基于Linux嵌入式系统开发平台的构建及应用

为了能够在硬件基础之上,按照产品要求或者研究需要进行各种嵌入式应用程序的开发,在介绍ARM和Linux特点的基础上,通过宿主机和开发板的对接模式,成功地将嵌入式Linux操作系统移植到32位微处理器S3C2410A上,从而建立所需的嵌入式开发平台。简要讨论几种调试方法,并提出一种整体打包的方法,最后以一个简单的Qtopia菜单程序为例,说明嵌入式应用程序的开发过程。

Establishment and Application of Embedded System Development Platform Based on Linux

As the mass application of embedded products and particular dominance of Linux system, the development and study about embedded systems have become a main topic of discussion. In order to develop various embedded applications based on hardware according to the requirement of products and the need of study, the embedded Linux system is transplanted into the 32 bit micro-processor S3C2410A successfully with the docking mode of the host and development board according to the characters of ARM and Linux, and then the needed embedded development platform is set up. Several debugging methods are discussed and a overall package method is put forward. Taking a Qtopia application as an example, the development process of an embedded application program is depicted.
