Hi,

Try to add a space between "0xAE" and "--key-file".

Thanks sigurd  for your reply.

The following command is used for generation of dfu.zip packet

nrfutil pkg generate --hw-version 52 --application-version 1 --application bt_bl_0.hex --sd-req 0xAE --key-file private.key app_dfu_package.zip

here bt_bl_0.hex is the hex file of my secure bootloader application .

Please Correct me if am wrong.

Am unable to resolve this issue

Do you have the bt_bl__0.hex in the 20148026 folder?

If you use the command dir , what does it print?

If you are creating a DFU package for a bootloader update, use --bootloader instead of --application.
