Getting random exception ,when runs from DDRAm 0x20000000

Hi
I have developed a bootlader and the application for SAMA5D22 .The boot loader copy the application from flash to @0x20000000 of ddram2 and jump to this location.While code execution code resets , too many exceptions occurs-- exception 1, exception 2, exception 3 and exception 4.Now if I change the linker file DDRAM address to 0x26f00000 of application code download this newly build application in flash and when boot loader copy this application at 0x26f00000 and jump at 0x26f00000 location ,code executes pretty well. no exceptions at all. I am not getting what is special about 0x26f00000 address.Can any one help me to understand it.

Regards,
Smita

It's in the code that you "developed"!
