Re: Is there anyone use Spansion Nor flash?

Hi,

I tested the NOR Flash folder, found that if the files stored in the folder
are .exe or some other binary file, these files will be destroyed, if I just
store data files such as .txt .dat .log files, these files will be OK. I do
not know why?

Hi,
It sounds like code is trying to execute from the flash when FMD_Init is
called. nk.bin must be shadowed to RAM for this method. If you'd like to
partition flash for XIP, I suggest licensing SSP from Spansion, which
includes TrueFFS block driver. A WinCE filesystem (FAT, TFAT, etc) can be
used with the TrueFFS block driver.

You can submit a request at:
http://www.spansion.com/flash_memory_products/support/ses/ask_spansion.html

and for the "Type of Inquiry" field, please select "Software Licensing and
Distribution".

Best regards,
Gary

Hi Gary,

I have already got the updated FMD from you. Thanks a lot!
My nor flash starting address is 0xC8000000, and I set
"CodeSizeAtStart"=dword:00000000 and "CodeSizeAtEnd"=dword:1800000 to mask
the Eboot and NK.bin resident in Nor Flash.
If I set "MemBase"=dword:C8000000 (which is the real starting address of
Nor), Wince can only run in RAM, when I flash it to Nor, it can not start
and
stops in init FMD, I don't know why. But when I set
"MemBase"=dword:C9400000
(this address skips the EBOOT and NK.bin space), Wince can start and I can
see the NORFLASH folder in my Wince. But I can not format this space in
control panel/storage manager, and some time the executable files in this
folder can not be executed, an error dialog appeared, I don't know why.
And I
tried to use HIVE register system in my Wince, and the system became very
slow.

My register about this Nor flash is in my first post, my platform is
freescale i.mx21 ADS board. Thanks a lot!

I don't think the FASL FMD that ships with CE supports the CodeSizeAtEnd
registry key.
Is C9400000 the real starting address of the flash? The real starting
address should be used and the MemLen is ignored. The length of the
flash
is detected from CFI.

Regards,
Gary

Hi,

I use Spansion Nor flash in my board. According to the service support
of
Spansion, I use the driver locate in
:\WINCE500\PUBLIC\COMMON\OAK\DRIVERS\BLOCK\MSFLASHFMD\FASL\FASLD, and
set
the
register as below:
[HKEY_LOCAL_MACHINE\Drivers\BuiltIn\FASLD]
"Dll"="fasld.dll"
"Order"=dword:2
"Prefix"="DSK"
"Ioctl"=dword:4
"Profile"="MSFlash"
"IClass"="{A4E7EDDA-E575-4252-9D6B-4195D48BB865}"
; "MemBase"=dword:C8000000
"MemBase"=dword:C9400000
"MemLen"=dword:200000
"CodeSizeAtStart"=dword:00000000
"CodeSizeAtEnd"=dword:1800000

; Override names in default profile
[HKEY_LOCAL_MACHINE\System\StorageManager\Profiles\MSFlash]
"Name"="MSFLASH for FASL FLASH"
"Folder"="NORFlash"

[HKEY_LOCAL_MACHINE\System\StorageManager\AutoLoad\MSFlash]
"DriverPath"="Drivers\\BuiltIn\\FASLD"
; LoadFlags 0x01 == load synchronously
"LoadFlags"=dword:1
"Order"=dword:4



; Override names in default profile
[HKEY_LOCAL_MACHINE\System\StorageManager\Profiles\MSFlash]
"DefaultFileSystem"="FATFS"
"PartitionDriver"="mspart.dll"
"AutoMount"=dword:1
"AutoPart"=dword:1
"AutoFormat"=dword:1
"BootPhase"=dword:0
"Name"="MSFLASH for SPANSION"
"Folder"="NORFlash"
"MountFlags"=dword:2
;"MountAsBootable"=dword:1

[HKEY_LOCAL_MACHINE\System\StorageManager\Profiles\MSFlash\FATFS]
"FriendlyName"="FAT FileSystem"
"Dll"="fatfsd.dll"
;"Flags"=dword:00000024
"Paging"=dword:1
"CacheSize"=dword:0
"EnableCacheWarm"=dword:0
"EnableCache"=dword:1
"MountFlags"=dword:2

It can works, but some time the executable files in the NORFlash folder
can
not be executed, and these folder also can not be formatted!
And I tried to use HIVE register, but failed.
Is anyone use these driver? Did you meet the same problem? Thanks a
lot!
