  23 U-Boot compilation
  24 ------------------
  25
  26 .. code-block:: bash
  27
  28     $ export CROSS_COMPILE=aarch64-none-elf-
  29     $ make u200_defconfig
  30     $ make
  31
  32 Image creation
  33 --------------
  34
  35 Amlogic doesn't provide sources for the firmware and for tools needed
  36 to create the bootloader image, so it is necessary to obtain them from
  37 the git tree published by the board vendor:
  38
  39 .. code-block:: bash
  40
  41     $ wget https://releases.linaro.org/archive/13.11/components/toolchain/binaries/gcc-linaro-aarch64-none-elf-4.8-2013.11_linux.tar.xz
  42     $ wget https://releases.linaro.org/archive/13.11/components/toolchain/binaries/gcc-linaro-arm-none-eabi-4.8-2013.11_linux.tar.xz

  46     $ git clone https://github.com/BayLibre/u-boot.git -b buildroot-openlinux-20180418 amlogic-u-boot

  48     $ make g12a_u200_v1_defconfig
  49     $ make
  50     $ export UBOOTDIR=$PWD
  51
  52 Download the latest Amlogic Buildroot package, and extract it :
  53
  54 .. code-block:: bash
  55
  56     $ wget http://openlinux2.amlogic.com:8000/ARM/filesystem/Linux_BSP/buildroot_openlinux_kernel_4.9_fbdev_20180706.tar.gz

  59     $ export FIPDIR=$BRDIR/bootloader/uboot-repo/fip
  60
