  1. Hardware: NVIDIA Jetson AGX Orin (Thor)
  2. Interface: Integrated QSFP Port (PCIe Device 01:00.0)
  3. Physical Connectivity: Jetson (QSFP) → Fiber Optic Cable → Switch/Media Converter → Copper (RJ45)
  4. Software: Mellanox Software Tools (MST)

We are attempting to reconfigure the network interface on the Jetson AGX Orin (Thor) platform. Our setup requires a fiber optic connection from the Jetson’s QSFP port to a switch, which eventually bridges to a copper-based network.

Although the MST driver set starts successfully and the PCI device is correctly mapped, any attempt to query or modify the device configuration results in a register access failure.

Observed Error:

The command fails with the following error message:

-E- Error when trying to check if NV access registers are supported rc=(524)

Sorry for the late response.
Is this still an issue to support? Any result can be shared?
