UHD 4.9.0.0 Release Candidate 1

  • Highlights / Main Changes

    • Support for USRP B206mini-i
    • Support for OBX daughterboard

  • New Features

    • OBX daughterboard and B206mini support added.
    • X3x0: Add support for the gps_iface feature. This allows sending arbitrary
      commands to the GPS module.
    • rfnoc_modtool: Add a new subcommand, make-yaml, that generates a block
      YAML file from some user inputs. When calling rfnoc_modtool add without
      a valid block YAML file, the tool will now automatically call make-yaml to
      generate a new YAML file.
    • Added support for processing multiple samples per cycle in FFT block.
    • LabVIEW/USRP: New repository containing example applications which
      demonstrate how to use NI LabVIEW with USRP devices via the UHD APIs.
      (https://github.com/ni/labview-usrp-examples)

  • API Changes

    • uhd::math::gcd and uhd::math::lcm are removed from the public
      headers. Use std::gcd and std::lcm instead if C++17 is available,
      or boost::math::gcd and boost::math::lcm if not.
    • When calling recv() on an RX streamer connected to an RFNoC device, we
      no longer artificially inflate the timeout value. The old behaviour was
      in some cases abused to detect overruns, but this is not a reliable method
      and is now explicitly declared unsupported.

  • Bug Fixes

    • RFNoC
      • Calling recv() on an RX streamer connected to an RFNoC device with a
        zero timeout value now correctly returns immediately.
      • rfnoc-gain: Moved the fpga/ subdirectory under rfnoc/. This way, the
        directory structure inside the OOT module is identical to the directory
        structure after installation.
    • X410:
      • Fixed NCO reset mechanism that caused ADC self-cal errors to occur during
        reopening of a UHD session when timed tune commands were previously used.

  • Removals / Deprecations

    • Removed tools/uhd_dump. This tool is obsolete, the USRP X3x0 is not even
      compatible with it any more. Dumps can be recorded and analyzed with wireshark
      and the UHD dissectors in here.
    • Removed network_relay example.

  • Validated OS Environments
    (Versions for build and runtime dependencies can be determined from the
    docker container definitions in the UHD repository at .ci/docker/...)

    • Linux:
      • Ubuntu: focal (20.04), jammy (22.04), noble (24.04), plucky (25.04)
      • Fedora: 40, 41, 42
    • Windows: 10 22H2, 11 23H2
    • MacOS: Sequoia (15.2)

    Binary installer installers for Linux and Windows are available at
