Hi,
I am trying to add OTA DFU functionality to our project using 1-stage MCUBoot. It works fine when I use the default key, I can update OTA firmware. To add a custom key to project, I followed these steps:
1. Added: set(mcuboot_CONF_FILE "${CMAKE_CURRENT_SOURCE_DIR}/mcuboot.conf") to CMakeLists.txt
2. Created: mcuboot.conf file and added:
CONFIG_BOOT_SIGNATURE_TYPE_ECDSA_P256=n
CONFIG_BOOT_SIGNATURE_TYPE_RSA=y
CONFIG_BOOT_SIGNATURE_KEY_FILE="priv.pem"
3. Created a custom key using: openssl genrsa -out priv.pem 2048 ,key is in application folder.
I get the following issue during compilation:
warning: FLASH_MAP (defined at c:\repo\firmware-rtos\build\subsys\storage\flash_map\Kconfig:10) has direct dependencies FLASH_HAS_DRIVER_ENABLED with value n, but is currently being y-selected by the following symbols:
- MCUBOOT_DEVICE_SETTINGS (defined at C:\ncs\v2.0.0\bootloader\mcuboot\boot\zephyr\Kconfig:715), with value y, direct dependencies y (value: y)
error: Aborting due to Kconfig warnings
Device has flash driver enabled:
CONFIG_FLASH=y
CONFIG_FLASH_PAGE_LAYOUT=y
CONFIG_FLASH_MAP=y
CONFIG_SPI=y
CONFIG_SPI_NOR=y

SDK 2.0.0
