摘　　要：为实现嵌入式网络和多媒体应用的通用开发平台,提出了一种基于ColdFire5470和Linux的嵌入式平台设计方案。详细设计了开发平台硬件系统的各电路接口模块,完成了基于硬件平台的Linux+U-Boot移植。在此基础上,为平台设计了用于功能模块检测的片上诊断系统,构建了完整的开发平台系统。最后设计了测试软件,并通过该软件完成了针对系统功能和应用完整性的测试工作。该开发平台为嵌入式应用系统的进一步开发和通信系统的算法研究工作提供了可靠的支持。To realize the general development platform for embedded network and multimedia application,a construction of the whole embedded platform based on ColdFire5470 and Linux is proposed. The modules of hardware system of the platform are designed in detail,and the porting of Linux and U-Boot based on the hardware platform is finished. And then an on-chip diagnosis system is designed for the platform. Finally,the test program is designed,and the function and application test is taken for the system. This platform can only is used for algorithm research on communication system,but also is useful for further application development of embedded system.
