AM335x Boot over USB issue

Other Parts Discussed in Thread: AM3352

Hi,

Currently we are using AM3352 in our custom board.
We have succesfully tested the booting over UART but having difficulties in booting over USB0.

Do we have any procedure for booting AM335x over USB like the one described below for UART?
http://processors.wiki.ti.com/index.php/AM335x_U-Boot_User's_Guide#Boot_Over_UART

As per the TRM manual:
During USB boot,
"ROM implements as RNDIS class driver, so the device enumerates as an ethernet port.
and download the boot image using any standard TFTP server application standard TFTP server application"

So we are trying with a standard TFTP server,
the target board seems to be trying to get the files but fails in between.

Below is the log from the TFTP console, which says it cannot find the path specified.

---------------
Read request for file<>.....
File<>:error 3 in system call createfile the system cannot find the path specified
--------------

Please let us know what sort of file(.bin?) should be kept in the TFPT server directory
and what should be the name of the file.

Regards
Prad
