myLG070 无线路由 故障 拆机图 JTAG

手上有一MYLG070的无线路由无线可以找到但有密码,恢复出厂设置也是如此,连上有线无反映,对应指示灯也不亮,怀疑是固件问题,可以帮我看下这个机上自带的是TTL还是JTAG 如何时连,还请高手指点.

那排针是JTAG,不过这个Retel芯片不知道支部支持哦。

这个排针是机器本来就有的,Retel 也是自带的网卡,CPU是什么看不到,上面散热器拿不下来,粘的好结实,不知这个JTAG 是用什么接法?
有用过的朋友吗,指点下!

这个芯片很少见。。。继续等待吧

试验得出那个接口并不是JTAG 而是 TTL ,现在已用TTL得到启动信息,但是为什么进不了CFE 模式。

为什么进不了CFE 是不是CFE 已经坏了, 有高手能看懂的吗?

ralink的芯片,又有pci槽,牛机啊,不过芯片比较老,貌似那时候ralink没开源,不然就能刷op和dd了
