18U-Boot compilation
19------------------
20
21.. code-block:: bash
22
23    $ export CROSS_COMPILE=aarch64-none-elf-
24    $ make sei510_defconfig
25    $ make
26
27Image creation
28--------------
29
30Amlogic doesn't provide sources for the firmware and for tools needed
31to create the bootloader image, so it is necessary to obtain them from
32the git tree published by the board vendor:
33
34.. code-block:: bash
35
36    $ wget https://releases.linaro.org/archive/13.11/components/toolchain/binaries/gcc-linaro-aarch64-none-elf-4.8-2013.11_linux.tar.xz
37    $ wget https://releases.linaro.org/archive/13.11/components/toolchain/binaries/gcc-linaro-arm-none-eabi-4.8-2013.11_linux.tar.xz
38    $ tar xvfJ gcc-linaro-aarch64-none-elf-4.8-2013.11_linux.tar.xz
39    $ tar xvfJ gcc-linaro-arm-none-eabi-4.8-2013.11_linux.tar.xz
40    $ 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
41    $ git clone https://github.com/BayLibre/u-boot.git -b buildroot-openlinux-20180418 amlogic-u-boot
42    $ cd amlogic-u-boot
43    $ make g12a_u200_v1_defconfig
44    $ make
45    $ export UBOOTDIR=$PWD
46
47Download the latest Amlogic Buildroot package, and extract it :
48
49.. code-block:: bash
50
51    $ wget http://openlinux2.amlogic.com:8000/ARM/filesystem/Linux_BSP/buildroot_openlinux_kernel_4.9_fbdev_20180706.tar.gz
52    $ tar xfz buildroot_openlinux_kernel_4.9_fbdev_20180706.tar.gz buildroot_openlinux_kernel_4.9_fbdev_20180706/bootloader
53    $ export BRDIR=$PWD/buildroot_openlinux_kernel_4.9_fbdev_20180706
54    $ export FIPDIR=$BRDIR/bootloader/uboot-repo/fip
55
56Go back to mainline U-Boot source tree then :
57
58.. code-block:: bash
59
60    $ mkdir fip

125
126.. code-block:: bash
127
