TCPmaker calls the MPFS2 program to turn your content files into a form that can be stored on your device.  When this happens, you will see one or more command line windows appear briefly, one for each compiler that you generate code for. These command windows will disappear automatically, when that part of the process is complete.

You will then see a message from your TCP Advisor, reminding you that you should look at the file ReadMe.txt for build instructions that TCPmaker has provided for each compiler you are generating code for.
