Hello,

Does a single filesystem JFFS2 need that all sectors of flash partition
are same size or
could we use different sector size (as for some flash that mix small and
big sector). ?

Thanks

Sylvain

JFFS2 only operates with a single sector size. However, when you have 
smaller erase blocks you will generally find that they add up to a single 
block's worth of the normal erase size. For example, 8*8KiB + 15*64KiB. 

JFFS2 will work OK on that, and just treat the 8*8KiB blocks as a single 
64KiB block.
