This section will help you enable the HDMI display in the board in the case you installed on the board the LU image with Thundercomm SDK as in the following section Generate image and Flashing with Thundercomm SDK, otherwise, you can skip this section.
You will need to access the board with ADB, if you haven't installed ADB in your host PC, follow step 2 in the section Linaro-Getting Started, and if you want to know how to connect to the board with ADB, read the section Using ADB skipping step 4, before continuing. Follow these steps every time you reboot the board:

3. Type the following commands to enable HDMI display:

# mkdir -p /usr/bin/weston_socket
# export XDG_RUNTIME_DIR=/usr/bin/weston_socket
# export LD_LIBRARY_PATH=/usr/lib:/usr/lib/aarch64-linux-gnu/
# weston --tty=1 --connector=29 --idle-time=0

You should now see the display in your monitor.
