IPL block is bad on DiskOnChip 2000

Dear all,

I have successfully DFORMATted my MD2202-D64 today, and try to install a
jffs2 file system to it.
I created a root.jffs2 using mkfs.jffs2 and tried both "cp root.jffs2
/dev/mtd0" and "dd if=root.jffs2 of=/dev/mtdblock0", but I still can't
"mount -t jffs2 /dev/mtdblock0 /mnt". (Yes, I know I missed the "erase"
command after I check the HowTo again.)

When I want to start again with dformat, I get "/ERROR - IPL block is bad."

I searched from google and I found Tim has the same problem but seems
has no solution.

Does anyone know a solution to this?
