kdtc is a wrapper around dtc (the Device Tree compiler) that passes input files through cpp (the C preprocessor) first, in order to resolve any #include directives or expand any #define macros. When run without any dtc options, kdtc attempts to detect the input format and do the right thing.
Build Instructions
Install the prerequisites with "sudo apt install cmake device-tree-compiler" - you need at least version 3.10 of cmake. Run the following commands, either here or in the top-level directory to build and install everything:
- cmake .
- sudo make install
Alternatively, you can just download the latest version using:
$ wget https://raw.githubusercontent.com/raspberrypi/utils/refs/heads/master/kdtc/kdtc
$ chmod +x kdtc
Usage
Usage: kdtc [<opts>] [<infile> [<outfile>]]
where <opts> can be any of:
-h|--help Show this help message
-i|--include <path> Add a path to search for include files
-k|--kerndir <path> The path to the kernel tree
-n|--just-print Just show the command that would be executed
-w|--warnings Don't suppress common dtc warnings
or any dtc options (see 'dtc -h')
When run with no dtc options, kdtc detects the input format and attempts
to do the right thing.
If run within a git kernel source tree, the kerndir path is inferred.
