Next message: smartmedia block driver

Hi all,
I've successfully completed the "read" part of a smartmedia driver for the
Samsung board smdk2410.
The Linux kernel is 2.4.18 (mandatory for this board)
The driver is composed by 3 modules:
s3c2410nand.o
smdk2410.o
mtdblock.o

I've modified these sources in order to read the smartmedia and build up the
logical to physical block address map.
Now I am able to mount a vfat filesystem on the smartmedia:
mount -t vfat /dev/mtdblock0 /mnt/smartmedia

My problem is that I have no idea about how to write sectors to smartmedia.
I have already the low level function nand_write_ecc, but I need help from
the logical side.
When the mtdblock needs a logical sector (req->sector), I just use my table
to translate the logical block address to physical block address (the low
level driver module s3c2410nand.o reads only physical sectors) and pass this
physical address to the nand_read_ecc function.
I suppose that when I write, a new logical or physical address must be
written in the OOB area of the requested block, but which is the logic?

is anybody able to help me?

regards

Luca

I've been unable to contact Luca to see what sort of state the SD driver
for SMDK2410is now in, almost a year later ... does anyone have any details?

I have an SMDK2410 which I'd like to press into development work, but the
only large'ishmedia I have for it is a 512Meg SD Card, which I'd like to put all the dev
tools on ... is thispossible?  Maybe someone has a working SD driver for SMDK2410?  (linux
kernel 2.4.18)

Join the IRC channel #mtd on irc.freenode.net; it's being discussed
there.

I've had smartmedia/nand working on our EB2410ITX under 2.4.26
