Research On Porting Of ARMLinux And Applications In ARMLinux System Based On Embedded Home Gateway

In digital technology and modern society that network technology develop rapidly, family long-range to manage and control, informationization of household appliances with networked to become the trend of the times.The connections of the home and Internet need a nerve center to be the family network central controller in family's information-based network technology system research and product development , or called " the home gateway ". home gateway externally link with Internet, internal wireless LAN join household appliances and other power consuming facility into an organic whole inside house, have offered network platform and open automatic system directed against the consumption electronic product, can realize the intellectual house , various kinds of functions and services of the electrical home appliances network on this basis.The thesis has introduced embedded system and the definition of the embedded home gateway , development overview ,etc. at first, then provide the software and hardware structure chart of the gateway. Probe into embedded Linux operating system thoroughly , has analysed the boot course of Linux especially and bootloader code, put up the development environment of embedded Linux , has laid a solid foundation for the work of transplantation for the future.have chosen ARMLinux operating system as transplanting to the target based on the analysis and the study about Software and hardware structure of the whole system., and has succeeded in transplanting it to the platform of hardware taking S3C2410 microprocessor as the core.Have transplanted and tested the r/w YAFFS file system to NAND Flash memory , build CRAMFS +YAFFS multi File system on the basis of this. Have solved problems about the dynamic access of the data and systematic issue of stability in the system.Thesis also related to ARMLinux program development and debug method. Confirmed the B/S mode based on the requirement analysis of system. Have transplanted embedded Web server and database, then carried on the development of the application program on the basis of here. Did the beneficial discussion and practice realize to communication protocol . Isolate communication protocol relevant part from other module , is it leave bigger upgrading...
