1 Overview[edit]

This stage explains how to connect the Linux terminal of your board to your host computer through the ST-LINK/V2-1.
Then you can see how to execute basic commands with the Linux command line interface in order to be familiarized with the Linux console.

2 The serial terminal[edit]

The serial terminal allows you to communicate with the board trough an UART serial interface.

  • Install minicom
PC $> sudo apt-get install minicom
  • Get the ttyACM device instance that needs to be used to access the ST-LINK/V2-1
PC $> ls /dev/ttyACM*
/dev/ttyACM0
  • Connect the minicom to the /dev/ttyACM0 device
PC $> minicom -D /dev/ttyACM0
Welcome to minicom 2.7

OPTIONS: I18n 
Compiled on Nov 15 2018, 20:18:47.
Port /dev/ttyACM0, 15:56:03

Press CTRL-A Z for help on special keys
  • Press the reset button to reset the board. You should see logs displayed in the minicom window
