Research of fast self-start up based on TMS320C6416

摘要

The quality of boot-loader is related to the reliability and the operating speed of the system during the development process of DSP. Based on the development experience, on-line fast programming for flash memory is proposed to complete the external configuration for DSP via JTAG port and fast-automatic booting for DSP is achieved. Taking AMD'S flash memory (AM29LV400) as an example, the article analyses the principle of writing Boot-Loader and introduces the process of building linker command file detailedly. In addition, it also gives the steps of on-line programming for flash memory. The technology and methods adopted in the design are flexible, stable and reliable which would be practical for the DSP developers.
