U-Boot for Amlogic W400 (S922X)
|
|
===============================
|
|
|
|
W400 is a reference board manufactured by Amlogic with the following specification:
|
|
|
|
- Amlogic S922X ARM Cortex-A53 dual-core + Cortex-A73 quad-core SoC
|
|
- 2GB DDR4 SDRAM
|
|
- 10/100 Ethernet (Internal PHY)
|
|
- 1x 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.

U-Boot Compilation
|
|
------------------
|
|
|
|
.. code-block:: bash
|
|
|
|
$ export CROSS_COMPILE=aarch64-none-elf-
|
|
$ make w400_defconfig
|
|
$ make
|
|
|
|
U-Boot Signing with Pre-Built FIP repo
|
|
--------------------------------------
|
|
|
|
.. code-block:: bash
|
|
|
|
$ git clone https://github.com/LibreELEC/amlogic-boot-fip --depth=1
|
|
$ cd amlogic-boot-fip
|
|
$ mkdir my-output-dir
|
|
$ ./build-fip.sh jethub-j100 /path/to/u-boot/u-boot.bin my-output-dir
|
|
|
|
U-Boot Manual Signing
|
|
---------------------
|
|
|
|
Amlogic does not provide sources for the firmware and tools needed to create a bootloader
|
|
image so it is necessary to obtain binaries from sources published by the board vendor:
|
|
|
|
.. code-block:: bash
|
|
|
|
$ 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:
|
|
|
|
.. code-block:: bash
|
|
|
|
$ 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 the mainline U-Boot source tree then:
|
|
|
|
.. code-block:: bash
|
|
|
|
$ mkdir fip
|
|
|
|
$ wget https://github.com/BayLibre/u-boot/releases/download/v2017.11-libretech-cc/blx_fix_g12a.sh -O fip/blx_fix.sh

Then write U-Boot to SD or eMMC with:
|
|
|
|
.. code-block:: bash
|
|
|
|
$ DEV=/dev/boot_device
|
|
$ 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=440
