NetCore NW714 v2.0路由器TTL救砖

路由器成砖状态：

1.客户端无法获取IP地址

2.客户端设置IP地址后，无法PING通路由器IP地址。

3.路由器按reset按钮，无法重置路由器。

4.路由器的指示灯只有SYS和WPS亮，WPS微亮。

5.在路由器的LAN口和WLAN口插入网线，相应的只是灯亮。

解决思路：

通过上述的路由器状态判断，只有通过TTL线刷方式才能救活路由器。

路由器外观：

路由器内部（接口和串口连接已做好）：

可以看到上图右上角，被厂家预留出了4个接线孔，VCC、RXD、TXD、GND，正好方便我用TTL刷机，这里我只需用到RXD、TXD、GND这三个线就可以。将这三个线焊接出热线针脚，然后用TTL下载器进行连接，连接示意图如下：

正式刷机：

1.将TTL下载器的线与路由器的三个阵脚进行正确连接。

2.将TTL下载器连接电脑。

3.打开设备管理器查看TTL下载器所对应的COM口。

4.打开SecureCRT，按照下图设置：

5.进入SecureCRT，查看串口信息。

6.给路由器上电，串口信息如下。

7.看到UBoot，我瞬间就笑了。这里我选择2，进入Load system code then write to Flash via TFTP. （Uboot刷机有很多方法，这里为了方便起见，我选择2）。

2: System Load Linux Kernel then write to Flash via TFTP. Warning!! Erase Linux in Flash then burn new one. Are you sure?(Y/N)

输入Y

接下来，会让你设置路由器IP、TFTP服务IP和刷机固件的名字。在此之前需要在电脑上把TFTP设置好。

然后，只需要等待就可以了。

从反馈信息可以看出“led light error”错误，不过没关系，因为NW714的路由器的固件在网上找不到，我这里刷了一个和它配置相同的NW710的固件。

刷机完成后，赶紧登录路由器的登录地址试一试，果不其然，成功！

此过程涉及工具：

TFTT软件，TTL下载器，网线，电脑，固件，SecureCRT
