摘要
论文研究了源代码开放的实时操作系统uC/OS-II在目前流行的嵌入式微控制器ARM7(AT91M40800)上移植的方法。解决了ARM7启动代码中的关键问题,指出了在uC/OS-II的移植过程中的重点和难点问题。该移植在MiceTeckEV40ARM评估板上实现,经该环境的多任务运行结果表明,系统稳定可靠。经测试,其多项实时性指标均达到设计要求。论文对ARM应用的操作系统移植具有普遍的指导意义。
The paper researches the method of porting open source RTOS uC/OS-II to ARM7(AT91M40800),which is a popular microcontroller dedicated to embedded system.It solves the key problems in the bootloader of ARM7,and pre-sents the most important and difficult problems in the course of porting uC/OS-II.A porting has been implemented in on MiceTeck EV40ARM evaluation board,and the system runs steadily and reliably under multitask environment.By testing,the real time parameters have reached the demand of designing.So,the paper has common guidances in porting operator system to ARM.
