Here is the error.

RuntimeError: RuntimeError: 
Please update the firmware and FPGA images for your device.
See the application notes for USRP2/N-Series for instructions.
Expected FPGA compatibility number 7, but got 6:
The FPGA build is not compatible with the host code build.

I re-run the script in the same PC.I went to the folder
I saw a tag 003.001.002 while the latest release is 003.002.003 at

In another PC I re-run the script and before that I deleted that UHD
folder.Now the tag is missing.Cant say which version.

Anyways my problem has solved after I burnt my SD card with the latest
release :)
