DFU zip packet error

[Murugan]

Dear Nordic Team,

Thanks for support.

I try to make zip file generation using command promt as per the nordic document(How to generate the INIT file for the DFU.pdf). Command : nrf dfu genpkg --application [application].hex --application-version [version] --softdevice [softdevice].hex --bootloader [bootloader].hex --dev-type [type] --dev-revision [revision] --sd-req [list of supported Soft Device ids] [name of the distribution packet].zip

Zip file was successfully generated but it contain the two bin files and two .dat file. But in example file contain one bin file and one dat file.

I want to know it was correct procedure?????

Hi Murugan,

Yes, if you have provided nrfutil with an application.hex, a softdevice.hex and/or a bootloader.hex, i.e.

nrf dfu genpkg --application application.hex --application-version 0xFFFFFFFF  --softdevice softdevice.hex --bootloader bootloader.hex --dev-type 0xFFFF --dev-revision 0xFFFF --sd-req 0xFFFE distribution_packet.zip

then the softdevice.hex and bootloader.hex will be merged and converted into one .bin file, and the application.hex is converted to the second .bin file.

If you generate a distribution zip with an application image only, as the example zip, then there will only be one .bin file in the zip.

Have you added the location of nrfutil.exe to your PATH? Is the SD,BT and AP.hex files in the same directory from where you are running the terminal ?

Now working fine. Copy all all file in D folder. Remove the DFU Folder.

Now i want to know the if possible all three hex file in one bin file and one dat file.

@murugan : No that is not possible.
