Tweaking Freescales Yocto Community BSP Builds

Maurice le Rutte asked me on Twitter if it is possible to add support for the first UDOO board and building a DirectFB enabled image. After some research it looked like a solution for the DirectFB task should be not that big issue.

I guess you have already a running Yocto environment based on the Freescale BSP comunity layers. To build a DirectFB image some tweaking is needed. You have to add those lines to your conf/local.conf

DISTRO_FEATURES_remove = "x11"
DISTRO_FEATURES_remove = "wayland"
DISTRO_FEATURES_append = " directfb"

The first two lines remove support for wayland and X11 which will conflict with DirectFB and will prevent a successful build. With this modification you can build a DirectFB image. The extra white space in front of directfb is mandatory!

bitbake core-image-directfb

This is the right time to fetch some coffee.

Another tweak I prefer to do in the conf/local.conf is switching from RPM to IPK as package manager. It is more lightweight and a little bit faster than RPM or DEB. You only have to change the variable PACKAGE_CLASSES to package_ipk

PACKAGE_CLASSES ?= "package_ipk"

At the moment I am working on a Machine configuration for the UDOO Quad board
