Hi,

 

I've designed new board using i.MX6 Q CPU and reference has been taken from Sabrelite board.

There is only differences in DDR3 interface like Data Bus mapping.  I've used straight D0-D64 between i.MX6Q and DDR3 (Micron) Chip  MT41J128M16HA-15E.

 

I am using OCDemaon USB Wiggler hardware and OCD Commander (Software) for JTAG programming in Windows 7.   

 

I am getting error below:

 

"Memory Write Error : 0x27800000 - 27801000

HALT"

 

I've tried DDR3 stress test at 400MHz and it was going till loop 9.  Then i just stopped it.

 

I am not sure where the exact problem is. 

It seems DDR3 is working but not sure.

Am i missing some hardware setting which should be done for fresh board?

 

Please let me know your views.
