摘要
板级支持包(BSP)和加载器(BootLoader)是嵌入式技术应用中软硬件结合层面的一个关键环节,它的稳定运行对于整个嵌入式系统来说至关重要,而BSP向上层软件封装底层硬件的多样性也为嵌入式软件的移植提供了不可或缺的便利条件。VxWorks操作系统在现代通信产品嵌入式操作系统市场上占有较大市场份额。文章就VxWorks操作系统的BSP和BootLoader进行了详细的阐述,并介绍了一个修改实例。
Board Support Package (BSP) and BootLoader play a very important role between the software and hardware in embedded system applications. The stability of the whole embedded system lies on the BSP's reliability, and BSP encapsulate d the multiple hardware types for the application software which offers the grea t convenience for the porting work. VxWorks has owned large embedded operating s ystem market in modern communication products. This paper studies BSP and BootLo ader of VxWorks and introduces a concreted sample.
