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: http://code.ettus.com/redmine/ettus/projects/uhd/wiki#Gnuradio-UHD ************************************************************************************ 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.
