Hi all,

i read several mail about this limitation.

I have a 4 KiB erase-size, common of some SST nor flash'es like mine 
(SST 39VF3201B).

 From all the posts i read here in the list, there seems not to be any 
solution guaranteed.

The tricky change to mkfs.jffs2 don't work for me. It seems to work for 
small files, but i still get error messages copying a 600KB file in the 
partition.
If it's true that the minimal jffs2 block is 4KB + some bytes, of course 
the patch to mkfs.jffs2 can't work.

Some one suggested the "virtual erase block" solution. I would like to 
try to implement it, if i have the time.

In any case, for the common users, is there maybe another flash file 
system that can work with 4KiB erase size ?

Many thanks,
Regards
