Serial port
VT-SOM-I500P-EVB implements 3 UART connectors, including UART1, UART 2-1 and UART
2-2 that correspond to nodes ttyS1, ttysWK0, and ttysWK1.
Connect a serial port that you intend to use to the host PC via a TTL to USB adapter before
testing the port.
1.
Input the node of the serial connector to enable serial communication (e.g., UART1);
# uart_active /dev/
ttyS1
2.
Send data (“TEST”) to the serial port and receive the data.
# echo
TEST
> /dev/
ttyS1
# cat /dev/
ttyS1
