U-Boot for Khadas VIM3 (A311D)
|
|
==============================
|
|
|
|
Khadas VIM3 is a Single Board Computer manufactured by Shenzhen Wesion Technology Co. Ltd
|
|
with the following specifications:
|
|
|
|
- Amlogic A311D Arm Cortex-A53 dual-core + Cortex-A73 quad-core SoC
|
|
- 4GB LPDDR4 SDRAM
|
|
- Gigabit Ethernet
|
|
- HDMI 2.1 display
|
|
- 40-pin GPIO header
|
|
- 1 x USB 3.0 Host, 1 x USB 2.0 Host
|
|
- eMMC, microSD
|
|
- M.2
|
|
- Infrared receiver
|
|
|
|
Schematics are available on the manufacturer website.
|
|
|
|
PCIe Setup
|
|
----------
|
|
|
|
The on-board MCU can mux the PCIe/USB3.0 shared differential lines using a FUSB340TMX USB
|
|
3.1 SuperSpeed Data Switch between a USB3.0 Type-A connector and an M.2 Key M slot. The
|
|
PHY driving these differential lines is shared between the USB3.0 controller and the PCIe
|
|
Controller, thus only a single controller can use it.
|
|
|
|
To setup for PCIe run the following commands from U-Boot then power-cycle the board:
|
|
|
|
.. code-block:: none
|
|
|
|
i2c dev i2c@5000
|
|
i2c mw 0x18 0x33 1
|
|
|
|
To revert to USB3.0 run the following commands from U-Boot then power-cycle the board:
|
|
|
|
.. code-block:: none
|
|
|
|
i2c dev i2c@5000
|
|
i2c mw 0x18 0x33 0
|
|
|
|
U-Boot Compilation
|
|
------------------
|
|
|
|
.. code-block:: bash
|
|
|
|
$ export CROSS_COMPILE=aarch64-none-elf-
|
|
$ make khadas-vim3_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 khadas-vim3 /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=vim3-u-boot
|
|
$ git clone --depth 1 https://github.com/khadas/u-boot.git -b khadas-vims-v2015.01 $DIR
|
|
|
|
$ cd vim3-u-boot
|
|
$ make kvim3_defconfig
|
|
$ make CROSS_COMPILE=aarch64-none-elf-
|
|
$ export UBOOTDIR=$PWD
|
|
|
|
Go back to the mainline U-Boot source tree then:
|
|
|
|
.. code-block:: bash
|
|
|
|
$ mkdir fip
|
|
|
|

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
