==Ethernet interface ==
RIALTO SBC has two Ethernet interfaces:
* eth0 on J16 (labelled as '''Ethernet 1''')
* eth1 on J59 (labelled as '''Ethernet 2''')
''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 ===
=== Description ===The Ethernet interfaces are available at the connectors J16 and J59. Primary interface is on J16.
The Ethernet interface available on the Evaluation Kit at the connector ''TBD:Jxxx''J16 and J59 are a RJ45 shielded connectors with link/activity led.
''Jxx'' is a ''TBD[[File:RIALTO_SBC-Ethernet0-connector.png|thumb|center|500px|Ethernet 1 -type'' header J16 connector for the RS232 two-wires UART3 port, used for debug purposes (bootloader and operating system serial console).]]

===Signals ===
The following table describes the interface signals:

=== Device mapping ===
UART3 The network interfaces mapped as follows:* J16 is mapped to <code>/dev/ttymxc2eth0</code> device in Linux. The peripheral * J59 is used as the default serial console, both for the bootloader and the kernel<code>eth1</code> device in Linux.
=== Device usage ===
To connect to The peripherals use the debug serial port: # connect the DB9 adapter bracket to the J22 connector on the SBCX board# connect a serial cable between DB9 connector standard kernel interface and PC COM port through a NULL-modem cable (not provided)# start your favorite terminal emulator software on PC (eg: PuTTY); communication parameters are: 115200,N,8,1 ----network protocol stack.
