Hello,

To customize the device tree on your Toradex hardware, you will need to set up a kernel build environment. Here are the steps you should follow:

  1. Set Up the Build Environment: Before you begin, ensure that you have a Linux kernel build environment ready. This is a prerequisite for compiling the device tree. You can find more information on setting up the environment here.

  2. Locate the Device Tree Source Code: For 32-bit modules, including the imx6dl, the device tree source files are located in the following directory:

    • /arch/arm/boot/dts/
      More details can be found here.

  3. Compile the Customized Device Tree: Use the following command to compile your customized device tree:

    $ make DTC_FLAGS="-@" <device-tree>.dtb

    This command is explained further here.

  4. Deploy the Compiled Device Tree: Once compiled, the device tree should be deployed to the /boot directory of your embedded Linux image. More information is available here.

The device tree is a data structure that describes the hardware configuration, including not only the SoC’s internal memory-mapped peripherals but also the entire hardware of the carrier board. You can learn more about device trees here.

I hope this helps you with your customization process.
