==USB interface ports == ''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''

The USB interface available on the Evaluation Kit at the connector ''TBD:Jxxx''.  ''Jxx'' * J16 is a ''TBD:connectormicro-AB type'' header connector receptacle for the RS232 two-wires UART3 port, used for debug purposes a USB OTG connection: this interface can operate in Host mode and Device (bootloader and operating system serial consoleperipheral). mode

UART3 is mapped to <code>/dev/ttymxc2</code> device in Linux. The peripheral is USB Host port can be used as the default serial console, both under Linux for connecting USB peripheral devices: the bootloader and related peripheral driver has to be integrated into the Linux 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
