[Discuss-gnuradio] Tunnel.py with USRP x310

[Danilo De Donno]

Dear all,

for several days, I made attempts to run the GNUradio ofdm/tunnel.py example, without any success. I have GNUradio 3.7.10 installed on a Desktop PC connected to a USRP x310. Whenever I try to run the tunnel.py example and use ifconfig to set my IP address, I receive the following output on the terminal where tunnel.py was launched:

 

UHD Error:

    x300 fw communication failure #1

    EnvironmentError: IOError: x300 fw poke32 - reply timed out

Tx: len(payload) =   90

Tx: len(payload) =   70

Tx: len(payload) =   90

Tx: len(payload) =  110

Tx: len(payload) =  107

Tx: len(payload) =  190

Tx: len(payload) =  351

Tx: len(payload) =  207

 

UHD Error:

    x300 fw communication failure #2

    EnvironmentError: IOError: x300 fw poke32 - reply timed out

Tx: len(payload) =  107

Tx: len(payload) =  190

Tx: len(payload) =   87

Tx: len(payload) =  269

 

UHD Error:

    x300 fw communication failure #3

    EnvironmentError: IOError: x300 fw poke32 - reply timed out

 

UHD Error:

    An unexpected exception was caught in a task loop.

    The task loop will now exit, things may not work.

    EnvironmentError: IOError: x300 fw communication failure #3

    EnvironmentError: IOError: x300 fw poke32 - reply timed out

Tx: len(payload) =  333

 

 

Then, the system hangs at this point and I’m not able to stop the execution, even with CTRL-C. I have to force CTRL-Z with consequent PC restart. Could you help me to figure out what is going wrong? Could you provide me with a working script or a solution to this problem?

 

Thanks a lot in advance for your help.

 

Best,

Danilo
