Jonathon, Wade, Regarding the Replay block controller and the recent change on 'master' to Drop property, action, & mtu forwarding, there is one other modification that I think makes sense. The Replay block is the only block controller that implements "issue_stream_cmd" yet doesn't actually registe

Thanks Jonathon! This sure seems like a smoking gun. It doesn't seem like this is an auto-generated file so it seems we could manually modify it to include ports 2 and 3 in the same fashion as the N310 and then rebuild. Is this true? Rob On Thu, Feb 10, 2022 at 4:22 PM Jonathon Pendlum wrote: >

It looks like the problem is that while there is a 4 port interconnect available, only ports 0 and 1 are hooked up: https://github.com/EttusResearch/uhd/blob/2c7ce2dbf72414b64f8a477be614e23bc12f086d/fpga/usrp3/top/e320/e320_core.v#L1050 This actually brings up a design suggestion: the Replay Block

I would start by double checking the YAML. For example, make sure the MEM_ADDR_W parameter is correct (for E320 it should be 31, for 2 GiB) and make sure each in/out port is connected the way you want. If you share the YAML with me, I'm happy to take a look to see if anything jumps out at me. Tha

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

The E320's DRAM is pretty fast. It should have no problem keeping up for your use case. Wade On Thu, Feb 10, 2022 at 1:56 AM Jonathon Pendlum wrote: > Hi Rob, > > As long as the DRAM can keep up throughput wise, you should be fine in > that configuration. I think the E320 has a BIST you can run

Hi Rob, As long as the DRAM can keep up throughput wise, you should be fine in that configuration. I think the E320 has a BIST you can run that reports the throughput. Jonathon On Wed, Feb 9, 2022 at 3:29 PM Rob Kossler wrote: > Hi, > I am wondering if there are any data rate restrictions for
