摘要
随着嵌入式操作系统VxWorks的广泛应用,如何让VxWorks支持各种硬件平台成了急需解决的问题。首先介绍大幅面扫描仪的发展趋势以及嵌入式操作系统VxWorks的优势。然后通过分析VxWorks的SENS协议栈;VxWorks下END网络驱动程序的结构;S3C2440A板载DM9000网卡的硬件特性和操作特点,实现基于VxWorks的DM9000 END驱动程序。最后修改相应bsp,使S3C2440A可以跨平台通信。
With the extensive application of VxWorks, how to make VxWorks support various hardware platforms is an urgent problem must to be solved. Firstly this article introduces the development direction of Large Format Scanner and the superiority of VxWorks. Then, analyzes the SENS protocol in VxWorks stressed;the frame of END driver base on VxWorks; the peculiarity of hardware and the trait of operate which DM9000 network card has, then the end driver of DM9000 based on VxWorks achieved. Finally,modified the bsp,ensure the S3C2440A can communicate between different operating system.
