안녕하세요. 6410에서 실습하고 있는 임베디드 입문자입니다.

지금 파일시스템을 생성해서 포팅하는데 문제가 있네요..

원래 nfs로 부팅하여 yaffs2이미지를 압축을 푸는 형태로 동작이 되었었는데. nfs부팅을 하지 않으려고

바로 u-boot에서 nand write 한 후에 부팅하려하는데 계속 막히네요.

커널은 2.6.21.5 버전이구요. 다음은 busybox를 활용한 파일 시스템 만드는 과정입니다.

busybox 버전은 1.19.3입니다.

1. make menuconfig & install을 거친 후 _install 디렉토리에는 bin, sbin, usr 디렉토리와 linuxrc가 생성되었습니다.

2. 여기에 커널부분쪽 init과정을 보니까 bin이나 sbin에서 init파일을 실행하기에 sysvinit 프로그램을 이용하여 sbin/init파일을 생성했습니다. sysvinit은 2.86입니다. 2.86.ds1-61.diff 패치까지 완료한 상태구요.

3. dev와 etc도 없었기에 디렉토리를 만들어서 dev 밑에 tty나 console등을 생성하고.. etc밑에 inittab파일을 다른 파일시스템의 것을 복사하였습니다.

4. 다음 mk2yaffs2image를 사용하여 yaffs2이미지를 만들었습니다.

5. uboot에서 tftp로 생성한 파일시스템을 nand write.yaffs 명령을 사용하여  파일시스템을 write했습니다.

6. 그리고 마지막 boot 로그입니다.

계속 이 커널 패닉이 일어나네요. init 파일 실행에 실패했다고... 사전 지식이 부족하여 어디부터 손을 봐야할지 모르겠습니다....
