찾아보니.. eMMC는 부트영역이 따로 설정되서 그냥은 못 건드리니
uboot에서 명령을 통해서 설정해야 하는 듯?
일단 SD 메모리만 꽂고(eMMC가 부팅 우선순위를 가지니)
1. 복구 이미지를 SD에 구워서 부팅후 eMMC를 꽂으면 복구
2. uart를 이용해서 uboot에서 "movi init 1" 와 "run copy_uboot_sd2emmc"명령을 통해 복구
Case 1: Using the Recovery image 1.Download Recovery Image file. 2.Unzip with 7-Zip (Windows) or Linux using “xz -d” 3.Prepare a microSD card and flash the attached image. flashing → refer this link 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 You need the USB-UART and serial terminal program like a Putty. 1. Boot the board with a Ubuntu SD Card without 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.

링크도 깨져있고..XU4용은 안드로이드고..
그냥 eMMC 구매하는건 포기할까?
웬지 이걸써서 라즈베리에서 SD 리더용 어댑터로 부팅이 안될거 같은데..
