| 2.1.2.1 Designing Operating System elements
Using the platform builder one can do the following:
a) Create a boot loader.
b) Create a Board Support Package.
c) Create a custom shell.
d) Selecting a configuration for the platform.
Getting Started
To build a platform based on Windows CE operating system the following steps are to be done:
1. Create a platform using Windows CE configuration with a standard development board (SDB).
2. Customize the platform with additional project and catalog features
3. Build the Operating System image to a hardware platform (CEPC). Platform builder includes boot loaders and Board Support Packages for the CEPC and many other hardware development platforms.
4. After refining and debugging platform on hardware development platform, one can adapt it for custom target device.
5. Create a boot loader, OEM adaptation layer and board support package for the specific target device. OEM adaptation layer (OAL) is the layer between KERNEL and TARGET-PLATFORM FIRMWARE.
6. Rebuild the Operating System using new Board Support Package, download it into target device and debug platform.
7. When the platform is complete export a Software Development Kit for the platform. Application developers can import that software development kit into development tools like eMbedded Visual C++.
Platform Creation
Platform creation is done using new platform wizard in which the following steps are done:
a) Select a board support package for the device.
b) Choose and Operating System configuration and variant.
c) Select the features for the platform.
After initial settings have been chosen, the new platform wizard sets up the environment with files that support operating system configuration that was selected. The features included in the platform depend on the operating system configuration which was chosen. There are 13 basic configurations included with Platform Builder and all of them are available from new platform wizard.
After the pictorial view of the whole process, an example of building Operating System image for a Thin Client will be provided.
