It looks like UHD is recognizing you daughterboard just fine, hence the
string "Name: TVRX2 (0x0046)" in the probe output.

I think you are trying to use the old libusrp1-gnuradio driver, when you
should be using the gr-uhd source and sink blocks:

Thanks for your reply Josh,

So the instructions are:

(1) Use the script

OR

(2) - run "git clone http://gnuradio.org/git/gnuradio.git",

    - Follow the Gnuradio build guide: http://gnuradio.org/redmine/projects/gnuradio/wiki/BuildGuide,  

    - check the dependencies and make sure that gr-uhd is enabled in the Gnuradio source tree.

I'm positive I did (1) on one of our systems and (2) on another one. To the letter. Neither of them work.

I believe the libusrp1-gnuradio driver was installed along with the gr-uhd one.

Is there a way to figure out which library is being used by UHD?

Is there a way to specifically tell UHD which source and sink blocks should be used?

Thank you,

Dmitry Shatskiy.
