Zedboard fpga tutorial

By Doum

The board used in the examples is the ZedBoard, but you could use pretty much any ZYNQ development board that supports Pmod interfaces. Links to these products are provided below.

This tutorial will also uses two Digilent Pmod boards. You can follow along with the tutorial using either Linux or Windows. I use Linux so the examples may be biased in that direction.

However, I will also try to provide links and tips for using Windows. You will need to download the Xilinx Vivado software from the Xilinx website. Make sure you download release Follow the directions that come with the board to redeem your license. Before starting on this tutorial, you should do the first tutorial on the ZedBoard site.

That will get you familiar with using the Vivado IDE. Specifically you need to learn how to create a project and program the board. Once you have mastered that, you can get started on the tutorials here. Pingback: LEON3 gumdaeng. Hello, I am working on zynq zc I think if you follow the tutorial you will learn how to do this. Hi pete, Can you give me some suggestions using SPI how to do accordingly i will proceed.

You just need to combine these techniques to make a SPI interface. It would have registers to control the data you want to send or read the data you have received.

In addition you would need some control registers to start the transmission and control various aspects of your logic — like the SPI clock rate for example. Have you worked through all the tutorials? It is important to really understand what you are doing.

Otherwise you will always be limited to using only the Xilinx IP or things you can copy from others. Hello, I gone through tutorials butn i tried to design the same block in vivado as shown in tutorials for I2S but i am not able to do the same in vivado But I thought you wanted a SPI interface. I am not sure why the tutorials would not work in Vivado It is hard to give you more advice on your SPI interface without knowing what your requirements are.

How to do this any suggestions? The ZC? You can then use them from software on the ARM. I have a customer right now that may need help doing this as well.

If I need to help them with it then I can offer more specific help to you or write a blog post about it. But for now there is not much more that I can do to help. Hi Pete, I have a project with ZedBoard for my final year project. The modulated signal is then sent to the Line Out port of the zedboard.

Can you please give me some ideas on how to imoplement this? I am assuming that you will transmit the line out signal over some type of RF link and then convert it back on the receiving end. My guess is that you would design your FSK block to take the serial data and encode it and using an AXI streaming interface.

You need to make sure that the rate out of your FSK block matches the rate in for the I2S transmit unit.

It should be pretty straightforward.The controller will be coded using VHDL. Download the VHDL files for the project zip file : here. An image is an array of pixel for pi cture x el ements. For a Black and white image, a pixel is defined by one value representing the luminosity.

If this value is high, the pixel will be bright white and if it is low, the pixel will be dark black. For a colour image, in most cases the pixel is composed of three values: its level of Red, its level of Green and its level of Blue this is why we usually call colour images RGB images for Red Green and Blue. The combination of these 3 values will give the final colour of the pixel. For example, in a lot a software tools, you can create customs colours by setting the value of Red, Green and Blue.

As shown in the Figure 1, if you select the maximum value for Green and Blue in this case and 0 for Red, you obtain the colour cyan. To display an image on a monitor, the image is sent line per line, starting with the top one and each line is sent pixel per pixel, starting with the left one.

For example, the Figure 2 shows how a 3x3 pixels image could be sent to a monitor using 3 data lanes Red Green Blue. A video frame one single image of a video comprises active video and blanking periods no data sent. The Figure 3 shows an example of a video frame along with the synchronization signals. During the Active Video period, the data are sent to the monitors. These pulses can be positives or negatives depending on the output video format. The periods before a synchronisation signal and after a synchronisation signal are called respectively Front Porch and Back Porch.

On the ZedBoard, these values are sent using a 4-bit input Digital to Analog converter as shown on the Figure 4.

For this tutorial, we will output a VGA signal with the output format x 60Hz. In this format the pixel are send with a With the output format x 60Hz, the size of the active line is pixels, the horizontal synchronisation signal, which is negative, is sent after clock signals in the blanking period, and last clock signals and there are clock signals between the horizontal synchronisation signal and a new active line.

The Table 1 summarise the horizontal timing. Table 1 - x 60 Hz Horizontal timing. With the output format x 60Hz, the size of the active frame is lines, the vertical synchronisation signal, which is positive, is sent after a period corresponding to 1 line signals in the blanking period, and last for a period of 3 lines. This synchronisation signals is followed by a period corresponding to 33 lines before a new active frame.

The Table 2 summarise the vertical timing.

As we need a Firstly, we have a MHz clock in input but we need to convert it to a You should see the hierarchy showed in the Figure 10 in the Sources window. Connect the ZedBoard to a monitor. You should see a green screen on the monitor. If this is not working, try the Bitstream from the downloaded folder.

Figure 1 - Example of custom colour definition tool To display an image on a monitor, the image is sent line per line, starting with the top one and each line is sent pixel per pixel, starting with the left one. Figure 3 - Example Video Frame and Synchronization Signals The Figure 3 shows an example of a video frame along with the synchronization signals. Timing information x 60Hz For this tutorial, we will output a VGA signal with the output format x 60Hz.Hi, I am having problem with my rev D zedboard.

