1. Overview[edit | edit source]
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 | edit source]
The serial terminal allows you to communicate with the board trough an UART serial interface.
- Install minicom
sudo apt-get install minicom
- Get the ttyACM device instance that needs to be used to access the ST-LINK/V2-1
ls /dev/ttyACM* /dev/ttyACM0
- Connect the minicom to the /dev/ttyACM0 device
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

- Get the IP address of your board
ip addr show eth0 3: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group default qlen 1000 link/ether 00:xx:xx:xx:xx:xx brd ff:ff:ff:ff:ff:ff inet xx.xx.xx.xx/22 brd xx.xx.xx.xx scope global dynamic eth0 valid_lft 159045sec preferred_lft 159045sec inet6 xx::xx:xx:xx:xx/64 scope link valid_lft forever preferred_lft forever
- On the host computer connect the terminal to the board using ssh
ssh root@xx.xx.xx.xx
root@stm32mp1:~#
