DWM 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 DWM interface available on the Evaluation Kit at the connector TBD:Jxxx.

Jxx is a TBD:connector-type header connector for the RS232 two-wires UART3 port, used for debug purposes (bootloader and operating system serial console).


[[File:{Template:Nome-som-EVB-DWM-connector.png|thumb|center|500px|DWM connector]]

Signals[edit | edit source]

The following table describes the interface signals:

Pin# SOM Pin# Pin name Pin function Pin Notes
1,2,4,6,,7,8,10 - N.A. N.C. Not connected
3 J1.189 RS232_RX Receive line
3 J1.187 RS232_TX Transmit line
9 - DGND Ground

Device mapping[edit | edit source]

UART3 is mapped to /dev/ttymxc2 device in Linux. The peripheral is used as the default serial console, both for the bootloader and the kernel.

Device usage[edit | edit source]

To connect to the debug serial port:

  1. connect the DB9 adapter bracket to the J22 connector on the SBCX board
  2. connect a serial cable between DB9 connector and PC COM port through a NULL-modem cable (not provided)
  3. start your favorite terminal emulator software on PC (eg: PuTTY); communication parameters are: 115200,N,8,1
