hi,
I have a problem regarding USB2.0 on my tx2 custom base board.

The usb 2.0 don’t work,the usb2.0 power is not open.

The boot display is as follows：

please give me some advice.

Please read TX2 adaptation guide.

3

According to the TX2 adaptation guide description ,we should define a new name for our custom board,why ?And can we define a arbitrary name, as long as it conforms to the naming rules?

4

Please just refer to the USB porting part in adaptation guide.

5

I keep the USB2.0 part the same as P2597, The three sets of USB3.0 signals USB1_D_N/USB1_D_P,USB3_RX1_N/USB3_RX1_P,USB3_TX1_N/USB3_TX1_P are connected to the USBHUB chip TUSB8041, and the enabling signal USB_VBUS_EN1 signal is suspended, so do I need to redefine the name of the custom board?

I cannot give you a “yes” or “no” reply for sure. According to your log, there is something wrong when usb pad ctrl initialization. Normally, such issue leads to sw configuration in device tree.

You should share the full dmesg (please attach it as a file, otherwise the log paste will be truncated), and also the schematics.

Please also tell us what is your release.

You could also search similar topics on forum.

Thank you for your help.
The display of the screen at startup is shown as the picture in the attachment, and the schematic is shown as the PDF file in the attachment.The log file is also attached
Please help me and point out the problem.

Please reply the dmesg instead of syslog.

The attached file is the display information of dmesg.

Do you connect the VDD_VBUS directly to the system power? Are you using any gpio to control it?

11

The VDD_VBUS of USB2.0 is converted by APL3511CBL-TRG, which is controlled by GPIO port USB_VBUS_EN0.USB3.0 is connected to the USBHUB chip TUSB8041, which has its own circuit and is powered by the same VDD_5V0_IO_SYS power network as USB2.0, but the GPIO port USB_VBUS_EN1 is not used,leaving it suspended.There are specific circuits in the attached file “usb2.0 and usb3.0. PDF”, .

12

  1. Please refer to adaptation guide “For an OTG (On-The-GO) Port” part and see if anything is missing on your design.

  2. Did you modify anything in your device tree before?

13

I didn;t modify anything in my device tree before.

14

I have checked my designed with “For an OTG (On-The-GO) Port” part and found nothing missing .And here is the attachment is my design around OTG funtion block.Please if possible, help me find where goes wrong which will help me a lot in many ways.Also thanks you for your replaying.PS. the OTGpart is in Page 4.

15

Unless your wiring is a 100% exact match to the development kit reference carrier board you will need to modify the device tree. The device tree tells the SoC which pin is routed to where. Is your carrier board an exact match in schematic to the development kit?

16

My carrier board isn’t exact match in schematic to the devlopment kit,but the part of otg port is exact match to de development kit.Why this part is not work?

You could try to add some debug messages in below function

kernel-4.9/drivers/phy/tegra/xusb.c

->static int tegra_xusb_setup_ports(struct tegra_xusb_padctl *padctl)

and see which case hits the error.

Please be aware that you may still need to change dts as linuxdev’s comment #15. For example, in your schematics, it seems only one micro AB usb port exists on your board. But there are 3x usb2.0 ports on devkit, if you don’t need 3 ports on your board, then please remove redundant ports from your dts.

18

Thanks for your help.
I add some debug messages in below function
kernel-4.9/drivers/phy/tegra/xusb.c

The following information is displayed on the screen after boot
of_property_read_u32 -22

What’s causing this, and how should I change the code

19

There are 5 “of_property_read_u32” in this file.
Please at least tell us which function prints this error. Nobody can tell what goes wrong if you just told us one line.

20

Thanks for your help.
In file “kernel-4.9/drivers/phy/tegra/xusb.c”,the function “tegra_xusb_setup_ports” calls function “tegra_xusb_add_usb2_port”, function “tegra_xusb_add_usb2_port” calls function “tegra_xusb_usb2_port_parse_dt”, and the result ERR is equal to -22 on line 613 of function “tegra_xusb_usb2_port_parse_dt”, and the return value is -517 on line 621 of function “tegra_xusb_usb2_port_parse_dt”.
What’s causing this, and how should I change the code.
