基于TMS320DM6467的嵌入式Linux操作系统移植的研究

摘要

为了应对日益复杂的嵌入式系统应用需求,本文提出在以微处理器TMS320DM6467为核心的视频转码硬件平台VPC6467上,移植嵌入式Linux操作系统的方案.在详细介绍VPC6467硬件平台和Monta Vista Linux特点的基础上,重点论述移植的总体思想和具体方法等,主要包括移植开发环境的搭建、引导程序(Bootloader)的移植与固化、内核镜像的编译和移植、Ramdisk文件系统的制作与移植.移植后的Linux系统操作方便,运行稳定,已作为视频转码应用程序的运行平台环境.%Dealing with the increasingly complicated application demand of embedded system, this paper proposes a scheme for porting embedded Linux operating system on video-transcoding VPC6467 platform with the core of TMS320DM6467 microprocessor. Based on the detailed description of characteristics of VPC6467 platform and Monta Vista Linux, general ideas and specific methods are elaborated, which include the architecture of porting environment, curing of the Bootloader, cross-compiling and porting of kernel image, developing of Ramdisk file system. After the porting, Linux system operates steadily and conveniently, which has been worked as a video-transcoding application platform environment.
