RG100-AA通过TTL线刷OpenWRT系统

发布时间:August 23, 2012 // 分类:OpenWrt // No Comments

不小心RG100-AA成砖了,先尝试用TTL修复吧,不行再使用JTAG,USB-TTL PL-2303_HX_数据线驱动

黑=GND
白=RXD
灰=TXD

RG100-AA TTL连接图,从左到右依次为:VCC-GND-RXD-TXD

以下开始刷机,按住路由reset键,然后开启路由电源,10秒左右松开reset键,进入CFE界面,输入e a回车清除flash信息,CFE登录账号和密码:

清除信息后会重新启动进入CFE界面,将网络插入LAN4接口,通过浏览器打开192.168.1.1进入WEB升级界面,密码同上,上传OpenWRT固件刷机即可。
整个步骤securecrt显示如下:

2015.02.09更新:
Windows8.1已自带TTL数据线驱动,插入后通过设备管理器查看COM接口:

然后点击查看属性,后面使用xshell或securecrt要用到:
2015-02-09_075357.png
使用xshell新建会话,速率和上面的不一样:

然后连接:

Connected.

后面直接开机和进入CFE会显示启动界面,可用于进入CFE刷机或SSH不能连接Openwrt路由时使用。
