linux cramfs文件系统问题 [复制链接]

linux-2.6.20的内核，cramfs文件系统，再启动到最后挂载文件系统时偶尔会出现错误：
Error -5 while decompressing!
c0327d8a(1928)->c3dfc000(4096)
Error -3 while decompressing!

注：1，ECC校验已经改成NAND_ECC_NONE
    2，坏块已经处理
    3，LCD缓冲分配内存较小时出现几率也较小，如320*240显示的时候基本不出问题

前面的信息呢，也贴上来吧...

这时正常启动时的信息，出错一般是在启动QTE时

貌似进入 busybox 后出错的嘛，是不是 busybox 移植的有问题呢 ...

ty0001

应该不是busybox的问题，控制台可以用的。
启动QT图形界面时，cramfs解压产生数据错误
网上有人这么说：
Cramfs can not be extracted
since memory couldn't be allocated for the output buffer. Most probably
you got an application that leaks memory. To solve this you have to
observe the memory usage of the system.

现在还是不知道怎么下手

/root 文件系统放在内存里面嘛，cramfs 的数据解压到 /root 文件系统下，
不行么...

easybyte

我的文件系统是放在nandflash里的，启动过程中读取并解压

fangning

应该是文件系统错误，
检查
/etc/init.d/rcS
和
/usr/lib/ipkg/externinfo
看看有什么问题没

可以确定文件系统是没有问题的

哪位高手来给点建议

更换一片nand flash试一下，我遇到过这个问题
