I am using GNURadio and trying to get the Fosphor display working with my new X410. Similar to the post I found below, I can build the firmware but don't have the qtgui_fosphor_display available to put in a flowgraph in GNURadio. Here are my version details:
UHD 4.6.0.HEAD-releaseGNURadio v3.10.8.0Python 3.10.2
I've tried a checkout of main from the time frame of the post below (I grabbed 42b70d3 Jul 14, 2023), so my directory /gnuradio/gr-qtgui/lib contained the file fosphor_display_impl.cc and several other fosphor-related files. Build completed successfully, but I still didn't have the block in GNURadio.
Also tried checking out and building v3.11.0.0git where things have been renamed rfnoc_f15. Same results - build completed successfully but I don't have a block to insert in the flowgraph to get my spectrum and waterfall display.
Did a miss a step to pull the block into GNURadio once it's built? Do I need to create an OOT Module with the fosphor (or rfnoc_f15) code? I have minimal experience with the X410 and GNURadio so I may just have a gap in understanding.
I've attached the flowgraph I am trying to use as a starting point and the .yml file I used to build the firmware.

It's currently in main but not in any release since it isn't well vetted. You can see the controller here: https://github.com/gnuradio/gnuradio/blob/main/gr-qtgui/lib/fosphor_display_impl.cc So it's currently in the qtgui components - so build the latest UHD (tagged is fine) and the latest main GNU Radio to get what you need. I've had issues getting the GUI to be responsive when the fosphor display is going, but I haven't spent a lot of time debugging it. I am attaching the yml for the rfnoc_image_builder X310 build I did that goes with the flowgraph. Brian
