     202 * the {{{-c}}} parameter tells repo to just pull down the current branch specified by the manifest file (thus is more network and disk usage efficient)
     203 * the {{{-j}}} parameter tells repo to use multiple processes (8 in this example) which will speed up fetching
     204 * you can later repeat the {{{repo sync}}} to pull down the latest sources specified for the repo manifest file for the current branch specified in the repo init in step 2 above

     2126. Build a filesystem image recipe. gateworks-image-multimedia is recommended.
     213{{{#!bash

     216 * For a detailed description of the Gateworks specific images, please see the images page.
     217 * This could take several hours depending on your Internet speed and development host
     218 * {{{core-image-minimal}}} results in 1.8GB of downloaded sources, 14GB of space used in build/tmp, and takes ~70mins  on a Quad-core 2.5GHz build host, not accounting for your network connection.

    329 The most common build failure (of any linux build system) is failure to be able to fetch sources for the 100's of <a class="missing wiki">OpenSource?</a> projects the build system uses from the Internet. This can be caused by a network issue on your end, a network issue on the source package sites end, or a site/file that has been permanently moved/removed.
    330 </p>
    331 <p>
    332 If this occurs you will see an 'ERROR: Function failed: Fetcher failure' message such as the following output from <tt>bitbake</tt>:

    336 If you encounter such an error the most obvious thing to make sure your Internet connection is solid and try first is simply <tt>bitbake</tt> your desired package again. If it occurs again, its likely an issue on the site that the package URI specifies as the package source. This could be a temporary issue, or the site/file could have been permanently moved/removed for some reason and your either building an older BSP or the package source simply hasn't been updated to deal with the change (as I mentioned, this is a common issue).
    337 </p>
    338 <p>
    339 To combat this issue, there are mirrors where you may be able to find the missing file(s).

Once you find the file, copy it to your download directory, touch the file indicating the fetch is done (the source file with a .done on the end) and <tt>bitbake</tt> your package again. For example, the above shows a failure to fetch the <tt>evtest-1.25.tar.bz2</tt> file:

     269
     270=== Upstream Breakage ===
    347271It is not uncommon for community based projects such as Yocto to encounter build failures after changes because of the complexity of the build system. In some cases breakage may occur simply because of collisions between upstream Yocto repos and the packages that Gateworks overrides.
    348 </p>
    349 <p>
    350 If you are building an 'un-pinned' release (you are not using a snapshot of the manifest file which has sha revisions for each repository) and you encounter a build failure, you may want to switch to a manifest file that produced a successful build by the Gateworks nightly build server. Manifests point to source code repositories by network server and branch, but typically do not pin the branch to a specific repository commit. A 'pinned' snapshot can be used instead that does specify a specific commit of each repository and branch. Refer to step 3 in the <a class="wiki" href="/wiki/Yocto/Building#build">instructions above</a>

    357 When building projects that use multiple source repositories any repository may change and thus make your working directory out of date. Because Yocto uses several package feeds with their own repositories this can make it difficult to keep in sync - this is where the <tt>repo</tt> tool comes in handy.
    358 </p>
    359 <p>
    360 The <tt>repo sync</tt> command will update all repositories with upstream changes:

     276== Keeping up to date and/or pinning source with repo ==
     277When building projects that use multiple source repositories any repository may change and thus make your working directory out of date. Because Yocto uses several package feeds with their own repositories this can make it difficult to keep in sync - this is where the {{{repo}}} tool comes in handy.
     278
     279The {{{repo sync}}} command will update all repositories with upstream changes:
     280{{{#!bash
     281repo sync --quiet
     282}}}
     283
    364284You can override the default Manifest by using a local manifest file if you want to keep in sync with the upstream manifest yet make some minor change like pin a specific project or add a couple of projects. Reasons for doing this could be:
    365 </p>
    366 <ul><li>adding new projects
    367 </li><li>pinning certain projects
    368 </li><li>removing certain projects
    369 </li></ul><p>
    370 To use a local manifest create <tt>.repo/local_manifest.xml</tt> and it will be merged with <tt>.repo/manifest.xml</tt> by the <tt>repo</tt> tool whenever the manifest is used. You can use the <tt>remove-project</tt> directive to remove a project that you don't want and even add it back with your own choices if you want something different. For example:
    371 </p>
    372 <div class="code"><pre><span class="cp">&lt;?xml version="1.0" encoding="UTF-8"?&gt;</span>
    373 <span class="nt">&lt;manifest&gt;</span>

    376 <span class="nt">&lt;/manifest&gt;</span>
    377 </pre></div><p>
    378 The <tt>repo manifest</tt> command will create a snapshot of your current project's manifest allowing you to create a pinned version that can be used later to create a working directory with the various projects at the exact same state as your current working directory:
    379 </p>
    380 <div class="code"><pre>repo manifest -o snapshot.xml -r
    381 </pre></div><p>
    382 This snapshot can then be copied over <tt>.repo/manifest.xml</tt> in a different build directory to pin the repository sources.
    383 </p>
    384 <p>
    385 The Gateworks nightly build server creates a manifest snapshot like this and uploads the latest successful build to <a class="ext-link" href="http://dev.gateworks/com/yocto"><span class="icon">​</span>http://dev.gateworks/com/yocto</a> so that it can be used to re-create a successful nightly build.

