busybox
but i try to use 2.6.22.12(without devfs) instead ,it comes those words

how can I mount the rootfs?
I configed sysfs and all the options under "pseudo file system"
configed "do own ecc" and make driver/mtd/nand/s3c2410.c:
ecc.mode=nand_ecc_none
also mknod console zero null
but what's the problem?
