| 摘 要： | 以TMS320F2812为基础，详细分析了该芯片上电后系统的引导过程，针对此类以MCU／DSP为核心的嵌入式产品升级、维护时FLASH编程不便的问题，依据其内部固化的BootROM以及FLASHAPI的原理，介绍了一种基于RS-232的FLASH编程方法。这种方法较传统FLASH编程，具有编程方便、快捷、成本低等优点，并在实验中验证了结果，此方法可行。

| Abstract: | To solving the problem while updating the program on the embedded products, this paper, based on TMS320F2812, discussed the methods and problems of programming FLASH on MCU/DSP. By studying the theories of the boot rom and the FLASH API, the way programmed FLASH through RS- 232 is introduced, which is available for convenience, fast and low cost, and the feasibility has been proved by the experiment. |
