Khadas VIM3L 안드로이드 12 빌드하기

소스 싱크

$ repo init -u https://android.googlesource.com/platform/manifest -b android-12.1.0_r27 $ repo sync

 

빌드 수행

$ source build/envsetup.sh $ lunch yukawa-userdebug $ make TARGET_VIM3L=true TARGET_KERNEL_USE=4.19 -j12

 

다운로드 방법의 경우 아래 안드로이드 11 글을 참고하면 됨

안드로이드 12부터는 따로 소스트리를 약간 변경하거나 하는 작업이 필요하지 않음

VIM3 / VIM3L 시리즈는 안드로이드 버전에 별 관련이 없다면 안드로이드 12 부터 작업해보는게 편할것 같음
