linux cramfs文件系统问题

jyhsaka159 2009-5-9 16:26 楼主

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

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 ...

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
