Android Things란 무엇입니까?

구글의 IoT 플랫폼에서 나온 거예요.
발표할 때
Intel Edison
NXP Pico
Raspberry Pi 3
3개의 하드웨어 설치 가능한 OS 이미지는 Google에서 제공합니다.

Fastboot 설치

Android SDK를 설치하십시오.
특별한 설정 변경 등이 없으면 Mac는 아래에 있습니다.
~/Library/Android/sdk/platform-tools/fastboot


Intel® Plaatform Flash Tool Lite 설치

https://01.org/android-ia/downloads/intel-platform-flash-tool-lite
를 참고하십시오.
Mac의 경우 Plaatform FlashTool Lite5.5.2.0_mac64.pkg을 실행한 후 설치를 시작합니다.

감상

안드로이드 스마트폰과 태블릿PC로 ROM을 다시 태우는 순서는 랩베리 피3보다 Intel Edison에 안드로이드 씽스를 설치하는 것이 안드로이드 같다.USB로 직접 연결할 수 있으므로 이더넷 환경이 필요 없고 어플리케이션 개발 시 Wifi로 adb 연결 필요 없음
