With this dissertation it is pretended to uniformize and simplify the development of embedded systems applications in an industrial environment using a microcontroller with a Linux Operative System generated by Yocto.The selection of the microprocessor family to use in a certain application is closely connected to the cost, performance and power consumption.The processors of the family ARM Cortex-A have an application background, implementing a traditional ARM architecture with multiples modes and support a virtual memory system architecture based on an MMU.Yocto Project provides a flexible toolset and a development environment that allows embedded device developers across the world to collaborate through shared technologies, software stacks, configurations, and best practices used to create these tailored Linux images.
