Select Target Machine

$ source setup-environment
You will be prompted to choose the target machine, pick dart-sd410
You will be prompted to choose the distro, choose:

           'rpb-wayland' for Wayland/Weston image
           'rpb-eglfs' for QT over EGLFS

The script setup-environment will create sane default configuration files in /conf, you can inspect them and modify them if needed.
Note that conf/local.conf and conf/bblayers.conf are symlinks.

NOTE:
When running the setup-environment script, you were asked to read/accept the Qualcomm EULA.
The EULA is required to access the proprietary firmware, such as the GPU firmware , WLAN, ...

If you accepted the EULA, when building an image for DART-SD410 all proprietary firmware are installed automatically in /lib/firmware,
and a copy of the EULA is added as '/etc/license.txt`.

If you did not accept the EULA, the firmware are not downloaded, and not installed into the image.
