위 사항을 적용한 다음에 새롭게 컴파일하여 생성된 이미지를 보드에 write합니다.

이때 “fdisk”설정은 다음과 같이 진행하시길 바랍니다.

MV4412 # fdisk -c 0 700 2400 500

Count: 10000

NAME: S5P_MSHC4

fdisk is completed

partion #    size(MB)     block start #    block count    partition_Id

   4           501          6491463         1027752          0x83

새롭게 이미지를 적용한 후에 부팅을 하시면 아래와 같이 설정 된 것을 확인 하실 수 있습니다.
