All: I'm having trouble controlling an Ettus x300 SDR using Ubuntu 22 servers.
The brief description (details below) is that I can ping the device, but I can't see it using
uhd_find_devices or uhd_usrp_probe or uhd_fft etc.I've looked around on the web for tips, but nothing is helping. In particular,
I made sure to punch a hole in the firewall using sudo iptables -A INPUT -p udp --sport 49152 -j ACCEPT Details ------- I'm using two Ubuntu 22.04.5 servers. The UHD versions are the same on each: UHD 4.1.0.5-3 One uses gnuradio 3.10.7.0 and the other 3.10.1.1.Both servers can connect to and control an Ettus x310 with two UBX daughterboards;
uhd_fft runs fine. The x310 has default (10 GB) IP address of 192.168.40.2.The x300 has one UBX daughterboard and one WBX daughterboard. When I connect either server to the x300 via 10 GB ethernet, I can ping the device at 192.168.40.4:
cmspooner>ping 192.168.40.4 PING 192.168.40.4 (192.168.40.4) 56(84) bytes of data. 64 bytes from 192.168.40.4: icmp_seq=1 ttl=64 time=0.058 ms 64 bytes from 192.168.40.4: icmp_seq=2 ttl=64 time=0.034 ms 64 bytes from 192.168.40.4: icmp_seq=3 ttl=64 time=0.048 ms 64 bytes from 192.168.40.4: icmp_seq=4 ttl=64 time=0.026 ms 64 bytes from 192.168.40.4: icmp_seq=5 ttl=64 time=0.027 ms 64 bytes from 192.168.40.4: icmp_seq=6 ttl=64 time=0.042 ms ^C --- 192.168.40.4 ping statistics --- 6 packets transmitted, 6 received, 0% packet loss, time 5104ms rtt min/avg/max/mdev = 0.026/0.039/0.058/0.011 ms(We set the IP address this way long ago and I've been using it successfully
until recently.) But uhd_usrp_probe returns: cmspooner>uhd_usrp_probe --args="addr=192.168.40.4" [INFO] [UHD] linux; GNU C++ version 11.2.0; Boost_107400; UHD_4.1.0.5-3 Error: LookupError: KeyError: No devices found for -----> Device Address: addr: 192.168.40.4 and uhd_find_devices gives: cmspooner>uhd_find_devices [INFO] [UHD] linux; GNU C++ version 11.2.0; Boost_107400; UHD_4.1.0.5-3 No UHD Devices Found I attempted to reflash the FPGA: cmspooner>uhd_image_loader --args="type=x300,addr=192.168.40.4" [INFO] [UHD] linux; GNU C++ version 11.2.0; Boost_107400; UHD_4.1.0.5-3 No applicable UHD devices found I'm probably missing something simple.
