VT-SBC-3588 | User Manual 32
This chapter is mainly about the first-use debugging of interfaces and software applications.
You can connect a key board, a mouse and a display to the VT-SBC-3588 and debug the
Board directly in the console, or, you can use a USB Type-A to Type-C cable to connect the
Board to a host computer for remote debugging.
Please execute all commands with the root privilege (Ubuntu system password: 123456,
Debian system password: NA).
3.1
Serial connectors
The VT-SBC-3588 offers two RS232/RS485 connectors on the Phoenix terminal (UART4 and
UART7), corresponding to nodes /dev/ttyS7 and ttyS4, respectively. There are another 4
serial connectors (UART8, UART0, UART3 and UART1) on the Board, corresponding to
nodes /dev/ttyS8, /dev/ttyS0, /dev/ttyS3, and /dev/ttyS1, respectively.
To test if the serial ports function properly, use a USB-to-serial adapter to connect a serial
port and the host computer first, then use a serial communication program to check if the
serial port functions properly.
Alternatively, you can cross connect any two serial ports (TX-RX, RX-TX, GND-GND) and use
one for transmitting data and the other for receiving data via a serial communication
program. This allows you to input the commands directly in the console.
The latter case is based on the fact that the Board is running Debian/Ubuntu system. If the
Board is running Android system, please remember to connect it to the host computer and
execute the commands on the host computer. Debian system is used here for illustration.
To test the serial functions, follow the steps below:
UART8
(ttyS8)
UART0
(ttyS0)
UART3
(ttyS3)
UART1
(ttyS1)
UART7
(ttyS7)
UART4
(ttyS4)
