I am having great difficulty with basic communication to/from my newly purchased USRP N210. Any help greatly appreciated since this is rather frustrating - I had hoped to spent my time on debugging GNU RADIO py scripts at this time :( I have downloaded and built the latest GNU RADIO software. I have downloaded the latest UHD and done a build according to instructions. The first step was to do a ping : I experience the same problem as reported by others : checksum failure cause ping to fail Next step is to issue the command "uhd_find_devices". This results in the following: ---------------------------------------------------------------------------------------------------------------------- Linux; GNU C++ version 4.4.5; Boost_104200; UHD_002.20110202043814.fa35192 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. ----------------------------------------------------------------------------------------------------------------------- I tried to burn the firmware with the usrp_net_burner (./usrp_n2xx_net_burner.py --ip=192.168.10.2 --fw=/usr/share/uhd/images/usrp_n2xx_fw.bin). This results in : ----------------------------------------------------------------------------------------------------------------------- USRP2P found. Flash size:8388608 Sector size: 65536 Erasing 31744 bytes at 3145728 Writing image Verifying data Read back 16383 bytes Success. ---------------------------------------------------------------------------------------------------------------------- This looks ok, but then I try to burn the fpga image (./usrp_n2xx_net_burner.py --ip=192.168.10.2 --fpga=/usr/share/uhd/images/usrp_n210_fpga.bin). This results in: ---------------------------------------------------------------------------------------------------------------------- USRP2P found. Flash size: 8388608 Sector size 65536 Erasing 1572864 bytes at 1572864 timed out --------------------------------------------------------------------------------------------------------------------- What am I doing wrong here? Are there any further test, that I can carry out in order to pinpoint the cause(s) of the problem? Regards, John Rohde

Are you updating the firmware through a switch, or on a public network? Does the update always fail exactly at this point? If you type "ifconfig eth0" (or eth1... whichever card your N210 is connected to), does it show errors, dropped packets, frame errors, or overruns? When the updater says "Erasing 1572864 bytes at 1572864" but before it times out, is the orange Ethernet LED on the N210 solidly on? If you have another PC you can try the update from, that would be a very helpful data point as well.

Hi Nick, Thank you for the reply. Comments: 1. I am updating with supplied cable attached directly between PC and USRP N210. I have tried inserting a Gbit switch, but results are identical. 2. Update fails at exactly the same point every time I try this approach. 3. ifconfig eth0 -> zero errors, dropped, overruns and frame -> everything looks ok. 4. The orange LED is solidly "on" for some seconds and then turns off. Then, the time out occurs. 5. Another PC: I will try to get hold of another PC and test this, but unfortunately, I will have to start from scratch (installing Ubuntu and work my way forward from there...) Any ideas based on the info above?
