Hello, 
 You can add the --nrf21540 option to the end of your build command, for example if you are building for the gateway, both cores and the debug version, your build command will look like this: 
 python .	ools\buildprog\buildprog.py -c both -d gateway -b debug --nrf21540 
 Best regards, 
 Maria
