摘要
以基于S3c2410处理器和Linux2.6内核组成的嵌入式系统为研究对象,通过对其热插拔支持和文件系统自动加载的系统研究,主要采用修改驱动程序和shell脚本编程完成对USB闪存的热插拔事件的响应并实现文件的自动挂载,从而使得基于此种嵌入式系统的注塑机控制器存储量得到扩展,并希望以此为契机,为更好的实现其他移动存储介质(如SD卡等)的存储扩展提供成熟、易行的技术基础。
This paper provides a method of memory extension by a usb flash which was inserted to an embedded system based on Linux 2.6 operating system and S3C2410 through a systematic study on the hotplug event support. The method mainly uses a modification of device drive and a bash script to support the hotplug event and to automatically mount the file system on the operating system in order to extend the memory size of a controller of a injection molding machine. It can be considered as a sophisticated and practical tech basis to achieve the memory extension by other mobile media of memory, such as sd card,etc.
