20U-Boot compilation
21------------------
22
23.. code-block:: bash
24
25    $ export CROSS_COMPILE=aarch64-none-elf-
26    $ make sei610_defconfig
27    $ make
28
29Image creation
30--------------
31
32Amlogic doesn't provide sources for the firmware and for tools needed
33to create the bootloader image, so it is necessary to obtain them from
34the git tree published by the board vendor:
35
36.. code-block:: bash
37
38    $ wget https://releases.linaro.org/archive/13.11/components/toolchain/binaries/gcc-linaro-aarch64-none-elf-4.8-2013.11_linux.tar.xz
39    $ wget https://releases.linaro.org/archive/13.11/components/toolchain/binaries/gcc-linaro-arm-none-eabi-4.8-2013.11_linux.tar.xz
40    $ tar xvfJ gcc-linaro-aarch64-none-elf-4.8-2013.11_linux.tar.xz
41    $ tar xvfJ gcc-linaro-arm-none-eabi-4.8-2013.11_linux.tar.xz
42    $ 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
43    $ git clone https://github.com/BayLibre/u-boot.git -b buildroot-openlinux-4.9-g12a-201904 amlogic-u-boot
44    $ cd amlogic-u-boot
45    $ make sm1_ac200_v1_defconfig
46    $ make
47    $ export UBOOTDIR=$PWD
48
49Download the latest Amlogic Buildroot package, and extract it :
50
51.. code-block:: bash
52
53    $ wget http://openlinux2.amlogic.com:8000/ARM/filesystem/buildroot-openlinux-A113-201901.tgz
54    $ tar xfz buildroot-openlinux-A113-201901.tgz buildroot-openlinux-A113-201901/bootloader
55    $ export BRDIR=$PWD/buildroot-openlinux-A113-201901
56    $ export FIPDIR=$BRDIR/bootloader/uboot-repo/fip
57
58Go back to mainline U-Boot source tree then :
59
60
61.. code-block:: bash
62
63    $ mkdir fip
64

128
129.. code-block:: bash
130

132    $ dd if=fip/u-boot.bin.sd.bin of=$DEV conv=fsync,notrunc bs=512 skip=1 seek=1
