UHD v4.1.0.5 Release

Apart from some minor enhancements and bugfixes, this release adds support for the NI Ettus USRP X410 with module revision E and motherboard revision G, which uses a different CPLD on the motherboard than previous revisions. Please note that the X410 filesystem image that ships with versions of UHD prior to v4.1.0.5 will not support newer revisions of the USRP X410; thus, we strongly recommend that all USRP X410 users upgrade their devices with the filesystem that ships with v4.1.0.5. Please refer to the instructions under 'Updating Filesystems' in the USRP X4xx section of the UHD manual at https://files.ettus.com/manual/page_usrp_x4xx.html for information on how to perform the update.

UHD 4.1.0.4 Release

This release corrects an oversight in the 4.1.0.3 release by updating the version string reported by UHD.

004.001.000.004

• uhd
  • Update version in UHDVersion.cmake

UHD 4.1.0.3 Release

This release addresses one issue in UHD regarding RX and TX antenna configuration on the ZBX daughterboard.

004.001.000.003

• uhd
  • zbx: Prevent TX antenna config from disrupting RX

UHD 4.1.0.2 Release

This release fixes some minor issues in UHD:

• Some streaming issues with the B2xx, notably good data packets being dropped in the event of an overrun and USB overflow issues when using the sc12 data type, have been resolved.
• The semantics of calling recv() on a streamer with 0 for nsamps_per_buff was inadvertently changed in a previous commit. The original correct semantics (return immediately without regard for the timeout and availability of samples) have been restored.
• Certain link establishment timeout cases could result in an exception being thrown while another exception is in flight, thus triggering process termination. The codepath triggering the errant second exception has been corrected to avoid this situation.

004.001.000.002

• b200
  • Fix overflow handling
• fpga
  • Re-order error and data packets
  • Fix sc16 to sc12 converter

UHD 4.1.0.1 Release

The UHD 4.1.0.1 release addresses a few bugs that slipped their way into UHD v4.1.0.0:

• The revision compatibility check for ZBX hardware (the X410 daughterboard) was broken, causing MPM to fail to start with ZBX revisions B or C.
• A missing include caused compilation failures on certain compilers when testing is enabled.
• UHD 4.1 would fail to build with using Boost 1.76.0.

004.001.000.001

  • remove redundant include
  • correctly set and unset any CMAKE_REQUIRED variables

UHD 4.1.0.0 Release

We are proud to announce the release of UHD 4.1! The marquee feature of UHD 4.1 is support for the new NI Ettus USRP X410, a new generation of radio providing the highest performance of any USRP to date. Along with X410 support, UHD 4.1 also brings usability and stability enhancements to UHD and to the entire stable of NI Ettus USRP devices.
