[USRP-users] Multi-process DPDK support in UHD

Hi all, I have a problem using multi USRPs with multi-processes. I need to use two USRPs connected to a single host, and there are two applications that invoke two USRP with DPDK enabled. The first application successfully started, however when I ran the second one, it gave me the following error

[USRP-users] Parallel streamers on two 10G ports using X410

Hi USRP users, I am using USRP x410 with two 10G ports. And I am wondering is there any way to configure RFNoC streamer so that we can use two ports for streaming parallel? For example, if there are two RFNoC blocks in X410 and two streamer that can stream data to those two blocks in parallel, h

[USRP-users] How to stream large data packet using X410

Hi all, I am currently using USRP X410 with 10G sfp+ cable. I need to stream large data packet at once to my custom RFNoC block, larger than MTU. Is there any way to stream large packet? Now I am just using streamer.send() method to send the data in buffer. But after several times of sending and

[USRP-users] USRP X410 and PCIe connection

Hi USRP user, I am using USRP x410, and wondering is there possible to use PCIe for streaming data instead of sfp+? If possible, is there anyone know how to connect device to the host and what should be the “args” for USRP? Best regards. ___ USRP-user

[USRP-users] Streaming Timeout after two continuous send and receives.

Hi USRP user, I am using USRP X410 with UHD-4.2. I have my own costume rfnoc bitstream. When I test different data for sending and receiving, I have an error of streaming timeout. When I try small size of data, it works fine. But when I try with large size, like over 1 bytes, it cause the st

[USRP-users] Building Bitstream for USRP X410

Hi USRP users, I am trying to build a gain block on USRP X410. When I tried to build bitstream for X410_XG_100, I got the following errors. Seems some IP is locked for USRP X410. Does that mean I need to purchase the IPs for building bitstream? It's odd to me that we still need to buy specific IPs

[USRP-users] How to generate 128 bits CHDR packet and control the metadata?

Hi usrp users, I am trying to build a RFNoC block and because of the IP constraints I need to set the CHDR packet to 128 bits width. I know CHDR support up to 512 bits width, but is there any way to set this? Like UHD API or any other way? Seems like if we does not set up anything, rfnoc will c

[USRP-users] No module named 'uhd'

Hi USRP users, I am currently developing an OOT RFNoC module. When I tried to build a custom image, it gave me errors as below. I checked the python path, and it seems fine. Is there anyone that has any idea of the reason for this? I am using n310 with uhd v4.2.0.0. (I checked with uhd4.0, and did

[USRP-users] Use both RFNoC API and multi_usrp API

Hi USRP users, I am developing a RFNoC block. And for some reasons, I need to use both RFNoC API and multi_usrp API in the application. But I am confused whether we can use these two APIs within one application. For example, the application streams data to  RFNoC block  for IQ processing and str

[USRP-users] The design did not satisfy timing constraints.

Hi, I am building a custom RFNoC block on USRP X310. When I was trying to build bitstream, after almost two hours processing, it gave me the error as below. Do you have any idea what timing constraints are? Is that because the custom IP is too large for FPGA? Thank you! It started after [01:58:3
