Ethernet interfaceEdit
RIALTO SBC has two Ethernet interfaces:
- eth0 on J16 (labelled as Ethernet 1)
- eth1 on J59 (labelled as Ethernet 2)
DescriptionEdit
The Ethernet interfaces are available at the connectors J16 and J59. Primary interface is on J16.
J16 and J59 are a RJ45 shielded connectors with link/activity led.
SignalsEdit
The following table describes the interface signals:

Device mappingEdit
The network interfaces mapped as follows:
- J16 is
eth0device in Linux. - J59 is
eth1device in Linux.
Device usageEdit
The peripherals use the standard kernel interface and network protocol stack.
