讨论EC1308修改
我用telnet登录到EC1308里。在-rwxrwxrwx 1 root root 8657 Nov72011 himr-rwxrwxrwx 1 root root 89029 Nov72011 iwconfig
-rwxrwxrwx 1 root root 83813 Nov72011 iwpriv发现这个himr的格式是：
usage: himr <address> <value>. sample: himr 0x80040000 0x0
不知道所谓的写MAC，SN是否就是在特定的地址写特定的数值？
补充内容 (2012-3-8 09:42):

这是修改源代码，可惜我不会编译。 那些远程改MAC和SN的是否就是利用这个himr程序，将MAC和SN写到特定的地址？ 急切想知道远程是如何改的 估计就是执行这个命令。
himr <address> <value>. sample: himr 0x80040000 0x0
例如知道MAC 00-11-22-33-44-55 在地址 0x80040000 位置。
himr 0x80040000 0x00
himr 0x80040001 0x11
himr 0x80040002 0x22
himr 0x80040003 0x33
himr 0x80040004 0x44
himr 0x80040005 0x55
SN也是类似。
现在主要是，谁告诉我们MAC和SN的地址？
一直想找到运程修改MAC和SN的办法，苦于无解啊 wowocom 发表于 2012-3-10 11:37 static/image/common/back.gif

修改的代码早有了。到今天不会编译。

} 在ubuntu 下，释放cross-compiler-armv5l.tar.bz2文件，编译fix1308.c通过。可以修改EC1308了。 0522 发表于 2012-3-23 18:24 static/image/common/back.gif

你用的编译命令行格式是什么？
已经编译出修改文件，并且修改成功
