4月份淘了一台8230，已经改好64M内存，4318的无线，4MFlash，刷的Linksys WRTSL54GS的CFE，固件为tomato1.19限速版，放公司里面使用3月有余带机10几台不曾关机，效果非常好。很稳定。
最近家里搜到几个未加密的无线信号，想跟自己的ADSL合在一起加速，所以带回来准备刷TT DualWan。没想到拿回家第二天一开机发现变砖头，心里那个郁闷啊。
症状是：开路由，无法分配IP给电脑；
给电脑固定一个IP，ping不通路由器；
网线插哪个LAN口，哪个LAN灯就亮；
无线连接不上。
直接jtag，由于不熟悉，线也做的不好，尤其是头子。导致flash识别不好，好不容易连上了，一时手快erase了wholeflash。幸好以前备份了CFE。flash好CFE后，tftp上传了TT DualWan 的固件。中间出了个小插曲，因为没经验，看到tftp的进度条完了后便迫不及待的拔掉了电源，结果是固件还没来得及从内存中烧到flash里面，重启还是砖头一块。我在这个地方卡了2天啊，jtag线都快被我拉断了。
终于登陆上了久违的TT界面，好好学习了一下TT DualWan，成功设置。下载可以达到440K，已经是极限了。爽
修好后的第二天早上启动路由器，TMD又不能启动啦。跟原来的症状一模一样。
立马jtag清空了wholeflash，从恩山下了一个Linksys WRTSL54GS的CFE，跟我备份的一比较，一模一样的，MD5都一样。烧进去下载回来的CFE，tftp以前的TT1.19的老版本，又可以登录进去了。接到猫上测试了一天很好，屁事都没有。
修好后的第三天早上启动路由器，我CAo，我服了，又不能启动了。这次下狠心找jakey_ye买了TTL线。接上去以后开机TTL无任何信息，反复多次开关路由器，终于TTL被我的执着感动，显示了如下信息：

当我再次拔插的时候，机器又自己好了，TTL信息如下：

我就纳闷了怎么无缘无故会Boot program checksum is invalid呢？
后来经过我的测试发现，只要关闭路由器约10分钟左右，再次开启路由器一定会启动不了。有点像汽车冷车不好启动。
请教各位，你们有碰到过这样的现象吗？
我的想法是，是不是哪个电容有问题？因为机器放置一会电容的电会放完，开机了电容充电需要一定的时间。充电完成了才能启动。
又或者内存虚焊啦？我拿回来路上震动导致接触不良？
还请各位大大不吝赐教。 |
