嵌入式调试中的数据获取和错误定位

嵌入式软件系统因其软件相关性和硬件相关性而比常规软件的调试复杂很多，特别是在数据获取和故障定位方面最为突出。从嵌入式软件开发与常规软件开发的异同着手，以该行业实践积累为基础，列出并讨论了一些行之有效的数据获取及错误定位方法，希望能为该领域开发人员提供一点帮助。

The Method of Data Acquisition and Error Locating in Embedded Debugging

The embedded system development come down to software and hardware, so it is more complicated than normal software. Specifically, it＇ s very difficult to get the data from the embedded system. This paper begins with the distinctive of embedded software and normal software, base on the practice, and then lists the methods to get the date from embedded system and to locate error in the embedded program. The target is to provide a litter help for the programmer in flied of embedded system development.
