Power consumption increase when adding MCUBOOT with BT OTA DFU

[ananda.nogueira]

Hi,

I'm developing a project using nrf52840 SoC and zephyr v2.5.1.

I have only added this configurations on my project's prj.conf:

#Enable MCUBOOT bootloader build in the application
CONFIG_BOOTLOADER_MCUBOOT=y
#Include MCUMGR and the dependencies in the build
CONFIG_NCS_SAMPLE_MCUMGR_BT_OTA_DFU=y
CONFIG_NCS_SAMPLE_MCUMGR_BT_OTA_DFU_SPEEDUP=y

CONFIG_DISABLE_FLASH_PATCH=y

CONFIG_SYSTEM_WORKQUEUE_STACK_SIZE=2048

After adding MCUBOOT, I noticed a considerable increase in power consumption.

Before adding MCUBOOT:

Is there something I'm missing or something I need to disable?

Best Regards,

Hi

MCUBoot is a "child image", and the build of child images are defined in the project's "child_image" folder (you may need to create one). For MCUBoot this is "child_image/mcuboot.conf" and the overlays are in "child_image/mcuboot/boards".

Best regards,

Simon
