https://elinux.org/Jetson/TX2_USBHello,
I’m unable to get USB3.0 port 0 and USB2.0 port 0 working on my custom Jetson
TX2 carrier card using Jetpack 4.2.1. My carrier card works fine using Jetpack
3.2.1.
I’ve read:
- https://devtalk.nvidia.com/default/topic/1013740/jetson-tx2/tx2-config-3-for-usb-lane-mapping/1
- https://devtalk.nvidia.com/default/topic/1001771/jetson-tx2/no-usb-support-on-custom-base-carrier-board/
- Jetson/TX2 USB - eLinux.org
I’m using a display port and thus I’m flashing tegra186-quill-p3310-1000-c03-00-dsi-dp.dtb. The display port is working fine.
I have two USB ports on my carrier card. The USB3.0 port is connected to pins
A38, A39, C43, C44, F43 and F44. The USB2.0 port is connected to pins B39 and B40.
To turn the USB power on I modified the power-tree with
tegra186-quill-power-tree-p3310-1000-a00-00.dtsi
pinctrl@3520000 {
vbus-0-supply = <&vdd_usb0_5v>;
vbus-1-supply = <&vdd_usb1_5v>;
vbus-2-supply = <&vdd_usb2_5v>;
vbus-3-supply = <&vdd_usb0_5v>; // <-- changed this
vddio-hsic-supply = <&battery_reg>;
avdd_usb-supply = <&spmic_sd3>;
vclamp_usb-supply = <&spmic_sd2>;
avdd_pll_erefeut-supply = <&spmic_sd2>;
};
and turned the regulators always on with.
tegra186-cvb-prod-p2597-b00-p3310-1000-a00-00.dtsi
vdd_usb1_5v: regulator@5 {
compatible = "regulator-fixed-sync";
reg = <5>;
regulator-name = "vdd-usb1-5v";
regulator-min-microvolt = <5000000>;
regulator-max-microvolt = <5000000>;
gpio = <&tegra_main_gpio TEGRA_MAIN_GPIO(L, 5) 0>;
gpio-open-drain;
enable-active-high;
regulator-always-on; /* JML 20190801 */
regulator-boot-on; /* JML 20190801 */
};
en_vdd_ts_1v8: regulator@6 {
compatible = "regulator-fixed-sync";
reg = <6>;
regulator-name = "en-vdd-ts-1v8";
regulator-min-microvolt = <1800000>;
regulator-max-microvolt = <1800000>;
gpio = <&gpio_i2c_0_74 1 1>;
enable-active-high;
regulator-always-on;
regulator-boot-on;
};
That works fine.
Then I configured the USB ports by removing unused ports and re-configuring OTG
as a HOST port

When I boot, on the display I get the final configuration GUI. I can’t finish
the configuration because neither USB port works. On the debug serial console I
get:

What do I need to do to get the USB ports working properly? I need help getting xusb_padctl@3520000 and pinctrl@3520000 configured properly.
Thanks
