Hi,

I’ve designed a custom carrier board for tx2i. But, I am unable to see USB interfaces in ubuntu. kindly assist.

TIA

What software release are you using ? rel-28 or rel-32?

4

rel-32

5

please refer to the usb porting guide and modify the device tree.

I had referred P2597 carrier board schematics for my custom carrier board. There is only one USB 3.0 Port & one USB 2.0 Port in the custom board. The document mentions that by default the carrier board will be config 2. Do I still need to update the device tree?

7

Even changing the power source requires to change the device tree.

8

Oh, I am new to this. I have currently designed the carrier board with 1x USB3.0, 1xUSB2.0, 1x UART, 1x ethernet, 2 x 2 lane MIPI CSI2, 1 x RS422, 1 x RS232, 2 X I2C, 1 X JTAG along with auto power on. Could you please assist in configuring the device tree for these interfaces.

TIA

I already shared the document. Read it first and share us what is the part that you cannot understand.

If possible, find a software engineer who is familiar with linux kernel to co-work with you.

ok

As per the requirements of the custom carrier board the following changes were made in the device tree

  1. gpio@74 {
    compatible = “ti,tca9539”;
    status = “disabled”;
  2. pinctrl@3520000 {
    compatible = “nvidia,tegra186-xusb-padctl”;
    reg = <0x0 0x3520000 0x0 0x1000 0x0 0x3540000 0x0 0x1000>;
    reg-names = “padctl”, “ao”;
    resets = <0x10 0x37>;
    reset-names = “padctl_rst”;
    clocks = <0x10 0x6f 0x10 0x215 0x10 0x87 0x10 0x86>;
    clock-names = “xusb_clk”, “utmipll”, “usb2_trk”, “hsic_trk”;
    interrupts = <0x0 0xa7 0x4>;
    mboxes = <0xb5>;
    mbox-names = “xusb”;
    #phy-cells = <0x1>;
    status = “okay”;
    vbus-0-supply = <0x26>;
    vbus-1-supply = <0x26>;
    vbus-2-supply = <0x26>;
    vbus-3-supply = <0x26>;

However, inspite of above changes USB enumeration isn’t happening in Ubuntu. Please find the responses below and kindly assist.
