The good alternative was to use the AXI Data Mover. – The transfer commands are delivered by AXI4 Stream. – The status of transfers are delivered back by. The AXI Datamover is a key Interconnect Infrastructure IP which enables high throughput transfer of data between AXI4 memory mapped domain to AXI4- Stream. For you, you are probably looking at AXI Datamover or AXI Central DMA. ” Xilinx provides the AXI Virtual FIFO Controller core to use external.

Thanks a lot for your timely and useful assistance.
If you don’t use the sts busses inside your design i. Your suggestions, indeed, solved the issue. Please upgrade to a Xilinx. I will need to do that for a maximum ofclock cycles ms.
We have detected your current browser version is not the latest one. Here is what I am trying to do with my design: AXI interconnect and DataMover.
Also, based on that, I have datamovet a wait state that issues a command ahead of time after the data becomes available. I would really appreciate some insight on what might I do to solve the problem. Embedded Processor System Design: However, when a second write command is issued, the tready signal of the s2mm bus is deasserted, and never asserted again. Afterwards, and since I am sending bit word at a time, I will include the logic to keep on incrementing the SADDR every time I receive a new data word to send.
Xilinx assumes no obligation to correct any errors contained in the Materials or to notify you of updates to the Materials or to product specifications. When datzmover state that you are using SDK to read memory datamoevr 0x, you do not say how.
After a all the Chipscope issues, I decided to start a clean slate project in Vivado and try out the logic analyzer instead. The cmd state machine keeps on sending the same command word with every databeat. All other trademarks are the property of their respective owners. I use the regular fifos as I need to cross clock domains and change the data width accordingly to mantain my throughput.
I finally managed to get some more insights on what is happening.

I am on a similar project but need a little bit more time to tell if it works as expected. It also seems like the rest of the signals are correct.
Auto-suggest helps you quickly narrow down your search results by suggesting possible matches as you type. To the maximum extent permitted by applicable law: It’s the mechanism to propagate various parameters like data width. Then the datxmover would move its width down to the datamover.
For some reason I could not arm the core or get it to trigger. I’m facing a similar situation and I’m curious to see how you fixed it.
I have a state machine running for the data that would send a bit data word every time a new value becomes available. I am receiving a bit value at the rate of 1us.
But thanks to your sugestion, Asi tried once more with no result. I’m not quite sure why that is datamovee. We share info about use of our site with social media, ads and analytics partners. Any feedback regarding my three questions is apreciated. I was not aware that the status interface had the ability to prevent data from being transferred.
Could this still be the issue? ChromeFirefoxInternet Explorer 11Safari. Please upgrade to a Xilinx.
Still working on it though. I do realize that in the PG there is a note saying:
