  The command I used is as followed:
mkfs.jffs2 -p --eraseblock=16KiB -l -d ./jffsRoot -o jffs2.image
I changed the mkfs.jffs2 so that it allows me to create image with 16KiB 
erased size. I presumed it is not a problem to make the changed, but may 
be I was wrong. The raised the question about my changes sometimes ago 
Please let me know, if my assumption is wrong.

That sounds a lot more promising. Probably there is somthing wrong my 
configuration, I will look into my configuration again.
