    The video mentions at the end about overlay device tree to avoid compiling the entire kernel for adding one new device. Where can I learn more about it? Do you have a video diving deeper into that as well?

      For device tree overlays i already have made some videos. This is the first one. Just follow the Playlist ruclips.net/video/YxDEdpHTEP8/видео.html
      In the future I will make some more videos how to directly make changes to the device tree without overlays.

    Hi! Who deliver the device tree? Board firmware that contain information about the nodes?

      Hi.
      Let's take the TI's AM335x chip which is used on the beaglebone black as an example. TI offers an evaluation board for the chip and a Linux SDK for building a Linux Image for the board. The device tree is part of the SDK. If you download and install it, you can find the device tree files in ti-processor-sdk-linux-rt-am335x-evm-08.02.00.24/board-support/linux-rt-5.10.100+gitAUTOINC+204ec708dc-g204ec708dc/arch/arm/boot/dts
      Now if you want to build a custom PCB with the AM335x chip, you can take this device tree as an example and change it according to your needs.
