Re: [USRP-users] using 'replay' block with 'duc'

Hi Wade, I am still not able to get the attached example to work. As indicated in my original email, I modified replay_samples_from_file to add a DUC block in between the Replay and Radio blocks and also added a loop to provide repeated start/stop of streaming. It works fine the first time but th

Yes, this is intentional. There is a lot of active development going on for UHD 4.0 and the Replay block will be in there soon. Thanks for the details with respect to port > 1. I will let you know what I find. Wade On Fri, May 1, 2020 at 1:22 PM Rob Kossler wrote: > And, one more thing Are

And, one more thing Are you aware that the current 'master' (UHD 4.0) provides images that do not have the replay block on them (e.g., N310) and that there is no noc_block_replay.v or replay block HPP file anywhere in the repo? Rob On Fri, May 1, 2020 at 1:28 PM Rob Kossler wrote: > Hi Wade,

Hi Wade, The issue can be demonstrated using the stock "replay_samples_from_file" program (N310 UHD3.15). Run with "trace" logging if you want even more detail. So, it's not really an issue related to multiple ports. It's an issue of connecting Replay port 2 (or likely port 3 as well) to an arbi

Thanks Wade, A few follow up questions: - Regarding play_halt(), it sounds like this should never used if you are planning to start playout again (and the replay output feeds the DUC input). Is this correct? Or perhaps there is some way to clear the DUC? - In the meantime, what is th

Hi Rob, I wanted to give you a quick update. I was able to reproduce the issue you found. There were two problems. First, the example you shared calls play_halt() for the replay block each time replay is stopped. This basically stops it as soon as possible, even if that means it can't send a fina

Hi Rob, Thanks for the example! I'd take a look to see if I can reproduce the issue and figure out what's going on. I've been working recently on the Replay block, so I'm very interested to understand what's going on. Thanks, Wade On Thu, Apr 23, 2020 at 1:36 PM Rob Kossler via USRP-users < usr

Hi, I am having an issue with UHD 3.15.LTS using the replay block. When I play out my previously stored samples the first time, everything works fine. But after stopping the first time, if I try to start playing out again, I get a whole bunch of 'Lates' and no RF output. In order to duplicate the
