라즈베리 파이 2 커널모듈 빌드


디렉토리 구조

linux 와 target_fs(rootfs) 그리고 tools는 git로 받고

modules는 linux 커널 모듈을 내려받기 위해서 빈 디렉토리로 생성한다.


~/rasp$ tree -L 2

일단.. modules 디렉토리 없이 그냥 하니 /lib 로 타겟이 아닌 호스트에 바로 복사하려는 만행을 벌이는데!!

$ make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- modules_install

scripts/kconfig/conf --silentoldconfig Kconfig

mkdir: `/lib/modules/3.18.10-v7+' 디렉토리를 만들 수 없습니다: 허가 거부

make: *** [_modinst_] 오류 1

라즈베리 파이 2 커널 바꿔치기.. 실패 ㅠㅠ

snappy SD 카드에

kernel.img를 바꾸니 무한 재부팅 -_ㅠ


config.txt에

kernel=kernel.img

이런식으로 넣으니 그냥 깜깜 무소식 -_-

음... make modules_install을 안해주고 해서 그런가?

ARCH=arm CROSS_COMPILE=${CCPREFIX} INSTALL_MOD_PATH=../modules make modules_install

2015.04.16 추가

시리얼 연결해서 머가 문제인지 확인

일단.. snappy의 경우 kernel.img는 바꾸어도 차이가 없고

kernel7.img를 바꾸어야 변화가 생긴다. 아마도 kernel7.img가 ARMv7용인듯 하다.

비글본 vs 라즈베리 파이 2

문서를 찾다보니 라즈베리 2랑 비글본 성능을 비교한게 있는데

비글본의 경우 싱글코어 1기가 / 2000MIPS 인데

Cortex-A8과 Cortex-A7의 차이인지 라즈베리를 오버클럭해서 1기가로 올리면 성능 차이는 거의 없다고 할 정도이다.

된다는거야 안된다는거야 -_-

일단은 cmdline 상에는 rootfstype 옵션이 ext4가 기본이라고 한다.

jffs2 rootfs

크게 어려운 건 없고..(?)

kernel 에서 jffs2를 지원하고

(cat /proc/filesystem 으로 확인)


mkfs.jffs2를 통해 생성

단, 몇가지 옵션을 주지 않으면 생성이 되지 않는 것으로 보인다.



+ flash 메모리에서나 쓸수 있지 sd는 못쓰는 듯?

에러를 다시보니 로그인 시간이 1970년! epoch로 되어있고

아마도.. openelec 처럼 기본적으로 타임서버를 통해 받아오지 않아 시간이 제대로 설정되지 않았던 것으로 보인다.

라즈베리 파이는 RTC가 없어서 매번 네트워크나 수동으로 잡아줘야 하는데..

snappy 버전에서는 일부러 빼놓은건가?


date 명령을 통해서 시간을 업데이트 하고

$ sudo date 0407225715

Tue Apr  7 22:57:00 UTC 2015

[링크 : https://www.linux.co.kr/home/lecture/index.php?cateNo=&secNo=&theNo=&leccode=244]


업데이트 하니 오홍!! 된다!

$ sudo snappy update

ubuntu-core    124 MB     [==========================================]    OK 

Applying [|]


헐.. 리부팅을 시키네 ㅋㅋ

Applying: Done

Reboot to use the new ubuntu-core.

라즈베리 pi + xbmc 리모컨 조사

어떤 수광부를 사야할지 몰라서

IrDA USB 동글부터 해서 이것저것 검색중..

NOTE: Qt is using double for qreal on this system. This is binary incompatible against Qt 5.1.

Configure with '-qreal float' to create a build that is binary compatible with 5.1.

Info: creating super cache file /home/minimonk/src/qt-everywhere-opensource-src-5.3.2/.qmake.super


Qt is now configured for building. Just run 'make'.

Once everything is built, you must run 'make install'.

Qt will be installed into /usr/local/Qt-5.3.2


Prior to reconfiguration, make sure you remove any leftovers from

the previous build. 



또 얼마나 걸리려나 ㅋㅋ

오전 10:17 2015-03-25


make clean 하고 컴파일 해서 그런가

14:03:18

4시간 걸림 ㅋ

일단은.. Qt 5.3 에서 기본적으로 설정되어있는 내용으로

Raspberry pi는 1, ARM11 용으로 설정되어 있다.

커널이 i7에서 3분 걸리던게.. 1시간 20분 걸렸으니

i7에서 30분 넘게 걸리던 qt 컴파일은... 10시간 이려나?! -_-a


+

그냥 걸어놓고 내려놨는데

다시 확인하니 20:54:36 컴파일 완료

거의 3시간 반 정도 걸린듯?
