Hi,

when i dont put argument Dmcuboot_OVERLAY_CONFIG it gets build and then i flash it successfully

so i went RUNNING DFU PROCESS i have installed mcumgr and in when i do step no 27, i dont get the image that is shown in step no 28 of the below link.

devzone.nordicsemi.com/.../device-firmware-update-dfu-with-mcuboot-bootloader

Hi

I forgot that you also need to rename the file inside the child_image folder to mcuboot to mcuboot.conf.
Then your folder structure will look like this:

To check that the settings are set correctly, you can do:

west build -b nrf52840dk_nrf52840 -–pristine -t mcuboot_menuconfig

and verify that the "Flash space reserved" as explained in step 10 is already set as what you set it to in the configuration.

Hi Sigurd Hellesvik,

With your suggestion i was able to flash the bootloader but when i come step 31 and write this command

mcumgr --conntype serial --connstring "/dev/<your_serial_port_name>,baud=115200" image list.

it gives error nmp timeout in ubuntu
