完全搞定，我以前发图说还有问题，问题就是不能web升级，并且手动灌固件也无法正常启动到dd，总是重启，现在终于搞定了。太晚了，有时间再写吧，还是上图。
请大家注意：看了老外的文章好像ag108 在rc6.2后才能通过web升级没有动手能力的朋友在rc6.2以下的版本不要通过web升级（我没有时间证实它）。我是手刷rc6.2后才通过web升到v24sp1、v24sp2-14896的。

这是v24sp1 web 升级过程中 串口反馈信息 这个升级信息与以前的反馈信息大不一样

今天有空就总结一下过程吧！
重点：
干没有把握的事情前都要备份，这是很总要的。

本人自从收到这个板子后从找jtag口-〉做jtag线-〉刷网上现成redboot-〉自编redboot-〉灌dd-〉用别人board infomation-〉改board infomation-〉成功
经历了大量的失败。

这次我说说网上基本没有提到过的atheros的board infomation（简称 bdinfo）

经lintel提示是没有cpu信息，经过联系才知道只要是atheros的主板在flash后部都有一个保留区，存储的是bdinfo，
bdinfo 一般大小为64k 或128k，bdinfo主要包含你的主板信息，cpu类型、mac地址、radio info等。很重要！
这是dwl-2100ap 的bdinfo片段


这是7800h原始的bdinfo

这是dir-300 bdinfo


发现7800h的bdinfo 与别的不一样，（dwl-2100ap 用的是vxwork）
-----------------------------------------------------------------
有意思的是我查到dd的论坛上有一个帖子 “how to recover board config for dir-300”
http://www.dd-wrt.com/phpBB2/viewtopic.php?t=39290&postdays=0&postorder=asc&start=0&sid=3c481cf3ad60b07d894788979aa956d8

提到一个网页能生成board info
http://www.shadowandy.net/2009/02/generating-dir-300s-board-config.htm
http://www.shadowandy.net/wp/wp-content/uploads/dir300generator.php
有dir-300的朋友可以看看

这些信息也让我走了很多弯路觉得可能以后的版本没有支持我的flash
差点准备重新编译dd了但是我想到编译redboot的经历，我就后怕（代码复杂，有很多看不懂。现在很佩服那些老外dd这个东西是怎么编出来的）
也就准备这么样了不就是用老版本的dd吗总比砖块好些吗。
山穷水尽疑无路？
无意中发现了些东西 （atheros 主要芯片演进史）
http://oldwiki.openwrt.org/AtherosPort.html?highlight=%28CategoryOpenWrtPort%29
http://www.linux-mips.org/wiki/Atheros_SOC#Atheros_WiSoC_generations.2Fevolution

我的主板信息应该为
AR5002AP-2X (AR5312 CPU + AR5112 2.4/5GHz RoC + AR2112 2.4GHz RoC)
AR5002AP-2X 这个与dwl-2100的信息不太一样，修改我的bdinfo，然后写进主板，结果就是目前的结果了，可以用高版本的dd。
现在修改的结果

我也简单讲讲这里面的内容（都是试出来的）
开头必须为5311 这是bdinfo的标志代码，不然在redboot中bdmove 和bdrestore两个命令无法识别bdinfo
那个$在dir-300中是}我不知道是什么，Atheros AR5002-2X就是cpu信息了 default 一个字不能少，
在偏移量0x23-0x5f我不知道有什么作用但是不能少，0x60后就是mac 地址了在这个主板上
0x60后前6个字节是wlan0的mac，7-12是lan的mac，13-18是wan的mac，23-28是wlan1的mac

关于保存与刷写bdinfo的方法：
1、保存
   在dd中我暂时没有找到办法保存，可以用jtag，但是我想到了在redboot中一个笨办法用 d -b 0xbe3e0000 -l 0x20000 命令redboot会显示bdinfo的信息，找一个有历史记录的telnet 软件，将显示的16进制代码写进一个文件就可以保存了（我没有用过这个办法）
2、刷写
   2.1 用jtag
   2.2在redboot中可以对任意地址位操作但是redboot在正常编译中是有保留地址的，这个保留地址也没有办法写，但是可以编译一个没有保留地址的redboot，然后在redboot中写bdinfo。
       我的操作方法是编译一个没有保留地址的redboot 的ram版本然后在redboot ram版本中写bdinfo，写完后重启就好了，我嫌jtag太慢了。
       注：这个方法对有一定能力的朋友适用

jiuweiljp

在128k的bdinfo中后64k可能是radio info
这是7800h的原始信息

这是dwl-2100的信息



我不知道里面的含义，有知道请提供。

经过长时间的弄这个东西（中间有段时间放弃了，不就100多元钱吗（还不是我花的））
在没有这个主板的jtag接口信息，没有现成redboot，没有正确的board info的情况下最终弄成我朋友想要的dd，实在是太费事了，有点累了。
我现在真的很想知道taobao上把7800h刷成dd的是怎么弄的，难道是将一个ag108的flash拷贝出来，然后写进7800h中？

太强了，要支持！！！！！

这个东西的中继，我一直都没搞明白怎么用，跟Broadcom的中继感觉有太多不一样。你先试着用一段时间吧。
220的CPU，应该比你手上的850G速度要快！
