<para>
|

Once you have set up the Yocto Project and installed the
|
|
Toaster system dependencies as described in
|
|
"<link linkend='toaster-manual-start'>Preparing to Use Toaster</link>",
|
|
you are ready to start Toaster.
|
|
</para>
|
|
|
|
<para>
|
|
Navigate to the root of your
|
|
<ulink url='&YOCTO_DOCS_REF_URL;#source-directory'>Source Directory</ulink>
|
|
(e.g. <filename>poky</filename>):
|
|
<literallayout class='monospaced'>
|
|
$ cd poky
|
|
</literallayout>
|
|
Once in that directory, source the build environment script:
|
|
<literallayout class='monospaced'>
|
|
$ source oe-init-build-env
|
|
</literallayout>
|
|
Next, from the build directory (e.g.
|
|
<filename>poky/build</filename>), start Toaster using this
|
|
command:
|
|
<literallayout class='monospaced'>
|
|
$ source toaster start
|
|
</literallayout>
|
|
You can now run your builds from the command line, or with
|
|
Toaster as explained in section
|
|
"<link linkend='using-the-toaster-web-interface'>Using the Toaster Web Interface</link>".
|
|
</para>
|
|
|
|
<para>
|
|
To access the Toaster web interface, open your favorite
|
|
browser and enter the following:
|
|
<literallayout class='monospaced'>
|
|
http://127.0.0.1:8000

<title>Setting a Different Port</title>
|
|
|
|
<para>
|
|
By default, Toaster starts on port 8000.
|
|
You can use the <filename>WEBPORT</filename> parameter to
|
|
set a different port.
|
|
For example, the following command sets the port to "8400":
|
|
<literallayout class='monospaced'>
|
|
$ source toaster start webport=8400
|
|
</literallayout>
|

<section id='setting-up-external-access'>
|
|
<title>Setting up External Access</title>
|
|
|
|
<para>
|
|
By default, Toaster binds to the loop back address
|
|
(i.e. localhost), which does not allow access from
|
|
external hosts. To allow external access, use the
|
|
<filename>WEBPORT</filename> parameter to open an
|
|
address that connects to the network, specifically the
|
|
IP address that your NIC uses to connect to the network.
|
|
You can also bind to all IP addresses the computer
|
|
supports by using the shortcut
|
|
"0.0.0.0:<replaceable>port</replaceable>".
|
|
</para>
|
|
|
|
<para>
|
|
The following example binds to all IP addresses on the
|
|
host:
|
|
<literallayout class='monospaced'>
|
|
$ source toaster start webport=0.0.0.0:8400
|
|
</literallayout>
|
|
This example binds to a specific IP address on the host's
|
|
NIC:
|
|
<literallayout class='monospaced'>
|
|
$ source toaster start webport=192.168.1.1:8400
|
|
</literallayout>

<title>The Directory for Cloning Layers</title>

<para>
|

Toaster creates a <filename>_toaster_clones</filename>
|

directory inside your Source Directory
|
|
(i.e. <filename>poky</filename>) to clone any layers
|
|
needed for your builds.

<para>

Alternatively, if you would like all of your Toaster related
|
|
files and directories to be in a particular location other than
|
|
the default, you can set the <filename>TOASTER_DIR</filename>
|
|
environment variable, which takes precedence over your current
|
|
working directory.
|
|
Setting this environment variable causes Toaster to create and use
|
|
<filename>$TOASTER_DIR./_toaster_clones</filename>.

to edit Toaster configuration parameters.
|

To access the Django administration interface, you must

recommended, to set up the Toaster system dependencies,

you need be sure the local user path is in your

<filename>PATH</filename> list.
|

To append the pip3 local user path, use the following

Creating a superuser allows you to access the Django administration

interface through a browser.

The URL for this interface is the same as the URL used for the
|

Toaster instance with "/admin" on the end.
|

For example, if you are running Toaster locally, use the

following URL:
|
|
<literallayout class='monospaced'>
|
|
http://127.0.0.1:8000/admin
|
|
</literallayout>

You can use the Django administration interface to set Toaster

configuration parameters such as the build directory, layer sources,

|
default variable values, and BitBake versions.

