현재 MMC를 제작해서 테스트중인데 32MB MMC카드(SANDISK)로 테스트할떄는
문제없이 잘 마운트되고 읽고 쓰기가 되는거 확인했는데
512M SD카드(SANDISK)로 테스트를 해보니 마운트가 되지않습니다.
게시판 글을 보니 512M 까지는 되는걸로 알고있는데....
SD카드랑 MMC랑 명령어가 틀린가요???
[root@ez-x5 /root]$ mount -t vfat /dev/mmca1 /mnt/mmc/
mount: Mounting /dev/mmca1 on /mnt/mmc failed: No such device

mke2fs: No such device while trying to determine filesystem size
[root@ez-x5 /root]$ fdisk /dev/mmca
Unable to open /dev/mmca
SD카드는 fat으로 포멧했고 mknod /dev/mmca0 b 241 0 노드도 만들어줬고
커널도 수정해서 다 체크했습니다..
뭐가 문제인가요 도와주세요~~~
