How-to-EVB-LAN8670-USB

Note: Keep this application note in mind when building for Debian based systems. You may need to revert back to legacy network configuration tools.

  • Disconnect EVB-LAN8670-USB, if it is already connected.
  • Build kernel driver:
cd extras/evb-lan8670-usb-linux-6.1.21
make
  • Load kernel driver:
sudo insmod microchip_t1s.ko enable=1 node_id=0 node_count=8 max_bc=0 burst_timer=128 to_timer=32
  • dmesg output when connecting the USB dongle:
[  +0,124736] usb 1-2.3: New USB device found, idVendor=184f, idProduct=0051, bcdDevice= 2.00
[  +0,000016] usb 1-2.3: New USB device strings: Mfr=1, Product=2, SerialNumber=3
[  +0,000006] usb 1-2.3: Product: 10BASE-T1S

[  +0,000176] LAN867X Rev.B1 usb-001:025:00: attached PHY driver (mii_bus:phy_addr=usb-001:025:00, irq=190)

  • Configure IP address for eth1: (Note: it could also be another eth interface, you need to check and compare MAC address against dmesg output).
sudo ip addr add dev eth1 192.168.42.100/24
  • You can take a look at the registered Ethernet device via ip link show eth1:
3: eth1: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc fq_codel state DOWN group default qlen 1000
    link/ether 3c:e1:a1:b8:e9:76 brd ff:ff:ff:ff:ff:ff
    inet 192.168.42.100/24 scope global eth1
       valid_lft forever preferred_lft forever
  • Bring eth1 interface up via sudo ifconfig eth1 up.
  • Verify eth1 via ifconfig eth1:
eth1: flags=4099<UP,BROADCAST,MULTICAST>  mtu 1500
        inet 192.168.42.100  netmask 255.255.255.0  broadcast 0.0.0.0
        ether 3c:e1:a1:b8:e9:76  txqueuelen 1000  (Ethernet)
        RX packets 0  bytes 0 (0.0 B)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 0  bytes 0 (0.0 B)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0
