28 | The Yocto Project is an open-source collaboration project whose | ||
29 | focus is for developers of embedded Linux systems. | ||
30 | Among other things, the Yocto Project uses an | ||
31 | <ulink url='&YOCTO_DOCS_REF_URL;#build-system-term'>OpenEmbedded build system</ulink>. | ||
32 | The build system, which is based on the OpenEmbedded (OE) project and | ||
33 | uses the | ||
34 | <ulink url='&YOCTO_DOCS_REF_URL;#bitbake-term'>BitBake</ulink> tool, | ||
35 | constructs complete Linux images for architectures based on ARM, MIPS, | ||
36 | PowerPC, x86 and x86-64. | ||
37 | <note> | ||
38 | Historically, the OpenEmbedded build system, which is the | ||
39 | combination of BitBake and OE components, formed a reference | ||
40 | build host that was known as | ||
41 | "<ulink url='&YOCTO_DOCS_REF_URL;#poky'>Poky</ulink>" | ||
42 | (<emphasis>Pah</emphasis>-kee). | ||
43 | The term "Poky", as used throughout the Yocto Project Documentation | ||
44 | set, can have different meanings. | ||
45 | </note> | ||
46 | The Yocto Project provides various ancillary tools for the embedded | ||
47 | developer and also features the Sato reference User Interface, which | ||
48 | is optimized for stylus-driven, low-resolution screens. | ||

59 | Here are some highlights for the Yocto Project: | ||
60 | </para> | ||
61 | |||
62 | <itemizedlist> | ||
63 | <listitem><para> | ||
64 | Provides a recent Linux kernel along with a set of system | ||
65 | commands and libraries suitable for the embedded | ||
66 | environment. | ||
67 | </para></listitem> | ||
68 | <listitem><para> | ||
69 | Makes available system components such as X11, GTK+, Qt, | ||
70 | Clutter, and SDL (among others) so you can create a rich user | ||
71 | experience on devices that have display hardware. | ||
72 | For devices that do not have a display or where you wish to | ||
73 | use alternative UI frameworks, these components need not be | ||
74 | installed. | ||
75 | </para></listitem> | ||
76 | <listitem><para> | ||
77 | Creates a focused and stable core compatible with the | ||
78 | OpenEmbedded project with which you can easily and reliably | ||
79 | build and develop. | ||
80 | </para></listitem> | ||
81 | <listitem><para> | ||
82 | Fully supports a wide range of hardware and device emulation | ||
83 | through the Quick EMUlator (QEMU). | ||
84 | </para></listitem> | ||
85 | <listitem><para> | ||
86 | Provides a layer mechanism that allows you to easily extend | ||
87 | the system, make customizations, and keep them organized. | ||
88 | </para></listitem> | ||
89 | </itemizedlist> | ||
90 | |||
91 | <para> | ||
92 | You can use the Yocto Project to generate images for many kinds | ||
93 | of devices. | ||
94 | As mentioned earlier, the Yocto Project supports creation of | ||
95 | reference images that you can boot within and emulate using QEMU. | ||
96 | The standard example machines target QEMU full-system | ||
97 | emulation for 32-bit and 64-bit variants of x86, ARM, MIPS, and | ||
98 | PowerPC architectures. | ||
99 | Beyond emulation, you can use the layer mechanism to extend | ||
100 | support to just about any platform that Linux can run on and that | ||
101 | a toolchain can target. | ||
102 | </para> | ||
103 | |||
104 | <para> | ||
105 | Another Yocto Project feature is the Sato reference User | ||
106 | Interface. | ||
107 | This optional UI that is based on GTK+ is intended for devices with | ||
108 | restricted screen sizes and is included as part of the | ||
109 | OpenEmbedded Core layer so that developers can test parts of the | ||
110 | software stack. | ||
111 | </para> | ||
112 | |||
113 | <para> | ||
114 | While the Yocto Project does not provide a strict testing framework, | ||
115 | it does provide or generate for you artifacts that let you perform | ||
116 | target-level and emulated testing and debugging. | ||
117 | Additionally, if you are an | ||
118 | <trademark class='trade'>Eclipse</trademark> IDE user, you can | ||
119 | install an Eclipse Yocto Plug-in to allow you to develop within that | ||
120 | familiar environment. | ||
121 | </para> | ||
122 | |||
123 | <para> | ||
124 | By default, using the Yocto Project to build an image creates a Poky | ||
125 | distribution. | ||
126 | However, you can create your own distribution by providing key | ||
127 | <ulink url='&YOCTO_DOCS_REF_URL;#metadata'>Metadata</ulink>. | ||
128 | A good example is Angstrom, which has had a distribution | ||
129 | based on the Yocto Project since its inception. | ||
130 | Other examples include commercial distributions like | ||
131 | <ulink url='https://www.yoctoproject.org/organization/wind-river-systems'>Wind River Linux</ulink>, | ||
132 | <ulink url='https://www.yoctoproject.org/organization/mentor-graphics'>Mentor Embedded Linux</ulink>, | ||
133 | <ulink url='https://www.yoctoproject.org/organization/enea-ab'>ENEA Linux</ulink> | ||
134 | and <ulink url='https://www.yoctoproject.org/ecosystem/member-organizations'>others</ulink>. | ||
135 | See the "<ulink url='&YOCTO_DOCS_DEV_URL;#creating-your-own-distribution'>Creating Your Own Distribution</ulink>" | ||
136 | section in the Yocto Project Development Tasks Manual for more | ||
137 | information. | ||
