Hi,
Hi
Thanks for your response. I want to tell few more things about our implementation.
Actually we are planning to simulate (but not implement) the file system and implement the SCSI transparent command set decoder. When ever a file is sent to the USB mass storage device, we will be taking the content of that file to use for our application. The actual application does not require all the features of a Mass Storage Device; we just want it to look like a Mass Storage Device for transferring the data in the form of a file and for some other usage.
You can also use USB DFU for this where you can transfer files to RAM or NAND partitions. DFU is not yet supported in Denx's uboot tree but is Available in openmoko's tree [http://git.openmoko.org/?p=u-boot.git;a=summary]. You will have to port back DFU feature from openmoko to Denx's tree.
Thanks for the hint Ajay. Let me add that DFU is also a "standard" protocol: http://www.usb.org/developers/devclass_docs/DFU_1.1.pdf
So many people will be able to enjoy this in addition to solving this very specific problem of Yogesh.
Cheers Detlev
