vivi是MIZI公司开发的系统引导程序,原本只支持串口下载。本文以S3C2410处理器加CS8900网络芯片为例,介绍一种在vivi基础上增加网络支持的设计方法，使vivi能够通过TFTP下载文件，可以有效地缩短系统的开发周期，方便用户使用。
关键词 vivi Bootloader TFTP协议 网络功能扩展
随着嵌入式的发展，基于ARM的系统越来越流行。在开发ARM系统时，第一步就是要选择一种合适的Bootloader。目前网络上可得到的Bootloader很多，一般几十KB，所以除非要求把Bootloader限制在几KB以内，否则没有必要自己去写一个Bootloader。Bootloader一般存放在Flash中。当前主流的Flash分为NOR Flash和NAND Flash。前者价格比后者高出很多，而性能相差无几。如果系统采用的是NAND Flash，那么vivi可能会是一个好的选择。
