Reduce the booting time of NAND Driver

Hi all,

I am using WinCE 5.0. There is a NAND Flash on the device.
During the device bootup phase, WinCE is checking the status of all
the NAND Blocks, which is increasing the booting time of the device.
Is there any way I can bypass this so that i can reduce the booting
time!!
The flag FATFS_DISABLE_AUTOSCAN of fat fsd has been set but it
keeps checking the status of all the blocks while booting. Please help
me.

Thanks,
Sarath

Not an expert on this, but I think this comes from the FAL (and not the FAT
FSD). You can write your own, but this is not an easy task.

Hi Anthony,
Thanks a lot for the suggestion. Will I need to rewrite
entire FAL or modifications to that will be sufficient??
Can you tell me why is this reading done when the system is
booting??

Thanks,
Sarath Chandra. B

I think so, yes.
From what I remember on the FAL : for wear levelling management, the FAL
builds a table where you have the match between logical sector (for the FSD)
and physical sector (on the flash), and this table is stored in the flash
spare parts.

Hi Anthony,
I have a doubt there. If the table is stored in the spare parts
then the table will be persistant even for reboots. So, why is this
done every time the device boots??

Is there any document where I can read about the wear levelling
management in Window CE??

Thanks a lot,
Sarath Chandra. B

because it needs to read all the sectors to be able to re-build this table.
