摘　　要：在基于嵌入式操作系统VxWorks的软件开发过程中,由于人员水平和经验的限制,开发的软件中如果使用了非法指令或堆栈溢出、程序死循环等原因,会造成系统或任务异常,甚至装置死机或重启。根据在实际开发过程中遇到的问题,总结了异常的原因并通过示例给出了分析定位异常问题的方法。During the software design of embedded operation system VxWorks,technicians＂ ability is important,especially the expe-rience of design has a significant effect.If lawless instructions are used,stack overflows or endless loop happens,the system or task would be abnormal,even the program would die or restart.According to the problems met in a project design,this paper summarizes the general causes lead to abnormity and the source of error.It provides a .chance to communicate and takes these problems as an example to show how to locate study the design of embedded operation system VxWorks.
