Hi,

 

I want to make sure one of initial calibration value of DDR stress tester tool.

I think following value set instead of reset value: 0x40404040 for the iMX6Q-SabreSD calibration.

 

     MPRDDLCTL PHY0(0x021b0848)⇒0x4B434748

     MPRDDLCTL PHY1(0x021b4848)⇒0x4445404C

 

Why such value set? Is it mandatory?

 

Actually we expected less than 0x40404040 for read DQS delay line calibration.

 

In such case can we set less initial value for it?

 

Thanks.
