Cache和MMU的设置:指令 Cache可以打开也可以关闭:数据 Cache必须关闭;上海嵌入式家园一开牧椒商城嵌入式家园阙扯:ww.embedclub.com淘宝城网址http://embedclub,taobaocom/上海嵌入式家园-开发板商城贺工www.embedclub.com但是在刚上电启动的时候,一般连内存掉制器都没有初始化过,根本无法在主存中运行程序,更不可能处在内核启动环境中。为了初始化及其他外设,使得内核可以在系统主存中运行,并让系统符合内核启动的必备条件,必须要一个先于内核运行的程序,他就是所谓的引导加载程序(而并不是才需要,而是几乎所有运行操作系统的设备都需要。我们的的就是的一部分(只是前期引导,后面一般还有外中的各种),对于来说,的功能和选择综上:所述是在操作系统内核启动之前运行的一段小程序。通过这段程序我们可以初始化硬件设备,从而将系统的软硬件环境带到一个合适的状态,以便为最终调用操作系统内核准备好止确的环境,最后从别处(、以太网、)载入内核映像到主存并跳到入口地址。由于需要直接操作硬件,所以它严重依赖于硬件,而且依据所引导的操作系统的不同,也有不同的选择。对于嵌入式世界中更是如此。就而言,如果是引导般选用韩国的公司设计的或者软件工程中心的,如果是引导,就选用。如果是开发构架下的,就可选用由和发布的。如果是要引导系统,可以选用同是公司开发的所以在嵌入式世界中建立一个通用的几乎是不可能的,而可能的是让一个代码支持多种不同的构架和操作系统,并让她有很好的可移植性。就是攴持多平台多操作系统的一个杰出代表。这也是的优势所在,因为如果在开发时熟悉了,再转到别的平台的时候,就可以很快地完成这个平台下的移植。而且的代码结构越来越合理,对于新功能的添加也十分容易次推荐阅读:嵌入式系统技术内幕上海嵌入式宗回-歇板商城嵌入式家园阙扯:ww.embedclub.com淘宝城网址http://embedclub,taobaocom/上海嵌入式家园-开发板商城贺工www.embedclub.com第章简介U-boot的起源是的简称,其含义是,是遵循条款的开放源码项目。最早德国软件工程中心的基于和的源码创建了工程项目,此后不断添加处理器的支持。而后,移植到平台上,创建了工程项日。最终,以工程和工程为基础,创建了工程年月日第一个版木发布,同时和停止维护而今作为一个主流、通用的,成功地被移植到包括等主流休系结构上的百种开发板,成为功能最多、灵活性最强,并且开发最积极的廾涼日前仍然由维护U-boot的开发情况和资源最早的版本号是由来表示的,从直发展到。之后便开始使用年份加月份的表示方法,从到现在的平均每个多月出一个新版本。每次代码的结构和定义都会有一些修和改进,其代码越来越规整,功能越来越强,但是移植的难度反而越来越小,需要修改的地方越来越少不仅有主线版本,在的代码仓库中还有各个构架的分支版本些分支会在一定的时候将修改汇入主线。下面总结一下关丁源代码的网络资源官方链接德国软件工程屮心主页官方主页注意其中的邮件列表链接官方源码下载官方代码仓库针对的修改于机的源码上海嵌入式宗回-歇板商城嵌入式家园阙扯:ww.embedclub.com淘宝城网址http://embedclub,taobaocom/上海嵌入式家园-开发板商城贺工www.embedclub.com的源码(针对源码(针对上海嵌入式宗回-歇板商城嵌入式家园阙扯:ww.embedclub.com淘宝城网址http://embedclub,taobaocom/上海嵌入式家园-开发板商城贺工www.embedclub.com第章开发环境搭建交叉编译工具链的安装编译公A的时候,必须使用交叉编译工具链。你可以使用友善之臂提供的交叉编译工具(版本),也可以使用或自己编译一个。至于如何用工具自己编译交叉编译工具链,请看的博客的相关文章:用建立—交叉编译环境建立交叉编译环境(以()为例)在编译好交叉编译工具链后,要在环境变量的中添加编译工具的路径(也就是所在的路径),这样在编译时系统才找得到编译器的命令。在下的修改方法如下:在最后加上:交叉编译工具的路径网路服务的设置在使用的时候常常会用到宿主机的和这两种网络服务,所以最好在开发前设置好。下面以下使用安装为例,简单介绍一下安装配置过程:安装配置服务安装酣置服务的大致步骤如下:()安装和程序()修改配置文件()根据配置文件的跻径,建立日录,并修改日录权限;()重启服务()本地传输测试。以下是一个安装和配置主要步骤的脚本,大家参考:你想要的目录路径上海嵌入式宗回-歇板商城嵌入式家园阙扯:ww.embedclub.com淘宝城网址http://embedclub,taobaocom/上海嵌入式家园-开发板商城贺工www.embedclub.com你想要的日录路径建立目录,并修改目录权限:重启安装配置服务安装配置服务的大致步骤如下:()安装内核服务;()重新配置服务,修改和配置文件,重启服务()修改服务的配置文件添加服务∏录和配置,重新导入配置()重启服务,并检查可挂载的日录()在本地挂载测试以下是一个安装和配置主要步骤的脚本,大家参考:上海嵌入式宗回-歇板商城嵌入式家园阙扯:ww.embedclub.com淘宝城网址http://embedclub,taobaocom/上海嵌入式家园-开发板商城贺工www.embedclub.com对选特别要注意上面的的形式,以前是形如,现在是掩码为数的形式。用旧的格式可能会出问题具体的说明建议看册:串口终端程序的安装配置在使用的时候,必然会用到串口与开发板进行通信,所以串口终端程序必不可少。下面简单介绍下常用的牛凵终端:和的安装配置(以下使川安装为例)。的安装配置(推荐安装)在下是通过串口传输文件到开发板,就属比较好用上海嵌入式宗回-歇板商城嵌入式家园阙扯:ww.embedclub.com淘宝城网址http://embedclub,taobaocom/
