커널에서 어떻게 설정하고 어떻게 해야 하나...

디렉토리 구조
linux 와 target_fs(rootfs) 그리고 tools는 git로 받고
modules는 linux 커널 모듈을 내려받기 위해서 빈 디렉토리로 생성한다.
~/rasp$ tree -L 2 . ├── linux ├── modules ├── target_fs └── tools ├── arm-bcm2708 ├── configs ├── mkimage ├── pkg ├── sysidk ├── test_code └── usbboot |
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

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.
Uncompressing Linux... done, booting the kernel.

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.

일단은 cmdline 상에는 rootfstype 옵션이 ext4가 기본이라고 한다.

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?
