HI:
you can follow it .
Step 1: Format your SD Card
Step 2: Put the file(s) to 100MB of the SD Card whit DD command.
sudo dd if=boot0_sdcard.fex of=/dev/sdb bs=1k seek=8
sudo dd if=u-boot.fex of=/dev/sdb bs=1k seek=16400
sudo dd if=sunxi_mbr.fex of=/dev/sdb bs=1k seek=20480
sudo dd if=boot-resource.fex of=/dev/sdb bs=1k seek=36864
sudo dd if=env.fex of=/dev/sdb bs=1k seek=69632
Step 3: Check console log:
