축하 합니다.
지금 6410보드로 android를 포팅중입니다
android rfs를 nfs를 통해서는 잘 동작해서 메뉴창까지 뜨는데 문제는 onenand에 android rfs를 넣고 부팅하면은
kernel panic이 납니다.
udev와 관련 잇는것 같은데. 대체 왜 죽는지.
같은 커널이고 nfs와 onenand부팅 차이인데.. sysfs쪽에 write하는 부분이 문제 인것 같아 init.rc에서 sys에 write하는 부분을 전부
주석처리 해도 죽어버립니다
aesop에서는 저런 문제가 없었는지 nand쪽에 다른 처리를 해줬는지 궁금합니다
/dev/mtd0~6, /dev/mtdblock0~6 까지 노드를 직접 만들어 줬습니다.,

Kernel panic - not syncing: Attempted to kill init!
sys 관련 주석처리하면 더 에러날 가능성이 높을 듯 하고요....
onenand로 해보지 마시고, 일단은 sd로 함 해보시기 바랍니다. 그럼 답이 나올 듯 합니다.
onenand쪽 접근에 문제가 생긴것인지 아닌지....
