안녕하세요..

현재 yaffs2로 마운트하여 테스트 중입니다.

아래와 같이 wifi를 setting에서 wifi on을 하면 모듈이 정상적으로 로딩된후

E/WifiHW ( 825): Unable to open connection to supplicant on "/data/system/wpa_supplicant/eth0": No such file or directory

이런 메세지가 나옵니다.

현재 안드로이드 소스에서 wlan0로 되어 있던것을 모두 eth0로 변경한상태입니다.

도움 부탁드립니다.

감사합니다.

init.rc wifi관련 부분입니다.

==> 주로 오드로이드를 많이 참고했습니다. 차이점은 오드로이드의 경우 모듈이 빌트인되어 있는정도 입니다.

제가 지금까지 테스트 해본 결과로는 /data/system/wpa_supplicant/eth0 경로는 wpa_supplicant의 control path인데, 저게 조금 늦게 생성되는 경우가 있었습니다. 그래서 wifi.c에서 저 경로를 확인하는 부분에서 생생되어 있지 않으면 5초간 확인하는 방식으로 변경하였더니 더이상 문제가 발생하지 않았었습니다.

socket 관련 파일이네요.

늦게 생성되는 경우가 없어야 합니다만.........신현호님께서 그런 일이 생긴다고 하시니

그런 경우일지도 모르겠네요.

nand의 경우는 좀 늦어지는 경우는 있을 수 있습니다.

개인적인 경험으로는 주로 permission 문제가 많았습니다.

신현호님 고도리님...답변 진심으로 감사드립니다..

우선 오드로이드를 확인해본결과

E/WifiHW ( 825): Unable to open connection to supplicant on "/data/system/wpa_supplicant/eth0": No such file or directory

이 메세지는 동일하게 발생됩니다.

신현호님...

말씀하신것을 해보려면 어느 부분을 수정해야 되는지요??

고도리님..

말씀하신것처럼 퍼미션이 문제일 수도 있다는 생각이듭니다.

그런데 도대체 퍼미션을 어떻게 주어야 하는지 모르겠습니다.

저는 nfs로 부팅후 mtd영역을 마운트해서 root.root로 변경하고 777로 변경하였습니다.
