Creating Your Own Tiny Linux Distribution Using Yocto: Keeping it Small With Poky-Tiny - Alejandro Hernandez, Xilinx

 Poky-tiny was created in 2011, it is a reference distro provided by the Yocto project that is meant for resource-constrained embedded devices.

It provides a “fully” running Linux OS, with the most basic functionality, by using software like busybox, musl, and dropbear to provide common UNIX utilities, a lightweight, yet compatible and efficient C library and a Secure Shell (ssh) server-client respectively.

In this presentation, Alejandro will talk about the latest changes that have been made to poky-tiny, explaining concepts such as a DISTRO layer to present how it is built and how users can easily customize it to create their own Tiny Linux, he will also go through the process of how the distribution is kept small, analyze the size of the kernel and rootfs and a new image core-image-tiny-initramfs that boots to RAM for faster boot time, comparing that to other images as an example.
