摘要
嵌入式系统产品开发的整个过程按照先后顺序包括:在给定的硬件模块上移植bootloader(引导程序)、移植嵌入式操作系统内核、移植根文件系统、编写特定外围设备的驱动程序和编写应用程序。移植bootloader是所有软件层面工作的第一步,需要考虑微处理器和外围存储器件的具体特征,有一定的难度,该文基于ARM Cortex A8内核的S5PV210微处理器,详细分析其上电后从启动介质中启动软件系统的过程。
The whole process of embedded system product developmentin accordance with the order including: bootloader transplantation(bootstrap) in givenhardware module, transplantation of embedded operating system kernel, transplantation of root file system,programming for driver and application for particular peripheral device. Bootloader transplantation is the first step of all software work, need to consider the specific characteristics of microprocessor and the external storage device, has a certain degree of difficulty, this paper has detailed analysis startup ofsoftware system from start medium using S5PV210 microprocessor based on ARM Cortex A8 kernel.
