그간 미뤄오던 USBASP의 펌웨어 업그레이드를 진행 했다.
달라진건... warning 이 안뜬다는거랑 프로그램 속도가 좀 더 빨라진것 같은 느낌...?
까먹기전에 역시 메모...
준비물 : USBASP 2개 (한쪽은 주는쪽 한쪽은 당하는(?)... 쪽)
(서로 번갈아 가며 2번 하면 둘다 펌업이가능 합니다만... 1개만 있으면 아쉽게도.. 불가.;;)
타겟에 JP2 를 쇼트 내도록 합니다.
(이거 몰라서 왜 안되징...?? 하며 1시간 헤메었네요 ㅜㅜ)
소스코드 다운로드

압축해제 후 bin 폴더안에 hex 파일을 찾는다.
그리고 아래 명령어로 플래싱을 한다.
(-p m8 옵션은 ATMega8A MCU 이다. 혹시 다른 MCU 라면 해당 모델로 바꾸도록 한다)

끝... (이래 간단한 것을...;;)
