1. Yocto의 Licence 정보 와 Build 구조
Yocto 자체 Poky License (GPL/MIT)
Yocto의 내부의 Poky의 License
Yocto Recipe 작성방법 (반드시 확인 및 이해)
1.1 Yocto Source의 License 설정
Yocto의 기본인 poky에서 모든 LICENSE를 설정하는 곳이 별도로 존재하며,
이 기반으로 Recipe에서 선언을 하면 쉽게 License 관리가 된다.
- Yocto의 licenses.conf 설정확인

2.1 Build Space에서 License 정보확인
- 사용된 Package들의 License 조사
아래와 같이 찾아보면, tmp/deploy/licenses 에 기본적으로 Yocto에서 사용되어지는 Package들 License를 쉽게 찾을 수 있다.
그 아래를 보면 GCC License가 두 종료로 분리되어 나오
$ find . -name licenses
./tmp/deploy/licenses
./tmp/work/imx6sxsabresd-poky-linux-gnueabi/base-files/3.0.14-r89/licenses
./tmp/work/cortexa9hf-neon-poky-linux-gnueabi/util-linux/2.32.1-r0/util-linux-2.32.1/Documentation/licenses
./tmp/work/cortexa9hf-neon-poky-linux-gnueabi/gnutls/3.6.7-r0/gnutls-3.6.7/lib/extras/licenses
./tmp/work/x86_64-linux/util-linux-native/2.32.1-r0/util-linux-2.32.1/Documentation/license
- 사용되어지는 Package들의 License 정보확인
Build Space에서 실제 빌드된 Package 정보들이 확인 가능하며, deploy에 배포된 licenses 정보들이 별도로 관리가 되어진다.
이곳에서 관련 licenses 정보들을 확인

- Image에서 사용되어진 License 확인
사용되어진 Image의 Package들의 License 정보를 알파벳순서로 확인가능하지만,
주의해야할 것은 모두 나오지는 않으며, 안나오는 것은 상위 Package에서 직접보자.
안나오는 경우는 LICENSE를 CLOSE해버리면 당연히 나오지 않게된다.
나의 경우 간단히 Uboot와 Yocto에서 사용되어지는 Python의 License들은 나오지 않았다.
