Figure 2: Memory Map of a System Using UFM with memcpy-based Boot Copier
e memcpy-based boot copier is automatically incorporated as part of the:
• HEX le during memory initialization le generation ("mem_init_generate" target) in the Quartus
Prime Programming Flow method
• SREC image (*.ash) le during elf2ash utility execution in the Nios II Flash Programming Flow

EPCS Controller-Based Boot Copier
EPCS controller-based boot copier supports EPCS memory only. Boot copier is stored in the ROM within
the EPCS ash controller. e boot copier is included during Qsys and Quartus Prime project compilation
time.
