#Kconfig Configuration System
This document describes how to configure MOS using the Kconfig configuration system. For more information on Kconfig, the configuration system itself, please refer to the Kconfig documentation.
The menuconfig tool used by MOS is implemented in Python by Zephyr, you can use ninja menuconfig to open the configuration menu.
Several useful keys are:
↑and↓: Move the cursor up and down.→and←: Enter and exit a submenu.Space: Toggle the selected option.h: Display help and symbol dependencies./: Search for a symbol, the search result list updates in real-time.
#2. Setting Configuration Options via CMake
All parameters that can be set via menuconfig can also be set via CMake command lines. For example, to enable MM_DETAILED_UNHANDLED_FAULT for detailed information about an unhandled page fault, you can run:
Boolean Options
The configuration options are case-insensitive, so you can use either y or Y to enable an option. However, ON is not a valid value for boolean options.
Non-boolean options are also set in the same way:
You can press c to display the configuration name in menuconfig.
CMake-Kconfig Limitation
Currently, setting any options via CMake overrides ALL options modified via menuconfig. But any options set via previous CMake command lines will be preserved.
This will be fixed in the future.
