Help: UHD, gnuradio and USRP

dubstep · July 7, 2011, 3:34pm

Dear all
i have a usrp and i have installed the uhd and gnuradio 3.2
when i use sudo uhd_usrp_probe in the terminal i have this output:

ziedan@ubuntu:~/Desktop$ sudo uhd_usrp_probe
linux; GNU C++ version 4.4.3; Boost_104000; UHD_003.001.002-a3e1cb7

– Loading firmware image: /usr/local/share/uhd/images/usrp1_fw.ihx…
done
– Opening a USRP1 device…
– Loading FPGA image: /usr/local/share/uhd/images/usrp1_fpga.rbf…
done

and when i am running any python script i have this error:

Warning: Treating daughterboard with invalid EEPROM contents as if it
were a
“Basic Rx.”
Warning: This is almost certainly wrong… Use appropriate
burn-*-eeprom
utility.

Using RX d’board A: Unknown (0x0053)

so what is the solution ??
thanks a lot

gnuradio 3.2 does not have the UHD blockset, you need to install
gnuradio from source to use UHD:

It looks like you have UHD installed successfully already

and when i am running any python script i have this error:

“Basic Rx.”

This error is because the python script you ran is trying to access
the usrp + WBX with libusrp1 from gnuradio 3.2, which does not support
WBX.

The solution is to use programs that understand the UHD API, or to
convert the programs that you’re interested in to use UHD.

What happens if you use a simple “uhd_fft.py” on your system?

And I just noticed that you mentioned Gnu Radio 3.2. I was assuming that you’d
installed from recent source. You’ll need the very
latest Gnu Radio. If you don’t mind starting over from the beginning, you can
download the following script:

http://www.sbrac.org/files/build-gnuradio

Which will take care of building everything, installing, and making certain that
you have the pre-requisites. It will also uninstall anything
you’ve installed as a packaged binary, so that there won’t be any conflicts.

Hi Marcus,

I have got some problem with my GNURadio+UHD installation. I have seen
you mentioned this script for installation
several times, I am curious about how to use this script to easily
install GNU Radio+UHD?

Really appreciate your help!

Thanks,
Yan

I haven’t tried an F15 setup yet, but make sure your PYTHONPATH is
correct–keep in mind that on 64-bit systems,
Fedora likes to use /usr/local/lib64 rather than /usr/local/lib

Hello Marcus,

I have just done an install using your script and it worked fine in that
it all the required software seemed to be installed and the build seemed
to run & complete OK for both UHD & GNU Radio.

I tried running gr-uhd/uhd_fft.py and got an error:

[root@LinuxPC apps]# python uhd_fft.py
Traceback (most recent call last):
File “uhd_fft.py”, line 23, in
from gnuradio import gr, gru
ImportError: No module named gnuradio

This looks a bit fundamental, have I missed out on something, not set up
a path perhaps?

It’s a Fedora 15 setup. PYTHONPATH is set as in the build instructions.
One of my colleagues has run usrp2_fft.py successfully with the earlier
drivers on a USRP2 platform some time ago, so should the gr-uhd version
work OK the latest build?

Regards
Ian.

Update: GRC works fine; the command name has been updated to
‘gnuradio-companion’ NOT ‘grc’!

My only question remaining for now is what’s wrong with that
‘uhd_fft.py’ command. I don’t know much about python yet, so I’m having
trouble reading the error output.

eng_z · July 10, 2011, 3:17am

Hello all,

I have installed using the build script by Marcus and am trying to get
GRC to run, but it is apparently not in my path. I tried adding it from
a package on my second system, but that resulted in various errors (and
now I realize from this thread that it should be already included by the
script). What is the location so I can check the path? I installed on
Ubuntu 11.04

Meanwhile, I’m checking the rest of the install. I have successfully
run the dial tone application (phone tones) here:

http://www.joshknows.com/gnuradio#example

I am able to run the probe command with the following output:
