刷完还是PING不通192.168.1.1.

有大侠知道原因吗？

用了两个命令：输入 brjtag -probeonly /erasechip 全片擦除flash芯片数据
                   brjtag -flash:cfe                      写入CFE

是不是那里做的不对有总是？
请大家帮帮忙。

可能是CFE.BIN文件不对。方法没错。
另外你可以试着换不同的LAN口试试（电脑网卡必须手动指定IP）

LZ要注意的是，你的Brjtag软件版本有点低了，有些问题。。。
S29GL128的Flash的起始地址是1e000000，而你现在显示的是1f000000
所以就算你的CFE正常写入，但设备读取的启动地址还是1e000000，由于你这个地方并没有写入新的CFE。所以问题还是原来的，没有改变。

解决，下载最新的Brjtag软件来使用，比如1.8C或者1.9A

5楼的能说下jtag怎么使用吗 我也准备刷2650 但是不知道怎么操作 已经刷成砖了 JTAG线已经连接好了

zzq0106

线连好之后先不要开猫的电源
1,giveio.sys复制到windows\system32\drivers\下
2,运行loaddrv.exe把路径改成c:\windows\system32\drivers\giveio.sys，依次点install，start，ok
3,把cfe.bin复制到brjtag同一路径下，开始，运行，cmd，输入x:\brjtag -flash:cfe (x是brjtag所在的盘符)
，不要回车，此时打开猫的电源，看猫的一排指示灯一齐闪过之时按回车，如果成功的话会看到类似于

这样的画面
然后关猫的电源，拔下jtag，接上ttl线和网线，打开超级终端，打开猫电源，会提示如下画面:

设好pc的ip为192.168.1.100,进入192.168.1.1，载入固件(建议用改版固件2009.4(基于Dlink DSL-2650U RU1.00带cfe)，刷完之后如果不能正常运行的话在cfe下输入f命令再刷一次，这次如果成功就再用cfe>e n清空nvram并重新配置参数即可

谢谢楼上的几位.后来在网上找到了个256K的CFE.刷过后.机器可以用了.
先这样用几天.有时间在试试新软件.
