DE0-Nano NIOS II Question

I understand how to change an sof file to a jic, so that it can automatically run the code when the DE0-Nano gets turned on.

My question is how do i make my program run automatically when after i unplug and plug the board back in. Without having to Press run As NIOS II hardware?

    In DE2-115 there is a switch that allow you to choose running the FPGA from EPCS controller. I am not sure if DE0-nano has the same

    I have A de0 NANO TOO and i am able to download jic rigth but when i try to use de flash programer(sof+elf) it dont work ..

    The error in the flash programer is: can't find the epcs! and show me the adresses in wich are looking..And the adresses are good i comprae with tne qsys...

    This is wear becouse de jic works fine ......so the epcs have no problem...

    I have the epcs controller on my qsys i am using regular i/o in the toplevel entity..i put the reset vector to the epcs controller in the cpu..

    i dont`t know what to do ...

    Maybe this is relevant ...

    i find out that the epcs from my DEo nano is epcs64 not the epcs16 that appears in the usermanual...

    I connect the reset of the debug_module in the cpu to the reset of the epcs_controller in QSYS and it works...
