FMCOMMS5/ZCU706 on remote GNURadio


After playing around using Kuiper linux on the board I want to setup a remote connection. I want to run gnuradio-companion on my windows PC through WSL2 and connect it to the ZCU706 via ethernet. The ethernet setup for local connections is working and already installed gnuradio-companion using $ sudo apt install gnuradio. After that  I add to the python path $ export PYTHONPATH=/usr/local/lib/python3.10/dist-packages:$PYTHONPATH  ran gnuradio-companion as follows $ sudo gnuradio-companion. There I just added an FMCOMMS5 sink an one source an connected them. After trying to run the following error appeared: AttributeError: module 'gnuradio.iio' has no attribute 'fmcomms5_source_f32c'. Did you mean: 'fmcomms2_source_fc32'? Did I do something wrong during the installation process? I am aware of, but since installing gnuradio using the apt already has the FMCOMSS blocks and in the tutorial only gnuradio 3.7 and 3.8 are mentioned, I don't know what I have to do. 

Thanks in advance, best regards,

  • Hi Diogo,

    The IIO blocks (including the ones for the FMCOMMS5) are already provided by GnuRadio 3.10, so there shouldn't be anything to install aside (as I understand you manually installed gr-iio in /usr/local/lib/python3.10/dist-packages). You only have to install the "" package and you should be good to go.



  • Hi,

    Thanks for the response. By checking the installed packages, the one you mentioned is already installed. Is there anything else I must do?

    I also add t the python3 Path the directories where the packages would be found:

    I am really confused on what to test next. I already tried installing from GNU Radio and IIO Devices: gr-iio [Analog Devices Wiki] but it does not work. Just to clarify again. I am trying to setup a remote connection to a ZCU706 with and FMCOMMS5 running Kuiper linux, from a WSL2 Ubuntu running on a windows PC. I want to design on gnuradio on WSL2 and then run directly on the WSL2 but getting the data from FMCOMMS5. 

  • I think you installed gr-iio and it conflicts with the libgnuradio-iio package that you installed with the package manager.

    What I would try, is uninstall gnuradio and libgnuradio-iio, remove anything related to gr-iio in /usr/local, and install gnuradio again.
