摘　　要：介绍了TI公司数字信号处理器TMS320F2812的引导方式、Flash编程方法、Flash启动流程。在此基础上提出了一种基于429总线的TMS320F2812程序的远程加载方案,并详细阐述了软硬件的实现过程。该方案摆脱了Flash编程时对JTAG接口、RS232接口的依赖,非常适用于军用领域,具有较大的实用价值。Boot mode and flash programming method of digital signal processor TMS320F2812 which produced by TI were introduced in the paper, as well as start flow of flash. Based on this description, a method of long distance flash programming to TMS320F2812 based on 429 Interface was proposed, the execution process of hardware and software was also expounded. The new programming method through 429 communication interface instead of JTAG and RS232 that is very suitable for the army used area and has great value in practice.
