开始都可以认出来，刷了就认不到了，换了几个版本的JTAG软件，还是认不到，求救
jtag debugger, jtag openocd, jtag读写flash

确定内存什么的都没动(升级)过？如果焊过，就先处理焊过的，原本没动的最好不要动，我以前一台内存升级了，但后来调试时成砖了，用jtag也识别不了，疑心到别的芯片，最终还是复焊了内存才解决

我前几天发生的情形和楼主差不多，参见我的帖子

也是在刷新CFE后，识别不到FLASH，用上了各种办法，包括补焊芯片，还是不行，最后偶然翻到篇帖子，用了如下参数

Jtag.exe -erase:cfe /skipdetect /instrlen:8 /fc:98

说实话，我也不知道参数什么意思， 后面的/fc:98 是指定的我的FLASH芯片型号！

结果有动静了！

识别出FLASH后就可以按照正常参数操作了，不过现在我的是刷新后重启仍旧TEL=100.

还有，楼主还可以先打开CMD窗口，输入好命令 然后路由加电，加电的同时敲回车刷新

不成功可以重复施用！

希望能帮到你！

这步就出现错误了，处理器没有进入调试模式，所以后面的操作根本就没有真正执行

遇到这种情况在试几次，还不行的话，那你就断电重启吧
