The SEI510 board is based on the Amlogic S905X2 SoC from the Amlogic G12A SoC family. The board has the following specifications : - Amlogic S905X2 ARM Cortex-A53 quad-core SoC - XGB DDR4 SDRAM - 10/100 Ethernet (Internal PHY) - 1 x USB 3.0 Host - eMMC - SDcard - Infrared receiver - SDIO WiFi Module The board default behaviour is for booting Android and triggers fastboot on recovery or reboot mode. USB vendor ID (used by fastboot) is 0x18d1 (Google) for default udev rules for existing android users work out of the box.

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-aarch64-none-elf-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
