INCLUDE SOFTWARE INTO EPCS (.jic)

OK.

Your processor has a reset vector which tells it the adress where it has to begin to load the code.

When you use eclipse to load the code, the reset vector set at Onchip_ram is good because eclipse writes directly the RAM by JTAG. But when you want to load the software from a flash memory, you have to tell the processor to take the code from this flash by his own. And that is what the "epcs_flash_controller" do.

This IP has a small ROM which contains some code. This code only read a flash memory and tells the processor to start from here.

So add this IP in your Qsys, set the reset_vetor in your processor IP and it should starts.
