Re: FlashROM as a disk in CE 5.0

Hi Gouri,
I am curious about what you changed to get this working.
It looks like you changed the MountFlags registry setting in the profile,
but according to MSDN, this is deprecated as of CE 5.0. Instead,
MountBootable (which you added) tells the hive which driver is needed to
access the registry at bootup. You also added Flags of 1000, which tells
the system to load your driver in the first boot phase (and only in the
first phase).
related MSDN pages are:
http://msdn2.microsoft.com/en-us/library/aa916269.aspx
and: http://msdn2.microsoft.com/en-us/library/aa914710.aspx
It looks like you doubled the BlockSize and WriteBufferSize...I presume this
is to account for two devices interleaved.
So I'm guessing you told the HIVE how to load the registry when booting from
flash and this fixed the problem...
Best regards,
Gary

Probably becuase it is XIP from flash. So instructions running from

it is loading our Flash driver dll also.
After this only it is hanging.Do u have any idea why it is hanging
here.
Thanks,

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...

Gary

not getting up.
Am i missed any thing.Plesse Guide me.

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

5.Runtime image can be larger than 32 MB.
and i have modified the Project.bib and project.reg as i said
earlier.But
why it is not coming in the loading list i didn't get.Am i
missing
anything.Please help me.
Thnaks,
Gouri.

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
