Ethernet interface[edit | edit source]
TBD: sostituire le sezioni con le informazioni sull'uso della periferica e del suo connettore Nell'esempio di seguito c'è la descrizione dell'interfaccia UART/console
Description[edit | edit source]
The Ethernet interface available on the Evaluation Kit at the connector J5.
J5 is a standard RJ45 connector connected to the SOM integrated ethernet controller and PHY.
J6 and J7 connectors are pin-to-pin compatible mounting options for the same interface.

Signals[edit | edit source]
The following table describes the interface signals:
| Pin# | SOM Pin# | Pin name | Pin function | Pin Notes |
|---|---|---|---|---|
| 3 | J18.19 | ETH_TX_P | Transmit data + | |
| 5 | J18.21 | ETH_TX_M | Transmit data - | |
| 6 | J18.23 | ETH_RX_P | Receive data + | |
| 8 | J18.25 | ETH_RX_M | Receive data - | |
| 2,11 | J18.13 | ETH1_LED | Eth link or activity led |
Device mapping[edit | edit source]
This network interface is mapped at eth0 device in Linux.
Device usage[edit | edit source]
The peripheral is used the standard kernel interface and network protocol stack.
