Thanks Josh.
Found that line of code.
Following your advice, I have tried both methods you mentioned and have
run into problems for both.
For the first one, I have followed the install instructions for microblaze
toolkit given on the gnuradio wiki and after setting the path, I tried to
configure. usrp2-firwmare failed and the reason that wwas showned was that
they failed to detect mb tools.
Try running mb-gcc from the command line first. See if you can do:
mb-gcc --help
Once that works, you run the commands (configure.gnu -- not configure --
weird I know...):
cd usrp2/firmware
./bootstrap
./configure.gnu
make
Since you are building FPGA images (I assume you have a copy of ISE),
then you may just want to use the mb-gcc that comes with Xilinx EDK.
I then tried to install UHD and I managed to copy the firmware and FPGA
configuration into the card and I managed to verify by pinging the USRP2.
good
I am however unable to run any of the cpp files even as root as permission
is denied.
Why are you trying to execute c++ files?

I am asking for help if there is anyone who has a modified binary firmware
file compiled for the gnuradio version that I can have. I also would like
to ask for help to compile a modified FPGA image.
Thanks
I believe that the gnuradio usrp2 driver defaults to using only RXA for
the BasicRX board. This can be changed by modifying this value in
firmware for lib/db_basic.c to be "true" for the following line:
.base.is_quadrature = false,
As an alternative, I recommend trying the UHD:
http://ettus-apps.sourcerepo.com/redmine/ettus/projects/uhd/wiki The
basic board defaults to using both RXA and RXB, and the selection is
software configurable.

Hi all,
I started testing my USRP2 at a lower frequency. I have a function
generator generate a 10MHz sine wave on RX-A and RX-B.
However, I am unable to see the signal when I run usrp2_fft.py. To
confirm, I disconnected the signal from RX-A and still nothing. I can
only
trace the signal as far as the signal transformer as the ADC is under the
Basic-RX board.
Is the USRP2 only able to receive on RX-A or is the board defective?
Thanks in advance.
