Nand Flash Driver for K9k2G16U0M Chip in WInCE 4.2 .NET

Hi All,

I am writting device driver for Nand Flash Chip
(K9k2G16U0M Chip).I am using Microsoft Platform builder 4.2 .NET.
In the Nand Flash K9K2G16U0M Chip,Page size is 1024 words and 32
words as spare area.
I want to know the details of this spare area,I mean where the ECC
code,Bad Block Information and other information is to be written.
Where can i get it's specification ?

Anyother suggestion is mostwelcome.

Regards,
Ajay

You can refer to the FMD driver provided in PB for how to write a
NandFlash driver. However, the biggest problem here is that CE.NET 4.2
currently doesn't support a file system that has a sector size different
than 512. A couple of places need to changed in the WinCE fat file system
itself to make this work. There were some discussions in the newsgroup, do a
google and you may find some useful information.

Making changes to FAT won't solve the problem since the FAT code is part of
the SHARED SOURCE and you are not allowed to ship modified versions
of the shared code.
