  22 U-Boot Compilation
  23 ------------------
  24
  25 .. code-block:: bash
  26
  27     $ export CROSS_COMPILE=aarch64-none-elf-
  28     $ make w400_defconfig
  29     $ make
  30
  31 U-Boot Signing with Pre-Built FIP repo
  32 --------------------------------------
  33
  34 .. code-block:: bash
  35
  36     $ git clone https://github.com/LibreELEC/amlogic-boot-fip --depth=1
  37     $ cd amlogic-boot-fip
  38     $ mkdir my-output-dir
  39     $ ./build-fip.sh jethub-j100 /path/to/u-boot/u-boot.bin my-output-dir

  41 U-Boot Manual Signing
  42 ---------------------
  43
  44 Amlogic does not provide sources for the firmware and tools needed to create a bootloader
  45 image so it is necessary to obtain binaries from sources published by the board vendor:
  46
  47 .. code-block:: bash
  48
  49     $ wget https://releases.linaro.org/archive/13.11/components/toolchain/binaries/gcc-linaro-aarch64-none-elf-4.8-2013.11_linux.tar.xz
  50     $ wget https://releases.linaro.org/archive/13.11/components/toolchain/binaries/gcc-linaro-arm-none-eabi-4.8-2013.11_linux.tar.xz
  51     $ tar xvfJ gcc-linaro-aarch64-none-elf-4.8-2013.11_linux.tar.xz
  52     $ tar xvfJ gcc-linaro-arm-none-eabi-4.8-2013.11_linux.tar.xz
  53     $ export PATH=$PWD/gcc-linaro-aarch64-none-elf-4.8-2013.11_linux/bin:$PWD/gcc-linaro-arm-none-eabi-4.8-2013.11_linux/bin:$PATH
  54     $ git clone https://github.com/BayLibre/u-boot.git -b buildroot-openlinux-20180418 amlogic-u-boot
  55     $ cd amlogic-u-boot
  56     $ make g12b_w400_v1_defconfig
  57     $ make
  58     $ export UBOOTDIR=$PWD
  59
  60 Download the latest Amlogic buildroot package and extract it:
  61
  62 .. code-block:: bash
  63
  64     $ wget http://openlinux2.amlogic.com:8000/ARM/filesystem/Linux_BSP/buildroot_openlinux_kernel_4.9_fbdev_20180706.tar.gz
  65     $ tar xfz buildroot_openlinux_kernel_4.9_fbdev_20180706.tar.gz buildroot_openlinux_kernel_4.9_fbdev_20180706/bootloader
  66     $ export BRDIR=$PWD/buildroot_openlinux_kernel_4.9_fbdev_20180706
  67     $ export FIPDIR=$BRDIR/bootloader/uboot-repo/fip
  68
  69 Go back to the mainline U-Boot source tree then:
