摘　　要：文章介绍TMS320F2812的Boot Loader工作方式和十六进制文件数据转换。通过Bootloader中串口加载方式实现F2812片内FLASH在线编程,该方法不需要在FLASH中驻留编程软件,只需同过串口将编程软件加载到内部RAM中执行。该编程技术减少了应用程序的冗余代码,提高了应用程序的可靠性,满足F2812的工程应用中产品软件升级维护的需求,通过简单的硬件设置及软件设计,可靠的实现了F2812片内FLASH在线编程。The paper introduces the TMS320F2812 Boot Loader working mode and the sixteen hex file data conversion. The method of flash programming by Serial loading mode in Bootloader does not need reside programming software in FLASH,which just needs execute the programming software into the internal RAM. The technology has reduced the redundancy code of the application, improved the reliability of the application, and met the requirement of the product software upgrade and maintenance in the engineering application of F2812. Through the simple hardware design and software design, the F2812 chip in FLASH was realized.
