类似与windriver linux的一个开源东东

这个网站是这么介绍的:

Instead of trying to create a single, static firmware, OpenWrt provides a fully writable filesystem with package management. This frees you from the application selection and configuration provided by the vendor and allows you to customize an embedded device through the use of packages to suit any application. For developers, OpenWrt is the framework to build an application without having to build a complete firmware around it. For users, this means and gives the ability for full customization, to use an embedded device in ways never envisioned.

• Free and open-source. The project is entirely free and open-source, licensed under the GPL. The project intend to always be hosted at an easily accessible site, full source code readily available and easily built.
• Easy and free access. The project will always be open to new contributors and have a low barrier for participation. Anyone shall be able to contribute. We, the curerent developers, actively grant write access to anyone interested in having it. We believe people are responsible when given responsibility. Just ask and you will be able to acquire the access rights you need.
• Community driven. This is not about 'us' offering 'you' something, it is about everyone coming together to work and collaborate towards a common goal.

It has for a long time been established that OpenWrt is the best firmware solution in its class. It far exceeds other embedded solutions in performance, stability, extensibility, robustness, and design. It is the clear-cut goal of the OpenWrt developers to continue and expand development, and ensure that OpenWrt is frontrunner as framework for innovation and ingenuitive solutions.

What is it not?

OpenWrt is not intended as being a ready-made distribution you directly can load onto an embedded device. Instead, the framework allows you to create a firmware tailored to your own particular needs.

Although there are several UI projects available to cover common use cases, OpenWrt is not an end user firmware. More advanced tasks require command line operation and basic knowledge about operating a Linux based system.
