The Yocto Project build process supports several types of images to satisfy different needs. When you issue the bitbake command you provide a “top-level” recipe that essentially begins the build for the type of image you want. Building an image without GNU Public License Version 3 (GPLv3) components is only supported for minimal and base images. Furthermore, if you are going to build an image using non-GPLv3 components, you must make the following changes in the local.conf file before using the BitBake command to build the minimal or base image: 1. Comment out the EXTRA_IMAGE_FEATURES line 2. Set INCOMPATIBLE_LICENSE = "GPLv3" From within the poky Git repository, use the following command to list the supported images: $ ls meta*/recipes*/images/*.bb These recipes reside in the meta/recipes-core/images, meta/recipes-extended/images, meta/recipes-graphics/images, and meta/recipes-sato/images directories of your local Yocto Project file structure (Git repository or extracted release tarball). Although the recipe names are somewhat explanatory, here is a list that describes them: core-image-base: A console-only image that fully supports the target device hardware. core-image-core: An X11 image with simple applications such as terminal, editor, and file manager. core-image-minimal: A small image just capable of allowing a device to boot. core-image-minimal-dev: A core-image-minimal image suitable for development work. core-image-minimal-initramfs: A core-image-minimal image that has the Minimal RAM-based Initial Root Filesystem (initramfs) as part of the kernel, which allows the system to find the first “init” program more efficiently. core-image-minimal-mtdutils: A core-image-minimal image that has support for the Minimal MTD Utilities, which let the user interact with the MTD subsystem in the kernel to perform operations on flash devices. core-image-basic: A foundational basic image without support for X that can be reasonably used for customization. core-image-lsb: A core-image-basic image suitable for implementations that conform to Linux Standard Base (LSB). core-image-lsb-dev: A core-image-lsb image that is suitable for development work. core-image-lsb-sdk: A core-image-lsb that includes everything in meta-toolchain but also includes development headers and libraries to form a complete standalone SDK. See the External Development Using the Poky SDK section for more information. core-image-clutter: An image with support for the Open GL-based toolkit Clutter, which enables development of rich and animated graphical user interfaces. core-image-sato: An image with Sato support, a mobile environment and visual style that works well with mobile devices. The image supports X11 with a Sato theme and Pimlico applications and also contains terminal, editor, and file manager. core-image-sato-dev: A core-image-sato image suitable for development that also includes a native toolchain and libraries needed to build applications on the device itself. The image also includes testing and profiling tools as well as debug symbols. This image was formerly core-image-sdk. core-image-sato-sdk: A core-image-sato image that includes everything in meta-toolchain. The image also includes development headers and libraries to form a complete standalone SDK. See the External Development Using the Poky SDK section for more information. From the Yocto Project release 1.1 onwards, -live and -directdisk images have been replaced by a "live" option in IMAGE_FSTYPES that will work with any image to produce an image file that can be copied directly to a CD or USB device and run as is. To build a live image, simply add "live" to IMAGE_FSTYPES within the local.conf file or wherever appropriate and then build the desired image as normal.
