希望大家在此帖把在学习2410过程中关于ARM Linux的一些笔记写/贴出来，也希望有兴趣的朋友积极参与。<br />作为开贴，我转几篇我在chinaunix的关于2410入门的blog<br /><br /><a href="http://blog.chinaunix.net/u/27204/showart_433964.html" target=_blank>http://blog.chinaunix.net/u/27204/showart_433964.html</a><br />QT2410入门实践02 --- PC（宿主机）环境安装及配置<br /><br /><br />2007/10/21<br />===================================================================================================<br />Host OS install and environment build<br />===================================================================================================<br />1. Linux host OS: Ubuntu-7.10<br /><br />2. On linux host, execute command after installed<br />$sudo apt-get upgrade <br />$sudo apt-get update<br /><br />3.

Install nfs<br />$sudo apt-get install nfs-kernel-server <br />$edit /etc/exports, add /opt/nfs *(sync,rw) <br />$sudo /etc/init.d/nfs-kernel-server restart<br /><br />5. Install tftp<br />1) Install tftpd and related packages.<br />$sudo apt-get install xinetd tftpd tftp<br />2) Create /etc/xinetd.d/tftp and put this entry:<br />service tftp<br />{<br />protocol = udp<br />port = 69<br />socket_type = dgram<br />wait = yes<br />user = nobody<br />server = /usr/sbin/in.tftpd<br />server_args = /tftpboot<br />disable = no<br />}<br />3) Make /tftpboot directory<br />$sudo mkdir /tftpboot<br />$sudo chmod -R 777 /tftpboot<br />$sudo chown -R nobody /tftpboot<br />4) Start tftpd through xinetd<br />$sudo /etc/init.d/xinetd start<br /><br /><br /><br /><a href="http://blog.chinaunix.net/u/27204/showart_433982.html" target=_blank>http://blog.chinaunix.net/u/27204/showart_433982.html</a><br />QT2410入门实践03 ---交叉编译工具（for ARM）及rootfs（for NFS）的制作<br /><br /><br />===================================================================================================<br />Building buildroot-20071126.tar.bz2<br />===================================================================================================<br />1.

Done! That's all. ARM Linux cross toolchain and rootfs is completed until now!<br /><br />9。/opt/buildroot/project_build_arm/uclibc/root/ is a completed rootfs for NFS。<br /><br /><br />最后对该帖有几点建议：<br />1。欢迎对该贴的相关内容进行讨论<br />2。不赞成对该帖的好坏进行讨论，不欢迎对该帖进行评价。个人认为这样是在浪费大家的时间。<br /><br /> 相关链接:<a href='http://blog.chinaunix.net/u/27204/showart_433964.html'>http://blog.chinaunix.net/u/27204/showart_433964.html</a> |
