| U-Boot for Khadas VIM3L (S905D3) |
| ================================ |
| |
| Khadas VIM3L is a Single Board Computer manufactured by Shenzhen Wesion Technology Co. Ltd |
| with the following specifications: |
| |
| - Amlogic S905D3 Arm Cortex-A55 quad-core SoC |
| - 2GB 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-vim3l_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-vim3l /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=vim3l-u-boot |
| $ git clone --depth 1 https://github.com/khadas/u-boot.git -b khadas-vims-v2015.01 $DIR |
| |
| $ cd vim3l-u-boot |
| $ make kvim3l_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 |
| |
| $ 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 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 |
