Hi,
I’m a newbie. I received my hardware and trying test it.
I started to test the USRP2 (last release of firmware) and FLEX900 with
the
“usrp2_fft.py”.
My system is Ubuntu 8.10 and the trunk version of gnuradio.
I’m trying this command:
#sudo usrp2_fft.py -f900M
But the graphic window of “USRP2 FFT” freezes and not responds anymore,
so I
need to kill the application. The spectrun don’t show any communication
at
900Mhz, even with many radios working in this frequency.
If I try run again (sudo usrp2_fft.py -f900M) the following error
occurs:
"RuntimeError: Unable to retrieve daughterboard info"
So I need turn off and turn on the USRP2 to stop the error and run the
“usrp2_fft.py -f900M” again.
What am I doing wrong?
Thank you!

Can you confirm the version of the USRP2 FPGA code and firmware that
is written to the SD card, as well as the revision number of the
“latest trunk” that you have installed on your system?

No any response? Maybe the host pc loading is too heavy.
What is the horsepower of CPU?

Maybe it is still running.

I am having a similar problem. I used ethtool to disable the pause
parameters for this interface; here is the output:
sudo ethtool -a eth1
Pause parameters for eth1:
Autonegotiate: off
RX: off
TX: off
But I still get this error when i run tx_samples:
sudo ./tx_samples -e eth1
terminate called after throwing an instance of ‘std::runtime_error’
what(): Unable to retrieve daughterboard info
Creating USRP2 Object… Aborted
I’m running the latest version of GNU Radio (freshly re-complied this
morning, revision 10644) on Ubuntu 8.10. I have a USRP2 with the
firmware
and bit file that was complied on March 15th 2009 and the xcvr2450
daughterboard.
Are there any other ideas as to what could cause this (or did I disable
flow
control pause wrong)? Thanks!

Please see this message from yesterday:

Try the new firmware without forcing anything with ethtool. (Leave
autonegotiation enabled.) It should come up with a sensible answer.
On my system I get:
[eb@octo trunk]$ ethtool -a eth1
Pause parameters for eth1:
Autonegotiate: on
RX: on
TX: off
Which is what I expect.
