Hi Vidyadhar,
You need to burn the fpga image on to the usrp 2. You
can either run the command given above or go to
cd /usr/local/share/uhd/utils from your home folder and then open
usrp_n2xx_net_burner_gui.py and then run in terminal. Then you get a gui
with two fields Firmware Image and FPGA image.

Select usrp_n2xx_fw.bin for Firmware image and usrp_n2xx_r4_bin for FPGA
image. Both of these files are in images folder of uhd.

Then burn these images. That should solve the problem.
