CONFIG_RUNTIME_NMI¶

Attach an NMI handler at runtime

Type: bool

Help¶

The kernel provides a simple NMI handler that simply hangs in a tight loop if triggered. This fills the requirement that there must be an NMI handler installed when the CPU boots. If a custom handler is needed, enable this option and attach it via _NmiHandlerSet().

Direct dependencies¶

CPU_CORTEX_M && ARM

(Includes any dependencies from if’s and menus.)

Defaults¶

No defaults. Implicitly defaults to n.

Symbols selected by this symbol¶
