Hello,
I tried to pair USB2 P0 and SS P0 to have USB3.0 OTG function on developer kit.
After reading TRM page 1283, I think we may need send USB2 P0 and SS P0 signals to XUSB controller.
My questions are below:
Thanks for any help.
Hi yenyu,
Did you ever check this topic [url]https://devtalk.nvidia.com/default/topic/933330/jetson-tx1/jetson-tx1-usb3-0-otg[/url]/ ? Hope it can help you.
Hi Trumany,
Thank you for your help.
I have followed below topics to configure our device and kernel menuconfig to pair USB2 P0 and SS P1

In host mode, it seems OK.

When I tried to set TX1 as device mode by controlling USB_ID, I got below kernel log.

Then I tried to set TX1 as mass_storage by below commands
I got below error messages:
[ 927.017502] g_mass_storage gadget: Mass Storage Function, version: 2009/09/11
[ 927.017514] g_mass_storage gadget: Number of LUNs=1

Could you give me some ideals to fix this issue?
And I also tried another method to set TX1 as device mode.
https://devtalk.nvidia.com/default/topic/952472/jtx1_usb_as-device/?offset=4
But if I enable CONFIG_USB_G_ANDROID=y in kernel config, TX1 was crashed when booting.
Could you also give me some ideals of this issue?
Thank you very much.
Hi yenyu,
I see you make progress in
[url]https://devtalk.nvidia.com/default/topic/952472/jetson-tx1/jtx1_usb_as-device/post/5033515/#5033515[/url]
So now you have get USB 2.0 otg work but USB 3.0 otg still fails?
Hi DaneLLL,
We was able to set TX1 as an USB 3.0 device successfully.
Thanks.
