[USRP-users] How to insert VHDL processing module to RFNoC block?

Hi community, I have some problems when trying to add VHDL processing module to RFNoC block. After inserted my VHDL module by the way described in addsub library module, I tried to run "*make rfnoc_block_Demodulation1_tb*" command and the output looks like the image below. [image: image.png] Do

[USRP-users] Generate blocks with more than 1 input/output using rfnocmodtool

Hi all, Is it possible to automatically create an rfnoc_block schema with, for example, 2 inputs and 2 outputs payload stream packets as in the addsub blockdata using rfnocmodtool? I can generate it using rfnoc_create_verilog.py through a block.yml file following the steps in : https://kb.ettus.co

[USRP-users] Building FPGA for E320.

Hi, I'm trying to build an FPGA for the E320. I'm new to Ettus products and RFNoC so this is my attempt. I'm working with UHD 4.0.0.0 and have been following the tutorial from the 2020 GNU radio conference, RFNoC 4 Workshop. I've used rfmodtool to create a new OOT folder structure. I've then u

[USRP-users] RFNoC/GNURadio with USRP-2974

Hi, We just received a USRP-2974 and would like to start working with RFNoC/GNURadio (rather than LabView).  I was hoping that somebody could direct me to a reference for configuring this SDR for RFNoC/GNURadio. There's a lot of material that covers non-embedded USRPs, but my understanding is

Re: [USRP-users] No streaming using OOT RFNoC Block in UHD4

Hi Cédric, I don't see anything wrong. Given that you said the FFT block works but your block doesn't, could it be something related to a c++ block controller? Attached is a program I use to test an individual block with the graph "host => block => host". It might help to see if this works. Thi

Re: [USRP-users] No streaming using OOT RFNoC Block in UHD4

By the way, I have created a block controller for every UHD4 RFNOC block that I have created and I simply compile them in-tree since I don't know how to make this work OOT. This has the nice advantage that uhd_usrp_probe can then know about my blocks. Rob On Wed, Jan 20, 2021 at 4:46 PM Rob Koss

[USRP-users] Overflow / Underflow Questions

We have an application that requires about 640Mbps of transmit and 640Mbps of receive samples bandwidth. We have a high performance Dell laptop hooked to a B205. Questions: 1. Do the different versions of UHD support different throughput rates? 2. Are there maximum sample rates for the B205 that

Re: [USRP-users] Generate blocks with more than 1 input/output using rfnocmodtool

HI Maria, Rfnocmodtool does not support multiple inputs / outputs. You'll need to edit the generated yaml file and use it with the utility rfnoc_create_verilog to generate the block and noc shell. See https://kb.ettus.com/RFNoC_4_Migration_Guide#Generating_a_Custom_Noc_Shell. To edit the yaml file
