Several Compilation Errors when compiling MCUBoot for 'nucleo_u575zi_q' board with 'CONFIG_MCUBOOT_SERIAL=y'

[Nick-Chiptech]

Attempting to build MCUBoot for the first time (newish to Zephyr and MCUBoot) but I seem to have genuine compile errors. This is my PRJ.conf. Im just using the MCUBoot that ships with the latest Zephyr 4.3. When I enabled 'CONFIG_MCUBOOT_SERIAL=y' the errors occur.

zephyr : v4.3.0-1013-g8c264d30ea1 mcuboot : v2.2.0-221-gf3cc9476 zephyr-sdk-0.17.4

================================================== prj.conf

CONFIG_PM=n

CONFIG_MAIN_STACK_SIZE=10240

CONFIG_BOOT_SWAP_SAVE_ENCTLV=n

#NRP EDIT CONFIG_BOOT_ENCRYPT_IMAGE=y CONFIG_BOOT_VALIDATE_SLOT0=y CONFIG_BOOT_SIGNATURE_TYPE_RSA=y CONFIG_BOOT_ENCRYPTION_KEY_FILE="enc-rsa2048-priv.pem" CONFIG_BOOT_SIGNATURE_KEY_FILE="root-rsa-2048.pem" CONFIG_NO_OPTIMIZATIONS=n #75kB bigger if yes! CONFIG_BOOT_UPGRADE_ONLY=n CONFIG_BOOT_BOOTSTRAP=y

Enable logging for MCUboot

CONFIG_LOG=y CONFIG_MCUBOOT_LOG_LEVEL_WRN=y CONFIG_UART_CONSOLE=n # Disable UART, since Serial Recovery uses it CONFIG_MCUBOOT_SERIAL=y # Enable Serial Recovery over UART CONFIG_SINGLE_APPLICATION_SLOT=n # Configure the bootloader to use two slots CONFIG_MCUBOOT_INDICATION_LED=y # Turn on a LED so we can see when Serial Recovery mode is active

CONFIG_FLASH=y #CONFIG_MCUMGR=y #CONFIG_NET_BUF=n #wait before jumping to app #CONFIG_BOOT_SERIAL_WAIT_FOR_DFU=y #CONFIG_BOOT_SERIAL_WAIT_FOR_DFU_TIMEOUT=2000

Various Zephyr boards enable features that we don't want.

CONFIG_BT is not set

CONFIG_I2C is not set

CONFIG_LOG_MODE_MINIMAL=y

Ensure Zephyr logging changes don't use more resources

CONFIG_LOG_DEFAULT_LEVEL=0

Use info log level by default

CONFIG_MCUBOOT_LOG_LEVEL_DBG=y

Decrease footprint by ~4 KB in comparison to CBPRINTF_COMPLETE=y

CONFIG_CBPRINTF_NANO=y

Use picolibc to reduce flash usage

CONFIG_PICOLIBC=y

Disable malloc arena because we don't need it

CONFIG_COMMON_LIBC_MALLOC_ARENA_SIZE=0
