基于S3C2440的嵌入式LINUX操作系统内核研究

中文摘要

嵌入式Linux是以Linux为基础的嵌入式操作系统，可应用于多种硬件平台，是一个和Unix相似、以内核为基础的、具有完全的内存访问控制，支持大量硬件等特性的一种通用操作系统。它能够适应对工业控制领域高实时性的要求，被广泛应用在移动电话、个人数字助理、媒体播放器、消费性电子产品以及航空航天等领域中。

本课题是以GT2440开发板为平台来研究Linux操作系统的内核，GT2440采用高主频高性能的SamsungS3C2440A处理器作为主控芯片，接口资源丰富，具有通用性。主要完成Nand Flash驱动、LCD驱动、CS8900A网卡驱动、UDA1341声卡驱动、触摸屏驱动、SD卡驱动、RTC驱动和USB驱动等移植实现。最后把移植的内核文件下载到GT2440开发板进行测试，测试结果验证了内核移植的正确性。

Study of Embedded Linux Operating System Kernel Based on S3C2440

Abstract

Embedded Linux is a embedded operating system based on Linux, which can be applied to a variety of hardware platforms, with full memory access control, supporting for a lot of hardware features. It can adapt to real-time requirements on the field of industrial control, it is widely used in mobile phones, personal digital assistants, media players, consumer electronics, and aerospace and other fields.

The kernel of the Linux operating system is studied based on the GT2440 in the topic, the GT2440 uses high frequency and high-performance SamsungS3C2440A processor as the master chip, whose interface is rich in resources and versatile. Primarily the transplanting of NandFlash drive,LCD driver,CS8900A LAN Driver,UDA1341 sound card driver, touch screen driver, SD card driver, RTC driver and USB driver are finished. Finally, the kernel file transplanted is downloaded to the GT2440 development board for testing, and the test results verify the correctness of the kernel transplant
