Re: [USRP-users] Netgear 10GB switch XS728T

Kevin, I glanced through Captures 0,1,2 and could see the general gist of where it all goes wrong, but it’s not really clear why. The dissector seems out of date, at least it isn’t decoding correctly but I can still follow it. Capture 0: Packets 2551 through 2606 are the actual sample data

Re: [USRP-users] Ethernet over SFP+ in custom FPGA design (X3x0)

Christian, CHDR packets are encapsulated in UDP/IP between Host and USRP. See the attachment. PHY+ MAC functionality live under the x300_sfpp_io_core. However these blocks do not encapsulate/decapsulate the network packets. All the ethernet/IP/UDP framing fields are added by chdr_eth_framer on

Re: [USRP-users] USRP2 schematic vs. FPGA source discrepancy

BTW. I found that this question has been already asked a long time ago: https://lists.gnu.org/archive/html/discuss-gnuradio/2010-09/msg00056.html but it didn't get any answers back then. Thanks Ian for the full explanation. 2017-11-09 10:15 GMT+01:00 Ian Buckley : > >

Re: [USRP-users] USRP2 schematic vs. FPGA source discrepancy

There’s a bit of history there. PHY_CLK was indeed originally connected to the FPGA. It wasn’t needed and so the S1 switch was added to that pin instead. That switch was never used and so the original signal name persists in the Verilog even though it connects to nothing. -Ian > On Nov 5,

[USRP-users] Compiling UHD Host Library: Problem Enabling ARM Neon Support

I have noticed that neon support for the converter is not enabling. The CMakeError.log has this output. I am not certain as I am not really familiar with ARM and NEON, but I checked my CPU and it does support it. Also, the error message below is saying it is just a matter of passing certain flags.

I want to contribute a fix to https://github.com/EttusResearch/fpga repository. However, given my agreement with the company I work for, the process of submitting the patch might be different depending on the license of the project I want to contribute to. My assumption would be that the license

[USRP-users] Access .sob, .eob, or RFNoC Data from Host?

Hello. I'm trying to access RFNoC data from across the host boundary within gnuradio but am having trouble figuring it out. Specifically, I'm setting the .sob and .eob in RFNoC and trying to get that data within a host-side C++ gnuradio block. I found a gnuradio struct called

Re: [USRP-users] Sync two USRP devices to sense 100MHz of spectrum

Hello Wahhab, I do not know about using the MIMO cable between a USRP2 and a N2x0, the USRP2 became end of life before I started at Ettus. I think it would work, but cannot test it myself. Others at Ettus may know the answer. You will need at least two 1 Gigabit connections to your host

Hi Manuel, Is it possible to include "LICENSE.md" file in the repository? It seems that GitHub even has a tool for that: https://help.github.com/articles/adding-a-license-to-a-repository/ Thanks, Michał 2017-11-09 15:36 GMT+01:00 Manuel Uhm : > Hi Michal. > > UHD and

[USRP-users] Sync two USRP devices to sense 100MHz of spectrum

Dear All, We would like to sense (i.e. sample) 100 MHz of 2.4GHz spectrum. My idea is to connect 2 USRPs (USRPN200 and USRP2) via a MIMO cable (available at ettus.com). Then, we configure each USRP separately to monitor 50MHz of bandwidth (8bit per sample). My question: 1- is it possible to

Re: [USRP-users] Sync two USRP devices to sense 100MHz of spectrum

Thank you Derek for the comments. I just want to clarify this point about connecting two USRP devices; first, it seems to be fine to connect a USRPN200 with USRP2 (via a MIMO cable), right? Second, by connecting two devices via MIMO cable, I need to connect their GigaBit Ethenet cables to a

Re: [USRP-users] Error when burn fpga image file into USRP X310

Did this ever get resolved?  Because I am having the same issues now too. Hi Luis, I will follow up with you on this issue off the list, within the thread that has been sent to support at ettus.com.

[USRP-users] Inquiry into using RFNoC in UHD 3.9

Hi, Due to recent changes in design flow, our team recently moved from UHD 3.10 to UHD 3.9. I was just wondering how would one develop FPGA modules (or integrate RFNoC modules) on UHD 3.9? Thanks, Manik Singhal ___ USRP-users mailing list

Robin and Marcus, Thank you for the suggestions. Marcus, I did try and follow your suggestion, however, I cannot communicate with the N210 other than through the Jtag port communication. Robin, I did install the Xilinx ISE 14.7 Labtools and ran Impact, however, I kept getting a windrv6

[USRP-users] Dual 200 Msps transmit on X310

Hello, I am trying to TX two streams of 200 Msps on the X310. There is no RX. It does not work. I recall hearing that there is a fundamental limitation of the FPGA crossbar that limits total TX (both channels to 200 Msps). Is that the case? What can I do to work around it? Perhaps a

Re: [USRP-users] Compiling UHD Host Library: Problem Enabling ARM Neon Support

I was able to get the compiler flags passed in so that the check for the header arm_neon.h passes. I added it to the CMakeList root file with SET(CMAKE_CXX_FLAGS, "${CMAKE_CXX_FLAGS} -mfloat-abi=softfp -mfpu=neon"). Then, it would detect neon. However, I spent considerable time cleaning up
