ARM嵌入式系统μC/OS-Ⅱ移植分析

Analysis on portingμC/OS-Ⅱbased on ARM embedded system

μC/OS-Ⅱ是专门为嵌入式应用而设计的实时操作系统,移植难度主要体现在所采用的编译器的不同.该文着重介绍了μC/OS-Ⅱ在嵌入式ARM微处理器上的移植方法和过程.采用自由软件Linux下C语言编译器arm-elf-gcc作为开发工具来编译嵌入式操作系统μC/OS-Ⅱ,并利用开源软件SkyEye进行测试,证明其有效性.

μC/OS-Ⅱis the real-time operating system designed for the application of embedded system. The difficulty with porting lies in the different choices of the adopted compilers.This dissertation mainly introduces the porting methods and process ofμC/OS-Ⅱon ARM microprocessor,using arm-elf-gcc of C compiler which belongs to free software Linux as development tools to compile the embedded systemμC/OS -Ⅱ,and using open-source software SkyEye to examine,which proves its availability.
