I think this might simply be a matter of out-of-boundary access on std::
vector. You don't set a size on your vector at creation, so it might have zero
elements, of which you try to set the first by doing k[0]. That means you
access memory that is not yet there, I.e. a segmentation fault. Try k.
Hello
I installed GNURadio in the Hummingboard which has debian jessie OS. But the
system cannot detect RTL-SDR. When I type command lsusb, it show Realtek
Semiconductor Corp. RTL2838 DVB-T.
when I type lsmod, nothing show up. And when I run gnuradio companion, no
signal show up in GUI interface
Hi everybody,
Some months ago we started working on an ISDB-T receiver for GNU Radio. We
have reached a point at which it may be useful for other people, so we
decided to announce to it on the list. The sources may be found on:
https://github.com/git-artes/gr-isdbt.
Although this is an ongoing wo
Hi all,
did anybody experience missing complete blocks panel in GRC? 3.6.5.1.
Thanx

Nicolas,
the tx_time tag is generated by the device, not by gr-uhd. So as a time
base, this should serve your purpose -- unless I misunderstood what
you're trying to do.

Hi all,
Right now I'm implementing tx and rx on the same device (USRP b210), and
I'm trying to synchronize the two in order to determine the exact moment
when a message is sent by the Tx. The purpose of this synchronization is to
add an idle state for tx right after the "sending state", so the Rx
Hi,
What is the proper way to set-up the multiplicative constant vector for
multiply_const_vcc?
I tried the code below and although it compiles, upon running the program I
get the following error:
*Segmentation fault (core dumped).*
The code:
std::vector k;
k[0]=0.1;

Hi Laur,
Thanks for your advice. I will try to test it.
Best regards,
