doc: boards: amlogic: add documentation for ODROID-HC4
Browse files Browse the repository at this point in the history
Add separate documentation for the ODROID-HC4 board to ensure
users build U-Boot using the HC4 defconfig that enables PCIe
SATA boot. This avoids user frustration trying to boot after
using the C4 recipe which only works from SD card.

U-Boot for ODROID-HC4 (S905X3)
==============================

ODROID-HC4 is a variant of the ODROID-C4 single board computer manufactured by Hardkernel
with the following specification:

- Amlogic S905X3 Arm Cortex-A55 quad-core SoC
- 4GB DDR4 SDRAM
- 16MB XT25F128B SPI-NOR flash
- Gigabit Ethernet
- HDMI 2.1 display
- 7-pin GPIO header for OLED display and RTC
- 1x USB 2.0 host (micro)
- 2x SATA ports via ASM1061 PCIe to SATA controller
- microSD
- UART serial
- Infrared receiver

Schematics are available on the manufacturer website.

U-Boot Compilation
------------------

.. code-block:: bash
$ export CROSS_COMPILE=aarch64-none-elf-
$ make odroid-hc4_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 odroid-hc4 /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 so it is necessary to obtain binaries from sources 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
$ DIR=odroid-hc4
$ git clone --depth 1 https://github.com/hardkernel/u-boot.git -b odroidg12-v2015.01 $DIR
$ cd odroid-hc4
$ make odroidc4_defconfig
$ make
$ export UBOOTDIR=$PWD
Go back to mainline U-Boot source tree then:

.. code-block:: bash
$ mkdir fip
$ wget https://github.com/BayLibre/u-boot/releases/download/v2017.11-libretech-cc/blx_fix_g12a.sh -O fip/blx_fix.sh

Then write U-Boot to SD or SPI-NOR 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
