overlaycheck is a tool for validating the overlay files and README in a kernel source tree. Note that overlaycheck makes use of ovmerge, dtmerge, dtc, dtdiff and fdtget, and therefore requires them all to be installed and on the path.

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 .
• make
• sudo make install

Usage

• overlaycheck
• overlaycheck -v (for verbose output)
• overlaycheck -s (to see all the strict warnings from dtc)
