| U-Boot for Amlogic U200
 | |
| =======================
 | |
| 
 | |
| U200 is a reference board manufactured by Amlogic with the following
 | |
| specifications:
 | |
| 
 | |
|  - Amlogic S905D2 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
 | |
|  - 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 u200_defconfig
 | |
|     $ make
 | |
| 
 | |
| Image creation
 | |
| --------------
 | |
| 
 | |
| For simplified usage, pleaser refer to :doc:`pre-generated-fip` with codename `u200`
 | |
| 
 | |
| 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:
 | |
| 
 | |
| .. 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 g12a_u200_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 mainline U-Boot source tree then :
 | |
| 
 | |
| .. code-block:: bash
 | |
| 
 | |
|     $ mkdir fip
 | |
| 
 | |
