Dear Wade,
Thank you very much for your response. The YAML was modified by ettus research
(Jonathon). He added replay block and sent me via email. I replaced that file
in following folder (uhd/fpga/usrp3/top/e31x) and then run command. I also
installed vivado 2021.1 according to his instruction
Could you please tell me how can solve this issue? As I am using GNU radio,
when I increase sample rate beyond 2MS/s it misses samples. So, Ettus suggested
me to use RFNoC replay Block. They also provided me with YAML file. I have two
E313 USRPs and I have to use them for outdoor channel modelli
Hi Wade & Rob,
Thank you for your help.
I am a new user, so I do not know much about Linux and FPGA. My aim is to use
my usrp with high sampling rate so I was recommended to use RFNoC replay block.
For this purpose, I received YML file from Ettus (from Jonathon). I replaced
that file (e310_rfn
Hi All,
I am trying to run this command “uhd_image_loader --args
type=e3xx,adr=192.168.10.2
--fpga-path=/home/grcusrp/uhd/fpga/usrp3/top/e31x/build-E310_SG3/e31x.bit”
But I get error which is “Error: RuntimeError: Failure to create rfnoc_graph”.
the whole output is “\[INFO\] \[UHD\] linux; GN
Dear Rob,
Sorry for the wrong command. I executed following command “uhd_image_loader
--args type=e3xx,adr=192.168.10.2
--fpga-path=/home/grcusrp/uhd/fpga/usrp3/top/e31x/build/usrp_e310_sg3_fpga.bit”.
Please also find the attached YML file.

Dear Rob,
I have following bit files generated at the same time.
1. named “usrp_e310_sg3_fpga.bit”. this file is in build folder
2. named “e31x.bit”. which is in “build-E310_SG3”
build-E310_SG3 folder and build folder, both are in e31x folder.
I tried to run both these files and get same error
Dear Rob,
You are right, when I try to run this command “rfnoc_image_builder -y
./e310_rfnoc_image_core.yml”, **it fails**. **I also tried to use your given
YML file**, it was not successful because of the different UHD version. The
only command which worked for me is “rfnoc_image_builder -y
these are the further results. In which now I can see that there is replay
block after executing uhd_usrp_probe. I am really thankful to your help.
