Introduction to the U-Boot bootloader
U-Boot is the universal bootloader used on a vast majority of embedded systems, development kits, products and so on. This session is an introduction into the U-Boot bootloader, including a hands-on part, and covers practical topics like identifying that the board is running U-Boot, accessing and exploring the U-Boot shell, including advanced scripting techniques to make life easier, obtaining information about the current hardware, accessing busses and storage and finally booting the kernel. Furthermore, since every embedded project has it’s unique set of requirements, U-Boot customization topics are briefly touched at the end of the session.

I have been a contractor for multiple companies for many years. My primary responsibility is designing and implementing customer-specific functionality. One important aspect of my work is leveraging the benefits of working inside the mainline Linux, U-Boot and OE / Yocto Project, explaining our customers the benefits of pushing the newly produced code back into mainline and effectively doing the contributions. I am therefore heavily involved with both mainline U-Boot and Linux kernel, be it my role as R-Car, SoC-FPGA or USB maintainer for U-Boot, MTD co-maintainer in Linux or others. My speaking experience includes giving talks at ELCE, LinuxCon Japan, EmbeddedWorld and various smaller events across Europe.
