===== SD =====

    dd if=mtk-bpi-r2-SD.img of=/dev/sdx


===== EMMC =====

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