devtool devtool is a helper program for adding and modifying recipes in yocto. It is available as part of the yocto build environment either through setting up a full yocto build environment, see Setup and Building or through the Extensible SDK.

Kernel Development Selecting a Kernel To use a different kernel than the default for the machine, set the kernel using PREFERRED_PROVIDER. This can either be set in local.conf for testing/development or in machine/.conf to set the default kernel for that machine.

Recipes Recipes are the fundamental building block of bitbake and therefore of the yocto project. Recipes are stored in layers and contain the instructions on how to build a particular piece of software. There should be a recipe for each 'thing' to be built. Usually this means that one recipe builds one package, but a single recipe can also build multiple packages.

SDK Cross Development SDK The most common way is to cross compile rather than compiling natively. Yocto provides an SDK package that can be built for an image to match possible dependencies in the image. Building the SDK run this command to generate a cross development SDK:

SDKs There are 4 different ways to develop software using the yocto project: * Use a full build, see Getting Started with Yocto and C/C++. * Use an SDK, see SDK. * Use the yocto workflow with an Extensible SDK, see below. * Build natively (on the target), see below. Extensible SDK

Setup and Building Supported Operating Systems The Yocto Project website outlines the following requirements: * At least 90 Gbytes of free disk space, though much more will help to run multiple builds and increase performance by reusing build artifacts. * At least 8 Gbytes of RAM, though a modern modern build host with as much RAM and as many CPU cores as possible is strongly recommended to maximize build performance.
