You'll have to burn the appropriate image into the USRP2 for it to support UHD. The UHD "wire protocol" has undergone several revisions in the last year as well, so it's good to have your USRP2 firmware match the host-side software. Further, the stock USRP2 firmware doesn't have an IP stack at all--it used so-called "raw ethernet" frames for communications, so it's not able to respond to pings, which use the ICMP ECHO (part of IP) protocol.
You'll find that the build-gnuradio script will have installed firmware images in: /usr/local/share/uhd/images And you can use /usr/local/share/uhd/utils/usrp2_card_burner_gui.py to place new firmware and FPGA images onto your USRP2 SD card. -- Principal Investigator Shirleys Bay Radio Astronomy Consortium http://www.sbrac.org _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org https://lists.gnu.org/mailman/listinfo/discuss-gnuradio
