Hello,
Thank you for your answers. Actually, we need to achieve this task.
This task should be performed in B210 (I guess, ethernet MAC is drived
by FPGA in here). So, how can i start to this task ? Where can i find an
example or some information to drive built-in ethernet MAC in FPGA ? It

Hello,
We want to use E310 as a peripheral network device like N210. We want
the RF samples come to ethernet interface through FPGA without passing
from CPU. In short, we don't want to use CPU. So, can we configure FPGA
to achieve this task? (Connecting ethernet interface directly to FPGA)

Hello,
I am trying to make OFDM transmitter on E310. In attached flowgraph
there are lots of gnuradio blocks for OFDM TX. I want to put FFT block
into FPGA to reduce computation load on CPU.
But data is passed with tags like tagged stream, so when i used RFNoC:
FFT block instead of gnuradio
was designed to be a standalone embedded SDR, not a networked
device with full BW streaming capabilities.

Hello,
We want to run USRP E310 in network mode. I think the samples coming
from FPGA passing through CPU before sending to network. This decreases
bandwidth because of CPU limitations.
So, is there any ettus image or suggestions that we can run E310
directly from FPGA to network without sp

Hello,
I am trying to build basic OOT module for N310. My UHD version is
3.14.0.0-rc1 (I also tried with 3.14.0.0). I can build FPGA image
without OOT modules for N310. But when i try building with OOT module
using this command, it gives this error:

Hi again,
I could resolve this issue by restarting hwdaemon;
systemctl restart usrp-hwd.service
This solves problem. After that i need to load the FPGA image again.
Best regards.

I am using N310 for my gnuradio OFDM application. Sometimes, my gnuradio

Thanks you for your suggestions. I have achieved getting 60 MHz spectrum

Thank you for your reply. I just tried what you said and investigated
gr-ettus/examples/rfnoc/rfnoc_vector_iir.grc. I firstly tried without
using keep 1 in N block. I just sampled 2MHz and try to get FM radio
samples of spectrum. My flowgraph is attached.
