   1 U-Boot for Amlogic Q200
   2 =======================
   3
   4 Q200 is a reference board manufactured by Amlogic with the following
   5 specifications:
   6
   7  - Amlogic S912 ARM Cortex-A53 octo-core SoC @ 1.5GHz
   8  - ARM Mali T860 GPU
   9  - 2/3GB DDR4 SDRAM
  10  - 10/100/1000 Ethernet
  11  - HDMI 2.0 4K/60Hz display
  12  - 2 x USB 2.0 Host, 1 x USB 2.0 Device
  13  - 16GB/32GB/64GB eMMC
  14  - 2MB SPI Flash
  15  - microSD

  30 U-Boot compilation
  31 ==================
  32
  33  > export CROSS_COMPILE=aarch64-none-elf-
  34  > make khadas-vim2_defconfig
  35  > make
  36
  37 Image creation
  38 ==============
  39
  40 Amlogic doesn't provide sources for the firmware and for tools needed
  41 to create the bootloader image, so it is necessary to obtain them from
  42 the git tree published by the board vendor:
  43
  44  > wget https://releases.linaro.org/archive/13.11/components/toolchain/binaries/gcc-linaro-aarch64-none-elf-4.8-2013.11_linux.tar.xz

  48  > 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:$PATH
  49  > git clone https://github.com/BayLibre/u-boot.git -b n-amlogic-openlinux-20170606 amlogic-u-boot
  50  > cd amlogic-u-boot
  51  > make gxm_q200_v1_defconfig
  52  > make
  53  > export FIPDIR=$PWD/fip
  54
  55 Go back to mainline U-Boot source tree then :
  56  > mkdir fip
  57
  58  > cp $FIPDIR/gxl/bl2.bin fip/
  59  > cp $FIPDIR/gxl/acs.bin fip/
  60  > cp $FIPDIR/gxl/bl21.bin fip/

  84         bl2
  85
  86  > $FIPDIR/gxl/aml_encrypt_gxl --bl3enc --input fip/bl30_new.bin
  87  > $FIPDIR/gxl/aml_encrypt_gxl --bl3enc --input fip/bl31.img
  88  > $FIPDIR/gxl/aml_encrypt_gxl --bl3enc --input fip/bl33.bin

  95                 --bl33 fip/bl33.bin.enc
  96
  97 and then write the image to SD with:
  98
  99  > DEV=/dev/your_sd_device
 100  > dd if=fip/u-boot.bin.sd.bin of=$DEV conv=fsync,notrunc bs=512 skip=1 seek=1
 101  > dd if=fip/u-boot.bin.sd.bin of=$DEV conv=fsync,notrunc bs=1 count=444
