4.Boot with the microSD without eMMC.

5.Turn on U2/U3 and wait a few seconds and blue LED will blink.

6.Plug your eMMC module into U2/U3

7.Plug micro-USB cable into U2/U3 and connect other side to your PC USB host or ODROID's USB host port.

  (This is a trigger to start the recovery)

8.After recovery process (only a few seconds), the blue LED will turn off automatically.

9.Finish. Install OS on your eMMC with as usual.

Case 2 : Boot from SD card and access the eMMC

2. Enter into the u-boot prompt by Enter key or Space key in 3 seconds.

3. Install the eMMC module on the board.

4. Issue a command to connect the eMMC.

Exynos4412 # movi init 1

5. Copy the boot code from SD to eMMC.

Exynos4412 # run copy_uboot_sd2emmc

6. Remove the SD card and power on with the eMMC. The Blue LED should be on by eMMC boot loader.
