Re: How to auto mount a PART_DOS32 patition in WinCE4.2 with 2k byte/page nandflash?

CE4.2 does not support sectors that are not 512. So you can either modify
your driver to manage your 2048 sectors as 4 sectors of 512 or customize the
FATUTIL code (I think the problem comes from a hard coded value inside)
after having cloned it.

Hello all:
My device is about S3C2440, it has a large page(2k byte/page)
nandflash(SAMSUNG K9F4G08,

512M), My OS is WinCE4.2 and the BSP is SMDK2440, so My bootlaoders are
nboot and eboot.

Using the BootPart library in eboot, the nandflash in my device has
two partions:BINFS

and FAT32. After the OS is running, I go to the storage manager in
control pannels and can

see two parts(part00, part01) in the list box, the Properties of each
Partition are OK, as

follows:

part00 size 18432 sectors
type 0x21
file system binfs.dll
flag 0x00000000

part01 size 242496 sectors
type 0x0B
file system fatfsd.dll
flag 0x00000000

However, the PART_DOS32 partition(part01) is not mounted by
WinCE4.2, and can not see

the folder "ResidentFlash". If select the Property of part01, the
Partition Properties

dialog correctly displays fatfsd.dll as the file system, but clicking
the mount button just

opens a message box that sais "Unable to mount partition". Even firstly
click the format

button, it shows ok, secondly click the mount button again, it also
shows "Unable

to mount partition".

The registry in the platform.reg used are as follows:
