The MDK-ARM Microcontroller Development Kit supports software development and debugging for ARM-based microcontroller devices. A detailed description of MDK-ARM may be found in Complete User's Guide Selection which may be accessed on the µVision Project Workspace — Books page. The Getting Started User's Guide gives you a good starting point, since it introduces you to MDK-ARM and gives guidelines for programming ARM devices.
