# Makefile for building mcuboot as a Zephyr project.

# Configuration choices.

#####################
# Signature algorithm
#####################
# Choose one of RSA or ECDSA P-256 blocks, and uncomment the config
# lines there, and comment out any other blocks.

# RSA
CONF_FILE = boot/zephyr/prj.conf
CFLAGS += -DMCUBOOT_SIGN_RSA -DMCUBOOT_USE_MBED_TLS

# Newer uses should use the RSA-PSS signature algorithm.  This define
# enables (and requires) this type of signature.
#CFLAGS += -DMCUBOOT_RSA_PKCS1_15

# ECDSA P-256
#CONF_FILE = boot/zephyr/prj-p256.conf
#CFLAGS += -DMCUBOOT_SIGN_EC256 -DMCUBOOT_USE_TINYCRYPT

# Enable this option to have the bootloader verify the signature of
# the primary image upon every boot.  Without it, signature
# verification only happens on upgrade.
CFLAGS += -DMCUBOOT_VALIDATE_SLOT0

# Enabling this option uses newer flash map APIs. This saves RAM and
# avoids deprecated API usage.
#
# (This can be deleted when flash_area_to_sectors() is removed instead
# of simply deprecated.)
CFLAGS += -DMCUBOOT_USE_FLASH_AREA_GET_SECTORS

# Enable this option to not use the swapping code and just overwrite
# the image on upgrade.
#CFLAGS += -DMCUBOOT_OVERWRITE_ONLY
