Re: FlashROM as a disk in CE 5.0

Hi Gouri,
Are you saying that if you download to SDRAM, you no longer have the "block
0 locked" error? Did you work around that to allow the FAL to format the
flash?

As far as behavior of loading in SDRAM versus loading from flash, is the
bootloader jumping to the right place to load your code from flash? It
looks like the bootloader tries to jump into the OS code and doesn't get
very far...

I have noticed that when downloading the OS to RAM, a component or
application can be loaded automatically from the flatrelease directory, even
though it was not included in the image. Maybe you have some component that
is not properly included in nk.bin, so it loads for you when downloading to
RAM, but when booting from the flash, it doesn't have that same connection
to the flatrelease directory...

Regards,
Gary

Hi Gouri,
Are you saying that you set a breakpoint in FMD_Init and didn't hit it
because the FMD is not getting loaded?
In that case, your MemSize and MemLength aren't being looked at yet.

You mentioned that you included FAT and it looks like you selected TFAT
format. Have you included TFAT? I think that at least in CE 4.2, TFAT
required an additional dll. Maybe you could check the makeimg output for
the TFAT dll.

Also, I would check reginit.ini and ce.bib in the flatrelease directory
to
make sure your reg and bib changes got included.

If all the components are included correctly, you should be able to see
FMD_Init getting called.

Gary

Hi Gouri,
Have you tried debugging FMD_Init to see if the flash driver is being
loaded? And if so, what registry values it finds for MemBase and
MemLength?

Hi experts,

Currently workin on proving FMD support for Intel Strata NOR
flash
(K3
family of 32 MB) on pxa27x
platform with WinCE 5.0 .I amfacing a strange problem ,
wherein
i
not
able to mount the FAT
partition. The driver i am using is the sampe FMD code given
by
Microsoft for
NOR flashes( strata folder in MSFLASHFMD).I am not able mount
the
"NOR
folder" at boot time.

for this i have included the SYSGEN_MSFLASH_STRATAD=1 in the
environmental variables and
i included the stratad.dll in project.bib like

stratad.dll $(_FLATRELEASEDIR)\stratad.dll
NK
SH.

I have added the Registry settings to Project.reg file like

[HKEY_LOCAL_MACHINE\Drivers\BuiltIn\StrataFMD]
"Dll"="stratad.dll"
"Order"=dword:2
"Prefix"="DSK"
"Ioctl"=dword:4

"Index"=dword:1
"BlockSize"=dword:20000
"WriteBufferSize"=dword:20
"SectorSize"=dword:200
"IsPairedFlash"=dword:1


; Override names in default profile
[HKEY_LOCAL_MACHINE\System\StorageManager\Profiles\MSFlash]

"Flags"=dword:00100024
"Util"="fatutil.dll"
"Paging"=dword:1
"CacheSize"=dword:0
"FormatTfat"=dword:1

I have updated the oemaddrtab_cfg.inc to

DCD 0x9CA00000, 0x00000000, 26 ; MAINSTONEII: nCS0:
Boot
Flash
(26MB).

DCD 0x9E400000, 0x01A00000, 6 ; MAINSTONEII: nCS0:
Storage (
6MB).

Now i am downloading the Image to Flash.But i didn't find any
Nor
flash
folder and i didn't find the anything
in the Storage manager applet which is in Control panel.

And one more thing i have added Fat file system and Partition
driver
to my
OS.If i add the Hive registry to os
Image is not Up thats why i have removed Hive registry i didn't
find
any
Nor
flash folder and i didn't find the anything
in the Storage manager applet which is in Control panel.

Is there anything is missed.Please help me in this regard.

Thanks,

Gouri.
