SD FDisk

$ sudo fdisk /dev/mmcblk0

Welcome to fdisk (util-linux 2.29.2).
Changes will remain in memory only, until you decide to write them.
Be careful before using the write command.


Command (m for help): p
Disk /dev/mmcblk0: 29.8 GiB, 32010928128 bytes, 62521344 sectors
Units: sectors of 1 * 512 = 512 bytes

I/O size (minimum/optimal): 512 bytes / 512 bytes

Command (m for help): d
Partition number (1,2, default 2): 2

Partition 2 has been deleted.

Command (m for help): n

Last sector, +sectors or +size{K,M,G,T,P} (139264-62521343, default 62521343): 

Created a new partition 2 of type 'Linux' and of size 29.8 GiB.
Partition #2 contains a ext4 signature.

Do you want to remove the signature? [Y]es/[N]o: Y 

The signature will be removed by a write command.

Command (m for help): w
The partition table has been altered.
Calling ioctl() to re-read partition table.
Re-reading the partition table failed.: Device or resource busy

The kernel still uses the old table. The new table will be used at the next reboot or after you run partprobe(8) or kpartx(8).

이미지 복원

이미지 복원이 완료되면 SD 메모리를 제거하고 재부팅, eMMC 용량을 다 사용하지 않는 경우 eMMC 확장 필요
