Hi,After a lot of testing/debugging (previously in thread "Firmware / FPGA
bitstream for USRP2 Rev 4") by using a re-compiled version of txrx.bin from
the gnuradio firmware source code, I was able to find out where the firmware
gets stuck:
Regardless of whether the usrp2 is connected to a machine
So, I finally got everything to work. It appears most of the problem
was due to me changing a who bunch of stuff at the same time. However,
by changing just the function name and then the module name
incrementally, I was able to rename howto_* as a new module with
different functionality.
Hello,
I need some help with an error I'm getting.
python: /usr/include/boost/shared_ptr.hpp:419: T* boost::shared_ptr<
>::operator->() const [with T = db_base]: Assertion
`px != 0' failed.
What could be causing this? The entire code is the following:
#!/usr/bin/env python
Hi Eric,
Great, thanks for your time with this! Can you e-mail me the most recent
version of your compiled RBF?
I have a full TDMA MAC that we can test this with. If the timestamps are
correct, we should be able to monitor the spectrum in the time domain and
see some very tightly spaced packet

Hi George, no worries, I know perfectly well how it is to have too many
ambitions and too little time... :-)
I can confirm that the timestamps are correct. I have been using it for
some time.
The compiled RBF is not in my developer branch. I haven't even moved my
recent work to git... :-/

Thanks a lot for the answer, Jonathan.
Yes, I am using 3.2.2, I'll try with the latest trunk, although I
remember that in past I had problems with building gr-pager on Ubuntu
9.10.
cheers,

p.s. I'm using 11370 firmware. Do I have to change the firmware too?

Hi All,
Is it possible to dynamically reconfigure a flow graph that has a usrp2 source?
I tested a simple lock()/unlock() from the top graph, and also from
the other parts of the graph. I always get the following error:

usrp2::rx_samples() failed

Hi Eric,
Sorry for the late response here, I've been wrapped up in so many things.
Is your latest compiled RBF in your developer branch? There are several
people I know (some that I CC'ed) that are interested in using the inband
code.
Last I checked, the timestamp had an issue of "jumping" whic
Just checking... :)
PS. the link works for me

I was wondering what the status was for the VRT work.
Are there any dates set or expected for being able to
use the USRP2 on Mac OSX?

Does anybody have information on what the receiver sensitivity or noise
