RE: nrfutil create DFU zip file

after searching there is no key. so for future reference the following steps needs to be taken:

1. generate keys

2. update "secure_bootloader"

3. flash buttonless dfu

4. sign application with private key

5. update application

I tested that and it's working great

I think I have found the reason.

using nrfutil pkg display and comparing the pre-generated "hrs_application_s132.zip" I have composed the following command:

nrfutil pkg generate --debug-mode --application hrs_application_s132.hex app_dfu_package.zip --hw-version 52 --sd-req 0xCAFE,0xAF --application-version 1 --app-boot-validation NO_VALIDATION

but, it seems that the "hrs_application_s132.zip" was signed with .pem key.

in order to create a reference zip file I need that key, where is it located?

thank you
