来源：互联网发布：windows代表什么编辑：程序博客网时间：2024/06/07 14:37

安装tftp-server：sudo apt-get install tftpd-hpa
安装tftp-client（根据需要安装）：sudo apt-get install tftp-hpa
配置TFTP服务器：sudo vim /etc/default/tftpd-hpa，修改为如下内容：
TFTP_USERNAME="tftp"
TFTP_DIRECTORY="/home/yuntaohe/work/tftp"
TFTP_ADDRESS="0.0.0.0:69"
TFTP_OPTIONS="-l -c -s"

重新启动TFTP服务：sudo service tftpd-hpa restart
测试TFTP服务器：在u-boot命令行下将内核下载到内存中，ftp 30000000 uImage
dm9000 i/o: 0x20000000, id: 0x90000a46
DM9000: running in 16 bit mode
MAC: 00:0c:29:2a:5c:a5
operating at 100M full duplex mode
Using dm9000 device
TFTP from server 192.168.1.17; our IP address is 192.168.1.6
Filename 'uImage'.

Bytes transferred = 2058416 (1f68b0 hex)

安装NFS服务器：sudo apt-get install nfs-kernel-server
指定NFS目录：sudo vim /etc/exports
/home/yuntaohe/work/nfs/rootfs    *(rw,sync,no_subtree_check,no_root_squash)
启动NFS服务：sudo /etc/init.d/nfs-kernel-server start
设置u-boot启动参数：set bootargs root=/dev/nfs init=/linuxrc nfsroot=192.168.1.17:/home/yuntaohe/work/nfs/rootfs ip=192.168.1.6 console=ttySAC0,115200
启动内核，查看NFS文件系统是否挂载成功：bootm
eth0: link down
IP-Config: Guessing netmask 255.255.255.0
IP-Config: Complete:
     device=eth0, addr=192.168.1.6, mask=255.255.255.0, gw=255.255.255.255,

挂载成功，挂载NFS文件系统：mount -o nolock 192.168.1.17:/home/yuntaohe/work/nfs/rootfs /mnt/nfs
