안녕하세여 ~. 지난번에 이와 같은 디바이스 드라이버에 대해서 커널 패닉이 있었는데... 아직도 못잡고 있네여 에휴 ㅠ.ㅠ
이와 관련 해서 몇가지 여쭈어보고자 합니다.
1. SMC91111과 SMC91c113의 데이터 시트를 분석해 봤는데, 버스 엑세스가 16bit 방식에서 32bit 방식이 추가된거 말고는 없더군여. 해서 고현철님께서 제공하신 SMC91C113의 소스를 바탕으로 32bit data bus 방식으로 사용하게끔 소스를 수정했습니다. 물론 BWSON의 설정 또한 UB/LB를 사용하고, no wait, 32bit 방식으로 수정을 하였고, BANKCON 부분 또한 HCLK이 100Mhz일 때 각각을 맞추었습다. 아래가 제가 펌웨어로 테스트 했을 때, 설정 방식이였습니다.
HCLK 기준 (at 100MHz)
Tacs : Address set-up time before nGCSn
0x0 : 0 clock
Tcos : Chip selection set-up time before nOE
0x1 : 1 clock
Tacc : Access cycle
0x2 : 3 clock
Tcoh : Chip selection hold time after nOE
0x0 : 0 clock
Tcah : Address hold time after nGCSn
0x0 : 0 clock
Tacp : Page mode access cycle @ Page mode
0x0 : 2 clock
PMC : Page Mode Configuration
0x0 : normal (1 data)
위와 같은 설정을 다 맞추고 smc91x.h의 s3c2440의 세팅에서 ioctl 함수 부분을 8/16/32bit에 맞게 다 수정하고 올렸더니...커널패닉..ㅡㅡ;;; 정말 이걸로 한달 정도 고생하는거 같네여...제가 가지고 있는 리눅스 책 다 디집어 봤지만, 내공이 부족한듯합니다. 부디 따가운 조언 부탁드립니다.
2. 혹시 아래와 같이 nfs 부팅을 할 때, 정말 몰라서 묻는건데...저 방법이 가장 좋은 방법인가여? 램디스크 부터 해야할지...네트워크 디바이스 드라이버를 초기화하지 않고 다른 방법은 없는건가여? 개발 순서를 어떻게 잡아야할지 모르겠습니다....저도 팽귄을 띄우고 싶습니다..ㅡㅡ;; 고수님들의 개발 순서를 알려주셨으면 좋겠습다.
3. 이 글을 읽어주셔서 고맙습니다...잘되면 밥이라도 쏠께여, 술도 좋고..;;; 부디 읽어주셨으면, 아무거라도 좋으니 질책 부탁드리겠습니다. 아래는 제 커널 패닉 메시지 입니다.

network를 테스트할 경우는
1. ramdisk 사용해서 드라이버를 나중에 올린다.
2. NFS로 직접 테스트해본다...
2번의 경우는 한번에 잡는 케이스인데, 보통은 1번부터 하는겁니다.

system.map 파일에서 LR 레지스터에 해당하는 번지를 찾으신 후
어느 함수에서 crash가 났는지 파악하시기 바랍니다.
