Problem with code changes in digital-bert for USRP2

Hi All:

I have made changes in the digital-bert folder of GNURadio-3.2.2 for my
system to work with USRP2. I have been able to successfully transmit
using
the benchmark_tx.py script. However even after making changes in the
receiving scripts (benchmark_rx.py & usrp_receive_path.py) on the same
lines
as transmit, I get the following error when I execute it:

gnuradio-3.2.2/…/digital-bert>sudo ./benchmark_rx.py -f 2.4G

Traceback (most recent call last):
File “./benchmark_rx.py”, line 120, in
tb = rx_bpsk_block(options)
File “./benchmark_rx.py”, line 56, in init
self._receiver =usrp_receive_path.usrp_receive_path(options)
File
“/home/winuser/gnuradio-3.2.2/gnuradio-examples/python/digital-bert/usrp_receive_path.py”,
line 63, in init
self._setup_usrp_source(options)
File
“/home/winuser/gnuradio-3.2.2/gnuradio-examples/python/digital-bert/usrp_receive_path.py”,
line 83, in _setup_usrp_source
self.u = usrp_options.create_usrp_source(options)
File
“/home/winuser/gnuradio-3.2.2/gnuradio-examples/python/digital-bert/usrp_options.py”,
line 80, in create_usrp_source
usrpx=options.usrpx,
AttributeError: Values instance has no attribute ‘usrpx’

My scripts are located in the following folder:

http://www.esnips.com/web/gnuradiodigital-bert/

I am working towards making all the scripts compatible with USRP2. I saw
the
introduction of “usrp_transmit_path” and “usrp_receive_path” wrapper
functions in 3.2.2 and would be using the same for converting other
applications (ofdm, sprectrum sense etc.) as well.

Is there anybody else who is working on the same problem ?

Any help on this issue would be greatly appreciated.
