几种Bootloader简介(二)

  l         ViVi

        vivi是什么？

        vivi是由mizi公司设计为ARM处理器系列设计的一个bootloader，因为vivi目前只支持使用串口和主机通信，所以您必须使用一条串口电缆来连接目标板和主机。

       它有如下作用：

       1）、 把内核(kernel)从flash复制到RAM，然后启动它

       2）、 初始化硬件

       3）、 下载程序并写入flash(一般通过串口或者网口先把内核下载到RAM中，然后写入到flash)

       4）、 检测目标板(bootloader会有一些简单的代码用以测试目标板硬件的好坏)

       vivi的使用方法

       摘录自vivi的guide.txt，稍作修改。

1. Introduction

This document explains to you:

 

1) compiling the vivi

 

2) interface an user and the vivi

 

3) avaliable user commands

1.1. Definitions

vivi

 

The vivi is one of arm boot loaders.

 

Autoboot mode

 

The vivi has two modes. one of these is autoboot mode. This is a default mode. In this mode, The vivi automatically boot-up the linux kernel when a delay time is expired.

 

Prompt mode

 

One of vivi's modes is prompt mode. In this mode, An user is able to command to the vivi doing something.

 

Host platform

 

Generally, an engineer develop the software on the powerful destktop computer (not on the embedded machines). This descktop called host platform.

 

Target platform

 

Target platform means developemnt boards or embedded machines.

1.2. vivi的目录结构及文件
