펌웨어가 나가면 Bootloader새로 구워야하는데, Arduino IDE에서 안되면, 아래처럼 Arduino avrdude로 커맨드로 하면 억지로 되긴한다.

초기 설정은 아두이노 홈피에서 Arduino as ISP 로 설정하는 법과 SPI로 연결한뒤에 하는 것.

인터넷에 있는 2단계 가이드대로 따라했던것이고 결과 로그까지 첨부한 것임.

국내에 보급되고 있는 아두이노중에, 아두이오 Uno베이스로 328P 를 쓴 것들에서, USB가 FTDI나 CH340쓴것으로 약간 사용성이나 문제가 갈리는 것 같고, 보드에 OSC의 클럭에 따라서 PC호환성이나 동작안정성, 고장률이 다른것으로 보임. 뭐 일차적으로는 핀에다 마구 꼽는것에 따라서 쇼트발생이 잦아서 보드가 나가는 경우도 많아 보이고, 전원 부족으로 잠시 안되는 경우도 있어보임.... 결론은 뽑기운이 많이 따라줘야함. 윈10에서 USB 드라이버 호환성문제도 있어보임.... 쩝.
