Hello,
Our carrier board with L4T 35.0.9 use RTL8211FSI-CG can not work.
The eth0 can be found by ifconfig, the value of RX packages changes by every ifcnofig, but the TX does not. Could you please share your comments here ?

There has the file in the attachment whose name is “test environment.png”, you can know the test hardware environment.

And “gpu_sch.pdf” is the schematic for GPU module and two PHYs that are described in “test environment.png”.

And also put related the device tree files in the attachment.

Finally, I also put the console log from GPU module in the attachment.

Hi, this kind of design (two PHYs with same MDIO) is not in our support range. Please check with vendors to review your design and refer to the Orin DG and the checklist sheet attached in the DG to check your design.
