Yocto has an alleged steep learning curve. It can be a challenge for modules and evaluation board manufacturers to add support for their devices in Yocto as they don't necessarily have a software background. This talk will highlight the steps required, techniques and good practices to create a well integrated machine configuration allowing to build images using the Yocto Linux build system. The Crystalfontz support from meta-fsl-arm-extra will be used to illustrate the talk.
