U-Boot for Amlogic W400
|
||
|
|
=======================
|
||
|
|
|
||
|
|
U200 is a reference board manufactured by Amlogic with the following
|
||
|
|
specifications:
|
||
|
|
|
||
|
|
- Amlogic S922X ARM Cortex-A53 dual-core + Cortex-A73 quad-core SoC
|
||
|
|
- 2GB DDR4 SDRAM
|
||
|
|
- 10/100 Ethernet (Internal PHY)
|
||
|
|
- 1 x USB 3.0 Host
|
||
|
|
- eMMC
|
||
|
|
- SDcard
|
||
|
|
- Infrared receiver
|
||
|
|
- SDIO WiFi Module
|
||
|
|
- MIPI DSI Connector
|
||
|
|
- Audio HAT Connector
|
||
|
|
- PCI-E M.2 Connector
|
||
|
|
|
||
|
|
Schematics are available from Amlogic on demand.
|
||
|
|
|
||
|
|
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 w400_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:$PATH
|
||
|
|
> git clone https://github.com/BayLibre/u-boot.git -b buildroot-openlinux-20180418 amlogic-u-boot
|
||
|
|
> cd amlogic-u-boot
|
||
|
|
> make g12b_w400_v1_defconfig
|
||
|
|
> make
|
||
|
|
> export UBOOTDIR=$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
