Petalinux u boot

I'm trying to customize u-boot using Petalinux One of the customizations that I am making is that I would like to remove the boot delay and set it to 0. View solution in original post. I think you will find that either this doesn't get propagated to the u-boot environment part of one of the autogenerated files I was able to change the bootdelay environment variable using the u-boot terminal and save the environment, but I'm not able to change the default which appears to be set here:.

I'm guessing that the 4 second boot delay is getting picked up in the generated u-boot config file but I just don't know how to override it.

Note: Some things cannot be done via configuration. In order to override those you need to modify platform-top. Seems unrelated to u-boot. Something is wrong your "peekpoke64". Remove it via petalinux-config -c rootfs and try building again. The second issue was what Mark had originally stated that the saved environment was being picked up as well. When I used your fix and reset the environment to default it picked up the proper bootdelay. Does this make any difference?

It should be something like this below. When I did the same before, with petalinux Now it doesn't. Yes in For more details refer Default setting is bitbake, not devtool. After changing to devtool, the bahaviour of whole process is slightly different. I found it inconvenient, especially due to different file naming scheme in meta-user. For u-boot and kernel menuconfigs backend default is devtool eventhough you are not swtiching to devtool in Yocto settings.

Yes I can reproduce the issue using u-boot, looks like it doesn't work in petalinux devtool. I have filed a CR and we will create an AR on this one. Sign In Help. Turn on suggestions.

I'm unclear on how petalinux decides where to store the kernel image and how it is linked. I seems like petalinux will just add the image file starting from the third parition address no matter what in this case 0x1c For example, I would like to add my kernel image to adddress 0x but I get the following error:. Taking a look at the bootgen. It seems like petalinux will just add the image file to the third partition regardless of various settings.

Is there some sort of label I could use to specifiy the partition I would like petalinux to add the image. Specifically I want to target this parition:.

How can I specifiy the exact offset of the image in petalinux-config? I believe I should be able to edit this file and run bootgen myself but was wondering how this could be done through the petalinux sdk. I'm still unclear why petalinux automatically assigns the image to the thrid partition regardless of the address offset. I can change it from 0x1c to 0x and it will still attempt to assign it there. What is the mechanism the decides the third parition is where the image must go?

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. To change this, just enter the following command, which will set your default from 'dash' to 'bash'.GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together.

This project includes the Digilent-apps repository, a set of linux libraries, utilities and demos that are packaged as Petalinux apps so they can easily be included with Petalinux projects. This guide will walk you through some basic steps to get you booted into Linux and rebuild the Petalinux project. After completing it, you should refer to the Petalinux Reference Guide UG from Xilinx to learn how to do more useful things with the Petalinux toolset.

Also, refer to the Known Issues section above for a list of problems you may encounter and work arounds. This guide assumes you are using Ubuntu Digilent highly recommends using Ubuntu Digilent has put together this quick installation guide to make the petalinux installation process more convenient.

Note it is only tested on Ubuntu Next, install and configure the tftp server this can be skipped if you are not interested in booting via TFTP :.

Finally, download the petalinux installer from Xilinx and run the following do not run as root :. Whenever you want to run any petalinux commands, you will need to first start by opening a new terminal and "sourcing" the Petalinux environment settings:.

There are two ways to obtain the project. If you plan on version controlling your project you should clone this repository using the following:. If you have obtained the project source directly from github, then you should simply cd into the Petalinux project directory.

If you have downloaded the. This will create a new petalinux project in your current working directory, which you should then cd into. Follow the same steps as done with the pre-built files, except use the BOOT. BIN and image. This project is initially configured to have the root file system rootfs existing in RAM. This configuration is referred to as "initramfs". This may or may not be desirable functionality.

Another side affect of initramfs is that if the root filesystem becomes too large which is common if you add many features with "petalinux-config -c rootfs then the system may experience poor performance due to less available system memory.GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together.

Latest commit a7 Apr 1, The development of U-Boot is closely related to Linux: some parts of the source code originate in the Linux source tree, we have some header files in common, and special provision has been made to support booting of Linux images. Some attention has been paid to make this software easily configurable and extendable.

For instance, all monitor commands are implemented with the same call interface, so that it's very easy to add new commands. Also, instead of permanently adding rarely used code for instance hardware test utilities to the monitor, you can load and run it dynamically. In fact, many of them are used in production systems. There is also an archive of previous traffic on the mailing list - please search the archive before asking FAQ's.

The spelling "U-Boot" shall be used in all written text documentation, comments in source files etc. File names etc. Regular releases are identified by names consisting of the calendar year and month of the release date. Additional fields if present indicate release candidates or bug fix releases in "stable" maintenance trees. Examples: U-Boot v Previously, all configuration was done by hand, which involved creating symbolic links and editing configuration files manually.

More recently, U-Boot has added the Kbuild infrastructure used by the Linux kernel, allowing you to use the "make menuconfig" command to configure your build. Sandbox Environment: U-Boot can be built natively to run on a Linux host using the 'sandbox' board. This allows feature development which is not board- or architecture- specific to be undertaken on a native platform.

The sandbox is also used to run some of U-Boot's tests. Board Initialisation Flow: This is the intended start-up flow for boards. At present, SPL mostly uses a separate code path, but the function names and roles of each function are the same.

Some boards or architectures may not conform to this. Execution typically starts with an architecture-specific and possibly CPU-specific start. S and so on.

From there, three functions are called; the purpose and limitations of each of these functions are described below. Many of the options are named exactly as the corresponding Linux kernel configuration options. The intention is to make it easier to build a config tool - later. This is necessary for ePAPR compliance, among other possible reasons.It covers the following:.
