   1 U-Boot for Amlogic SEI510
   2 =======================
   3
   4 SEI510 is a customer board manufactured by SEI Robotics with the following
   5 specifications:
   6
   7  - Amlogic S905X2 ARM Cortex-A53 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
  16 Currently the u-boot port supports the following devices:
  17  - serial
  18  - Ethernet
  19  - Regulators
  20  - Clock controller
  21
  22 u-boot compilation
  23 ==================
  24
  25  > export ARCH=arm
  26  > export CROSS_COMPILE=aarch64-none-elf-
  27  > make sei510_defconfig
  28  > make
  29
  30 Image creation
  31 ==============
  32
  33 Amlogic doesn't provide sources for the firmware and for tools needed
  34 to create the bootloader image, so it is necessary to obtain them from
  35 the git tree published by the board vendor:
  36
  37  > wget https://releases.linaro.org/archive/13.11/components/toolchain/binaries/gcc-linaro-aarch64-none-elf-4.8-2013.11_linux.tar.xz
  38  > wget https://releases.linaro.org/archive/13.11/components/toolchain/binaries/gcc-linaro-arm-none-eabi-4.8-2013.11_linux.tar.xz
  39  > tar xvfJ gcc-linaro-aarch64-none-elf-4.8-2013.11_linux.tar.xz
  40  > tar xvfJ gcc-linaro-arm-none-eabi-4.8-2013.11_linux.tar.xz
  41  > 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:$PATH
  42  > git clone https://github.com/BayLibre/u-boot.git -b buildroot-openlinux-20180418 amlogic-u-boot
  43  > cd amlogic-u-boot
  44  > make g12a_u200_v1_defconfig
  45  > make
  46  > export UBOOTDIR=$PWD
  47
  48 Download the latest Amlogic Buildroot package, and extract it :
  49  > wget http://openlinux2.amlogic.com:8000/ARM/filesystem/Linux_BSP/buildroot_openlinux_kernel_4.9_fbdev_20180706.tar.gz
  50  > tar xfz buildroot_openlinux_kernel_4.9_fbdev_20180706.tar.gz buildroot_openlinux_kernel_4.9_fbdev_20180706/bootloader
  51  > export BRDIR=$PWD/buildroot_openlinux_kernel_4.9_fbdev_20180706
  52  > export FIPDIR=$BRDIR/bootloader/uboot-repo/fip
  53
  54 Go back to mainline U-Boot source tree then :
  55  > mkdir fip
  56
  57  > wget https://github.com/BayLibre/u-boot/releases/download/v2017.11-libretech-cc/blx_fix_g12a.sh -O fip/blx_fix.sh
