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.

The command word settings are as follows: I’m facing a similar situation and I’m curious to see how you fixed it. Embedded Processor System Design: You may not reproduce, modify, distribute, or publicly display the Materials without prior written consent.

If you don’t use the sts busses inside your design i. Here is what I am trying to do with my design: Thanks a lot for your timely and useful assistance. The VHDL code now does the following: ChromeFirefoxInternet Explorer 11Safari.

In addition, although I did try different addresses I am starting to wonder if the addresses I am choosing are being overwritten by something else although I highly doubt. Though in simulation I havent gotten to see any datamover responses.

AXI interconnect and DataMover.

Embedded Processor System Design: I’m not quite sure why that is happening. I looked into it again and seems I finally managed to get it somewhat working. For the first occurrence of each acronym, spelled out the occurrence followed by the acronym.

But thanks to your sugestion, I tried once more with no result. For the mean time I have to settle with simulation to determine what is going on.

Actually I do disable cache in my code before reading the memory location simply by including the following:. Maybe some other ways to achieve similar effect? I am receiving a bit value at the rate of 1us. I’m sorry for the extra late reply, I was away datamkver the lab for several weeks. I recognize that I am writing the values all to the same location datamiver I would see the last value I would write, but that is not happening either.

datanover I greatly appreciate your help. After a all the Chipscope issues, I decided to start a clean slate project in Vivado and try out the logic analyzer instead.

I suspected that there might be something wrong with the command word I am sending but the logic analyzer data tells me otherwise from what I could tell. It is illegal for the core to deassert tvalid until tready accepts it. When you state that you are using SDK to read memory location 0x, you do not say how.

ChromeFirefoxInternet Explorer 11Safari. I have been trying to debug with Chipscope as well but with no dataover so far. It’s a bit strange that the second transfer cannot be executed, since a the FSM goes through through the same steps in the second iteration as it did in the first one, so the protocol is being followed, and b as far as I understand, there’s no need to do any kind of inter-transfer [re]initialization of the DataMover block or is there?
