OpenEmbedded

This page provides the Dragonboard820c specific instructions for flashing OpenEmbedded images. For instructions on building the OE images, please refer the generic OpenEmbedded guide.

Updating UFS partitions and Bootloader

To make sure that the UFS partitions and Bootloader is up to date follow our Board Recovery Guide

Install fastboot

You will use the Android fastboot utility on your development host for managing the board's UFS partitions. If you are using a relatively recent Linux distribution on your development host, it probably already has a package that includes the fastboot utility (it might be named something like android-tools or android-tools-fastboot) so go ahead and install it on your development host.

Flashing build artifacts

At the end of any successful build you will end up with the following artifacts (amongst others)

  • IMAGE-dragonboard-820c.ext4.gz and
  • boot-dragonboard-820c.img

Note: Replace IMAGE with the name of image you built. For example, if you built rpb-console-image then IMAGE will be rpb-console-image

These will be found in your tmp-rpb-glibc/deploy/images/dragonboard-820c directory.

After getting into fastboot mode, following commands can be used to flash built images onto Dragonboard820c's UFS.

$ gunzip IMAGE-dragonboard-820c.ext4.gz
$ sudo fastboot flash boot boot-dragonboard-820c.img
$ sudo fastboot flash system IMAGE-dragonboard-820c.ext4
