Thanks Wade, I am helping Ofer Saferman with an issue with the E320 and a 4-port replay block. Apart from your response (& Jonathon's response) indicating that data rates should not be an issue, I have also come to the same conclusion by trying some tests. After these tests, the issue now seems to be that Replay ports 0 and 1 work as expected, but Replay ports 2 and 3 do not. I know that a 4-port Replay block works fine on an N310 because I use it often. So, I'm wondering why we have this issue on the E320. Perhaps the E320 yml file is wrong - I am still waiting to take a look at this. I have also requested that Ofer run the stock example "rfnoc_replay_samples_from_file" and use the --replay_chan option to prove that ports 0 and 1 work fine but ports 2 and 3 do not.
Anyway, if you have any suggestions, I'd love to hear them. Rob On Thu, Feb 10, 2022 at 11:17 AM Wade Fife <wade.f...@ettus.com> wrote: > The E320's DRAM is pretty fast.
