You need to provide which SDK you are using. Always stick to the documentation on infocenter. If you are using SDK v12, please see this.

i installed python, and nrfutil.exe, when i enter nrfutil.exe dfu genpkg --application-version 1 --application ble_app_beacon_pca10040_s132.hex beacon.zip

Error: No such command "genpkg"

Please follow the documentation. It says "Run nrfutil pkg generate --help to display help about creating a zip file."

So the correct syntax is "nrfutil.exe pkg generate --application ..." and so on, please type nrfjprog.exe and press enter to get help on the syntax and/or have a look here.

it is requesting for key.pem file, how to create this file?

[Hung Bui]

Isn't it in this link, the documentation tell that you should look at "Working with keys" to know how to create the .pem file ?
