New Horizons









Welcome to my blog

My name is Sven Andersson and I
work as a consultant in embedded
system design, implemented in ASIC
and FPGA.
In my spare time I write this blog
and I hope it will inspire others to
learn more about this fantastic field.
I live in Stockholm Sweden and have

FPGA design from scratch. Part 73

Installing PetaLinux SDK

We will follow the procedure described in the document PetaLinux SDK Installation Guide.

Downloading the software

As promised I received three emails from PetaLogix with download links for the following items:

  • The license file
  • PetaLinux SDK
  • BSP file for Avnet Spartan-6 LX9 MicroBoard

Here are the files after downloading.




Extract the PetaLinux package

Move the tar file to the installation directory.

--> cd /opt/home/svan/PetaLinux

--> mv ../Downloads/PetaLinux/petalinux-v2.1-final-full.tar.gz .

Extract the compressed PetaLinux package by running the following command:

-> tar zxf petalinux-v2.1-final-full.tar.gz


Install license file

Copy the license file (PetaLogix.lic) to the directory: $HOME/.PetaLogix

Setup PetaLinux working environment

Goto to the PetaLinux root directory:

--> cd $HOME/PetaLinux/petalinux-v2.1-final-full

Source the PetaLinux setup script to complete the installation and accept the license agreements:

--> source settings.sh



Missing packages

In Debian 6.03 the following packages were missing and had to be installed:

  • libghz6-zlib-dev
  • lib32ncurses5-dev
  • dos2unix


Verify the environment




PetaLinux BSP installation procedure

PetaLinux includes reference designs for us to 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.

Goto to the PetaLinux root directory:

--> cd $HOME/PetaLinux/petalinux-v2.1-final-full

Run the following script:

--> petalinux-install-bsp ../BSP/Avnet-LX9-Microboard-v2.1-final.bsp




Here is the final result:




Congratulations! We have completed the PetaLinux SDK installation.


Getting started with PetaLinux SDK

We will follow the procedures in the document Getting Started with PetaLinux SDK.

Test a pre-built PetaLinux image on hardware

PetaLinux BSPs include pre-built FPGA bitstreams for each reference design, allowing us to quickly boot PetaLinux on our hardware. Here are the steps to test a pre-built PetaLinux image with hardware:

  1. Choose the correct board for the reference design (Avnet-LX9-Microboard-MMU-tiny-13.1)
  2. Connect the JTAG port on the board with JTAG cable to our workstation.
  3. Connect the UART USB port to our workstation
  4. Connect the ethernet port on the board to the local network via a network switch
  5. Open a console (GTKterm) on our workstation with the baud rate set to 115200
  6. Source the Xilinx settings file 
  7. Source the PetaLinux settings file
  8. Run the petalinux-boot-prebuilt command



Be patient, it can take more than five minutes to complete. Wait until we see the shell prompt again on the command console.


MicroBoard console display

If everything works we will first see the following display on the console:




And then this one.




Logging in

Type user name root and password root to log into the PetaLinux system.

Directory structure

This is what the first directory layer looks like.



/tmp is a writable temporary file system where we can create and edit files.

The /dev contains entries for various devices in the system. /dev/console is the main console. We can try to copy a file to /dev/console  to see what happens. The file content will be displayed on the console screen.




Some useful commands

The file /proc/cpuinfo contains details about the CPU.

--> cat /proc/cpuinfo



The file /proc/interrupts gives interrupt information.

--> cat /proc/interrupts



Accessing the web server

Open a web browser and type http://192.168.1.120

Use this command to find the IP address: ifconfig




Here is the web browser display. We are connected to the web server running on our MicroBoard. Magical!




Using the web server

The web server is not there only for fun. It can be used to control and administrate the embedded system from a standard web browser. Here are some examples:

It can be used for upgrading the firmware in the system.



It can be used for displaying the system log.




The web server is built using a tool from WorkWare Systems called µWeb.
