请问华美A100怎么刷固件

如果其他步骤都无误。检查是否网线没插好。或者换条网线

我想了解下具体的连线方式。操作流程是按视频上来的, 但是视频中只是说用tftp下载，能否用画板详细画出连线方式。还有tftp的设置，为什么我这边下载就是不行呢，出现TTTT字样，视频中就可以用

关 360试试

电脑没有安装360，金山毒霸也退出了，一样不行。同样的我用tftp刷mini2440的内核、文件系统等都没有问题，下面是在华美A100上刷固件时候串口的提示信息

换根网线呢

不是这些小错误，同样我用这些网线和环境给mini2440  用tftp的方式烧写都没有问题。

麻烦能把视频中可以烧写程序的机器的boot环境变量亮出来看一下吗。

你先看能否print

请问你解决了吗？我遇到了和你一样的问题！

没解决，还是很难下载，偶尔成功

1. 你先测试是不是网络环境问题
