Auvidea M20E M.2 10GbE Ethernet

The Auvidea M20E is an M.2 (M-key) 10 Gigabit Ethernet adapter. It uses the Realtek RTL8127 chipset. Since it occupies the M.2 slot normally used by the NVMe drive, the Jetson must boot from a USB drive instead.

Prerequisites

  • Auvidea M20E M.2 10GbE adapter
  • USB thumb drive (for booting the Jetson OS)
  • ARK Jetson carrier board with M.2 M-key slot

Step 1: Flash to USB Drive

Flash the ARK kernel image onto a USB thumb drive instead of NVMe:

./flash.sh --usb

Step 2: Install the M20E

  1. Remove the NVMe drive from the M.2 M-key slot
  2. Install the Auvidea M20E adapter in its place
  3. Boot the Jetson from the USB drive

Step 3: Install Realtek RTL8127 Driver

The RTL8127 driver is not included in the default kernel. Install it on the Jetson after booting:

sudo apt install build-essential dkms

Download the driver from Realtek:

Build and install:

tar xf r8127-11.015.00.tar.bz2
cd r8127-11.015.00/
make
sudo make install
sudo depmod -a
sudo modprobe r8127

The 10GbE interface should now appear in ip link. You can verify with:

ip link show
ethtool <interface_name>
