Greetings,
I was wondering if anyone else has had this issue with the RFNoC radio
block.
So I was using the copy block with the rfnoc_fosphor_network_usrp.grc file
as I wanted to split off the signal before it went off to the RFNoC Window.
So I put in a copy block (since the RFNoC Split block
Greetings,
I was wondering if anyone is familiar with utilizing the FFT block from the
Ettus code library. I am using the default binary that is complied
following the instructions in [1]. I have a working environment and have
successfully used the foshpor window in the end example of that
Greetings Brian,
Thanks for the link. Yeah my Vivado always complains about the tcl cache
being unavailable unless I run as sudo. I think its b/c I installed it with
sudo, as otherwise it wouldn't make the /opt/Xilinx directory. It seems to
work either way regardless if it uses the official tcl
Greetings USRP Users,
I am having another issue with the UHD-3.14 build I can't seem to shake
down. I have been going through this guide on the KB to learn how to use
the rfnocmodtool to build new modules for my E312:

Unfortunately,
ed it up for me.

I am not seeing where this is declared in the CMakeList.txt file. Do you
know where I would go about changing it in the build scripts?

Greetings Brian,
I was having some issues with the build process, as the build script
couldn't find the gain.v block file even though I was pointing the script
to it. I saw that ejk github has some .inc files, so I added those and it
seemed to clear up the issue. *crosses fingers* The bit file
Greetings Brian,
Update: the noc_block_split_stream does work in the radio. However, it has
to be going to another hardware component first, like a FIFO, before it can
be passed to software blocks on the arm or the ZMQ to port to a host
machine. It was very interesting. I know in one of the

Greetings Nate,
So been working through your instructions you linked and everything appears
to be good on the software end. It is all cross-compiling and running on
the E312. Unfortunately there appears to be a new issue. So when running

Greetings,
I am having some issues completing the RFNOC build tutorial on the Ettus
E312. The reference documentation is using an X3xx series radio, and from
the final python script it appears to be running the GNR script natively on
the host. I built the exact script from the KB but when running
Greetings Nate,
Thanks for getting back to me so quickly. I will be sure to flash the OS to
release 4 and roll back my dev environment to match the instructions.
