can't boot with DiskOnChip2000 / nftlmount UnitSizeFactor ????

[Frederic Marmond]

well, sorry, in my last mail I titled about UnitSizeFactor != 1, but 
didn't speak about it.

So, i'm wondering about this check (in drivers/mtd/nftlmount.c in kernel 
2.4.x)
is there any info to make my nftlmount works, even if i have this 
message? ("Sorry, we don't support UnitSizeFactor of != 1 yet.")

here is my dmesg about DOC2000:
Possible DiskOnChip with unknown ChipID FF found at 0xc8000

Sorry, we don't support UnitSizeFactor of != 1 yet.
Could not find valid boot record
Could not mount NFTL device

I would really appreciate any help of any type, as i spent too much time 
on this, and my boss is very strong at aïkido, kick-boxing and all this 
stuff... ;-)

thanks in advance!

I circumvented such problem by re-formatting the chip with the MTD
nftlformat utility.  The latter has a built-in check for erase block size
which you may need to remove if you find the risk acceptable.

...
i made a "nftl_format /dev/mtd0 2097152", from the lastest CVS from 
mtd-tool...
it works fine, and i can make a fs (ext2) on /dev/nftla1 (after, of 
course having made a fdisk /dev/nftla)

but the message still remain at boot time (see it in dmesg
NFTL driver: nftlcore.c $Revision: 1.82 $, nftlmount.c $Revision: 1.25 $
Sorry, we don't support UnitSizeFactor of != 1 yet.
Could not find valid boot record
Could not mount NFTL device
)

this check is in nftlmount.c in kernel directory (drivers/mtd/nftlmount.c)
do you mean that i can comment this check?
do you know what is the risk?
