Help¶

When building a bootloader firmware this option adds a vector table relay handler and a vector relay table, to relay interrupts based on a vector table pointer. This is only required but not limited to Cortex-M Baseline CPUs with no hardware vector table relocation mechanisms (e.g. VTOR).

Direct dependencies¶

(ARMV6_M_ARMV8_M_BASELINE || ARMV7_M_ARMV8_M_MAINLINE) && CPU_CORTEX_M && !ARM64 && ARM

(Includes any dependencies from ifs and menus.)

Defaults¶

No defaults. Implicitly defaults to n.
