You probably had a mismatch between UHD version on the host (PC) and the FPGA firmware version on the USRP X310. See the procedure in the following links to update the FPGA firmware: https://files.ettus.com/manual/page_usrp_x3x0.html#x3x0_load_fpga_imgs https://files.ettus.com/manual/page_usrp_x3x0.html#x3x0_flash > I tried everything, but it wasn't solved, so I reinstalled Ubuntu, UHD and > GNU Radio. > But then when I connected the USRP to the computer through ethernet, the > computer didn't "see it".

You probably lost your network configuration when reinstalling your OS. The host NIC needs to be in the same subnetwork as the USRP to communicate with it. You will find information on setting up your network in the followings: https://files.ettus.com/manual/page_usrp_x3x0.html#x3x0_setup_network https://files.ettus.com/manual/page_usrp_x3x0_config.html#x3x0cfg_hostpc_netcfg Kind regards -- Cédric Hannotier _______________________________________________ USRP-users mailing list -- usrp-users@lists.ettus.com To unsubscribe send an email to usrp-users-le...@lists.ettus.com
