CONFIG_BOOTLOADER_MCUBOOT¶
MCUboot bootloader support
Type: bool
Help¶
This option signifies that the target uses MCUboot as a bootloader, or in other words that the image is to be chain-loaded by MCUboot. This sets several required build system and Device Tree options in order for the image generated to be bootable using the MCUboot open source bootloader. Currently this includes:
Setting TEXT_SECTION_OFFSET to a default value that allows space for the MCUboot image header
Activating SW_VECTOR_RELAY on Cortex-M0 (or Armv8-M baseline) targets with no built-in vector relocation mechanisms
Including dts/common/mcuboot.overlay when building the Device Tree in order to place and link the image at the slot0 offset
Defaults¶
No defaults. Implicitly defaults to n.
