Explore the third installment of a series on solving Devicetree issues in this 44-minute conference talk by Frank Rowand from Sony. Delve into new tools and techniques recently added to Linux mainline or under active development, aimed at making Devicetree usage less painful and more efficient. Learn about improved methods for developing correct system descriptions and drivers, as well as ways to identify and understand errors more easily. Gain insights into different concepts, including printing, sorting messages, naming conventions, status reporting, and output formatting. Examine practical examples such as probe device graphs and interrupt parent scenarios. Discover how to leverage boot logs, understand the role of Devicetree in the bootloader process, and utilize tracepoints for debugging. Benefit from Frank Rowand's extensive experience in Linux kernel development and his role as a Devicetree maintainer to enhance your understanding of this crucial component in embedded systems.
