本文UCOS是根据我学习ARM开发以来的一些经验总结，以自己设计的S3C44B0X板为例，给出入门上手的最基础知识。有些东西只是个人的主观认为，不一定准确，算作抛砖引玉吧，欢迎大家指正！-this paper is based on my study of the ARM since some experience to design its own board of S3C44B0X example, the entry is easily the most basic knowledge. Some things are just personal subjective view, is not necessarily accurate, it counted as something, we welcome correct!
