BSP_NO Environment Variables (Windows Embedded CE 6.0)

1/5/2010

BSP environment variables define the level of optional support available with a hardware platform. There are two categories of variables:

• BSP_NO variables, which you use to define options not supported by a BSP or hardware platform.
  For example, if your target device does not have a USB controller or USB host controller, set BSP_NOUSB = 1 in your target device's Project.bib file. This tells the Platform Builder IDE and the build scripts that USB is not a supported option on your hardware platform.
• BSP variables, which you use to choose a default driver implementation for each class of device. For more information, see BSP Environment Variables.

The environment variables in the following table allow you to set variables to remove support for components. In some cases the Platform.bib file for a target device might need to be updated to support a flag.

In general, you do not need to rebuild your run-time image when updating the setting for a BSP environment variable because these settings are handled during the Make Image phase of the build process.

The following table lists BSP_NO environment variables.
