摘要
详细介绍了嵌入式Linux(2.4.18)下驱动程序的结构以及设备管理和文件系统的关系。比较深入地介绍了设备驱动程序在Linux下的加载方法,以及各自的优缺点。通过实例代码的解析,得出驱动程序模块的整体框架以及设备驱动的动态挂接、卸载和系统调用的过程,然后介绍了Linux下新驱动的开发。总结了嵌入式Linux驱动程序开发的要点。
This paper introduces the structure of embedded Linux（2.4.18） driver and the relationship between device management and file system. The loading methods of device drivers and their advantages and disadvantages are introduced in greater depth.it gets the structure of driver program module by studying the codes,draws the chart about the loading and unloading of device driver and the process of the system call, and then introduces the development of a device driver.At last,it sums up the key points to develop erabedded Linux driver.
