   1 U-Boot for Amlogic W400
   2 =======================
   3
   4 U200 is a reference board manufactured by Amlogic with the following
   5 specifications:
   6
   7  - Amlogic S922X ARM Cortex-A53 dual-core + Cortex-A73 quad-core SoC
   8  - 2GB DDR4 SDRAM
   9  - 10/100 Ethernet (Internal PHY)
  10  - 1 x USB 3.0 Host
  11  - eMMC
  12  - SDcard
  13  - Infrared receiver
  14  - SDIO WiFi Module
  15  - MIPI DSI Connector
  16  - Audio HAT Connector
  17  - PCI-E M.2 Connector
  18
  19 Schematics are available from Amlogic on demand.
  20
  21 Currently the u-boot port supports the following devices:
  22  - serial
  23  - Ethernet
  24  - Regulators
  25  - Clock controller
  26
  27 u-boot compilation
  28 ==================
  29
  30  > export ARCH=arm
  31  > export CROSS_COMPILE=aarch64-none-elf-
  32  > make w400_defconfig
  33  > make
  34
  35 Image creation
  36 ==============
  37
  38 Amlogic doesn't provide sources for the firmware and for tools needed
  39 to create the bootloader image, so it is necessary to obtain them from
  40 the git tree published by the board vendor:
  41
  42  > wget https://releases.linaro.org/archive/13.11/components/toolchain/binaries/gcc-linaro-aarch64-none-elf-4.8-2013.11_linux.tar.xz
  43  > wget https://releases.linaro.org/archive/13.11/components/toolchain/binaries/gcc-linaro-arm-none-eabi-4.8-2013.11_linux.tar.xz

  45  > tar xvfJ gcc-linaro-arm-none-eabi-4.8-2013.11_linux.tar.xz
  46  > 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:$PATH
  47  > git clone https://github.com/BayLibre/u-boot.git -b buildroot-openlinux-20180418 amlogic-u-boot
  48  > cd amlogic-u-boot
  49  > make g12b_w400_v1_defconfig
  50  > make
  51  > export UBOOTDIR=$PWD
  52
  53 Download the latest Amlogic Buildroot package, and extract it :
  54  > wget http://openlinux2.amlogic.com:8000/ARM/filesystem/Linux_BSP/buildroot_openlinux_kernel_4.9_fbdev_20180706.tar.gz
  55  > tar xfz buildroot_openlinux_kernel_4.9_fbdev_20180706.tar.gz buildroot_openlinux_kernel_4.9_fbdev_20180706/bootloader
  56  > export BRDIR=$PWD/buildroot_openlinux_kernel_4.9_fbdev_20180706
  57  > export FIPDIR=$BRDIR/bootloader/uboot-repo/fip
  58
  59 Go back to mainline U-Boot source tree then :
