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 transplantation.
