以上问题是怎么回事呀，我试了好几个版本都这样，S3C44B0也试过，请高手帮忙指点一下！！！！谢谢。 That means you try to write some data to 0x0 , but mem at 0x0 is read-only according to your skyeye.conf.So there is probably something wrong in your linux image or your skyeye.conf . Aha,you are right,thanks!but,when i modify the attribute of memory,some error occured :
# skyeye linux

针对找不文件系统的问题我该怎么做？我已经试了三个2.4版本，都出现这样那样的问题。

(SkyEye) 有人没？？？？？谁能告诉我一下啊！！！郁闷！ 楼主 ，我遇到和你一样的问题了，SKYEYE: WARNING: illegal write byte to 0xb7b5 of 0xa9 @ 0x0
这个错误你是如何解决的？ 把type=R属性改为type=RW就没有上面的问题了 谢谢哈
