摘要
为了将嵌入式实时操作系统eCos,在以ARM920T处理器S3C2410为核心的开发板上运行,对eCos的一般性移植方法进行了研究,提出了将eCos向目标板移植的具体方法。在将硬件抽象层HAL针对目标板做了修改和移植后,生成最小配置的redboot镜像,用以在目标板上引导eCos。在此基础上针对目标板增加eCos的配置选项和包,结合C代码和eCos库文件编写了eCos应用程序,结果表明eCos以及应用程序在目标板可以正常运行。
To run embedded system on the developing real time operating board based on ARM920T processor S3C2410, the general methods of system transplantation were studied. The author presented a concrete procedure of transplanting eCos to target board. After modifying and transplanting HAL for the target board, a redboot image with minimum configuration was built to guide eCos. Then more configurations and packages were added to the target board as well as an eCos application program was compiled. The result shows that eCos and its application program can run normally on the target board.
