Hi,
I got the root cause. It was the DDR related issue while reading the DMC
registers.
Now the problem is solved. I am not not getting exception error after
enabling MSR_EE.
I am moving to use the latest u-boot code (2010.03) believing that there
might be fixup for timing issue I am facing when

Hi Stefan,
But, my DDR3 initialization seems to be completed and I am not getting any

Another issue I am facing that if I add 2 pritinf functions before or after
DDR initialization the DDR3 initialization code hangs in between
and if I remove the printf functions, ev

Hi Stefan,
Thanks.
Shall I need to add sleep() command in the interrupt_init or before it?
I am using Samsung M391B2873EH1-CH9 series 1 GB DDR3 and Denali controller
is being used for driving DDR3.

Hi All,
I am facing an error while porting u-boot for my platform because if
exception error.
After running the u-boot to detect the DDR and flash u-boot hangs after
showing the serial console output. In debugger I am seeing PC at 0x0400
address which the exception handler vector address.
