摘　　要：VxWork是一种嵌入式实时操作系统,在VxWorks编程与开发工程中,bootrom的设计是一个重要环节。本文在分析VxWorks bootrom的作用和启动过程的基础之上提出一种新的bootrom设计方案,使bootrom具有从主机或Flash装载VxWorks映像的功能,给出了此设计方案的主要代码实现。此方案成功应用于某语音网关中。VxWorks is an embedded RTOS, the design of bootrom is an important step in VxWorks programming and developing, First analyze the function and executing order of VxWorks bootrom, then put forward a design method for bootrom. This method can make bootrom loading VxWorks image from either ftp host or Flash memory. The code of this method was given. And this design was applied successfully in one voice gateway.
