Hi, First, thank you for yours answers. I did not see that point and so I re-install gnuradio and uhd as showed in the link you gave me using the git. Everything went good but when I run uhd_find_devices, I have this message :
#gnuradio@gnuradio-Precision-WorkStation-340:~$ uhd_find_devices #linux; GNU C++ version 4.4.5; Boost_104200; UHD_002.20110206225409.aea6ac1 #Warning: # Ignoring discovered device # Expected protocol compatibility number 8, but got 7: # The firmware build is not compatible with the host code build. #No UHD Devices Found Do I have to update directly the firmware installed on the USRP ? or it is just a problem on the computer ?
