Abstract


Mainstream of domestic electrical and mechanical equipment controller PLC, with the development of computer technology , based on the rapid growth of embedded systems products in this area , embedded systems and their applications has become the hotspot of current research and applications . Microkernel embedded systems , streamline the system , high real-time , specific and strong features , make it very suitable for mechanical and electrical control systems . Electromechanical control systems embedded systems reliability, size , power consumption , cost-effective compared to traditional control system has obvious advantages . Therefore , the design and development of embedded controllers will become a trend in the field of electro-mechanical control . The embedded controller consists of two parts of the hardware and software components . The former is the physical basis for the entire system , which provides a software operating platform and communication ( including human-computer interaction ) interfaces , the embedded processor core ; latter the actual operation of the control system , the core of the operating system running application software . A major work in the design and development of an embedded controller is the operating system ported to an embedded processor - based hardware platform . In this paper, the core of the work carried out analysis of research and application of a wide range of Linux 2.6 kernel ported to ARM-based hardware platform . In this paper, several core technology platform porting to arm linux kernel related discussions. First discusses the operating system migration theory , and analysis of the main advantages of portability of the Linux operating system are summarized . Then describes the architecture of the arm , the arm platform linux kernel and transplant some structure in-depth analysis of research on the important bootloader transplantation in the realization of the principle and transplant method and existing hardware platform bootloader the transplantation and kernel transplant . Finally, detailed analysis of the embedded linux boot and start the process , analysis and the relevant code .
