The Quartz64 Model B

The Quartz64 is the most recent Single Board Computer offering from PINE64, with Model A initially released in June of 2021 and Model B in May of 2022. It is powered by a Rockchip RK3566 Quad-Core ARM Cortex A55 64-Bit Processor with a MALI G-52 GPU.

Key features include a PCIe x4 open ended slot (model A) or m.2 (model B) using one Gen2 lane electrically, and the use of LPDDR4 RAM.

The Quartz64 has three LPDDR4 system memory options: 2GB, 4GB or 8GB. For booting, there is an eMMC module socket (supporting up to 128GB) and microSD slot, as well as a footprint to solder on an SPI flash chip. The board is equipped with HDMI, 1x USB 3.0 type A Host, 3x USB 2.0 Host, Gigabit Ethernet, SATA (model A), GPIO Bus, MiPi DSI interface, e-ink interface (model A), eDP interface (model A), touch Panel interface (model A), MiPi CSI interface, as well as many other device interfaces such as UART, SPI, I2C, for makers to integrate with sensors and other peripherals. Many different Operating Systems (OS) are freely available from the open source community, such as Linux (Ubuntu, Debian, Arch), BSD, and Android.

The PCIe implementation on the RK3566 is much more compatible with a wide range of devices compared to the one on the RK3399 used on the ROCKPro64. This means a lot more devices should work (excluding dGPUs due to a lack of cache snooping ability).

Combo PHYs

Rk3566 phy.png

Several of the I/O options on the RK3566 used in the Quartz64 are using the same I/O lines, meaning that they cannot be used at the same time. The above diagram illustrates how they are connected.

In particular, USB 3.0 and the SATA connector on the board are mutually exclusive, and the PCI-e 2.0 lane can be reconfigured into a second SATA port, though an adapter cable needs to be fashioned for this to be useful.

Datasheets for Components and Peripherals

Development efforts

Main Article: Quartz64 Development

Information and resources of the ongoing development effort for the Quartz64 can be found on the Quartz64 Development page, where the current status of various board functions can be found, and whether they have landed in upstream.

Enclosures

(Please expand this section with more cases known to work.)

Model "A"

All enclosures that fit the ROCKPro64 should fit the Quartz64 Model "A", as the I/O has been laid out the same on purpose.

Model "B"

Troubleshooting

Stability/Boot Issues With Missing Battery Shunt

If there is no battery plugged into the board, the jumper labelled "ON/OFF_BATT" must be in place. If this is set wrong, stability issues such as failures to boot will occur.

No Ethernet Connectivity

Make sure the kernel is built with CONFIG_MOTORCOMM_PHY set to y. Building it as a module (m) and then relying on module auto-loading is unlikely to work, because if the generic PHY driver is built in it will bind to the PHY first, unless you include the motorcomm module in your initramfs.

Note: Starting with Debian's 6.1~rc3-1~exp1 kernel the module is included, but set to m and I (Diederik) have verified that it gets included in the initramfs and works on Model-A and Model-B with the Quartz64#Plebian images.

"Model A" Acrylic Case Doesn't Fit

The Quartz64 does not really fit onto the bottom plate of the "Model A" Acrylic Open Enclosure. This is because the "Mic" connector at the bottom of the board interferes with one of the posts. A workaround is to find out which post that is (you have a 50% chance of guessing it right, accounting for rotating the board) and then filing away the corner of the post pointing inwards by a few millimetres.

Quartz64-audio-jack-spacer-issue.jpg

An alternate solution may be to place plastic spacers with a smaller outer diameter in between the acrylic bottom plate posts and the SBC board.

No GPU Acceleration with Debian "Bullseye" Userland

Debian Bullseye ships a Mesa version that is too old to contain the required patches for the RK356x SoC's GPU. You can (at your own risk) use the current Debian Testing version , called "Bookworm".

Wireless Connectivity Doesn't Work

ROCKPro64 wireless module may have CYW43455 or CYW43456 chips on board (not sure if this is the same for Quartz64 model B). Both chips are supported by brcmfmac wi-fi driver and btbcm bluetooth driver.

For CYW43455 drivers attempt to load /lib/firmware/brcm/brcmfmac43455-sdio.bin for wi-fi and /lib/firmware/brcm/BCM4345C0.hcd for bluetooth. Corresponding firmware files for CYW43456 are /lib/firmware/brcm/brcmfmac43456-sdio.bin and /lib/firmware/brcm/BCM4345C5.hcd.

