I read almost everything on the forum regarding this problem and tried my best.I am providing as much details as possible hence the post became long.I hope it will help the forum to help.
I am working with USRP2.I installed GnuRadio as well as UHD(Using Marcus D. Leech script).I changed the host computer IPV4 address to 192.168.10.1 with subnet mask 255.255.255.0.Disabled the firewall also. Now… 1.When I run usrp2_probe.py its returning the device Mac address : 00:50:c2:85:42 Name(ID): -1 Converter Rate,gain Range,Freq Range. 2.When I run uhd_find_devices.py It returns linux; GNU C++ version 4.4.3; Boost_104000; UHD_003.001.002-a3e1cb7 No UHD Devices found. 3.When I do ping 192.168.10.2 Its says “destination host unreachable” 4.I also then tried to change the default IPV4 address of USRP2 by sudo ./usrp2_recovery.py - -ifc=eth0 - -new-ip=192.168.10.3 Then I pinged but same “destination host unreachable” 5. Then I monitored the network traffic on wireshark.I found….. a.When I do usrp2_probe.py then there happens communication between host and USRP2 and the USRP2 sends back his mac address to the host(was clearily visible in the wireshark). b. But when I do uhd_find_devices.py then the host broadcasts message but there is no reply packet from usrp2 at all. 6.Then I scanned the network using nmap but was not able to find any device there with IPV4 address 192.168.10.3(modified one) up.Then I also searched for 192.168.10.2 but no help at all. 7. When I boot he USRP2 then all LED’s blinks as given in the youtube video i.e. all blink in the beginning and finally only D and F remains glowing.Also the green light to the left of the Ethernet cable keeps glowing.The orange light to the right keeps blinking now and then when I do nmap scanning. 8.My host computers have gigabit Ethernet ports so that is not an issue I think. 9.I burnt my SD card with the firmware FPGA image as given at http://code.ettus.com/redmine/ettus/projects/public/wiki/U2binaries Raw Ethernet rel-20100603 d488c6b2 June 3, 2010 5b73d3a67d7998d83936906dac0cb200 Raw Ethernet, with XCVR2450 v3.3.1git Jun 08, 2010 Use this with Raw Ethernet and the XCVR2450 I also checked the MD5 sum to make sure that I got the proper bin files. I have 3 USRP2 devices and the same problem prevails in all the three. No communication is happening above the layer three. Let me know what more I should try. ----- Sumit Kr.
