Transplantation Research and Implementation of Embedded Linux System Based on S3C2440

An embedded system under the development of the microprocessor is widely applied in the world. The basis of further research and development and application is the question of how to build a small, real-time, good performance of embedded operating system. This research paper describes the methods and process of latest u-boot-2015.07, latest stable version of the linux-4.2.1 kernel, yaffs2 file system and the root file system transplant to the target board based on S3C2440 processor. The results prove that post-transplant Linux runs well on the target board. Embedded system migration not only familiarizes us with in-depth Bootloader, Linux kernel, file system and other software, but also get to know the various hardware resources of the target board.
