GAPD-7000 Uart 접속 방법 및 결과

GAPD-7000의 UART에 접속하기 위해서는 일단 가공이 필요하다. UART 포트의 흔적이 기판에만 존재할 뿐 점퍼 케이블을 꼽을 수 있는 핀은 존재하지 않기 때문에, (J3라고 적힌) UART 포트 주변에 플럭스를 칠하고, 핀을 납땜 하자.

통신 속도는 115200이며, PuTTY 사용시 Parity와 Flow control 모두 None으로 잡도록 한다. 맨 좌측 부터 Vcc, Tx, Rx, GND 순이며, Vcc, Tx, Rx에 Vcc, Rx, Tx (시리얼 통신이다!) 순으로 연결만 해주면 공유기와 통신이 가능하다. 출력되는 로그를 보면 알 수 있는 것들이 많은데 이것에 대한 설명은 생략하도록 하겠다. Broadcom의 CFE를 개조하여 펌웨어를 만들었다는 것을 보고 알 수 있다.
