摘　　要：仿真器连接DSP进行程序升级给软件维护带来巨大麻烦。利用TMS320F2812芯片的内部丰富资源和支持在线编程的特点,介绍一种应用软件远程更新方法。包括一个通用的BOOT程序和两种生成可烧写文件的方法,满足了TMS320F2812产品的应用开发以及更新维护等需求。方法已应用于多个产品研制中,实验结果表明方法操作方便、加载结果稳定可靠。Emulator connected to the DSP program upgrade to the software maintenance is a huge trouble. Using the rich resources of the TMS320F2812 chip and supporting the characteristics of online programming,a remote updating method for application software is introduced in this paper. Including a generic BOOT program and two methods of generating a writing file, its meets the application and development of the product and updating maintenance requirements. The method has been applied to the development of a number of products, the experimental results show that the method is convenient to operate and the load- ing result is stable and reliable.
