My data are too many so the transfer speed is too long and make the processor stop working and cannot continue the calculation. Is that possible?

Is there any tutorial to make it? I don't think so. I have not seen any discussion or tutorial that shows how to do this. I also had looking for the example and cannot found anything. I got an idea to get the manage the uart using the second core of cortex A9, so the first core processor still can do the calculation.

Avnet covers a simple dual-processor example in the Vivado This is available through your local FAE now and will soon be available online here. Thx for the answer. It helps a lot. But I'm from indonesia and I think there is no local fae right now in my country. Is there any other tutorial show me how to use the second core?

Are you using interrupts?

Yes I'm using interrupt. The data is about char. With baudrate I'll get about 34 ms. The data came every 1 s. But I need to a calculation every 25ms.

I'll miss 1 sample every time the data come. Can you guard the critical part of your 25ms routine against interrupts; the FIFO is 8 characters deep; you have a window of about microseconds before you lose serial data?

I need to connect DMA with microblaze. It may help with your design. Hi Thausikan. Hello everyone, i start a new project which i have to read the data coming from many sensor,I need to get data using the UART communication of course i use Microzed in Vivadoand i found it some difficult can you show me or can you guide me please to resolve this problem Any idea where I can get the tutorial to setting the UART?

Hi opoko. The microzed board has a zynq processor. Looking at this Avnet forum thread the pmod port is connected to the ps mio pins. It might be better to use a board that has pmod ports that are connected to the pl. You need to be a member in order to leave a comment. Sign up for a new account in our community. It's easy!

Sign In Sign Up.The simplest usage of a DMA would be to transfer data from one part of the memory to another, however a DMA engine can be used to transfer data from any data producer eg.

Base system project for the MicroZed. Once the bitstream has been generated, we can export our design to SDK where we can develop the software application that will setup a DMA transfer, wait for completion and then verify the loopback. At this point, the SDK loads and a hardware platform specification will be created for your design. You should be able to see the hardware specification in the Project Explorer of SDK as shown in the image below.

The application source code we are using in this tutorial is one of the many valuable examples provided by Xilinx in the installation files. To test the design, we are using the MicroZed board from Avnet. Make the following setup before continuing:. Now you need to open up a terminal program on your PC and set it up to receive the test messages.

Use the following settings:. Now that your PC is ready to receive the test messages, we are ready to send our bitstream and software application to the hardware. The TCL build script and source code for this project is shared on Github at the following links:.

For instructions on rebuilding the project from sources, read my post on version control for Vivado projects. Do you have an axidma application example on linux? Xilinx, even has test kernel module, axidmatest.

Thank you for the tutorial! Is this supposed to be the expected behaviour? However, none of them works. Did you get it finally running in some way? Hi Jeff, thanks for the example. If you are interested contact me at francisco-de-asis. My research is involving working with linux on the zedboard. Did you get that working with AXI stream? I will be glad to discuss this further. Please let me know a good way to reach you. I can be reached on rshah14 gmu. Can you post something related to XIP execute in place for zedboard in steps.

Xilinx provided example is little bit confusing.In a previous postwe made a simple WAV file player. That demo used a fixed sampling rate of 39kHz which resulted from simply dividing the MHz system clock. In order to achieve this, we need to use the PLL which comes with the audio codec. Having the DMA controller running in the background is very comfortable.

But how do you get progress updates? The best way is to use interrupts triggered by the DMA controller. Every project starts with a blinking LED. In this tutorial we create a bidirectional SPI interface. A regular SPI interface receives a word for every word it transmits.

So, […]. We can now exchange […]. Your email address will not be published. Save my name, email, and website in this browser for the next time I comment. In this tutorial we learn: How to change our I2S transmitter to slave mode. How to enable the PLL in the audio codec and change to master mode.

How to adjust the volume using the audio codec. These are the parameters for This is done by polling the lock-bit until it is set to 1. It seems important to wait another 10 ms after enabling the core clock. Or download the complete project further down. Also, remove the bclk and lrclk port. Those ports will change from output to input. Add myI2SSlave. Connect sdata of the IP core to the sdata port. Save the block design Open the constraints file and remove all definitions for the debug cores.

Open the Implementation. Now is a good time to launch the SDK. I encountered problems occasionally that the SDK creates a new system wrapper project. I then have two of those. I found the best way to resolve this was to remove both!Which in general should enable interrupts for finished transactions. Afterward I initialize the interrupt system and register the interrupt for the DMA using the following code:.

The InterruptHandler function itself just counts up a global variable atm and prints somethingbut the function is never called. I don't see any obvious issues with the code that you are using.

It seems to be in alignment with the Xilinx interrupt example seen here:. I do see that SetUpInterruptSystem is being used as an abstracted call to the following two functions:. You might want to take a look at this other thread for issues that others have run into:. Before going further into the software aspect, it probably makes sense to look at first things first and verify that the underlying hardware is performing as expected. I would suggest going through the following checklist in order to verify things are in order:.

I tried to check the interrupt signal of the DMA controller using the logic analyzer, but for some reason i was not able to gather valid data I'm still very new to development using Xilinx tools and FPGA's in general. So I was not able to validate the generation of the interrupt Signal, but I suspect that the DMA core is not working properly.

How can I check the interrupt channel in the HW design? I have only one interrupt signal. The channel in the Software design is 61, which is the lowest channel available at the PS, if I interpreted this correctly.

I managed to identify my problem. I used the wrong address for the reset of the interrupt signal in the interrupt handler. This way the handler was only once every board initialization and got stuck. I ran into another problem which is not totaly clear to me. I designed an own IP core which accepts an axi stream and receives multiple data elements.

Afteward it needs some cycles to process these data number of cycles depend on the specific received data. I thought that setting the tvalid flag of the axi stream to 0 would force the DMA controller to hold further transactions until the core is ready again.

But it seems like the DMA controller is sending data anyway. Hmmm, that other issue goes beyond my knowledge of AXI but I will suggest to you that you start a new thread on the Xilinx forums to address custom IP issues and give the issue some additional visibility. If you decide to go ahead and start a new thread, would you please post a link to it in a reply to this thread here? Hi were you able to find a solution to hold the DMA transfer while some processing is happening and then continue???
