4S400 is a reference board manufactured by Amlogic with the following
5specifications:
6
7 - Amlogic A113DX ARM Cortex-A53 quad-core SoC @ 1.2GHz
8 - 1GB DDR4 SDRAM
9 - 10/100 Ethernet
10 - 2 x USB 2.0 Host
11 - eMMC
12 - Infrared receiver

31u-boot compilation
32==================
33
34 > export ARCH=arm
35 > export CROSS_COMPILE=aarch64-none-elf-
36 > make s400_defconfig
37 > make

39Image creation
40==============
41
42Amlogic doesn't provide sources for the firmware and for tools needed
43to create the bootloader image, so it is necessary to obtain them from
44the git tree published by the board vendor:

54 > make
55 > export FIPDIR=$PWD/fip

57Go back to mainline U-boot source tree then :
58 > mkdir fip
59
60 > cp $FIPDIR/axg/bl2.bin fip/
61 > cp $FIPDIR/axg/acs.bin fip/
62 > cp $FIPDIR/axg/bl21.bin fip/

106and then write the image to SD with:
107
108 > DEV=/dev/your_sd_device
109 > dd if=fip/u-boot.bin.sd.bin of=$DEV conv=fsync,notrunc bs=512 skip=1 seek=1
110 > dd if=fip/u-boot.bin.sd.bin of=$DEV conv=fsync,notrunc bs=1 count=444
