[USRP-users] Generating Packets in a 2-Port Block

Hi all, I am currently working on a RFNoC block that has a ‘passthrough’ port and ‘results’ port that outputs data based on the samples seen in the passthrough stream. I am currently using the AXI-stream payload context interface and I am having trouble deterministically generating packets

Rob, This did fix my problem and I can now generate deterministic packets! Thank you, Rylee Mattingly University of Oklahoma Graduate Research Assistant From: Rob Kossler Date: Tuesday, March 30, 2021 at 4:02 PM To: Mattingly, Rylee Cc: usrp-users@lists.ettus.com Subject: Re: [USRP-users

[USRP-users] Verilog Module Directory

Hi all, I have broken the code for my RFNoC block into a couple of different Verilog modules to help with single file complexity. Unfortunately, when I try to build the image it doesn’t find the module files when I put them in fpga/ directory of the OOT tree module. I have also tried one of the

[USRP-users] Re: Can any guide me in rfnoc blocks?

My understanding is that the NoC shell, instantiated inside the RFNoC block, takes in the raw CHDR bus for the control and data planes and provides a more user friendly data interface for your user logic to interface with. The NoC shell is autogenerated by RFNoC Modtool and shouldn’t need any e

[USRP-users] rfnoc_chdr Clock on X3xx Radios

Hello all, I am looking at the RFNoC FAQ page and it lists the rfnoc_chdr clock as 187.5 MHz. Now this is plenty fast to pipe around packets and sequential headers for the 184.32 MS/s sample rate but how does this support the 200 MHz maste

[USRP-users] Re: rfnoc_chdr Clock on X3xx Radios

to operate at 200 MS/s expect a NIPC of 2 from the upstream blocks. Does the streamers understand if it is expecting 2 samples per clock or 1 sample per clock? Rylee From: Wade Fife Date: Friday, July 1, 2022 at 9:19 AM To: Mattingly, Rylee Cc: USRP-users@lists.ettus.com Subject: Re: [USRP

[USRP-users] RFNoC OOT Module w/ GNURadio 3.10.5

Is there currently a way to create custom OOT RFNoC blocks that work with GNURadio 3.10? I am currently using UHD 4.4.0.0 and GNURadio 3.10.5.1 and I am looking for an alternative to build RFNoC blocks that function with GNURadio. I have been using gr-ettus to build OOT blocks for GNURadio 3.8

[USRP-users] RFNoC 4 FFT with GNURadio

Hi all, I am trying (and failing) to get an RFNoC image with the provided FFT working with GNURadio. I am using an X310 connected with a 1Gig ethernet and building images in the HG configuration. I used the knowledge base article: "Getting Started with RFNoC in UHD 4.0" (linked here: https://kb

[USRP-users] RFNoC FFT >512 Samples

Hi all, I am having trouble with the RFNoC FFT. When using an FFT length of 256 or less everything works smoothly but when I use a 512 or 1024 length FFT I begin to receive a flood of repeating packet errors like: ERROR_CODE_BAD_PACKET (Code: 0xf). I haven't been able to find any information o
