1.4.2. EPCS Controller-Based Boot Copier

EPCS controller-based boot copier supports EPCS memory only. Boot copier is stored in the ROM within the EPCS flash controller. The boot copier is included during Qsys and Quartus Prime project compilation time.

The next stage boot image is located in the EPCS memory flash. The EPCS controller-based boot copier is automatically appended into the SREC image (*.flash) file during the elf2flash utility execution in the Nios II Flash Programming flow method.

Note: Quartus Prime and Nios II Flash programming flow is briefly described in the Nios II Booting General Flow diagram.
