해결했습니다. 제가 문서를 더 자세히 봤어야 했는데...
커널 소스를 root filesystem 안에 넣어두셨더군요.
-----------------------
좀 늦은 감도 있고, 너무 단순한 질문인지도 모르겠습니다만...
보드는 잘 받았고, U-boot는 보드에 올려져 있던 것을 그대로 쓰고,
aesop_mp2530f_kernel_bootloader.tar.gz를 압축을 풀고,
U-boot와 커널을 컴파일 하였습니다. 컴파일러는 개인적으로 buildroot를 이용해서 만든
컴파일러를 썼고, 그래서 그런지 u-boot 컴파일이 성공적으로 모두 끝나지는 않았지만, mkimage는 잘 생성이 되어서, 이를 /usr/bin에 설치한 뒤, 커널을 컴파일하였습니다.
커널은 잘 컴파일되었고, U-boot로부터 tftp로 잘 받아서 부팅이 되고 있습니다.
궁금한 사항은, U-boot에서 tftp로 잘 되는 네트워크가 커널이 부팅해서는 NFS로 root mount를 못하고 있습니다. 로그를 보니, 커널이 아예 네트워크 카드를 인식하지 못하는 것 같습니다.
- aesop-mp2530f의 ethernet chip이 SMC91111이 맞습니까?
- 그렇다면, 커널 menuconfig에서 Device Drivers --> Network device support --> Ethernet (100M) --> SMC 91C9x 를 선택하면 되는 건가요?
처음 커널 소스를 풀어서 make menuconfig 할 때에는 CS89x0가 선택되어 있더군요.
물론, 이걸 선택해도 네트워크가 되지 않는 건 마찬가지구요.
U-boot에서 TFTP가 잘 되는 걸로 봐서, H/W적으로 문제가 있어보이지는 않는데요.
어디가 문제인지 혹시 알려주시면 감사하겠습니다.
