DENX ELDK version 4.2 build 2008-04-01
Linux 2.6.25.5 on a ppc
cpu87 login: root
루트로 로그인이 안됩니다..
root 로그인이 가능하게 하는 방법 좀 가르쳐 주시면 감사 드립니다.
bootargs 항목의 내용을 setenv bootargs 명령으로 똑같이 써준 다음 맨 끝에 single 이라는 단어를 추가하여 엔터를 칩니다.
setenv bootargs root=/dev/nfs .. (중간생략) .. single
boot 명령을 내려 부팅시켜 봅니다.
ELDK를 써본지 오래되서 제대로 single 옵션이 ELDK에서도 적용되는지는 지금 당장은
확인시켜드릴 방법이 없군요. 위에 적은 내용은 x86 시스템을 기준으로 적어본것입니다.
직접 해보시고 결과를 알려주시길 부탁드립니다.

답글 감사드립니다.
로그 화면 입니다. 문제점 지적 부탁드립니다.
리눅스 debian
보드 cpu87
리눅스나 유닉스에서 잘 되어야 할게 안되는 경우 대부분 퍼미션(실행권한)의 문제일 경우가 많습니다.
혹시나 ELDK를 설치한 다음에 아래의 두개의 작업을 빠뜨린게 아닌지 확인해 보시기 바랍니다.
잘 기억이 안난다면 그냥 한번 더 실행해주는 셈치고 따라 하면 됩니다.
