Interested in learning a little about embedded Linux? Have you worked with Xilinx FPGAs and want to explore some of the software related to their implementation? If you answered yes, then welcome! If you answered no to at least the first question then you should read through anyway, because this is pretty cool stuff.

This GSG will be using the For some more info on MicroBlaze, check out this guide. This guide will walk you through the steps of initial setup for PetaLinux on your Linux machine and the implementation of a pre-built design on the Zybo. By the end of this Instructable, you will be able to begin tinkering with the design from either the hardware description language HDL side, or create custom applications you can run within the Linux system running on your board.

Lets get started! Did you use this instructable in your classroom? Add a Teacher Note to share how you incorporated it into your lesson.

You will need to download the installer for PetaLinux of the same version as the Vivado and SDK installation you should have on your system. Meaning if you have Vivado and SDK The download may take a while. Once the download has completed, make a directory in which you would like the PetaLinux tools to be installed in. From your terminal, change directory cd into the directory the installer was downloaded into likely Downloads and run the installer with a specified path to the directory you just created.

In your terminal, change directory cd into the directory the installer was downloaded into likely Downloads and run the installer with a specified path to the directory you just created. Starting from your home directory, enter the following commands also in screenshot above. This is just one option of installation location. You can install PetaLinux into any typical directory and it will work fine, as long as you have the tools sourced correctly, which we will cover.

As with many software development tools, there are a variety of dependencies that you will need to have in order for PetaLinux to operate.

Many of the packages may already be installed on your computer, but some may not. A full list of the dependencies is included below for Ubuntu. PetaLinux operates using dependencies on bit libraries, so including those specific libraries indicated is required in order for it to operate correctly even if some may seem redundant.

In addition, PetaLinux can utilize a tftp server to streamline the development process, but it is not a requirement for it to function. The specified server package to use is tftpd, however I used tftpd-hpa and would suggest you do the same. If you are unfamiliar with the process of setting it up, you can take a look at this quick Instructable.

Downloading these is the same as any other module that you can get through apt-get, but when you make the following function call or see image above you can simply enter each module's name in the same line with spaces between. The list of dependencies for other Linux distributions can also be found in the PetaLinux documentationstarting on page The PetaLinux tools require you to use 'bash' as your shell rather than 'dash', which is likely your default shell if you're running Ubuntu.I have a Microzed module and Linux machine running Ubuntu I have compiled a Petalinux version for a given hdf file and tested the kernel build using Qemu.

Works perfectly. What I wish to do is run a simple script, mzstartup. UG v In the appropriate Petalinux project director, I have created an app, called mzstartup, created mzstartup. I will be the first to admit that I am not a Linux guru and as such would really appreciate feedback from anyone who has got this to work, as I am sure that I am missing a step in the overall process.

Having spent a couple of evenings on this problem I am keen to resolve it asap, so that I can move forward. I have it working. You should make sure that the paths in your makefile are correct.

Here is my makefile that works. In my case the file iiod. This then becomes part of the the image file. Many thanks for your response to my question - much appreciated.


I did not, however, have the inlude libs. I cleaned my previous Petalinux build using the distclean option and then did a clean rebuild. When I created the application, I did not use the --enable option. From my understanding of the documentation that I managed to find, this is not necessary as one is not wanting to build anything, but rather just copy a script file to the appropriate location, with the appropriate link, hence the install: target must be correct.

Since your setup is working, please could you clarify that this is indeed correct - the application is not enabled in the rootfs config menu. Out of curiosity, I enabled the application and did a clean build. This time I got a build error, which terminated the build process.I am a newbieI found some guys use yocto and others guys use petalinux in this forum, what's the advantages of petalinux or yocto?

As mentioned, Yocto is huge and takes a while to build but you could eliminate what you don't need. It's nice since you can build everything from scratch and there are recipes for most packages you may want. And the other option, which is what I do, is just a homebrew. I wrote a shell script which uses a config file that I manage with menuconfig like the kernel and it know how to build everything things like the FSBL and boot.

Poky takes two or three hours to build Linux depending on your system I built in 20 minutes on an AWS EC2 instancebut it seems somewhat more customizable through the use of bbappend files.

Petalinux will build inside 15 minutes even on my computer at home, but customization is a bear. Petalinux is a good starting point IMHO. Takes forever to download and install, but it's hard to break the instructions in UG There is another option there always is! I use petalinux to configure and build the image and boot files, but all of my applications and libraries are built seperately.

I have a script that compiles and then copies everything into the components directories in petalinux. It works well if you don't need a lot of customization of the kernel, u-boot, etc.

Being experts at it, can you detail which one to choose and why?

PetaLinux is specific to Xilinx, while Yocto is a generic build system for any embedded Linux target. Both also include a distribution, in the context of an embedded Linux distribution. In this context, distribution is mostly referring to the contents of the root file system.

That is, Yocto is the underlying, low-level, high-complexity build system. PetaLinux is the simplified and abstracted version of essentially the same build process. So, for example, you can use Yocto to build the PetaLinux-distribution.

It's just that building it with the PetaLinux-tool is much easier and more streamlined for Xilinx products. Additionally, if somebody is finding it too difficult to customize the PetaLinux-distro using the PetaLinux-tool, then they're probably trying to get at things that the wrapper was designed to abstract! But that's okay. If that happens too much then consider yourself as graduating to the next level of embedded Linux build systems.

And this transition is fully supported by Xilinx. That is, Xilinx provides the appropriate Yocto meta-layers to build the PetaLinux-distro rather than the default Poky distro with Yocto. So the choice of tool is irrelevant with respect to kernel and distro. So which to use? The best person to answer this is yourself!GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together.
