| Abstract: | The way to develop device drivers under the embedded Linux operating system is brought forward. The general module framework and the particular development process of the device drivers under embedded Linux are expatiated. The relationship between Linux device drivers and kernel is made clear, the common characters of embedded Linux device drivers is summarized. The concept of modularization of Linux device drivers is illuminated. Further more, the two key functions of modularized device drivers is analyzed, namely init module Oand cleanup_module O. How to design and program the modularized device drivers under embedded Linux by explaining an example driver is discussed and some pivotal codes are made clear. In the end, the core idea on the development of device drivers under embedded Linux is concluded. |
