TX2 config#4 for USB LANE MAPPING

Autonomous Machines Jetson & Embedded Systems Jetson TX2
1

Hi All:

Our carrier board has three USB3.0 type A port.

I follow the Jetson/TX2 USB - eLinux.org instructions. this is what i have done as below:
1.modify ODMDATA to 0x7090000 to use config#4 USB lane mapping.
2.comment out

[    0.142498] node /plugin-manager/fragment-500-pcie-config match with board >=3310-1000-500
[    0.142936] node /plugin-manager/fragment-500-xusb-config match with board >=3310-1000-500
[    0.143213] node /plugin-manager/fragment-500-e3325-pcie match with board >=3310-1000-500

3.change power tree
Change vbus-2-supply from vdd_usb2_5v to battery_reg. The modifications are as follows:

pinctrl@3520000 {
     vbus-0-supply = <&vdd_usb0_5v>; 
     vbus-1-supply = <&vdd_usb1_5v>;
     - vbus-2-supply = <&vdd_usb2_5v>;
     + vbus-2-supply = <&battery_reg>; 
     vbus-3-supply = <&battery_reg>; 
     vddio-hsic-supply = <&battery_reg>;
     avdd_usb-supply = <&spmic_sd3>;
     vclamp_usb-supply = <&spmic_sd2>;
     avdd_pll_erefeut-supply = <&spmic_sd2>;
  };

I try to modify kernel-dts/tegra186-quill-p3310-1000-c03-00-base.dts file to enable USB3.0 for three of them, and get the following result.

4.change device tree

            nvidia,port-cap = <TEGRA_PADCTL_PORT_HOST_ONLY>;
        };
    };
};

then i flash the dtb to target board

sudo ./flash.sh -r -k kernel-dtb jetson-tx2 mmcblk1pl

then i use the command dmesg | grep usb

just one usb 3.0 is work now.
can anyone give me some advice?
thanks a lot.

The shematic connect pin as follows

[USB3 typeA]
USB1_D (A38, A39)
USB_SS (C43, C44, F43, F44)

[USB3 typeA]
USB2_D (B42, B43)
USB_SS (D42, D43, G42, G43)

[USB3 typeA]
USB0_D (B39, B40)
USB_SS (D39, D40, G39, G40)

my question is :
what’s mean by

[    4.199515] tegra186-padctl 3520000.pinctrl: invalid group "usb3-0" for function "xusb"
[    4.208476] tegra186-padctl 3520000.pinctrl: invalid group "usb3-1" for function "xusb"
[    4.217408] tegra186-padctl 3520000.pinctrl: invalid group "usb3-2" for function "xusb"

and

[    4.948970] xhci-tegra 3530000.xhci: Direct firmware load for tegra18x_xusb_firmware failed with error -2

can anyone give me some advice?
thanks a lot.

Hi,
Please check adaptation guide. There are two versions. One is for r28 and the other is for r32.
[r28]
https://developer.nvidia.com/embedded/dlc/l4t-driver-package-tx2-adaptation-guide
[r32]

head -n 1 /etc/nv_tegra_release

R28 (release), REVISION: 2.1, GCID: 11272647, BOARD: t186ref, EABI: aarch64, DATE: Thu May 17 07:29:06 UTC 2018

jetpack version is:
JetPack-L4T-3.3-linux-x64_b39.run

You don’t need “nvidia,function = “xusb”;” for usb3.0 port.

[    4.948970] xhci-tegra 3530000.xhci: Direct firmware load for tegra18x_xusb_firmware failed with error -2

I am not sure if this is error because you only shared partial log. If xusb fw still not load up after it, then please check if you have usb firmware under /lib/firmware.

thanks for your replay.
[r28] is the version of nvidia kernel?

is r28 is not supoort three usb?

Hi,
r28 means the version in /etc/nv_tegra_release. Yours is r28.2.1.

Two more suggestions:
1 Please run xxd to check correctness of device tree. Here is an example:
https://devtalk.nvidia.com/default/topic/1048285/jetson-tx2/how-to-setup-usb-config-4-for-tx2-l4t-28-2-1-/post/5320806/#5320806
2 Chekc if VBUS is turned on too early:

thanks for your replay .
is r28 is not supoort three usb3.0?
i found the l4t-driver-package-tx2-adaptation-guide is not mention.
just mention
ODMDATA=0x1090000 while flashing for Jetson TX2 for Configuration #2
ODMDATA=0x90000 for Configuration #1
ODMDATA=0x6090000 for Configuration #3

9

It supports. Please calculate the odmdata for #4,5,6 by yourself.

You can find many topics same to your issue on this forum too.

which the relation between tegra186-quill-p3310-1000-a00-00-base.dts and tegra186-quill-p3310-1000-c03-00-base.dts
i follow the article
https://elinux.org/Jetson/TX2_USB
after do that ,my board can not detect any usb 3.0.
then i cd to /sys/firmware/devicetree/base/pinctrl@3520000/pinmux
i found that

the pinmux nodes of device tree is the sum of tegra186-quill-p3310-1000-a00-00-base.dts and tegra186-quill-p3310-1000-c03-00-base.dts
is that right ?

which the relation between tegra186-quill-p3310-1000-a00-00-base.dts and tegra186-quill-p3310-1000-c03-00-base.dts

The c03 base dts includes the a00-base dts. The nodes in c03 are able to override the ones from a00.

For example, if you put one node status to “disabled” in a00 and write it to “enabled” in c03, then result of runtime is “enabled”.

and three usb 3.0 works all.

BTW, pcie should be <2,1,1> instead of <1,1,1>. It has some tricks inside the driver, though it is actually running in 3x1-lane.
