Re: [Discuss-gnuradio] Mulitple USRP Stream Confusion

Hey Andrew, First, that subdev seems off -- I'd assume it's something like "A:0 B:0"? Next, I'm not even sure what you mean you set the channels to "0,1" on both devices. You should have 1 streamer, with a channel setting of "0,1,2,3". The 'args' string seems correct. Does this help? M On

[Discuss-gnuradio] Mulitple USRP Stream Confusion

2014-09-30 Thread Daigle, Andrew - 1008 - MITLL
Hello! I am having trouble trying to create a continuous stream of complex shorts from multiple (2) X310 USRPs (each running 2 channels) over a single 1gigE switch (at a very low sampling rate); currently it appears as though I can only stream from one USRP at a time and I can't seem to figure

Ok. I got it. Actually, I did run sudo apt-get autoremove but libvolk.so.0.0.0 was still there, so I tried removing it manually. Hoang Ngo-KhacResearch Assistant - Lab. of Signal and System, FET, UET, Vietnam National University-Hanoi (VNU-H)Alternative email: khachoang1...@gmail.com, hoangnk

Thank you all, I went into /usr/lib/i386-linux-gnu/ and remove libvolk.so.0.0.0 with root. Then I reinstalled gnuradio and it works now. Hoang Hoang Ngo-KhacResearch Assistant - Lab. of Signal and System, FET, UET, Vietnam National University-Hanoi (VNU-H)Alternative email: khachoang1...@gmai

libvolk.so.0.0.0 => /usr/lib/i386-linux-gnu/libvolk.so.0.0.0 (0xb749c000) That sounds like you installed gnuradio packages from your distro. Then possibly removed them, but not entirely, volk is still there. If you removed the GR packages already, try 'apt-get autoremove' Cheers, Sylvain
