I think 3.11, but how do I check? I'm not sure if I mentioned or not, but I am running benchmark_rate from a host, not embedded. Rob On Thu, Jul 19, 2018 at 6:03 PM Martin Braun wrote: > On 07/19/2018 02:50 PM, Rob Kossler wrote: > > Oops, I meant to say in the last email that I had confirmed t

Re: [USRP-users] N310 with rfnoc-devel branch

Oops, I meant to say in the last email that I had confirmed the other fixes - sorry about my misleading remark. Yes, I tried with externally supplied PPS and configured with time_source arg setting. Same result as with internal PPS. Rob On Thu, Jul 19, 2018 at 5:46 PM Martin Braun wrote: > On

Hi Martin, I wanted to confirm that the recent fixes mentioned for some of the N310 issues I mentioned are indeed working well for me. These include - Tx power output levels - get_usrp_rx_info(), get_usrp_tx_info() However, I am still stuck on this "No PPS Detected" error which occurs in the funct

Re: [USRP-users] rfnoc debug block

I was wondering if anyone had thoughts on this? I am now seeing it on a brand new block that I tried to create today. A uhd_usrp_probe looks fine, but when I run the python generated by GRC, I am seeing the same error: Traceback (most recent call last): File "/home/jmat/rfnoc-nocblocks/example

[USRP-users] Dual TX/RX with one vs multiple multi_usrp objects

Hi, I am running tx and rx on both channels of an X310 and I am trying to run as fast as possible. I have one thread handling each tx or rx, so four threads total. Originally I was using one multi_usrp object and each thread would create a rx_streamer or tx_streamer from that multi_usrp. Howe

I have a silly question. How do I add the axi_dma_fifo to my build? It looks like we can't add it to the uhd_image_builder command line, so I am not sure the way to do it manually. Is this written up somewhere that I missed? ___ USRP-users mailing li

Re: [USRP-users] TDMA receiver on E310

Hi David, so, NUM_SAMPS_AND_DONE sounds right for this application, and pre- determining the time at when the observation will start with time_specs sounds absolutely like what I'd recommend. You say there's a "delay when leaving the recv function"; I'm not quite sure I understand what you're ref

[USRP-users] TDMA receiver on E310

Hi. We have implemented a TDMA receiver on an E310. We have to receive slots of 40 ms duration and we must capture and process each of them. These capture instants must be very precise, so we have used GPS to discipline the internal clock of the E310. What is the most appropriate stream mode for
