CCS/TMS320F28379D: Code debugging

Part Number: TMS320F28379D

Tool/software: Code Composer Studio

Hello,

I am using the tms320f28379d microcontroller and working with USB communication. Using PUTTY as the terminal, everytime I debug the program and open PUTTY for the first time I am able to get an output. But if I try to close PUTTY and reopen it again while the program is running the screen remains blank, I have to debug the program again and reopen the terminal to get the program to work. I also tried to couple the controller to a matlab gui. The first time when COM is opened I am able to get the program to work but everytime I try to close the serial port and reopen it again, there is a timeout error when a write function to the microcontroller is called. Anyone has any idea why this is happening? TIA.
