Re: Newbie: JFFS2 & serial flash

Hi Everyone,
This is probably a very silly question but here goes...
I noticed the ECOS has support for JFFS2 and serial flash devices, can
JFFS2 use serial flash?
Yes it can, but there are some issues with DataFlash's sector size wich
is not a power of 2.
There are a few places in JFFS2 where the sector size is presumed to be
power of 2 - mostly
code like this '... & ~(sector_size-1)'. Also there are some issues with
mkfs.jffs2.
