Re: IS WinCE5.0 Support MLC NAND FLASH

Sorry sir, Thank you your reply.
you misunderstand me.
i had realized the SLC NAND Flash driver already,
it now can support SLC such as: Samsung k9F.

but my boss ask me if it can support MLC in CE5.0 and CE6.0,
we want to change our SLC NAND Flash to MLC NAND Flash.

I believe there is enough freedom on the FMD PDD layer to
handle all of these and hide the actual device specifics
from the MDD. Even though for some reason it is not
easy/possible to fit MLC into native CE FMD driver
architecture, you can always build your own flash driver.
It is just a block device after all.

Alternatively back port FMD library from 6.0 to 5.0, it is
likely supporting MLC.

Anyway, be prepared for some coding. I have a feeling you
are expecting to drag some magic item from the catalog to
the OS design and that is it. Nope, in the most cases you
will need to code at least the FMD PDD part. The only
exceptions are a couple of chips that have the corresponding
drivers included in PB...

But i see in wince5.0 help doucment. it says that:
" Flash driver does not support devices that require sequential page
programming operations
The Windows CE Flash driver does not support devices that require sequential
page programming operations, which include certain large-sector devices and
NAND MLC. "

what this means?
