u-boot Waiting on ATF sources
Device Tree Basic Quartz64 Model A device tree in review[2]
Gigabit Ethernet Linux Mainline rk3566-gmac As of 5.14[3]

Microphone In review[11] rockchip-saradc Headphone jack mic seems to connect to SARADC_VIN2_HP_HOOK, so I'm pretty sure that the dtsi and driver changes are needed for that mic to work

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
  • GIC — needs errata published by Rockchip to get upstream to add device-specific workarounds[12]

Confirmed Broken

  • Nothing!

Needs Testing

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

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
