   2 =======================
   3
   4 S400 is a reference board manufactured by Amlogic with the following
   5 specifications:
   6
   7  - Amlogic A113DX ARM Cortex-A53 quad-core SoC @ 1.2GHz
   8  - 1GB DDR4 SDRAM
   9  - 10/100 Ethernet
  10  - 2 x USB 2.0 Host
  11  - eMMC
  12  - Infrared receiver
  13  - SDIO WiFi Module
  14  - MIPI DSI Connector
  15  - Audio HAT Connector
  16  - PCI-E M.2 Connectors
  17
  18 Schematics are available from Amlogic on demand.
  19
  20 Currently the u-boot port supports the following devices:
  21  - serial
  22  - eMMC
  23  - Ethernet
  24  - I2C
  25  - Regulators
  26  - Reset controller
  27  - Clock controller
  28  - USB Host
  29  - ADC
  30
  31 u-boot compilation
  32 ==================
  33
  34  > export CROSS_COMPILE=aarch64-none-elf-
  35  > make s400_defconfig
  36  > make
  37
  38 Image creation
  39 ==============
  40
  41 Amlogic doesn't provide sources for the firmware and for tools needed
  42 to create the bootloader image, so it is necessary to obtain them from
  43 the git tree published by the board vendor:
  44
  45  > wget https://releases.linaro.org/archive/13.11/components/toolchain/binaries/gcc-linaro-aarch64-none-elf-4.8-2013.11_linux.tar.xz

  50  > git clone https://github.com/BayLibre/u-boot.git -b n-amlogic-openlinux-20170606 amlogic-u-boot
  51  > cd amlogic-u-boot
  52  > make axg_s400_v1_defconfig
  53  > make
  54  > export FIPDIR=$PWD/fip
  55
  56 Go back to mainline U-boot source tree then :

 105 and then write the image to SD with:
 106
 107  > DEV=/dev/your_sd_device
