Ethernet and Serial ports on We are using the Jetson AGX Orin Developer Kit

We are using the Jetson AGX orin developer kit. As far as I understand it, the Jetson AGX Orin has two Ethernet interfaces:

  • 1x GbE: RGMII
  • 1× 10GbE: MGBE by XFI

But only the 10GbE interface is exposed on the developer kit. Is it possible to somehow access the second Ethernet interface on the developer kit?

Also, is the UART5/RS-232 on the 40-Pin Connector the only serial interface available on the developer kit?

Thanks for your help.

hello damien.bardon,

please access Jetson AGX Orin Series Design Guide for ethernet and uart chapter.
BTW, there’re five UARTs available. that’s UART1 on pin-8 for 40-pin expansion header.

You can make your own custom board for RGMII interface. The developer guide document also has gudiance for what is needed to change in device tree to bring up RGMII.

Thank you for your response. To clarify, I understand that the AGX module has an RGMII interface, but I was wondering if this interface is available on the Developer Kit?

Not available on devkit.
