{{{nome-peripheral}}} interface[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 source]
The {{{nome-peripheral}}} 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-{{{nome-peripheral}}}-connector.png|thumb|center|500px|{{{nome-peripheral}}} connector]]
Signals[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 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 source]
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
