.. title:: SW_VECTOR_RELAY

.. option:: 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).
