基于MPC850 VxWorks系统的BSP设计

摘要

首先介绍嵌入式系统VxWorks及其启动过程；分析了基于MPC 850最小系统的硬件和BSP的执行流程；重点研究了MPC850 BSP的设计与应用程序加载,包括其硬件驱动程序的设计、应用程序加载、建立调试环境和target server的配置等；基于MPC850系统的Vxworks BSP调试平台的实现,对Vxworks上层应用软件和底层硬件驱动的并行开发有着很重要的意义.%First the embedded system VxWorks and starting process are introduced. Based on MPC 850 the system of hardware and BSP execution flow are analysaed. The MPC 850 design of BSP and application program loading are focused on, including its hardware driver design, application program loading, build debugging environment and target server configuration. Realization of Vxworks BSP debug platform on MPC850 system has a very important significance with the VxWorks application software and hardware driver parallel developing.
