ALTERA에서 Nios II 용 바이너리를 변환하는 녀석으로

확장자가 flash가 튀어 나오는데, 내부 포맷은 SREC 라고 한다.

Motorola에서 개발했으니.. 원래는 PowerPC 계열에서 쓰던 걸려나?

아무튼 기본 포맷 유형은 intel HEX와 유사하다.

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 compila‐

tion 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.
