@xingzhan2012 u盘引导启动系统，备份emmc或tf卡系统到u盘

@macthree 建议全新安装会更好，0303版本是纯净版系统，您也可以下载我们github ubuntu仓库构建纯净版本镜像

@macthree 可以的，有纯净版

coolpi 官方出品

@tonyone0902 如果有环境，建议更新到0315 版本loader。

启动刷机方式都是很灵活可选，用户可以根据自身需求扩展。

Welcome to OpenEmbedded, the build framework for embedded Linux. OpenEmbedded offers a best-in-class cross-compile environment. It allows developers to create a complete Linux Distribution for embedded systems. Some of the OpenEmbedded advantages include:

• adopted as the build system for the Yocto Project in March 2011.

• support for many hardware architectures

• multiple releases for those architectures

• tools for speeding up the process of recreating the base after changes have been made

• easy to customize

• runs on any Linux distribution

• cross-compiles 1000's of packages including GTK+, Qt, the X Windows system, Mono, Java, and about anything else you might ever need
