eMMC에 u-boot을 잘 못 fusing하거나 망가져 부팅 할 수 없을 때 복구 방법 또는 다른 제품의 eMMC를 구매 후 사용하는 방법
eMMC의 u-boot 영역은 sd 카드와 달리 PC 상에서 접근 할 수 없습니다.
그래서 eMMC의 u-boot을 복구 하기 위해서는 SD로 부팅 하여 eMMC의 u-boot 영역을 써야 합니다.

Windows 사용자는 아래 링크에서 프로그램을 받아 씁니다.
Linux 사용자들은 dd 명령으로 write합니다.
$ sudo dd if=./exynos4412_emmc_recovery_from_sd.img of=/dev/sdX
아래의 사진과 같이 sd 부팅으로 스위치를 바꾸고 전원을 넣으면 자동 복구 합니다.

ODROID-XU3/LITE
수동으로 u-boot만 복구하려면 부팅 후 USB-UART Module Kit을 연결하고 u-boot prompt에서 pri를 입력해 봅니다.

아래의 스크립트를 실행하면 자동으로 4개의 bin을 fusing합니다.
$ ./emmc_fastboot_fusing.sh
$ fastboot reboot
ODROID-Q/Q2는 아래 이미지를 받아 sd에 write합니다.

sd를 연결하고 스위치를 사진과 같이 하시면 sd로 부팅이 됩니다. 동일하게 eMMC를 복구 하시면 됩니다.
2.2 자동으로 복구 하기
포럼에 설명이 잘되어 있습니다.http://forum.odroid.com/viewtopic.php?f=53&t=969
복구용 sd 이미지를 다운 받습니다.

Linux 사용자들은 dd 명령으로 write합니다.
$ sudo dd if=./exynos4412_emmc_recovery_from_sd.img of=/dev/sdX
sd를 꼽고 eMMC를 제거한고 전원을 넣습니다.
