This device is based on the Amlogic S905D3. See the SoC page for common tips, guides and troubleshooting steps

The AML-S905D3-CC is a single board computer made by Libre Computer. Quite well supported in mainline because of the manufacturer funding mainline development for this board.

Installation

Installation to an external USB storage device and eMMC have been tested and confirmed working.

Use pmbootstrap to build your own image, like so:

$ pmbootstrap init # manufacturer: librecomputer, codename: solitude

If installing to eMMC

If you're installing to USB or an SD card, you can skip this entirely until pmbootstrap install

Make sure the SPI/MMC switch is set to SPI and connect the board to your computer using a USB-C cable. Interrupt U-Boot and type the following in the prompt:

=> ums 0 mmc 0

Your eMMC device should appear as a normal storage device on your computer, after which you can:

$ pmbootstrap install --sdcard=/dev/storage_device # replace `mmcblk0` with the path of your USB storage device or eMMC/SD

Issues

HDMI audio

HDMI audio seems to not work with my monitor at least. Could be because there's no UCM profile or asound.state provided at the moment.

Ethernet

Ethernet works.

On older kernels and SPI flash firmware, it may not work however. The following is printed to dmesg:

[   87.674546] stmmaceth ff3f0000.ethernet eth0: Register MEM_TYPE_PAGE_POOL RxQ-0
[   87.899591] stmmaceth ff3f0000.ethernet eth0: PHY [mdio_mux-0.0:00] driver [RTL8211F Gigabit Ethernet] (irq=26)
[   88.107415] stmmaceth ff3f0000.ethernet: Failed to reset the dma
[   88.107432] stmmaceth ff3f0000.ethernet eth0: stmmac_hw_setup: DMA engine initialization failed
[   88.107440] stmmaceth ff3f0000.ethernet eth0: __stmmac_open: Hw setup failed

If that happens to you, upgrade your SPI flash U-Boot. Instructions for how to do that can be found here: https://hub.libre.computer/t/libre-computer-board-bios-firmware-update-images/3113
