Subject: DataFlash & writesize
Date: Tue, 20 Jun 2006 11:49:51 +0400	[thread overview]
Message-ID: <4497A89F.4010202@yandex.ru> (raw)

Hello Andrew,

AFAIR you are the guy who provided DataFlash drivers. May I ask you to 
fix them as I suspect they may be broken in mtd-2.6.git.

We've introduced a mtd->writesize field recently and it has to be filled 
by the flash driver. The field contains the minimal Flash's I/O unit 
size. For NOR it is 1, for NAND it is NAND page, or less if multiple 
writes to a NAND page are supported, etc. I once read a DataFlash 
datasheet and suspect this has to be DataFlash sector size, but I'm not 
sure.

So, I'm asking you to initialize mtd->writesize correctly.

Thanks.
