| Let's start | Develop on Arm® Cortex®-A7 | |||||||
|
Unpack the board | 
|
Populate the target and boot the image |
|
Execute basic commands |
|
Use the demo launcher | 
|
1. Overview
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
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
