Overview
[edit]OpenEmbedded is a software framework to create Linux distributions aimed for, but not restricted to, embedded devices. The Build system is based on BitBake reciepes[2], wich behave similar to Gentoo's ebuilds.
Reciepes in the old OpenEmbedded-Classic where all found in one place, in the new OpenEmbedded-Core the structure has changed into meta layers[3][4] to make it easier to add custom recipes.
OpenEmbedded can be installed and automatically updated via Git[2]
OpenEmbedded-Classic
[edit]The OpenEmbedded Project (OE for short, but mostly called OE-dev, following the name of the mailing list[5]) was created by Chris Larson, Michael Lauer, and Holger Schurig, merging the achievements of OpenZaurus with contributions from projects like Familiar Linux and OpenSIMpad into a common codebase. OpenEmbedded superseded these projects and was used to build any of them from the same code base. Stable maintenance builds exist for the old OpenEmbedded-Classic[6], altough the most development is, or will be based, on the new OpenEmbedded-Core in the future.
OpenEmbedded-Core
[edit]![[icon]](/wiki/File:Wiki_letter_w_cropped.svg?lang=en){kind=small} | This section needs expansion. You can help by adding to it. (aug 2011) |
The OpenEmbedded-Core Project (OE-Core for short) resulted from the merge of the Yocto Project™ with OpenEmbedded.[7] This is the most recent version of OpenEmbedded and many of the OE-dev recipes are available in OE-Core. Newer versions of package recipes may only get ported for OpenEmbedded-Core
Layer organisation in OpenEmbedded-Core
[edit]OpenEmbedded-Core has adapted this layered structure in the merge with Yocto and new layer entries were added over time.[3][4]
The Layers represent a structure which is only of declarative nature. The specific entries are more strict in the scope of deciding which entry provides wich packages.
Developer layer
[edit]The user defined layer for custom Bitbake recipes. Embedded system software developers would place their recipe here if the software would not fit the commercial or base layer.
Commercial layer
[edit]Packages, plugins and configurations from open source vendors go in this layer.
UI-specific layer
[edit]Layers currently present within the meta-openembedded layer:
- meta-efl (Enlightenment window manager)
- meta-gnome (GNOME window manager)
- meta-gpe (GPE window manager)
- meta-xfce (Xfce window manager)
Hardware-Specific layer
[edit]- meta-efikamx (Efika devices)
- meta-intel (Intel embedded devices)
- meta-nslu2 (NSLU2 devices)
- meta-openpandora (Openpandora device layer)
- meta-smartphone (various smartphone devices)
- meta-texasinstruments (Texas Instruments devices)
- meta-xilinx (Xilinx devices)
- (Others)
Yocto layer
[edit]- meta-yocto (Yocto Project™ layer [7][3])
OpenEmbedded-Core layer
[edit]- openembedded-core
- meta-openembedded
Distributions supported by OpenEmbedded
[edit]In OpenEmbedded the configurations from Base- to the UI-Layer can be supplemented by various Linux distributions. The following list is available for OpenEmbedded.
Supported hardware
[edit]See [10] for a partial list of supported devices.
Boards and processors
[edit]The BeagleBoard and Gumstix[11][12] boards from Texas Instruments and several I.MX devices (for example the I.MX28 series[13]) from Freescale are supported.[citation needed]
Other well known boards like the PandaBoard are also supported [14][15] along with other hardware.
Some devices of the IBM PowerPC series are supported by OpenEmbedded [16]
Smartphones
[edit]Smartphones like the Nokia N800 and Neo FreeRunner are supported.
Porting OpenEmbedded to new hardware
[edit]The constellation of OpenEmbedded, especially the open design, allows it to get OpenEmbedded to adapt new hardware fairly easy.[17][18]
