[Discuss-gnuradio] Bug with USRP2/SBX and UHD when launching the acquisition
Hello all, I have a problem with my USRP2 (with a SBX board) : Most of times when I launch the acquisition, no data are received. For example with uhd_fft.py : $ uhd_fft.py linux; GNU C++ version 4.5.2; Boost_104200; UHD_003.002.001-fc349d3 -- Opening a USRP2/N-Series device... -- Current recv frame size: 1472 bytes -- Current send frame size: 1472 bytes and the FFT Plotter appear but is empty. I have to try up to five times to make it work. Anyone having the same problem ? Or do you know what may it be ? If it can help, I am using a Gigabit Switch and Ubuntu 11.04 -- Emmanuel ___ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org https://lists.gnu.org/mailman/listinfo/discuss-gnuradio
