Summary
=======

This README is about U-Boot support for SAMSUNG's/NEXELL's ARM Cortex-A9 based
S5P4418 SoC. It is based on FriendlyARM's U-Boot v2016.01 for the NanoPi2
(and other) boards [1].

Currently the following boards are supported:

* FriendlyArm NanoPi2   [2]
* FriendlyArm NanoPC-T2 [3]


Build
=====

* NanoPi2 and NanoPC-T2

make s5p4418_nanopi2_defconfig
make


Installation
============

- Download Official-ROMs-SDCard-20190718.7z from [4] (images files for android,
  friendlyCore and LUbuntu)
- Use s5p4418-sd-lubuntu-desktop-xenial-4.4-armhf-20190718.img to make a SD-card
- Use dd in the directory where U-Boot has been built to update U-Boot:
  (replace <SD-card> with the device used for the SD-card, e.g. sdc)
  sudo dd seek=3841 if=u-boot.bin of=/dev/<SD-card>
- Boot the board from this SD-card

The source code for (the used?) LUbuntu 16.04 can be found at [5].
