Hi,

I've built a pxa255usbfn driver with mass storage and to test it i've =
included the ramdisk driver
on my device. Eventually i will use PCMCIA flash disk. All drivers are =
loaded at boot. I connect the
ce device to PC host so was hoping to see the Ramdisk storage card as =
disk, pc sees device as mass storage
device in Device manager but says no drivers loaded! Any way no disk =
shows up in Windows explorer.

I have following debug output during boot. My ramdisk seems to be =

on how to get this to work. The mass storage fn driver seems to be =
seeing the disk but the PC can't

ms,

Try with the entires in ur platform.reg file. This should remove
the storage entries and add the ramfmd to ur OS image.

in ur <platform>.bat file include the below entry:

I have found setting the Removable flag =3D 1 in the USBMSFN settings =
cured the=20
problem and i can see device as a folder but not sure why this is.
