Yes, I was pointed there yesterday, i.e. to the "map" drivers.
Wrote one and commited and now I am mounting my flash partitions all
over the place...... 8-)

Thanks,

jffs in flash?

[Kári Davíðsson]

Hi,

I have one flash chip (4MB) that i want to use parts of as a disk, e.g.
with jffs or jffs2.
It seems to me that the jffs wants to use the whole chip under the fs.
Is this correct?
If not how can I tell jffs to start using the flash at some offset?

Thanks,

K.D.

Re: jffs in flash?

[Xavier DEBREUIL]

correct me if I am wrong : in sa1100-flash.c, there are several examples where
a flash is divided into several partitions ;

for example : I have a 16Mbit flash and I have divided it into two partitions of
8Mbit each

static struct mtd_partition is_blue00_partitions[] = {
   { name : "boot partition",
    offset : 0,
    size : 0x00200000 },
   { name : "cramfs partition",
    offset : 0x00200000,
    size : 0x00200000 }
};
