Configuring a Subproject

Configuring a Subproject

Visual Studio provides a number of options in the project properties that you can con­figure to customize the build process for subprojects. To configure these settings, display the Property Pages dialog box for your OS design, as explained earlier in this chapter. You can then find the subproject properties under Subproject Image Settings. For each subproject added or created in the current OS design, you can configure the following parameters:

Exclude From Build Activating this option excludes the subproject from the build process of the OS design, meaning the build engine does not process the source files that belong to the selected subproject.

Exclude From Image Sometimes it can be time-consuming to deploy a run-time image when subprojects change. You have to disconnect from the target platform, rebuild the project, create a new image, reconnect to the target platform, and download the updated image every time a change is made with a subproject. To save time and effort when working on a subproject, you should exclude it from the run-time image by using the Exclude From Image option. In this case, you should also create a way to update the file on the device at run time through KITL, ActiveSync, or any other way you can transfer it to the device.

Always Build And Link As Debug By using this option, you build the subproject in Debug build configuration while your current OS design build process uses the Release configuration. In this way, you can debug the subproject code by using the Kernel Debugger while the operating system is running in the Release version (this option will not automatically enable the Kernel Debugger).

NOTE

Exclusion from the run-time image

When you exclude a subproject from the run-time image, you implicitly exclude the subproject's files from the Nk.bin file that is downloaded to the target device. Instead, Windows Embedded CE accesses the subproject's files on an as-needed basis directly from the Release directory over KITL (when KITL is enabled). This means that you can modify the code in a driver or application subproject without having to redeploy the run-time image. You should only need to verify that the remote device is not currently running the code, and then you can rebuild the code and run it again.
