说明：  基于 Arm9内核的单片机，由于其低廉的价格与优越的性能，已经被广泛的应用于各种消费类电子产 品中。掌握Arm9 单片机的开发技能已经成为嵌入式系统开发者的迫切要求。但由于市面上的Arm9开发板价格 不菲， 使不少想学习Arm9开发技术的朋友望而却步， 其中有一大部分是各大高校的学生。 本文阐述了改造ipTIME 的IP0422路由器，使其成为VxWorks和Linux的 Arm9开发平台的过程。整个过程简单易行，同时花费在150 元以内，是嵌入式系统开发爱好者不错的选择
(ARM9 core-based microcontroller, because of its low price and superior performance, has been widely used in various consumer electronics products. ARM9 MCU to master the skills development of embedded systems has become an urgent requirement for developers. However, because of the market ARM9 development board expensive, so many want to study the development of technology ARM9 Friend prohibitive, in which one has most of the major colleges and universities are students. This paper describes the transformation of the IP0422 Router ipTIME into VxWorks and Linux development platform of ARM9 process. The whole process is simple, at the same time spent at less than 150 yuan, the development of embedded systems are a good choice enthusiasts)
