추가 : 일단 조금은 더 진행했습니다
램디스크 크기와 bootargs의 ramdisk_size를 똑같이 맞추니 일단 좀 더 진행은 되네요

이렇게 멈추네요
/dev/mtdblock1 마운트를 시도 하는거 같은데 좀더 살펴봐야 겠습니다
계속 질문이 추가 되서 죄송합니다^^
그리고 감사합니다 즐거운 하루 되세요~
---------------------------------------------------------------------------------------------------------------------
사용보드는 AM3517 커스텀 보드입니다 메모리는 MT47H64M16HR 2개가 달려 있습니다
(데이터시트 : http://www.micron.com/~/media/documents/products/data-sheet/dram/ddr2/1gb_ddr2.pdf)
리눅스 버전은 2.6.37입니다
일단
dd if=/dev/zero of=ramdisk bs=1M count=100 으로 100M의 램디스크를 만들고
mke2fs ramdisk 로 ext2 로 포맷했습니다
mount -o loop ramdisk /ramfs/ 를 마운트 해서 기존에 만들어져 있던 폴더를 전부 복사했습니다
umount /ramfs 로 마운트를 해제하고
gzip ramdisk 로 압축을 했습니다
mkimage -n 'Ramdisk' -A arm -O linux -T ramdisk -C gzip -a 0x84000000 -e 0x84000000 -d ramdisk.gz ramdisk.img 명령으로 uboot 에서 불러 올수 있게 만든다음
u-boot 로 부팅후
tftp 0x82000000 uImage 로 커널이미지를 메모리에 다운받고
tftp 0x84000000 ramdisk.img 로 커널 이미지를 메모리에 다운받았습니다
그리고 bootm 0x82000000 0x84000000 로 부팅을 했습니다
그럼 아래와 같은 로그처럼 뜨네요
(처음엔 램디스크를 찾을수 없다고 하더니 위의 mkimage 만들때 주소를 램디스크 올리는 메모리 주소 0x84000000로 바꾸니 아래처럼 램디스크를 찾을수 없다는 말은 안나오네요
근데 또 mkimage 안한 파일을 넣으면 파일이 잘못됐다는 말이 나오고요ㅠㅠ)
setenv bootargs 'root=/dev/ram0 rw initrd=0x84000000,50M ramdisk_size=48231164 mem=256M console=ttyO2,115200n8'
설정은 위와 같이 했습니다 여기서 궁금한게 만든 ramdisk.img 파일 용량이 48231164 이면 위에서 ramdisk_size=48231164이 맞는 건가요?
그리고 그 앞으 50M는 뭘 의미하는지 궁금합니다
커널에서는 General Setup에서
Initial RAM filesystem and RAM disk (initramfs/initrd) support 와 Support initial ramdisks compressed using gzip를 활성화 시키고
Block Device에서 Default RAM disk size (kbytes)는 51200으로 해줬습니다(이 값을 잘못 넣으면 안되는건가요?)
혹시 잘못된 부분이나 빠트린 부분이 있나요?
파일시스템을 잘못 만든건지(기존에 ubifs 로 부팅 잘되던걸 그냥 복사만 했습니다)
yaffs2가 잘안되서 일단 램디스크로 먼저 해보자고 해서 하는데 역시 막히네요
뭐가 잘못됐는지 알수 있을까요?
혹시나 파일시스템이 잘못됐나 싶어 구글 검색해서 받아서 해봐도 똑같네요 ㅠㅠ
(고도리 님이 올리신것도 받아서 해봤습니다)
혹시 보드의 부트모드가 상관있나요?
감사합니다^^

참고하시고요.
부팅시 bootargs에는 initrd만 사용하시기 바랍니다.
initrd=0x84000000,50M
여기 지정된 size가 커널로 건너가는데, 만들어 놓은 ramdisk의 원래 크기와 같아야 합니다.
가장 좋은 것은
1. make menuconfig --> block device 의 ramdisk 크기를 32M 정도로 지정
2. bootloader의 bootargs 설정시 ramdisk를 1번에서와 같이 지정
하는게 제일 명확합니다.
