Build Description Factory The official, stable image available from Gumstix. This image is the best choice for new users who want to get started. Weekly Master A weekly build of the master branch. This branch is considered stable, and may include stable features not yet available in the factory image release. Development A weekly build of the development branch. This branch contains bleeding edge features, which may or may not be stable. This image is intended for experienced users.
Software Downloads Yocto Project. These Poky 1.8 (Fido) and Poky 2.1 (Krogoth) Images for Gumstix platforms are built using tools from the Yocto project. Source code can be downloaded from Gumstix' GitHub. To make a microSD card for your board, you will need the following files: Name Function MLO A second-stage bootloader binary image for COMs RootFS A root file system Das U-Boot A bootloader binary image MD5 MD5sum to verify file download More Information About Yocto Project Images These images are built using the.
To recreate these builds, follow the instructions. Gumstix also uses a buildbot to create these images. You can check the build status. Gumstix platforms support Ubuntu 15.04 (Vivid Vervet).
Source code can be downloaded from. There are two ways to download Ubuntu for your Gumstix system. The first is downloading an image file that can be directly copied onto a microSD card using the dd command; this is the easiest way to get started. The image files can be found on the individual product pages software tab. Users can also download all necessary files separately and install them on a microSD card, following the instructions in the.
Also from the Gumstix Lab: Ubuntu Snappy Core images supporting Gumstix products can be found. Angstrom images are for Verdex Pro COMs only, and can be downloaded from. Bitbake and Yocto Project Gumstix publishes several different pre-built images as well as kernel and bootloader binaries. It is also possible to build these binaries using bitbake by setting up the build environment.
Developers who are familiar with the OpenEmbedded build system will find a lot in common between the Yocto Project and OpenEmbedded, because the Yocto Project uses some of OpenEmbedded elements while improving build environment in multiple aspects. The Yocto Project build system consists of a collection of 'recipes'. These recipes contain the source URL of the package, dependencies, and compile and install options. It uses the information in these recipes to track dependencies, cross-compile the package, and create binary packages. It will also create complete images including boot loaders, kernel, and root file system. As a first step the framework will build a cross-compiler toolchain for the target platform. For more detailed information, read the and user guides.
Yocto Project is a flexible, capable build tool. There is, however, a lot to know in order to fully exploit its power. After setting up your build environment, your directory structure should look like this: poky -bitbake -documentation -meta - meta-gumstix - meta-gumstix-extras -meta-hob -meta-openembedded -meta-skeleton -meta-ti -meta-yocto -meta-yocto-bsp -oe-init-build-env `-scripts The two bold faced directories are Gumstix Board Specific Layers (Gumstix BSP). These two are the places to look at if you would like to add/remove recipes (and ultimately packages in the root file system). Other layers are the dependencies of Gumstix BSP. Additionally, you can get the source code from their Github repositories: and. Meta-gumstix This directory contains recipes that either add Gumstix specific features or override the standard OpenEmbedded recipes. This is where the Gumstix specific customizations reside.
Bitbake will give preference to recipes that it finds the Gumstix BSP over recipes contained in other meta layers. Meta-gumstix-extras This directory completes the meta-gumstix layer with the recipes to build the custom Gumstix Linux distributions.
For the available types of build targets, please see this. For the complete explanation of each directory, take a look at the Appendix A. Reference: Directory Structure in the Yocto Project Reference Manual. These instructions are for creating an build system for the Gumstix COMs.
Much like Gentoo Ebuilds on x86, the Yocto Project is a software framework to create Linux distributions. It downloads the source code and cross compiles it for you as needed. The Yocto Project builds everything from scratch including the cross compilation toolchain. This section will show you how to set up the environment on your Linux development system. Gumstix offers several pre-built images for download:. The console image is a lightweight root file system image providing only a command-line interface with out any GUI support. It is similar to server versions offered by several other Linux distributions and can be a great building block for making a custom image.
The palmtop image offers a handheld-like environment with a lightweight GUI designed for small, touchscreen displays. The desktop image is a fully-fledged Linux desktop environment complete with web browsers, media players and office utilities. As so many applications are built-in, this image is too large for the NAND flash and must be loaded onto a bootable microSD or NFS mount. Bitbake Targets.

This page explains how to build Android from source or to update an. If you just want to, you may prefer to use. All the source code is freely available for download, customization, and improvement. This section explains how to set up a development machine to build all the required components from source. These instructions have been tested on Ubuntu Maverick (10.10) 32 and 64 bit machines; as a rough estimate, this process requires 10GB of hard drive space and takes 4 hours (30 minutes of setup, 1.5 hours to download code, and 2 hours to build) on a moderate development machine.
Users with existing Android source can.
