The Device Tree has been adopted for the ARM 32-bit Linux kernel support almost a decade ago, and since then, its usage has expanded to many other CPU architectures in Linux, as well as bootloaders such as U-Boot or Barebox. Even though Device Tree is no longer a new mechanism, developers coming into the embedded Linux world often struggle to understand what Device Trees are, what is their syntax, how they interact with the Linux kernel device drivers, what Device Tree bindings are, and more. This webinar will offer a deep dive into the Device Tree, to jump start new developers in using this description language that is now ubiquitous in the vast majority of embedded Linux projects.

Organized in partnership with ST, this webinar will be illustrated with numerous examples applicable to the STM32MP1 MPU platforms, which make extensive usage of the Device Tree.

This webinar will take place on February 9, 2021, and is proposed at two different times during the day: at 10 AM CET (UTC+1) and 5 PM CET (UTC+1).

Thomas Petazzoni is the CTO of Bootlin, a consulting company specialized in embedded Linux development, offering engineering and training services. Thomas is the author of the popular « Device Tree for Dummies » talk given in 2014 and which helped numerous embedded Linux developers get started with the Device Tree. Thomas has contributed over 900 patches to the official Linux kernel, mainly around ARM hardware platform support. He is also the co-maintainer of the Buildroot open-source project.
