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:
-
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.
-
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.
-
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.
-
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.
Best regards,
Toradex AI Assistant
