+ - 4 x USB 2.0 Host
+ - eMMC, SPI NOR Flash
+ - Infrared receiver
+
+Schematics are available on the manufacturer website.
+
+U-Boot compilation
+------------------
+
+.. code-block:: bash
+
+    $ export CROSS_COMPILE=aarch64-none-elf-
+    $ make libretech-ac_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:
+
+.. 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 libretech-ac amlogic-u-boot
+    $ cd amlogic-u-boot
+    $ wget https://raw.githubusercontent.com/BayLibre/u-boot/libretech-cc/fip/blx_fix.sh
+    $ make libretech_ac_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_20180418.tar.gz
+    $ tar xfz buildroot_openlinux_kernel_4.9_fbdev_20180418.tar.gz buildroot_openlinux_kernel_4.9_fbdev_20180418/bootloader
+    $ export BRDIR=$PWD/buildroot_openlinux_kernel_4.9_fbdev_20180418
+
+Go back to mainline U-Boot source tree then :
+
+.. code-block:: bash
+
+    $ mkdir fip
+
+    $ cp $UBOOTDIR/build/scp_task/bl301.bin fip/
+    $ cp $UBOOTDIR/build/board/amlogic/libretech_ac/firmware/bl21.bin fip/
+    $ cp $UBOOTDIR/build/board/amlogic/libretech_ac/firmware/acs.bin fip/
+    $ cp $BRDIR/bootloader/uboot-repo/bl2/bin/gxl/bl2.bin fip/
+    $ cp $BRDIR/bootloader/uboot-repo/bl30/bin/gxl/bl30.bin fip/
+    $ cp $BRDIR/bootloader/uboot-repo/bl31/bin/gxl/bl31.img fip/
+    $ cp u-boot.bin fip/bl33.bin
+
+    $ sh $UBOOTDIR/blx_fix.sh \
+    	fip/bl30.bin \
+    	fip/zero_tmp \
+    	fip/bl30_zero.bin \
+    	fip/bl301.bin \
+    	fip/bl301_zero.bin \
+    	fip/bl30_new.bin \
+    	bl30
+
+    $ $BRDIR/bootloader/uboot-repo/fip/acs_tool.pyc fip/bl2.bin fip/bl2_acs.bin fip/acs.bin 0
+
+    $ sh $UBOOTDIR/blx_fix.sh \
+    	fip/bl2_acs.bin \
+    	fip/zero_tmp \
+    	fip/bl2_zero.bin \
+    	fip/bl21.bin \
+    	fip/bl21_zero.bin \
+    	fip/bl2_new.bin \
+    	bl2
+
+    $ $BRDIR/bootloader/uboot-repo/fip/gxl/aml_encrypt_gxl --bl3enc --input fip/bl30_new.bin
+    $ $BRDIR/bootloader/uboot-repo/fip/gxl/aml_encrypt_gxl --bl3enc --input fip/bl31.img
+    $ $BRDIR/bootloader/uboot-repo/fip/gxl/aml_encrypt_gxl --bl3enc --input fip/bl33.bin
+    $ $BRDIR/bootloader/uboot-repo/fip/gxl/aml_encrypt_gxl --bl2sig --input fip/bl2_new.bin --output fip/bl2.n.bin.sig
+    $ $BRDIR/bootloader/uboot-repo/fip/gxl/aml_encrypt_gxl --bootmk \
+    		--output fip/u-boot.bin \
+    		--bl2 fip/bl2.n.bin.sig \
+    		--bl30 fip/bl30_new.bin.enc \
+    		--bl31 fip/bl31.img.enc \
+    		--bl33 fip/bl33.bin.enc
+
+and then write the image to SD with:
+
+.. code-block:: bash
+
+    $ DEV=/dev/your_sd_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=444
