Subject: [USRP-users] uhd::assertion_error at memory location
0x0037ecfc
Message-ID: <[email protected]>
Content-Type: text/plain; charset="us-ascii"
Hey everyone,
I wrote a very simple program using MSVC 2010. Here it is:
#include <uhd/utils/safe_main.hpp>
#include <uhd/usrp/multi_usrp.hpp>
#include <uhd/device.hpp>
#include <boost/format.hpp>
#include <iostream>
#include <cstdlib>
int UHD_SAFE_MAIN(int argc, char *argv[]){
uhd::usrp::multi_usrp::sptr usrp;
std::string param;
uhd::device_addr_t adder = ("addr0=192.168.10.2");
usrp = uhd::usrp::multi_usrp::make(adder);
param = usrp->get_pp_string();
return EXIT_SUCCESS;
}
I included the files from boost, and the files from uhd(from github):
Using:
C:\Users\iftah\Documents\GitHub\uhd\host\include
C:\Users\iftah\Downloads\boost\boost_1_55_0
And I add the files from boost\lib and uhd\lib:
C:\Users\iftah\Documents\GitHub\uhd\host\lib
C:\Users\iftah\Downloads\boost\boost_1_55_0\stage\lib
+ I add to the project the file uhd.lib from:
C:\Program Files (x86)\UHD\lib
The project pass build with this output:
1>------ Build started: Project: new_uhd_test, Configuration: Debug Win32
------
1> new_uhd_test.cpp
1>new_uhd_test.obj : warning LNK4075: ignoring '/EDITANDCONTINUE' due to
'/INCREMENTAL:NO' specification
1> new_uhd_test.vcxproj -> c:\users\iftah\documents\visual studio
2010\Projects\new_uhd_test\Debug\new_uhd_test.exe
========== Build: 1 succeeded, 0 failed, 0 up-to-date, 0 skipped ==========
And when I run it, it exit with error(copy only from where the problem
starts):
First-chance exception at 0x7540c41f in new_uhd_test.exe: Microsoft C++
exception: uhd::assertion_error at memory location 0x001bee1c..

The thread 'Win32 Thread' (0x184c) has exited with code 0 (0x0).
The program '[0xB24] new_uhd_test.exe: Native' has exited with code -1
(0xffffffff).
And on the cmd I get this error:
error: lookuperror: indexerror: multi_usrp::mb_root(1614943298) - invalid
vector <T> subscript
I think I tried about everything.
I even tried moving the project to release, and when I did that, the build
was o.k:
1>------ Build started: Project: new_uhd_test, Configuration: Release Win32
------
1> new_uhd_test.cpp
1> Generating code
1> Finished generating code
1> new_uhd_test.vcxproj -> c:\users\iftah\documents\visual studio
2010\Projects\new_uhd_test\Release\new_uhd_test.exe
========== Build: 1 succeeded, 0 failed, 0 up-to-date, 0 skipped ==========
But then when I run it, it crashes.
Unhandled exception at 0x0f9f55a6 in new_uhd_test.exe: 0xC0000005: Access
violation reading location 0x72646461.
Help, please.
Thanks,
iftah

Subject: [USRP-users] Install instructions/pre-reqs for GNU Radio on
Windows?
Message-ID: <[email protected]>
Content-Type: text/plain; charset="us-ascii"
I'm eagerly awaiting my B200 which shipped out Friday, and want to go ahead
and start to get my software installed, etc.. I'd like to use it on my
Windows 7 machine, with (among other programs) GNU Radio.
I've found the Ettus-built binaries here:
http://files.ettus.com/binaries/gnuradio/
But there's not much in the way of instructions for pre-reqs, etc. . I
found these:
http://code.ettus.com/redmine/ettus/projects/uhd/wiki/GNURadio_Windows
But, it talks about dependencies as of Jan 15, 2012. Is there an updated
list of prerequisites with newer version numbers?
Thanks!!!
Robert

Hi
Can we use CBX daughterboard for simultaneous transmission and reception?

Yes. You can work full duplex by TXing with the TX/RX port and RXing with
the RX2 port. Or you can work half-duplex with just the TX/RX port doing
both.
Very Respectfully,
Dan CaJacob

Thanks Marcus ? I hadn?t realised that overflows could be caused by the
consuming application as well. Will do some digging on this front!

Don't forget that benchmark_rate is simply testing the interface rates, without
*doing* anything to the resulting sample stream--just dropping it on the floor.
Your two quoted examples are passing said samples, somewhat circuitously, up
into application land, where said applications are performing
computationally-expensive
operations on those samples, at the same time updating UI components, etc,
etc. There's a *huge* difference in computaional and memory-bandwidth
footprint between
benchmark_rate, and any kind of "real" application.
