merge settings bootloader error

[kxct]

你好

My English is very poor, please forgive me.

 SDK：12.3

 示例：nRF5_SDK_12.3.0_d7731ad \ examples \ dfu \ bootloader_secure \ pca10028 \ arm5_no_packs

我使用以下命令：

//generate  setting.hex

nrfutil settings generate --family NRF51 --application application.hex --application-version 1 --bootloader-version 1 --bl-settings-version 1 ./hex/settings.hex



//mergehex bootloader.hex settings.hex

mergehex -m bootloader.hex  settings.hex -o FW_multiple.hex

output error:

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

I try bootloader_secure debug example(nRF5_SDK_12.3.0_d7731ad\examples\dfu\bootloader_secure\pca10028_debug\arm5_no_packs),Bootloader and settings can be successfully merged.

I need your help.

The cause of the problem has been found. Nrfutil tool adds new options: --no-backup   I have not noticed.
