Title Embedded Linux System Design Based on PowerPC
Abstract
As embedded systems become more widely used in industrial control,information appliances,electronic products, the study of embedded system has become a hot spot. In many embedded operating systems, Linux has many advantages such as open source code, good portability, rich code resources ,so it gets more and more attention. PowerPC has a wide range of applications in all areas because it has good infrastructure, excellent performance and stability of compatibility.Currently, embedded Linux based on PowerPC has become a stable, proven combination of embedded systems.
This paper focuses on transplanting Linux on PowerPC processors. It introduces the creation of the development environment, U-Boot transplantation, kernel transplantation, customization of packages in roots of the development process. Finally, this paper makes a conclusion and an expectation.
Keywords: PowerPC,embedded Linux,U-Boot,kernel,virtual file system
