As Ettus Research has announced the UHD software support for USRP1 and USRP2 is stabilizing. There are many long awaited features that will become part of this next generation code, and the question has come up about the future of the current GNU Radio support for this hardware.
We will address this in three stages. Firstly, the current libusrp/libusrp2/gr-usrp/gr-usrp2 components will become part of the 3.3 stable release series. This is intended as a measure to support existing user code that depends on this functionality, and we will maintain this with bug fixes as needed. The GNU Radio release tarballs will include the host and firmware code, and the gnuradio.org website will host binaries for the associated FPGA image and firmware images. The corresponding FPGA source code will continue to be hosted/distributed by Ettus Research. This gives long-term support for existing users who do not plan to upgrade. Secondly, during the 3.4 development series, we will incorporate the gr-uhd GNU Radio host code blocks, and begin transitioning our examples, demos, and other code that uses gr-usrp/gr-usrp2 to use gr-uhd instead. This will be gated by available functionality/stability of the Ettus Research code. Finally, also during the 3.4 development series, we will extract the libusrp/libusrp2 code (but not gr-usrp or gr-usrp2) into its own stand-alone distribution and remove it from GNU Radio proper. This will give developers the choice of installing the "FSF" version of the libraries or the Ettus Research libraries (or both) as desired, and GNU Radio will install gr-usrp/gr-usrp2 and/or gr-uhd depending on what was detected during configuration. It is intended that as of stable series 3.4, future GNU Radio development will continue around the Ettus Research UHD code features, and only critical bug fixes in the stand-alone FSF library be considered. Please feel free to respond with any questions/concerns.
