Hello All
I seem to be receiving an a uhd error that is causing flowgraphs to
stop when trying to send and receive using the USRP X310. Now, I'm
receiving the same error shown below when running the "uhd_usrp_probe"
command. Not quite sure where this error is coming from but I see
rfnoc in the last line of the printout below which leads me to believe
that rfnoc could have something to do with the error. However, I'm not
working with the rfnoc branch of uhd. I believe someone else who was
using the device before me may have been using rfnoc. So, if this is
indeed the issue, isthere a way to rid the fpga of rfnoc and use a
regular, up to date image? o,
I'm working inside of a VM running Ubuntu 16.04 LTS. I'm using

Use:
uhd_image_loader --args type=x300
Assuming that you have already downloaded matching image files with:
sudo uhd_images_downloader
