Hi Ian,
USRP specific questions (especially FPGA/Hardware) are best directed
at the USRP mailing list, rather than the GNURadio one.
You are right in your suggestion :)
It's hard to say exactly what has caused this error, but basically it;s
failing to identify the module name that is the
usrp_n200_fpga_r3.bin file. Right?
Thanks,
Mahboob

All,
I am trying to modify the USRP N200 FPGA so as to mute the ADC when TX section
is enabled inside my flow graph. However, when I try to build the
usrp_n200_r3_fpga.bin file, I get below error message which I don't understand:
l-ece109:N2x0$ make -f Makefile.N200R3 bin

Hi Josh,
So it would be possible to mute the ADC samples when the device is
transmitting. However, that might only be desirable in a couple of use
cases, and there are probably a dozen ways to solve this from all the
way down at the physical layer up the the MAC layer:
* mute the RX ADC when
Hi Marcus,
I assume you are talking about the green LED on the top left of Ethernet port
on USRP N200. If so, then it remains On. However, I don't see any yellow
activity light at all. Furthermore, only LED D and F are On.
Thanks,
Mahboob

You might want to try using usrp2_recovery.py you'll have to run it as root,
and it will attempt to restore to the default address.
I suspect that your device
All,
When I connect my USRP N200 to a PC running Suse, run ifconfig eth0

--args=addr=192.168.10.2, I see the famous error message:

Hi Tom All,
I am now doing consume_each(noutput_items) but my problem is not solved yet. I
have also made sure that my code effectively sends one sob tag and one eob tag
per burst of samples.
Questions about new experiment:
Now, I have created yet another simple experiment whose flow-graph is
All,
I have made a simple custom block (derived from gr_block class) whose
general_work() function is given below:
int howto_my_custom_blk::general_work (int noutput_items, gr_vector_int
ninput_items, gr_vector_const_void_star input_items, gr_vector_void_star
output_items){

Hi all,
I want to make a simple hard limiter block (hlimit_ff()) which works as follows:
if input0
output=-1
else if input0
output=1
else
output=0
So, in essence, I have downloaded the tar ball
gr-how-to-write-a-block-3.2.tar.gz and replaced 'square' with 'hlimit' in the
howto_square_ff.h,

Hey,
You can't make a feedback system in the Python flowgraph. You can, however use
feedback in an individual signal processing block
Hi,
I am trying to send, then receive and finally display a sinusoid of arbitrary
frequency say 128KHz using two usrp's and two computers. I have used grc on
both computers to do so.
On tx computer, the flow graph of grc is:
signal source -- usrp sink
In signal source, I set the frequency of
