| U-Boot for Amlogic S400 (A113X)
 | |
| ===============================
 | |
| 
 | |
| S400 is a reference board manufactured by Amlogic with the following specifications:
 | |
| 
 | |
|  - Amlogic A113X ARM Cortex-A53 quad-core SoC @ 1.2GHz
 | |
|  - 1GB DDR4 SDRAM
 | |
|  - 10/100 Ethernet
 | |
|  - 2x USB 2.0 Host
 | |
|  - eMMC
 | |
|  - Infrared receiver
 | |
|  - SDIO WiFi Module
 | |
|  - MIPI DSI Connector
 | |
|  - Audio HAT Connector
 | |
|  - PCI-E M.2 Connectors
 | |
| 
 | |
| Schematics are available from Amlogic on demand.
 | |
| 
 | |
| U-Boot Compilation
 | |
| ------------------
 | |
| 
 | |
| .. code-block:: bash
 | |
| 
 | |
|     $ export CROSS_COMPILE=aarch64-none-elf-
 | |
|     $ make s400_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 s400 /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 but sources have been shared by Linux development contractor, Baylibre:
 | |
| 
 | |
| .. 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 n-amlogic-openlinux-20170606 amlogic-u-boot
 | |
|     $ cd amlogic-u-boot
 | |
|     $ make axg_s400_v1_defconfig
 | |
|     $ make
 | |
|     $ export FIPDIR=$PWD/fip
 | |
| 
 | |
| Go back to mainline U-Boot source tree then :
 | |
| 
 | |
| .. code-block:: bash
 | |
| 
 | |
|     $ mkdir fip

 | |
|               bl2
 | |
| 
 | |
|     $ $FIPDIR/axg/aml_encrypt_axg --bl3sig --input fip/bl30_new.bin \
 | |
|                                            --output fip/bl30_new.bin.enc \
 | |
|                                            --level v3 --type bl30

|                                            --output fip/bl31.img.enc \
 | |
|                                            --level v3 --type bl31
 | |
|     $ $FIPDIR/axg/aml_encrypt_axg --bl3sig --input fip/bl33.bin --compress lz4 \
 | |
|                                            --output fip/bl33.bin.enc \
 | |
|                                            --level v3 --type bl33
 | |
|     $ $FIPDIR/axg/aml_encrypt_axg --bl2sig --input fip/bl2_new.bin \
 | |
|                                            --output fip/bl2.n.bin.sig
 | |
|     $ $FIPDIR/axg/aml_encrypt_axg --bootmk \
 | |
|                                   --output fip/u-boot.bin \
 | |
|                                   --bl2 fip/bl2.n.bin.sig \

 | |
|                                   --bl33 fip/bl33.bin.enc --level v3
 | |
| 
 | |
| 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
