The project can be compiled and run normally before adding CONFIG_MCUMGR   and other configurations。

The detailed configurations added are as follows：

CONFIG_MCUMGR=y

CONFIG_BOOTLOADER_MCUBOOT=y

CONFIG_MCUMGR_MGMT_NOTIFICATION_HOOKS=y

CONFIG_MCUMGR_CMD_IMG_MGMT=y

CONFIG_MCUMGR_GRP_IMG_STATUS_HOOKS=y

CONFIG_MCUMGR_GRP_IMG_UPLOAD_CHECK_HOOK=y

CONFIG_MCUBOOT_IMAGE_VERSION="2.1.4+0"

After that, there was an error in compiling：

The result was successfully compiled before adding the above configuration：

nrf5340 flash has 1M bytes, which accounts for 16.38% without boot, and it is impossible to add the boot function to exceed the size。

In the nRF Connect SDK, enabling MCUboot will enable the Partition Manager. Use this for partitioning instead.

To fix your issue, add the following to your project folder: child_image/mcuboot.conf:

CONFIG_PM_PARTITION_SIZE_MCUBOOT=0x10000

Or whatever other size you need, but only in steps of 0x1000.

Thanks for your answer，butt after setting it up, a'p'p didn't run.

The specific settings are as follows：

1.Prj.con

[dower]

[Sigurd Hellesvik]

When you use external flash, you must also configure this for MCUboot.
See my unofficial sample or the external flash test

[dower]

I'm using an internal flash

[Sigurd Hellesvik]

Right. In that case try to just set CONFIG_BOOT_MAX_IMG_SECTORS=256 for MCUboot

[dower]

Seems to have some effect，I set 256 ，512 but still no jump to APP

CONFIG_BOOT_MAX_IMG_SECTORS=256 or

CONFIG_BOOT_MAX_IMG_SECTORS=512

[Sigurd Hellesvik]

Hmm

Can you paste all of partitions.yml into Insert->Code in a reply here?

False.

From the partitions.yml that you posted, we can see that mcuboot_secondary is in external flash.

mcuboot_secondary:
  address: 0x1000000
  device: DT_CHOSEN(nordic_pm_ext_flash)
  end_address: 0x10ec000
  placement:
    align:
      start: 0x4
  region: external_flash
  share_size:
  - mcuboot_primary
  size: 0xec000

Use CONFIG_PM_EXTERNAL_FLASH_MCUBOOT_SECONDARY if you want to configure this.
