CONFIG_SW_VECTOR_RELAY¶
Enable Software Vector Relay
Type: bool
Help¶
Add Vector Table relay handler and relay vector table, to relay interrupts based on a vector table pointer. This is only required for Cortex-M0 (or an Armv8-M baseline core) with no hardware vector table relocation mechanisms or for Cortex-M0+ (or an Armv8-M baseline core) with no VTOR and no other hardware relocation table mechanisms.
