How to create combined image after DFU ?

[sing]

Dear all,

Our application is made of Chip nRF518122 + SDK 11.0.0 + DFU Bootloader + BLE application (gcc complied) loaded with nRF Toolbox over the air

we are putting our project into production and need to generate a combined image file for pre-programming the nRF51822 chip.

Is there any way we can extract the programmed image from a chip and use it as a master image for programming all the other chips ?

Here are two similar questions I found.

devzone.nordicsemi.com/.../ devzone.nordicsemi.com/.../

which tried to solve the issue by using the mergehex.exe tool to combine the hex files, as well as adding some custom settings for the DFU app. However the custom settings seem to be changing from version to version. And I wonder how the custom settings should be created corresponding to our SDK 11.0.0 setup.

Any insight ?

Thanks a lot.
