Hi
I built a custom RFNoC block. The simulation works as intended and the image
synthesizes. Unfortunately the block does not work when used in Gnu Radio.
I'm using a "Signal Source - DmaFIFO - Custom Block - Time Sink" for testing.
As soon as I press "execute" a bunch of errors appear.
[31;0m
I am seeing something weird that I am sure is a simple mistake on my side, but
I can't quite see what I am doing wrong.
I have a test transmitter outputting a signal at 391.5MHz. It is on 10s, and
then off 10s. This works fine and runs independently.
My flowgraph of interest on the receive
Hi there,
My name is Maria and I am contacting you as I have a really strange
problem when I try to use the tx and rx of my USRP X310 at the same time
to tx a simple CW signal at 3.5GHz and receive the same CW signal at the
rx (an attenuator is connected between the two ports).
The problem i

Ian,
I forgot to mention that I did test to see if the cable was at fault.
I swapped the cables and still only got a link on port 1. Using either
cable to either port on the NIC from port 0 on the radio results in no link
for several minutes. The light on the radio port immediately comes on
The gain settings were 0 for tx and rx and the attenuation was 10dB. I
increased the gain values but I still had the same problem.
Thanks!
Best regards,
Maria Jesus

Ian,
I take that back. I didn't realize the other X310 was on the HG
image. Once I updated it to the XG image port 0 stopped working properly.
No matter what combination of cable arrangements I use, port 0 just does
not want to come up even on the spare X310.
I don't have another syst

Hi everyone,
I was trying to transmit a signal from X310 for test,and an error

Stand down, I found the stupid mistake. I didn't realize that this X310 has
BX-120 daughter cards. So of course tuning to a freq that is WELL below the
operating freq range is going to give issues.
It would great with the USRP Source. When I switch to RFNoC radio, it would

Hi Everyone,
I am trying to transfer a text file from one Usrp B210 to another Usrp
B210.
I am able to see the frequency and time domain signal on transmission
side. But I am not able to receive any signal on the receiver side and also
no text information is received.
please see the below attac

Hello Brian,
Thank you very much for answering, I am spending a lot of time on this and
I do not see the way out.
I am following your advice, I have removed the 3 inputs of FPGA code, but I
am having problems.
I have doubts with:
- str_sink_tvalid and str_sink_tready[line 165]
- str_src_tready
Dave,
I might be miss-reading what you are telling me here but…..are you saying that
an “HG” image brought up both ports over a 10G Twinax passive cable to the
X710, but not the “XG” image? Is it possible either you or someone at Ettus has
got HG and XG switched in the latest release? Can you us
