CONFIG_ARM_STACK_PROTECTION

(No prompt – not directly user assignable.)

Type: bool

Help

This option enables either: - The built-in Stack Pointer limit checking, or - the MPU-based stack guard to cause a system fatal error if the bounds of the current process stack are overflowed. The two stack guard options are mutually exclusive. The selection of the built-in Stack Pointer limit checking is prioritized over the MPU-based stack guard.
