    in this UHD release.

UHD 4.9.0.0

• 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)
  • Improved RFNoC OOT Block support:
    New repository containing official RFNoC OOT Blocks
    (https://github.com/EttusResearch/rfnoc-oot-blocks)
    • Added new RFNoC Aurora Block for TX and RX remote streaming applications
      to and from Aurora capable compute nodes like FPGA Coprocessors.
  • Enhanced the UHD Windows installer to automatically install Windows
    driver packages into the OS, eliminating this manual post-installation
    step for B-Series USB devices.

• 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 This tool is obsolete, the USRP X3x0 is not even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

  of binary Python bindings for Windows though PyPI

New Features

• Image Builder
  • Add GRC support. This allows designing RFNoC bitfiles from GNU Radio
    Companion (GRC).
  • Improve clock connection checks and checks for duplicate connections.
  • Improve IO port compat check (e.g., check if wire widths match).

UHD 4.7.0.0

Highlights / Main Changes

• Major updates to rfnoc_image_builder (a98ce26). This change adds support for
  defining transport adapters in the image builder YAML files, adding custom
  modules, and more.
• Updated embedded OS on file system images for E3xx, N3xx, and X4xx devices
  to Yocto 4.0 (kirkstone).

New Features

• General
  • Allow installing only Python-based utilities (e.g., rfnoc_image_builder)
    by adding the ENABLE_PYMOD_UTILS option to CMake.
  • Added ability to query dot representation of RFNoC graph
• Python support
  • Added DRAMReceiver class and amend rx_to_file.py example to use new class.
    This supplements the DRAMTransmitter class and simplifies using the DRAM-backed
    RFNoC replay block to when signal bandwidth exceeds available streaming bandwidth.
• CMake
  • We now search for a system version of Pybind11 before falling back to the
    bundled version. The system version is preferred, and the bundled version
    may be removed in a future release.
• RFNoC
  • Image builder: Major update, which adds support for defining transport
    adapters in the image builder YAML files, adding custom modules, choosing
    custom directories for build, IP, and intermediate files, building IP
    only, saving Vivado projects, and more. Image core YAML files created with
    this version are not compatible with previous versions, and vice versa!
    Also adds many more checks to avoid building bitfiles that are either
    incomplete, or valid but probably not the desired outcome.
  • Added support for defining custom register spaces in RFNoC blocks.
  • Added license checking subsystem. This allows creating RFNoC blocks that
    require a license key to operate.
  • Add device DNA feature for X310, X410, X440. This allows reading back the
    FPGA's DNA, which is a unique identifier.
• Embedded OS for E3xx, N3xx, and X4xx devices
  • With the switch to Yocto 4.0 (kirkstone), the SD card and eMMC images no
    longer pre-populate the second system partition. Refer to the device
    specific "Updating Filesystems" section in the user manual for how to populate it.
    This reduces the size of compressed .sdimg filesystem images.
• X440
  • Added new guided log info mode to provide more information about the Nyquist
    zone in which the chosen frequency is located. These additional info logs
    are enabled by default. For disabling the guided mode, add the entry
    guided_mode=false to the UHD config file in the "Global" section.
• Examples
  • rfnoc-example now also generates Python bindings for OOT block control functions.

Dependencies changes

• Increase minimum required version
  • Python to 3.7.0
  • Pybind11 to 2.7.0

Bug Fixes

• General UHD
  • Fix issue with undefined HOME or XDG_CONFIG_HOME
  • Fix compilation error with boost 1.85.0 (closed issue 740)
  • Fixed cmake find_library for UHD to fail if the library is not found

• B2xx
  • Fixed FRAC2 calculation (closed issue 684).
  • Fix DC truncation bias by adding rounding to DDC chain
• X310
  • Fix warning about duplicate reg
  • ubx
    • update ubx xcvr mode options
    • write output power to correct LO
    • Fix width of gain register
• MPM
  • Deactivate explicit DAD (Duplicate Address Detection) on int0 interface
    since this is the default behavior of systemd v250.5 (Yocto release kirkstone)
    for static IPv4 addresses if the IP address is a link local address.
  • Correct outdated mender command in prints of usrp_update_fs utility
  • No longer import from from rpc_server when already importing usrp_mpm
  • Demoted log level of ECHO send error
  • No longer print iptables errors when setting up forwarding
• X400 Platform
  • Add PPS interface to X410/X440 BSP
  • Add netlist make flow
  • Update PS DRAM speed bin
  • Replace Ethernet transport adapter
• X410
  • Set Locale for ZBX Lattice build

  • mpm
    • Add error for recurring TA node inst values
    • Fix warning about different converter rates
    • Fix MTS skip for dual-rate
    • Use greatest converter rate for sysref rate
    • Add warning for bad conv rate order
    • Enable multiple LMK VCO rates per MCR
• Examples
  • Fix rx_samples_to_file failure for multichannel fullpath.
  • Fixed bugs observing cmd argument -c in remote_rx.py example.
  • Updated tx_waveforms examples now also use timed commands during
    frequency tuning for all devices except for x410.
    On X440 this allows reproducing specified channel to channel phase alignments.
  • Consistently comment out sections in rx_samples_to_file.
