Running NIOS program from external SDRAM

Thanks for the reply Slacker.

My next question is how would I implement this?

I am using a DE0-nano board which has EEPROM and an EPCS64 serial configuration device which I could use to store the code at first . I can load the NIOS II program there but how do I then point the reset address to it?

How would I create this boot copier/loader and get it to start copying the code to the SDRAM when the NIOS starts? . Would I need to write start up code?

I have wrote code for physical MCUs before and I know that a linker script is required to memory map the sections for the MCU and then some start-up assembler code which runs from the reset address which then jumps to main(). Are these created automatically by the Nios IDE or how does it work?

Thanks,

Paul
