编译器arm-linux-gcc3.4.1 redhat9 s3c2410的平台

root.cramfs使用的是2.4.18的

也试过把ecc去掉（/drivers/mtd/nand/s3c2410.c）

但打印的错误还是一样的

klrfpaul

noinitrd root=/dev/mtdblock3 init=/linuxrc console=ttySAC0 mac=00:01:5D:68:7A:0F
把linux cmd line改成这样了也还是一样的错误

我看网上说2.6.14不支持devfs，是不是这个原因?

另外我用的root.cramfs是开发板（2.4.18内核）自带的，这样可以吗？

问题已经解决
是make menuconfig的时候要选上cramfs支持
