Thanks for the answers, however there is still a missing element, provided that I add an external memory controller into the Qsys system and link the Nios II instruction master to it, the question still remains as to how will I instruct Eclipse IDE to put the code into that memory device?

You can also specify your external memory module in the settings of your NIOS processor in qsys ("reset vector memory" and "exception vector memory") ... see screenshot below.

Then, (as I suppose) the memory selected in these options, is "picked up" when BSP is generated.
