摘要:

为解决特殊场合嵌入式设备程序升级困难，提出了一种基于串口的TMS320F2812程序动态加载技术。该方法充分利用F2812丰富的片内存储器资源和支持在线编程特点，采用二级引导方式，通过调用API编程函数对片内FLASH擦除和烧写，实现设备程序的在线加载。实验证明，该方法具有烧写稳定、效率高、操作方便等优点，能够应用于嵌入式设备程序的远程升级中。

Abstract:

A new dynamic loading technology is proposed for TMS320F2812 programs based on serial communication, to resolve the difficulty of upgrading embedd ed equipment software in special occasions. This method takes full advantages of F2812′s features, such as rich onchip memory and supporting online programm ing, adopts secondary booting algorithm, and calls APIs to erase and program on chip FLASH to realize online loading of embedded devices. Experiment resu lts show that this method is featured by stable programming, high eff iciency and easy operation,and can be applied to remote upgrade of embedded equi pment software.

Key words: digital signal processing serial communication dynamic loading secondary boot
