How to make Installer for ODROID-XU3

Insert microSD/eMMC to PC.
Check media node name.
$ sudo fdisk -l

Fill zero data to media.
$ sudo dd if=/dev/zero of=/dev/sdX bs=512 count=1024000

Run Gparted.
menu -> Device -> Create Partition Table...

menu -> Partition -> New

Free space preceding (MiB) 100

New size (MiB): 400

File system: fat32

Apply All Operations

fuse u-boot binaries for SD media.

https://github.com/codewalkerster/android_device_hardkernel_odroidxu3/tree/5422_4.4.4_master/uboot

$ cd device/hardkernel/odroidxu3/uboot

$ sudo sh sd_fusing.sd /dev/sdX

mount fat32 partition.

copy bl1.bin, bl2.bin, tzsw.bin, u-boot.bin files to mounted partition.

$ cd out/target/product/odroidxu3/update/

copy zImage-dtb, system.img, userdata.img, cache.ing to mounted partition.

copy boot.ini file too.

http://dn.odroid.com/5422/ODROID-XU3/Android/boot.ini/

sync and umount.

dump image.

$ sudo dd if=/dev/sdX of=./sd_installer.img bs=512 count=1024000

Extract img file and make checksum by md5sum.

How to recovery eMMC u-boot on ODROID

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.

eMMC 5.0

3. Exynos5422(ODROD-XU3/4)

Windows 사용자는 아래 링크에서 프로그램을 받아 씁니다.

http://com.odroid.com/sigong/nf_file_board/nfile_board_view.php?keyword=&tag=&bid=199

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.

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.
