Jetson AGX Orin: Support for Recovery Mode via USB Hub on USB3_N/P Interface

I am designing a custom carrier board for the Jetson AGX Orin module and require clarification on the physical pin requirements for entering Force Recovery Mode (RCM).

Based on my reading of the Design Guide, I understand that:

  1. USB 2.0 Recovery is strictly limited to interface USB0_N/P.
  2. USB 3.2 Recovery requires Port #1 on the UPHY_RX1/TX1 pins, paired with USB0_N/P.

My specific question is:

Can we use the USB3_N/P paired with UPHY_RX0/TX0 signals to trigger or perform USB recovery?

Additional Design Context:

In our current carrier board layout, USB3_N/P is connected directly to an on-board USB Hub. We intended to use one of the downstream ports of this hub as the primary “Recovery Port” for end-users to flash the system.

Specific Follow-up Questions:

  1. Hub Compatibility: Does the Jetson AGX Orin’s bootrom/RCM logic support the USB enumeration process through an intermediate hub, or does it require a direct, point-to-point connection to the Host PC?

  2. USB3 Functionality: Is there any internal strapping or configuration that allows USB3_N/P to function as the RCM interface instead of USB0?

Thanks

For this question, the answer is no. You have to use USB0_N/P.

Direct connection is required.
