  31 U-Boot compilation
  32 ==================
  33
  34  > export ARCH=arm
  35  > export CROSS_COMPILE=aarch64-none-elf-
  36  > make khadas-vim2_defconfig
  37  > make
  38
  39 Image creation
  40 ==============
  41
  42 Amlogic doesn't provide sources for the firmware and for tools needed
  43 to create the bootloader image, so it is necessary to obtain them from
  44 the git tree published by the board vendor:
  45
  46  > wget https://releases.linaro.org/archive/13.11/components/toolchain/binaries/gcc-linaro-aarch64-none-elf-4.8-2013.11_linux.tar.xz
  47  > wget https://releases.linaro.org/archive/13.11/components/toolchain/binaries/gcc-linaro-arm-none-eabi-4.8-2013.11_linux.tar.xz

  49  > tar xvfJ gcc-linaro-arm-none-eabi-4.8-2013.11_linux.tar.xz
  50  > 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:$PATH
  51  > git clone https://github.com/khadas/u-boot -b khadas-vim-v2015.01 vim-u-boot
  52  > cd vim-u-boot
  53  > make kvim2_defconfig
  54  > make
  55  > export FIPDIR=$PWD/fip
  56
  57 Go back to mainline U-Boot source tree then :
  58  > mkdir fip
  59
  60  > cp $FIPDIR/gxl/bl2.bin fip/
  61  > cp $FIPDIR/gxl/acs.bin fip/
  62  > cp $FIPDIR/gxl/bl21.bin fip/
  63  > cp $FIPDIR/gxl/bl30.bin fip/
  64  > cp $FIPDIR/gxl/bl301.bin fip/
  65  > cp $FIPDIR/gxl/bl31.img fip/

  72         fip/bl301.bin \
  73         fip/bl301_zero.bin \
  74         fip/bl30_new.bin \
  75         bl30
  76
  77  > python $FIPDIR/acs_tool.pyc fip/bl2.bin fip/bl2_acs.bin fip/acs.bin 0
  78
  79  > $FIPDIR/blx_fix.sh \
  80         fip/bl2_acs.bin \
  81         fip/zero_tmp \
  82         fip/bl2_zero.bin \
  83         fip/bl21.bin \
  84         fip/bl21_zero.bin \
  85         fip/bl2_new.bin \
  86         bl2
  87
  88  > $FIPDIR/gxl/aml_encrypt_gxl --bl3enc --input fip/bl30_new.bin
  89  > $FIPDIR/gxl/aml_encrypt_gxl --bl3enc --input fip/bl31.img
  90  > $FIPDIR/gxl/aml_encrypt_gxl --bl3enc --input fip/bl33.bin
  91  > $FIPDIR/gxl/aml_encrypt_gxl --bl2sig --input fip/bl2_new.bin --output fip/bl2.n.bin.sig
  92  > $FIPDIR/gxl/aml_encrypt_gxl --bootmk \
  93                 --output fip/u-boot.bin \

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