+BeagleBone
+
+Intro
+=====
+To be able to use BeagleBone board with the images generated by
+Buildroot, you have to prepare the SDCard.
+
+How to build it
+===============
+
+  $ make beaglebone_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/
+  ├── am335x-boneblack.dtb
+  ├── am335x-bone.dtb
+  ├── MLO
+  ├── rootfs.ext2
+  ├── u-boot.img
+  ├── uEnv.txt
+  └── zImage
+
+
+Prepare your SDCard
+===================
+
+You need to prepare first partition in fat32 and marked as bootable,
+and second where you will write rootfs.
+
+Copy the files to boot partition
+
+  $ cp MLO u-boot.img zImage uEnv.txt *.dtb /media/zzzzz
+
+where /media/zzzzz is the mount point.
+Then you need to write the rootfs image onto SDCard:
+
+  # dd if=rootfs.ext2 of=/dev/xxxxx
+
+where /dev/xxxxx is the second partition. Use:
+
+  # fdisk -l
+
+to check for correct one.
+
+Finish
+======
+
+Unmount all mounted SDCard partitions and insert the card to BeagleBone.
+Hold the "BOOT" button and apply power. Then release the "BOOT" button.
+The output is available on the serial console.
