iMX6L lack of DDR clock

Hello,

 

We observed the lack of DDR base clock.

The clock periodically stops( 0V ).

 

It seems the cycle is in synchronization with LCD display's VSYNC and HSYNC.

We attached the waveform.

 

Could you let us know the reason about this issue?

Is this normal behavior?

 

Thank you.
