How to Create a Run-Time Image with Multiple XIP Regions (Windows Embedded CE 6.0)
1/6/2010
Windows Embedded CE enables you to create multiple execute-in-place (XIP) regions in a single run-time image. XIP regions are areas in which an application can run code directly from ROM, rather than having to load it from RAM.
With a multi-region run-time image, you have finer control over the run-time image layout, you can control region updates, and you can decide on a per-region basis how the OS accesss that region when it pages its parts at run time.
Hardware and Software Requirements
This document makes the following assumptions:
- Your Platform Builder installation includes CEPC x86 and Emulator x86 board support packages (BSPs).
- You have a CEPC already configured. For more information, see How to Set Up a CEPC and How to Use the IDE to Create, Customize, and Build a Run-Time Image.
You can track your progress in the following table.
| Step | Topic |
|---|---|
1. Create a base OS design for your run-time image with multiple XIP regions. |

2. Modify the Config.bib and Platform.bib binary image-builder files to add settings and files that are required to build a run-time image with multiple XIP regions. |
|
3. Build the run-time image, and open a workspace with multiple XIP regions from which you can download your run-time image to the CEPC. |

4. Configure an Ethernet connection for downloading your run-time image to the CEPC. In the Target Connectivity Options dialog box, under KITL Settings, clear the Enable access to desktop files checkbox. |
|
5. Download your run-time image to the CEPC. |
|
6. Test your run-time image with multiple XIP regions by verifying that all of the modules that you have placed in a separate region load correctly. |
