Nothing just leaps out at me, but you might verify whether you're running
the ROM Only or ROM & RAM filesystem, etc.

Ok, I have theFlashloading and showing up as adriveon my system. I
have set all the registry settings that I could find in the help
documentation to tell it to mount as the root file system.

How do I tell if it is working? If I create a folder under any of the
standard places (like My Docments) the folder disappears the next time
I boot up the system. Could this be because I am loading, running and
debugging from ram instead of flashing the unit and then trying it? Is
this the right way to verify it?

I looked into the registry and I have the following entries actually
in the file system:

[HKEY_LOCAL_MACHINE\Drivers\BuiltIn\NandFlash]
"Dll"="nandfcd.dll"
"Order"=dword:0
"Prefix"="DSK"
"Profile"="FlashDisk"
"IClass"=multi_sz:"{A4E7EDDA-E575-4252-9D6B-4195D48BB865}"
"FriendlyName"="i.MX21 NANDFLASHDriver"

; LoadFlags 0x01 == load synchronously
"LoadFlags"=dword:1
"BootPhase"=dword:0
; Note: if BinFS is used together with PS, then should ensure
; this is loaded after BinFS by setting order to 1 and that
; BinFS autoload order is 0.
"Order"=dword:0

[HKEY_LOCAL_MACHINE\System\StorageManager\Profiles\FlashDisk\FATFS]
; System registry in FATFS partition
"MountAsBootable"=dword:1
; To mount FAT partition as root
"MountAsRoot"=dword:1

Notice the MoustAsRoot setting and all.

I looked through the debug log and didn't see any errors. The only
thing I saw that stood out was:

It seems to be formatting thedrivewhen it boots. The only thing that
doesn't make sense if that is true is that if I create a folder
directly on thedrivethat is created (NANDFlash) it remains. So if I
create a folder on thatdriveit stays, but if I create a folder in
one of the standard folders they go away when I reboot.

Hi there,

Thanks for the quick reply. But my question is how should I confirm
that my root is mounted to flash? Becasue we are loosing data after
rebooting the device. Can I have list of catalog items that you have
added apart from those are added in Mobile handheld profile? Also you
have mentioned in the mailing thread that you added '
"MSPART.dll" explicitely.
Also I observed that when OS boots I get to see debug messages from
"FMD_Read" function and never get any calls to FMD_Write. What does
this mean? Are we missing any thing?


Thanks
Milind
