MSP430G2553 Launchpad does not connect when P1.6 jumper is open

Hi,

   I complied and loaded a program using MSP430G2553 Launchpad. I want to use a booster board and have to remove jumper P1.6. As soon as I remove jumper P1.6 the board can no longer talk to CCS 

CCS V6.1.3 on Windows 10.

Any help will be much appreciated.

Thanks and Regards,

Pavan
