Data Sheet

Help! If screen prints Cannot access line '/dev/ttyUSB0', then your Linux user account is not in the

plugdev and/or dialout system group. Ask your system admin to add your account to both groups, and

then restart your computer for it to take effect.

If you see [screen is terminating], it might also be due to the system groups, or there's something else

wrong with screen—ensure all screen sessions are closed (type screen -ls to see open sessions), unplug the

USB cable from the Dev Board, and then try again.

Tip: You can also connect to the board via MDT (only with boards running Mendel 3.0 or higher).

HDMI port

This is a full-size HDMI 2.0a port.

By default, the output is locked at a resolution of 1920 x 1080 to avoid GPU pressure and power costs when driving

higher resolution displays.

If your display does not support 1920 x 1080, you can change this setting by editing file at

/etc/xdg/weston/weston.ini: In the [output] section, edit the line mode=1920x1080 to be a resolution of your choice.

You may also delete this line completely, and it will then use the highest resolution supported by the monitor (but doing

so can degrade the overall system performance if it is higher than 1920x1080).

USB 3.0 ports

There are three USB 3.0 ports:

USB Type-A host: Operates as a USB 3.0 host that can provide power. Use this port for your peripherals, such as a

USB camera.

Caution: Do not connect a device that draws more than 1A of power or you will brownout the system.

USB Type-C data: Operates as a USB "on the go" (OTG) device port, so the Dev Board appears as a USB device to a

connected host device. Use this port to connect to the shell over USB or to flash the board.

USB Type-C power: Use this to power the board with a 2-3A at 5V DC connection.

Ethernet port

The Gigabit Ethernet port (RJ45) supports 10/100/1000Mbps Ethernet/IEEE 802.3 networks.
