DOUBT IN ZIP FILE GENERATION FOR OTA -DFU.

[NANDHU]

HI ,

  I need the nrfutil commands used to generate the following zip file

1. softdevice only
2. bootloader only
3. softdevice + bootloader  
4. softdevice +bootloader+application 

If you can please attach the  command used for generating each zip file in the reply ,please don't provide any link because it  time consuming. 

please answer to 1,2,3 and 4 only.

Hi Nandhu,

You run following commands to generate an unsigned package:

1. nrfutil pkg generate --softdevice softdevice.hex dfu_package.zip

2. nrfutil pkg generate --bootloader bootloader.hex dfu_package.zip

3. nrfutil pkg generate --softdevice softdevice.hex --bootloader bootloader.hex dfu_package.zip

4. nrfutil pkg generate --softdevice softdevice.hex --bootloader bootloader.hex --application app.hex dfu_package.zip

Example on a signed package:

nrfutil pkg generate --hw-version 52 --application-version 1 --application application.hex --sd-req 0x98 --softdevice softdevice.hex --bootloader bootloader.hex --key-file private.key app_bl_sd_dfu_package.zip
