USB ports not working on custom carrier board.

After reading several posts on the forum. I have understood that reconfiguration is required in custom carriers to enable it.

Can anyone share the procedure for

  1. Enable USB 2.0 ports
  2. Configure PCIe and USB3.0

I am using JetPack3.0 and L4T 28.1.

contact your carrier board manufacturer for drivers /support

Hi vishwanath.nm,

You need to know the USB configuration for lane mapping, then make the suitable change of device tree.
Please refer to the Jetson TX2 Platform Adaptation and Bring-Up Guide .


hi kaycc

Jetson TX2 Platform Adaptation and Bring-Up Guideis for USB3.0/PCIe configuration selection.

What about the USB 2.0 ports not working?

I tried the solution according to but this did not help.

I am not suspecting the hardware as port 1 is working but port 0 and 2 are not.

An example for your reference:
