[U-Boot] DDR3 initialization fails after cold boot

[prakash bedge]

Hi,



I am trying to initialize the DDR3 present on my board, using the u-boot
with DMA engine on my board.

My board is mounted on linux machine.



DDR3 initialization completes successfully after warm boot (given init 6
command on linux).



But the same u-boot code fails after cold boot (given init 0 command on
linux and then power on).



Also I am seeing that in u-boot timing might be not correct.

udelay(14000000)  function should generate 14 sec delay but it generates
delay of only 5 seconds.



I doubt that timing might be issue but I believe that in u-boot udelay
function is correct.



What should be cause behind this cold boot issue for DDr3 initialization?

Need some inputs. Please respond.





Thanks & Regards,

Prakash
