I‘m sorry ,The problem is still unresolved,this is the dmesg log, please help me see
the main error:

Maybe you should tell some detail about your board design and what efforts you have tried in your device tree.

Please don’t expect other people can easily understand your problem by just few words or brief log.

The board design is based on the official website documents ,and I tried to follow some posts to modify the dts file “tegra186-quill-p3310-1000-a00-00-base.dts”:
pinctrl@3520000 {
vbus-0-supply = <&vdd_usb0_5v>;
vbus-1-supply = <&vdd_usb1_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>;
};
but , Still have the same problem ,usb not work

You should follow the adaptation guide first, if you cannot tell the correctness of those posts.

this is dmesg log ,thanks

7

Adaptation guidelines are also these methods ，I have seen

8

Which adaptattion guide are you referring to? Which jetpack release are you using?

jetpack 4.3

Tegra_Linux_Driver_Package_TX2_Adaptation_Guide.pdf (548.8 KB)
sorry ，Should be this

11

Did you ever read “Porting USB (Universal Serial Bus)” section? That is the one you should check.

excuse me ,in the" jetson TX2 Platform Adaptation and bring-up Guide "document,Figure 7 USB OTG ID pins,not use the USB0_VBUS_DET on my custom board , See the uploaded image for details,not using this pin ,if that would be a problem?

13

You can follow the document to write your own extcon status table to control this port without the ID pin.

14

My colleague checked the“Porting USB”，Didn’t find anything，all follow the document,so I don’t know what could be the reason, First time using TX2, not familiar with it

15

This table from the document is the extcon table.If there is no USB0_VBUS_DET in use on your port, then write a new table for your usecase.

This is standard linux kernel driver. Not NV use only.

ok,thanks,and look the dmesg log USB is not powered up, I don’t know if it is related to hardware or software

17

Then you can share the dmesg, board schematic and current dts files. We are not your co-worker, so know nothing about your board.
There were lots of users also saying “our board is based on official document”, but turns out the cases are different.
