摘　　要：针对传统BDM工具下载或升级应用程序比较麻烦的问题,采用CCP在线更新应用程序,设计一种基于CAN总线的专用BootLoader。介绍BootLoader的设计及CCP在整车控制器端和PC端的实现。实车实验结果证明,BootLoader能够正确引导程序的运行,准确、方便地实现应用程序的下载和升级。Considering inconvenience of downloading or upgrading by Background Debug Mode（BDM） in the traditional ways of the application programs, the special BootLoader which updates application online based on CAN bus and CAN Calibration Protocol（CCP） is designed. Emphasis is paid on the design of BootLoader and the implementation of CCP on between vehicle control unit and personal computer. The vehicle test proves that the BootLoader boots the application accurately, downloads and upgrades correctly and facilly.
