Wrong CLEANMARKER Position

Wrong CLEANMARKER Position

[Chen Zhigao]

Hi,

I try to boot my IXP425 board with a JFFS2 root FS on the MTD, into 
which I burned two images, "zImage" and "jffs2". I got a lot of messages 
regarding wrong CLEANMARKER position during booting, although I can use 
the root FS. What's wrong here?

VFS: Mounted root (jffs2 filesystem).
====================================================

Another problem is that I can not find any "/dev/mtd*" in the FS, though 
"cat /proc/mtd" can return me the flash partition infor.

Any comment is welcome.

Cleanmarkers were put every 0x00010000 bytes (64k), block size for
jffs2 is 128k.  What is the real block size for the flashes?

I think IXP425 flash block size is 128k, because RedBoot asked me to 
start a flash address on multiple of 0x20000 when I burned the images. 
How can I fix the errors?

Thanks,
