1. Copy EMMC image to a running system which is on SD card
2. start system and look which mmcblk is the emmc: cat /proc/partitions (search for boot0 and this mmcblk [0|1] is the emmc)
3. flash EMMC image to User Data Area of EMMC: dd if=mtk-bpi-r2-EMMC.img of=/dev/mmcblkX
4. Unlock EMMC boot0 block: echo 0 > /sys/block/mmcblkXboot0/force_ro
5. flash preloader to EMMC boot0 block: dd if=mtk-bpi-r2-EMMC.img of=/dev/mmcblkXboot0 bs=1M count=1
6. Change the Partition configurion of EMMC to 48h: reboot the system which is running from SD, and enter the U-boot-console, run command “emmc pconf 48”
7. Power off, remove SD card, and then power on R2 board.
