DTS Preprocessor and Compiler Script

This script preprocesses Device Tree Source (DTS) files using the C preprocessor (cpp) and compiles them into Device Tree Blob (DTB) or Device Tree Overlay (DTBO) files using dtc. It provides a convenient way to preprocess and compile DTS files for embedded systems development, particularly targeting the ARM architecture.

Usage

The script accepts the following command-line arguments:

-i, --input      Input DTS file
-o, --output     Output format (dtb, dts, or dtbo)
-h, --help       Display help menu

Examples

  1. Preprocess a DTS file and generate a DTB file:

    ./makedtb -i input_filename.dts -o dtb

  2. Preprocess a DTS file and generate a DTBO file:

    ./makedtb -i input_filename.dts -o dtbo

  3. Preprocess a DTS file and keep it as DTS:

    ./makedtb -i input_filename.dts -o dts

Requirements

Make sure to have these installed on your system before running the script. Google is your friend to know how to get them for your distribution.

  • arm-none-eabi-cpp: C preprocessor for the ARM architecture.
  • dtc: Device Tree Compiler.
