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Boot ROM以及FLASH API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。
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.
