嵌入式Linux NFS根文件系统的构建及研究

摘要

在嵌入式Linux系统开发过程中,根文件系统是构建嵌入式Linux系统的重要组成部分.为了方便和简化嵌入式Linux开发过程中的调试过程,主要研究了如何使用Busybox构建出基本的嵌入式Linux根文件系统,包括Busybox的配置、编译和安装.在此基础上,进一步构建出基于NFS的嵌入式Linux根文件系统,并给出了启动脚本和配置文件.这种根文件系统可以方便地在线更改、调试程序,降低了嵌入式系统的开发门槛.%In the process of the embedded Linux system development, the root file system is an important part of building the embedded Linux system. In order to facilitate and simplify the debugging phase of embedded Linux development process, this paper mainly researches how to build a basic embedded Linux root file system with Busybox, including the configuration, installation and compilation of Busybox. On this base, the NFS-based embedded Linux root file system was built. The startup script and configuration file are given in this paper. This root file system can be easily changed and debugged online, and reduces the threshold of embedded systems development.
