Hi Gonzalo,

I switched from YAFFS to JFFS2 on my TS-7250 projects (2.4 kernel)
because I had problems with YAFFS.  The worst was that it would mark
blocks as bad for no reason and there seems to be no way to unmark
them.  After having a couple of my TS-7250 boards become useless
because of too many bad blocks, I gave up and switched to JFFS2.  Note
that the stock 2.4 kernel from Technologic didn't fully support JFFS2
at that time (not sure if it does now plus they've since moved to 2.6)
so I had to backport some JFFS2 stuff from another kernel branch I
picked up somewhere else.  In any case I've been using JFFS2 since
without incident or problems.  Hope this info helps.
