-Firefly RK3288
-
-How to build it
-===============
-
-  $ make firefly_rk3288_defconfig
-
-Then you can edit the build options using
-
-  $ make menuconfig
-
-Compile all and build rootfs image:
-
-  $ make
-
-Result of the build
--------------------
-
-After building, you should get a tree like this:
-
-  output/images/
-  ??? rk3288-firefly.dtb
-  ??? rootfs.ext2
-  ??? rootfs.ext4 -> rootfs.ext2
-  ??? sdcard.img
-  ??? u-boot-dtb.img
-  ??? u-boot-spl-dtb.bin
-  ??? u-boot-spl-dtb.img
-  ??? uImage
-
-Prepare your SDCard
-===================
-
-Buildroot generates a ready-to-use SD card image that you can flash directly to
-the card. The image will be in output/images/sdcard.img.
-You can write this image directly to an SD card device (i.e. /dev/xxx):
-
-  $ dd if=output/images/sdcard.img of=/dev/xxx
-
-Finally, you can insert the SD card to the Firefly RK3288 board and boot it.
