   3
   4 NanoPi-K2 is a single board computer manufactured by FriendlyElec
   5 with the following specifications:
   6
   7  - Amlogic S905 ARM Cortex-A53 quad-core SoC @ 1.5GHz
   8  - ARM Mali 450 GPU
   9  - 2GB DDR3 SDRAM
  10  - Gigabit Ethernet
  11  - HDMI 2.0 4K/60Hz display
  12  - 40-pin GPIO header
  13  - 4 x USB 2.0 Host, 1 x USB OTG

  22  - Ethernet
  23
  24 u-boot compilation
  25 ==================
  26
  27  > export CROSS_COMPILE=aarch64-none-elf-
  28  > make nanopi-k2_defconfig
  29  > make
  30
  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:

  50  > export FIPDIR=$PWD/fip
  51
  52 Go back to mainline U-Boot source tree then :
  53  > mkdir fip
