 |
|
I have a rock64 V2.0 board running with a headless config using gentoo sources for the kernel.
The serial port, gige and usb2 are working. usb3 is not working. XHCI and DWC are enabled
in the config:
| Code: | CONFIG_USB_DWC3=y
CONFIG_USB_DWC3_HOST=y
CONFIG_USB_DWC3_OF_SIMPLE=y
CONFIG_USB_DWC2=y
CONFIG_USB_DWC2_HOST=y
CONFIG_USB_XHCI_HCD=y
CONFIG_USB_XHCI_PLATFORM=y
|
The xhci usb code doesn't report anything in dmesg, but ohci and ehci do.
Any suggestions on config options to look at? |

Maybe you need this too: | Code: | | CONFIG_USB_XHCI_PCI=y |

Unfortunately adding PCI/PCIe configs doesn't help.
Looking at the 4.4.138 kernel referenced by pine64.org for the board, I see that its device tree has usb30xxx and uxb20xxx defintions for rock64 usb phys. It also has these source files in drivers/phy/rockchip:
| Code: | phy-rockchip-inno-usb2.c
phy-rockchip-inno-usb3.c |
The mainline kernels for 4.18.5 and 4.19-rc1 do not define the usb3 phy in the device tree and only have
| Code: | | phy-rockchip-inno-usb2.c |
in drivers/phy/rockchip. No additional files for rockchip in the staging drivers either.
It may be mainline just doesn't have usb3 support for rock64. |

Thanks for the links slycordinator.
I have applied the diffs from the commits to gentoo-sources-4.19.0. Needed
to patch rk3328-rock64.dts instead of rk3328-evb.dts.
The xhci hub now shows up and a disk device is created when a usb3 device
is plugged in.
It is unstable though. Early in the boot messages there is this message:
| Code: | | dwc3 ff600000.dwc3: Failed to get clk 'ref': -2 |
The system locked up when I plugged in an unpowered usb3 disk. Connecting
an external disk case with it's own power doesn't lock up. But dmesg sometimes has lots
of these messages:
| Code: | xhci-hcd xhci-hcd.0.auto: ERROR Transfer event for unknown stream ring slot 1 ep 6
xhci-hcd xhci-hcd.0.auto: @00000000fd7a29b0 00000000 00000000 1b000000 01078001 |
A 50G USB2 -> USB partition copy succeds with no messages.
Unplugging the usb3 port produces these:
| Code: | Cannot enable. Maybe the USB cable is bad?
usb usb5-port1: attempt power cycle |
and then the usb3 port is no longer usable. |

Perhaps it would be better to try using/installing the git kernel sources I linked to above. Not sure. I'm not a kernel dev lol.
Also, you may get further using the files/method located here: http://www.loper-os.org/?p=2295 It's a howto with image files for installing a very basic gentoo to the rk3328-roc-cc, which from what I can tell in specs is pretty much identical to the rock64.
