I am usig the same board and face almost the same problem.
i have made the jffs2 file system but have used the defaut page size,ust reset the eraseblock size to 16k,i am a newbie and don not kno where is the messing done,because when i boot the kernel(with all the support for the jffs2 FS,it doesnot bootup,even I am not able to load the kernel o the ram, i dun kno if i have messed up the kernel compilation too)
the command used for jffs2 making is:
mkfs.jffs2 -o /root/rootfs.jffs2 -e 0x4000 -n -d/test/
/test is arbitary directory made
is that wrong.
in the /test i have copied the direcory structure.
can u please temme the configuration of the kernel for the same...
i will be waiting...
thanks i advance
