며칠전에 OpenOCD 0.2.0이 나온것을 새로 확인하였습니다.

이제는 Coretex-A8까지 지원하려는것 같더군요.

AVR(ATmega128)도 지원합니다. ^^;

거의 9개월만에 보드를 꺼내서 JTAG을 붙여보았습니다.

빌드방법도 바뀌고 사용법도 조금 바뀌어서 소개하고자 합니다.

빌드방법

  인터넷검색을 하니 중국사람들이 이미 방법을 소개하고 있었습니다.

    (How to build OpenOCD for windows - jordon的?? - CSDN博客)

  설명대로 빌드(Windows XP용, FT2232)하니 쉽게 빌드되었습니다.

사용예:

  첨부한 화일을 적절한 디렉토리에 풀어놓습니다.

  Target에 JTAG(FT2232)을 연결하고  부팅합니다.

  cmd창을 열어서 openocd.exe를 실행합니다.

  다른 cmd창을 열어서 telnet localhost 4444로 연결을 합니다.
