Linux Embedded Systems Research In The Field Of Industrial Control And Achieve

Along with the development of the information, the network and the intelligence, the embedded technology is improved a lot. Because of its stability, open-source, easy-porting and other strongpoint, linux is widely used in embedded field and has huge potation and value in commerce. Because there are many embedded processors, porting linux to a processor is the first step of using linux in embedded area.Recently, along with the fast development of computer and communications technology, especially rapid popularization of Internet and syncretism acceleration of 3C(Computer Communication &Consume Electric), micromation and specialization become the main developing trend, at the same time, embedded products turn into the mainstream of information industry. System porting to the target platform is the main factor which affects the process of embedded-systems development.Among the main embedded processors, ARM is the main stream. So after researching and testing on the linux, the author introduces several key technology about linux porting. First, the author introduces the ARM architecture in detail to make the readers have deep impression. Then, the author explains the concept, the characteristic and the functions of bootloader and how to port a bootloader. And the author modifies the important data structures of the linux kernel related to ARM and the interrupt and memory management. Next, the author introduces the types of the file system and how to build a linux file system. At last, the Linux will be in Human Machine Interface field. It is the first Linux embedded system which is used in Human Machine Interface field. I believe that this success will improve the application of Linux system in industry area.AS the above issues, this thesis makes a detailed analysis at theories and techniques for porting Linux to ARM embedded system. This thesis also explores and implemented the porting of Bootloader, file system and other parts.
