嵌入式操作系统μClinux移植研究

Transplant Research of Embedded Operating System μClinux

为开发一个稳定性好、适应性强和安全性高的适合多嵌入式操作系统平台的嵌入式Web服务器,搭建μClinux移植需要的开发配置环境和设计移植的系统流程,讨论了移植μClinux需解决的如交叉编译环境的建立、μClinux的内核加载方式、改写编译blob.bin和烧blob等一些关键性技术问题,对μClinux移植做了恰当的裁减和分析工作以适合在设计的平台上的移植。并对移植μClinux需要的烧bootloader到Flash、烧μClinux内核文件到Flash、烧romf只读文件系统到Flash的分析研究及根文件系统的烧到Flash进行了详细过程描述。

To develop a stable, strongly adaptive and highly security embedded Web server for adapting well to multi-platform embedded operating systems, build development configuration environment and system process of transplant μClinux,it discusses some key techuical problems which are cross-compilation environment establishment, p.Clinux kernel loading method, rewriting and compiling of blob. bin and burning blob, does appropriate cuts and analysis for transplant μClinux in order to suit for the transplant in design of the plat- form, and describes the needs of transplant μClinux which are burning boofloader to Flash, burning kernel file to Flash 0 burning readonly romfs file system to Flash and root file system burning to Flash in detail.
