==Power Supply interface ==
 
''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 ===
The Power Supply interface is available on the Evaluation Kit at the SBC connector ''TBD:Jxxx''J68.
''Jxx'' J68 is a ''TBD:connectortwo pins MSTBA 2.5/2-G-type'' header 5.08 Phoenix connector for the RS232 two-wires UART3 port, used for debug purposes (bootloader and operating system serial console).

=== Device mapping ===
UART3 is mapped to <code>/dev/ttymxc2</code> device in Linux. The peripheral is used as the default serial console, both for the bootloader and the kernel.
 
=== Device usage ===
 
To connect to the debug serial port:
 
# connect the DB9 adapter bracket to the J22 connector on the SBCX board
# connect a serial cable between DB9 connector 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
