The board support package (BSP) is the support code for a given hardware platform or board that helps in basic initialization at power-up and helps software applications to be run on top of it. It can be specific to some operating systems with boot loader and device drivers.
Tip
To reset the BSP source, double-click platform.prj, select a BSP in a domain, and click Reset BSP Source. This action only resets the source files while settings are not touched. To change the target domain after application project creation, double-click the project.prj file in Explorer view. In the Application Project Settings, select Domain → Domain change option → Drop-down Domain, then select the available domains for this application.
