Abstract: In the last few years, the need for compact and embedded systems has expanded in all fields. With regard to this development, ARM development platform is the ideal and practical answer for planning a new product design. ARM platforms carry a generally positive result regarding speed, accuracy, adaptability, size and cost. Every new embedded design, at the back an operating system must be modified appropriately for the specifications of the embedded target. It would be a huge added advantage to have an embedded design running an OS. In particular, this paper underlines the BSP (Board Support Package) customization of Linux operating system and porting mechanism to FreeScale SabreSD an i.MX6 processor based embedded board with the help of Yocto build environment. The usual method of going for Linux Target Image Builder (LTIB) is considered old and Yocto is specifically preferred as Freescale is emphasizing on lighter and easier version. Yocto is a dream project by Freescale. Successful build of Yocto environment enables customization of kernel, through which images of OS are built and they are ported to target platform.
