Zynq design from scratch. Part 22.

Installing PetaLinux

The PetaLinux Tools offers everything necessary to customize, build and deploy Embedded Linux solutions on Xilinx processing systems. Tailored to accelerate design productivity, the solution works with the Xilinx hardware design tools to ease the development of Linux systems for Zynq®-7000 All Programmable SoC, MicroBlaze and PowerPC.

PetaLinux for MicroBlaze

I have already used PetaLinux in my FPGA design from scratch blog to run Linux on MicroBlaze.

Spartan 6 LX9 MicroBoard
SP605 Spartan 6 FPGA Board

Download PetaLinux installer

Let's go to the PetaLinux download page.

1. Download PetaLinux 2013.10 Installation archive for Zynq and MicroBlaze.

2. Download PetaLinux 2013.10 Board Support Package for Avnet/Digilent ZedBoard.

PetaLinux documentation

Let's start by studying the PetaLinux documentation page.

PetaLinux wiki

Here is a link to the Xilinx PetaLinux wiki.

Prerequisites

The getting started document assumes that the following prerequisites have been satisfied:

Minimum workstation requirements:

2GB RAM (recommended minimum for Xilinx tools)
Pentium 4 2GHz CPU clock or equivalent
5 GB free HDD space
Supported OS:
RHEL 5 (32-bit or 64-bit)
RHEL 6 (32-bit or 64-bit)
SUSE Enterprise 11 (32-bit or 64-bit)
PetaLinux release package downloaded.
Valid PetaLinux license.
Common system packages and libraries are installed on your workstation. The installation process will check for these.

Ubuntu Linux is not mentioned but I am quite sure we will manage to use Ubuntu. I have done it in the past.

PetaLinux license file

To use PetaLinux we need to install a license file. Let's go to theXilinx Get License File page.

We will apply for a one year free node-locked license (which can be renewed after one year). Click Generate Node-Locked License.

Add a new host

To add a new host we have to provide the hostname and the hostid (HWaddr). Here are the commands to find them:

hostname
ifconfig

Click Next to continue and download the license file Xilinx.lic (see Vivado installation).

Merging license files

The Vivado WebPACK and PetaLinux license files can easily be merged together just by copying the content from one of the files to the other.

PetaLinux installation

Let's start by reading the PetaLinux SDK User Guide: Installation Guide. We will install PetaLinux in the directory /opt/PetaLinux

cd $HOME/Downloads
sudo ./petalinux-v2013.10-final-installer.run /opt/PetaLinux

Packages required by PetaLinux

PetaLinux requires a number of standard development tools and libraries to be installed on your Linux hostworkstation. The PetaLinux installation process checks for these packages, and reports an error if any are missing, however it does not attempt to install them - you must do this manually. This section describes the required packages, and how to install them on different Linux workstation environments.

I installed the following libraries and programs before installing and running PetaLinux.

sudo apt-get install gawk
sudo apt-get install bison
sudo apt-get install flex
sudo apt-get install zlib1g-dev
sudo apt-get install tofrodos
sudo apt-get install libstdc++6:i386
sudo apt-get install libncurses5:i386
sudo apt-get install libncurses5w-dev:i386
gcc was uninstalled so install it again
sudo apt-get install gcc

Here is the PetaLinux installation directory structure.

Setup PetaLinux SDK working environment

To setup the working environment we source the setup script:

source /opt/PetaLinux/petalinux-v2013.10-final/settings.sh

BSP installation procedure

Included are reference designs for us to start working with and customise for our own projects. These are provided in the form of installable BSP (Board Support Package) files, and include all necessary design and configuration files, including pre-built and tested hardware and software images, ready for download to our board or for booting in the QEMU system simulation environment.

Create a project directory

We will create a new project directory where we will run all our PetaLinux projects from:

cd $HOME/Projects
mkdir PetaLinux

Run the BSP install script

To install the board support packages we run the following commands:

cd $HOME/Projects/PetaLinux
petalinux-create -t project -s /home/svenand/Downloads/avnet-digilent-Zedboard-v2013.10-final.bsp

We will use the Avnet-Digilent-ZedBoard-2013.3 BSP.

	zalan November 24, 2014 05:53 PM PST Any one help me with the problem bsp. How can we create custom bsp or from which source i mean. I try petalinux - create -t Projekt -s /home/ngo/Downloads/Avnet-digilent-Zedboard-v2014.2-final.bsp but i got this: No PetaLinux projects found in the BSP /home/ngo/Downloads/Avnet-digilent-Zedboard-v2014.2-final.bsp!


	tanngo November 19, 2014 01:20 AM PST When trying command sudo ./petalinux-v2013.10-final-installer.run /opt/PetaLinux i got "command not found" but i did repair my problem by using the command chmod +x ./petalinux-v2013.10-final-installer.run /opt/PetaLinux ././petalinux-v2013.10-final-installer.run


	Raul September 21, 2014 05:48 PM PDT For CentOS 7 you also need libselinux sudo yum install libselinux.i686


	anjosi August 21, 2014 09:59 AM PDT Hello, THanks for the great tutorial! My Vivado WebPack license file is in xml-format and the PetaLinux license in lic-format is it OK to just merge the lic file into the xml file and get it working?


	Raul August 9, 2014 04:19 PM PDT Just an fyi, CentOS 7 requires `sudo yum install libstdc++.i686` to get the 32 bit libs installed.


	Thorsten June 5, 2014 09:47 PM PDT hi, I have installed all the packages you mention (only ia32-libs is not avail on Ubuntu 14.05) - but when I do petalinux-build I get at the step "expanding stagefs" an error ".../bin/dpkg returned an error code (127)". I have seen in the Xilinx forum that this error seems to be related to the ia32-libs - but as they aren't avail any more I'm stuck with Ubuntu 14. If you have any feedback - let me know ...


	sn June 4, 2014 06:36 PM PDT hi i have installed ise. with its own license but now that i want to install petalinux i must merge the licenses and load the new license again in xlcm. but how can i launch xlcm? when i type cammand "xlcm" it says: cammand not found thanks


	svenand June 3, 2014 09:49 PM PDT I am using Ubuntu 13.10 and Ubuntu 14.04.


	Name May 31, 2014 03:15 PM PDT what Linux distribution are you using?
