As I mentioned in previous email (below), the first thing you need to do now is to bring up the physical layer of the Ethernet connection.
If the GE port LED is not ON, no point to proceed without this being solved first.

If you insist that your hardware support 1000Mbps GE, then make the Linux recognise this first before troubleshooting at the gnuradio level.

Now you should troubleshoot your Linux, not gnuradio, if you confirmed that your hardware is really GE capable.

You shall troubleshoot in the following steps:

1). Bring up the physical ethernet connection between your PC and the USRP. Upon successful you will see the LED turns on at the USRP GE port.

2). Set your PC IP address to the same subnet but don't crash with the USRP's ip address.
If this step is successful then you will be able to ping the USRP.

3). Issue command "uhd_find_devices" and you will see the USRP being discovered.

Then you could proceed with "uhd_usrp_probe" to see more details.

i'm seeing only LED's D and F are on, because host pc is not at all detecting the hardware and i'm unable to run any operation.In my first i mentioned the errors what i'am getting when i run the flowgraph.
Even i'am clueless how my device is only showing up 10/100Mbps when i connect the hardware and even i tried with other pc but i'm facing the same problem.

Thanks and regards

If that is a new USRP from factory then you don't need to update the firmware.

Thanks for the reply.
Well is that only problem so that i'm unable to communicate and should i need to update the firmware?

Your pc must have 1000Mbps port. The 10/100Mbps won't work.
An alternative is to connect a 10/100/1000 LAN switch between your pc and the USRP.

HI all,

I have followed as per the instructions given in the webpage for set up of the Usrp N200/N210 but still i am unable to communicate between the hardware and host pc

                1.I have set the static ip of the host pc to 192.168.10.1(ifconfig eth0 192.168.10.1).

2.Whenever i give the device address=addr=192.168.10.1 and run the grc i am getting the error has “unknown key format”

3.Whenever i ping 192.168.10.2 or use the command uhb_find_device i am getting warning as “NO DEVICE FOUND “

4. Is that a must i have to upload the fpga and firmware images when using the device for the first time.

5.Sometimes i am getting an error like” unable to find as single device”.

6.The host pc is supporting only 10/100MBPS .Is that the only problem so that i am unable to communicate with the hardware.

Can anybody help me on this issue.Awaiting for your valuable reply

Thanks in advance

Sandhya.G
