Nor에 파티션까지 설정이 되었네요...
uboot 파티션을 512k로 하고 커널은 1.3M 정도라서 나머지를 커널로 파티션을 잡았습니다..
그러면 2M안에 uboot와 kernel이 딱 들어가겠네요...

그리고 nand일때는
nand write 32000000 0 커널사이즈
setenv bootcmd nand read 32000000 0 1FFFFF ;bootm 32000000
이렇게 해주면 되는데 nor일때는 setenv 설정을 어떻게 해줘야 하는지
찾아봐도 없는거 같아서 질문 드립니다........
uboot 명령으로 가능한 것인지 아니면 uboot에서 좀 수정을 해줘야 하는건지요...
nor에 부트로더와 커널을 올리고 nand에 rootfs를 올려볼려고 합니다...

nor에 부트로더와 커널을 올리고 nand에 rootfs를 올려볼려고 합니다...
왜냐하면, NOR 2M중 맨 마지막 블럭은 u-boot의 환경변수로
사용이 됩니다.
해서 u-boot를 고쳐서 환경변수 영역을 u-boot가 올라간 위치 다음에서
사용이 되도록 하거나, 아니면 mtd영역을 세개로 쪼개야 합니다.
잘 못 하다가는 환경변수 영역을 싸그리 밀어버리는 현상이 발생할 겁니다.
그리고, 커널도 위와같은 방법으로 하는게 맞습니다.
nand에 rootfs를 올릴때는 nfs로 부팅한 후 flash erase해주고, yaffs로 마운트 한 후 쓰시면 됩니다.
아닐 경우는 좀 복잡한데, 이유는 nand의 bad처리때문입니다.
