mergehex ERROR: The hex files cannot be merged since there are conflicts

[RahulR]

I have built boot-loader hex file from SDK 12.1.0 secure DFU project, without any changes except for public_key.c file.

I am referring to steps mentioned under

Combine application, bootloader and softdevice image - Bootloader setting

Is this applicable for the SDK version 12.1.0 and nrf51?

[Edvin]

It should be applicable for SDK12.1.0.

What version of nrfutil do you use? Use the command "nrfutil version" to find the version.

What commands did you use to generate the files (BL settings if you use it), and what commands did you use to merge the files?

Best regards,

Edvin
