摘　　要：在基于VxWorks的嵌入式系统开发过程中,设计和调试板卡支持包BSP(Board Support Package)是一个较复杂的问题。在对比常用的bootrom实现的方法后,提出一种支持在系统编程(ISP)的Flash在嵌入式中的应用实现方法,并对该方法的硬件电路设计和器件编程进行较详细说明。该设计方法的引入降低了BSP开发难度,提高开发效率。Aiming at the difficult problem of BSP（Board Support Package）design and debugging, in the process of developing embedded system based on VxWorks,a new method of bootrom implementation is introduced after several methods are compared.And then ,the function ,hardware design and programming of the Flash chip which is used in the new method are described in detail. This method reduces the difficulty of BSP development,and improves the development efficiency.
