ARM9-Based Embedded Linux Platform For Applied Research

With the computer software and hardware technology, network application technology in particular, the continuing popularity of embedded systems technology and society in various fields has become increasingly extensive application. At present, embedded systems technology and application of IT industry has now become the most popular areas of study. ARM with its high-performance low-power characteristics has become the most widely used 32-bit embedded processor, also embedded Linux, with its powerful, free, as well as the development of resource-rich, and so take advantage of the embedded operating system dominance, so Research on embedded systems theory and its practical application has a good sense of reality.Embedded system is embedded application software, embedded operating systems, embedded hardware platforms (including processors and peripherals) pose. In the paper, the choice of ARM processor S3C2410 system as the embedded processor, Linux as an embedded operating system. On the basis, the construction of embedded systems with a certain degree of versatility and exemplary, and some of its research and development.The main thesis of research content includes:analysis of the embedded system hardware platform; software development platform to build, including:U-boot process work and to introduce specific transplant, Linux kernel transplant strategy and the specific configuration, as well as the production file system; In the final set of embedded system platforms, the realization of LCD driver to complete the audio driver, the current popular digital products, the transfer of MP3 and video applications, user interface MiniGUI, and the use of MiniGUI realized static and dynamic display pictures.The images show that the combination of Vidcat applications to achieve a collection of video images.The results show that:this study was able to develop on-board ARM9 and stable operation of embedded development and research has a practical and useful.
