Abstract


With the emergence of new technologies , computer and more profound understanding . Computing is getting into the apparatus, the computer system from a variety of physical appearance becomes invisible . The large field of aerospace , into the hands of the PDA are transplanted into a computer system , it is such a system, called embedded systems . Embedded Linux system not only inherited the traditional Linux many advantages , such as ease of development , efficient , powerful , stable , easy to expand , royalty-free , open-source , but also the the embedded transformation of a lot of the original system , so that it better able to adapt to the needs of the embedded application . Various characteristics of embedded devices have limited its device driver must be customized and embedded operating systems and applications completely bound together to form an indivisible whole , so different embedded product development must be designed own device drivers, embedded operating systems provide drivers for example , but the actual operation of the driver must be for specific hardware resource allocation and certain characteristics of the modified or even re-design . This paper focuses on the design and development of the Linux device drivers to do in-depth research and practice . After analyzing the characteristics of the GPRS CF card , this driver layered consider , on the basis of the terminal layer , serial layer , according to their needs on the basis of the serial device driver layer insert a new layer of abstraction driver layer GPRS layer , and for the CF interface , the development of its driver . To solve the competition that may be encountered in the driver development and design , deadlock and bounded buffer problem . At the same time , the project is based on embedded Linux as a means of communication through GPRS driver development , in line with CF interface specification for data processing . GPRS services in Linux implementation is an important part of this paper .
