Quadrature output for A:AB is correct, but it's not switching real and imag for A:BA. I'm going to start a new thread on this. Noticed this a while back, but figured I'd wait until the major bug was fixed.

So then I checked out the uhd maint head like you but can't build it properly. What branch of gr-ettus are you using? Did you install it after installing the uhd maint head? Note: I ran into similar gr-ettus build issues when I checked out the uhd maint branch commit Michael mentioned earlier. My workaround for that was to instead the uhd rfnoc-devel branch head then modify the radio_ctrl_impl.hpp and radio_ctrl_impl.cpp files to match what was checked into uhd maint branch (commit 8922095). So I never actually got uhd maint branch to build with with gr-ettus master branch.

I’m not using the rfnoc branch; just the normal maintenance branch, but last time I messed with it, you had to do that.

I checked out the head of the uhd maint branch (commit 34c5610) and installed it (set "ENABLE_RFNOC" to "ON" in CMakeLists.txt).

Will check it tomorrow. Was able to do 100 Msps full duplex. Lou On May 11, 2018, at 19:18, switchlanez <switchla...@gmail.com> wrote: Thanks, Michael. So with the fix you referenced RFNoC: Radio now works in Rx mode but does not seem to work work in Tx mode regardless of what's connected to its input (I've tried GNU Radio's in-tree Signal Source then Null Source blocks separately). The "what(): map::at" error is resolved so there is no error message but the "TX/RX" indicator light on the X310 front panel fails to light up. Has that been fixed or is a fix in progress?

Second, yes, you can install multiple installations of UHD by setting the CMAKE_INSTALL_PREFIX different for each installation. You will have to set the PATH and LD_LIBRARY_PATH environment variables appropriately to switch between them.

Do you know if I were to install rfnoc under a different prefix would the UHD version be able to be switched between the prefixes? I'm using an older rfnoc build compatible with Vivado 2015.4 and hesitant to install the latest build and checkout that new fix if it it will overwrite the older UHD version.
