The purpose of this thesis was to develop an Embedded Linux distribution for a customed Arm-based board named KK2040 of Procemex Company. This aim was achieved by using the Yocto Project set of tools. During this thesis, the Yocto project technologies as well as the Linux platform were studied from the point of view how to integrate software development and update it to the device hardware. All these outputs are represented by a camera image which contains the built Yocto project and its layers.
