This page documents the current status of software support for the Quartz64 single-board computer, and provides links to resources to help prospective contributors get started. Information is kept current on a best-effort basis as various patches get accepted into the kernel.

Current Status

The following sections give an overview over the current status of different parts of the board. Some parts are waiting on a driver to be written or ported, others only need various adjustments.

General performance is poor, this is likely due to the AHB bus running slow, and may require some major rework of the clock layout to get to acceptable speeds.

Working

  • eMMC
  • SDMMC0 (SD cards)
  • GMAC (Gigabit Ethernet)
  • USB 2.0
  • SATA 2
  • SATA 3
  • UART
    • UART 0 (Pi-bus)
    • UART 1 (Bluetooth)
    • UART 2 (Pi-bus, debug)
  • Video Decode
    • VP8

Partially Working

  • PCI-Express Controller — everything but devices that need cache coherency (e.g. dGPUs) should work
  • USB 3.0 — at 2.0 speeds only, appears to be due to a PHY configuration issue
  • SDMMC1 (Wi-Fi) — AP6256 working, BL602 needs some work to make it flash firmware
  • I2C — works but is not yet exposed to the Pi-bus

Confirmed Broken

  • Nothing!

Needs Testing

  • GPU — Need a VOP-v2 DRM driver to get display output
  • Battery
  • Audio — Needs I2S driver
  • E-Paper
  • SPI — Needs a driver

Booting

Boot Order

The RK3566 boot ROM will search for a valid ID BLOCK in the following order on the support boot media:

  • SPI NOR flash
  • SPI NAND flash
  • eMMC
  • SD-Card

... if this fails, the boot ROM will initialize the USB0 port and wait for a connection from the Rockchip flash/boot tools.

Bootloader Flashing

As per pgwipeout's commit message:

  • Make a partition named uboot as partition number 1 at 8 MiB to 16 MiB
  • dd if=idblock.bin of=/dev/<mmc/sd> seek=64
  • dd if=uboot.img of=/dev/<mmc/sd>1
