According to my experience, BSP linker tends to assign .text to the largest memory in your system, ie DDR3 memory. If you want to still run from onchip-memory, you will need to modify the linker script via nios2-bsp-editor.

I am suspecting issue with the DDR3 path. Is both Nios and DDR3 running at the same clock frequency? Is there any timing failure reported in Quartus?
