USB hub didn't work at Jetson AGX Xavier

Hello,

  We designed a carrier board for jetson agx xavier but usb didn't work.
  The following are differences between our carrier board and the demo carrier board. 
  1. We use USB type A funciton.
  2. We usb B55 as USB OTG pin and we connect VBUS_DET to P_3V3 directly. 
  
  We have already tried the solution from the following link but it's not work.

  Please help us to solve this issue, thanks.

Hi,

The usb document for AGX will be released recently. Need your patience for it.

Hi,

Could you please tell us the difference between the following block name ?
XUSB_DEV_BAR0
XUSB_HOST_PF_BAR0_OP
XUSB_HOST_PF_BAR0_RT
XUSB_HOST_PF_BAR0_DB
XUSB_HOST_VF0_BAR0_OP
XUSB_HOST_VF0_BAR0_RT

XUSB_HOST_VF2_BAR0_DB
XUSB_HOST_VF3_BAR0_OP
XUSB_HOST_VF3_BAR0_RT
XUSB_HOST_VF3_BAR0_DB

I found that the label tegra_xhci was on the XUSB_HOST_PF_BAR0_OP and the label tegra_xudc was on the XUSB_DEV_BAR0 but I can’t figure out why. Please help us, thank you.

Please check Xavier TRM.
