Micro-USB OTG function doesn't work for Xavier Carrier board without TYPE-C

Dear,

We designed our own Xavier carrier board, with no type-c and PD controller, but we have two TYPE-A USB and one Micro-USB as OTG, my problem is the Micro-USB OTG cann’t be used as Device, but as Host is fine.

  1. I disabled “typec-extcon” in dts, and add “vbus_id_extcon” with ID Pin and VBUS_DETECT
  2. HW has only ID Pin, but no VBUS_DETECT Pin (I use a fake pin for that in dtsi )
  3. Two TYPE-A USB and Micro-USB as host to connnect USB Devices(such as U-Disk, USB Mouse) works fine, but Micro-USB as Device failed, when it connect to PC there is no response.
  4. USB VBUS Supply the same as E-SATA, so I modified it as below:
    tegra194-power-tree-p2888-0001-p2822-1000.dtsi
xusb_padctl@3520000 {
		pex_dvdd-supply = <&p2888_spmic_sd0>;
		pex_hvdd-supply = <&p2888_spmic_sd1>;
		pex_pll_hvdd-supply = <&p2888_spmic_sd1>;
		vclamp_usb-supply = <&p2888_spmic_sd3>;
		avdd_usb-supply = <&p2888_spmic_ldo5>;
		avdd_pll_nvhs_eutmip-supply = <&p2888_spmic_sd1>;
		ports {
			usb2-0 {
				vbus-supply = <&p2822_vdd_5v_sata>;
			};
			usb2-1 {
				vbus-supply = <&p2822_vdd_5v_sata>;
			};
			usb2-2 {
				vbus-supply = <&p2822_vdd_5v_sata>;
			};
			usb2-3 {
				vbus-supply = <&p2822_vdd_5v_sata>;
			};
		};
	};
  1. USB HW Design is attached.

Dear Sir,

I have fixed the problem, pls ignore this topic.

Hi dennis_Leetop

We have the same Problem at the moment. Can you explain us what was the solution?
Thank you!

Kind regards

Hi sevm89,

Fisrt, disable TYPE-C function like: ucsi_ccg
Second, add a new extcon for USB configuration
Third, replace extcon-cables in tegra_xudc and tegra_xhci

Modify two dtsi files:
tegra194-soc-base.dtsi
tegra194-p2888-0001-p2822-0000-common.dtsi

Hi dennis_Leetop

Thank you for your fast answer, we were able to make it work.

Best regards