On Manjaro firmware files for both bluetooth and wi-fi on CYW43456 on are provided by ap6256-firmware package (pacman -S ap6256-firmware).

However for CYW43455 wi-fi firmware is in the linux-firmware package and bluetooth is in the firmware-raspberrypi (pacman -S linux-firmware firmware-raspberrypi). linux-firmware package is missing device specific symlinks for quartz64-a. To create them execute: 

# ln -s brcmfmac43455-sdio.bin /lib/firmware/brcm/brcmfmac43455-sdio.pine64,quartz64-a.bin
# ln -s brcmfmac43455-sdio.AW-CM256SM.txt /lib/firmware/brcm/brcmfmac43455-sdio.pine64,quartz64-a.txt

As of 2022-10-19 device tree in mainline kernel for Quartz64 model A has wrong configuration for the bluetooth driver. Patch is submitted to the LKML. It's possible to modify dtb file provided by the current kernel using device tree compiler to enable bluetooth or perform make dtbs in the patched kernel tree to get updated dtb file (arch/arm64/boot/dts/rockchip/rk3566-quartz64-a.dtb). Issue manifests itself with following errors in `dmesg`: 

 command 0x0c03 tx timeout
 Bluetooth: hci0: BCM: Reset failed (-110)

How-To

Connect Debug UART

The easiest way to get debug output is to connect a 3.3V 1.5mbaud capable UART adapter to the board.

To connect it, connect the ground lead to pin 6, and the RX/TX leads to pins 8 and 10 (consider swapping them if you get no output, things are often mislabelled). These pins are "UART2" in the above GPIO table.

Open a serial terminal at 1500000 bauds, e.g. 

$ picocom -b 1500000 /dev/ttyUSB0

Disable Heartbeat LED (Linux)

The flashing LED is called the "heartbeat LED", it blinks in a heart rhythm like fashion once the kernel is running. To disable it, you can run 

# echo none > /sys/class/leds/user-led/trigger

On model A LED device is called "diy-led", not "user-led".

On a system with systemd, you can do this as soon as the system is ready to be logged in with a systemd unit like this: 

[Unit]
Description=Turn off heartbeat LED
Wants=multi-user.target
After=multi-user.target

[Install]
WantedBy=multi-user.target

[Service]
Type=simple
ExecStart=sh -c 'echo none > /sys/class/leds/user-led/trigger'

Place it in /etc/systemd/system/user-led.service, and run 

# systemctl daemon-reload
# systemctl enable user-led.service

Upon rebooting, you will now notice that the heartbeat LED will blink during boot-up, but stops blinking as soon as the multi-user target is reached (i.e. the user can log in).

SATA on model A

On model A USB 3.0 and SATA ports are using the same I/O line and can't be used simultaneously. By default USB 3.0 is enabled in linux device tree and SATA is disabled. FDT modifications are required to turn SATA on.

Following script is tested on Manjaro but should work on the other distributions with minimal changes. Device tree compiler package usually provides fdtput command (on Manjaro run: pacman -S dtc) 

# cp /boot/dtbs/rockchip/rk3566-quartz64-a.dtb /boot/dtbs/rockchip/rk3566-quartz64-a-sata.dtb
# fdtput -t s -v /boot/dtbs/rockchip/rk3566-quartz64-a-sata.dtb /usb@fd000000 status disabled
# fdtput -t s -v /boot/dtbs/rockchip/rk3566-quartz64-a-sata.dtb /sata@fc400000 status okay
# sed -i 's#^FDT /dtbs/rockchip/rk3566-quartz64-a.dtb$#FDT /dtbs/rockchip/rk3566-quartz64-a-sata.dtb#' /boot/extlinux/extlinux.conf
# systemctl reboot

Frequently Asked Questions

Do I Need A Fan/What Heatsink Do I Need?

You don't need a fan. The 20mm medium heatsink for Model A is plenty enough. For Model B, the fan type heatsink will do fine.

Can This Run A Minecraft Server?

Yes! Sort of. Testing on an 8GB Model A with PaperMC, User:CounterPillow was able to out-row world generation in a boat with just one player online, but aside from the slow world gen (which can be pre-generated) the server handled things like TNT explosions and mobs fine. It'll probably do okay with 1-3 players.

Do I Need The 5A Power Supply For Model A?

You only need the 5A power supply for Model A if you plan on connecting hard disk drives to the 12V header on the board.

How Much Power Does It Consume?

For Model B, it's <2W in idle (powertop tunables not set), and <5W under full CPU load (stress-ng -c4). Model A will be similar as it's the same SoC.
