalog items in your OS design.

  1. In the Catalog Items View, right-click a Catalog item and select Show Dependencies.
  2. In the Catalog Items Dependencies window, Expand Depends On node to discover which Catalog items that the selected item must include as dependencies. Then, expand Dependency Of to discover which Catalog items must include the selected item as a dependency.

7. Modify the MEMORY section in the %WINCEROOT_%\PLATFORM\CEPC\FILES\Config.bib file by setting the environment variable that specifies the amount of RAM on your CEPC hardware or the amount of RAM you want to simulate.

By default, the %WINCEROOT\PLATFORM\CEPC\FILES\Config.bib file specifies 28 MB of RAM, and then the OEM Adaptation Layer (OAL) scans for additional memory at run time, for up to a total of 64 MB.

  • If your CEPC has 16 MB of RAM, or you want to simulate 16 MB of RAM, set the IMGRAM16 environment variable.
  • If your CEPC has 32 MB of RAM, or you want to simulate 32 MB of RAM, set the IMGRAM32 environment variable.
  • If your CEPC has 64 MB of RAM, or if you want to simulate 64 MB of RAM, from the Project menu, choose Properties. Then, select the Build Options node, select Run-time image can be larger than 32 MB (IMGRAM64=1).
  • If your CEPC has 128 MB of RAM, or if you want to simulate 128 MB of RAM, set the IMGRAM128 environment variable.

8. Build the OS design into a run-time image.

9. In the Output window, on the Output tab, verify that your build contains no errors.
