   2 ====================
   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

  16
  17 Schematics are available on the manufacturer website.
  18
  19 Currently the u-boot port supports the following devices:
  20  - serial

  22  - Ethernet
  23
  24 u-boot compilation
  25 ==================
  26
  27  > export ARCH=arm
  28  > export CROSS_COMPILE=aarch64-none-elf-
  29  > make nanopi-k2_defconfig
  30  > make
  31
  32 Image creation
  33 ==============
  34
  35 Amlogic doesn't provide sources for the firmware and for tools needed
  36 to create the bootloader image, so it is necessary to obtain them from
  37 the git tree published by the board vendor:

  49  > make nanopi-k2_defconfig
  50  > make
  51  > export FIPDIR=$PWD/fip
  52
  53 Go back to mainline U-Boot source tree then :
  54  > mkdir fip
  55

  96 and then write the image to SD with:
