  • Architecture | dpkg --print-architecture
  • arm64
  • SBC model | echo $G_HW_MODEL_NAME or (EG: RPi3)
  • Radxa ZERO 3 (aarch64)
  • Power supply used | (EG: 5V 1A RAVpower)
  • 5v 3A
  • SD card used | (EG: SanDisk ultra)
  • SanDisk Ultra

Additional Information (if applicable)

  • Can this issue be replicated on a fresh installation of DietPi?
    • Yes

Steps to reproduce

  1. Run ls -al /boot/dtb/rockchip/overlay
  2. No dwc3 overlays appear

Expected behaviour

  • An overlay to enable host mode on the rk3568 OTG port should be there.

Actual behaviour

  • Overlay is missing

Extra details

  • I previously opened a post on something similar to this ( Radxa Zero 3w OTG Port Not Loading Peripherals ) when I first started using dietpi and got some help getting the overlay started up in the first place. I did find some usb-c overlays in the list this time, but to no avail. Should we expect a dwc3 overlay? Has that item in the tree been renamed? Should I open a github issue on this? Am I just doing something wrong again lol

    Thanks!

It’s either not shipped with this kernel or in another place. But you could just use this file:
https://github.com/armbian/linux-rockchip/blob/bd032d59a096344a1f29acf9965d8c46f9a847a8/arch/arm64/boot/dts/rockchip/overlay/rk3568-dwc3-host.dts
You would need to compile it to a dtb file and your current device tree must have a node with the same label (usbdrd_dwc3) to make it work.

You can check with

sudo dtc -I dtb -O dts /sys/firmware/fdt 2>/dev/null | grep -nE 'usbdrd|dwc3|dr_mode'