The Toaster root directory <filename>TOASTER_DIR</filename>

|
|
<literallayout class="monospaced">

/var/www/toaster/poky

This section only applies if you have set up Toaster

|
|
<para>
|
|
When you create a project in Toaster, you will be asked to
|
|
provide a name and to select a Yocto Project release.
|
|
One of the release options you will find is called
|
|
"Local Yocto Project".
|
|
<imagedata fileref="figures/new-project.png" align="center" width="9in" />
|
|
</para>
|
|
|
|
<para>
|
|
When you select the "Local Yocto Project" release, Toaster
|
|
will run your builds using the local Yocto
|
|
Project clone you have in your computer: the same clone
|
|
you are using to run Toaster.
|
|
Unless you manually update
|
|
this clone, your builds will always use the same Git revision.
|
|
</para>
|
|
|
|
<para>
|
|
If you select any of the other release options, Toaster
|
|
will fetch the tip of your selected release from the upstream
|
|
<ulink url='https://git.yoctoproject.org'>Yocto Project repository</ulink>
|
|
every time you run a build.
|
|
Fetching this tip effectively
|
|
means that if your selected release is updated upstream, the
|
|
Git revision you are using for your builds will change.
|
|
If you are doing development locally, you might not want this
|
|
change to happen.
|
|
In that case, the "Local Yocto Project"
|
|
release might be the right choice.
|
|
</para>
|
|
|

<para>
|
|
However, the "Local Yocto Project" release
|
|
will not provide you with any compatible layers, other than the
|
|
three core layers that come with the Yocto Project:

If you want to build any other layers, you will need to
|
|
manually import them into your Toaster project, using the
|
|
"Import layer" page.

<title>Building a Specific Recipe Given Multiple Versions</title>
|
|
|
|
<para>
|
|
Occasionally, a layer might provide more than one version of
|
|
the same recipe.
|
|
For example, the <filename>openembedded-core</filename> layer
|
|
provides two versions of the <filename>bash</filename> recipe
|
|
(i.e. 3.2.48 and 4.3.30-r0) and two versions of the
|
|
<filename>which</filename> recipe (i.e. 2.21 and 2.18).
|
|
The following figure shows this exact scenario:
|
|
<imagedata fileref="figures/bash-oecore.png" align="center" width="9in" depth="6in" />
|
|
</para>
|
|
|
|
<para>
|
|
By default, the OpenEmbedded build system builds one of the
|
|
two recipes.
|
|
For the <filename>bash</filename> case, version 4.3.30-r0 is
|
|
built by default.
|
|
Unfortunately, Toaster as it exists, is not able to override
|
|
the default recipe version.
|
|
If you would like to build bash 3.2.48, you need to set the
|
|
<ulink url='&YOCTO_DOCS_REF_URL;#var-PREFERRED_VERSION'><filename>PREFERRED_VERSION</filename></ulink>
|
|
variable.
|
|
You can do so from Toaster, using the "Add variable" form,
|
|
which is available in the "BitBake variables" page of the
|
|
project configuration section as shown in the following screen:
|
|
<imagedata fileref="figures/add-variable.png" align="center" width="9in" depth="6in" />
|
|
</para>
|
|
|
|
<para>
|
|
To specify <filename>bash</filename> 3.2.48 as the version to build,
|
|
enter "PREFERRED_VERSION_bash" in the "Variable" field, and "3.2.48"
|
|
in the "Value" field.
|
|
Next, click the "Add variable" button:
|
|
<imagedata fileref="figures/set-variable.png" align="center" width="9in" depth="6in" />
|
|
</para>
|
|
|
|
<para>
|
|
After clicking the "Add variable" button, the settings for
|
|
<filename>PREFERRED_VERSION</filename> are added to the bottom
|
|
of the BitBake variables list.
|
|
With these settings, the OpenEmbedded build system builds the
|
|
desired version of the recipe rather than the default version:

|
