Thanks for the information, but this is for testing purposes only. We have
an application that runs on Windows Mobile 2003, and uses third party
software that utilizes temporary file storage while processing. When we port
to Windows Mobile 5.0, the application slows down, and eventually crashes
which we suspect is due to the persistent store of files in Windows Mobile
5.0, and the operation of the compaction thread as explained in the following
link (search for filesys.exe to get to the right spot).
http://blogs.msdn.com/windowsmobile/
The quickest way for us to test this theory by setting up a RAMDISK, and
pointing our third party software there, so that it can thrash away at
memory. Our long term solution is to get them to modify their software to
use RAM, or to get our PPC vendor to include a RAMDISK in their WM50 offering.
That said, I have successfully built ramdisk.dll, and have created
ceramdrv.exe, but am unable to execute ceramdrv.exe on my device. Any
thoughts?

Thank you all for this informative posting. I am also trying to get a
RAMDISK to use in my Windows Mobil application. I have a 120 day trial
version of the Windows CE 5.0 platform builder, and built a representative
version of the WM5.0 OS I am using. I dragged and dropped the RAM and ROM
File System into my catalog, as noted in this thread. I checked that all
of
the dependencies it requires are set, and I re-built (build and Sysgen)
the
OS. I see that the RAMDISK library files (ramdisk_lib) were re-built in
the
directory C:\WINCE500\PUBLIC\COMMON\OAK\LIB\ARMV4I\RETAIL, but I don't
have a
RAMDISK.DLL anywhere??? Is there something I am missing?
Thanks for any help.

You most likely don't want BINFS (which is the Binary Rom Image File
System
component you described). This is a specific file system that is used to
page the operating system from a block device. It might automatically
include components from the RAM Disk block driver since it is probably
tested with that, but is otherwise completely unrelated.

Hi
I have successfully added ramdisk into win ce. I needed to add the
"Binary
Rom Image File System" component. Also there is ceramdrv maned folder
below
ramdisk. If added as an application, upon execution, it also creates a
ramdisk.
Thanks everyone.

Hi
Actually, I wanted to ask about the RAMDisk only. I have added
thesysgen
variable, SYSGEN_RAMDISK, and also included the ramdisk.dll into my
nk.bin
along with the registry entries. But Windows CE doesnot mount the
ramdisk
on
startup although i've given in the registry as autoload. In the
storage
manager controlpanel applet, it also lets me format the ramdisk and
mount
it,
but still it does not appear in the folder list under "my device".
Actually my main problem is that I have strataflash which works fine
but
when it gets full, it doesn't let me delete any files and becomes
almost
unusable. I have to reformat it to use it but that deletes all the
files
present. I wanted ramdisk just to check if this is a problem with the
file
system or my flash only. Other than that my flash driver works fine.
Would
you please help me on that.
Thanks

Note that this is also referred to as the object store, and is a

of
RAM
for a storage area and mount any file system you like on top of it.
For
that, you'll need the RAMDISK driver from the public tree.

Drag over the RAM and ROM File System component from the catalog
under
File Systems to your OS design.
See File Systems under the Windows CE help documentation.
