VxWorks应用开发中的异常分析及处理方法

Abnormal Analysis and Processing Method in VxWorks Application Development

在嵌入式实时软件开发过程中,通常会由于非法指针、代码段破坏、堆栈溢出、内存泄漏、任务死循环等原因导致系统异常,并且难以定位异常原因。文章基于嵌入式实时操作系统VxWorks,对开发过程中常见的异常进行分析,并给出了异常故障记录、异常定位以及异常解决等方法。

In the development of embedded realtime application, there are many reasons of this such as invalid point, code seg- ment damage, stack overflow, memory leakage, dead loop task. If it happens, the system would be abnormal and very difficult to debug for developer. This paper analyzes the general exceptions lead to abnormity base on VxWorks and provides the exception fault logging, locate the faults, and abnormal solutions method.
