This directory receives complete filesystem images.
If you want to flash the resulting image from a build onto a device, look here for the image.

<para>
Note, you should not remove any files from this directory by hand in an attempt
to rebuild an image.
If you want to clean out the cache, re-run the build using the following
BitBake command:
Be careful when deleting files in this directory.
You can safely delete old images from this directory (e.g.
<filename>core-image-*</filename>, <filename>hob-image-*</filename>,
etc.).
However, the kernel (<filename>*zImage*</filename>, <filename>*uImage*</filename>, etc.),
bootloader and other supplementary files might be deployed here prior to building an
image.
Because these files, however, are not directly produced from the image, if you
delete them they will not be automatically re-created when you build the image again.
</para>
<para>
If you do accidentally delete files here, you will need to force them to be
re-created.
In order to do that, you will need to know the target that produced them.
For example, these commands rebuild and re-create the kernel files:
<literallayout class='monospaced'>
$ bitbake -c cleanall &lt;target&gt;
$ bitbake -c clean virtual/kernel
$ bitbake virtual/kernel
</literallayout>
