1. Overview[edit | edit source]
This step explains how to connect your host Linux® terminal to your host computer through the ST-LINK/V3EC (see STM32MP215x-DKx_-_hardware_description#Board_overview).
It then describes how to execute basic commands with the Linux command line interface in order to order to get familiar with the Linux console.
2. Serial terminal[edit | edit source]
The serial terminal allows communicating with the board through 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/V3EC
ls /dev/ttyACM* /dev/ttyACM0 /dev/ttyACM1
- Connect the minicom to the /dev/ttyACM0 device
minicom -D /dev/ttyACM0 Welcome to minicom 2.8 OPTIONS: I18n Port /dev/ttyACM0, 15:56:03 Press CTRL-A Z for help on special keys
- Press the reset button to reset the board. The boot log should be displayed on the minicom window:
