自从上次捣鼓了SD卡烧录系统后，就继续按照手册进行下一步——TFTP方式烧录，本人使用的Ubuntu 12.04 系统，基本上是按照手册操作，遇到了一些问题，索性有万能的google，这里列出一些跟手册有出入的地方：
首先是TFTP的搭建，因为我用的不是fedora系统，所有有些不同：
sudo apt-get install tftp-hpa tftpd-hpa xinetd
在根目录下创建文件夹/tftpboot/
修改目录权限chmod -R 777 /tftpboot/
修改tftp配置文件，如果没有就创建
#vim /etc/xinetd.d/tftp
service tftp
      {
         disable       = no
         socket_type    = dgram
         protocol       = udp
         wait          = yes
         user          = root
         server       = /usr/sbin/in.tftpd
         server_args    = -s /tftpboot/
         source       = 11
         cps          = 100 2
         flags =IPv4
      }
修改inetd.conf文件
# vim /etc/inetd.conf
tftp  dgram udp wait nobody /usr/sbin/tcpd
/usr/sbin/in.tftpd /tftpboot/
其中/tftpboot/root为 tftp共享目录
修改tftpd-hpa文件
# vim /etc/default/tftpd-hpa
#RUN_DAEMON="no"
#OPTIONS="-s /tftpboot/root -c -p -U tftpd"
TFTP_USERNAME="tftp"
TFTP_DIRECTORY="/tftpboot/root"
TFTP_ADDRESS="0.0.0.0:69"
TFTP_OPTIONS="-l -c -s"
这样就算装好了，对了，不要忘了重新启动tftp服务。service tftpd-hpa restart

在/tftp目录下创建任意文件：123.txt
tftp localhost 进入tftp命令行
get 123.txt
看是否下载成功

下面是重启内容：
