Re: [Yaffs] Yaffs on 2.6.11

Thanks.
I have compiled yaffs into kernel.
It can work with cramfs(root fs partition) and yaffs(usr partition).
But error found when use yaffs as root fs :
I use mkyaffsimage to get the rootyaffs.img.

linux command line is: "noinitrd root=/dev/mtdblock/3 init=/linuxrc
console=tty"MACH_TYPE = 193

So I want to erase the nand first.
Using NFS, then,
[root@localhost root_china]# file mkyaffs.arm
mkyaffs.arm: ELF 32-bit LSB executable, ARM, version 1 (ARM), for
GNU/Linux 2.4.0, dynamically linked (uses shared libs), not stripped
[root@localhost root_china]# file mkyaffsimage
mkyaffsimage: ELF 32-bit LSB executable, Intel 80386, version 1
(SYSV), for GNU/Linux 2.2.5, dynamically linked (uses shared libs),
not stripped

How can I successfully use yaffs as root fs.
