论坛搜一搜，有教程的，印象中是去掉c278，TTL设置是115200/8/N/1

去掉C278乱码，之后又重新连接，还是不能停止。。

那你可能得考虑考虑换跟线试试...

谢谢哥们，确实是中间的那根线问题，换了下按tpl可以停止了，已经修复好了。

ar7240> 进去以后。 可以设置路由的IP地址，和服务器的IP地址，此服务器IP地址指的是当前电脑地址，如192.168.1.10 ,路由地址如192.168.1.2, 可以用以下命令：
ar7240>setenv ipaddr 192.168.1.2
ar7240>setenv serverip 192.168.1.10

设完地址以后，可以查一下是否正确，命令是：
ar7240>printenv

然后在电脑上建立一个tftp服务器，把固件放在tftp服务器下。在uboot命令下，就可以把tftp上的固件刷到路由器上，这样就相当把固件刷到路由上。命令如下

ar7240> tftpboot 0x80000000 wr841n-v5.bin  (假设固件文件名为wr841n-v5.bin )

然后。执行如下命令。

ar7240> erase 0x9f020000 +0x3c0000
ar7240> cp.b 0x80000000 0x9f020000 0x3c0000
ar7240> bootm 0x9f020000

到这里路由会自动重启。刷机完毕。
