摘　　要：针对TMS320F2812平台产品后期软件维护升级过程中需要使用仿真器并拆机的繁琐操作问题,给出了一种通过串口烧写程序的方案。方案设计了一种加载程序,能够将应用程序从串口接收并烧写进相应的FLASH区域,使软件固化升级操作脱离了仿真器和开发环境。方案所设计的加载程序精巧,升级时只需要通过上位机传输并在RAM空间运行,不需提前烧录进产品FLASH中,从而降低了产品的升级维护难度。方案应用方便,适用场合广泛,具有较高的实用价值。In view of the tedious operation when upgrading software using the emulator or dismantling the equipment in the later software maintenance on TMS320F2812 platform products,this paper presents a scheme design of flashing program through serial port.In this design,the loading program is used to receive the application program from the serial port,and burn it into the corresponding FLASH area.With this method,the software upgrade operation gets rid of the simulator and development environment.The loading program designed in the scheme is exquisite.When upgrading,it only needs to be transmitted through the upper computer and run in RAM space,and there is no need to burn it into FLASH in advance,thus reducing the difficulty of product upgrade and maintenance.The scheme given in this paper is easy to use,widely used and has a higher practical value.
