Gangadhar,
Make sure you have the boot switches setup to boot from USB, also check if your rev of the hardware support boot and flash from USB. You can check that with the expert in the Sitara forum.
That screenshot above contain no valuable information, please attach the ipv4 setup instead.
To debug and see whats going on on the target side, you can connect your PC's com port to the target using a null modem cable.
