Hey everyone, I've followed this guide for setting building the repos needed to develop with RFNoC on the E310 https://kb.ettus.com/Software_Development_on_the_E3xx_USRP_-_Building_RFNoC_UHD_/_GNU_Radio_/_gr-ettus_from_Source
But when I get to the step for uhd_usrp_probe I'm given the output I'll post at the end of this email. I had read where previous people asked about this behavior before and people said it's a known issue and that it shouldn't affect any software. However, when trying to run the example programs in the guide, such as ~/newinstall/usr/lib/uhd/examples/rx_samples_to_file --freq 100e6 --gain 0 --ant TX/RX --rate 1e6 --null I get the same 'Exception caught in safe-call' messages and a final error of: Error: RuntimeError: On node 0/FIFO_0, output port 0 is already connected. I have also tried different commits as per the suggestion in other mailing lists. No luck though... Any ideas is appreciated! Thanks! -Paul Sorensen root@ettus-e3xx-sg3:~# uhd_usrp_probe [INFO] [UHDlinux; GNU C++ version 4.9.2; Boost_105700; UHD_4.0.0.rfnoc-devel-409-gec9138eb] [INFO] [E300] Loading FPGA image: /home/root/newinstall/usr/share/uhd/images/usrp_e310_fpga_sg3.bit...
