Hi !

I think it is really erase all components and flash all back :

$ nrfjprog --program merged_domains.hex --recover --verify --reset
[ #################### ] 2.264s | Erase file - Done erasing
[ #################### ] 3.591s | Program file - Done programming
[ #################### ] 3.616s | Verify file - Done verifying
Applying system reset.
Run.

Thank you !

Eugene

Hi,

Take a look at this page:

https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/config_and_build/multi_image.html

Try using merged_domain.hex

nrfjprog --program merged_domains.hex --recover --reset

Hi !

I have my own multi-image build and files

GENERATED_CP_NETWORK_merged_domains.hex

GENERATED_CP_APPLICATION_merged_domains.hex

are not generated without west flash command.

West Flash also try to flash connected boards.

I think it should be a command that just generate flashable files.

Does it possible to have one hex file for flash application and netcore by using nrjprog ?

Regards,

Eugene

Hi,

[quote user=""]After the pristine build "west build --pristine --board nrf5340dk_nrf5340_cpuapp" looks like no any files that can be flashed by nrfjprog are not generated.[/quote]

If you are doing a multi-image build, then they should be located in the folder /build/zephyr , can you check that folder?
