README 

U-Boot for Amlogic SEI510
=======================

SEI510 is a customer board manufactured by SEI Robotics with the following
specifications:

 - Amlogic S905X2 ARM Cortex-A53 quad-core SoC
 - 2GB DDR4 SDRAM
 - 10/100 Ethernet (Internal PHY)
 - 1 x USB 3.0 Host
 - eMMC
 - SDcard
 - Infrared receiver
 - SDIO WiFi Module

Currently the u-boot port supports the following devices:
 - serial
 - Ethernet
 - Regulators
 - Clock controller

u-boot compilation
==================

 > export ARCH=arm
 > export CROSS_COMPILE=aarch64-none-elf-
 > make sei510_defconfig
 > make

Image creation
==============

Amlogic doesn't provide sources for the firmware and for tools needed
to create the bootloader image, so it is necessary to obtain them from
the git tree published by the board vendor:

 > wget https://releases.linaro.org/archive/13.11/components/toolchain/binaries/gcc-linaro-aarch64-none-elf-4.8-2013.11_linux.tar.xz
 > wget https://releases.linaro.org/archive/13.11/components/toolchain/binaries/gcc-linaro-arm-none-eabi-4.8-2013.11_linux.tar.xz

 > tar xvfJ gcc-linaro-arm-none-eabi-4.8-2013.11_linux.tar.xz
 > export PATH=$PWD/gcc-linaro-aarch64-none-elf-4.8-2013.11_linux/bin:$PWD/gcc-linaro-arm-none-eabi-4.8-2013.11_linux/bin:$PATH
 > git clone https://github.com/BayLibre/u-boot.git -b buildroot-openlinux-20180418 amlogic-u-boot
 > cd amlogic-u-boot
 > make g12a_u200_v1_defconfig
 > make
 > export UBOOTDIR=$PWD

Download the latest Amlogic Buildroot package, and extract it :
 > wget http://openlinux2.amlogic.com:8000/ARM/filesystem/Linux_BSP/buildroot_openlinux_kernel_4.9_fbdev_20180706.tar.gz
 > tar xfz buildroot_openlinux_kernel_4.9_fbdev_20180706.tar.gz buildroot_openlinux_kernel_4.9_fbdev_20180706/bootloader
 > export BRDIR=$PWD/buildroot_openlinux_kernel_4.9_fbdev_20180706
 > export FIPDIR=$BRDIR/bootloader/uboot-repo/fip

Go back to mainline U-Boot source tree then :
 > mkdir fip

 > wget https://github.com/BayLibre/u-boot/releases/download/v2017.11-libretech-cc/blx_fix_g12a.sh -O fip/blx_fix.sh

and then write the image to SD with:

 > dd if=fip/u-boot.bin.sd.bin of=$DEV conv=fsync,notrunc bs=512 skip=1 seek=1
 > dd if=fip/u-boot.bin.sd.bin of=$DEV conv=fsync,notrunc bs=1 count=444
