You may have a version mismatch between the installed python modules in
lib and installed python scripts in bin. Either that, or its a very old
bug. Whatever the case, I recommend you nuke your gr install(s) and grab
a recent release.
First of all bundle of thanks. Last post did help me alot.
I installed a fresh gnruadio 3.4.0. Connected the USRP1 and usrp_probe
ran
successfully.
Both the boards were detected.
When I tried to connect DBSRX2 to RXB or RXA the it wasnât detected. I
mean
when I ran usrp_probe the model shown was âunkownâ and frequency range
was
from -9000000.0 to 9.000000. Any help what I need to do in order to
check
the DBSRX2 ?
Also I got N210. How can I test it. Please help.
Waiting for a quick response as I am worried. Any help in this regards
is highly appreciated.
If you want to test signal integrity, configure gnuradio with gr-uhd
support. There is a very basic signal generator and analyzer display
that comes with the component. uhd_siggen_gui.py uhd_fft.py I believe.
Or make a quick flowgraph in gnuradio-companion
I downloaded UHD from link above, then I did following.
cd UHD.
cd host
mkdir build
cd build
cmake âŚ/
make
make install
ldconfig
But then when I ran uhd_find_devices I got following output:
âIgnoring discovered device RuntimeError: Expected protocol
compatibility
number 9, but got 7: The firware build is not compatible with the host
code
build.
No UHD Devices Foundâ
Lights D and F are on the N210. No other lights.
Another question what is minimum speed required for LAN(Etherenet)
interface on PC ? 100Mbps or 1000Mbps ?

You can install in userspace but then you need to be sure PYTHONPATH
and maybe LD_LIBRARY_PATH are pointing to your install. Most users
do âsudo make installâ to install in /usr/local.
ldconfig will not find things in userspace and elf-ld canât figure out
that a program in /something/bin might have libraries in /something/lib.
After you do cmake, the Makefile should be able to clean out old
stuff with âmake uninstallâ and âmake cleanâ before the new make and
sudo make install.

DBSRX2 is only supported under UHD, not under the âclassicâ drivers. If
you run:
uhd_usrp_probe --args âtype=usrp1â
Youâll find that it can cope with the DBSRX2 just fine. Since youâre a
new user of this gear, without any
necessity of backwards compatibility with older software, you should
be using UHD exclusively.

The ethernet-connected devices (USRP2, N2XX) require 1 GiGeâthey wonât
work at any other rate.
Follow the instructions here to update your N2XX firmware:
If you used the âbuild-gnuradioâ script to build your Gnu Radio + UHD
installation, it will also have downloaded
the very latest master firmware, and placed it in
/usr/local/share/uhd/images.
You might also look at the overall UHD documentation here:
Thanks for the response, I did sudo make and sudo make install when I
was
installing the UHD. My UHD folder is in my home directory. Sorry, I am
not
getting you with your last post because I am not very good at Linux. Any
help further is highly appreciated.

Smith
