We are design custom carrier board with USB2.0-Port0 interface connected to usb type AB connector. We are able to download the SDK with this USB interface, but the same is USB is not working after kernel boot. No device/host is getting detected on this USB.
Please suggest how to resolve this issue.

Read the l4t developer guide document and modify the device tree according to your hardware design.

Thanks for reply.
What is “l4t developer” can you please provide the link?

Pick the version you are using.

Select the Jetson Linux Developer Guide link.

Search “Universal Serial Bus” in the doc and it will lead to you the document for how to configure device tree.

Thank you very much for clarification. This is very helpful.

We have additional query,
As we are using USB micro AB connector in custom board, We tried to remove Type-C support from device tree by deleting below module from i2c@c240000 from “tegra234-p3768-0000+p3767-xxxx-nv-common.dtsi” file,

fusb301@25 {
compatible = “onsemi,fusb301”;
reg = <0x25>;
status = “okay”;
#address-cells = <1>;
#size-cells = <0>;
interrupt-parent = <&gpio>;
interrupts = <TEGRA234_MAIN_GPIO(Z, 1) IRQ_TYPE_LEVEL_LOW>;
connector@0 {
port@0 {
fusb_p0: endpoint {
remote-endpoint = <&typec_p0>;
};

  1. After this change we are unable to flash the SDK. Could you please explain the procedure how to remove Type-C support from device tree.

  2. The link provided in previous reply has example code for AGX module, if you could provide the example for Orin Nano it will be helpful.

You need to remove other node that is related to above typec p0 port as well.

I mean your modifications are not sufficient.

Thanks for the quick reply. We are able to remove the Type-C from device tree and downloaded the SDK on custom board.

Now we have to update the device tree for USB micro AB connector (which has ID pin). So kindly share the steps to configure USB microAB with ID pin.

That document has everything you need. You should read it and try to understand it first.
