tftp 烧写镜像名字规定与对应命令

由于 uboot 的一键式 tftp 下载命令的限制(即只能使用固定的文件名) ，所以，为了使用一键式菜单，

作出如下规定：

uboot 镜像必须命名为：u-boot.bin—命令“1”

Linux 内核镜像必须命名为：zImage.bin—命令“3”

文件系统镜像必须命名为：root.ubi—命令“5”

logo 镜像必须命名为：logo.bin—命令“4”

Ø 将改好名字的镜像放到刚刚设置好的“OutPut(“K:imagestftp”) ”目录下：

说明：一定要放到设置 tftp 代理软件“Output”页所指定的输出文件的路径下，因为该软件发送文件时会。

ping failed; host 192.168.1.8 is not alive ;没有 ping 通宿主机

如果遇到 ping 不通或者其它的问题，可以参考本节最后《tftp 烧写常见错误分析》小节。
