CYCLONE 使用bootloader方法

Steps:

• open Nios II command shell and go to bootloader project directory
• 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 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 address
