First contact with the board

In this wiki, we are going to follow some steps required for use and interaction with the board from the host machine. As a first step, please connect the microUSB & USB between the board and the host machine in order to connect by a serial protocol.

Install serial application

In this case, we are going to use picocom, and to install it please execute the following command:

sudo apt-get install -y picocom

After turning on the board and issuing the following command you will be able to interact with the board by serial:

sudo picocom -b 115200 /dev/ttyUSB0

Note: the default user for the board is root.

Configuring the ethernet interface for Internet connection on i.MX8M Plus

Before start, please make sure you do not have internet connection:

# Ping to Google's IP
ping 8.8.8.8

If you do not have internet in the board please follow the steps below.

To list the available Network interfaces issue the following command:

ip a

Probably you will have a eth0 interface, so let's configure this interface:

1) Turn on the interface:

ifconfig eth0 up

2) Assign manually an IP:

ifconfig eth0 192.168.x.y

3) Assign the default gateway in your network:

route add default gw 192.168.x.1

4) Test the connection:

# Ping to Google's IP
ping 8.8.8.8
