摘要
通过对OMAP启动方式的分析,针对OMAP需要从外部Flash启动、耗时大、风险高的缺点,提出了一种多级启动的Boot Loader设计方案。该方案通过两级启动,在RAM中运行Boot Loader,降低了代码运行的风险,减小了Boot过程的耗时。实验证明,使用该方法拷贝程序的耗时能够减少20%左右。
To overcome the shortcomings of OMAP＇s external Flash booting mode, which will lead to much time consumption and high risk, a multi-level Boot Loader for OMAP is developed based on analysis of OMAP＇s booting mode. The multi-level Boot Loader runs in RAM through two levels booting which will cause lower risk, and the time consumption is about 20% less than before according to the experimental results.
