Hello Chetan.

Please make sure you are following (http://www.altera.com/support/kdb/solutions/rd07292010_420.html) correctly.

Is your DDR2 s1 address range 0x10000000 to 0x1fffffff and all the other components in between 0-0x0fffffff?

Also did you change /linux2.6/arch/nios2/include/asm/nios.h? (DDR2_TOP_BASE to 0x10000000, and DDR2_TOP_SPAN to 268435456 (256Mb))

Give them a try...

All the best,

Turhan
