Ethernet interfaces[edit | edit source]
The Evaluation Kit features two Gigabit Ethernet interfaces:
- ETH0 on J10 (labelled as Ethernet 1)
- this interface also features the TSN functionality
- ETH1 on J38 (labelled as Ethernet 2)
Description[edit | edit source]
The Ethernet interfaces are available on the Evaluation Kit at the connectors J10 and J38. Primary interface is on J10.
J10 and J38 are a RJ45 shielded connectors with dual led. J10 is connected to the SoM Ethernet PHY, J38 is connected to the Carrier Ethernet PHY

Device mapping[edit | edit source]
The network interfaces mapped as follows:
- J10 is
eth0device in Linux. - J38 is
eth1device in Linux.
Device usage[edit | edit source]
The peripherals use the standard kernel interface and network protocol stack.
