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
Signals[edit | edit source]
The following table describes the interfaces signals:
- J10
| Pin# | Pin name | Pin Notes |
|---|---|---|
| 1 | ETH0_TXRX1_P | |
| 2 | ETH0_TXRX1_N | |
| 3 | ETH0_TXRX2_P | |
| 4 | ETH0_TXRX3_P | |
| 5 | ETH0_TXRX3_N | |
| 6 | ETH0_TXRX2_N | |
| 7 | ETH0_TXRX4_P | |
| 8 | ETH0_TXRX4_N | |
| 9 | ETH0_LED_ACT | ETH0 has active low signals |
| 11 | ETH0_LED_LINK | ETH0 has active low signals |
- J38
| Pin# | Pin name | Pin Notes |
|---|---|---|
| 1 | ETH1_TXRX1_P | |
| 2 | ETH1_TXRX1_N | |
| 3 | ETH1_TXRX2_P | |
| 4 | ETH1_TXRX3_P | |
| 5 | ETH1_TXRX3_N | |
| 6 | ETH1_TXRX2_N | |
| 7 | ETH1_TXRX4_P | |
| 8 | ETH1_TXRX4_N | |
| 10 | ETH1_LED_ACT | ETH1 has active high signals |
| 12 | ETH1_LED_LINK | ETH1 has active high signals |
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.
