update: as far as I can tell uhd_images_downloader no longer tells the user where on Ettus's server it looks for the files and even with an internet connection it doesn't grab the RFNoC images. However, I was able to look inside the uhd_images_downloader.py file itself and piece together the new image path ( http://files.ettus.com/binaries/cache/e3xx/) and build-specific image file name. There I found the correct RFNoC images, moved them the E310, and uhd_usrp_probe will now list the RFNoC capabilities just before it gives the string of errors and closes. rfnoc_rx_to_file and rx_samples_to_file work.
I haven't yet been able to get the old version of gnuradio running on the pc side to generate the python script to test the window or fft functions on the pre-compiled images. A stock fpga image (not RFNoC) build with Vivado Webpack from the instructions in fpga-src seemed produce a working image. The image made following the instructions in "Getting Started with RFNoC Development" using ./uhd_image_builder.py window fft -d e310 -t E310_RFNOC -m 5 --fill- with-fifos (my radio too old for sg3) did not work. It gives the error: root@ettus-e3xx-sg1:~/newinstall/usr/share/uhd/images# uhd_usrp_probe --args='fpga=usrp_e310_fpga_RFNOC.bit' [INFO] [UHD] linux; GNU C++ version 4.9.2; Boost_105700; UHD_4.0.0.rfnoc-devel-702-geec24d7b [INFO] [E300] Loading FPGA image: usrp_e310_fpga_RFNOC.bit...
