How to connect to your brand new Mango? There are a couple of ways to do this and we do recommend:
Serial connectivity is available via pins connection. Pins on block J18 (1 - 3.3V, 2 - UART_TXD, 3 - UART_RXD, 4 - GND) designed for serial/console connection. Also, you need UART - USB adapter to connect a console to your computer.
Simply run the program, enter a COM port number, select the baudrate 115200 and click "connect".
Just run picocom with 115200 bps and a serial interface parameter. Your serial device might be named /dev/ttyUSB[n] where [n] is your serial id set by your operating system.
$ picocom -b 115200 /dev/ttyUSB0
You can check your available serial devices with this command:
$ ls /dev/ttyUSB*
To exit from picocom press CTRL+a+x.
