6 Make ,you can add V=s to see more message ,also add -j4 to use quad core to work .
make
when compile finish bin/sunxi/ dir have a image，file name：openwrt-sunxi-BPI-XX-sdcard-vfat-ext4.img，i compile is BPI-
R1，so name is ：openwrt-sunxi-BPI-R1-sdcard-vfat-ext4.img，
7, use USB Image Tool(http://www.alexpage.de/) burn image to sd，insert BPI and booting it.
8 running ：
