CONFIG_HW_STACK_PROTECTION¶

Hardware Stack Protection

Type: bool

Help¶

Select this option to enable hardware-based platform features to
catch stack overflows when the system is running in privileged
mode. If CONFIG_USERSPACE is not enabled, the system is always
running in privileged mode.

Note that this does not necessarily prevent corruption and assertions
about the overall system state when a fault is triggered cannot be
made.

Direct dependencies¶

BOARD_TWR_KE18F || ARCH_HAS_STACK_PROTECTION

(Includes any dependencies from ifs and menus.)

Default¶

y if !USERSPACE
