Hi WayneWWW

I have a big problem. USB3.0 can not bring up

Direct firmware load for tegra18x_xusb_firmware failed with error -2

Hi aesinfo,

Yes, usb3.0 requires usb2.0 too.
This error indicate the firmware is missing and not related to your topic “USB3.0 Can not bring up without USB 2.0”

Hi WayneWWW
I change some setting in tegra186-quill-p3310-1000-c03-00-base.dts file as below:
I’m not sure white it change setting is correct. Would you help me to check and if you need more information please let me know.

Are you using rel-28 or rel-32?

aesinfo · October 24, 2019, 5:39am

Hi Wayne

We use rel-28

Thank

WayneWWW · October 24, 2019, 5:42am

Then please refer to

If you think your device tree is correct, please share the full dmesg with us.

I saw usb function is up in your side. Could you also share the result of lsusb?

Do you read adaptation guide to configure the ODMDATA before flash?
Your log indicates usb3.0 port is up. Please clarify which port has issue.

aesinfo · October 24, 2019, 8:33am

Hi WayneWWW

I get this message from TX2

tegra-xudc-new 3550000.xudc: usb3 phy is not available yet

aesinfo · October 24, 2019, 8:42am

Hi WayneWWW

Which part in log is showed usb3.0 port is up

thank you

WayneWWW · October 24, 2019, 9:31am

lsusb gives out a 5000M speed usb hub. That means usb 3.0 is up.

aesinfo · October 24, 2019, 9:52am

hi WayneWWW

I understand but i plug-ing USB-3.0 can not detect usb 3.0

WayneWWW · October 24, 2019, 10:18am

Hi aesinfo,

Let me share what is the information needed for checking such issue. USB bring up topics are everywhere on this forum. You could search it too.

The full dts. Not only the partial one.
dmesg. You already shared.
The schematic of your carrier board.
More information from you. For example, there are 3 usb 3.0 ports on your side, do all of them not work? or only one of them? What is the change you’ve made? Did you read adaptation guide about how to configure uphy mapping?

aesinfo · October 29, 2019, 1:40am

Hi WayneWWW

Fix this problem

Thank you
