Hi,

Thanks for your input on our issue.

The problem is, in our custom board there is no USB OTG port.  For 
programming, we are using JTAG debugger.
With Linux-3.0.35 based BSP we are able to program/boot the target.  
But  imx-3.10.17 GA based BSP we are not able to boot/program the target.

Thank You,
Regards,
Ansari
