안녕하세요?

이번에 S3C6410 프로세서용 Android Kernel 2.6.29 이식 강좌를 올리니, 많은 도움 되시길 바랍니다.

여기에 기술된 절차는 실제로 aESOP S3C6410 2.6.29 커널을 제작할 때 사용한 방법 입니다.

1. Android Kernel 2.6.29 개요

1) 현재 발표된 최신의 안정화된 Kernel Version
2) 향후 Linux 공식 Kernel Version에서 Android Kernel과 통합
3) Cupcake 1.5를 완전하게 지원
4) 이 커널을 기점으로 Processor Kernel 을 Android 이식 방법에서,

     Android Kernel을 Processor에 맞는 Kernel 을 이식하는 방법으로 Android 이식 절차가 변경 됨
5) 강의에서 사용될 커널은 삼성에서 릴리즈한 SMDK6410용 2.6.28 Kernel을 기준으로 설명

2. 커널 소스 다운로드 방법

1) SMDK6410용 2.6.28.6 소스 :
http://git.kernel.org/?p=linux/kernel/git/kki_ap/samsung-ap-2.6.git;a=summary 의 Snapshot을 사용

(4월 30일 버전 - 현재 이솝 포럼의 S3C6410 자료실에 있습니다.)

2) Android Kernel 2.6.29 소스 :
http://android.git.kernel.org/?p=kernel/common.git;a=tree;h=refs/heads/android-2.6.29;hb=android-2.6.29 의 Snapshot을 사용

3) 해당 소스를 다운로드 후, ~/Android-2.9-AESOP 디렉터리를 생성한 후 압축을 해제
4) 크로스 컴파일러는 이솝 포럼 자료실의 arm-s3c6410-linux-gnueabi-gcc 4.2.4 컴파일러를 사용

3. Kernel에 포팅할 드라이버 목록

SMDK6410 2.6.28 커널에서 Android Kernel 2.6.29로 이식할 드라이버 목록
