어느정도 진전이 있는건지..^^;

[jjangbc]

커널은 2.4.18 에 부트로더는 u-boot 이고요.
패치는 물론 해준겁니다.
ramdisk 는 압축해서 7M, 압축 풀면 16M 정도 이고요.
아래는 부팅 메세지 인데요.
기존 소스에는 smc 가 64M 용으로 된거 같아서 16M 로 수정을 해주었고,
램디스크 4M 에서 용량 늘려준 정도 커널을 수정하였습니다.
부팅 메세지를 보면 일단은 smc 를 사용은 할수 있게끔 되있는거 같은데요. mtd 관련해서 좀더 수정을 해줘야될것 같네요.
커널 컴파일 할때 mtd 관련해서 설정 해줘야 되는 부분이 있는데,

미지 커널 과 linux-2.4.18(patch)이 좀 다르더군요.
좀 망막하긴 한데..그래도 조금씩이라도 나아지는거 같아서...하고 있습니다. 참고로 제가 이걸 할려고 하는 이유는요.
vivi 로 부팅을 하고 커널을 다운로드 하고 램디스크를 다운로드 하는데
(전부다 Jflash 로 download 하거든요) 시간이 9시간 정도 걸립니다.램디스크 싸이즈가 커서죠)그런데 ,u-boot 로 하면은 부트로더만 Jflash 로 하고 커널과 램디스크는 serial 로 하기때문에 1시간 정도도 안걸리죠..시간 단축을 위해서 하는 겁니다.^^.
두 작업 모두다 성공하게 되면 vivi, kernel, ramdisk (1 set)
u-boot, kernel, ramdisk (1set) 이렇게 자료실에 올려 놓도록 하죠^^
