Getting Started Guide for Xilinx Zynq 7000 ZedBoard
This guide is meant to be used as a reference on how to start using RidgeRun's SDK over AVNet/Digilent Xilinx Zynq 7000 ZedBoard hardware. The first section of this guide shows some general guidelines on how to work with our SDK as well including some very basic procedures that need to be execute before installing / trying to build RidgeRun's SDK (for example setting up a TFTP and NFS server or installing Xilinx ISE tools). Later on, the second section contains instructions about how to configure the SDK to a create a SD card with all the key software components (bootloader, kernel and file system) needed to boot all the way to Linux's shell in the evaluation board.
Please take notice that in the following sections it is assumed that the user has already downloaded and installed Xilinx Vivado ISE Design Suite in the development machine, this is remarkably important since these tools also include the toolchain required to cross-compile the SDK. For this guide, Vivado Design Suite 2012 and ISE Design Suite 14.4 was used; it might be the case that the developer has acquired a more recent hardware revision board with a newer set of tools, in case problems arise for this reason please do not hesitate to contact RidgeRun for further asistance.

Basic preliminary work
Installing Xilinx ISE Tools
As mentioned earlier in the Introduction, it is assumed that the developer has acquired an AVNet / Digilent Zed board. In such case please proceed to use the DVD labeled for Linux in order to install the corresponding Vivado and ISE Design Tools from Xilinx in your Ubuntu desktop and execute the xsetup binary file to start installing the Xilinx Tools.
$(USER)@$(HOST):cd /media/Xilinx_ISE_DS_Lin_14.4_P.49d.3 $(USER)@$(HOST):/media/Xilinx_ISE_DS_Lin_14.4_P.49d.3$ ./xsetup
To check for the latest versions of the Vivado / ISE Design suite please refer to the following link:
Some additional hints for Ubuntu 12.04:
Linux Host Setup
- Configure TFTP:
If you are planning to use the SDK's installer to install images generated by the SDK in NAND, installing a TFTP server you will speed up downloads to the target hardware by using TFTP.
- Configure NFS:
For application development, it is convenient to use root NFS mount file system for the target hardware. This allows you to rebuild your application on the host and immediately run the application on the target hardware with no interveining steps. You host PC needs to be configured as a NFS server for this in order to work properly.
- In case termnet is preferred over minicom as serial console / terminal app, please refer to the short guide below
TERMNET terminal app configuration, alternative to minicom
Please skip below two steps (3.3 and 3.4) and jump to 3.5 if you have purchased a Professional SDK.
Getting the RidgeRun's EVAL SDK Irazu
If you want to get the RidgeRun's EVAL SDK Irazu you need to go to our Evaluation SDK Download Link and select the Evaluation SDK you need. You will be asked for your email address and some information. Once you have submitted the required information you will receive an email with the following information:
Sequence of evaluation sdk download events:
You have to follow the steps below :
When you select and click on the name of evaluation sdk you want to download, shopping cart page will display with the price $0.00 (for eval sdk's)
-> click on 'Go to Checkout'. It will display 'Your Shopping Bag' page
-> click on 'Checkout'. You will get a form to enter your email id and other info
-> click on 'Continue'. It will display a 'Place Order' page
-> click on 'Place Order'. And then Please check your email with a link to download the tar file for the evaluation SDK you have selected.
Installing the EVAL SDK
RidgeRun delivers the SDK in either two ways: a tar file for x86 platforms, or for customers with a established development relationship through a custom SCM (typically GIT) repository. If you are using a shared SCM repository, please contact RidgeRun for a detailed instructions.
Listed below are the minimum recommended requirements for installing and using the RidgeRun SDK:
- A host computer with a 686 or better family processor
- 1 GB free hard disk space
- A Linux distribution configured on the host computer.
- Target hardware for the SDK
- Optional: a network card installed and configured on the host computer
- Optional: Internet connection for SDK updates
Once you have downloaded the tar file of the evaluation SDK you can untar it by running the following command:
tar -xvzf <name of the tar file downloaded>.tar.gz
You may find it convenient to untar the evaluation SDK more than once. For example, you might want one version to be unmodified and another version to be your working development directory. RidgeRun suggests you untar the SDK development directories in your $HOME/work/ directory. When you have more than one development directory installed, just remember to have the DEVDIR shell variable set properly. To set the DEVDIR shell variable use the `make env` command specified at Build_SDK
On the rest of this document, we refer as $DEVDIR to the path where the RidgeRun EVAL SDK for the Zynq 7000 Zed board is installed.
Installing the Professional SDK version
When all the purchase process is done, RidgeRun will provide you a GitHub repository access. For that, the GitHub user ID and other information might be requested. Once you provide that information, you must clone the given repository URL, using the next command:
git clone email@example.com:RidgeRun/<customer>.git
This would have the proper <customer> space modified. With this, you will have the SDK installed on the directory you were when executed the clone command.
RidgeRun suggests you untar the SDK development directories in your $HOME/work/ directory. When you have more than one development directory installed, just remember to have the DEVDIR shell variable set properly. To set the DEVDIR shell variable use the `make env` command specified at RidgeRun_Irazu_SDK_User_Guide#Build_SDK.
On the rest of this document, we refer as $DEVDIR to the path where the RidgeRun Professional SDK for the Zynq 7000 Zed board is installed.
Running RidgeRun SDK
Configuration and build
Please refer to the link below for information on how to configure and build the RidgeRun SDK for the first time:
Booting from SD Card
Setting up Zynq 7000 ZedBoard to boot from a SD card
In order to boot from a SD card you need to set the SD port as the first boot device to try in the Zynq 7000 boot sequence. The ZedBoard uses MIO[5:3] to select the boot mode, SD card boot mode is selected by setting the MIO[5:4] to 3.3V (logical 1) as shown in the image below:
Configuring SDK to deploy firmware to a SD card
1. Set your environment variables
cd $DEVDIR `make env`
2. Open a configuration menu
3. Proceed to the Installer Configuration sub-menu and set the Firmware deployment mode to Deploy all the firmware to a SD card option as shown below:
4. Proceed to the Toolchain Configurations sub-menu and make sure that you have the right binaries path for your toolchain. For this option, what usually changes is the version of ISE installed:
The RidgeRun SDK offers basically 2 ways of creating a bootable SD card:
- By creating a SD card image by creating a loopback device (later on this image is burned into the SD card using dd command.
- By storing the firmware images into a previously partioned (by the SDK) SD card.
For more information about the main configuration settings related to SD card installation options, please refer to the link below:
How to boot from SD card using RidgeRun SDK
Booting the Zynq 7000 ZedBoard running RidgeRun SDK
Once the SD card build process is complete, proceed to boot the board:
1. Open your serial console / terminal emulator (minicom, terment, picocom depending on your preference).
2. Insert the SD card into the SD card slot in the Zynq ZedBoard, power ON the board a wait for the board to boot all the way to the Linux Kernel prompt. The log should be similar to the following:
