基于闪存的DSP在线编程及并行引导方法研究

Research on DSP online programming and parallel bootloader based on FLASH

分析了TMS320VC5402引导装载过程,给出了2种基于FLASH的TMS320VC5402引导表建立方法.针对后一种方法,以SST39VF800A为例介绍闪存的主要特点和烧写方法,讨论了用TMS320VC5402对FLASH进行在线编程实现16位并行引导.实践证明,该方法具有很大的灵活性和实用性.

By analyzing the bootload process of TMS320VC5402, two methods of creating boot table of TMS320VC5402 are presented based on FLASH. For the later method, here taking SST39VF800A as an example, the main characteristics and word program method of SST39VF800A are introduced,FLASH online programming with TMS320VC5402 is presented to realize 16_bit parallel boot.This method is very flexible and practical.
