CONFIG_SW_VECTOR_RELAY

Enable Software Vector Relay

Type: bool

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 && ARM

(Includes any dependencies from ifs and menus.)

Defaults

No defaults. Implicitly defaults to n.
