u-boot是否可以在没有linux server的情况下通过网络load要更新的文件呢？ 可以的。我们可以在windows下搭建tftp server，通过u-boot中的tftp来load要更新的文件！做法如下：
1． Unzip tftpd32.400.zip
进入tftpd32.400， 双击tftpd32.exe，
设置Current Directory，选择Browse，找到你要load的文件的目录，
设置 Server interfaces为你的windows的ip地址(10.5.2.249)，
选择Show Dir可以查看tftp server输出的文件
2.重启u-boot
