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。

ksh

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 :

Probably your kernel can not find your filesystem.So you should tell kernel where is filesystem.

我试了其他的版本，但也出现以下错误，下面的错误又是怎么产生的？
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。

有人没？？？？？谁能告诉我一下啊！！！郁闷！

suifengzjp

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？

yaka_96

把type=R属性改为type=RW就没有上面的问题了

suifengzjp

谢谢哈
