Your output indicates that you're executing UHD v.3.10.0.3, not version 3.14.1, so you must have multiple versions installed.
Go to /usr/local/lib (or wherever you installed UHD on your machine) and make sure it looks something like this when you type in "ls -l uhd*": lrwxrwxrwx 1 root root 16 Sep 16 11:03 libuhd.so -> libuhd.so.3.14.1 -rw-r--r-- 1 root root 15583328 Sep 16 11:01 libuhd.so.3.14.1 On Thu, Sep 19, 2019 at 3:55 PM David Smay via USRP-users < usrp-users@lists.ettus.com> wrote: > Hello, > > I recently did a clean installation of UHD 3.14.1 and gnuradio 3.7.13.5 on > Ubuntu 18.04 LTS, following the steps outlined in the Ettus knowledge base > for installation from source. > > The installation worked great, and I started experimenting with the > example programs installed with UHD (located in /usr/lib/uhd/examples/). > At first they ran correctly and I was able to run the gpio and > benchmark_rate programs without issue, getting the normal expected output > for my b205mini-i. > > Without making any changes to the system, and in the same shell session, > all of a sudden the example programs all started consistently generating > errors when I tried to run them: > > dsmay4@UbuntuPrecision7530:/usr/lib/uhd/examples$ ./benchmark_rate > --rx_rate 10e6 > linux; GNU C++ version 7.3.0; Boost_106501; UHD_003.010.003.000-0-unknown > > > > UHD Warning: > EnvironmentError: IOError: Could not find path for image: > usrp_b200_fw.hex > Using images directory: <no images directory located> > Set the environment variable 'UHD_IMAGES_DIR' appropriately or follow > the below instructions to download the images package. > Please run: > "/usr/lib/x86_64-linux-gnu/uhd/utils/uhd_images_downloader.py" > Creating the usrp device with: ... > > UHD Warning: > EnvironmentError: IOError: Could not find path for image: > usrp_b200_fw.hex > Using images directory: <no images directory located> > Set the environment variable 'UHD_IMAGES_DIR' appropriately or follow > the below instructions to download the images package. > Please run: > "/usr/lib/x86_64-linux-gnu/uhd/utils/uhd_images_downloader.py" > Error: LookupError: KeyError: No devices found for -----> > Empty Device Address > > This is quite strange as my uhd_images_downloader isn't installed to that > directory, but it does run just fine. uhd_find_devices and uhd_usrp_probe > run fine and indicate no problems with the radio itself.
