Problem Description :
Use USB explorer to view usb packet. find that USB explorer display CSW packet before system send CSW command on BF606.

Increase DDR2 clock to solve the problem.
PLL clock is 400MHz, system clock is 400MHz, DDR2 clock original is 133MHz, Increase DDR2 clock to 200MHz, system as I expected execution.
Why DDR2 clock affect the program execution sequence ?
