Build

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' for minimal, console-only image and for simple X11 image
           'rpb-wayland' for Wayland/Weston image

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.

Build a minimal, console-only image

$ bitbake rpb-console-image

At the end of the build, your build artifacts will be found under tmp-eglibc/deploy/images/dart-sd410/.
The two artifacts you will use to update your board are: rpb-console-image-dart-sd410.ext4.gz and boot-dart-sd410.img

Build a simple X11 image

$ bitbake rpb-desktop-image

At the end of the build, your build artifacts will be found under tmp-eglibc/deploy/images/dart-sd410/.
The two artifacts you will use to update your board are: rpb-desktop-image-dart-sd410.ext4.gz and boot-dart-sd410.img

Build a Wayland/Weston image

$ bitbake rpb-weston-image

At the end of the build, your build artifacts will be found under tmp-eglibc/deploy/images/dart-sd410/.
The two artifacts you will use to update your board are: rpb-weston-image-sd410.ext4.gz and boot-dart-sd410.img

Extract the needed image from .gz archive.

$ gunzip rpb-desktop-image-dart-sd410.ext4.gz

This command will create a new file with ext4 extension. This file will be used to flash the rootfs partition on the target device.

Edit flashall script

If the needed image is not rpb-desktop-image-dart-sd410 then you will need to edit the script to follow the needed image. Use text editor to change the name of the rootfs file in the flashall script.

$ gedit flashall