     285 * adding new projects
     286 * pinning certain projects
     287 * removing certain projects
     288
     289To use a local manifest create {{{.repo/local_manifest.xml}}} and it will be merged with {{{.repo/manifest.xml}}} by the {{{repo}}} tool whenever the manifest is used. You can use the {{{remove-project}}} directive to remove a project that you don't want and even add it back with your own choices if you want something different. For example:
     290{{{#!bash
     291<?xml version="1.0" encoding="UTF-8"?>
     292<manifest>
     293   <remove-project path="hardware/qcom/display" name="CyanogenMod/android_hardware_qcom_display" />
     294   <project path="hardware/qcom/display" name="WinSuk/android_hardware_qcom_display" />
     295</manifest>
     296}}}
     297
     298The {{{repo manifest}}} command will create a snapshot of your current project's manifest allowing you to create a pinned version that can be used later to create a working directory with the various projects at the exact same state as your current working directory:
     299{{{#!bash
     300repo manifest -o snapshot.xml -r
     301}}}
     302
     303This snapshot can then be copied over {{{.repo/manifest.xml}}} in a different build directory to pin the repository sources.
     304
     305The Gateworks nightly build server creates a manifest snapshot like this and uploads the latest successful build to ​http://dev.gateworks/com/yocto so that it can be used to re-create a successful nightly build.

     313== Updating and rebuilding ==
    399314From time to time the various repositories including in the Yocto build (a combination of Gateworks packages, community packages, Freescale community packages, and Yocto community packages) will get updates to various packages to add features or resolve issues.
    400 </p>
    401 <p>
    402 The <tt>repo</tt> tool which manages the set of repositories in your yocto directory (based on a package manifest) can 'sync' all repos to the latest state using the following in the main yocto directory (the directory containing the sources and build subdirs:
    403 </p>
    404 <div class="code"><pre>./repo sync
    405 </pre></div><p>
    406 Following a sync, you can <tt>bitbake</tt> your filesystem image again to build a new filesystem with all updates:
    407 </p>
    408 <div class="code"><pre><span class="c"># activate a bitbake shell if not already done

     330== Disk usage and keeping things clean ==
    414331Yocto builds can chew up a lot of disk space (true really of any OS build system).
    415 </p>
    416 <p>
    417 <tt>Bitbake</tt> will keep copies of all workdirs for old packages, so over time if you update recipes (or <tt>repo sync</tt> which may update recipes) your disk usage will grow. You can safely remove the old packages manually from <tt>build/tmp</tt> if you wish, or use <tt>bitbake -cclean &lt;recipe.bb&gt;</tt> to clean specific recipes (note that <tt>bitbake -cclean &lt;package&gt;</tt> will only clean the current preferred version, not old packages).
    418 </p>
    419 <p>
    420 Another thing that can cause disk usage bloat is filesystem images. Each time you build a filesystem image (ie gateworks-image-*) <tt>bitbake</tt> will create a new one with a timestamp in <tt>build/tmp/deploy/images/</tt> and the build system will keep around several artifacts such as the filesystem tarball, the ubifs, and the ubi (thus a filesystem image resulting in a 100MB UBI actually chews up over 300MB of disk space each time you build it depending on compression). Its very likely that if you are re-building an image, you probably don't care about the old ones, so you might want to get in the habit of removing them before building. For example, if you want to build gateworks-image-multimedia:
    421 </p>
    422 <div class="code"><pre>rm -rf build/tmp/deploy/images/gateworks-image-multimedia* ;<span class="c"># remove old images we don't care about
    423 </span>bitbake gateworks-image-multimedia ;<span class="c"># build a new one
    424 </span></pre></div><p>
     332
     333Bitbake will keep copies of all workdirs for old packages, so over time if you update recipes (or {{{repo sync}}} which may update recipes) your disk usage will grow. You can safely remove the old packages manually from build/tmp if you wish, or use {{{bitbake -cclean <recipe.bb>}}} to clean specific recipes (note that {{{bitbake -cclean <package>}}} will only clean the current preferred version, not old packages).
     334
     335Another thing that can cause disk usage bloat is filesystem images. Each time you build a filesystem image (ie gateworks-image-*) {{{bitbake}}} will create a new one with a timestamp in {{{build/tmp/deploy/images/}}} and the build system will keep around several artifacts such as the filesystem tarball, the ubifs, and the ubi (thus a filesystem image resulting in a 100MB UBI actually chews up over 300MB of disk space each time you build it depending on compression).

     337rm -rf build/tmp/deploy/images/gateworks-image-multimedia* ;# remove old images we don't care about

    468 Boards with a NAND FLASH large enough to accommodate your image (Ventana boards have a 256MB NAND flash by default which is large enough for fsl-image-multimedia) can have the UBI filesystem created by the build process placed on them. A ubi image will be built in tmp/deploy/images directory alongside the kernel and filesystem tarballs. The ubi image will end with _normal.ubi which is suitable for standard NAND flash sizes on Ventana boards. If you have a Ventana with a 1GB or larger NAND device, you need to build for the 'large' NAND flash layout which you can do by changing the UBI_CONFIG variable in <tt>sources/meta-gateworks/conf/machine/ventana.conf</tt> from 'normal' to 'large' which will result in a ubi image ending with <tt>_large.ubi</tt>.
