IWR1642BOOST: What happens if we create binary only for MSS and deploy it to the Radar board?

Tool/software:

Hi , 

I am trying to understand the deployment process of TI Radar.  I am referring to Image Creator User guide.  

file:///C:/ti/mmwave_sdk_03_06_00_00-LTS/packages/scripts/ImageCreator/Image_Creator_User_Guide.pdf

I understand that I can create the Multicore Image from all the RPRC images using the following command.

$ MulticoreImageGen.exe <ENDIAN> <Dev Id> <Shared memory alloc> <App out file>
<Core Id 1> <RPRC inp file for Core Id 1> [<Core Id n> <RPRC inp file for Core Id n> ...]

What happens If I only specify image for MSS core? In this case which code will run in BSS and DSS core?  

Do I need images for all 3 cores to use the above command?

Thanks 

Regards
