Hi there,
I am attempting to set up UHD with RFNOC to cross compile on my E310 sg1, where I ran into a bit of an issue while trying to run the example files. I followed this guide to setup the environment: https://kb.ettus.com/Software_Development_on_the_E3xx_USRP_-_Building_RFNoC_UHD_/_GNU_Radio_/_gr-ettus_from_Source There were also errors in uhd_usrp_probe, however they were identical to those talked about here: http://lists.ettus.com/pipermail/usrp-users_lists.ettus.com/2017-March/023950.html Jonathon's response in that thread reassured me that UHD would still work despite the error messages in uhd_usrp_probe and tested out the example file stated in the guide. So my question is: Is there something I need to correct with my build? Or is this just a result of the assertion errors from uhd_usrp_probe? I pasted the output I received below: root@ettus-e3xx-sg1:~/newinstall/usr/lib/uhd/examples# ./rx_samples_to_file --freq 100e6 --gain 0 --ant TX/RX --rate 1e6 --null Creating the usrp device with: ...