You have not given us much to go on. What version of the Xilinx tools are you using? That said there are a couple of things to look at. You may also need to allow the firewall to make the connection. If you still have issues you might want to try a different tutorial to make sure you have generated a valid FPGA config file. Thanks Gary.

Zedboard Tutorials

The usb-uart connection to j14 works ok so it is not the cable or the usb port. You did not mention which Xilinx tools version you are using. Also using Windows 7 I do hear a notification and see the USB serial converter connection in the Device Manager but do not get a 'hardware detected message'. Using a predefined zedboard hardware platform should rule out any errors you may have made in generating your design.

First start up SDK no need for a Vivado design for this exercise. Setup a workspace directory for your experiment. Select 'Hello World' and then 'Finish'. In the XDM console that opens type "connect arm hw". I used the connect arm hw command in XDM and it worked.

Many thanks for your help. I am having problem with my rev D zedboard. I have windows 10 and the version of the Xilinx tools that I use are Vivado I checked every thing but it does not work. So, what is wrong? Also, If you have video or picture, please send it to my email : jhs.In this tutorial, we cover installing PetaLinux on your build machine and making a Linux build for your ZedBoard.

We will then write some code to control the FPGA we built in the previous tutorial. You can find the You should modify the commands below for your particular installation directory.

After downloading the PetaLinux tools, run the following command to install them. This will take quite a while to verify the package contents and then ask you to accept some license terms.

Once the PetaLinux tools are installed, you also need to install the board support package. That is just a single file which I copied into the install area like this:. The PetaLinux tools have a shell script which you can use to set your shell path and environment variables.

To do that, run the following in your shell:. You use the petalinux-create command to create a project. Once you have created your PetaLinux project, you need to configure the Linux build. To do that, you run the petalinux-config command like this. We need to point the PetaLinux configuration process to that exported design.

So I used the following command:. This will bring up a Linux menuconfig utility. You can use this to configure options for your Linux build. For now, just use your arrow keys to select Exit and then press return. Run the following command:. Use the arrow keys and spacebar to select both dropbear and the bropbear-openssh-sftp-server. Then select Exit. Continue to exit pages until you exit out of the menuconfig process. Select Yes to save. This will configure the build to enable the ssh server and the ability to ssh out of the ZedBoard.Each link has read me files instructing to build the complete project.

Here, the GPIOs i. Each bit bank independently controls 32 EMIO pins with each pin can be configured either input or output at a time. You would have the following beautiful figure. Lastly, export hardware and launch the SDK. In SDK environment create application project and select hello world and finish it. Copy the code following code and paste it into helloworld. Lastly, the GPIOs are implemented by making use of Vivado and Zedboard as a software and hardware platform respectively.

To facilitate the learners, this tutorial is sub-divided into three parts:. The IOPs e. The processor system PS part of Zynq has many built-in IOP controller with each controller provides its own driver available in the form of C code, enabling the users to integrate the external IOPs with PS without any extra overhead.

In the following tutorials, we will be using these drivers to configure external IOPs. The MIO pins however are limited in number. Xilinx also provides its solution by introducing EMIO pins. Their application includes but not limited to monitor and control the other circuitry. They can be used to implement low data rate communication standards e. The GPIO is organized into four banks of registers that group related interface signals.

Each GPIO can be independently and dynamically programmed as input, output, or interrupt sensing. Functional Description of GPIO banks: All the registers used to configure GPIO bank s bank0 and bank1 are shown in the following figure and the functions of the registers are summarized as follows:. PS literally employs to implement software functions of a hybrid system while hardware related functions are realized in PL.

Coherency ensures that caches in the respective CPU have updated data. L2 caches further act as bridge between L1 cache and DDR ram. DDR ram are relatively bigger memory e. Additionally, Timers private timer, TTC can be employed as timer or counter.

The key feature of MMU is the address translation.This book comprises a set of five tutorials, and provides a practical introduction to working with Zynq All Programmable System on Chipthe family of devices from Xilinx that combines an application-grade ARM Cortex-A9 processor with traditional FPGA logic fabric.

The tutorials target two popular Zynq development boards: the ZedBoardand the lower cost, Zybo. Working through, the reader will take first steps with the Vivado integrated development environment and Software Developers Kit SDKand be introduced to the methodology of developing embedded systems based on Zynq. T he Zynq Book Tutorials can be obtained either through the free downloador in physical form in pages of full colour print.

Click Toolbar. Remember than in C everything is addresses. That means you can call a function if you have the address. It exports the address of a function so that driver functions can be called without having to place header declarations since those functions are sometimes not know at compile time. In cases like this the static qualifier is just made to ensure that they are only called through this method and not from other files that may include that driver code in some cases it's not a good idea to include driver code headers and call them directly.

Driver functions are usually not called through userspace directly except for x86 implementation of SYSCALL instruction which does some little tricks to save the context switch sometimes. So the static keyword here makes no difference. It only makes a difference in kernel space. Skip to content.
