Re: FMD driver problem - Unable to add FlashDisk to my OS Design

Tech-Archive recommends: Repair Windows Errors & Optimize Windows Performance

Hi,

The driver still doesn't work. But I have a new idea, what the problem could
be. My StrataFlash is asynchron connected to the PXA270 CPU. But there are
two Read opeartions possible for example: Asynchronous Page-Mode Read and
Synchronous Burst-Mode Read. How does the driver know, how the flash is
connected?

To Gary: So I think, that I doesn't need XIP.

By the way: Could anybody send me his registry settings for the stratad
driver. Then I could compare working settings with my own.

Thanks,
Andreas

Hi Andreas,
I believe XIP means raw writes with no flash driver metadata. XIP would be
used for FMD integrated in the OAL for raw binary updates. If you want to
load an executable from a flash disk, then to the FMD this will just be
another file, managed by the filesystem, and it needs the metadata.

Regards,
Gary

Hi Bruce,

the driver doesn't work, but I think that the geometrie should no be ok:

[HKEY_LOCAL_MACHINE\Drivers\BuiltIn\StrataFMD]
"Dll"="stratad.dll"
"Order"=dword:2
"Prefix"="DSK"
"Ioctl"=dword:4
"Profile"="MSFlash"
"IClass"="{A4E7EDDA-E575-4252-9D6B-4195D48BB865}"
"XIPEntireFlash"=dword:1
"MemBase"=dword:9AA00000
"MemLen"=dword:100000
"BlockSize"=dword:20000
"WriteBufferSize"=dword:C ; determined from CFI
"SectorSize"=dword:200
"IsPairedFlash"=dword:0 ; 16 bit Data-Bus width

Do you know sonthing about the following registry settings?
1. XIPEntireFlash: I will not start WinCE at the flash. But I will start
executables from the FlashDisk in Windows. Do I need XIP for this?
2. MountFlags
([HKEY_LOCAL_MACHINE\System\StorageManager\Profiles\MSFlash]):
I will not boot from the Flash, but I will use the Flash for Hive Based
Registry. Is the setting 6 for "MountFlags" ok? (This should mount the
partition at the root as a bootable partition.)
3. LoadFlags
([HKEY_LOCAL_MACHINE\System\StorageManager\AutoLoad\MSFlash]):
LoadFlags 0x01 == load synchronously. What means this?

Thanks,
Andreas

Ok, I will check the data sheet because of the geometry.
But one other question. What is the SectorSize? Why do I need this
registry
setting?

Thanks,
Andreas

Actually, I beleive that the data sheet is wrong about that - or at
least
inconsistent. Check the Geometry (I think) in the data sheet. But
the
actual value will depend on how your driver uses it. I have modified
mine
to support P30, so it is considerably different. Mine calculates the
write
buffer size based on the information that it reads from flash.

I would say that 0x20 for the WriteBufferSize is correct, because a
buffered
program command is followed by up to 32 words of data at P30 Flash
(from
the
datasheet P30 StrataFlash).

But I have tried 10 (0xA) and I get the same error mesages:

By the way, I have no paired flash. I have only 16bit databus width.
Have you another idea?

Double check WriteBufferSize - it should be n, where the actual
write
buffer
size is 2 ^ n (2 raised to the power of n) multiplied by 2 if

is set.

I think that n for P30 is 10 (0xA)

Hi Bruce,

I don't use the smaller blocks at the beginning of the flash. I
will
split
my flash in two parts. The first for the Image: 0x0000_0000 -
0x00FF_FFFF
and
the seccond for the FlashDisk: 0x0100_0000 - 0x01FF_FFFF
But it doesn't work. So I think the failure is in the registry
settings
or
in the OEMAddressTable.

Yes, it can be modified to support P30.

Giving it more thought, you probably can get it to work with P30
simply
by
avoiding the smaller blocks. That is set the start address or
size
to
keep
the flash disk out of the smaller blocks.
