Synchronize your source code
Source code you have is one week old now. So, first step is synchronize it.
$ repo sync
Create your local branch
$ repo start <new branch name> --all
Why should I create a local branch?
If you change *any* source code (for choosing another preferred kernel, for example) and want to sync again, or use master instead of dylan, you may be able to rebase or sync your source code, even with changes.
Or you found a bug, fixed that, and want to send a patch to community.
Choose your board
$ source setup-environment build
Now, you are in new created build directory.
The default board for dora is imx6qsabresd, you can choose QSB or imx28 if you prefer:
$ vi conf/local.conf
Your default local.conf file can looks like:
MACHINE ??= 'imx6qsabresd'
DISTRO ?= 'poky'
PACKAGE_CLASSES ?= "package_rpm"
EXTRA_IMAGE_FEATURES = "debug-tweaks"
USER_CLASSES ?= "buildstats image-mklibs image-prelink"
PATCHRESOLVE = "noop"
BB_DISKMON_DIRS = "\
CONF_VERSION = "1"
BB_NUMBER_THREADS = '4'
PARALLEL_MAKE = '-j 4'
ACCEPT_FSL_EULA = ""
Change MACHINE to your board name. In order to figure out what is your machine name:
$ ls ../sources/meta-fsl-arm/conf/machine/*.conf -l

Now you know every supported board.
For other supported board, take a look on Freescale/meta-fsl-arm-extra · GitHub
Or, see the meta-fsl-arm:dora release notes: Freescale Community BSP Release Notes 1.5 documentation
Start to build
The biggest image from meta-fsl-demos is fsl-image-gui. It has X11, gstreamer, fsl codec for gstreamer, unit-test, gpu, one gpu sample (with source code) for imx53 and QT 4.8. But it takes forever to build (if you are luck and have a powerful machine, it will take only few hours). In my PC it takes around 4,5 hours to complete (from scratch) at first time. If you have already built it once, it will take 3 seconds to decide nothing has been changed and about 15 minutes to wrap the image (it´s a 750MB rootfs, and it does take some time to create such big file)
But there is a lot of other images you can create. In order to see how many, please:
$ find ../sources -name *image*
I would say, start core-image-base. It does not have X11 or gstreamer or QT, but it take 30 minutes to build at first time. And should work great for any board.
Following, the complete sequence of commands, it´s only to make sure you´re on the right folder:
(you are still in build directory)
$ bitbake core-image-base
Note (24Feb2014): Required disk space for build image is ~18GB
