To generate a binary footprint for your board use that sequence of actions:

1. Verify that you are using Zephyr RTOS Release v2.4.0.

   $ git checkout 7a3b253

2. Verify that your version of west is v0.7.3 or higher

   $ west --version

3. Build an application using the command:

   $ west build -b <your_board_name> tests/benchmarks/footprints/

4. To view the ROM results output run.

   $ west build -t rom_report

   The result will be a list of all compiled objects and their ROM usage in a tabular form with bytes per symbol and the percentage it uses.

5. To view the RAM results output run.

   $ west build -t ram_report

   The result will be a list of all compiled objects and their RAM usage in a tabular form with bytes per symbol and the percentage it uses.
