Building a custom image

[mladen]

Ångström images can be customized to satisfy particular requirements. Building a custom image is simple like building of custom recipe. We are going to use minimal-image as template, but in addition to add some extra packages

Code: Select all

mkdir -p /angstrom/sources/local/recipes/images

Add new file for custom image

Code: Select all

nano /angstrom/sources/local/recipes/images/minimal-osgi.bb

with the following content

Code: Select all

require ${BBFILE_PATTERN_oe}/recipes/images/minimal-image.bb

IMAGE_INSTALL += "\
        jamvm \
        nano \
        librxtx-jni \
        mladen \
        "

export IMAGE_BASENAME = "minimal-osgi"

By creating a custom image, a developer has total control over the contents of the image. It is important use the correct names of packages in the “IMAGE_INSTALL” variable. The names must be in the OpenEmbedded notation instead of Debian notation, for example "glibc-dev" instead of "libc6-dev" etc. Run building of image:

Code: Select all

bitbake minimal-osgi

After building image file could be found here:

Code: Select all
