rg100a-aa adsl+ 无线猫 坛友应该都了解,一代神器,可以adsl上网,也可以改无线路由器,刷openwrt,bt挂机,可玩性很高
俺就是通过rg100a-aa入门openwrt的,性价比特别高,10元, 原厂配置 CPU:300MHz 16Mflash 32M 内存 单USB口,54M无线
虽然现在看过来,它无线速率太低,不过若WAN口光纤宽带不超过20M,还是可以跑得动的
故障:
刷openwrt后,系统有时能启动,有时不行,但进cfe正常,也能正常刷机
不成功时,cfe启动完成后,加载openwrt内核过程中,ttl线上报错:
---------------------------------------------------------------------
SQUASHFS error: Unable to read fragment cache entry
jffs2_scan_xattr_node: node CRC failed
----------------------------------------------------------------------
ttl线接法如下,(红圈小电容为100uf,10V):
该机服役多年,估计就是电容失效的原因,拆机图如下(红圈小电容为100uf,10V):
换电容后测试了解到,更换红圈中的电容c176(1000uf,10V)就不报错了
测试2-3天后,一切正常,后来又发现用迅雷无线下载电影时,无线会当掉
将c172 100uf 10v电容换成1000uf 10v(红圈),搞定
另外,系统程序飞掉时,ttl出现如下信息,并且不断刷屏,也是换C172这颗电容
ttl信息:

最后刷了新版的Chaos Calmer 15.05.1,文件名openwrt-15.05.1-brcm63xx-generic-RG100A-squashfs-cfe.bin
烤机中,如图
无线也正常,如图
跑了3天多了,一直很稳定
连续15天不关机,至此维修及拷机完毕
