Description: 设计与实现了一个基于 PXA255 的 bootloader。PXA255 是 Intel Xscale 系列处理
器之一,Xscale 核心是与 ARM V5TE 构架兼容的,是一个典型的 ARM 系统。软件采用 Linux
为操作系统。课题除了实现 bootloader 的基本功能(加载内核镜像)外,还将它实现成一个
更加复杂的系统,包括 bootloader 的两种模式的支持和切换,以及增加对一些硬件模块的
支持,这些模块包括:串口、USB、NOR FLASH 的擦写等等,以方便开发人员进行调试以及
开发,例如:通过串口以及 USB 接口传输数据以更新内核镜像;擦写 FLASH 以更新 FLASH
内容。-Design and Implementation of a PXA255 based on the bootloader. Intel Xscale PXA255 series processors is one, Xscale core is compatible with the ARM V5TE framework, is a typical ARM systems. Using Linux as the operating system software. Bootloader issues in addition to achieving the basic function (loading the kernel image), the will to achieve it into a more complex system, including the bootloader of the two modes of support and switching, and increased support for some hardware modules, these modules include: serial, USB, NOR FLASH the erase, etc., to facilitate the developer for debugging and development, for example: serial and USB interface to transfer data to update the kernel image erase FLASH FLASH to update the content.

Description: arm通用启动程序,本课题硬件上采用了Intel Xscale系列的PXA255作为处理器,Xscale核心是与ARM V5TE构架兼容的,因此具有一定的代表性,并以此来搭建课题的硬件实践平台,软件上以Linux作为操作系统。而在具体的实现上目标是除了实现bootloader的基本功能外,还将它实现成一个更加复杂的系统,即增加对硬件电路板的支持,以方便开发人员进行调试以及开发。因此,本文重点阐述了实践上具体的设计,具体的实现以及简单评估了它的作用。最后,对实现的bootloader进行了扩展:即在阐明ARM嵌入式系统中bootloader的一些共同点之后,介绍了如何对其他ARM系统进行移植,以做到通用性。-arm universe bootloade very detail document:
