Geof,
Thanks for the input. Here is what I get when running gnuradio_companion for
the bin directory after running run_gr.bat. I’m not a programmer so I don’t
know what all to look for. I used the application rapid environment editor to
see what my environment variables were. I don’t see a PYTHONPATH variable nor
do I see any entries in PATH related to GNURadio other than a path to the bin
directory which I added manually.
D:\Program Files\GNURadio-3.7\bin>gunradio_companion

Derek/Dave,
My development equipment is still in transit so I can't look at anything until
Monday, but...
The UHD build should be 64-bit, so it is mostly likely a labelling issue. But
I will check to be sure.
If you want to run -any- GNURadio utilities, I recommend doing so from the
GNURadio Command Prompt (shortcut in start menu or run_gr.bat in the /bin
subdir) ... that will set all the Python/etc environment variables up
correctly. Then you should not need to specify where the UHD images are.

Hi Dave,
Yes, there is no state held in UHD so you will always need to include the
--args "fw......" in your UHD commands. I should have also mentioned that this
means you will need to add that exact "fw= D:\Program
Files\GNURadio-3.7\share\uhd\images\usrp_b100_fw.ihx,fpga= D:\Program
Files\GNURadio-3.7\share\uhd\images\usrp_b100_fpga.bin" string in the USRP
Source or Sink block Device Arguments field for any GNU Radio flowgraph. You
can try modifying the wbfm example for instance.
The ability to specify specific FPGA and firmware images is usually a
development feature if you have multiple versions of UHD installed alongside
each other or are building custom images. In this case we are using it to get
around a path problem.
If you create the D:\Program Files\UHD\share\uhd\images\... folder with images
UHD will hopefully pick them up automatically. I have not tried a Windows
install where D is the system drive so I'm unsure of the exact behavior.
Ok, I had the wrong python command there, but python itself did run. Here's a
line which certainly should work, but there's likely nothing additional to be
gained by running it.
python -c "import gnuradio; print gnuradio"

Derek

I ran rx_samles _to_file. Although using the location arrguments you gave me
for uhd_find_devices allows for the B100 to be found it does not look like the
knowledge of where the images are located is retained. Running the
samles_to_file command again results in a condition where firmware could not
be found.

Hi Dave,
I'm glad that the B100 was able to be detected. If you want to confirm that it
is fully operating you could run any of the examples included with UHD, for
instance uhd_benchmark_rate or rx_samples_to_file. These are standalone from
GNU Radio so should avoid whatever Python issue may exist.
I've just noticed, the UHD version installed is Win32. I'm surprised at this as
the GNU Radio binary builds are all 64 bit. If the developer of these Windows
binary installers sees the thread hopefully he can comment.
GNU Radio is certainly easier to use on Linux or OS X, but there is a desire to
see Windows support improve over time. This may not happen quickly, but it's a
great sign that binary installers exist at all and I believe that most if not
all of the changes which were needed to make that possible are now in the
latest releases.
The binary installer at the moment includes it's own Python install in order to
minimize external dependencies and possible conflicts. I haven't seen the
"Stopped working" error before, it would be interesting to find out why. If you
have the time and curiosity, could you try running a super simple flow graph
such as a signal source into a null sink? This will have minimal complexity and
test if GNU Radio runs on it's own without any hardware interactions. The
gr_fftw_wisdom warning can be ignored.
Can you test the Python install? Here is a very simple command which should
execute. I'm on Linux so cannot test it at the moment.
python.exe -c "from gruel import pmt; print pmt"

Derek

Derek,
More success and a new problem. I used the example uhd_find_devices arguments
you show below modified for my system and the device was correctly found. Note
the windows installer does not create a UHD folder in the Program Files folder
but rather in the GnuRadio-3.7\share folder.
After finding the device I tested it using the uhd_wbfm_receive example and got
and error “python.exe has stopped working”. Below is the transcript. I guess
at this point, I’m not looking for solutions. I’m guessing windows installs
are just not prime time yet and if we solve this next problem another will
install issues will take its place. However, I will keep reporting problems if
it means something to the developers. Thank you very much for your help!

Hi Dave,
That's great news. This means the B100 is being found.
The images downloader is a Python script. Do you have a D:\Program Files\UHD
folder? Can you look there to see if the uhd_images_downloader.py script is
installed?
If, and I believe this is the case, the GNU Radio binary installer you are
using has the release version of UHD 3.9.3 then you can manually download the
images here:
http://files.ettus.com/binaries/images/uhd-images_003.009.003-release.zip
I'm not sure the exact folder they should be unzipped into for the UHD library
to find them given the custom build (UHD isn't usually in the GNU Radio bin
folder). However you can download the files, extract them somewhere (into
D:\Program Files\UHD\share\uhd\images if the UHD folder already exists) and try
manually specifying the fw and fpga paths.
For example but modify as needed:
uhd_find_devices --args "fw= D:\Program
Files\UHD\share\uhd\images\usrp_b100_fw.ihx,fpga= D:\Program
Files\UHD\share\uhd\images\usrp_b100_fpga.bin"

Thanks Derek,
I tried using Admin privileges and that did not make a difference. I believe
all the ports on my machine are USB3 however I’m not sure they use exactly the
same hardware. In any event I tried another one and it did make a difference.
I now get the message below regarding the need to run uhd_images_downloader. I
ran it (also below) and it indicates it needs me to specify a device however I
have not figured out the correct way to do that. Note: All the images appear
to be already on the machine in the share/uhd/images directory. Also as you
see below the message states to run
C:\ProgramFiles\UHD\lib\utils\uhd_images_dowloader.py. My installation is on
the D: drive not the C: drive and the downloader appears to be an .exe file in
the GNURadio-3.7\bin file. I don’t know if something is looking for code in
the wrong places or not.

Hello Dave,
Thanks for posting again. I don't know if anyone else has tried the B100 using
the Windows UHD+GNU Radio binaries. Are you connected to a USB 2 only port or
to a USB 3 port? I would try a dedicated USB 2 port if possible.
Also, I don't believe that permissions issues exist to the same degree on
Windows, but can you try running uhd_find_devices in an administrator prompt?
Regards,
Derek

I am trying to install GNURadio on a Windows 7, 64 bit machine for use with a
Ettus B100 usrp. I used the gnuradio_3.7.9.2_win64 installer referenced on
the GNURadio installation guide.
When I run uhd_find_devices I get the following:
D:\Program Files\GNURadio-3.7\bin>uhd_find_devices
Win32; Microsoft Visual C++ version 14.0; Boost_106000;
UHD_003.009.003-0-unknown
No UHD Devices Found
When I look in my device manager I do see a USRPs device show as “Ettus
Research LCC B100”
I posted this issue last week on the USRP discussion list and was advised to
make sure I had only one instance of UHD. I discovered I had incorrectly
installed gnuradio using the installer mentioned above and also installed UHD
using the installer on the ETTUS website not realizing the GNU radio installer
took care of both. I uninstalled GNU radio and uhd and removed everything I
could find for both. I then re-ran the gnuradio_3.7.9.2_win64 installer. I
still have exactly the same problem shown above with the inability to find the
device.
Note: I can successfully use gnuradio and the USRP device on this same
computer using the LiveUSB image thus I don’t believe there are any hardware
issues.
Can anyone provide me more tips on how to troubleshoot my installation?
Thanks,
Dave
