Re: [USRP-users] Trouble getting custom RFNoC block to work with gnuradio 3.8 / uhd 4.0

Hi Jim, I have also been playing around with UHD-4.0, but mostly in testbenches. I've only built one image (for the N310) with one of my custom blocks. The errors you mentioned seem very strange. A few questions/comments: - can you send your "XXX_x310_rfnoc_image_core.yml" contents? - would it be h

Hi Andrew, I'm definitely no expert on networking, but the one thing that caught my eye in the config below was the "netmask" for the enp30s0 port on the PC. Why is this 0.0.0.0 instead of 255.255.255.0? Rob On Wed, Sep 30, 2020 at 3:00 PM Andrews, Mark J. via USRP-users < usrp-users@lists.ettus.c

Hi Rob, Thanks very much for the response. I checked and by default, in the rfnocmodtool generated verilog for my block, s_out_payload_tkeep is tied to '1'. Also, the autogenerated testbench runs just fine (all tests pass). I poked around at rfnoc_rx_to_file a while ago but didn't spend much t

So, the only other thing I can think of for now relates to issues that I have had in connecting blocks that are not statically connected. For example, the newest default images for the X310 and N310 contain a "Replay" block where the Replay block is connected to/from an end-point in the same way as

[USRP-users] Maximize MIMO Collection with X310

Hello, I am looking to maximize my MIMO collection utilizing a single X310 radio with either 2 TwinRxs installed or 2 UBX-160s installed. In some cases, I have a GPSDO at my disposal. For tasking the radios, I am using python code which creates and runs a GNURADIO Flowgraph. Ultimately, I wou

Hi Rob, Good catch! When I go to the Network Settings under IPv4, I have it set to manual with the static IP 192.168.10.2 and the netmask to 255.255.255.0, but the ifconfig shows that the netmask is still 0.0.0.0.I set it to 255.255.255.0 with a sudo ifconfig command, and after a restart I

Hi everyone, I wanted to know if there is a way to benchmark the performance of different RFNoC blocks? Basically, I want to compare the performance (time taken) by the RFNoC blocks as compared to their counterparts in GNURadio. Also, what factors should I keep in mind that might affect the benchm
