Hi,

Urm, no I wanted compression ... but a 2.4G celeron should be able to do
> 29k/sec !

Using priority ..

Q: I have an erasesize of 128k (and consequently a sector size of 128k)
because the memory in question is 256Mb.
(JFFS2 modifies sizes to fit within a malloc [fs.c])

Could this be the problem ?
