USB SS1 on superspeed mode negotiation (custom carrier)

Hi,

I have custom carrier board which uses USB3 SS1 port from pins d42,d43,g42,g43 of TX1 for SS1, and b42,b43 for USB2 DP and DN in the same USB 3 type A connector. The problem is, when i plug a usb 3 camera to that connector, it negotiates as high speed (USB2) rather than super speed (USB3). Anybody succeeded to run USBSS1 in superspeed mode?

My devicetree is as follows: (same as 24.2 revision)

xusb_pad_ctl: xusb_padctl { /* Put common control config here */
	nvidia,ss_portmap = <0x21>;
	nvidia,lane_owner = <0xff56>; /* Use 0xF to disable lane assign */
	nvidia,lane-map = <0x14>;
	nvidia,enable-sata-port;
	status = "okay";
};

xusb@70090000 {
	/* nvidia,uses_external_pmic;
	/* nvidia,gpio_controls_muxed_ss_lanes; */
	nvidia,gpio_ss1_sata = <0>;
	nvidia,ulpicap = <0>; /* No ulpi support. can we remove */
	nvidia,portmap = <0x0e03>;
	nvidia,common_padctl = <&xusb_pad_ctl>;
	status = "okay";
};

As far as i understand, it enables the SS1 in nvidia,portmap = <0x0e03>; and allocates the lane in nvidia,lane_owner = <0xff56>. But it still can not negotiate as a superspeed port.

Any thoughts?

BR,

The dmesg xhci and usb related lines are: (the 5000M is the SS0, and the 480M is the SS1)

Hi bm2017,
The following is an example to enable usb 3.0 on USB_SS0 and PEX1

file: arch/arm64/boot/dts/tegra210-jetson-cv-base-p2597-2180-a00.dts

xusb_pad_ctl: xusb_padctl { /* Put common control config here */
nvidia,ss_portmap = <0x21>;
nvidia,lane_owner = <0xff56>; —> <0xf056>
nvidia,lane-map = <0x14>; --><0x04>
nvidia,enable-sata-port;
status = “okay”;
};

xusb@70090000 {
/* nvidia,uses_external_pmic;
/* nvidia,gpio_controls_muxed_ss_lanes; /
nvidia,gpio_ss1_sata = <0>;
nvidia,ulpicap = <0>; / No ulpi support. can we remove */
nvidia,portmap = <0x0e03>; --><0x0e07>
nvidia,common_padctl = <&xusb_pad_ctl>;
status = “okay”;
};
