Hi Julien_92,

I have already make it follow what Cris72 had said, I copy the steps below, besides, you can may some useful info at alterawiki & search EPCS bootloaders.

- unzip the files in a new directory

- open Nios II command shell and go there

- change EPCS_SRC_ADDR in boot_loader.h with desired boot address for Nios application

- build the custom bootloader, which generates a epcs_controller_boot_rom_A.hex file (simply type 'make')

- replace the existing epcs_controller_boot_rom.hex file in your Quartus project with the newly generated one (thus removing _A)

- select Quartus Processing menu, then Update Memory Initialization file

- select Quartus Processing menu, then Start -> Start Assembler

- the generated sof file will boot from the specified epcs address
