uClinux在Nios II嵌入式平台上的移植研究

Research on transplant of uClinux in Nios II microprocessor

结合2.6内核版本的uClinux,分析了移植uClinux操作系统的关键技术,在介绍NiosII嵌入式平台后,就操作系统内核的移植、initramfs文件系统、开发环境、引导程序、操作系统映像的构建等方面进行研究分析,并给出了实现方法,该移植已在NiosII应用开发板上实现。

This article analyses some key techniques of transplanting uClinux by using the latest version 2.6. After the brief introduction of Nios Ⅱ microprocessor, this article firstly researches on the transplant of uClinux operating system, the developing environment, the bootloader, the initramfs file system, and the design of kernel image. Then, it listed the ways of the implementing this transplant which has already been implemented on the Nios II development board.
