  22
  23 u-boot compilation
  24 ==================
  25
  26  > export ARCH=arm
  27  > export CROSS_COMPILE=aarch64-none-elf-
  28  > make odroid-c2_defconfig
  29  > make

  31 Image creation
  32 ==============
  33
  34 Amlogic doesn't provide sources for the firmware and for tools needed
  35 to create the bootloader image, so it is necessary to obtain them from
  36 the git tree published by the board vendor:
  37
  38  > DIR=odroid-c2
  39  > git clone --depth 1 \
  40        https://github.com/hardkernel/u-boot.git -b odroidc2-v2015.01 \
  41        $DIR
  42  > $DIR/fip/fip_create --bl30  $DIR/fip/gxb/bl30.bin \
  43                        --bl301 $DIR/fip/gxb/bl301.bin \
  44                        --bl31  $DIR/fip/gxb/bl31.bin \
  45                        --bl33  u-boot.bin \
  46                        $DIR/fip.bin
  47  > $DIR/fip/fip_create --dump $DIR/fip.bin
  48  > cat $DIR/fip/gxb/bl2.package $DIR/fip.bin > $DIR/boot_new.bin
  49  > $DIR/fip/gxb/aml_encrypt_gxb --bootsig \
  50                                 --input $DIR/boot_new.bin \
  51                                 --output $DIR/u-boot.img
  52  > dd if=$DIR/u-boot.img of=$DIR/u-boot.gxbb bs=512 skip=96
  53
  54 and then write the image to SD with:
  55
  56  > DEV=/dev/your_sd_device
  57  > BL1=$DIR/sd_fuse/bl1.bin.hardkernel
  58  > dd if=$BL1 of=$DEV conv=fsync bs=1 count=442
  59  > dd if=$BL1 of=$DEV conv=fsync bs=512 skip=1 seek=1
  60  > dd if=$DIR/u-boot.gxbb of=$DEV conv=fsync bs=512 seek=97
