stareware 读取nand时间不一致问题



问题是:
同样的代码,在CCS调试仿真是显示是,

  • C674X_0: Output:         PLL0 init done for Core:456MHz, EMIFA:114MHz
  • C674X_0: Output:         DDR initialization is in progress....
  • C674X_0: Output:         PLL1 init done for DDR:156MHz
  • C674X_0: Output:         Using DDR2 settings



读取nand一页的时间,假设为10ms;


利用软件AISgen_d800k008,将.out ---> .ais,烧写到nand中,使用nand启动方式 boot  [5] =1,[6] =0 ,启动后,同样读取nand一页的时间,假设为40ms;
