Abstract


With the development of the Internet and the post-PC era, embedded systems become the focus of one of the IT industry, and presents a huge market demand. But at the same time a large number of embedded applications, the performance and functionality of the embedded devices put forward higher requirements. Now embedded devices generally require network support and multi-tasking ability, how reasonable choice of hardware platform, a good design of embedded multi-application integrated platform is the important subject of this thesis and resolve. ARM (Advanced RISC Machines) 32-bit RISC processor, with its high-speed, bottom-power, low-cost, functionality, and unique 16/32 bit dual instruction set and many other excellent properties, has become the mobile communications, handheld computing preferred processor, multimedia digital consumer and embedded solutions. The ARM company ARM7TDMI particularly suitable for low-power, require network support for the industrial equipment. But ARM7TDMI MMU module in the corresponding software implementations that require special handling, as the core of the kernel the S3C44B0X is a cost-effective Ethernet-based applications 16/32 bit microcontrollers ideal for embedded products. Embedded uClinux code openness and a powerful network function in the low-end embedded network devices widely used, has more advantages compared to other embedded operating systems, therefore this paper as a hardware platform operating system, and in this system to achieve the basic operation of the uClinux thesis describes the hardware and software platform can provide a starting point for good development for practical applications. Linux with its advantages have gradually become more and more widely, a good operating system uClinux as its derived many embedded systems. ARM as a high-performance, low-cost embedded RISC processors, has become the most widely used embedded processors. This article describes the ARM7TDMI kernel S3C44BOX processor and uClinux embedded operating system platform for the establishment, including the hardware structure, development environment, and development tools, special emphasis on the establishment of a cross-compiler environment and uClinux transplant. This work mainly as follows: ● analysis and transplantation famous bootloader program blob. ● solve difficult transplant uClinux operating system platform successfully ported uClinux. ● debug and improve the entire development system, to solve the problem of network instability, summarized summary of the development of embedded systems hardware platform design methodology and experience. Design results of this paper, can be used as a laboratory embedded applications secondary experimental platform for product development and teaching work.
