Description: MCU为LPC2220,FLASH为39FV1601（地址0x80000000）,外部一个SRAM（地址0x81000000），程序用ADS编译，
用分散加载，程序0x80000000开始引导，FLASH操作在LPC2220内部RAM运行。
实现的作用为开机等待2秒左右若PC发来连接指令将进入BOOT部分，若超时则COPY应用程序到外部RAM开始运行。
抛砖引玉，可以认识到分散加载，BOOT的基本原理及方法，该程序已可完成所有功能，但可能仍然需要补足一些
如FLASH坏区检查等，不足之处，敬请自己修改过来拉。
用于串口方式下载，波特率38400。-MCU for the LPC2220, FLASH for 39FV1601 (address 0x80000000), an external SRAM (address 0x81000000), program compiled using ADS, with scattered load, procedures 0x80000000 started guide, FLASH operating in the LPC2220 internal RAM to run. The realization of the role of waiting for the boot for about two seconds to connect if the PC-fat BOOT command will enter a part, if the overtime is COPY application to the external RAM is running. Initiate realize decentralized load, BOOT basic principles and methods, the program has to be completed by all the features, but it may still need to make up for some areas such as FLASH bad checks, the inadequacy of your own modifications pull over. For serial download, 38400 baud rate.
