一、Ubuntu端TFTP服務器配置：
-
Ubuntu下使用以下命令安裝TFTP服務：（安裝 tftp-hpa 和 tftpd-hpa）
sudo apt-get install tftp-hpa tftpd-hpa
- 創建一個TFTP文件夾
mkdir /home/pjw/linux/tftpboot
- 給予TFTP目錄可讀可寫可執行權限（文件或文件夾給權限後變爲綠色）
chmod 777 /home/pjw/linux/tftpboot
- 安裝xinetd
sudo apt-get install xinetd
- 配置xinetd
新建並編輯文件/etc/xinetd.d/tftp
sudo vi /etc/xinetd.d/tftp
輸入如下內容：
server tftp
{
socket_type = dgram
protocol = udp
wait = yes
user = root
server = /usr/sbin/in.tftpd
server_args = -s /home/pjw/linux/tftpboot/
disable = no
per_source = 11
cps = 100 2
flags = IPv4
}
-
啓動 tftp 服務
sudo service tftpd-hpa start
- 編輯/etc/default/tftpd-hpa 文件
sudo vi /etc/default/tftpd-hpa
修改爲以下內容：
# /etc/default/tftpd-hpa
TFTP_USERNAME="tftp"
TFTP_DIRECTORY="/home/pjw/linux/tftpboot"
TFTP_ADDRESS=":69"
TFTP_OPTIONS="-l -c -s"
- 重啓TFTP服務器
sudo service tftpd-hpa restart
二、TFTP服務使用：
- 將 zImage 鏡像文件拷貝到 tftpboot 文件夾 中，並且給予 zImage 相應的權限
cp zImage /home/pjw/linux/tftpboot/
cd /home/pjw/linux/tftpboot/
chmod 777 zImage
uboot 中的 tftp 命令格式如下：
#tftpboot DRAM中的存放地址 要從Ubuntu中下載的文件
tftpboot [loadAddress] [[hostIPaddr:]bootfilename]
- 映像文件燒錄：
