LS1043A, DDR4 controller is not up and DDR clock is not coming.

Question asked by Logesh S on Aug 3, 2017

We are using LS1043A processor in our module.

 

While board bring up, we are booting through SD card.

RCW has been loaded from SD card.

Processor has been released HRESET to the peripherals.

(PBI SRC is selected as SD Card)

But DDR4 controller is not up and DDR clock is not coming and SD Clock is coming.

 

I believe in LS1043A after loading the RCW data, it struck at PBI.

 

Please let me know the possible reason, why DDR clock is not coming.

 

Thanks

Logesh
