摘　　要：光纤、无线网络通信的嵌入式操作系统平台与网络应用程序的开发、测试、应用非常广泛,为满足网络交换对软件可靠性的要求,提出一种可靠的板级支持包设计方案,采用处理器8240、伽利略48304交换芯片的最小化系统和VxWorks操作系统内核,基于上电初始化开始的板级支持包设计流程,建立Vxworks系统的板级支持包调试平台,实现板级支持包源代码的设计、移植烧制与测试.实验结果表明通过文件传送协议将修改、编译后的板级支持包成功下载到目标板的闪存中,实现可靠稳定的远程登陆和网络管理.The platform, web application development, testing, application of optical fiber, wireless network communication on embedded operating system have wide applications. In order to meet the requirements of network switching on software reliability requirements, one kind of reliable design of board support package（BSP） was proposed, the minimum system of MPC 8240 and Galileo 48304 based on VxWorks operating system kernel was adopted; based on design process of BSP which started after the power-up initialization, debugging platform of BSP on Vxworks system was established, source code design, transplantation and test of BSP was realized. Experimental results show that the modified compiled BSP is successfully downloaded to the target board flash by file transfer protocol, and the remote login and network management is stable and reliable.
