environment targeting the ARM, MIPS, PowerPC and x86 architectures for a variety of - platforms including x86-64 and emulated ones. - You can use components from the the Yocto Project to design, develop, build, debug, simulate, - and test the complete software stack using Linux, the X Window System, GNOME Mobile-based - application frameworks, and Qt frameworks. - </para> - - <para></para> - <para></para> - - <mediaobject> - <imageobject> -

</listitem> - </itemizedlist> - - <para> - The Yocto Project can generate images for many kinds of devices. - However, the standard example machines target QEMU full system emulation for x86, ARM, MIPS, - and PPC-based architectures as well as specific hardware such as the Intel Desktop Board - DH55TC. - Because an image developed with the Yocto Project can boot inside a QEMU emulator, the - development environment works nicely as a test platform for developing embedded software. - </para> - - <para> - Another important Yocto Project feature is the Sato reference User Interface. - This optional GNOME mobile-based UI, which is intended for devices with - resolution but restricted size screens, sits neatly on top of a device using the - GNOME Mobile Stack providing a well-defined user experience. - Implemented in its own layer, it makes it clear to developers how they can implement - their own UIs on top of Yocto Linux. - </para> -</section> -
