简介

• TFTP(Trivial File Transfer Protocol，简单文本传输协议)，一般用于在局域网内传输升级固件，待更新的文件比较小。默认使用69号端口。
• 使用以太网传输数据
• 使用流程：
  
  • 从机使用69号端口，向服务器发送一个写请求
  • 服务器收到数据后，使用一个随机端口X(4096~65535)，回复数据包
  • 从机以后使用X端口发送数据包。

DFU TFTP命令

开发板

• 通过make menuconfig 使能dfu tftp功能

  root@ubuntu:/opt/u-boot-2017.03# 
  root@ubuntu:/opt/u-boot-2017.03# make menuconfig
  Device Drivers  ---> 
      DFU support  ---> 
           [*] DFU via TFTP 

• 设置环境变量：

  setenv loadaddr 0x43E00000
  setenv filename u-boot.bin
  setenv ipaddr 192.168.2.39
  setenv serverip 192.168.2.40
  setenv updatefile u-boot.bin

主机Ubuntu

• 安装tftp

  root@ubuntu:/opt/u-boot-2017.03# apt-get install tftp-hpa tftpd-hpa

• 修改配置文件

  root@ubuntu:/opt/u-boot-2017.03# cat /etc/default/tftpd-hpa 
  
  # /etc/default/tftpd-hpa
  
  
  TFTP_USERNAME="tftp"
  TFTP_DIRECTORY="/opt/tftpboot"
  TFTP_ADDRESS=":69"
  TFTP_OPTIONS="-l -c -s"
  
  root@ubuntu:/opt/u-boot-2017.03# man tftp
  OPTIONS
       -4     Connect with IPv4 only, even if IPv6 support was compiled in.
  
       -6     Connect with IPv6 only, if compiled in.
  
       -c command
              Execute command as if it had been entered on the tftp prompt.  Must be specified  last  on
              the command line.
  
       -l     Default to literal mode. Used to avoid special processing of ':' in a file name.
  
       -m mode
              Set the default transfer mode to mode.  This is usually used with -c.
  
       -R port:port
              Force the originating port number to be in the specified range of port numbers.
  
       -v     Default to verbose mode.
  
       -V     Print the version number and configuration to standard output, then exit gracefully.

• 重启TFTP服务

  root@ubuntu:/opt/u-boot-2017.03# service tftpd-hpa restart

测试

• 主机端

  root@ubuntu:/opt/u-boot-2017.03# cp u-boot.bin /opt/tftpboot/
