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.

Any feedback regarding my three questions is apreciated. We have detected your current browser version is not the latest one. I’m not quite sure why that is happening.

Xilinx AXI Datamover | IP Catalog

As a result, I created a bit value that is a concatenation of the bit along with a bit count which is the value I am sending to the datamover DMA over AXI-Stream. After that I just use a pointer to read out the contents of memory location 0x Revision History The following table shows the revision history for this document. My idea to handle this would zxi to create a 2 AXI slave and 1 AXI master aximm interfaces in a “pass-through” component that just hooks the 5 buses together 3 from write, 2 from read.

The command word settings are as follows: Same problem I indicated here persisted with no obvious solution, so he provided a complete different approach based on code he had written in the past that is non-DMA dependent.

Sorry, you need to enable JavaScript to visit this website.

I am receiving a bit value at the rate of 1us. Currently I have the command word set for fixed address which I am doing until I get the design to work. Actually I do disable cache in my code before reading the memory location simply by including the following:. Please upgrade to a Xilinx. Additional Resources The following information is listed for each version of the core: I’m facing a similar situation and I’m curious to see how you fixed it. I am keeping a count of the 1us clock cycles to enable me to do that.


I have been trying to debug with Chipscope as well but with no luck so far.

To the maximum extent permitted by applicable law: I would really appreciate more insights getting the datamover to work has axl really frustrating. Here is what I am trying to do with my design:. Maybe some other ways to achieve similar effect?

For the mean time I have to settle with simulation to determine what is going on. 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. ChromeFirefoxInternet Explorer 11Safari.

I looked into aix again and seems I finally managed to get it somewhat working. All forum topics Previous Topic Next Topic. It sounded like it would be sufficient for my purpose.

I’m sorry for the extra late reply, I was away from the lab for several weeks. Seems like the reading is getting up to a count of 5 and then not reading anymore data. Auto-suggest helps you quickly narrow down your search results by suggesting possible matches as you type. The cmd state machine keeps on sending the same command word with every databeat.

Slave interfaces may not define Metadata until Validation has been run As I am connecting a normal fifo to this input, which is not master axi, then I created an AXI fifo, with the correct width, validate, erase and finally with the correct width connect my normal fifo in the place I had it before.


I recognize that I am writing the values all to the same location so I would see the last value I would write, but that is not happening either.

I would really appreciate some insight on what might I do to solve the problem. AXI interconnect and DataMover. We share info about use of our site with social media, ads and analytics partners.

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? I am trying to create a design using the AXI datamover in a Zynq design using a zedboard yet I am really struggling.

Please upgrade to a Xilinx. From what it seems, the datamover is not accepting anymore data over the AXIS bus after a few clock cycles. I setup the datamover in S2MM basic mode mhs attached as well. Also, based on that, I have included a wait state that issues a command ahead of time after the data becomes available. The VHDL code now does the following:.
