  30 U-Boot compilation
  31 ==================
  32
  33  > export ARCH=arm
  34  > export CROSS_COMPILE=aarch64-none-elf-
  35  > make libretech-cc_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

  48  > tar xvfJ gcc-linaro-arm-none-eabi-4.8-2013.11_linux.tar.xz
  49  > 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:$PATH
  50  > git clone https://github.com/BayLibre/u-boot.git -b libretech-cc amlogic-u-boot
  51  > cd amlogic-u-boot
  52  > make libretech_cc_defconfig
  53  > make
  54  > export FIPDIR=$PWD/fip
  55
  56 Go back to mainline U-Boot source tree then :
  57  > mkdir fip
  58
  59  > cp $FIPDIR/gxl/bl2.bin fip/
  60  > cp $FIPDIR/gxl/acs.bin fip/

  83         fip/bl21_zero.bin \
  84         fip/bl2_new.bin \
  85         bl2
  86
  87  > $FIPDIR/gxl/aml_encrypt_gxl --bl3enc --input fip/bl30_new.bin
  88  > $FIPDIR/gxl/aml_encrypt_gxl --bl3enc --input fip/bl31.img
  89  > $FIPDIR/gxl/aml_encrypt_gxl --bl3enc --input fip/bl33.bin

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