Hi,
I would not be surprised to see JFFS2 problems with most i.MX platforms. The nand ecc includes the spare area so you can not write a JFFS2 free marker to spare and then later write to the main area. There are patches for JFFS2 in the kernel for this. I don't know about u-boot.
Also as a general remark, JFFS2 on larger devices _is_ really slow. Because of this _and_ the handling on blocks going bad on reads, we therefore suggest to our customers to use UBI + UBIFS on NAND.
Best wishes Detlev
