11:38 <Guest16> Hey!

11:38 <Guest16> Does anyone know what all kernel config options have to be set for USB Host mode on RK3566?

11:38 <Guest16> Right now, device mode works for me and host mode should technically work? I see two xHCI host controllers in lsusb but I cant get it to recognize any slave device.

11:38 <Guest16> This is the defconfig I am using:

12:16 <CounterPillow> Guest16: this might give some pointers, but I don't know how accurate/up to date it is these days https://wiki.pine64.org/wiki/Quartz64_Development#Linux_Kernel_Config_Options

12:16 <CounterPillow> (Pretty sure the motorcomm note is wrong for example)

12:21 <CounterPillow> but also if this is a USB Type-C port then there are some problems, try orienting the cable the other way.

12:22 <CounterPillow> We currently don't handle the orientation switch properly, as it's not entirely figured out yet whether the PHY or the controller should do it

12:27 <CounterPillow> I sent this as a proposed solution, but Neil Armstrong and I agreed that it's a hack, so he said he'll look into solving it in dwc3 instead https://lore.kernel.org/all/20250610-rk3576-sige5-usb-v4-3-7e7f779619c1@collabora.com/

13:15 <Guest16> CounterPillow: I tried both ways yet it  doesnt seem to work

13:15 <Guest16> I've also tried multiple cables. I have the combophy and usb2phys enabled.

13:15 <Guest16> Im more surprised that device mode works on the otg port but host mode works on neither...

13:34 <CounterPillow> does the Device Tree specifically set a mode?

13:34 <CounterPillow> dr_mode = etc

13:37 <Guest16> https://github.com/torvalds/linux/blob/37816488247ddddbc3de113c78c83572274b1e2e/arch/arm64/boot/dts/rockchip/rk356x-base.dtsi#L266

13:37 <Guest16> yeah.

13:45 <CounterPillow> and it doesn't change this to some other value in your device specific DT?

13:50 <Guest16> it shouldnt. its the radxa zero 3w. sorry for not mentioning this earlier

13:55 <CounterPillow> The radxa zero 3* dts doesn't seem to enable usb_host0_ohci/ehci or usb_host1_ohci/ehci which seems suspicious.

14:21 <Guest16> oh. every device i tried is usb2.0. so would i need to enable at least eHCI?

14:33 <Guest67> CounterPillow:  oops,  i seem to have lost my  Guest16 nick

14:34 <CounterPillow> I think you'll need to enable both even if it's an xhci device for USB enumeration reasons, though I may be wrong here

14:34 <Guest67> just change the status to enabled right?

14:34 <Guest67> *okay

14:45 <CounterPillow> yes, to okay

15:02 <Guest67> no change. hmm

16:05 <Guest16> CounterPillow I wonder if linux is doing something funky. usually, I cant power up the board from the xhci host port. but if linux boots and i remove the cable from the 2.0 otg port while leaving my phone connected to the xhci host port, it remains on!

16:05 <Guest16> Could there be some issue  with dwc3 because I am using the otg  port? can i use the 3.0 host while using the 2.0otg in device mode?

16:12 <CounterPillow> May be a missing regulator dependency in the DT

16:16 <Guest16> uh i should have RK817 and the FAN53555 drivers running

16:31 <CounterPillow> Check the schematic for what power rail goes to the USB port's VBUS, then follow it to see if it's gated by some GPIO-enabled regulator that's either missing from the DT entirely or just missing a reference to it in the corresponding usb phy node

16:36 <Guest16> CounterPillow: it seems to be gated by a SY6280AAC but the enable pin seems to be locked high with a 10k pullup

16:44 <Guest16> Although, GPIO0_C5_d seems to drive a USB3.0_EN_H which controlls the CH482D analog differential switch.

17:50 <Guest16> hm i drove it high with `gpioset -c 0 21=1` and usb still doesnt work. maybe i am doing something wrong with gpioset or maybe im going the wrong way?

18:26 <Guest16> ah well i must have something wrong in my kernel config since this all works fine with default aarch64 config

18:47 <Guest16> USB is up! i just had disabled some typec port controllers!

18:59 <Guest16> hmm okay well  while usb works rn it doesnt work if the usb2.0 port is plugged in. if i power the board through the +5V pin i can use the 3.0 port but if i use the otg to power it, i cant use the 3.0. i do have scripts running which immediately setup an accessory on init though

19:15 <Guest16> no  wait - i mixed things up

19:15 <Guest16> USB DOES work for all non-drd devices(i use a twelvesouth  staygo)

19:15 <Guest16> USB DOES NOT work for drd devices(i  am using my phone). while it says that usb is connected and is controlled by the other device, it  says my phone is charging it and i cant see it in lsusb

19:15 <Guest16> these are with the usb 2.0 otg plugged in

19:15 <Guest16> if i disconnect the otg andf try to power with pins, even the hub doesnt work(the eth lights keep flickering)

19:44 <CounterPillow> Yeah, expect there to be a lot of issues with Type-C stuff at the moment.
